1. An electronic device comprising:
a display screen, wherein the display screen comprises:
a first edge;
a second edge parallel to the first edge, wherein the first edge and the second edge are parallel to a first direction;
a third edge; and
a fourth edge parallel to the third edge, wherein the third edge and the fourth edge are parallel to a second direction, and wherein the first direction is perpendicular to the second direction;
at least two ultra-wide band (UWB) base stations, wherein the at least two UWB base stations are located at different positions at a front or a back of the display screen, and configured wherein all or part of a perpendicular projection from each of the at least two UWB base stations is located adjacent to at least one edge of the display screen;
one or more computer programs; and
one or more processors configured to execute the one or more computer programs to cause the electronic device to:
display a cursor on the display screen, wherein the cursor is moveable on the display screen in response to movement of a mobile device;
receive a cursor indication message from the mobile device, wherein the cursor indication message indicates a movement direction of the cursor on the display screen;
control the cursor to move in the first direction or the second direction in response to the cursor indication message; and
control the cursor to stop moving in the first direction 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 the third edge and the fourth edge.
