The aim of this work is to study its potentialities in this context, and more particularly to assist to the powered wheelchairs control. After a bibliographical study on this question, we propose to model the wheelchair piloting task with an alternative of the classical Fitts law. The goal is to objectively evaluate the interest of a force feedback on the control joystick of an electric wheelchair.enPowered wheelchairassistive technologyhaptic feedbackFitts lawArticle
