Claim 5:
6. The method according to claim 4, wherein recognizing a position of a torso using the greedy algorithm based on the position of the buttocks comprises:
calculating a score of each of the sensor units of a second upper array based on the short-term vibration energy characteristic, the second upper array being an array of sensor units from the position of the buttocks to the head of the smart cushion;
selecting a sensor unit with a largest score based on the short-term vibration energy characteristic as a torso sensor unit in each of rows of the second upper array by means of the greedy algorithm; and
sequentially connecting the selected torso sensor units in the rows as a torso path, and determining the torso path as the position of the torso.
