Virtual Reality As Navigation Tool: Creating Interactive Environments For Individuals With Visual Impairments, Nick Murphy
Virtual Reality As Navigation Tool: Creating Interactive Environments For Individuals With Visual Impairments, Nick Murphy
Master of Science in Computer Science Theses
Research into the creation of assistive technologies is increasingly incorporating the use of virtual reality experiments. One area of application is as an orientation and mobility assistance tool for people with visual impairments. Some of the challenges are developing useful knowledge of the user’s surroundings and effectively conveying that information to the user. This thesis examines the feasibility of using virtual environments conveyed via auditory feedback as part of an autonomous mobility assistance system. Two separate experiments were conducted to study key aspects of a potential system: navigation assistance and map generation. The results of this research include mesh models …
Towards Understanding And Developing Virtual Environments To Increase Accessibilities For People With Visual Impairments, Miao Dong
Master of Science in Computer Science Theses
The primary goal of this research is to investigate the possibilities of utilizing audio feedback to support effective Human-Computer Interaction Virtual Environments (VEs) without visual feedback for people with Visual Impairments. Efforts have been made to apply virtual reality (VR) technology for training and educational applications for diverse population groups, such as children and stroke patients. Those applications had already shown effects of increasing motivations, providing safer training environments and more training opportunities. However, they are all based on visual feedback. With the head related transfer functions (HRTFs), it is possible to design and develop considerably safer, but diversified training …
Second Life Complements The Internet For Reference Librarians, Florence Tang
Second Life Complements The Internet For Reference Librarians, Florence Tang
Georgia Library Quarterly
The article describes the Second Life culture as an interactive virtual environment from the perspective of a reference librarian. The cited advantages of using Second Life are synchronous interaction with other people, clearer appearance of chat text messages, incorporation of social norms, and accessibility. Among the noted obstacles to using Second Life are its price, intentional distress of other avatars, empty virtual public places, less hierarchy among participants, chatting via rapid typing, and quick change of landscapes and avatars.
