A navigation module for technological aids for disabled user is presented. and acceptability y criteria are considered in the design of this module, Different AND Usability levels of autonomy for the navigation module are considered for allowing an active interaction of the user with the technological aids. A standardized protocol for the integration of input-output devices for robotic assistive systems is also used. The navigation module is tested on an powered wheelchair and an autonomous
