Abstract: A calling and display unit displays the image of a function calling icon (FCI) on at least one of the four corners of a screen of a touch panel. An icon calling unit calls function activation icons (FAI) in correspondence to a touch manipulation on the FCI. A function display unit displays the images of the called FAIs so as to be arranged on at least one of the four sides of the screen, which communicates with one of the four corners where the FCI is located. Therefore, the proportion in which the images of the displayed FAIs obstruct a display image displayed on the screen can be minimized. In this way, a data processing device minimizes the proportion in which the images of the FAIs displayed on the touch panel obstruct the display image.

Abstract: A keyboard includes an upper frame, a main body, a lower frame, and an adjustment mechanism. The two frames cooperate with each other to sandwich the main body. The lower frame includes a bottom plate defining a though hole. The adjustment mechanism is configured to adjust an inclined angle of the keyboard, and includes an adjustment member, a supporting member, a driving member and a position stopper.

The position stopper resists the supporting member to secure the supporting member when the adjustment member is free.

Abstract: A device-mounted infrared (IR) camera and a hybrid visible/IR light projector may be used to project visible animation sequences along with invisible (to the naked eye) tracking signals, (e.g. a near IR fiducial marker). A software (or firmware) platform (either on the handheld device or to which the device communicates) may track multiple, independent projected images in relation to one another using the tracking signals when projected in the near-IR spectrum. The resulting system allows a broad range of new interaction scenarios for multiple handheld projectors being used in any environment with adequate lighting conditions without requiring the environment to be instrumented in any way.

Abstract: A system and method for controlling a user interface display that de-emphasizes a background image of a physical display. The system and method draws a pattern, preferably a checkered pattern, of black and transparent pixels over the background image.

Although in the preferred embodiment, the checkered pattern alternates pixels between black and transparent, any pattern that drives less than substantially all of the pixels to black is suitable.
