Cursor control method and system and control device

Abstract

The invention discloses a cursor control method and system and a control device. The cursor control method includes the steps of before use, at the spatial position in front of a screen of a display device, determining corresponding boundary three-dimensional movement data when the control device controls a cursor to reach the boundary of the screen of the display device, during use, enabling the control device to sense three-dimensional movement data of the control device, judging whether the sensed three-dimensional movement data reach or exceed the boundary three-dimensional movement data or not, if the sensed three-dimensional movement data do not reach or exceed the boundary three-dimensional movement data, converting the sensed three-dimensional movement data into relative two-dimensional coordinates of the cursor, transmitting the two-dimensional coordinates to the display device, if the sensed three-dimensional movement data reach or exceed the boundary three-dimensional movement data, stopping transmitting data or transmitting cursor two-dimensional coordinate data obtained by the fact that cursor two-dimensional coordinates obtained by converting the three-dimensional movement data are perpendicularly mapped to the nearest boundary of the screen to the display device, and enabling the cursor to be kept in the boundary of the screen. By means of the technical scheme, the reality sense of sensitive operation can be brought to a user in a gunplay game. In cursor control systems of other kinds of application, the cursor control method can achieve one-to-one position corresponding between the control device and the cursor as well.

Description

technical field [0001] The invention relates to the field of graphics control, in particular to a cursor control method, system and control device. Background technique [0002] Currently in the research and development of the gun game product test, it is found that when the inertial gun points to the inside of the screen, the cursor is consistent with the direction of the gun, but when the gun points beyond the edge of the screen, the cursor will stay on the edge of the screen. If the pointing of the gun returns to the movement , the cursor will not be consistent with the pointing of the muzzle, but will start to move back from the screen boundary in the same way as the relative coordinates of the cursor. At this time, the cursor will maintain a distance difference from the inertial muzzle, and this distance difference is the gun At this time, there is no way to realize the realism of pointing and hitting when playing a gunfight game, that is, it is impossible to realize th...
