Abstract
Patients with walking difficulties often rely on mobility aids for moving around by themselves. A Cycling Wheel Chair has been developed as an option in order to provide such patients an opportunity to fully utilize their bodies, including lower limbs and nerves. This paper presents the enhanced indoor safety concept, where the Cycling Wheel Chair warns the patient as he blindly approaches static objects, rather than completely taking over their controls. Also, quantitative evaluation of the driving ability with warning levels allows a patient to perform a rehabilitation exercise away from hospitals. The results of such evaluation can later be used by doctors for further driving ability assessments.
