Three-dimensional Audio Interfaces for the Blind

Project Type: Master/Diploma Thesis
Student: Frauenberger Christopher
Mentor: Gernot Kubin

 

 This thesis is dealing with alternative interaction modes for visually impaired and blind people to use computers. The aim of the proposed approach is to exploit the human hearing capabilities to a better degree than this is done by screen-readers. A surrounding, three-dimensional audio interface is potentially increasing the information flow between a computer and the user. This thesis presents a virtual audio reality (VAR) system which allows computer users to explore a virtual environment only by their sense of hearing. Besides the details of the technical realisation, this thesis also investigates the user requirements for the target group. Their special abilities and disabilities are stated which must be considered when designing interfaces for this group of users.
