A device includes a substrate, strain gauges, and a controller coupled to the strain gauges. The substrate has a front surface and an opposing rear surface, the front surface including a button representation and the rear surface including a button area corresponding to the button representation. The strain gauges are mounted on the rear surface in proximity to the button area. The controller receives information indicating multiple electrical signal amplitudes, each of the electrical signal amplitudes corresponding to one strain gauge of the plurality of strain gauges, each electrical signal amplitude representing an amount of deformation of the corresponding strain gauge. The controller estimates a location of a pressure applied and/or the magnitude of force applied on the front surface of the substrate based on the received information. The controller also can receive location information of multiple user presses from a separate set of sensors.

A system and method for providing access to a vehicle operation includes a first user-input interface, a second user-input interface, and a vehicle controller. The first user-input interface is configured to interact with a user via a swipe-up input. The second user-input interface is configured to interact with the user via an application independent of the swipe-up input. The vehicle controller is configured to control the vehicle operation in response to detecting a first swipe-type user-input via the first user-input interface and a second user-input via the second user-input interface within a predetermined time.

A hand dryer that includes a capacitance-detection-type proximity sensor structure that detects a capacitance generated in a capacitance detection electrode to detect a presence or absence of an object to be detected, includes a plurality of capacitance-detection-type proximity sensor structures. While one of the capacitance-detection-type proximity sensor structures is in operation, an operation of at least another of the capacitance-detection-type proximity sensor structures is stopped to operate the capacitance-detection-type proximity sensor structures during different periods of time.
