Abstract:
1. A mobile information device comprising: a housing; a plurality of keys disposed on one surface of the housing; a control unit configured to execute processing in response to a touch operation performed on at least one of the keys; and N proximity sensors (N≧2) disposed on the surface of the housing, and each configured to detect a proximity state of a sensing target, wherein when at least two predetermined proximity sensors among the N proximity sensors detect the proximity state, the control unit blocks the processing in response to the touch operation on at least one of the keys, wherein the at least two predetermined proximity sensors are separated from one another by a distance equivalent to at least one key, and are each adjacent to at least one of the keys, and wherein the at least two predetermined proximity sensors include two proximity sensors that sandwich at least one of the keys therebetween.
