A system and method for displaying tracked objects on a display is disclosed The method includes writing current location and a number of previous locations of the object with pixel values having non-zero overlay data. The system writes an ordered set of codes into the pixel values for the current location and indicates the set to a driver. The driver uses the overlay data displaying the current and several previous object locations sequentially in order of the set. The displayed locations may be displayed by unmasking the overlay data. The codes may be index values in the pixel values indicating corresponding entries in a pixel interpretation table. A driver may modify mask values in the table entries to mask or unmask overlay data in associated pixel values. The system can display many tracked objects simultaneously, without high CPU utilization or a program to draw, erase, and redraw tracked objects.
