Abstract:

Abstract Corona crisis and video conferencing software – two terms that now belong together. However, the demands controllers have on video conferencing software can quickly reach the limits of data protection regulations. In recent years, the progressive development of video conferencing software has already excited many users and led to significant growth. In ad hoc situations, like the Corona pandemic, issues regarding data protection are all too often neglected. This is fatal considering the fact that the implementation of video conferencing software is accompanied by a large number of data protection and security issues that must be addressed and weighed up by the controller. At first glance, technically feasible solutions can quickly turn out to be “Trojan horses” and pose a serious threat to personal data. Therefore, the selection, set-up and use of data protection-compliant video conferencing software is of great importance for controllers. This article aims to examine relevant questions regarding data protection and security management from a European legal perspective. In particular, the detailed analysis of the requirements of the General Data Protection Regulation (GDPR) as well as the practical consequences for the controller should provide practicians an overview of the legal problems associated with the implementation and use of video conferencing software.

Abstract:

Along with the development of technologies on computer, electronic and communication, there are more and more applications of digital image acquisition and processing technology used in computer and portable systems, such as videophone, digital cameras, digital television, video monitoring, camera phones and video conferencing etc. Digitized image makes image digital transmit with high quality, which facilitates image retrieval, analysis, processing and storage. In applications such as video conferencing, it is a crucial premise to capture videos. So, in this paper, we mainly introduce the video capture technology by exploiting the VFM video services library developed by Microsoft. Software based on VFW can directly capture digital videos or digitize the traditional analog videos and then clipping them.

Abstract:

Video conferencing is very common nowadays, and it may contemplate heterogenous devices (e.g., smartphones, notebooks, game consoles) and networks in the same session. Developing video conferencing systems for this myriad of devices with different capabilities requires special attention from system designer. Scalable video coding (SVC) is a prominent option to mitigate this heterogeneity issue, but traditional Internet protocol (IP) networks may not fully benefit from such a technology. In contrast, software-defined networking (SDN) may allow better utilization of SVC and improvements on video conferencing components. This paper evaluates the performance of video conferencing systems adopting SVC, SDN and ordinary IP networks, taking into account throughput, delay and peak signal-to-noise ratio (PSNR) as the metrics of interest. The experiments are based on Mininet framework and distinct network infrastructures are also considered. Results indicate SDN with SVC may deliver better video quality with reduced delay and increased throughput.

Abstract:

This research note aimed to highlight the reflections of the researcher while conducting videoconferencing interviews as a part of his doctoral research project. The researcher drew some inferences based on recent literature and two videoconferencing interviews conducted with the doctoral students via Zoom. It was a crucial experience to deal with the recruitment of research participants, building rapport/understanding, especially with the female participant, exchanging nonverbal cues between researcher and participants, considering socio-cultural aspects of the participants, writing the interview summaries and getting them reviewed by the participants. Moreover, technological aspects were also considered important like having a PC, laptop or android of good condition with consistent internet connectivity, appropriate software (Zoom) and recording of the interviews, backup of the recordings, making sure electricity and other equipment essential for videoconferencing interviews was available. Besides, reviewing the order of questions and time for the research interviews is also important for videoconferencing interviews. The researcher believes that it might be possible to increase the trustworthiness of the videoconferencing interviews by considering all these aspects.

Abstract:

Objective: To determine whether an evaluation of a wireless ultrasound transducer could be completed remotely. Materials and Methods: Video conferencing was used for communication between a sonographer and a minimally trained operator to allow evaluation of a flat linear array transducer that communicated via Wi-Fi with a smartphone and the probe vendor’s software. A tissue-mimicking phantom was used for quantitative testing, while scanning human models allowed qualitative assessments. Video conferencing using a tablet camera directed at the smartphone screen or transducer allowed the sonographer to view images, and guide the operator on probe positioning, and image optimization techniques. Results: All tests were completed during three 60-minute video conferences. Assessments of models were more challenging than tests using the phantom. The glare from ambient lighting sometimes made it difficult to view the smartphone screen. A connectivity limitation, which has since been resolved, prevented simultaneous use of video conferencing and the transducer software on the smartphone. Conclusion: This study confirmed that an evaluation of a wireless ultrasound transducer can be successfully performed remotely.

