    Abstract: A touch screen assembly including a glass screen, LEDs, photo diodes, a transparent plastic frame surrounding the screen, and a light guide that guides light emitted by the LEDs to the photo diodes along light paths that go under the frame on one side, over the screen, and under the frame on the opposite side, and a processor operative to selectively activate LEDs and photo diodes, to identify location of an object touching the screen, based on amounts of light detected by activated photo diodes when light emitted by activated LEDs is blocked along its light path by the object, and to recognize the object touching the frame, based on amounts of light detected by activated photo diodes when light emitted by activated LEDs is absorbed along its light path by the object, thereby providing light-based touch sensitivity to the screen and to the frame.

    Abstract: A user input device, including a user input area, light emitters arranged along a first edge of the input area so as to be evenly spaced, light receivers arranged along a second edge of the input area, a curved lens arranged in front of the emitters, such that light emitted by each of the emitters is refracted as it enters the curved lens, and is again refracted as it exits the curved lens, resulting in unevenly spaced collimated light exiting the curved lens and crossing the input area, the collimated light being shifted laterally by a non-zero offset along a direction parallel to the first edge, the offset being a characteristic of the arrangement of that emitter vis-à-vis the curved lens, and a calculating unit for determining location of an object inserted into the input area from outputs of the receivers, based on the characteristic offsets of the emitters.
