| 20090046059 | FINGER POINTING APPARATUS - A finger pointing apparatus is disclosed. In one aspect the finger pointing apparatus includes at least one pressure sensor fixed on a hand for triggering a corresponding electromagnetic wave transmitter to transmit electromagnetic wave when pressure is produced by a finger contacting an external object. In another aspect, the finger pointing apparatus includes at least one electromagnetic wave transmitter connected with a corresponding pressure sensor and fixed on the hand for transmitting electromagnetic wave to all electromagnetic wave receivers when pressure is detected by the pressure sensor. In one aspect, the finger pointing apparatus includes at least two electromagnetic wave receivers arranged at fixed positions with respect to each other for receiving electromagnetic wave from the at least one electromagnetic wave transmitter and transmitting received electromagnetic wave to a microprocessor. In another aspect, the finger pointing apparatus includes a microprocessor for receiving electromagnetic wave from the electromagnetic wave receivers, calculating coordinate values of a position pressed by the finger from electromagnetic wave from different electromagnetic wave receivers and outputting the coordinate values. | 02-19-2009 |
| 20100090983 | Techniques for Creating A Virtual Touchscreen - A technique for creating a virtual touchscreen includes capturing, with a first infrared camera, a first reflection from an object that is at a known position adjacent a surface associated with a device. A second reflection from the object (at the known position) is captured with a second infrared camera. The first and second reflections are correlated with the known position to provide a two-dimensional position for the object that is calibrated with respect to the surface. | 04-15-2010 |
| 20100103141 | Techniques for Controlling Operation of a Device with a Virtual Touchscreen - A technique for controlling operation of a device with a virtual touchscreen includes defining an area of a surface, associated with the device, as the virtual touchscreen. An operation within the device is then initiated based on activity within the virtual touchscreen. An overlay may be provided, on a display screen of the device, to indicate a location of the virtual touchscreen with respect to, for example, a keyboard of the device. | 04-29-2010 |
| 20100134409 | THREE-DIMENSIONAL USER INTERFACE - The instant invention provides an apparatus, method and program storage device enabling a three-dimensional user interface for the movement of objects rendered upon a display device in a more realistic and intuitive manner. A Z distance is set whereupon a user crossing the Z distance is enabled to select an object, i.e. pick it up. As the user breaks the Z distance again, the object selected will move with the user's hand. As the user breaks the Z distance once more, the object will be released, i.e. dropped into a new position. | 06-03-2010 |
| 20100134421 | COMBINED TAP SEQUENCE AND CAMERA BASED USER INTERFACE - The invention includes a method, apparatus, and program storage device for providing a combined tap sequence and camera based user interface. The invention provides, among other features, an apparatus comprising: an accelerometer; a laser light generating module; wherein the laser light generating module provides a plane of laser light over a surface coupled to the accelerometer; at least one camera; at least one processor; and a memory; wherein the memory stores instructions, executable by the at least one processor, enabling the apparatus to ascertain an occurrence of an input event utilizing inputs from the accelerometer and a location of the input event utilizing inputs from the at least one camera. | 06-03-2010 |
