Abstract:

Introduction: The current work probes the effectiveness of multimodal touch screen tablet electronic devices in conveying science, technology, engineering, and mathematics graphics via vibrations and sounds to individuals who are visually impaired (i.e., blind or low vision) and compares it with similar graphics presented in an embossed format. Method: A volunteer sample of 22 participants who are visually impaired, selected from a summer camp and local schools for blind students, were recruited for the current study. Participants were first briefly (∼30 min) trained on how to explore graphics via a multimodal touch screen tablet. They then explored six graphic types (number line, table, pie chart, bar chart, line graph, and map) displayed via embossed paper and tablet. Participants answered three content questions per graphic type following exploration. Results: Participants were only 6% more accurate when answering questions regarding an embossed graphic as opposed to a tablet graphic. A paired-samples t test indicated that this difference was not significant, t(14) = 1.91, p = .07. Follow-up analyses indicated that presentation medium did not interact with graphic type, F(5, 50) = 0.43, p = .83, nor visual ability, F(1, 13) = 0.00, p = .96. Discussion: The findings demonstrate that multimodal touch screen tablets may be comparable to embossed graphics in conveying iconographic science and mathematics content to individuals with visual impairments, regardless of the severity of impairment. The relative equivalence in response accuracy between mediums was unexpected, given that most students who participated were braille readers and had experience reading embossed graphics, whereas they were introduced to the tablet the day of testing. Implications for practitioners: This work illustrates that multimodal touch screen tablets may be an effective option for general education teachers or teachers of students with visual impairments to use in their educational practices. Currently, preparation of accessible graphics is time consuming and requires significant preparation, but such tablets provide solutions for offering “real-time” displays of these graphics for presentation in class.

Abstract:

We designed a computer pencil and tablet for Freestyle,TM a multimedia communications system based on handwritten annotations. Although graphics pens and tablets are already in use for handprinted character recognition and CAD applications, designing a pen and tablet specifically for rapid, continuous handwriting required substantial changes. Design criteria came from a laboratory study in which evaluators performed various writing and drawing tasks with a working pen and tablet. Evaluators rated the working system, plus model pens and tablets that were variants on a proposed design. Field observations of working prototypes also contributed to the final product.

Abstract:

From a strategic 1962 article cataloging the imprints on tablets, capsules and softgels, the art of identification of solid medication dosage form has proceeded to where all prescription medications, including controlled substance, over-the-counter (OTC) drugs, veterinary and homeopathic drug products must be imprinted. Imprints may be comprised of logos, numerical and/or alphabetical information. Imprints are electronically searchable by two computer programs, one of which provides graphics of logos. The public and health, law enforcement and teaching professionals have a need to know when a "stray" tablet or capsule is found what it is with a high degree of accuracy. Imprints may soon be on prescription labels and searchable through various websites on the internet.

Abstract:

The development of digital technologies leads to a variety of pictorial arts. With the advent of computer technology and communication technologies, areas such as computer graphics, computer and digital design, and phenomena such as digital art have emerged. The article analyzes these concepts, which provided an opportunity for further study. Based on the analysis of Internet resources on digital art, the following main trends are identified: virtual art, 3D printing, open source software, art of artificial intelligence, a combination of 2D animation and modern technologies, 3D painting, UX / UI design, game design, concept art and character design. Examples of reflection these tendencies in modern art are given. Given the selected trends, it is shown how they affect the content of training in computer graphics and digital design for students of the educational program "Digital Design" (list of compulsory and optional educational components, the content of educational practice). It is noted that to successfully work with computer graphics, students need to master traditional knowledge of pictorial arts (the concept of composition, color, perspective, proportions, shadows) and the ability to use them to create digital products using computer programs (2D graphic editors and 3D graphics) and digital technology (graphics tablet, personal and personal computer, projection equipment, camera, devices for VR and AR reality, scanner and printer, including 3D scanner and 3D printer).

Abstract:

The article presents the possibility of using a graphics tablet to control an industrial robot. The paper presents elements of software development for offline and online control of a robot. The program for the graphic tablet and the operator interface was developed in C# language in Visual Studio environment, while the program controlling the industrial robot was developed in RAPID language in the RobotStudio environment. Thanks to the development of a digital twin of the real robotic workstation, tests were carried out on the correct functioning of the application in offline mode (without using the real robot). The obtained results were verified in online mode (on a real production station). The developed computer programmes have a modular structure, which makes it possible to easily adapt them to one’s needs. The application allows for changing the parameters of the robot and the parameters of the path drawing. Tests were carried out on the influence of the sampling frequency and the tool diameter on the quality of the reconstructed trajectory of the industrial robot. The results confirmed the correctness of the application. Thanks to the new method of robot programming, it is possible to quickly modify the path by the operator, without the knowledge of robot programming languages. Further research will focus on analyzing the influence of screen resolution and layout scale on the accuracy of trajectory generation.

