1. An information processing apparatus comprising:
- a contact detection unit capable of detecting a plurality of contact coordinates on an operation surface, and outputting a contact detection signal as a detection result;
a load detection unit for detecting a load applied to the operation surface; and
a coordinate estimation unit, wherein when a load detection result provided by the load detection unit satisfies a pressed coordinate retrieval condition, the coordinate estimation unit estimates a pressed coordinate from among the plurality of contact coordinates on the operation surface, on the basis of at least the contact detection signal, the coordinate estimation unit determining a contact coordinate that changes most greatly from coordinate history information obtained from the contact detection signal before the load detection result satisfies the pressed coordinate retrieval condition, and adopting the determined contact coordinate as the pressed contact coordinate.
