Objective : Autonomy is particularly important for patients with partial mobility. Despite using assistive devices such as a wheelchair or a walker, maintaining one's capacity for independence can be tedious. Feedback solutions added to assistive devices can increase autonomy of patient with limited mobility. In this context, the researchers of the IH2A chair on disability at INSA Rennes are developing open sources feedback solutions for various assistive devices. The solution consists in the use of sensors to detect obstacles combined with a vibratory feedback, and/or a visual light feedback informing the user about obstacles. Experiments with able-bodied participants as well as trials with end-users are currently being conducted to demonstrate the acceptability of the feedback solution.

Material / Patients and Methods : Trials with blindfolded able-bodied participants have been conducted to evaluate the efficiency and reliability of our feedback solution. Moreover, the solution has been equiped on the rollator of a blind user with cerebellar syndrome. Since then, he is using his walker in his daily-life with the vibratory feedback. We also plan to equip a second end-user who is using a power wheelchair.

Results : Trials are in progress and publications have shown results regarding efficiency as well as acceptability of our feedback solution.

Discussion - Conclusion : Our ambition is to eventually allow patient with limited mobility to increase their autonomy. Our feedback solution is cost-effective and open-source, therefore it can be easily acquired and reproduced by any fablab. By not being designed to a specific assistive device, our solution is adaptable and tunable to the particular needs of each individual.
