Title:
ELECTROSTATIC INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/132199
Kind Code:
A1
Abstract:
Provided is an electrostatic input device which is capable of activating an electrostatic capacitance detection unit before contact is determined so that false detection is suppressed. The electrostatic input device includes: an electrostatic capacitance detection unit that is arranged in an operation unit which is operated by a living body and that detects electrostatic capacitance; and a control unit that switches the electrostatic capacitance detection unit to an activated state when the electrostatic capacitance detection unit is in a standby state and contact with the living body has not been detected, and if an increase of electrostatic capacitance detected by the electrostatic capacitance detection unit reaches or exceeds a first prescribed value a prescribed number of times within a prescribed period.
