Abstract: A method for controlling movement of a computer display cursor based on a point-of-aim of a pointing device within an interaction region includes projecting an image of a computer display to create the interaction region. At least one calibration point having a predetermined relation to the interaction region is established. A pointing line is directed to substantially pass through the calibration point while measuring a position of and an orientation of the pointing device. The pointing line has a predetermined relationship to the pointing device. Movement of the cursor is controlled within the interaction region using measurements of the position of and the orientation of the pointing device.

Abstract: A voltage-programmed display system allows measurement of effects on pixels in a panel that includes both active pixels and reference pixels coupled to a supply line and a programming line. The reference pixels are controlled so that they are not subject to substantial changes due to aging and operating conditions over time. A readout circuit is coupled to the active pixels and the reference pixels for reading at least one of current, voltage or charge from the pixels when they are supplied with known input signals. The readout circuit is subject to changes due to aging and operating conditions over time, but the readout values from the reference pixels are used to adjust the readout values from the active pixels to compensate for the unwanted effects.

Abstract: Disclosed is a method and system of gesture recognition in a touch display device, which is able to predetermine gesture inputs possibly to be made by a user prior to the completion of the user's touch input, and enable a display unit to display all possible similar gesture inputs so as to provide an instruction (or navigation guidance) for the user. Thus, when using a large-sized touch display device, the user does not have to perform touch operations widely throughout the screen of the display device, because the system can recognize the similar gesture inputs in advance, which renders it easier for the user to operate on the touch display device, thereby obtaining a better user experience.

Light transmittance and picture contrast of the display panel can be improved when the high grayscale image is displayed.

The components of an SOE include gestural input/output; network-based data representation, transit, and interchange; and spatially conformed display mesh. The SOE comprises a workspace occupied by one or more users, a set of screens which provide the users with visual feedback, and a gestural control system which translates user motions into command inputs. Users perform gestures with body parts and/or physical pointing devices, and the system translates those gestures into actions such as pointing, dragging, selecting, or other direct manipulations. The tracking system provides the requisite data for creating an immersive environment by maintaining a model of the spatial relationships between users, screens, pointing devices, and other physical objects within the workspace.

Abstract: Approaches presented herein provide for user interface selection through an intercept point defined by a touch sensitive bezel. More specifically, a touch sensitive bezel, in a device having a display at least partially surrounded by the touch sensitive bezel, senses a horizontal position and a vertical position on the display from two locations on the bezel touched by a user. An intersection on the display where the horizontal position and the vertical position cross is determined and can be marked on the display. A user may slide his/her fingers along the touch sensitive bezel to move the intersection around the display. A user may perform an additional action to confirm a selection of an item located at the intersection. The touch sensitive bezel can also be used to control interface selection on a display of a second device by mapping the horizontal and vertical positions to the second device display.
