Abstract:
The purpose of this study is to analyze the relationship between passenger’s posture behavior and comfort while riding omni-directional wheelchair. First, an algorithm to transform the obtained data in the sensor coordinates using acceleration sensor into the vehicle coordinates by means of proposed correction algorithm. Its effectiveness is demonstrated by experiments. Second, analysis on the relationship between acceleration of wheelchair movement, passenger’s posture behavior and comfort sensation in the riding motion to forward, backward and lateral direction is studied. Posture behavior of passenger’s head and chest is measured by acceleration sensors, and comfort sensation of passenger is evaluated by applying the Semantic Differential (SD) method and a Paired Comparison Test. Finally, through a lot of experiment, influence factors concerning comfort while riding to wheelchair are discussed.