Abstract:

Role plays have served an instrumental role in social work education by providing opportunities for students to acquire interaction skills. This project tested various online video conferencing tools to facilitate role plays for students who live in different locations and who are unable to be at the same place at the same time. Key features of the technology included the ability to facilitate real-time interaction, compatibility with laptops and Wi-Fi connections, and the ability to record sessions for later viewing and feedback. Method: Case study design. Results: Students were able to use the videoconferencing software with minimal support. Video quality was not always ideal with contributing factors being the time of day students used the software. There were no distinguishable time and effort demands associated with the online video conferencing compared to classroom role plays. Some students found use of the technology caused them to feel disconnected from their peers compared to face-to-face encounters, while other students found the encounter more intimate in that the pressure to perform in front of others was not felt. Implications: Video conferencing is a promising tool to facilitate social work role plays. Future research needs to assess the acquisition of specific skills compared to traditional classroom students.

Abstract:

Cooperation between physicians in hospitals in rural areas can be assisted by desktop-conferencing using a satellite link. For six weeks, medical desktop-conferencing was tested during daily clinical conferences between the Virchow-Klinikum, Berlin, and the Medical Academy, Wroclaw. The communications link was provided by the German Telekom satellite system MCS, which allowed temporary connections to be established on demand by manual dialling. Standard hardware and software were used for videoconferencing, as well as software for medical communication developed in the BERMED project. Digital data, such as computed tomography or magnetic resonance images, were transmitted by a digital data channel in parallel to the transmission of analogue video and audio signals. For conferences involving large groups of people, hardware modifications were required. These included the installation of a video projector, adaptation of the audio system with improved echo cancellation, and installation of extra microphones. Learning to use an unfamiliar communication medium proved to be uncomplicated for the participating physicians.

Abstract:

In this paper we present a conferencing architecture compliant with the IP Multimedia Subsystem (IMS) specification. To the purpose, we embrace a practical approach, by describing an actual implementation of an open source centralized video-conferencing system, called CONFIANCE, capable to offer advanced communication experience to end-users through the effective exploitation of mechanisms like session management and floor control. CONFIANCE has been designed to be fully compliant with the latest standard proposals coming from both the IETF and the 3GPP and can be considered as an outstandingexample of a real-time application built on top of the grounds paved by the SIP protocol. We will discuss in the paper both the design of the overall conferencing framework and the most important issues we had to face during the implementation phase.

Abstract:

Adults with Alzheimer’s disease (AD) and their caregivers represent a segment of the population with low levels of moderate-intensity physical activity (MPA) and limited options for increasing MPA. The purpose of this study was to evaluate the feasibility of a group video conference approach for increasing MPA in adults with AD and their caregivers. Adults with AD and their caregivers attended 30-min group exercise sessions three times per week for 12 weeks. Exercise sessions and support sessions were delivered in their homes on a tablet computer over video conferencing software. Nine adults with AD/caregiver dyads enrolled, and seven completed the 12-week intervention. Adults with AD attended 77.3% of the group exercise sessions, and caregivers attended 79.2% of group exercise sessions. Weekly MPA increased in both adults with AD (49%) and caregivers (30%). Exercise delivered by group video conferencing is a feasible and potentially effective approach for increasing MPA in adults with AD and their caregivers.

Abstract:

This paper analyses three performance metrics namely average throughput, average network load and average video conferencing packet end-to-end delays under the influence of black hole attack in a Mobile Ad Hoc Network, using the ad hoc on-demand distance vector routing protocol. The simulation was carried out on Riverbed Modeler Academic Edition software. Simulation results show that the average throughput, average network load and average video conferencing packet end-to-end delay decreases as the number of black hole attack nodes is increased. Also, the effects of the influence of black hole attack nodes tend to decrease due to mobility of the nodes. It was observed that when the destination nodes move closer to the source nodes and get in to the latter’s transmission range, the effects of the black hole attack is greatly minimized.

Abstract:

World is networked through internet today. There are various mobile Applications, which help people in many different ways, based on the purpose of the application. Due to the pandemic lockdown, now-a-days, the classes are conducted online, through modes like, video lectures and video conferencing. Apart from the forced school environment, one can create their own environment to study through online classes. Apart from the established online courses that already have study material and subtitles, the live classes for under graduate students, who begin to explore online education, get the first blow in understanding and educating themselves. Many students find it difficult to listen to lectures through video conferencing because of a cluster of students with different proficiency levels. In a classroom scenario, with the use of blackboard method or power-point presentation, the students somehow get the idea of the subject. That way, if not by listening to the teacher, visual aids help the students to grasp in a better fashion. The purpose of this study is to propose the development of a mobile application, to reduce the difficulties in listening lectures online. The application might act as a caption provider in the video lecture that helps the students to comprehend the subject better. This study is based on a survey taken among 100 undergraduate students from a particular institution in India, to enquire the hardships and hurdles of learning through online lectures. The result of the analysis provided the preference of captioned videos in video lectures for enhancing the purpose of online lectures. This study tries to prove the hardships of non-native speakers of English, while attending video lectures and providing a solution to the aforementioned, based on the survey, by implementing the idea of a mobile application to provide captions, during the live lecture.

