Full textAbstract:
Smartphone addiction can lead to physical and psychological disorders in users, such as headache, lack of concentration, insomnia, fatigue, increased neck pain and disabilities with reduced range of neck flexion and extension. The main aim of this study was to investigate the association between non - specific neck and shoulder pain and the use of smartphones. A cross - sectional study among 416 undergraduate students from Danang University of Medical Technology and Pharmacy was conducted in 2019. The smartphone addiction scale - short version (SAS-SV) was used to assess smartphone addiction among students while the Neck Disability Index (NDI) scale was used to measure the severity of shoulder pain. Multivariate logistic regression models were used to seek associations between smartphone usage and students’ neck and shoulder pain. The prevalence of smartphone addiction among participants was 46.6%. The average NDI score was 5.31 ± 3.81. The results showed that daily average time using smartphones (p = 0.018) and the posture when using smartphones (p = 0.03) were significantly correlated to the severity of neck and shoulder pain. The multivariate logistic regression models indicated that the factors that have an independent impact on the student’s shoulder and neck pain were gender, school year and the addiction to smartphones. It is recommended to reduce the duration of smartphone use and maintain the proper body posture while using it such as sitting on a chair with a backrest, avoiding unfavorable positions such as lying or standing.

This study assesses the associations of objectively-measured smartphone time with physical activity, sedentary behavior, mood, and sleep patterns among young adults by collecting real-time data of the smartphone screen-state. The sample consisted of 306 college-aged students (mean age ± SD: 20.7 ± 1.4 years; 60% males). Over seven days of time, the following variables were measured in the participants: objectively-measured smartphone use (Your Hour and Screen Time applications), objective and subjective physical activity (GoogleFit and Apple Health applications, and the International Physical Activity Questionnaire (IPAQ), respectively), the number of hours sitting (IPAQ), mood (The Profile of Mood State (POMS)), and sleep (The Pittsburgh Sleep Quality Index (PSQI)). Multiple regressions analyses showed that the number of hours sitting per day, physical activity, and the POMS Global Score significantly predicted smartphone use (adj.R2 = 0.15). Further, participants with low levels of physical activity were more likely to increase the use of smartphones (OR = 2.981). Moreover, mood state (β = 0.185; 95% CI = 0.05, 0.32) and sleep quality (β = 0.076; 95% CI = −0.06, 0.21) predicted smartphone use, with those reporting poor quality of sleep (PSQI index >5) being more likely to use the smartphone (OR = 2.679). In conclusion, there is an association between objectively-measured smartphone use and physical activity, sedentary behavior, mood, and sleep patterns. Those participants with low levels of physical activity, high levels of sedentary behavior, poor mood state, and poor sleep quality were more likely to spend more time using their smartphones.

Full textAbstract:
Excessive use of smartphones has been associated with a number of negative consequences for individuals. Some of these consequences relate to many symptoms of behavioral addiction. The present study aims to investigate whether participants with high levels of smartphone usage may have difficulty with their ability to wield the self-control that is needed to restrict smartphone usage compared to participants with lower levels of smartphone addiction. Specifically, we expect that people with high levels of smartphone usage may have problems in refraining from using a smartphone. In addition, we expect people with a high level of smartphone use may show deficiencies in cognitive tasks such as memory, executive control, and visual and auditory attention. An ABA design was applied to analyze the effects of smartphone withdrawal. The first A refers to baseline measurements: Visual RT, Auditory RT, Go/No-Go RT and N-Back RT and Eriksen flanker RT. The B refers to 3 days of smartphone withdrawal, whereas the second A refers to the same measurements used in the baseline. In addition, several standardized scales were administered, among them: Smartphone addiction scale-short version (SAS-SV), Fear of missing out scale (FoMOs), Procrastination scale, and Psychological General Well-Being Index. One hundred and eleven participants took part in the study. Based on median split they were divided into two groups: high level and low level smartphone users. Moreover, thanks to an app installed on the participants’ smartphones, it was possible to measure levels of compliance with the task. Results indicate that participants with low levels of smartphone usage show less difficulty in their ability to wield the self-control needed to withdraw smartphone use and faster reaction times on cognitive tests than participants with high levels of smartphone usage. Moreover, the profile of participants with high levels of smartphone usage shows higher scores on the FoMOs and Procrastination scale, and lower scores in the Psychological General Well-Being Index. The results are discussed in light of self-regulation theory.

