Abstract:
A walking assistance method may include: detecting a landing time of a foot of a user; and/or initiating gait assistance based on a first joint location of a first leg of the user sensed at the landing time and a second joint location of the user sensed after the landing time. A walking assistance apparatus may include: a driver configured to perform gait assistance of a user; and/or a controller configured to control the driver to initiate the gait assistance based on a first joint location of a first leg of the user sensed at a landing time of a foot of the user and a second joint location sensed after the landing time.
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.
