Abstract: A system for and method of illuminating a contact (or touch) device such as a fingerprint sensor are disclosed. In an exemplary system, a touch sensor system has a surface or contact area and comprises a substantially transparent molding positioned over the contact area and a dynamic illuminator positioned to show through the molding. The dynamic illuminator is for indicating a status of the touch sensor system, such as power on, standby, error, low power, an input mode for receiving user input, or a selected operating mode. The touch sensor system includes any one of a fingerprint sensor, a miniature joystick, a touch-sensitive navigation disc, a touch-sensing navigation pad, an N-way pressure-sensitive directional control, to name a few touch sensor devices. In one embodiment, when the touch sensor comprises a fingerprint sensor, the operating mode is for emulating an input device such as a scroll wheel, a push button, a steering wheel, a joy stick, a pressure button, and a mouse.

Abstract: A system having a customized interface for providing user inputs to an electronic device and a method for configuring the system is disclosed. The system comprises a user interface that includes a finger sensor and a mechanical component, both for receiving user inputs. A customizable device interface couples the user interface to an electronic device, such as a mobile telephone or a digital camera. The device interface is configured to selectively map the output of the user interface to any number of programmed inputs used by the electronic device. Any combination of components that form the user interface can thus be selected and the device interface configured so that the outputs of the components are mapped to functions recognizable by application programs executing on the electronic device. In one embodiment, for example, the output of a finger sensor is used to control a mobile phone; in another embodiment the output of the finger sensor is used to control a digital camera.