Introduction: Smartphone use has been related to health problems. Studies have indicated that the use of smartphones is associated with Sleep disturbances. However, little is known about the association between Smartphone addiction and sleep quality in Saudi Arabia.Objective: To determine the relationship between sleep quality and the use of a smartphone, specifically before sleep.Method: A cross-sectional study was conducted at four primary healthcare centers with a total of 205 patients participated in the study using a convenience sampling technique. The Pittsburgh Sleep Quality Index (PSQI) and Smartphone Addiction Scale – Short Version (SAS-SV) were used to measure association of Sleep Quality and Smartphone addiction.Results: Two-hundred-fiveparticipants enrolled in the study, of which 99 were female (51%) with a response rate of 84%. Mean age was 36 ±13 years for all participants. Mean PSQI scores were higher among females, single, frequent smartphone users, and unemployed sub- categories; thus, they indicated poorer sleep quality. There was also a significant negative association between age and PSQI scores t(193)= -2.45, p=0.015. Finally, there was a significant positive association between mean SAS-SV score and categorical global PSQI scores t(193)= 3.4, p=0.001.Conclusion: Our study showsahigh prevalence of smartphone addiction and poor sleep quality. Younger age, being single, heavy usage hours of smartphones, and high SAS-SV are significant factors associated with poorer sleep quality.

Over the past two decades, smartphones have become common, and the accompanying devices have also become much more popular and easily accessible worldwide. With the development of smartphones, accompanied by internet facilities, excessive smartphone use or smartphone addiction may cause sleep disturbance and daily dysfunction. This study proposed examining the association between personality traits and smartphone addiction and its effects on sleep disturbance. Four hundred and twenty-two university participants (80 male and 342 female participants) with a mean age of 20.22 years old were recruited in this study. All participants were asked to complete the following questionnaires: Smartphone Addiction Inventory (SPAI), Tri-dimensional personality questionnaire (TPQ), and Chinese Pittsburgh Sleep Questionnaire Index (CPSQI). The results showed that people with a high tendency toward novelty seeking (NS) as a personality trait, compared to those with lower tendency toward NS, are more likely to become addicted to smartphone use. Moreover, those with a stronger trait of being NS and specific impulsivity factor were found to have higher total scores in the SPAI (p < 0.05). In addition, linear regression analysis showed that the individuals with higher scores for withdrawal symptoms on the SPAI and anticipatory worry factor on the TPQ tended to have higher CPSQI total scores (p < 0.05). This information may be useful for prevention in individuals with personality traits making them vulnerable to smartphone addiction and for designing intervention programs to reduce intensive smartphone use and programs to increase capability in managing smartphone use.

Background: Excessive use of smartphones may be associated with behavioral and physical health changes and might cause musculoskeletal alterations in the head and neck region. Objective: To evaluate the prevalence of smartphone addiction in college students and its correlation with symptoms of head and neck pain and masticatory and trapezius muscle activity while resting, before and after smartphone use. Methods: Twenty university students participated in the study. They answered the Smartphone Addiction Scale and the Fonseca Anamnestic Index. Next, the participants were seated and prepared for electromyography through the placement of surface electrodes on the masseter, temporal, and trapezius muscles. Rest condition data were collected for 10 seconds before and after 30 minutes of smartphone use. Results: The results showed that 35% of the evaluated individuals were classified as smartphone addicted and 35% reported no head or neck pain in the previous 30 days. There was no association between smartphone use and head and neck pain. In the electromyography, there was an increase in RMS values after smartphone use in the right and left masseter muscles and the left trapezius. Conclusion: College students presented a high prevalence of smartphone addiction and head and neck pain, but these were not statistically associated. There was a change in muscle activity only in the right trapezius muscles before and after 30 minutes of smartphone use. These findings are contrary to the current belief that the use of smartphones correlates with pain in the neck region and changes in the electrical muscle activity, leading to fatigue in the cervical muscles.

Abstract Road surface roughness is considered as one of the most important aspect in functional condition of roads indicating to riding comfort in both transverse and longitudinal direction. For all highway projects maintaining proper surface evenness has been a mandatory requirement from the government of India. In this study, pavement unevenness was estimated using an android-based smartphone and system rely on the movement of a suspension system in response to the unevenness of the road surface travelled by a vehicle. Roughness index (RI) is an indicator to measure the standard road roughness. Conventional way of measuring RI involves usage of bump integrator, profilometer and roughometer. Present study proposes an alternative method to measure roughness using smartphones. The study was carried out in 2 different locations and 3 different smartphones to obtain the magnitude of deflections. Data collected using standard fifth wheel bump integrator is used for validation. Data collected through smartphone i.e., accelerometer sensor details was given as input to Fast Fourier transforms (FFT) to find the magnitude of deflection on the road. The results obtained from smartphones was then correlated with the existing roughness index data collected by standard fifth wheel bump integrator to establish an equation to predict RI using an android mobile.

