Abstract: In one embodiment, improved techniques are provided for identifying and/or highlighting a graphic element. A multi-dimensional data structure corresponding to a visual representation of information may be created, wherein, for each active point in the visual representation of information, the multi-dimensional data structure has a corresponding location that stores a globally unique identifier (GUID) that indicates one or more graphic elements present at that point in the visual representation. A selection from a user of a selected point in the visual representation of information may be received. A location of the selected point may be used as an index into the multi-dimensional data structure to determine a particular location in the multi-dimensional data structure that coincides with the selected point. A particular GUID may be retrieved from the particular location and used to identify one or more graphic elements.

Abstract: In one embodiment, a special paper plot (referred to herein as a dynamic plot) for which corresponding metadata is maintained is printed. A mobile appliance obtains corresponding metadata for the dynamic plot. A camera of the mobile appliance computes an image of the dynamic plot. A position of the camera of the mobile appliance with respect to the dynamic plot is calculated from the image of the dynamic plot. Using the calculated position, information or icons are overlaid at particular locations in the image captured by the camera of the dynamic plot. The image captured by the camera of the dynamic with the overlaid information or icons is then displayed on a display screen of the mobile appliance. A user may add annotations beyond what is printed on the dynamic plot. This information may subsequently be shared with other users involved in the project.
