Abstract
A method and apparatus for recognizing a motion of a user are provided. The apparatus may map each of right leg angle information and left leg angle information to context information by comparing each of the right leg angle information and left leg angle information to a comparison value and/or preset threshold, may generate a motion event corresponding to the context information based on a criterion, and may recognize the motion of the user based on the motion event and a previous motion of the user.
Claims17
A method of recognizing a motion of a user, the method comprising:
- mapping each of right leg angle information and left leg angle information to context information according to a comparison of each of the right leg angle information and left leg angle information to a comparison value;
- generating a motion event corresponding to the context information based on a criterion;
- and
- recognizing a motion of the user based on the motion event and a previous motion of the user.
An apparatus for recognizing a motion of a user, the apparatus comprising:
- a mapping unit configured to map each of right leg angle information and left leg angle information to context information based on a comparison of each of the right leg angle information and left leg angle information to a comparison value;
- a motion event generator configured to generate a motion event corresponding to the context information based on a criterion;
- and
- a motion recognizer unit configured to recognize a motion of the user based on the motion event and a previous motion of the user.
A walking assistance apparatus, comprising:
- a driver configured to drive a right hip joint and a left hip joint of a user;
- a sensor configured to sense right and left hip joint angle information;
- an inertial measurement unit (IMU) sensor configured to sense upper body angle information of the user;
- and
- a controller configured
- to map each of right leg angle information and left leg angle information to context information based on a comparison of each of the right leg angle information and left leg angle information to a comparison value,
- to generate a motion event corresponding to the context information based on a criterion to recognize a motion of the user based on the motion event and a previous motion of the user, and
- to control the driver, the right leg angle information and left leg angle information being calculated based on the right and left hip joint angle information and the upper body angle information.