Abstract:

Given the proliferation of touch-sensitive screen technologies, the factors contributing to efficiency of cursor control device were examined to better inform choice and design of Graphical User Interfaces. Fitts' law can be used to describe the relative efficiency of these cursor control devices. Experiment One required 18 participants to move a cursor between targets depicted upon a WACOM PL400 display graphics tablet, over various amplitudes, using a computer mouse or stylus, examining the speed and accuracy of cursor placement. The touch sensitive screen allowed faster acquisition of targets than the mouse. Since the mouse has a higher control/display ratio (gain) than the touch sensitive screen, Experiment Two addressed manipulation of the gain settings on computer mouse performance. Low gain offered some accuracy benefits. Possible posture problems associated with the touch sensitive screen were explored in Experiment Three. Screen orientation had little effect upon cursor positioning performance, suggesting the benefits of the touch sensitive screen can be transferred to user-friendly postures.

Abstract:

As the construction industry advances technologically, it becomes imperative to introduce the respective information technology tools to present-day curriculum. This research study was conducted to identify any significant differences in student performance contributed by using an information technology tool, specifically the Apple® iPad® tablet. IPad tablets were used to electronically present construction drawings to a treatment group, and a control group was given traditional paper drawings. Following an instructional lecture, students were given a test based on the provided construction drawings. The test results indicate that there was no significant difference in performance between students who used the information technology tool to complete the test and those who used traditional paper drawings to complete the same test. The treatment group also answered a usability survey, which helped to comprehend how students perceive the tablet’s usability. Students indicated that they would like to use the tool in the future.

Abstract:

Introduction The authors examined a tablet computer application (iPad app) for its effectiveness in helping students studying pre-algebra to solve mathematical word problems. Methods Forty-three visually impaired students (that is, those who are blind or have low vision) completed eight alternating mathematics units presented using their traditional literacy medium or an iPad app. Twenty percent of the mathematics problems included graphics such as maps, line graphs, and bar graphs. During each session, teachers of visually impaired students rated the amount of support they provided for students and the student motivation. Results Students answered more mathematics problems correctly when using the iPad app and, overall, teachers reported that their students were more motivated with the app than with their traditional literacy medium. Students often used the hints provided in the app when they did not solve a problem correctly the first time. Discussion Visually impaired students and their teachers found the app and graphics to be easy to use and motivating. The built-in Scratch pad was used by almost all students who were print users. Implications for practitioners The study results contribute to the growing body of knowledge about the potential value of tablet-type devices for use by visually impaired students.

Abstract:

Introducción: este trabajo examina la efectividad de los dispositivos electrónicos de tableta multimodales con pantalla táctil para transmitir gráficos de ciencia, tecnología, ingeniería y matemáticas (CTIM) a través de vibraciones y sonidos a personas con discapacidad visual (es decir, con ceguera o con baja visión), y establece una comparación con gráficos en relieve similares presentados en un formato impreso. Método: se obtuvo la participación en el estudio de una muestra de 22 voluntarios con discapacidad visual seleccionados en un campamento de verano y en escuelas locales para estudiantes ciegos. En primer lugar, se enseñó a los participantes, en un breve periodo (~30 minutos), a explorar gráficos mediante una tableta con pantalla táctil multimodal. A continuación, los participantes examinaron seis tipos de gráficos en relieve (línea numérica, tabla, gráfico circular, gráfico de barras, gráfico de coordenadas y plano) presentados en una tableta y en papel impreso. Tras la exploración, los participantes respondieron a tres preguntas por cada tipo de gráfico relativas a su contenido. Resultados: la precisión de los participantes solo se mostró un 6 % más alta al responder a preguntas relativas a un gráfico impreso en relieve frente al mismo gráfico mostrado en una tableta. Una prueba t para muestras emparejadas mostró que esta diferencia no era significativa: t(14) = 1,91, p = 0,07. Los análisis de seguimiento no revelaron interacciones entre el medio de presentación y el tipo de gráfico: F(5, 50) = 0,43, p = 0,83, o la capacidad visual, F(1, 13) = 0,00, p = 0,96. Análisis: los resultados demuestran que las tabletas táctiles multimodales son comparables a los gráficos impresos en relieve a la hora de transmitir contenidos iconográficos de carácter científico y matemático a personas con discapacidades visuales, independientemente de la gravedad de las mismas. La relativa equivalencia en la precisión de la respuesta utilizando los distintos medios (tableta o papel) resultó inesperada, ya que la mayoría de los alumnos participantes eran lectores de braille y tenían experiencia en el manejo de gráficos en relieve, mientras que entraron en contacto con la tableta por primera vez en el mismo día en el que se efectuó la prueba. Implicaciones para los profesionales: el presente trabajo muestra que las tabletas multimodales con pantalla táctil pueden ser una opción eficaz de la que pueden hacer uso en el curso de su actividad docente los profesores de educación general o aquellos profesores que tengan alumnos con discapacidad visual. En la actualidad, la creación de gráficos accesibles exige mucho tiempo y una preparación notable, pero estas tabletas aportan soluciones que permiten ofrecer visualizaciones de gráficos en tiempo real para su presentación en clase.

