An abundance of haptic rendering schemes have been developed to help further presence and immersion in virtual environments. Increasing realism is the main driving force behind this development. Schemes have progressed from simple one-dimensional springs to six degree of freedom particle models, with a wealth of surface and material properties. Because of their relative unimportance, haptic ren...

BACKGROUND Oral presentations of clinical cases by medical students during medical rounds in hospital wards are a source of anxiety and little is known about how this anxiety can be alleviated. The objective of this study was to investigate whether video-based feedback of public oral presentations can reduce anxiety in 4th year medical students. METHODS Multicentre randomized study conducted ...

The present study intended to evaluate EFL students' performance on a traditional method of writing assessment in comparison to an alternative assessment technique by taking into account the effects of teacher and peer feedback. Moreover, the attitudes of the participants regarding assessment procedures and activities were focused in this study. To this end, thirty male and female language lear...

We examined the effects of individualized video modeling on the accurate implementation of behavioral interventions using a multiple baseline design across 3 teachers. During video modeling, treatment integrity improved above baseline levels; however, teacher performance remained variable. The addition of verbal performance feedback increased treatment integrity to 100% for all participants, an...

The purpose of this paper was to explore research-based applications for using video podcasts in an online learning environment. Five key video podcast uses were examined including administration, instruction, student assignments, feedback, and community. Administrative video podcasts provide course information on areas such as learning goals, lesson plan instructions, course policies, and home...

Although the importance of health and exercising as a way to maintain fitness and physical wellbeing is widely recognized, it is often difficult for people to persist with a regular workout schedule. In this paper, we propose a solution to this problem through “Collaborative Digital Sports.” This is a digital sports environment where participants are given a shared goal. Through the use of body...

Peer feedback can be a tool to help higher education students develop presentation skills. This process supported by using online tools that enable peers provide annotated spe...

|With the success of the Internet and exibility of MPEG-4, transporting MPEG-4 video over the Internet is expected to be an important component of many multimedia applications in the near future. Video applications typically have delay and loss requirements, which cannot be adequately supported by the current Internet. Thus, it is a challenging problem to design an e cient MPEG4 video delivery ...

Wyner-Ziv (WZ) video coding – a particular case of distributed video coding (DVC) – is a new video coding paradigm based on two major Information Theory results: the Slepian-Wolf and Wyner-Ziv theorems. Recently, practical WZ video coding solutions were proposed with promising results. Many of the solutions available in the literature make use of a feedback channel (FC) to perform rate control ...
