US 2023/0400925 A1 · TACTILE FEEDBACK APPARATUS

Abstract

The present invention provides a tactile feedback device that detects a user operation based on touch without erroneous detection, providing stable tactile feedback. This device includes: an operated section that receives a user operation based on touch; a touch detection section for detecting touch on the operated section; a load detection section that detects a load on the operated section due to touch; a vibration actuator that generates vibration and outputs the vibration to the operated section; and a driving control section that drives, in response to the detection of touch and detection of load, the vibration actuator to vibrate the operated section, feeding back tactile sensation to a user, wherein the load detection section stops detection of a load during vibration.
