Outline of Final Research Achievements

The distance-based measurement model for walking and standing/sitting behaviors by using only a pair of two proximity sensors was proposed. Specifically, the proposed measurement scheme allowed an interface to determine between standing behaviors and sitting ones, not requiring visual sensors such as cameras. Moreover, a motion-generation model is developed, enabling a lower-limb assist device to generate its motions so as to correspond to the measurement model. To demonstrate the effectiveness of the models, experiments were performed where 30 subjects including six persons over the age of 75 participated. From a practical standpoint, these results were quite encouraging. From these results, we are able to confirm that the proposed models could provide the potential users of the assist device with easy, reliable maneuverability without invading their own privacy.
