This paper presents the preliminary tests of an adapted user interface that performs an hybrid fuzzy-Deformable Virtual Zone(DVZ) pilot. The proposed concept uses a safely guidance algorithm for the powered wheelchair user and a laser range sensor to avoid collision. An adapted user interface is developed so that the accessibility and the mobility of disable or aged people especially those suffering from low cognitive abilities will be enhanced. Trials with the proposed algorithm detected obstacles and avoid them in 80% of trials with different objects and generated safe paths for the interface user.