Abstract:

Abstract. The problem discussed in this research is connected with the functionality of the graphical user interface (GUI) of global web mapping services displayed on different devices. Displaying a mapping service on devices with diverse display screen size causes the adaptation of the graphical user interface to the size of the screen. This adaptation is the result of the responsive design technique which enables one to display the same web content on different devices. Eight global web mapping services: Google Maps, Bing Maps, OpenStreetMap (OSM), Baidu Maps, Yandex Maps, 2GIS, MapQuest, and HERE WeGo, constituted the source of the data. All of them were displayed on four display screens: the monitor of a personal computer, laptop, tablet, and smartphone in order to compare the similarities in the adaptation of GUI, its functions and map content.The aim of the research conducted was to find different solutions for displaying GUI of the same mapping service on diverse display screens of various devices and to track which functions are the most common and how they differ in terms of graphics.Methodology of the research is based on the comparative analysis of eight global web mapping services in terms of the number of GUI buttons, their layout, graphic style, the map functionality, and map content displayed on four devices of different display screen size.The results showed that most of the global web mapping services adapt to the device and their way of use. Some of them are also responsive in the context of external conditions. Interestingly, the adaptation between the PC monitor, laptop and tablet occurs only by changing the size of GUI buttons, other functions remaining the same. Only in the case of smartphones GUI adapts to the size of the device, the number of buttons decreases and their layout changes, new functionality is available (e.g. day/night mode), and the map content is more generalized. On that basis, authors concluded that GUI of global map services constituted a good example of responsive web design.

Abstract:

Creativity is closely linked to 21st century competencies. For students in secondary education, it is important to maintain and encourage creativity as part of fine arts classes. This can be achieved through meaningful integration of information and communication technology, as this allows students to express themselves in a more engaging and in-depth way. To help empower class teachers, this research presents a successful example of good practice. Courses are planned in several stages, starting from goals of the subject in relation to digital competencies. The app for the tablet and the digital pen is selected according to the criteria of quality, simplicity of use and relevance. Technology is included in the lessons with the goal to achieve a significant upgrade of the learning experience. Students evaluate their artistic expression as positive and successful. With this activity, students develop their creative and artistic expression abilities to the greatest extent. Their graphic products meet the art task and are aesthetically perfective for their age. The expressive elements within the computer graphics are originally rhythmically arranged. Keywords: digital pen, example of good teaching, fine arts, innovative pedagogy, lesson planning

Abstract:

To better distinguish between traced and freehand signature simulations, 12 participants practiced upon a WACOM SD420 graphics tablet tracing a historical signature at Slow or Very Slow speeds, with a subsequent comparison of freehand and traced signature simulations. Kinematic analyses focused upon stroke efficiency and pressure, while computer algorithms determined variability of simulations around an original. Traced simulations had reduced spatial variability after practice. Very Slow simulations were more dysfluent, had greater spatial error and employed more pressure. Pen pressures varied more with speed during freehand reproductions. Writing speed was an important contributor to line quality and spatial correspondence during signature simulation. Purchase Article _ $10

Abstract:

Abstract A major barrier to reducing Elder Mistreatment (EM) is an inability to accurately identify victims. We conducted a qualitative study to evaluate stakeholders’ perceived value and likelihood of adopting a tablet-based digital health tool to facilitate screening and prompt self-disclosure of EM in emergency departments (ED). The interactive tool utilizes virtual coaching, interactive multimedia libraries (graphics, animations, etc.), electronic screening, and brief motivational interviewing designed to enhance identifying EM among older adults. We conducted 3 focus groups with stakeholders, including 24 adults 60+ years, 2 social workers, 2 caregivers, and 2 ED clinicians. Two focus groups included only older adults, while one included representatives of all stakeholders. The main findings include: using a female voice for the tool narrator, larger font size, more multimedia, and headphones for privacy; and making a person available during screening if assistance is needed. Stakeholders indicated that it is difficult for victims to ask for help and any type of mistreatment screening would be helpful. On a 7-point Likert scale ranging from “1=Very Comfortable” to “ 7=Very Uncomfortable”, older adults scored 2.8 on average for whether they would feel comfortable using a tablet to screen for EM. Some said digital screening would maintain privacy and anonymity. Stakeholders highlighted the need to explain community resources available to older adults once EM is disclosed, especially resources offering help to the caregiver. In summary, this qualitative study supported using tablet-based screening for EM and highlighted the need to target stigma related to EM disclosure and fear of retaliation.

Abstract:

Two inscriptions from Bosnia and Herzegovina (from the vicinities of Livno and Ljubuški) and a group of graffiti from the Bregalnica river basin in the eastern part of North Macedonia are examined in this paper. It has been suggested by previous scholars that all of these inscriptions contain Glagolitic letters. The first part of the paper offers grammatical analysis and a new translation of the inscription on the tomb of a priest named Těhodrag. The tomb was unearthed in 2003 around Livno, 50 km northeast of Split. In the second section the author examines the graphics of the donor inscription on the Humac tablet from the vicinity of Ljubuški, 30 km southwest of Mostar, and proposes a revised reading of the text. The third part offers an interpretation of enigmatic signs on stones from the Bregalnica river basin, northeast of Štip. The author comes to the conclusion that none of the examined epigraphic sources contain Glagolitic letters. Both inscriptions from Bosnia and Herzegovina are in Cyrillic with some letters written in mirror image. The letter «есть» is turned 180 degrees in both graffiti, and there is one mirror «вѣдѣ» and two mirror «нашь» at the end of the inscription on the Humac tablet. The abundance of mirror-image letters probably stems from the unique shape of the Humac inscription itself: its tiered lines go around the fours sides of the tablet, forming something like a squared spiral. As for the supposedly «Glagolitic» signs on stones from the Bregalnica river basin, closer study reveals that they are tamgas, most likely carved by bearers of the Turkic cultural tradition, the Bulgars.

Abstract:

Although a small island 2 km off the southern coast of Turkey, Dana Island offers a rich history which is likely to shed light upon the Dark Ages. Starting from 2015 our archaeological team discovered through continuing coastal and underwater excavations 274 shipsheds/slipways there. This discovery places Dana Island among the biggest shipyards of antiquity. The slipways varied in dimensions suitable for vessels of different sizes from small boats to large warships. Historical sources suggest that the name of the island may stem from Yadnana, Yadana or Adana which was mentioned in an Assyrian tablet of the 8th century BC, as an island in the vicinity of Cyprus. Archaeological evidence exists that shows Dana Island had played a significant role in seamanship activities in Levant starting from Neolithic times. A substantial part of the naval campaigns must have involved Dana Island which used be the biggest shipyard/naval base of the Eastern Mediterranean. A 3D model of the island has been made by using photogrammetry and computer graphics methods and simulations were executed to check the hypotheses related to the involvement of Dana Island in the major sea battles of antiquity, such as Sea Battle of Lade in 495 BC.

Abstract:

This paper presents the results of an exploratory study in which the authors investigated the impact of tangible interface used by children at the elementary school level. Exploration of the viability of graphics tablet and the pen tool was conducted by investigating the children's ease in acclimating to the technology and the effectiveness in engaging them to complete some tasks. Several children were invited to a workshop where they learned and played BatiKids, a game-based learning developed to support children in learning the process of making Indonesian hand-written batik. The qualitative analysis based on the notes and video recording taken on the field observational, and the responses to interview questions to the participants. The results show the main findings and discuss the design implications for a tangible interface in the context of BatiKids.