BACKGROUND: The use of smartphones is increasing in the coronavirus disease (COVID-19) pandemic for various purposes, this encourages smartphone addiction. In addition, the incidence of insomnia has also increased in the pandemic era. AIM: This study was conducted to find an association between smartphone addiction and the incidence of insomnia, especially among students of the Faculty of Medicine, Udayana University. METHOD: This research is a descriptive-analytic study with the cross-sectional method, using two main questionnaires, Smartphone Addiction Scale-Short Version, and Insomnia Severity Index. Questionnaires were distributed using Google forms and then collected and analyzed using software SPSS version 25. RESULT: Overall the total research respondents with the inclusion criteria in this study amounted to 364 people. The results showed that 212 respondents (58.24%) had a high level of smartphone addiction and 152 respondents (41.76%) had a low level of smartphone addiction. In addition, 187 respondents (51.37%) experienced mild insomnia, 87 respondents (23.9%) experienced moderate insomnia, 13 respondents (3.57%) experienced severe insomnia, and 77 respondents (21.15%) did not experience insomnia. Based on the results of data analysis, it was found that smartphone addiction had a significant relationship (p = 0.002) with weak and positive correlation (r = 0.162) to the incidence of insomnia. CONCLUSION: It was found that the majority of respondents experienced high levels of smartphone addiction and mild insomnia. Another finding suggests the higher addiction to the smartphones, the more severe insomnia suffered.

Heart rate variability (HRV) provides essential health information such as the risks of heart attacks and mental disorders. However, inconvenience related to the accurate detection of HRV limits its potential applications. The ubiquitous use of smartphones makes them an excellent choice for regular and portable health monitoring. Following this trend, smartphone photoplethysmography (PPG) has recently garnered prominence; however, the lack of robustness has prevented both researchers and practitioners from embracing this technology. This study aimed to bridge the gap in the literature by developing a novel smartphone PPG quality index (SPQI) that can filter corrupted data. A total of 226 participants joined the study, and results from 1343 samples were used to validate the proposed sinusoidal function-based model. In both the correlation coefficient and Bland–Altman analyses, the agreement between HRV measurements generated by both the smartphone PPG and the reference electrocardiogram improved when data were filtered through the SPQI. Our results support not only the proposed approach but also the general value of using smartphone PPG in HRV analysis.

Since the first Android smartphones were released, many applications have been developed until today. One of them is security application. Security applications consist of several types of applications such as Antivirus, SIM Card Change Alarm, and Applocker. SIM Card Changed Alarm is a security application that has capability to monitor SIM Card change in Android smartphones. Although there are many SIM Card Change Alarm applications which are available in Google Playstore, there are many people who are not satisfied with this applications. It happens due to them only sends the SMS alert to the owner without locking the phone to prevent other people using it. The outcome of this research will have the same feature as SIM Card Change Alarm but with additional features such as locking the smartphone if the SIM Card has been changed, locking and unlocking remotely using SMS, triggering loud alarm, and calling-back to owner when the smartphone has been lost or stolen. The outcome expected for the Prifone Application is a userfriendly application which could be used by many people around the world and also is able to secure Android smartphones.

