GRiD
Project from Moment Factory recreates classic arcade game Pong, controlled by opposing pairs who themselves are the bat, using Lidar to track the players:
Inspired by the incredibly simple game mechanics of table tennis, the arcade classic Pong seemed like an obvious model for a first experiment. Imagined by Nolan Bushnell, developed by Allan Alcorn and brought to market in 1972 by Atari, Pong is one of the first and most iconic arcade games. But despite being revived and adapted countless times, (including Loren Carpenter’s famous 1991 crowd experiment) it had yet to be transformed into a human-scale game integrated with public space. The challenge was therefore to translate the mechanics of the classic 1970’s game into an innovative form by updating the gameplay technology.
GRiD is the culmination of a year or so experimentation using a LIDAR sensor. We saw this technology being used to track moving objects on self driving cars, and we figured we could use it to follow people in public spaces as well—so we ordered one. After writing some custom software to detect point cloud clusters (moving humans), we tested it in our black box and were impressed by its accuracy. With one LIDAR in the corner of the room, we could reliably track the position of a dozen or so people. So we set about turning our 40 x 60 ft. m black box into a giant game interface using Unity as a visual and gameplay frontend. GRiD evolved by iteration. Each time a group of Moment Factory employees came to play in the Blackbox, we collected their reactions and used them to inform the next iteration of the game. This allowed us to fine-tune the speed of the gameplay, and inspired us to spice it up by adding some unexpected effects!
