Claim 6:
7. The method according to claim 4, wherein recognizing a position of one leg using the dynamic programming algorithm based on the position of the buttocks comprises:
calculating a score of each of the sensor units of a first lower array based on the short-term vibration energy characteristic, the first lower array being an array of sensor units from a tail of the smart cushion to the position of the buttocks; and
tracing back a first leg path with a highest sum of scores based on the short-term vibration energy characteristic in the first lower array starting from the each sensor unit at the position of the buttocks by means of the dynamic programming algorithm, and determining the first leg path as the position of the one leg, wherein the sensor units of adjacent rows where the first leg path passes are connected with one another.
