Publication number: 20080231609Abstract: Data elements stored in a computing system and associated with a physical object are reassociated with the same or another physical object. An identifying characteristic presented by the physical object, such as a reflective pattern applied to the object, is detected when the object is positioned adjacent to the interactive display surface. Images or other files associated with the identifying characteristic are accessed and displayed on the interactive display surface. A gesture by a user adjacent to the interactive display surface is detected to reassociate a selected representation. For example, the user can change where the selected element fits in a sequence of data elements, or reassociate the selected element with a second object placed on the interactive display surface. In a networked environment, the reassociated element can be stored on a server and subsequently accessed from a different interactive surface via the network using the second physical object.Type: ApplicationFiled: April 14, 2008Publication date: September 25, 2008Applicant: Microsoft CorporationInventors: Joel P.

Publication number: 20080231611Abstract: An interactive table has a display surface on which a physical object is disposed. A camera within the interactive table responds to infrared (IR) light reflected from the physical object enabling a location of the physical object on the display surface to be determined, so that the physical object appear part of a virtual environment displayed thereon. The physical object can be passive or active. An active object performs an active function, e.g., it can be self-propelled to move about on the display surface, or emit light or sound, or vibrate. The active object can be controlled by a user or the processor. The interactive table can project an image through a physical object on the display surface so the image appears part of the object. A virtual entity is preferably displayed at a position (and a size) to avoid visually interference with any physical object on the display surface.Type: ApplicationFiled: April 25, 2008Publication date: September 25, 2008Applicant: Microsoft CorporationInventors: Steven Bathiche, David Joshua Kurlander, Andrew D.

Publication number: 20080231617Abstract: To provide a display device in which reliability of a driver circuit can be improved by suppressing shift of the threshold voltage of a TFT. The minimum power supply voltage that is optimal for driving a transistor used in the driver circuit is found by actually changing voltage applied to a gate of the transistor. Specifically, voltage that is output from an output circuit included in the driver circuit when a value of power supply voltage applied to a shift register is changed is monitored. Then, a value of the power supply voltage is found such that a value of the voltage output from the output circuit satisfies a value enough to operate a pixel portion, and the driver circuit is operated using the power supply voltage.Type: ApplicationFiled: March 13, 2008Publication date: September 25, 2008Inventors: Hiroyuki Miyake, Atsushi Umezaki
