INFORMATION INPUT APPARATUS, INFORMATION INPUT METHOD, AND PROGRAM

摘要

An information input apparatus includes: a touch pad; a touch information detecting unit which detects touch information that is information resulting from an operator contacting the touch sensor with a finger; a touch operation start position detecting unit which detects, using the touch information, a touch operation start position that is a start position of a touch operation performed by the operator; a touch operation recognition condition storage unit which stores a plurality of touch operation recognition conditions each for recognizing one of types of touch operation, in association with each of touch operation start positions; and a touch recognizing unit, which recognizes the touch operation, using the touch operation recognition conditions stored in association with the touch operation start position detected by the touch operation start position detecting unit, to determine a type of the touch operation.

1. An information input apparatus comprising:
a touch sensor which is a sensor for inputting information; a touch information detecting unit configured to detect touch information that is information resulting from an operator contacting the touch sensor with a finger; a touch operation start position detecting unit configured to detect, using the touch information, a touch operation start position that is a start position of a touch operation performed by the operator; a touch operation recognition condition storage unit configured to store a plurality of touch operation recognition conditions each for recognizing one of types of touch operation, in association with each of touch operation start positions; and a touch operation recognizing unit configured to recognize the touch operation, using the touch operation recognition conditions stored in association with the touch operation start position detected by the touch operation start position detecting unit, to determine a type of the touch operation; and a grip information detecting unit configured to detect grip information about the operator relative to the information input apparatus, wherein the grip information includes at least one of a type of holding hand with which the operator holds the information input apparatus, a grip position on the information input apparatus gripped by the operator, a direction angle of the information input apparatus relative to a gripping hand of the operator, and a length of the finger used for a touch operation by the operator, and the touch operation recognizing unit is configured to calculate a difference between a predetermined reference grip state and the at least one of the detected grip position, direction angle, and length of the finger, adjust the touch operation start position so that the difference becomes smaller, determine the type of the touch operation, using the adjusted touch operation start position, and output an operation amount indicating a magnitude of the touch operation.
