DRIVER aims to help people with special needs to navigate an electric wheel chair. For this purpose, the navigational capabilities of robotic wheel chairs will be properly enhanced to allow semi-autonomous navigation. The user controls the navigation proccess and determines the destination. The resulted system will be secure, user-friendly and easily adaptive to the current robotic wheel chairs. Thus, the DRIVER"s main goal is the development, evaluation and assessment of a navigational support system that could be used as an add-on module on robotic wheel chairs.