Abstract:

Nowadays, an important research effort in healthcare biometrics is finding accurate biomarkers that allow developing medical-decision support tools. These tools help to detect and supervise illnesses like Parkinson’s disease (PD). This paper contributes to this effort by analyzing a convolutional neural network (CNN) for PD detection from drawing movements. This CNN includes two parts: feature extraction (convolutional layers) and classification (fully connected layers). The inputs to the CNN are the module of the Fast Fourier’s transform in the range of frequencies between 0 Hz and 25 Hz. We analyzed the discrimination capability of different directions during drawing movements obtaining the best results for X and Y directions. This analysis was performed using a public dataset: Parkinson Disease Spiral Drawings Using Digitized Graphics Tablet dataset. The best results obtained in this work showed an accuracy of 96.5%, a F1-score of 97.7%, and an area under the curve of 99.2%.

Abstract:

Disabilities of the articulations of the head and cervical spine can often be detected only by exact measurement of functional radiographs. From two radiographs, one in flexion and one in extension, not only can the total mobility of the head be measured, but also the mobility of the individual articulations can be evaluated by taking exact measurements of the position of each vertebra. A method for semi-automatic measuring of such pairs of radiographs is presented. Edges and structures of the bones that are clearly visible in both radiographs are digitized on a graphics tablet. Then, by computer program, each vertebra of the first radiograph is shifted and rotated until it fits best to the respective vertebra of the second radiograph. Thus, for each articulation, the mobility angle and the location of the mobility axis relative to the adjacent vertebra, can be computed. First experiences with this method are presented.

Abstract:

This study investigated the effects of five body orientations (supine, kneeling, sitting, standing, and prone) on perception of spatial auditory and spatial tactile cues along eight equidistant points (45° separation) of the azimuth, using a within-participant design. Participants (N = 30) used a graphics tablet and stylus to indicate the perceived direction indicated by either vibrotactile stimuli applied to the abdomen, or spatial auditory stimuli presented via headphones. Response time data show responses to spatial tactile cues were significantly faster than spatial auditory cues at each body position and for each point along the azimuth, with no significant effects of body orientation. Absolute angle differences between presented and perceived cues were significantly smaller in the tactile condition for five of the eight stimulus positions, with no significant effects of body orientation. Results are discussed in terms of designing multi-sensory directional cues for reducing visual search space for dismounted soldiers

Abstract:

The sartorius muscle of Rana esculenta was fixed and dehydrated by different methods and cross-sections of sarcomeres of different lengths were examined by electron microscopy. The area within the outlines of the thin filaments in negatives was measured using a high-resolution television system and a graphics tablet or by using a microdensitometer and computer processing the images with a density threshold above the background level. In all specimens the area of the thin filaments in the I-bands was found to be larger than in the S-zones of the A-bands where the thick and thin filaments interpenetrate. The difference was statistically significant and independent of the length of the sarcomere. The results are in agreement with previous observations in glycerol-extracted fibres. It is suggested that the change in size of the thin filaments might be accounted for by some interaction with the thick filaments.

Abstract:

Document image segmentation is an important research area of document image analysis which classifies the contents of a document image into a set of text and non-text classes. Previous existing methods are often designed to classify text and halftone therefore they perform poorly in classifying graphics, tables and circuit, etc. In this paper, we present a robust multi-level classification method using multi-layer perceptron (MLP) and support vector machine (SVM) to segment the texts from non-texts and thereafter classify them as tables, graphics and halftones. This method outperforms previously existing methods by overcoming various issues associated with the complexity of document images. Experimental results prove the effectiveness of our proposed method. By virtue of our multi-level classification approach, the text components, halftone components, graphic components and table components are accurately classified respectively which would highly improve OCR accuracy to reduce garbage symbols as well as increase compression ratio thereafter simultaneously.

Abstract:

✓ The effect of standard parenteral nutritional formulas on cold-induced vasogenic edema formation in cats was examined and compared to the effects of 5% dextrose, 0.9% saline, and 40.5% mannitol. The amount of vasogenic edema formed during a 3-hour period of fluid infusion following cold injury was quantified by a computerized graphics tablet determination of the volume of Evans blue-dyed white matter. Specific gravity measurements were taken as a measure of white matter water content. Serum osmolality, urine output, arterial blood gases, hematocrit, body temperature, and systolic blood pressure were measured periodically throughout the infusion period. Parenteral nutritional formulas and a 40.5% mannitol solution produced greater changes in serum osmolality than did 5% dextrose or 0.9% saline. Greater changes in serum osmolality were associated with larger calculated volumes of edema in the injured hemisphere and lower water contents in the uninjured hemisphere. The data indicate that hyperosmolar solutions may potentiate vasogenic edema formation when the blood-brain barrier is open.

