The motion picture branching method is superseded by an animation method which enables rapid and repeated switching of multiple tracks of different camera-originated animation of the same character during continuous action in a scene, and enables branching at the termination of an action to multiple actions or scenes. This method is the basis of a double-circuit video system that enables a player to repeatedly touch or hit an animated character during a continuous action as displayed on a projection screen or television monitor and thus change the action repeatedly. Another system embodiment enables the player to swing a racket before the screen or television monitor, hit the mid-air projected image of a perspective ball animated action, return the ball back to the animated character opponent, and play a simulated game during the the player exercises the same skills used to play the game simulated. An ultrasonic transducer of a playing instrument and a microphone combination on the television face or at angles to the playing action produces a readout of the television contact position or the mid-air position of the playing instrument relating to the game. The readout signal is converted into digital form and compared to a similar readout in digital form of the position of the character or object in the frame of the animation displayed by the television and digitally coded in the video tape or disc.
