1. A method of selecting a function of a device, comprising:
- detecting a resonant frequency generated by a tapping on a selection region of a device housing; and
selecting a function of the device based on the detected resonant frequency,wherein the selection region includes a first selection feature forming a first shape in the device housing and a second selection feature forming a second shape in the device housing,the first and second selection features comprise concentric geometric shapes, andthe concentric geometric shapes of the first selection feature have at least one of a different number and a different diameter than the concentric geometric shapes of the second selection feature.

7. An electronic device, comprising:
-
a device housing having a selection region including a first selection feature and a second selection feature, the first selection feature configured to generate a different resonant frequency than the second selection feature in response to tapping each of the first and second selection features; a sensor to detect the resonant frequencies generated by the first and second selection features; and a processing circuit configured to receive sensor data from the sensor corresponding to the detected resonant frequency from each of the first and second selection features and to select a function of the electronic device based on the sensor data corresponding to the detected resonant frequency, wherein the first selection feature defines a first cavity in the device housing and the second selection feature defines a second cavity in the device housing the first and second cavities are made up of concentric shapes, and at least one of a number, depth and diameter of the concentric shapes of the first cavity is different than the second cavity. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
