The context of the project is disability and a partial or total deterioration of mobility (tetraplegics (50,000 in France + 1200/year), Cerebral palsy (125,000 + 1500 / year), Stroke (130 000 per year in France of whom 30,500 with disabling consequences), Locked-in syndrome (LIS) (600 in France), for whom the visual and hearing functions are normal or only slightly impaired.

These people whose mobility impairment can be very high (residual mobility), may only be able to safely control their wheelchair on their own by using the software and technology currently available on the market. Although there are a lot of options available in this latter category (vocal command, breathing/inspiration, with the tongue, etc.), they are often very unpopular or even rejected due to the cognitive overload that they induce.
Other more complex and costly solutions require a prior knowledge of the environment which automatically restricts the users to a re-education unit or a flat.

Recognising this problem, Handinum has come up with a new solution by combining the use of the visual and cerebral activity to operate and control an electric wheelchair. This non-invasive solution gives the user back a relative level of autonomy, increases acceptability rates for technical assistance and user safety. Furthermore, by taking into account issues related to mental fatigue and emotional state, it is able to reinforce the reliability and robustness of the control/operate functions.
