Claim One:
1. An information processing apparatus comprising: an operation display unit for displaying a display screen and detecting an operation location on the display screen based upon a user operation on the display screen; a pressure detecting unit including a plurality of pressure sensors for detecting a pressure value according to the user operation on the operation display unit for each of the plurality of pressure sensors; an operation type determining unit for determining a type of the user operation, based upon a detection result from the operation display unit; a deriving unit for selectively deriving a barycentric location on the display screen based upon detection results from the plurality of pressure sensors, based upon a determination result from the operation type determining unit; and an estimating unit for estimating a pressure value on the operation location, based upon a derivation result from the deriving unit and upon information of barycentric location candidates in which information of a combination of pressure values on a plurality of locations on the display screen is recorded in correspondence with information of the barycentric location.
