Adaptive tracking system for spatial input devices
First Claim
1. A system comprising:
- a plurality of tags affixed to a plurality of objects, wherein the plurality of tags include a plurality of features such that each tag comprises at least one feature;
a plurality of sensors, wherein a location of the plurality of sensors defines a spatial operating environment (SOE) that includes the plurality of objects, wherein the plurality of sensors detect the plurality of features; and
an adaptive tracking component (ATC) running on a processor, wherein the ATC receives from each sensor of the plurality of sensors feature data corresponding to each object of the plurality of objects detected by the respective sensor, wherein the ATC generates and maintains a coherent model of relationships between the plurality of objects and the SOE by integrating the feature data from the plurality of sensors.

Abstract
An adaptive tracking system for spatial input devices provides real-time tracking of spatial input devices for human-computer interaction in a Spatial Operating Environment (SOE). The components of an SOE include gestural input/output; network-based data representation, transit, and interchange; and spatially conformed display mesh. The SOE comprises a workspace occupied by one or more users, a set of screens which provide the users with visual feedback, and a gestural control system which translates user motions into command inputs. Users perform gestures with body parts and/or physical pointing devices, and the system translates those gestures into actions such as pointing, dragging, selecting, or other direct manipulations. The tracking system provides the requisite data for creating an immersive environment by maintaining a model of the spatial relationships between users, screens, pointing devices, and other physical objects within the workspace.
