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