    Abstract: The pointing device mainly contains a fingerprint sensor capable of capturing continuous images of the fingerprint of a user's finger when the finger is moved across a sensing area of the fingerprint sensor. From these continuous images, the pointing device is able to calculate the direction and speed of the movement of the finger. These pieces of information are then passed to a host computer system, which in turn adjusts the position of a cursor shown on a display device.

    Abstract: The invention provides mechanical devices to enhance the input process for touch screen devices. Fader tracks with or without fader caps, rotary and fixed knobs, and joysticks may be removably adhered to a touch screen and used to emulate their respective functions, using software interpretation of the touch detections provoked by the devices to carry out the emulations. The devices are inexpensive and simple, and the touch screen and associated software provide the function and feel of electromechanical controllers that are far more expensive and difficult to connect and maintain. The devices may be provided as components on a crack-and-peel sheet. For fixed knobs, the software application accepts initial inputs and determines the location on the touch screen, and also interprets the geometry of the input strokes as commands for selected controller emulations, such as joystick, fader, knob, or mouse.

    Abstract: An image display device has a touchpad and an image display area that is composed of a plurality of sub-areas obtained by dividing the image display area into a two-dimensional array. A sensor surface of the touchpad is positionally correlated to the image display area. In response to a touch on the touchpad, the image display device specifies one or more of the sub-areas and adjusts the brightness of the specified sub-areas. In addition, the image display device specifies a different portion of the display image in response to a different user operation, such as a user operation of touching the touchpad with his finger and moving the finger across the touchpad, two successive user operations, or a user operation made at a specific tracing speed.

    Abstract: A symmetric touch screen switch system in which both the touch side and panelside transparent electrodes are comprised of carbon nanotube thin films is provided. The fabrication of various carbon nanotube enabled components and the assembly of a working prototype touch switch using those components is described. Various embodiments provide for a larger range of resistance and optical transparency for the both the electrodes, higher flexibility due to the excellent mechanical properties of carbon nanotubes. Certain embodiments of the symmetric, CNT-CNT touch switch achieve excellent optical transparency (<3% absorption loss due to CNT films) and a robust touch switching characteristics in an electrical test.

    Abstract: A system detects when a user's finger is near a key on a touch screen. When the user's finger is near the key, the touch screen may begin to vibrate. The vibrations may increase in frequency and/or intensity as the user's finger approaches the key. The vibrations may decrease in frequency and/or intensity as the user's finger moves away from the key.

    Abstract: A display system detects a position of a viewer relative to the display device, and adjusts the presentation of information at the display device based on this relative position. The adjustment of the presentation may be to increase or decrease the intrusiveness of the displayed information. In a commercial billboard display, the presentation is adjusted to potentially increase a viewer's awareness of key terms or phrases; in a multi-purpose consumer device, such as a vanity mirror with an integral display, the presentation is adjusted to minimize the intrusion of the information relative to the primary purpose of the device.
