Title:
TOUCH SENSOR DEVICE, TOUCH OPERATION DETECTION SENSITIVITY CHANGING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/144821
Kind Code:
A1
Abstract:
A touch position detection unit (100) detects a user's touch position on the basis of a signal output from a touch sensor. A change instruction reception unit (102) receives an instruction to change the detection sensitivity of the touch position detection unit (100) from a user. A sensitivity changing unit (103) changes the detection sensitivity on the basis of the change instruction. If the change instruction indicates that the sensitivity is to be increased, the sensitivity changing unit (103) sets the detection sensitivity to the sensitivity indicated by the change instruction, and then initiates a noise check to check whether or not noise is detected on the basis of the detection result from the touch position detection unit (100), wherein if noise is detected before elapse of a predetermined time period, the sensitivity changing unit (103) returns the detection sensitivity to the value of the sensitivity immediately before the change was made.
