Robert Wang, a graduate student in the Computer Science and Artificial Intelligence Laboratory at MIT, and Jovan Popovic, MIT associate professor of electrical engineering and computer science, developed a budget-friendly gesture-based computing system that requires just a web camera and a multi-colored Lycra glove, which can be manufactured for about a dollar.
The new system works in 3D and interprets movements made with the gloved hand into corresponding motions made with a 3D model on screen with no lag time. Applying the technology to video games, for example, would allow players to pick up objects and wield weapons.
The system is a step up from other low-cost gestural interfaces, which work in 2-D with reflective or colored tape attached to the fingertips. According to Wang on the MIT News site, "You're only getting the fingertips; you don't even know which fingertip [the tape] is corresponding to."
