Apparatus, method and program for analyzing golf sway

A golf sway analyzing apparatus, the apparatus comprising:

• a sensor unit configured to sense a pressure and a foot spacing of a user;
• a control unit configured to analyze a sway of the user based on a sensing signal of the sensor unit;
• a display unit configured to display analysis data analyzed by the control unit;
• and
• a storage unit configured to store the analysis data and reference data,
• wherein, in the sensor unit, a plurality of pressure sensors are arranged one-dimensionally or two-dimensionally on a mat plate, and
• wherein the control unit is configured to:
• determine locations of feet of the user based on the sensing signal of the sensor unit;
• calculate center-of-gravity and the foot spacing of the user in response to a golf swing of the user, and estimate and record an upper body reference line in the storage unit;
• classify record data, which is recorded in the storage unit, for each golf swing step of the user;
• analyze the sway of the user by comparing the record data classified for each golf swing stage with the reference data;
• and
• allow the display unit to display analysis data including the analyzed sway of the user, and
• wherein, in the sensor unit, a single sensor including one of a capacitive pressure sensor, a resistive pressure sensor, and a hybrid pressure sensor, or complex sensors including at least two of the capacitive pressure sensor, the resistive pressure sensor, and the hybrid pressure sensor are arranged one-dimensionally or two-dimensionally on a mat plate.
