Detecting, representing, and interpreting three-space input: gestural continuum subsuming freespace, proximal, and surface-contact modes
First Claim
1. A system comprising:
- a data funnel;
a gesture engine coupled to the data funnel;
a gestural event consumer;
wherein the data funnel is constructed to;
receive a plurality of tracking data streams from a plurality of types of object tracking devices streaming low-level tracking events for a same object in real time,temporally align the received low-level tracking events in real-time to generate a temporally-aligned multi-source tracking data stream that identifies a tracking event provided by two or more of the object tracking devices, andsemantically aggregate the temporally aligned low-level tracking events of multi-source tracking data stream,wherein the gesture engine is constructed to generate at least one gesture event from the semantically aggregated low-level tracking events, and distribute at least one gesture event to the gestural event consumer.

Abstract
Systems and methods for detecting, representing, and interpreting three-space input are described. Embodiments of the system, in the context of an SOE, process low-level data from a plurality of sources of spatial tracking data and analyze these semantically uncorrelated spatiotemporal data and generate high-level gestural events according to dynamically configurable implicit and explicit gesture descriptions. The events produced are suitable for consumption by interactive systems, and the embodiments provide one or more mechanisms for controlling and effecting event distribution to these consumers. The embodiments further provide to the consumers of its events a facility for transforming gestural events among arbitrary spatial and semantic frames of reference.
