Object location and actor prompting system are described to enable an actor to easily find his way around the set, and to focus his gaze on the virtual objects appearing in or disappearing from the studio. The prompting system gives the actor the timings for various events taking place in the studio. The special markings are completely invisible to the camera and to the home viewer because they are either projected in a chroma-key color, or are only active during virtual blanks of the camera as the vertical blanking interval or the horizontal blanking interval in an NTSC, PAL, SECAM or other video signal format. <IMAGE> |
