Abstract: An optical navigation device and method for performing optical navigation uses an optically transparent flexible film, which is positioned over a sensor that includes an image sensor array, to allow the image sensor array to receive imaging light from a target surface that is produced in response to illumination light emitted into the target surface from a light source. The imaging light from the target surface is received at the image sensor array of the sensor to capture frames of image data of the target surface. The frames of image data are then compared to estimate relative displacements between the target surface and the image sensor array.

Abstract: Methods and apparatus provide for a touch sensitive display, in which a transparent layer is disposed over a display layer; light is directed to propagate into and/or through the transparent layer; scattered light is measured in response to an object touching a surface the transparent layer and disturbing the propagation of the light therethrough; and one or more positions at which the object touches the transparent layer are computed based on signals obtained by the step of measuring the scattered light.

Abstract: There is provided an electronic device having a mutual capacitance touchscreen or touchpad having combined finger navigation and active stylus navigation and character entry capabilities. According to one such embodiment, first and second pluralities of sense and drive electrodes are disposed in or on at least one substrate, and form an array configured to permit a first location corresponding to a finger or a second location corresponding to an active stylus to be detected thereby. The drive electrodes in the array are configured to operate as drive electrodes when the touchscreen or touchpad operates in a first finger touch mode, and to operate as additional sense electrodes when the touchscreen or touchpad operates in a second active stylus mode.

Abstract: A screen system includes a display, three or more sensors, a processor connected to the display and the three or more sensors, and a clock connected to the processor. When a position on a display is selected by a stylus that includes one or more emitters, the one or more emitters each emit a pulse or a series of pulses. Each sensor generates a receive message when the sensors receive a pulse. Each receive message includes an identifier identifying which sensor transmitted the receive message. The processor then determines the location of the emitter or emitters in the stylus and the position on the display using the sensor identifiers and a respective time associated with each receive message.
