| 摘要 | A method for controlling a computer display cursor in an interaction region includes projecting an image of the computer display to create the interaction region. A distance is established between a first point and a second point. The first point has a predetermined relation to the projection device, and the second point has a predetermined relation to the interaction region. At least one of an orientation and a position of a pointing line is measured. The pointing line has a predetermined relation to a pointing device. The established distance and the at least one of measured position and orientation are used to control the cursor position on the interaction region. | ||
