An overlay is provided for an electronic device such as a cellular telephone, PDA, laptop, slate etc that includes a sensor, preferably an inductive sensor, and electronics that operate in response to input from the sensor. The overlay comprises an identification device, e.g. an RFID tag, and an intermediate coupler that is preferably electrically passive, and especially a passive resonant circuit formed from an inductor and a capacitor. The intermediate coupler is associated with a manually operable input device such as a key, button, slider, or knob that can be manually operated by a user, so that operation of the input device will change a property of the coupling device such, as its resonant frequency or position on the sensor, which change is sensed by the sensor in order to actuate a function of the device. The overlay enables a user to customise his device for various applications such as communication, games, music or audio visual, and since the overlay has no active components, it can be made for very low cost. A peripheral docking station may also communicate with the device inductively, and charge its batteries. |
