This project will adapt biostereometrics imaging technology to create a universal, high-resolution, multi-purpose, three-dimensional computer interface. The comparison of data over time allows for movement (absolute change in position plus acceleration/deceleration data) to be monitored. Biostereometrics is the spatial or spatial-temporal analysis of biological form or function based on principles of analytic geometry. This technique defines the surface of an object by a finite set of three-dimensional coordinates generated from the analysis of pairs of two-dimensional images. An existing low resolution engineering/R&D system(330 x 192 pixels) capable of real-time imaging(30 frames/second) will be evaluated prior to the design of a high resolution system(754 x 488 pixels), and construction in Phase II. The active image area will comprise a cube I SO cm wide X 90 cm high x 90 cm deep(5' x 3' x 3'). Prototype software capable of following the absolute and serial position(s) for two fingers (thumb and index finger) on each hand will also be developed.Awardee's statement of the potential commercial applications of the research:A natural multi-parameter, multi-function computer interface based upon biostereometric imaging technology should see substantial commercial application at many levels and across most computer platforms.National Center for Research Resources (NCRR)
