Abstract:
For visually impaired people the hear sense
replace the seeing sense. To help people moving in an
unstructured environment in the real world we try to
make a 3D virtual audio reality. The mostly used
method are HRTF (Head Related Transfer Functions), a
set of audio filters. A simulation model in Matlab
demonstrates the possibility to tell visually impaired
people where is the obstacles. We use the simulation to
make a man-machine interface, which is part of a big
project to guide these people to walk and work in the
real world.