Full textAbstract:
Cette thèse étudie l’adoption de technologies dans les pays en développement. Dans le chapitre I, j’étudie l’adoption des smartphones en Inde. Les smartphones sont devenus le principal appareil grâce auquel les habitants des pays endéveloppement peuvent accéder aux avantages d’une numérisation généralisée. Cependant, la plupart des utilisateurs de téléphones mobiles dans les pays en développement continuent d’utiliser des téléphones basiques de faible qualité. Ce chapitre développe un modèle structurel de la demande des consommateurs et de l’offre des entreprises pour comprendre les principaux moteurs de l’adoption des smartphones. Je trouve que les gains en qualité des téléphones mobiles et les changements de revenus dans la population sont les principaux facteurs de la croissance des ventes de smartphones enInde. Compte tenu du rôle central du revenu dans l’adoption de cette technologie, je simule l’impact de subventions ciblées pour les smartphones. Je trouve que, comparées à des réductions d’impôts ad valorem ou à des subventions uniformes, les subventions ciblées sont les moins coûteuses pour le gouvernement et sont les plus efficaces pour la redistribution,étant (presque) entièrement appropriées par les consommateurs. Le chapitre II porte sur les services financiers numériques. L’utilisation des services financiers numériques dans les pays en développement peut être un outil d’inclusion financière, de lutte contre l’évasion fiscale et de facilitation de la prestation efficace des services publics. En utilisant un événement unique – un processus de démonétisation non annoncé et à grande échelle qui a eu lieu en 2016 en Inde et qui a augmenté les coûts à court terme de la détention d’espèces et de leurs transactions – ce chapitre étudie l’adoption d’une forme spécifique de SFN, à savoir les paiements mobiles, en Inde. Nous constatons que dans les régions où le marchédu travail était moins formel, et où les travailleurs étaient plus susceptibles d’être touchés par le processus de démonétisation, ce choc a conduit à une augmentation plus importante de l’utilisation de plateformes mobiles que dans les États où le marché du travail est plus formel. L’effet de cette “expérimentation forcée” fut cependant de courte durée. Au niveau individuel, les personnes les plus exposées au choc étaient plus susceptibles d’adopter les paiements mobiles et cet effet persiste au cours des deux années suivantes. Étonnamment, les effets marginaux du choc pour les femmes fortement exposées étaient presque deux fois plus élevés que pour les hommes fortement exposés. Dans le dernier chapitre de cette thèse, j’étudie (avec un co-auteur) l’adoption par les entreprises d’une nouvelle technologie dans leur menu de produits. En particulier, nous essayons de comprendre la valeur d’une technologie facilement imitable dans un contexte de marché émergent. Nous étudions l’introduction des portables double SIM sur le marché indien et quantifions la valeur de cette technologie pour les consommateurs. Nous quantifions également l’impact sur les résultats du marché de l’imitation rapide de cette technologie par des entreprises concurrentes. Nous constatons que l’introduction de cette technologie a entraîné une augmentation du surplus du consommateur de 3,1% à 8,9%, et une expansion de la taille totale du marché de 1,8% à 3,3%. Nous constatons également que si l’imitation réduit considérablement le profit de l’innovateur, elle rend également la technologie beaucoup plus abordable pour les consommateurs. Enfin, nous fournissons une borne inférieure du coût pour l’innovateur de la protection de la propriété intellectuelle dans un marché émergent. Nous constatons que cette borne inférieure atteint 12% des bénéfices observés de l’innovateurThis thesis studies technology adoption in an emerging market, taking the example of In-dia. In chapter I, I study the adoption of smartphones in India. Smartphones have becomethe primary device through which people in developing countries can access the benefitsof widespread digitization. However, most mobile phone users in developing countriescontinue to use low-quality feature phones. This chapter develops a structural model ofconsumer demand and supply to understand the main drivers of smartphone adoption. Itthen uses the estimates of the model to investigate how to best design pro-adoption poli-cies. I find that gains in device quality and changes in income distribution are the mainfactors behind the growth of smartphone sales in India. Given the central role of income indriving adoption, I simulate the impact of targeted subsidies for smartphones. I find that,compared to ad valorem tax reductions and uniform subsidies, targeted subsidies are theleast costly for the government and are the most effective for redistribution, being (almost)fully appropriated by consumers. Chapter II focuses on digital financial services. The useof digital financial services (DFS) in developing countries can be a tool for financial inclu-sion, curbing tax evasion, and facilitating the efficient delivery of public services. Using aunique event – an un-announced and large scale demonetization process that took place in2016 in India that increased the short-term costs of holding and transacting in cash, thischapter studies the uptake of a specific form of DFS, namely mobile payments, in India. Wefind that in states where the labour market was less formal, and where workers were morelikely to be affected by the demonetisation process, this shock led to a larger increase in theuse of platforms larger than in states where the labour market is more formal. The effectof this "forced experimentation" was, however, short lived. At the individual level, peoplewho were more exposed to the shock were more likely to adopt mobile payments and thiseffect persists over the next two years. Strikingly, the marginal effects of the shock for high-exposure women was almost twice as high as for high-exposure men. Our results contributeto understanding user behaviour and persistence of habits, with important implications forthe design of policies aimed at increasing the uptake of digital payment technologies. In thefinal chapter of this thesis, I (with a co-author) study firms’ adoption of a new technologyin their product portfolio. In particular, we attempt to understand the value of an easilyimitable technology in an emerging market context. We study the introduction of dual SIMhandsets in the Indian mobile phone market and quantify the value of this technology forconsumers. We also quantify the impact on market outcomes of the quick imitation of thistechnology by competing firms. We find that the introduction of dual SIM handsets led toan increase in the consumer surplus of 3.1% to 8.9%, and an expansion in the total sizeof the market by 1.8% to 3.3%. We also find that while imitation reduced the innovator’sprofit substantially, it also made the technology much more affordable. In the absence ofimitation, consumer prices would have been 22% higher. Finally, we provide a lower-boundon the innovator’s cost of protecting intellectual property in an emerging market. We findthis lower bound to be as high as 12% of the innovator’s observed profits ($ 29.5 million)

