Abstract
An object of the present invention is to realize mutual adaptation for mutual synchronizing in a man-machine system and make it applicable to the site of walking aid. A walking aid system of the present invention comprises: a sensor section (2) for sensing the motion rhythm of a walker, a recording section (33) for recording values of measurements of the motion rhythm sensed with the sensor section 2, a target setting section (34) for setting a target value for the motion rhythm of the walker, a timing generating section (36) for generating a timing signal according to the difference between the measurement and the target value, and a stimulus generating section (4) for generating rhythm stimulus that is recognizable by the walker, according to the timing signal generated with the timing generating section (36).

10. A walking aid system for controlling a motion rhythm of a walker as a controlled object having a characteristic of a nonlinear system comprising:
-
a sensor section for sensing the motion rhythm of the walker; a main section including a nonlinear system module having dynamic behavior as a nonlinear system and for establishing a synchronized state through entrainment in interaction between the nonlinear system module and the walker, and further including a feedback system module for performing feedback to the nonlinear system module in the synchronized state; and a stimulus generating section for generating rhythm stimulus to the walker; wherein the nonlinear system module generates a timing signal to constitute the synchronized state with the motion rhythm of the walker through the entrainment and the rhythm stimulus generated according to the timing signal is transmitted to the walker through the stimulus generating section, and the feedback system module, in the synchronized state, calculates a relative amount for synchronizing, compares the relative amount for synchronizing with a relative amount as a target, calculates an appropriate feedback control amount, and applies feedback so as to adjust a parameter of the nonlinear system module for changing the relative amount for synchronizing to control the motion rhythm of the walker by causing the relative amount for synchronizing to converge to the target relative amount. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
