Abstract
Some embodiments provide a tracking device for use in obtaining information for controlling an execution of a game program by a processor for enabling an interactive game to be played by a user. The tracking device comprises a body having a section to be oriented towards a screen when a progress of a game provided via execution of the game apparatus is displayed upon the screen; and at least one photonically detectable ('PD') element assembled with the body, a position of the photonically detectable element within an image being recordable by an image capture device when the section is oriented at least partly towards the screen, wherein positions of the PD element at different points in time are quantifiable to quantify movement of the body in space.