Full textAbstract:
Contexte : La tuberculose est la première cause de mortalité au monde et parmi les 10,4 millions de cas de tuberculose par année, 2,8 millions proviennent de l’Inde. De ce fait, il est considéré comme le pays ayant le plus haut taux d’incidence de la tuberculose au monde. Une manque de qualité des soins est une cause majeure pour l’épidémie de la tuberculose en Inde. Le secteur privé, qui n’est pas réglementé, prend soin de 50% des patients ayant la tuberculose. Des études précédentes indiquent le mauvais diagnostic ou le mauvais traitement comme des facteurs qui sont présents dans le secteur privé. Ce secteur comprend plusieurs types de médecins, dont ceux qui ont un diplôme en médecine et ceux qui n’ont pas de diplôme en médecine mais pratiquent la médicine. Une amélioration dans l’éducation des cliniciens utilisant les technologies mobiles, dont les applications mobiles, pourrait être une solution pour améliorer et assurer la qualité des soins des patients ayant la tuberculose. Toutefois, il existe peu d’études sur les technologies mobiles pour la tuberculose en Inde. Objectifs : Ce mémoire vise à évaluer l’expérience de l’usager et l’acceptabilité d’une application mobile (LearnTB) parmi les cliniciens académiques du secteur privé en Inde. Méthodes: L’étude a utilisé une approche à deux étapes. Cinq cliniciens (étape 1) et 101 cliniciens (étape 2) ont été contactés à Kasturba Hospital Manipal, Manipal, Inde entre février et mars 2017. L’expérience des participants était évaluée par le System Usability Scale. L’acceptabilité était évaluée par un questionnaire adopté du Technology Assessment Model. Les résultats étaient analysés à l’aide des statistiques descriptives, la régression linéaire multiple ainsi que la régression logistique. Résultats : Des taux de réponse de 100% et 99% ont été obtenus pour la première et deuxième partie respectivement. L’expérience de l’usager était vraiment positive. En ce qui concerne l’acceptabilité, une analyse de cheminement a confirmé la relation directe entre l’utilité perçue et l’intention d’utilisation, et la relation indirecte entre la facilité d’utilisation perçue et l’intention d’utilisation. La régression logistique a permis de cibler les items qui influencent fortement l’intention d’utilisation. Conclusion : L’expérience de l’usager pour LearnTB était vraiment positive, et l’utilité perçue a le plus grand impact sur l’intention d’utilisation (acceptabilité). Cette étude permet d’avoir une analyse préliminaire de l’acceptabilité des cliniciens concernant les technologies mobiles pour la tuberculose en Inde. D’autres recherches dans ce domaine sont requises afin d’assurer l’implantation optimale de ces technologies.Background: Tuberculosis (TB) is the leading infectious killer, and India accounts for 2.8 of the 10.4 million TB cases that occur each year, making it the highest TB burden country worldwide. Poor quality of TB care is a major driver of the epidemic in India. India’s large private, unregulated health sector manages over 50% of the TB patients, with studies showing suboptimal diagnosis and treatment in the private sector. This sector comprises of health professionals who are medically trained, and those who are not medically trained but are practicing medicine. Better education of doctors using mobile health (mHealth) applications is a possible solution. However, little is known about mHealth around TB in India. Objective: This masters thesis aimed to evaluate the user experience and acceptability of a smartphone application for TB (LearnTB) amongst private sector academic clinicians in India. Methods: This study adopted a two part approach. Five clinicians (part 1) and 101 clinicians (part 2) were contacted at Kasturba Hospital Manipal, Manipal, India between February and March 2017. The user experience of participants (part 1) was evaluated based on the System Usability Scale (SUS). Acceptability (part 2) was evaluated based on the Technology Acceptance Model (TAM). Data were analyzed using descriptive statistics, multiple linear regression as well as logistic regression analysis. Results: Response rates of 100% and 99% were achieved for part 1 and part 2, respectively. User experience was very positive. Regarding acceptability, a path analysis confirmed the direct relationship between perceived usefulness and intention to use, and the indirect relationship between perceived ease of use and intention to use. Logistic regression analysis helped target items strongly influencing intention to use. Conclusion: The user experience with LearnTB was very positive, and perceived usefulness has the highest impact on intention to use (acceptability). This study provides a preliminary analysis of mHealth interventions for TB in India, and emphasizes the need for future research in this domain.

Full textAbstract:
Patients with lower limbs problems are an increasing population in the US and many of them require surgery and its subsequent post-op Physical Therapy (PT). For all these patients, tracking their progress and evolution towards full recovery is very important. To assess the patients and track their progress, patients are usually required to perform very specific tests administered by a physical therapist. These tests either require very expensive equipment or rather require the subjective experience of the physical therapist who administer them. One of these tests is the Functional Gait Assessment (FGA) test, perhaps the most widely adopted one for gait assessment.
This thesis presents a system for Clinical Gait Assessment using exclusively the sensors embedded in today’s smartphones. The system processes the raw sensor data to perform the FGA test and calculate additional metrics, capable of identifying problems in the human gait. The system is therefore objective, as it is based on measurements; cheap, as it only requires a smartphone; mobile, as it can be used pretty much anywhere; and self-care, as it does not need the presence of a physical therapist.
The system was designed and tested on the Android OS with the phone attached to the back of the user using a belt or elastic band. It includes a new step detection algorithm with a mean absolute error of ±1 and algorithms to detect the deviation from a straight path with an accuracy of 90%, 80%, 35%, and 30% for each of the required deviation levels of the FGA test. Additionally, the system includes autocorrelation and DTW metrics, which provide additional information to detect different impediments of the user gait.

