The SOunding Landscape

An electronic travel aid for the blind

The objective of this project is to develop a technology that will enable blind people to see the world with their ears. By equipping the blind person with a portable computer, earphones and a

stero camera pair, it is possible to give him a three-dimensional  reconstruction of the scene that is encoded by appropriate sound synthesis techniques, called sonification,  the acoustic analogous of visualization.


Sponsored by HP under the






There are two operation modes:

  1. The system sonifies  the position of a laser spot produced by a laser pointer handled by the  blind person;
  2. The system sonifies the whole scene by assigning suitable sounds to different patches of the disparity map.
