Title:
OPERATION DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2023017534
Kind Code:
A
Abstract:
To provide an operation detection device configured to suppress the variance of coordinates.SOLUTION: An operation detection device 1 includes, as shown in Fig. 1(a) to Fig. 2: a detection unit 3 which detects a touch operation for touching an operation surface 20 to output a detection value S based on a capacitance that increases from before the touch operation; and a control unit 4 serving as a determination unit, which has a determination threshold value Th to determine the start of the touch operation, determines the start of the touch operation when the detection value S becomes equal to or larger than the determination threshold value Th, and determines the end of the touch operation when a first condition based on a maximum detection value Smax after the touch start determination is satisfied.SELECTED DRAWING: Figure 2
