An Inexpensive 6D Motion Tracking System for Posturography

Short-Term Motion Tracking Using Inexpensive Sensors

Assessment of Visual Reliance in Balance Control: An Inexpensive Extension of the Static Posturography

Ability of humans to maintain balance in an upright stance and during movement activities is one of the most natural skills affecting everyday life. This ability progressively deteriorates with increasing age, and balance impairment, often aggravated by age-related diseases, can result in falls that adversely impact the quality of life. Falls represent serious problems of health concern associa...

Inexpensive Wireless Telemetry for Animal Tracking

Master of Electrical Engineering Program Cornell University Design Project Report Project Title: Inexpensive Wireless Telemetry for Animal Tracking Author: Christopher Yeou-Hwa Chau Abstract: This project explored the feasibility of creating a cost-effective transmitterreceiver pair to replace commercially available 150 MHz devices used in animal telemetry. Distance measurements of test circuit...

Coarse, Inexpensive, Infrared Tracking for Wearable Computing

We present a novel, inexpensive, coarse tracking system that determines a person’s approximate 2D location and 1D head orientation in an indoor environment. While this coarse tracking cannot support precise registration of overlaid material, it can be used to drive user interfaces that can adapt to the quality of tracking available. Our approach uses a set of strong infrared beacons, each of wh...

Shape and Motion Carving in 6D

The motion of a non-rigid scene over time imposes more constraints on its structure than those derived from images at a single time instant alone. An algorithm is presented for simultaneously recovering dense scene shape and scene flow (i.e., the instantaneous 3D motion at every point in the scene). The algorithm operates by carving away hexels, or points in the 6D space of all possible shapes ...
