Abstract: A detection method includes: obtaining periodically and repeatedly sensor values output from a capacitive sensor; determining whether the sensor values obtained exceed threshold Th1; calculating, as first difference value Δ1X of each of target sensor values CX, a difference between target sensor value CX and sensor value CX+1 immediately before the target sensor value; calculating, as second difference value Δ2X of each of target sensor values CX, a difference between (i) first difference value Δ1X of target sensor value CX and (ii) first difference value Δ1X+1 of sensor value CX+1 immediately before target sensor value CX; comparing each of second difference values Δ2X calculated and threshold Th2, and selecting one sensor value CRet based on a result of the comparing; and outputting the one sensor value CRet selected.

Abstract: An input device includes a pressure sensitive unit and a sensing unit. The pressure sensitive unit includes a clicking part and a pressure sensor. The clicking part has a press surface and is configured to provide a sense of click to an operation body which applies pushing force to the press surface. The pressure sensor is disposed on an opposite side of the clicking part from the press surface. The sensing unit is aligned with the pressure sensitive unit when viewed from a front side of the press surface and is configured to sense that the operation body comes in proximity to or comes into contact with a second detection surface.

Abstract: An input device includes one or more pressure detectors. Each of the one or more pressure detectors includes an electrode, an elastic body on the electrode, a pressing member disposed on an opposite side of the elastic body from the electrode, and a protective member. The protection member is disposed between the elastic body and the pressing member and has higher strength than the elastic body.
