Abstract
A motion feedback method is disclosed. The method includes: acquiring a frame in which a scene of the motion performed by a user is captured through a camera; acquiring motion data of the user by analyzing the captured frame; acquiring pressure data measured in response to the user's motion through a pressure sensor; generating comparison target data by normalizing the motion data and the pressure data so as to correspond to pre-prepared reference data according to the expert's motion; and comparing the reference data and the comparison target data to generate feedback data for the user's motion, and outputting the generated feedback data.
Claims9
A motion feedback method comprising:
- acquiring a frame in which a scene of a motion of a user is captured through a camera;
- acquiring motion data of the user by analyzing the frame;
- acquiring pressure data measured in response to the motion of the user through a pressure sensor;
- generating comparison target data by normalizing at least one of the motion data and the pressure data so as to correspond to reference data pre-prepared according to a motion of an expert;
- and
- comparing the reference data and the comparison target data to generate feedback data for the motion of the user, and outputting the generated feedback data,
- wherein normalizing the pressure data comprises at least one of:
- transforming a range of pressure values of the pressure data to correspond to a range of reference pressure values included in the reference data;
- and
- correcting the pressure values of the pressure data so that the pressure values of the pressure data correspond to the reference pressure values included in the reference data.
A motion feedback system comprising:
- a storage unit that stores a frame in which a scene of a motion of a user is captured through a camera, and pressure data measured in response to the motion of the user through a pressure sensor;
- and
- a control unit that acquires motion data of the user by analyzing the frame, generates comparison target data by normalizing at least one of the motion data and the pressure data so as to correspond to reference data pre-prepared according to a motion of an expert, and compares the reference data and the comparison target data to generate feedback data for the motion of the user and outputs the generated feedback data
