An omnidirectional power-assist wheelchair must be adaptable to needs of individual attendants. We modified our neuro-fuzzy controller to improve diagonal movements. We also developed an innovative touch panel interface providing easy real-time input and feedback. Experiments confirmed the wheelchair's adaptability to user needs.

For improving the operability of an omni-directional wheelchair provided with a power assist system, the system must be able to adapt to the individual characteristics of the many different attendants that will use it. For achieving this purpose, an innovative human-interface using a touch panel that provides easy input and feedback information in real time of the operation of a power-assisted wheelchair was developed. The system was tested experimentally with many different attendants and the results show that in addition to providing a human friendly interface by using the touch panel system with monitor it can adapt successfully to the particular habits of the attendants.
