Wang imagines that video game players, designers, and engineers will someday use his system to easily maneuver 3-D models of products and large structures. Wang's gloves are already nabbing attention, not just for their bright appearance, but because Lycra is cheap to manufacture and can stretch to fit all hand sizes. The system itself can quickly adjust to the shape of a wearer's hand. The glove user presses his hand against an 8.5-by-11-inch sheet of paper on a flat surface in front of a webcam, and voila, the system has learned. Wang hopes that in time, people will apply his technology to bigger pieces of clothing, like shirts, in order to aid digital animation or assess athletic performance.
