Abstract

User interface systems and methods are described below that allow vehicle operators to control systems, devices, and/or functions of a vehicle by tapping on surfaces of vehicle components. The “tap-controlled vehicle interfaces (“TCVI”)” use sensors like accelerometers to sense arid recognize parameters of operator tapping. The parameters may include the location, strength, repetition, and rhythm of the tapping for example. The TCVI translates the parameters to specific commands that are then used to control corresponding vehicle systems of the host vehicle.

1. A device comprising:

a sensor system that includes an acoustic sensor and a reference sensor; and

a signal processing system (SPS) coupled to the sensor system, wherein the SPS detects tapping of a user on a surface by comparing signals of the acoustic sensor and the reference sensor, identifies an acoustic signature of the detected tapping, selects a parameter of a remote component that corresponds to the acoustic signature, and automatically initiates control of the selected parameter of the selected remote component using information of the acoustic signature.

2. The device of claim 1, wherein the surface includes an external area of at least one of a steering device, a shift control device, and a console of a host system.

3. The device of claim 1, wherein the acoustic sensor is an accelerometer.
