Abstract
The invention discloses a position control method and device and a remote orientating system for a cursor. One side where a display surface of display equipment is located is provided with a plurality of signal sources, at least two signal sources are selected as reference signal sources, and images containing reference signals of the reference signal sources are collected. When the included angle between the straight line where coordinates of any two reference signals are located and a preset reference line does not coincide with a reference included angle or a coordinate relationship among the reference signals does not coincide with a reference coordinate relationship, the coordinates of the reference signals are corrected, and then the position of the cursor is controlled according to the coordinates of any one corrected reference signal. When orientating equipment rotates, the coordinates of the reference signals needing to be obtained are corrected and sent to a host computer, and the host computer controls the position of the cursor according to the coordinates of the reference signals. It is avoided that when the orientating equipment rotates, mistaken coordinates are sent to the host computer, so that the position of the cursor is not accurate.
