test pattern is a system that converts any type of data (text, sounds, photos and movies) into barcode patterns and binary patterns of 0s and 1s. Through its application, this project aims to examine the relationship between critical points of device performance and the threshold of human perception. From large-scale installations to live performances, the test pattern project has been derived from many different types of application since 2008, including a compact disc version and the more notable series of site-specific installations such as those recently presented at La Villette (Paris) and 180 The Strand (London) in 2017.

This is the first publication related to the project.

Concept by Ryoji Ikeda, Computer graphics and programming by Tomonaga Tokuyama
