Abstract :
The earliest bit-mapped graphical computers have progressed to bring real-time 3D rendering and digital video to the desktop, but the common physical interface remains unchanged from the first workstations. As a result, many applications, such as modeling or navigating in virtual worlds, are often limited not by processing speed but by the users´ difficulty in conveying desired actions to the computer. We outline the theory and implementation of low-frequency electric fields as sensing techniques, then present a range of applications developed for interacting with computer graphics
