HandSCAPE is an input device for digitizing field measurements to visualize the magnitude and direction of the resulting vectors with computer graphics. Using embedded orientation-sensing hardware, HandSCAPE captures relevant vector information on each linear measurement and transmits this data wirelessly to a remote computer in real time. The GeoSCAPE software analyzes this data, using trigonometry to define vector equations in Cartesian coordinates. Using certain heuristics, these vectors are applied by GeoSCAPE to recreate an archeological excavation rendered in computer graphics.
