Ever since Minority Report the idea of gesture-based computer interfaces has captured the imagination of techo junkies and sci-fi fans. Academic and industry labs have created a host of prototype gesture interfaces, ranging from room-sized systems with multiple cameras to detectors built into laptops screens.
MIT researchers have developed a system that could make gestural interfaces much more practical. Aside from a standard webcam, like those found in many new computers, the system uses only a single piece of hardware: a multicolored Lycra glove that could be manufactured for about a dollar. With the use of multipe colors on the glove it is able to read which part of the hand is being moved. Continue reading “Gesture-based computer interfaces”
