Abstract: A standing motion assist device includes a support mechanism attached to a leg of a user to assist the user with motion, a sensor including first and/or second sensors that measure and output posture information and myoelectric potentials of the user, respectively, the sensor outputting measurement data including first measurement data measured after a sitting motion of the user sitting in a chair starts and second measurement data measured after the sitting motion ends, a memory that stores the measurement data, and a processor that controls the support mechanism. The processor detects the sitting motion and identifies the chair type based on the first measurement data, detects the start of a motion of the user standing from the chair based on the second measurement data, and outputs assist information corresponding to the identified chair type and used by the support mechanism to assist the user with standing.

Abstract: A standing-up assistance apparatus includes a first sensor that measures a muscle potential of a lower leg of a user, a second sensor that measures a knee angle of the user, a processor that determines whether starting to assist the user in a standing-up motion from a seated state is possible, based on, at least, the measured muscle potential and the measured knee angle, and outputs an instruction signal if the processor determines that starting to assist the user in the standing-up motion is possible, and an assistance mechanism. The assistance mechanism starts assisting the user in the standing-up motion when the assistance mechanism receives the instruction signal from the processor.

Abstract: A rise action assistance device according to an aspect of the present disclosure is provided with: a myoelectric potential acquirer that acquires a myoelectric value of a sitting user's tibialis anterior muscle, and a myoelectric value of the sitting user's vastus lateralis muscle or a myoelectric value of the sitting user's vastus medialis muscle; an angle acquirer that acquires a bend angle of the sitting user's upper body; a detector circuit that detects a start of a rise action by the user, based on the myoelectric value of the user's tibialis anterior muscle, the myoelectric value of the user's vastus lateralis muscle or the myoelectric value of the user's vastus medialis muscle, and the bend angle of the user's upper body; and an assistor that starts assistance of the rise action after the start of the rise action is detected.
