Expert system for the decision on the ability to drive power wheelchair based on fuzzy logic

This paper presents an expert system based on the fuzzy logic. The main idea is to study and realize a tool to help the ergo-therapist for the decision on the capacity of the disabled person to drive safely a power wheelchair. The decision will also concern the optimal number of sensors and the suitable type of assistance (light, sound...) to integrate on this wheelchair in order to assist the handicapped during his navigation. In order to test the efficiency of this expert system, based on fuzzy logic, a 3D simulator for driving wheelchair was created.
