3‐D natural interactive interface—using marker tracking from a single view

Abstract The proliferation of microcomputers and powerful single‐user minicomputers has created an urgent demand for effective man‐computer interface in three‐dimensional (3‐D) space. This paper presented an interface that is able to recognize finger movement by using an image processing from a single view. Two ring‐shaped markers are attached on the fingertip of an index finger and a thumb. Tracking the positions of two markers, six behaviors of the hand are detected. The detected behaviors to manipulate the object are as follows: catch the object, x translation, y translation, z translation, rotation in the horizontal plane, and rotation in the vertical plane. The image of the current hand and the object presented by wire‐frame is projected on CRT in real time. The operator is able to manipulate the object moving the hand within the view of the TV camera. Because of the foregoing six motions set equivalent to the motions exactly as done in daily life, an operator can maintain a natural interaction with a computer.
