Virtual Localization by Blind Persons
Localization performance and spatial hearing abilities of blind persons are complex issues. In everyday life we rely on the “fact” that blind people can hear better, without thinking of what “better” means. Localization performance depends on many parameters such as properties of the excitation signal, environmental conditions, individual aspects, and visual influence. Our goal was to create a ...
متن کاملAmbisonic sound in virtual environments and applications for blind people
To date there has been much more effort directed to generating credible presentations of virtual worlds in a visual medium than in reproducing corresponding or even self contained worlds with synthesised or recorded sound. There is thus today a disparity in the relative fidelity of these 2 modes in most VR systems. While much work has been done in hi-fidelity and 3 dimensional sound reproductio...
متن کاملPresenting Diagrams in Sound for Blind People
The model used to navigate around diagrams presented in sound is vital to task performance. It is unclear whether presenting position information of the elements is beneficial; a simple method of position presentation was shown to have no benefit. This thesis looks at several aspects of presentation of diagram to blind people using sound. The type of diagram that is used throughout the thesis w...
متن کاملAided Exploration of Virtual Contents by Blind People
This paper describes the main features of a multimodal application, based on haptic/acoustic interaction, that allows visually impaired people to access 3D virtual contents. We have realized a few applications addressing specific contexts, from the exploration of 3D spatial data to the fruition of cultural heritage. Several test sessions, involving users with different stories and different lev...
متن کاملThe use of haptic virtual environments by blind people
This paper describes two studies concerning the use of haptic virtual environments for blind people. The studies investigated the perception of virtual textures and the perception of the size and angles of virtual objects. In both studies, differences in perception by blind and sighted people were also explored. The results have implications for the future design of VEs in that it cannot be ass...
