In this research, a novel type of interface by seat surface inclination for electric wheelchair is developed in order to improve the current Joystick one. The sensibility evaluation experiments based on low and high velocities are carried out. By using the tilt sensor in this study, the data of cushion's inclinations are recorded to manipulate the wheelchair. The reformed wheelchair is evaluated by the SD method. 20 students are participated in the experiment which is executed in a room with 5m×5m size. The respondents answer the surveys after operating. First, the experiment results indicate that the interface form is feasible. The comments on the low velocity mode are relatively well among the two velocities. Compared with taking fully automatic ones, when the user is taking our developed wheelchair, the low velocity mode is preferred.
