Title:
APPARATUS AND METHOD FOR DETERMINING STIMULUS INCLUDING TOUCH INPUT AND STYLUS INPUT
Document Type and Number:
Japanese Patent JP2021009722
Kind Code:
A
Abstract:
To provide a capacitive sensor for detecting a stimulus.SOLUTION: A capacitive sensor includes first and second electrodes defining a capacitive coupling, and a processing unit electrically coupled to the first and second electrodes to determine the presence of a stimulus on the basis of a rate of a change of the capacitive coupling. A substrate is positioned adjacently to the first and second electrodes, where the stimulus corresponds to placement of an object against the substrate. The processing unit is operative to determine a time rate of the change on the basis of successive measurement of the capacitive coupling and in response to the capacitive coupling being greater than a predetermined reference value.SELECTED DRAWING: Figure 36
