Vision is crucial for the development of space perception and cognition. Blind people show an impairment in some auditory, motor and social skills. Early onset blindness also impacts on psychomotor, social and emotional development. Despite the huge improvement of technological devices, many of the solutions proposed to visually impaired people are not widely accepted by adults and not easily adaptable to children. The goal of this thesis work is to develop an optimized assessment system for visually impaired people who are involved in training sessions for the improvement of audio-motor abilities, in particular children under a rehabilitative program with ABBI (Audio Bracelet for Blind Interaction). Within the thesis we developed a new set-up to be used independently by rehabilitators without the supervision of the researchers. The new device is an all-in-one wireless and sensitized set of loudspeakers, easy to mount, controllable from a free, dedicated Android app, offering to the therapist a complete testing kit for a periodically and short-lasting evaluation of children’s response to the training.
