Abstract:
A method for positioning a cursor using a handheld terminal, the handheld terminal, and an electronic device (300). The handheld terminal is provided with a camera (202). The method comprises: receiving a video image (21) that is currently being transmitted onto a display screen (100) of the electronic device (300) as a reference image (10), and photographing, via the camera (202), an acquired image (20) (S11), the acquired image (20) comprising part or all of the video image (21) that is currently being played on the display screen (100) of the electronic device (300); constructing, on the basis of the acquired image (20) and the reference image (10), a conversion matrix (S12); and converting, on the basis of the conversion matrix, a point in the acquired image (20) into a cursor position (12) on the display screen (100) (S13). The method uses image technology to achieve the function of positioning a cursor.
