Abstarct: The objective of this study is to implement a force feedback joystick on a smart electric wheelchair provided with a set of range sensors. The force feedback is calculated according to the proximity of the obstacles and help the user, without forcing him, to move towards the free direction. The first stage of the project consists in validating the interest of this method of control. In this paper we present our methodology and some first experimental results.

Key words: assistive technology, haptic feedback, human-machine interaction, electric wheelchair.
