The ATAD project is a new assistive product aiming to help the visually impaired to move in a more secure and autonomous way in unknown environments. It involves stereovision blocks to estimate the depth map of the surroundings, a new sonification protocol with redundancies to decrease the training needed and bone conduction to transmit the auditory information to the users. Using a Human-Centered Design process, it has been evaluated in several steps during the design and implementation up to the final tests with blind participants in real life situations. The whole project as well as the different steps and contributions are presented in this paper.