Abstract:

Introduction: The Clinical Frailty Scale (CFS) has been validated internationally to predict adverse outcomes and mortality. Frailty assessments in the Emergency Departments (ED) are challenging to due to a lack of training and time. We studied the use of a tablet-based CFS that used graphics and short descriptors to assist choice of the 9 frailty categories. Methods: We conducted a prospective observational cohort study of people &gt;65 years seen in the ED of 3 Canadian academic centers. We excluded critically ill patients, and those with significant visual impairment or inability to communicate in English or French. We compared agreement on the tablet-based CFS between 4 categories of assessors: Patients, ED Physicians, trained Research Assistance and Caregivers using the kappa statistic. Results: We enrolled 274/380 eligible patients who provided complete data (72.1%). Their average age was 75.8 years, and 48.9% were female. Their median MOCA score was 23/30 (IQR=17-26) and their median OARS was 26/28 (IQR 22-28). Agreement between physicians and research assistants was good (κ=0.60, 95% CI 0.50-0.70), as was physician-caregiver agreement and patient-caregiver agreement (κ=0.66, 95% CI 0.40-0.93). Agreement between physicians and patients was only moderate (κ=0.47, 95% CI 0.36-0.58). Conclusion: There was less agreement between physicians and patient self-assessments for the CFS compared to physicians-research assistant agreement and care-giver patient assessments of frailty. Future research should validate whether MD, patient, or caregiver rated CFS have higher predictive validity.

Abstract:

ABSTRACT Efficient computer programming is becoming a central requirement in quantitative Earth science education. This applies not only to the early career stage but—due to the rapid evolution of programming paradigms—also throughout professional life. At universities, workshops, or any software training events, efficient practical programming exercises are hampered by the heterogeneity of hardware and software setups of participants. Jupyter notebooks offer an attractive solution by providing a platform‐independent concept and allowing the combination of text‐editing, program execution, and plotting. Here, we document a growing library with dozens of Jupyter notebooks for training in seismology. The library is made “live” through a server that allows accessing and running the notebooks in the browser on any system (PC, laptop, tablet, smartphone), provided there is internet access. The library seismo‐live contains notebooks on many aspects of seismology, including data processing, computational seismology, and earthquake physics, as well as reproducible papers and graphics. It is a community effort and is intended to benefit from continuous interaction with seismologists around the world.

Full text

Abstract:

Subjects observed and reproduced abstract, irregular stimulus models generated by the steady movement of a disk across two-dimensional paths. The paths comprised 3 to 7 randomly oriented linear segments linked head-to-foot. Reproductions were expressed by moving a stylus over the surface of a graphics tablet while the disk was tracing its trajectory (concurrent reproduction), or soon after the disk had finished (delayed reproduction). For both concurrent and delayed conditions, fidelity of reproduction fell with increasing number of segments in the model. Overall quality of reproduction did not differ between the two conditions. When a few models were repeated, interspersed among non-repeated ones, performance improved but only when reproduction was delayed. This improvement was stimulus-selective, not a general improvement with practice. Two additional experiments showed that (i) memory for a seen model is well preserved for at least 6 s, with relatively modest need for rehearsal, and (ii) successful reproduction is possible with remarkably little information having been extracted from key points in the model's trajectory.

Abstract:

Objective. The main goal of this work was to describe the concept of a mobile application that supports the functions of an electronic board for mobile devices with a touch screen. Material and methods. The work uses theoretical methods: a review of the literature on the research problem, analysis of publications, as well as an empirical method of observing the distance work of Tyumen State Medical University teachers. Results. The original article reflects the views of the teacher of the medical university on the problem of distance education during the pandemic of the new coronavirus infection and contains a practical proposal for creating a mobile application with which it is possible to facilitate teacher-student interaction during practical sessions conducted using video conferencing systems. The essence of the proposed concept is to synchronize the operation of a personal computer and a mobile device with a touch screen (phone, tablet), as well as a video conferencing system, in which a remote lesson is held, through a mobile application – a virtual board. Such an application turns the touch screen of a mobile device into an analogue of a graphics tablet, on which you can write using any suitable object. In this application the teacher has administrative permission. He can give or restrict access to the virtual clipboard to any student. This will bring the virtual educational process as close as possible to the real one. Conclusion. When implemented thorough of this idea should ensure improve the end result of education. The main disadvantage of this idea is the need for the teacher and students to have both a computer and a mobile device with a touch screen. Also the operation of this application will be difficult in places with low-speed Internet, or when Internet connection is not available.

