Operation assistance of a voice-controlled electric wheelchair

We propose a voice-controlled electric wheelchair with a system for detecting its position and direction. Thus far, we have studied systems that incorporated voice instructions with our indoor navigation equipment using RF tags. The operability of a wheelchair was measured in the same environment for different operating methods. We found that one very effective method is to store the possible stopping positions and angles of rotation for the desired directions in RF cards, which could then adequately assist the movement of a wheelchair.