How do young adult students communicate through their smartphones today? Which applications and features do they choose? What motivates their choices for the various possible situations? In this paper we investigate which communication channels young adult students in Sweden use for private message communication in their smartphones, in what way they use the channels and why they choose specific channels for different types of communication. In Sweden today, there are numerous of different ways of communicate through smartphones. We have interviewed ten Swedish young adult students regarding their use. The results speaks for that SMS has proven to still be used very frequently, even though it has existed for many years and that there are plenty of other ways to communicate through private messages today. Social media, primarily Facebook, also attracts users to communicate through private messages with their smartphones. SMS isn’t any longer the obvious method for sending a message. By presenting the result of our study, we hope to provide for future design resolutions and to give the next generation of smartphones communication tools that are as optimal as possible.

Full textAbstract:
Sociala medier har de senaste åren expanderat med en enorm kraft. Facebook som startades år 2004 är idag världens största sociala media och har i dagsläget över 500 miljoner användare. Om ökningen av användare fortsätter som den gjorde under år 2010 så kommer det år 2012 finnas fler Facebookanvändare än det finns invånare i Europa. Detta gör att det känns oerhört intressant och relevant för oss som medie- och kommuni-kationsvetare att undersöka området. Syftet med uppsatsen är att med hjälp av aktiva samtal i fokusgrupper undersöka användningen av sociala medier via den nya tidens mobiltelefoner (smartphones). Detta är viktigt att studera på grund av att fenomenet sociala medier har blivit en viktig del för oss medie- och kommunikationsvetare och kommer vara en stor del i kommunikationsbran-schens framtid. Vi har använt oss av aktiva fokusgruppssamtal för att få fram svar på våra frågeställningar. Fokusgrupperna genererade ett tydligt resultat som visade att användarna ser den ökade tillgängligheten som den största faktorn till förändringen i deras användning. Dessutom har tillgängligheten skapat ett ständigt pågående samtal på de sociala medierna som tidigare inte fanns där. Den ökade användningen har även medfört ett behov att hålla sig uppdaterad på de sociala medierna.

This c-level essay examines how deaf and hearing impaired individuals use smartphones to live and communicate in a “hearing world”. The main target is to find some understanding of the struggles of this population and smartphones have made it easier to adapt to the hearing worlds’ demands with the applications that follow. To acquire the information for this essay, representatives from both the deaf and hearing impaired communities were interviewed. The findings of this qualitative study show that there are many applications that have advantages to aid the lives of deaf and hearing impaired. These include WhatsApp, Tango and many others. All of the respondents appreciated the new technology but also said that there is work to be done in that area. Especially the poor quality of the video calls is not satisfactory to the users using sign language.

Thesis, Umeå universitet, Sociologiska institutionen, 2019. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-163161.
Full textAbstract:
This thesis presents studies and results for three questions regarding young women and their usage of smartphones related to their self-presentation and personal sphere in public spaces. Six young females signed up to participate after they were asked to be without their smartphone for approximately two hours in public spaces. The reason why we thought this would be beneficial was since this would give the participants the chance to reflect on their normal usage whilst in public. The participants were later, in the interview, questioned about their overall experience and were asked questions considering the different themes of the study. The results of the study show that the functions most used in a smartphone are communication and music. Results for self-presentation show that smartphones play a major part in young females lives and they use their smartphone in order to present themselves in a certain way. It was acknowledged that some individuals find it important to present themselves as not being lonely, and to achieve this they use their smartphone in order to seem like they are interacting with someone even in situations when they are not. Lastly results of the third theme show that young females use their smartphones in different ways in order to protect their personal sphere, by for example listening to music, holding their phone visible or by calling someone.

Thesis, Umeå universitet, Institutionen för socialt arbete, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-156226.
Full textAbstract:
Detta är en studie som undersöker hur yrkesverksamma behandlare i Västerbottens län ser på återfall och få deras uppfattning om hur det kommer sig att en del alkoholmissbrukare inte återfaller. Hur en före detta missbrukare motiveras till att inte ta ett återfall är ett komplext område som inbegriper många delområden. Dessa områden kan bestå av såväl interna och, eller, externa faktorer. För att få en inblick i problematiken har semistrukturerade kvalitativa intervjuer genomförts med professionella behandlare. Den empiri intervjuerna har försett arbetet med har kopplats samman och kritiserats utifrån vetenskaplig litteratur. Studien har fokus på tre delområden. Dessa är huruvida det går att digitalisera behandlingsvård alternativt eftervård, om det finns några skillnader mellan behandling och återfall mellan män och kvinnor och ifall det skiljer sig mellan behandlares syn på återfall och den vetenskapliga litteraturens syn på återfall. Slutsatserna i studien belyser bland annat att digitalisering av vård kan ha positiva effekter när det kommer till tillgängligheten och medverkande på distans, men att det finns situationer då behandling kräver fysisk närvaro för att uppnå bästa resultat. Vidare visar den vetenskapliga litteraturen och de aktuella intervjupersonerna på olika upplevelser vad gäller könets betydelse i relation till återfallsprevention. En slutsats som tagits fram är att det skiljer lika mycket mellan de individer som har samma kön som det skiljer mellan individer som har olika kön, vilket betyder att behandlingen bör vara individanpassad. Samtlig datainsamling, såväl från intervjupersoner och vetenskaplig litteratur, är överens om att det är individen som med sitt självbestämmande väljer att ta ett återfall. Det betyder att individen tar ett återfall och får därmed inte ett återfall utan att själv ha agerat.

