Claim 8:
9. The method according to claim 4, wherein recognizing a position of one leg on the basis of the position of the buttocks using the greedy algorithm comprises:
calculating a score of each of the sensor units of a second lower array based on the short-term vibration energy characteristic, the second lower array being an array of sensor units from the position of the buttocks to the tail of the smart cushion;
selecting a sensor unit with a largest score based on the short-term vibration energy characteristic as a first leg sensor unit in each of rows of the second lower array by means of the greedy algorithm; and
sequentially connecting the selected first leg sensor units in the rows as a first leg path and determining the first leg path as the position of the one leg.
