Virtual World Accessibility with the Perspective Viewer
نویسندگان
چکیده
Virtual worlds are mostly inaccessible to blind users, due to their exclusively graphical interfaces. We developed the Perspective viewer for Second Life and OpenSim virtual worlds, which enables blind users to explore and navigate Second Life virtual worlds with relative ease. The Perspective viewer allows different tools to be modularly added to the viewer, to enable comparison amongst different tools proposed in accessibility research. The Perspective viewer and its set of navigation and exploration tools are described here, with an analysis of the types of tools essential to the blind user in the navigation and exploration of virtual worlds. In particular, the manner in which the audio channel uses and filters information in the navigation of the virtual world, is highlighted. The development of the viewer enabled us to make several recommendations for virtual world accessibility standards.

On the other hand immersive virtual reality systems engage the user and bring the user into the virtual world, often as a participant rather than just as an observer. This paper looks at applying virtual reality display te...
متن کاملEnhancing Fish Tank VR
Fish tank VR systems provide head coupled perspective projected stereo images on a display device of limited dimensions that resides at a fixed location. Therefore, fish tank VR systems provide only a limited virtual workspace. As a result, such systems are less suited for displaying virtual worlds that extend beyond the available workspace and depth perception problems arise when objects that ...
متن کاملThe Varrier Auto-Stereographic Display
The goal of this research is to develop a head-tracked, stereo virtual reality system utilizing plasma or LCD panels. This paper describes a head-tracked barrier auto-stereographic method that is optimized for real-time interactive virtual reality systems. In this method, a virtual barrier screen is created simulating the physical barrier screen, and placed in the virtual world in front of the ...
متن کاملOn the Design of Perspective Displays
FUNCTIONS OF INFORMATION DISPLAYS ometric appearance of a real environment by visually presenting static and dynamic features as if the viewer were to be actually looking at them. A viewer looking at such an image can thus interpret the image as if it represented a virtual space on the far side of the picture plane. Vehicle instrument panels, road signs, warning placards and maps are all exampl...
