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.

Embodiments described herein include an adaptive tracking system for spatial input devices that provides real-time tracking of spatial input devices for human-computer interaction (HCI) in a Spatial Operating Environment (SOE). The components of an SOE, which is analogous to an operating system, 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.
Embodiments of the systems and methods are provided in the context of the SOE described in detail below. Generally, FIG. 1A is a block diagram of a Spatial Operating Environment (SOE), under an embodiment. The SOE, which includes a gestural control system, or gesture-based control system, can alternatively be referred to as a Spatial User Interface (SUI) or a Spatial Interface (SI). Tracking as described herein includes the process of detecting and localizing the position of one or more spatial input devices. In the context of a SOE or other gestural interface, such tracking is used to determine when the user is trying to communicate with the system, to provide basic information needed for detecting and recognizing temporally extended gestures, and to allow for real-time control and feedback for interactions.
The adaptive tracking system of an embodiment provides real-time tracking of spatial input devices for human-computer interaction in a SOE that 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 functions and purpose of such a system are described in detail herein and in the Related Applications.
