  • Touch detection device, display device with touch detection function, and control method thereof
    Patent number: 11467682
    Abstract: According to an aspect, a touch detection device includes: first detectors that output first signal values corresponding to contact of detection target objects with first regions; at least one second detector that outputs at least one second signal value corresponding to at least one first force applied by the detection target objects to press at least one second region corresponding to the first regions; and a controller that calculates at least one third signal value corresponding to at least one second force applied by at least one of the detection target objects to the at least one second region, based on the first signal values, the at least one second signal value, and at least one reference value corresponding to a third force per at least one of the first signal values.

  • Pointing device and touch detection system
    Patent number: 10168803
    Abstract: According to an aspect, a pointing device used to indicate a position on a touch detecting device includes: a first output unit provided to a body of the pointing device with which a hand of a user holding the pointing device comes into contact; and a first signal generating unit that generates a palm detection signal including a first code and different from a signal detected in a touch operation with the pointing device, and outputs the palm detection signal to the first output unit.
