US 2021/0232269 A1 · TOUCH PANEL INPUT DEVICE, TOUCH PANEL INPUT METHOD, AND RECORDING MEDIUM

Abstract

A touch operation is performed on a touch panel on which a knob for input operation can be placed, using the knob or another operation object. A touch detection unit detects the touch operation in a first detection method and a second detection method which are different from each other. Based on the result of detection in the first detection method, a knob touch point determining unit identifies the position where the touch operation has been performed by the knob, and outputs the touch information. A knob-finger contact determining unit determines whether a finger is in contact with the knob based on the touch information and the result of detection in the second detection method. It is possible to perform, without fail, the determination as to whether a knob or another object is in contact with the touch panel, and whether a finger is in contact with the knob which is in contact with the touch panel.

A touch panel input device including:

a touch panel on which a knob for input operation can be placed, and a touch operation is performed by means of said knob or an operation object other than said knob;
and
processing circuitry
to detect the touch operation on said touch panel in a first detection method and a second detection method which are different from each other;
to identify a position where the touch operation is performed by said knob as a knob touch point, based on a result of detection in said first detection method,
to output touch information concerning said knob touch point;
and
to determine whether a finger is in contact with said knob, based on said touch information, and a result of detection in said second detection method, wherein,
touch points which consist of one or more response points at which an electrostatic capacitance variation satisfying a predetermined condition has occurred in the detection in said first detection method, and which satisfy a predetermined condition are identified as said knob touch points.
