Abstract

A method for analyzing a gait pattern includes: measuring, by a plurality of force sensing resistor (FSR) sensors, foot pressure values, and outputting the measured foot pressure values, respectively; searching for a maximum pressure local area in which the sum of the output values from the FSR sensors included in each of a plurality of pressure local areas is maximized; calculating a center of pressure (COP) with respect to the detected maximum pressure local area; and analyzing a gait pattern by adding the calculated COP to the trajectory of COPs.

Claims (13)

1. A method for analyzing a gait pattern, the method comprising:

measuring, by a plurality of force sensing resistor (FSR) sensors, foot pressure values, and outputting the measured foot pressure values, respectively;

searching for a maximum pressure local area at which the sum of the output values from the FSR sensors included in each of a plurality of pressure local areas is maximized;

calculating a center of pressure (COP) with respect to the detected maximum pressure local area; and

analyzing a gait pattern by adding the calculated COP to the trajectory of COPs.

2. The method of claim 1 , further comprising:

removing an island as an error from the output values of the plurality of FSR sensors.

3. The method of claim 2 , wherein the output values of the plurality of FSR sensors are values obtained by sampling the foot pressure values by more than the total number of rows of left and right FSR sensors.

4. The method of claim 1 , wherein the pressure local areas are an aggregate of the FSR sensors each connected with an output value greater than a pre-set reference value.

5. The method of claim 1 , wherein the detecting of the maximum pressure local area comprises:

calculating the sum of the output values from the FSR sensors included in each of the pressure local areas;

determining the calculated sum of the output values as a total pressure value representing each of the pressure local area; and

detecting a pressure local area having a maximum total pressure value among the plurality of pressure local areas, as the maximum pressure local area.
