| 20090278808 | Method for controlling pointing device, pointing device and computer-readable storage medium - An input mode is controlled in such a manner that a one-point input mode is set as an initial state, the one-point input mode is changed to a two-point input mode when both the first input point and the second input point are turned on and the two-point input mode is changed back to the one-point input mode when both the first input point and the second input point are turned off. A coordinate position of an indicated point is determined on the basis of an absolute position of the first input point in the one-point input mode and on the basis of a relative positional relationship between the first input point and the second input point in the two-point input mode. | 11-12-2009 |
