A pointing apparatus and method and a pointer display apparatus and method using a virtual region which generate a virtual region corresponding to a detected display region, convert coordinates of a location, and display a pointer at the converted coordinates. The pointing device includes a region detector detecting a display region, which displays a pointer, using at least one received signal; a virtual region generator generating the virtual region corresponding to the display region and having an aspect ratio equal to that of the display region; a coordinate converter converting coordinates of a location, which is pointed at by the pointing device, in the virtual region into ratios of the coordinates of the location to a size of the virtual region; and a coordinate ratio transmitter transmitting the ratios.
