Human bodies are very good heat sources with peak emission wavelength of about 9?m. We use pyroelectric detectors that are differential in nature to detect human motion by their heat emissions. Coded Fresnel lens arrays create boundaries in space whi

A network of common pyroelectric motion sensors that can track and identify human targets has been developed using low-cost, commercially available components. Significantly cheaper than deploying infrared imaging systems and considerably more advanc

We design and calibrate an efficient human detection system, capable of detecting and tracking a single person while minimizing the number of required sensors. Our infrared detectors have a 2 meter range and a 250ms rise/fall time. We sample their si

The Argus project uses an array of computers and cameras as a means of investigating telepresence and real-time three-dimensional imaging. In this paper we will briefly discuss telepresence from an information flow and visualization perspective. The

We recently implemented a heterogeneous network of infrared motion detectors and an infrared camera for the detection, localization, tracking, and identification of human targets. The network integrates dense deployments of low cost motion sensors fo

We design and develop a low-cost pyroelectric detector- based IR motion-tracking system. We study the characteristics of the detector and the Fresnel lenses that are used to modulate the visibility of the detectors. We build sensor clusters in differ

We describe a Fresnel lens based motion tracking system implemented using pyroelectric detectors. Lens arrays are used to modulate the visibility of the sensors and with a combination of many such arrays on multiple sensors, human motion can be track