Full textAbstract:
In a large number of electronic devices, users interact with the system by navigating through various menus. Auditory menus can complement or even replace visual menus, so research on auditory menus has recently increased with mobile devices as well as desktop computers. Despite the potential importance of auditory displays on touch screen devices, little research has been attempted to enhance the effectiveness of auditory menus for those devices. In the present study, I investigated how advanced auditory cues enhance auditory menu navigation on a touch screen smartphone, especially for new input gestures such as tapping, wheeling, and flicking methods for navigating a one-dimensional menu. Moreover, I examined if advanced auditory cues improve user experience, not only for visuals-off situations, but also for visuals-on contexts. To this end, I used a novel auditory menu enhancement called a "spindex" (i.e., speech index), in which brief audio cues inform the users of where they are in a long menu. In this study, each item in a menu was preceded by a sound based on the item's initial letter. One hundred and twenty two undergraduates navigated through an alphabetized list of 150 song titles. The study was a split-plot design with manipulated auditory cue type (text-to-speech (TTS) alone vs. TTS plus spindex), visual mode (on vs. off), and input gesture style (tapping, wheeling, and flicking). Target search time and subjective workload for the TTS + spindex were lower than those of the TTS alone in all input gesture types regardless of visual type. Also, on subjective ratings scales, participants rated the TTS + spindex condition higher than the plain TTS on being 'effective' and 'functionally helpful'. The interaction between input methods and output modes (i.e., auditory cue types) and its effects on navigation behaviors was also analyzed based on the two-stage navigation strategy model used in auditory menus. Results were discussed in analogy with visual search theory and in terms of practical applications of spindex cues.

Full textAbstract:
ZusammenfassungWie wird Gesundheit in eine messbare Größe verwandelt? Basierend auf empirischen Untersuchungen werden wir die Quantifizierung von Gesundheit in zwei verschiedenen Bereichen analysieren: Diet- und Mood-Tracking. Aus der Perspektive der Ökonomie der Konventionen (Économie des Conventions, EC) betrachtet, investieren SelbstvermesserInnen hier in neue Formen und Messungen der Äquivalenz, wobei sich ihnen drei bedeutende Hindernisse stellen: die Ungenauigkeit des Messens, die sperrige Materialität von Objekten und alltäglichen Praktiken sowie das unscharfe Verhältnis von alltäglichem Tun und Quantifizierung. Einerseits streben SelbstvermesserInnen nach der Herstellung eines praktischen Konsenses, wie eine „genaue“ Messung aussehen sollte bzw. in welchen Fällen Ungenauigkeiten nicht toleriert werden können. Auf der anderen Seite stützen sich SelbstvermesserInnen auf je feldspezifische Kriterien für eine angemessene Genauigkeit, je nachdem, wie sie ihre Vermessungspraktiken in den Alltag integrieren. In der EC kommt Objekten konzeptionell eine zentrale Rolle zu, indem sie kompetente Alltagsakteure bei ihren Koordinationsbemühungen sowie bei der Bewältigung normativer und ethischer Fragen unterstützen. Wir schlagen eine Sichtweise vor, in der Technologien wie Sensoren, mHealth-Anwendungen und Smartphones als intermediäre Objekte in variierenden Engagements und Aushandlungsprozessen in den Alltag des Selbstvermessens eingebunden werden. In beiden genannten Feldern der Selbstvermessung entsteht so eine ganz eigene Konfiguration von Messungen, Objekten, Widerständen und Engagements, welche die gegenwärtigen Konventionen von Gesundheit schwer fassbar und fragmentiert und damit für Gesundheitsorganisationen, politische EntscheidungsträgerInnen und NutzerInnen gleichermaßen unverfügbar machen.

Full textAbstract:
This chapter traces the meaning of “the swipe.” The verb “to swipe” has many colloquial meaning. In recent years, it has come to mean running a charge card through a digital reader or using an index finger to manipulate the touch screen of a smartphone. As smartphones become payment instruments, these two meanings have been united. The chapter explores the so-called “swipe fee wars,” being fought between banks, retailers, and phone companies to determine who will bear the cost of payment. As the business models move away from fees and towards extracting the value “big data,” a related battle is being waged over access to transactional data.

