Title:
INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/220749
Kind Code:
A1
Abstract:
An input device having: an operation panel member which has an input operation screen and detects the coordinates of the operation location within the input operation screen; a first sensor, a second sensor and a third sensor which each detect the distance between said sensor and the operation panel member, and are positioned within a reference plane separated from the operation panel member; and a signal processing device for processing the signals from the operation panel member and the first, second and third sensors. Therein, the operation panel member is capable of being angled relative to the reference plane in response to the load applied at the operation location, and the signal processing device calculates the amount of displacement before and after operation of the operation panel member at the operation location from the coordinates of the operation location within the input operation screen detected by the operation panel member, and the distances which were detected by the first, second and third sensors.
