Title:
SENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/110455
Kind Code:
A1
Abstract:
The purpose of the present embodiment is to provide a sensor device with which it is possible to perform sensing with high accuracy.
The sensor device of the present embodiment comprises a capacitance-type touch panel, a knob provided so as to be capable of rotating around a rotating shaft, a conductor held in the knob and facing the touch panel in a portion of the circumference centering around the rotating shaft, and a sensor controller for controlling the touch panel. The sensor controller holds a reference signal that corresponds to capacitance while the conductor is not facing the touch panel, and detects the first coordinate of the conductor in a first sensing period on the basis of the reference signal and a first sensor signal received from the touch panel while the conductor faces a first position of the touch panel.
