Abstract: An input device for detecting a change in capacitance in accordance with proximity of an object is provided. The input device includes: a sensor unit including multiple capacitive coupling parts formed between multiple driving electrodes and multiple sensing electrodes; a capacitance detector for detecting a capacitance value of each of the capacitive coupling parts; and a two-dimensional data generating unit for generating a two-dimensional data matrix consisting of the capacitance values of the capacitive coupling parts. When a target row or a target column in the two-dimensional data matrix matches a first pattern indicating that multiple capacitive coupling parts each having a capacitance value greater than a reference value are arranged consecutively, the input device updates the reference value.

Abstract: Operation input device with few gesture operation erroneous detections is provided. Operation input device includes substrate; plurality of detecting electrodes provided on substrate surface; detecting unit detecting capacitance occurring between each detecting electrode and operating body upon operating body being brought close to substrate; and determining unit determining whether gesture operation by operating body has been performed. Detecting electrodes include first and second electrodes of which capacitance values decrease/increase to match amount of movement of operating body when operating body is moved in longer direction. Upon sensing of operation of moving operating body after being stopped relative to detecting electrodes, or operation of stopping operating body after being moved relative to detecting electrodes, gesture operation by operating body is determined to have been performed. Operating body is determined to be stopped when changes in sum of, and ratio between, capacitance values of first and second electrodes are ≤predetermined values.

Abstract: In a door handle sensor system, a door handle device includes an electrostatic sensor to detect the user with respect to a door handle, and a pressure sensor to detect the operating force applied to the door handle. A control device determines whether the position of an operation is in a first end section, a second end section, or a center section of the door handle, and controls an unlatched state based on the determination result and the value detected by the pressure sensor. The electrostatic sensor includes a first electrode including multiple first electrode parts and a second electrode including multiple second electrode parts arranged alternately with the first electrode parts. The first electrode part other than the endmost first electrode part in the first direction and the second electrode part other than the endmost second electrode part in the first direction are arranged in the center section.
