Motion Rail: A Virtual Reality Level Crossing Training Application

This paper presents the development and usability testing of a Virtual Reality (VR) based system named 'Motion Rail' for training children on railway crossing safety. The children are to use a VR head mounted device and a controller to navigate the VR environment to perform a level crossing task and they will receive instant feedback on pass or failure on a display in the VR environment. Five participants consisting of two male and three females were considered for the usability test. The outcomes of the test was promising, as the children were very engaging and will like to adopt this training approach in future safety training

Talk to the Virtual Hands: Self-Animated Avatars Improve Communication in Head-Mounted Display Virtual Environments

Background When we talk to one another face-to-face, body gestures accompany our speech. Motion tracking technology enables us to include body gestures in avatar-mediated communication, by mapping one's movements onto one's own 3D avatar in real time, so the avatar is self-animated. We conducted two experiments to investigate (a) whether head-mounted display virtual reality is useful for researching the influence of body gestures in communication; and (b) whether body gestures are used to help in communicating the meaning of a word. Participants worked in pairs and played a communication game, where one person had to describe the meanings of words to the other. Principal Findings In experiment 1, participants used significantly more hand gestures and successfully described significantly more words when nonverbal communication was available to both participants (i.e. both describing and guessing avatars were self-animated, compared with both avatars in a static neutral pose). Participants ‘passed’ (gave up describing) significantly more words when they were talking to a static avatar (no nonverbal feedback available). In experiment 2, participants' performance was significantly worse when they were talking to an avatar with a prerecorded listening animation, compared with an avatar animated by their partners' real movements. In both experiments participants used significantly more hand gestures when they played the game in the real world. Conclusions Taken together, the studies show how (a) virtual reality can be used to systematically study the influence of body gestures; (b) it is important that nonverbal communication is bidirectional (real nonverbal feedback in addition to nonverbal communication from the describing participant); and (c) there are differences in the amount of body gestures that participants use with and without the head-mounted display, and we discuss possible explanations for this and ideas for future investigation

Avatars using computer/smartphone mediated communication and social networking in prevention of sexually transmitted diseases among North-Norwegian youngsters

<p>Abstract</p> <p>Background</p> <p>Sexually transmitted diseases (STDs), especially the <it>Chlamydia trachomatis</it> bacterial infection, a common cause of infertility, are highly prevalent in developed countries, and a worrying problem in North Norway, where the incidence of chlamydia twice the Norwegian average. Seventy percent of reported chlamydia cases are found in people below 25 years of age, and although its spread could be controlled with proper prevention, young people are more aware of the risks of unwanted pregnancy than their risk of acquiring a STD. Information and Communication Technologies, including, the Internet, social media and/or smartphones, should be valued for sexual health promotion for their potential to engage young audiences. And in these media, avatars guarantee anonymity to users when handling sensitive information. The main objective of this project is to achieve that North Norwegian youngsters become more aware of STDs through the use of popular technologies among young people.</p> <p>Methods</p> <p>A Virtual Clinic for Sexually Transmitted Diseases (VCSTD) will be developed. The VCSTD will provide early guidance and reliable information sources concerning reproductive health, delivered in a novel and innovative way to the younger population. The VCSTD consists of an “avatar” supported intervention in a serious gaming and e-learning environment, which will bypass direct physical access (in person) to reliable medical information, as well as allowing the youngsters to share that information in social media, and thus helping the VCSTD to be disseminated to more people.</p> <p>Data analyses will be conducted on publically available health data relevant to STDs in Troms and Finnmark, like the absolute number of chlamydia tests, the amount of emergency contraception medication sold, and the number of abortions. Also, usage data of the system and experiences of usefulness will be explored through participants’ voluntary responses to a feedback form available in the VCSTD.</p> <p>Discussion</p> <p>This study will examine the usefulness of an online public health intervention that aims to promote healthy sexual practices among North-Norwegian youngsters. If shown to be effective, the intervention could prove to be an affordable and widely accessible intervention to decrease risky sexual practices in younger population.</p
