Abstract: A method for controlling movement of a cursor on an electronic device, a mobile device, and. an electronic device are provided. The electronic device includes: a processor; a memory; a display screen, where the display screen includes a first edge, a second edge, a third edge, and a fourth edge, the first edge is parallel to the second edge, the third edge is parallel to the-fourth edge, the first edge and the second edge are parallel to a first direction, the third edge and the fourth edge are parallel to a second direction, the first direction is perpendicular to the second direction, and a cursor on the display screen moves on the display screen with the mobile device; at least two UWB base stations; and a computer program, where when the computer program is executed by the processor, the electronic device is enabled to perform the following steps: when the cursor moves to the third edge or the fourth edge, and an intersection point between a straight line in a direction to which the mobile device points and a plane on which the display screen is located is not between a straight line on which the third edge lies and a straight line on which the fourth edge lies, the cursor no longer moves in the first direction with the mobile device. The electronic device resolves a problem of out-of-focus between the mobile device and the cursor on the display screen.

Abstract: A mobile device communicates wirelessly with an annotation device and a to-be-annotated electronic device. The mobile device includes a processor, a memory, a UWB tag, a direction sensor, and a computer program stored in the memory, and when the computer program executed by the processor, the mobile device is enabled to perform: receiving a first input after the mobile device moves to a location of the electronic device; recording a location of the mobile device in response to the first input, where the location of the mobile device is the location of the electronic device; and popping up a first control window for the electronic device after the mobile device moves to another location and points to the electronic device. According to this application, the mobile device can control, by using the annotation device, an electronic device on which no UWB chip is installed.