Abstract:

Two experiments were conducted to examine manual asymmetries in a one-dimensional aiming task. In Exp. 1, 10 right-handed adults slid a computer mouse 13 cm on a graphics tablet with both the right and left hands to targets of 3 different diameters. Under these conditions, the movement time for the right hand was significantly faster as expected. In Exp. 2, subjects performed similar movements to move a cursor 13 cm on a computer monitor. Thus the study was identical except the stimulus-response mapping was indirect. In this situation, there were no significant differences for either movement time or movement error between hands despite these performance measures indicating that target aiming was more difficult in Exp. 2. Because increases in task difficulty generally result in a greater advantage for the right hand, as indicated by Todor & Smiley, 1985, the present studies suggest that superiority of the right hand in aiming tasks may be diminished when spatial translation is required. Perhaps the spatial translation requires greater involvement of the right hemisphere, a process associated with manual advantage for the left hand, previously suggested by Roy and MacKenzie.

Abstract:

Research on auditory-visual correspondences has a long tradition but innovative experimental paradigms and analytic tools are sparse. In this study, we explore different ways of analysing real-time visual representations of sound and music drawn by both musically-trained and untrained individuals. To that end, participants&rsquo; drawing responses captured by an electronic graphics tablet were analysed using various regression, clustering, and classification techniques. Results revealed that a Gaussian process (GP) regression model with a linear plus squared-exponential covariance function was able to model the data sufficiently, whereas a simpler GP was not a good fit. Spectral clustering analysis was the best of a variety of clustering techniques, though no strong groupings are apparent in these data. This was confirmed by variational Bayes analysis, which only fitted one Gaussian over the dataset. Slight trends in the optimised hyperparameters between musically-trained and untrained individuals allowed for the building of a successful GP classifier that differentiated between these two groups. In conclusion, this set of techniques provides useful mathematical tools for analysing real-time visualisations of sound and can be applied to similar datasets as well.

Abstract:

The reported work aims to objectively and accurately assess the post-stroke clinical condition of visuo-spatial neglect using a series of standardized geometric shape drawing tasks. We present a method implementing existing pencil-and-paper diagnostic methods and define a set of static and dynamic features that can be extracted from drawing responses captured online using a graphics tablet. We also present a method for automatically assessing the constructional sequence of the drawing using Hidden Markov Models. The method enables the automated extraction, position identification and drawing order of individual sides of a shape within a drawing. Discrimination between two populations (a neglect population and stroke subjects without neglect as determined by existing standard assessment methods) using a combination of performance features and constructional sequence is examined across three separate drawing tasks. Results from experimentation show how a combination of sequence and performance features is able to generalize across a wide variety of input samples and obtain a diagnostic classification which can be used alongside other forms of conventional assessment. Furthermore, the application of a multi-classifier combination strategy leads to a significant increase in recognition ability.

Abstract:

Objectives: This study investigates the use of information graphics to display the outputs of health technology assessment (HTA) in the United Kingdom and proposes a more structured approach founded in an analysis of the decision-making requirements of the key stakeholders.Methods: A scoping review of HTA reports was conducted to investigate current practice in the use of information graphics in HTA literature. A classification framework using dimensions of report section, graphical type, and originating research center was devised and used for a full content analysis of the graphical figures in the fifty most recent reports produced for the UK National Health Service's HTA process.Results: Our survey shows that graphical tools are used extensively in HTA reports although less frequently than tables. Use of information graphics varies widely between different report sections and tends to follow conventional lines with little evidence of variance from established practice. The largest variance was found between the quantities of graphics used by different research centers responsible for authoring the reports.Conclusions: HTA makes extensive use of graphics; however, there is little evidence of a systematic or standardized approach, or of much innovation. Significant potential exists to explore the application of information graphics in this field, but there are many research challenges. A contextually based, structured approach to the design of effective information graphics in HTA is proposed as a basis both to investigate the application of existing graphical tools in HTA, and to explore the considerable scope for innovation.
