Project Details


The aim of the project is to develop a highly effective acoustic user
interface for visually impaired and blind people. To improve the usability
over commonly used "screen readers", 3-dimensional sound simulation is
employed to simulate surrounding acoustic rooms via headphones. To create
those virtual rooms, the Ambisonic approach was chosen and will be
implemented on the TI DSP Evaluation Module. The project will result in a
test system which is designed to replace an operating-systems desktop based
on audio cues only. Similar to the graphical desktops, the acoustic rooms
can contain icons which result in actions if clicked on. This might cause a
program to start or open a text file. User are able to navigate in the
environment with a joystick, they can "go" from one room to another, where
the room acoustic differs among the rooms and is an additional information
for the user. For visually impaired and blind people, this might be a
remarkable improvement in computer access which is important to empower
them for equal participation in the labor market. not assigned KP: ISIS project (Integration, Service, Information and Education), Austrian Bundessozialamt
