Abstract:
1. A system comprising: a video-based tracking system for locating real-world objects; a processor for determining the position and orientation of a user's view based on the location of the real-world objects; a display device for displaying an augmented reality image to the user, the augmented reality image being a view of real-world objects augmented with virtual objects; and an input device including a plurality of markers placed in a predetermined pattern in the real world, the input device being physically separate from the video-based tracking system, wherein the tracking system locates the input device and the processor determines its functionality based on the pattern of the markers such that a user can change the pattern of the markers by selectively making at least some of the markers visible and covering at least some of the markers thereby forming a new pattern, wherein the new pattern corresponds to a different programmed response to be performed by the tracking system, the markers emulating button functions such that at least one marker is augmented on the display device with a virtual object representing a menu of selectable options, the video-based tracking system identifying the new pattern and converting the new pattern into an associated function that is performed by the processor.
