Problems solved by technology

Although the problem of limited range of hand movement can be solved by increasing the acceleration factor of the cursor corresponding to the speed of hand movement, it will cause another problem that the positioning accuracy of the cursor becomes worse.

Embodiment Construction

[0031] The object of the present invention is to provide a method for controlling cursor movement on a display device through the movement of an external moving object tracking point in a small range. The selection control mode of the movement mode; capture the trajectory of the user's predetermined movement point in the external space and the predetermined action made by the movement point tracking unit, and start the cursor control process; based on the user's predetermined movement point in the external space Determine whether a reference point needs to be set, and if it is necessary to set a reference point, select the position of the moving point corresponding to the predetermined moving point in the external space coordinate system as the reference point for cursor control, and use the The selected reference point is the center, and a user coordinate system for cursor control is established; the current point corresponding to the user's predetermined motion point in the u...

Abstract

The invention relates to a cursor control method which comprises the following steps: setting a selection control mode of a first cursor moving way or a second cursor moving way in advance according to user's preference; tracking a moving point path, and initiating a cursor control processes according to the predetermined action; based on the predetermined action, determining whether a reference point is set or not, if yes, building a user coordinate system for cursor controlling through selecting a reference point and taking the selected reference point as a center; calculating the relative position between a current point and the reference point; and under the mode of the first cursor moving mode, performing cursor positioning for a cursor moving speed manner through maping the relative position, and under the mode of the secod cursor moving mode, performing cursor position adjustment on cursor offset distance through maping the relative position of the current moving point relative to the reference point.

Description

technical field [0001] The present invention relates to a method for controlling cursor movement of a display device used in the field of machine vision human-computer interaction, in particular to a method for controlling cursor movement on a display device through the movement of an external moving object tracking point in a small range and its use The method system. Background technique [0002] Currently, a large number of applications provide various user interfaces. Taking the traditional PC as an example, a large number of operations are completed by controlling the cursor with the mouse, which benefits from the convenience of mouse positioning. With the development of HCI human-computer interaction technology, new technologies are adopted and gradually replace the position of the mouse in human-computer interaction to achieve a more natural interactive non-contact remote control, such as the head mouse (headmouse) mentioned in US Patent US5367315A And eye mouse (ey...
