  • Publication number: 20160119615
    Abstract: A technique to generate a three-dimensional (3D) data visualization from multi-dimensional data. A data set may be grouped into multiple groups based on a function. Data members of the groups may be mapped to respective 3D volumes via graphic elements. A value of the function for each data member may be mapped to at least one of the spatial display variables representing depth. A 3D data visualization including the 3D volumes may be generated.

  • Publication number: 20160104304
    Abstract: According to an example, in a method for displaying visual analytics of entity data, geographic locations of entities may be plotted as first pixel cells on a first region and as second pixel cells on a second region of a geographic map. A determination may be made that the first pixel cells have a higher degree of overlap with each other in the first region compared to the second pixel cells in the second region. The geographic map may be distorted to enlarge the first region and the first pixel cells may be arranged in the first region in a manner that prevents the first pixel cells from overlapping each other. A color value for each of the pixel cells may be determined from a multi-paired color map that represents two variables corresponding to the entities by color and the pixel cells may be caused to be displayed on the distorted geographic map according to the determined respective color values.

  • Patent number: 9269172
    Abstract: Example embodiments relate to providing pixel-based visualizations of time series data using nested helices. In example embodiments, helix portions in the time series data may be identified according to a measured time interval, where each of the helix portions represents the measured time interval in the time series data. A helical time period may then be determined and used as a helical revolution in a helical pixel representation. At this stage, the helical pixel representation may be generated using the helix portions, where proximate helix portions along a common line parallel to an axis of the helical pixel representation are chronologically separated by the helical time period.

  • Publication number: 20150288921
    Abstract: A system for providing a two-way interactive 3D experience includes a first video capture system configured to capture a first set of images of a first person in a first location, and a first display system in the first location. A second video capture system is configured to capture a second set of images of a second person in a second location. A second display system is in the second location. A two-way communication link is configured to deliver the first set of images to the second display system for display and deliver the second set of images to the first display system for display. The second display system is configured to generate a substantially life-sized 3D display of the first person based on the first set of images.

  • Publication number: 20150116329
    Abstract: A multi-attribute visualization is generated that includes non-overlapped cells that represent respective items. The cells are placed in the visualization according to geographic locations associated with the items, and the cells being assigned visual indicators to represent a first attribute of the items. The cells are arranged in clusters in the visualization, where a size of a particular one of the clusters indicates a second attribute representing a number of cases associated with a corresponding one of the items. Multiple coordinated views of the cells are presented in the visualization, the multiple views corresponding to respective different time intervals.

  • Publication number: 20140035893
    Abstract: A display system includes a plurality of individual display devices to collectively generate an image on a display surface. At least one camera captures at least one image of the image on the display surface and captures at least one image of an object positioned near the display surface. A controller automatically adjusts a color of an object appearing in the image on the display surface based on the at least one image of an object.