Abstract:

The article raises the problem of using video conferencing services in network educational communities in the context of virtualization of the educational space when organizing the interaction of students in the process of online learning in informatics. Changes in the education system associated with the development of social networks and network communities are discussed, and new opportunities provided by them to the teacher for including students in various types of educational and cognitive activities are analyzed. The concepts of “network community” and “social networks” are revealed. The role of network communities and social networks as collective subjects of social information and educational activities on the Internet is demonstrated. From the standpoint of the implementation of the principle of interactivity of interaction of subjects of educational activity in network communities, the analysis of educational interaction of schoolchildren in the format of video conference based on the Internet is carried out. The characteristics of the capabilities of popular services for network interaction of participants in the educational process when organizing training in the video conference format are described, examples of open software solutions are given. The experience of using video conferencing services in teaching informatics and robotics in the context of the implementation of the educational process in the networked educational communities of the Internet is revealed. The author's approach to the use of tools of popular services for organizing video conferencing in the implementation of interactive training in promising areas of informatics and robotics in the process of joint activities on the Internet is proposed. The results obtained contribute to the theory of informatization of education and can be used in practice by teachers who implement the educational process with schoolchildren using interactive interaction services and Internet resources.

Abstract:

Teacher-provided opportunities to respond are a powerful strategy for improving behavior and academic outcomes of students with disabilities. However, online instruction makes opportunities to respond more challenging to implement. For the purposes of this article, online teaching refers to synchronous instruction taking place via video conferencing software (e.g., Zoom, Microsoft Teams, Canvas Conferences, Blackboard Collaborate). This article presents strategies teachers can use to elicit individual responses from students through oral responses, response cards, and action responses.

Abstract:

Few challenges of the COVID-19 pandemic strike at the very core of our humanity as the inability of family to sit at the bedside of their loved ones when battling for their lives in the ICU. Virtual visiting is one tool to help deal with this challenge. When introducing virtual visiting into our ICU, we identified 5 criteria for a sustainable system that aligned with patient-family-centered care: virtual visiting needed to (1) simulate open and flexible visiting; (2) be able to accommodate differences in family size, dynamics, and cultural practices; (3) utilize a video conferencing platform that is private and secure; (4) be easy to use and not require special teams to facilitate meetings; and (5) not increase the workload of ICU staff. There is a growing body of literature demonstrating a global movement toward virtual visiting in ICU, however there are no publications that describe a system which meet all 5 of our criteria. Importantly, there are no papers describing systems of virtual visiting which mimic open and flexible family presence at the bedside. We were unable to find any off-the-shelf video conferencing platforms that met all our criteria. To come up with a solution, a multidisciplinary team of ICU staff partnered with healthcare technology adoption consultants and two technology companies to develop an innovative system called HowRU. HowRU uses the video conferencing platform Webex with the integration of some newly designed software that automates many of the laborious and complex processes. HowRU is a cloud based, supported, and simplified system that closely simulates open and flexible visiting while ensuring patient and family privacy, dignity, and security. We have demonstrated the transferability of HowRU by implanting it into a second ICU. HowRU is now commercially available internationally. We hope HowRU will improve patient-family-centered care in ICU.

Abstract:

This research paper compares two popular backbone network technologies – Gigabit Ethernet and Asynchronous Transfer Mode (ATM). ATM has been a popular choice for years for providing multimedia applications over the network effectively by making use of its features like Quality of Service (QoS). Gigabit Ethernet matches ATM’s functionality by providing higher bandwidth at lower cost, less complexity and easier integration into the existing Ethernet technologies. Hence, it becomes important to compare these two technologies against various network performance metrics to find out which technology performs better for what type of applications under what circumstances. This research paper will analyze and compare the performance of those two technologies based on the throughput, end-to-end delay for Voice and Video conferencing and jitter for the Voice applications. For this purpose, two different simulations were created, one for the Gigabit Ethernet and the other one for the ATM network, using the popular commercial and academic simulation software – OPNET modeler.

