Title:
Operation device
Document Type and Number:
Japanese Patent JP6005417
Kind Code:
B2
Abstract:
Provided is an operation device that suppresses differences in operational feeling resulting from the amount of sensitivity of a detection subject. The operation device (1) is primarily configured, in broad outline, from: a touch panel (2) that outputs a first capacitance in accordance with the distance between a finger and an operation surface (20); a determination unit (3) that determines contact to the operation surface (20) by the finger by comparing the first capacitance acquired from the touch panel (2) and a pre-set first threshold (30); a discrimination unit (4) that, after contact has been determined by the determination unit (3), discriminates on the basis of the first capacitance the amount of sensitivity of the finger contributing to the capacitance detected by the touch panel (2); an alteration unit (5) that alters the first threshold (30) to a second threshold (51) on the basis of the amount of sensitivity of the finger discriminated by the discrimination unit (4); and a control unit (6) that detects an operation by the finger by comparing a second capacitance acquired by the touch panel (2) to the second threshold (51) acquired from the alteration unit (5).
