Proximity Toolkit


The Proximity Toolkit is a catalyst for developing applications that make use of spatial information, and relations between objects in space. The toolkit is meant to deliver proximity data to applications during runtime which can be utilized as program input. It is designed to collect input from a number of potential input sources, then fuse the raw data into a set of generalized high-level presence objects that hide low-level implementation details.

Currently, our primary source of input is a Vicon motion tracking system, which provides highly accurate tracking on objects that are tagged with a combination of several infrared-reflective markers. In the most recent version 2.0 of the toolkit we also added support for tracking through Microsoft Kinect depth-sensing cameras.