We propose a new video conferencing system that uses an array of cameras to capture a remote user and then show the video of that person on a spherical display. This telepresence system has two key advantages: (i) it can capture a near-correct image for any potential observer viewing direction because the cameras surround the user horizontally; and (ii) with view-dependent graphical representation on the spherical display, it is possible to tell where the remote user is looking from any viewpoint, whereas flat displays are visible only from the front. As a result, the display can more faithfully represent the gaze of the remote user. We evaluate this system by measuring the ability of observers to accurately judge which targets the actor is gazing at in two experiments. Results from the first experiment demonstrate the effectiveness of the camera array and spherical display system, in that it allows observers at multiple observing positions to accurately tell at which targets the remote user is looking. The second experiment further compared a spherical display with a planar display and provided detailed reasons for the improvement of our system in conveying gaze. We found two linear models for predicting the distortion introduced by misalignment of capturing cameras and the observer's viewing angles in video conferencing systems. Those models might be able to enable a correction for this distortion in future display configurations.

Abstract:

Video coding is an imperative part of the modern day communication system. Furthermore, it has vital roles in the fields of video streaming, multimedia, video conferencing and much more. Scalable Video Coding (SVC) is an emerging research area, due to its extensive application in most of the multimedia devices as well as public demand. The proposed coding technique is capable of eliminating the Spatio-temporal regularity of a video sequence. In Discrete Bandelet Transform (DBT), the directions are modeled by a three-directional vector field, known as structural flow. Regularity is decided by this flow where the data entropy is low. The wavelet vector decomposition of geometrically ordered data results in a lesser extent of significant coefficients. The directions of geometrical regularity are interpreted with a two-dimensional vector, and the approximation of these directions is found with spline functions. This paper deals with a novel SVC technique by exploiting the DBT. The bandelet coefficients are further encoded by utilizing Set Partitioning in Hierarchical Trees (SPIHT) encoder, followed by global thresholding mechanism. The proposed method is verified with several benchmark datasets using the performance measures which gives enhanced performance. Thus, the experimental results bring out the superiority of the proposed technique over the state-of-arts.

Abstract:

Under the current global conditions, strong emphasis is put on saving resources and reducing costs, migrating to collaborative unified communications solutions and developing open-source Web applications. The secure video-conferencing system will mainly use VoIP and WebRTC technologies to make multimedia calls, allowing end-users mobile and remote access (MRA) and therefore to facilitate communication between different networks, as well as the accessibility and the interoperability with any type of technology and device. This article will analyze the scalable implementation of the real-time communications network, providing redundancy and load balancing, therefore ensuring the high availability of the entire collaborative communications system. The call control and the dial plan are done through the Unified Call Manager software and WebRTC videoconferencing external access functionality is provided by configuring Traversal Using Relays around NAT (TURN) service across the Expressway Series server pair (Core & Edge). The ability to manage and monitor virtual meetings remains the responsibility of the open-source management tools.

Abstract:

Not everyone can afford to own and operate a scanning electron microscope. Everyone can, however, access images and instruments in a variety of ways, depending on the objective. Remote access capability is a result of recent developments in desktop computers, software, and the World Wide Web. Some of these developments and some suggestions for future resource development will be reviewed here.With the arrival of commercially available, digitally controlled SEMs in the 1980s, it became possible to control microscope operation with a desktop computer and the appropriate software. By connecting a desktop computer to the microscope via the Internet or dedicated data lines such as ATMs, remote control of microscopes became a reality. Although analog microscopes are not as readily controllable over the Internet, their video data stream is easily captured, digitized, and dispatched to remote observers using low-cost consumer video conferencing programs. These approaches enable users at one location to observe their samples in a microscope located elsewhere. However, transfer rates over the Internet fluctuate wildly depending on network traffic, at times making remote access or control almost impossible. Dedicated data lines ensure a relatively stable transfer rate, but at a significantly higher cost.

Abstract:

This paper describes the architecture, design patterns, and implementation of a Unified Communications Solution (UCS) over a home grown thin implementation of IP Multimedia Subsystem (IMS). This thin-IMS implementation makes use of IMS core components, and can serve as a first step towards migration to full IMS. The unified communications solution offers a rich set of services including duplex VoIP, video conferencing, instant messaging, media sharing, child position tracking, active contacts, and email reading. Subscriber profile is leveraged by a targeted video advertisement preview service as a payment method for calls terminating at landline or mobile networks. Subscribers can also use prepaid service for calls terminating outside of the IP networks. In addition to system and software design patterns, the paper addresses critical deployment issues, such as scalability, NAT traversal, network interconnect, ease of service provisioning and administration, and last but not least, user experience. Finally, the paper contrasts the thin-IMS platform to 3GPP standard IMS release 7 specifications.

