- humans have different walking patterns depending on the size of the body, the state of muscle strength, and the walking speed.
- the walking pattern varies depending on the purpose of movement (for example, rehabilitation purpose, training purpose, gait improvement purpose, motion (force) assist purpose, etc.). Therefore, the assist that is most naturally felt by each wearer is different, and the assist suitable for the purpose is also different. Therefore, a large number of assist patterns are assigned to each phase so that an optimum assist pattern can be selected from a plurality of assist patterns according to the target assist.
- the autonomous control means 112 is stored in the data storage means 113 and parameters indicating the wearer's movement state such as the joint angle detected by the joint angle detection means 103 and the gravity center position detected by the gravity center position detection means 104.
- the task and phase of the operation of the wearer 1 are specified by comparing with the reference parameter.
- the autonomous control means 112 identifies the phase according to the state of the wearer's movement, the optimum control pattern is selected from the assist patterns assigned to the phase according to the preset purpose.

- the display unit 141 displays a coordinate system (coordinate plane) in which the vertical axis (y axis) corresponds to the assist force and the horizontal axis (x axis) corresponds to the response speed.
- the wearer 1 designates a position with a large value on the vertical axis in the coordinate system to increase the assist force via the input means 142, and designates a position with a small value on the vertical axis in order to reduce the assist force. .
- the wearer 1 designates a position with a small value on the horizontal axis of the coordinate system (the left side in the figure) when he wants to increase the response speed through the input unit 142 (to increase the response of the assist given).
