Abstract

A navigation arrangement for an electronic device that includes a screen, comprises: (i) a substantially transparent two dimensional capacitive position sensor that can be located over a screen of the device, and which can detect the position of an object with respect to the screen, and (ii) a two dimensional inductive position sensor for detecting the position of an intermediate coupler for example in the form of a pen or stylus with respect to the screen. The inductive position sensor comprises a transmit aerial for transmitting a signal, and a receive aerial for receiving the signal via the intermediate coupler so that the position of the intermediate coupler can be determined- The wiring of the inductive position sensor may be formed from a transparent conductor, or it may be arranged around the edge of the screen or behind the screen to enable the user to view the screen. Further forms of inductive position sensor, with or without capacitive position sensors, can enable a user to view a screen, for example by placing the inductive sensor tracks around the screen, or by connecting transparent conductors in parallel using low resistance busbars at the edge of the screen. Inductive position sensors may also be arranged to determine the position of the intermediate coupler in three directions, optionally in combination with other forms of sensor, and also to determine its orientation.
