CURSOR-CONTROL DEVICES AND METHODS THEREOF

摘要

A cursor-control device is provided for an electrical device having a display unit. The cursor-control device includes a button, an image-capture unit and a processing unit. The image-capture unit obtains a screen from the display unit. The processing unit determines cursor coordinates according to the screen, detects the number of times the button has been pressed and released, and determines whether to transmit a double-click signal to the electrical device according to the number of times of the button switching. When the button becomes pressed or released, the number of times of the button switching increases by one. Also, when the number of times of the button switching reaches two, the processing unit stores the cursor coordinates.
