  • Patent number: 7259751
    Abstract: A method for evaluating an input system interfacing a human user with an electronic device uses empirically determined bi-action times for users to perform a second input action (e.g., pressing a second key) immediately after performing a first input action (e.g., pressing a first key). The bi-action times (or, more generally, n-action times) are used together with a selected interface map which associates input actions (e.g., pressing keys) to corresponding signifiers (e.g., characters) to calculate a peak expert input rate for the input system. One or more optimized interface maps can be found by combining the evaluation method with any of various optimization strategies. For example, one method for optimizing the input system repeatedly changes the interface map and recalculates the peak expert input rate, while another optimization method calculates peak expert input rates for multiple interface maps in parallel.

  • Patent number: 7259752
    Abstract: A computer-implemented method and system for erasing and editing an electronic document. A goal for computing devices that support the use of a stylus that can record handwriting strokes and present them in an electronic document is to present electronic ink that behaves similar to real ink from a pen. The nature of the electronic document and the electronic ink makes it difficult to edit the ink as one would with traditional pen and paper. However, an editing module accompanying the computing device can provide a user with functionality that facilitates the editing of electronic ink. Specifically, the editing module cna provide a feedback mechanisms, such as highlighting or shading, that indicates to the user which portions of handwriting strokes are selected for editing. Additionally, the editing module can recognize certain gestures and determine which handwriting strokes to apply the editing gesture to.

  • Patent number: 7259754
    Abstract: When a user indicates a point on a display screen of a computer using a pen sensor, first the display screen is divided into a plurality of areas and the areas are displayed by mutually different colors or brightnesses. The plurality of colors or brightnesses displayed are scanned by the pen sensor and the colors or brightnesses detected by the light receiver to judge in which area the indicated point is located. Next, the judged area is further divided into a plurality of areas which are displayed by mutually different colors or brightnesses. Next, a routine similar to the above is successively repeated to narrow down the area in which the point indicated by the pen sensor is located and finally determine the position of the point, that is, the XY coordinates on the display screen.

Accordingly, difficulty in setting a predetermined threshold to a single value can be overcome. In addition, even a very slight motion can be accurately detected without being influenced by gravity and offsets. Moreover, it can be accurately determined whether a user's two- or three-dimensional motion is an effective motion for selecting information and which motion unit among at least two motion units has generated the effective motion, so that a high correct recognition rate for information and high reliability can be achieved, and a user is allowed to easily select information.

  • Patent number: 7259757
    Abstract: An object is to provide an image signal processing device capable of converting digital image signals into analog image signals using a circuit of small scale. Addition high-order bit pixel data is generated by adding, to high-order bit pixel data comprising an high-order consecutive bits of input pixel data, a value corresponding to the least significant bit digit of the high-order bit pixel data. In a prescribed period, during a time period corresponding to a value of low-order bit pixel data comprising low-order consecutive bits of the input pixel data, the addition high-order bit pixel data is taken to be the data for D/A conversion, and in other period, the high-order bit pixel data is taken to be the data for D/A conversion. By means of this configuration, even when the resolution of a D/A converter is lower than the resolution required by the input pixel data, the resolution of the image ultimately viewed during the prescribed period is equivalent to the resolution required by the input pixel data.

  • Patent number: 7259758
    Abstract: An interactive display system wherein a projector receives signals from a graphics source in a manner that reduces latency in images projected onto a display surface. The signals include a pixel clock signal, pixel attribute signals, and synchronization signals. The pixel clock signal is used to clock sample and hold registers at the projector to preserve the pixel attribute signals received from the graphics source. The preserved pixel attribute signals, along with position signals corresponding to the synchronization signals, are presented directly to the projector. Parameters of the projector are known, and all gain, gamma correction, and scaling are performed before the signals are provided by the graphics source. Thus, it is unnecessary to digitize, store, adjust, or otherwise process pixel attribute signals at the projector, which simplifies processing of the graphics signals and reduces latency in generating the image in response to an input on the display surface.

  • Patent number: 7259760
    Abstract: A texture projection is generated from a plurality of initial polygonal curved surfaces. Specifically, each of the initial polygonal curved surfaces are divided to form a plurality of second-generation polygonal curved surfaces. Each second-generation polygonal curved surface is then divided to form a third-generation polygonal curved surface. In one embodiment of the present invention, each polygonal curved surface of the same generation has the same area. The texture projection formed using polygonal curved surfaces is more efficient than conventional texture projection because each facet of the texture projection formed using polygonal curved surfaces maps to a spherical area.

  • Patent number: 7259764
    Abstract: The present invention includes a method and apparatus for representing joint rotations of character models that eliminates the artifacts imposed by the ambiguities inherent in four angle rotations. An embodiment of the invention transforms joint angles from their original four angle representations into a set of defrobulated angles that provides the least confusion between position and twist information. Manipulating the character model using the set of defrobulated angles eliminates the angular discontinuities responsible visual “popping” and other visual discontinuities. In an embodiment, an animator specifies a pose using joint angles in their four angle Euler form. The joint angles of the pose is transformed to the defrobulated form. The defrobulated joint angles are weighted and applied to the points of the character model. The weighted sum of the defrobulated angles for each point are then converted back to an Euler angle form to pose the point.

  • Patent number: 7259765
    Abstract: A system for processing graphics data for a stream of graphics primitives, such as triangles. The system has a plurality of memories each for storing an index of the primitive. A controller selects a memory to store the index and assigns a thread id to the index, the thread id indicating in which memory the index is stored. The thread id is stored in both a HEAD ID FIFO and a DATA ID FIFO, to maintain the order of the primitives during processing. A first multiplexer accesses a selected memory based on a thread id provided by the HEAD ID FIFO and a second multiplexer accesses a selected memory based on a thread id provided by the DATA ID FIFO. For each of the vertices of the graphics primitive, the first multiplexer provides a pointer for accessing coordinate information and the second multiplexer provides a pointer for accessing attribute information.

  • Patent number: 7259767
    Abstract: The present invention relates to a method and system for segmenting texture of multi-dimensional data indicative of a characteristic of an object. Received multi-dimensional data are transformed into second multi-dimensional data within a Stockwell domain based upon a polar S-transform of the multi-dimensional data. Principal component analysis is then applied to the second multi-dimensional data for generating texture data characterizing texture around each data point of the multi-dimensional data. Using a classification process the data points of the multi-dimensional data are partitioned into clusters based on the texture data. Finally, a texture map is produced based on the partitioned data points. The present invention provides image texture segmentation based on the polar S-transform having substantially reduced redundancy while keeping maximal data variation.
