Abstract

The embodiment of the present invention discloses a method for controlling a cursor, including: obtaining at least one effective image, wherein the effective image contains a laser spot; based on the at least one effective image, determining that the cursor of the terminal is currently The position of the laser spot; based on the position, sending a control message to the terminal, where the control message is used to instruct the terminal to control the movement of the cursor until it coincides with the laser spot. The embodiment of the invention also discloses a cursor control device and an input device.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method, device and input device for controlling a cursor. Background technique [0002] With the development of electronic equipment screen display technology, especially the wide application of touch screen display, no keyboard and no mouse operation has become the development trend of various electronic equipment, bringing a broad market for new terminal information input technology prospect. [0003] In the traditional terminal information input technology, the photoelectric mouse technology facilitates the information input operation to a certain extent, but its control on the cursor is relative, relying on the reflection of light on the reflective surface to determine the movement of the mouse, and then to determine the position of the cursor. Adjustment, unable to get rid of the dependence on the reflective surface has caused inconvenience in its use, and the accurac...