Abstract:

Launched in 2000 and held every year since, the Bioinformatics Open Source Conference (BOSC) is a volunteer-run meeting coordinated by the Open Bioinformatics Foundation (OBF) that covers open source software development and open science in bioinformatics. Most years, BOSC has been part of the Intelligent Systems for Molecular Biology (ISMB) conference, but in 2018, and again in 2020, BOSC partnered with the Galaxy Community Conference (GCC). This year’s combined BOSC + GCC conference was called the Bioinformatics Community Conference (BCC2020, bcc2020.github.io). Originally slated to take place in Toronto, Canada, BCC2020 was moved online due to COVID-19. The meeting started with a wide array of training sessions; continued with a main program of keynote presentations, talks, posters, Birds of a Feather, and more; and ended with four days of collaboration (CoFest). Efforts to make the meeting accessible and inclusive included very low registration fees, talks presented twice a day, and closed captioning for all videos. More than 800 people from 61 countries registered for at least one part of the meeting, which was held mostly in the Remo.co video-conferencing platform.

Abstract:

The development of a scanning electron microscope (SEM) suitable for instructional purposes has created a large number of outreach opportunities for the Materials Science and Engineering (MSE) Department at Iowa State University. Several collaborative efforts are presently underway with local schools and the Department of Curriculum and Instruction (C&I) at ISU to bring SEM technology into the classroom in a near live-time, interactive manner. The SEM laboratory is shown in Figure 1.Interactions between the laboratory and the classroom use inexpensive digital cameras and shareware called CU-SeeMe, Figure 2. Developed by Cornell University and available over the internet, CUSeeMe provides inexpensive video conferencing capabilities. The software allows video and audio signals from Quikcam™ cameras to be sent and received between computers. A reflector site has been established in the MSE department that allows eight different computers to be interconnected simultaneously. This arrangement allows us to demonstrate SEM principles in the classroom. An Apple Macintosh has been configured to allow the SEM image to be seen using CU-SeeMe.

Abstract:

The availability of heterogeneous devices has rapidly changed the way people access the World Wide Web that includes rich content applications such as video streaming, 3D games, video conferencing, and mobile TV. However, most of these devices' (i.e., mobile phone, PDA, smartphone, and tablet) capabilities differ in terms of built-in software and library (what they can display), display size (how the content appears), and battery supply (how long the content can be displayed). In order for the digital contents to fit the target device, content adaptation is required. There have been many projects focused on energy-aware-based content adaptation that have been designed with different goals and approaches. This paper reviews some of the representative content adaptation solutions that have been proposed during the last few years, in relation to energy consumption focusing on wireless multimedia streaming in mobile devices. Also, this paper categorizes the research work according to different classifications of multimedia content adaptation requirements. In addition, we discuss some energy-related challenges content adaptation systems.

Abstract:

In this paper, we propose a new face detection and tracking algorithm for real-life telecommunication applications, such as video conferencing, cellular phone and PDA. We combine template-based face detection and tracking method with color information to track a face regardless of various lighting conditions and complex backgrounds as well as the race. Based on our experiments, we generate robust face templates from wavelet-transformed lowpass and two highpass subimages at the second level low-resolution. However, since template matching is generally sensitive to the change of illumination conditions, we propose a new type of preprocessing method. Tracking method is applied to reduce the computation time and predict precise face candidate region even though the movement is not uniform. Facial components are also detected using k-means clustering and their geometrical properties. Finally, from the relative distance of two eyes, we verify the real face and estimate the size of facial ellipse. To validate face detection and tracking performance of our algorithm, we test our method using six different video categories of QCIF size which are recorded in dynamic environments.

Abstract:

This article identifies ten myths about Internet Art, and explains the difficulties museums and others have understanding what it means to make art for the Internet. In identifying these common misconceptions, the author offers insight on successful online works, provides inspiration to Internet artists, and explains that geographical location does not measure success when making art for the Internet. The article also mentions that the World Wide Web is only one of the many parts that make up the Internet. Other online protocols include e-mail, peer-to-peer instant messaging, video-conferencing software, MP3 audio files, and text-only environments like MUDs and MOOs. The author concludes his list of myths with the idea that surfing the Internet is not a solitary experience. Online communities and listservers, along with interactive Internet artworks that trace viewers and integrate their actions into respective interfaces, prove that the Internet is a social mechanism.