Full textAbstract:
Humans spend on average more than half of their day sitting down. The ill-effects of poor sitting posture and prolonged sitting on physical and mental health have been extensively studied, and solutions for curbing this sedentary epidemic have received special attention in recent years. With the recent advances in sensing technologies and Artificial Intelligence (AI), sitting posture monitoring and correction is one of the key problems to address for enhancing human well-being using AI. We present the application of a sitting posture training smart cushion called LifeChair that combines a novel pressure sensing technology, a smartphone app interface and machine learning (ML) for real-time sitting posture recognition and seated stretching guidance. We present our experimental design for sitting posture and stretch pose data collection using our posture training system. We achieved an accuracy of 98.93% in detecting more than 13 different sitting postures using a fast and robust supervised learning algorithm. We also establish the importance of taking into account the divergence in user body mass index in posture monitoring. Additionally, we present the first ML-based human stretch pose recognition system for pressure sensor data and show its performance in classifying six common chair-bound stretches.

Automated-Entry Patient-Generated Health Data for Chronic Conditions: The Evidence on Health Outcomes. Agency for Healthcare Research and Quality (AHRQ), March 2021. http://dx.doi.org/10.23970/ahrqepctb38.
Full textAbstract:
Background. Automated-entry consumer devices that collect and transmit patient-generated health data (PGHD) are being evaluated as potential tools to aid in the management of chronic diseases. The need exists to evaluate the evidence regarding consumer PGHD technologies, particularly for devices that have not gone through Food and Drug Administration evaluation. Purpose. To summarize the research related to automated-entry consumer health technologies that provide PGHD for the prevention or management of 11 chronic diseases. Methods. The project scope was determined through discussions with Key Informants. We searched MEDLINE and EMBASE (via EMBASE.com), In-Process MEDLINE and PubMed unique content (via PubMed.gov), and the Cochrane Database of Systematic Reviews for systematic reviews or controlled trials. We also searched ClinicalTrials.gov for ongoing studies. We assessed risk of bias and extracted data on health outcomes, surrogate outcomes, usability, sustainability, cost-effectiveness outcomes (quantifying the tradeoffs between health effects and cost), process outcomes, and other characteristics related to PGHD technologies. For isolated effects on health outcomes, we classified the results in one of four categories: (1) likely no effect, (2) unclear, (3) possible positive effect, or (4) likely positive effect. When we categorized the data as “unclear” based solely on health outcomes, we then examined and classified surrogate outcomes for that particular clinical condition. Findings. We identified 114 unique studies that met inclusion criteria. The largest number of studies addressed patients with hypertension (51 studies) and obesity (43 studies). Eighty-four trials used a single PGHD device, 23 used 2 PGHD devices, and the other 7 used 3 or more PGHD devices. Pedometers, blood pressure (BP) monitors, and scales were commonly used in the same studies. Overall, we found a “possible positive effect” of PGHD interventions on health outcomes for coronary artery disease, heart failure, and asthma. For obesity, we rated the health outcomes as unclear, and the surrogate outcomes (body mass index/weight) as likely no effect. For hypertension, we rated the health outcomes as unclear, and the surrogate outcomes (systolic BP/diastolic BP) as possible positive effect. For cardiac arrhythmias or conduction abnormalities we rated the health outcomes as unclear and the surrogate outcome (time to arrhythmia detection) as likely positive effect. The findings were “unclear” regarding PGHD interventions for diabetes prevention, sleep apnea, stroke, Parkinson’s disease, and chronic obstructive pulmonary disease. Most studies did not report harms related to PGHD interventions; the relatively few harms reported were minor and transient, with event rates usually comparable to harms in the control groups. Few studies reported cost-effectiveness analyses, and only for PGHD interventions for hypertension, coronary artery disease, and chronic obstructive pulmonary disease; the findings were variable across different chronic conditions and devices. Patient adherence to PGHD interventions was highly variable across studies, but patient acceptance/satisfaction and usability was generally fair to good. However, device engineers independently evaluated consumer wearable and handheld BP monitors and considered the user experience to be poor, while their assessment of smartphone-based electrocardiogram monitors found the user experience to be good. Student volunteers involved in device usability testing of the Weight Watchers Online app found it well-designed and relatively easy to use. Implications. Multiple randomized controlled trials (RCTs) have evaluated some PGHD technologies (e.g., pedometers, scales, BP monitors), particularly for obesity and hypertension, but health outcomes were generally underreported. We found evidence suggesting a possible positive effect of PGHD interventions on health outcomes for four chronic conditions. Lack of reporting of health outcomes and insufficient statistical power to assess these outcomes were the main reasons for “unclear” ratings. The majority of studies on PGHD technologies still focus on non-health-related outcomes. Future RCTs should focus on measurement of health outcomes. Furthermore, future RCTs should be designed to isolate the effect of the PGHD intervention from other components in a multicomponent intervention.
