Live action fighting games

Participants use NES controllers to play what looks like an old video game. Obscured behind the TV set, trained actors respond to the buttons pressed on the controllers by moving forward, backward and punching left or right. The actors cannot see anything other than lights indicating which action to perform. They are then digitized by a camera and placed within the video game screen. A health bar on the TV tracks the health of each player which responds to switches in each actor’s mask to detect a hit. The hardware interface uses two BasicStamps and the video game software is made with processing. Source: hackaday.com
