Abstract

A method of tracking an object 20 comprises providing the object with a reflective or retro-reflective element 22, illuminating a space containing the object, imaging the space with a camera 18 having a pixel based image sensor 18b, and tracking movement and or shape of the radiation reflected from the reflective element. An example implementation is a gaming controller, with the illumination and tracking devices comprising an infra-red LED 14 and a digital image sensor provided at a display screen 10 on which a game to be controlled is displayed. The object may be a pointing device or a hand held gaming implement such as a gun that has a light source that is activated when a trigger is operated. The trigger may operate a mechanical shutter arranged to obscure part of the reflective member. The reflective member may have a particular shape so as to define indicia which is distinctive of one object among others. There may be two light sources 14 and two cameras 18.
