test pattern
2008 >>

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, the project aims to examine the relationship between critical points of device performance and the threshold of human perception.

This latest audiovisual work from Ryoji Ikeda, presents intense flickering black and white imagery, which floats and convulses in darkness to a stark and powerful, highly synchronised soundtrack.
Through a real–time computer programme, test pattern converts Ikeda's audio signal patterns into tightly synchronised barcode patterns on screen. The velocity of the moving images is ultra–fast, some hundreds of frames per second, so that the work provides a performance test for the audio and visual devices, as well as a response test for the audience's perceptions.
test pattern is the third audiovisual concert in Ikeda's datamatics series, an art project that explores the potential to perceive the invisible multi–substance of data that permeates our world.
Taking various forms – installations, live performance and recordings – test pattern acts as a system that converts any type of data (text, sounds, photos and movies) into barcode patterns and binary patterns of 0s and 1s. The project aims to examine the relationship between critical points of device performance and the threshold of human perception, pushing both to their absolute limits.

test pattern [n˚2] presents flickering black and white imagery that floats and convulses in darkness on two screens, one on the floor and another floor to ceiling, in time with a stark and powerful, highly synchronised soundtrack. Through a real–time computer programme, Ikeda's audio signal patterns are converted into tightly synchronised barcode patterns on the screens. Viewers are literally immersed in the work, and the velocity of the moving images is ultra–fast, some hundreds of frames per second, providing a totally immersive and powerful experience. The work provides a performance test for the audio and visual devices, as well as a response test for the audience's perceptions.

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, the project aims to examine the relationship between critical points of device performance and the threshold of human perception. In this first edition of the project, an audiovisual installation, test pattern involves a sequence of tests for machines and humans, comprising visual patterns converted and generated from sound waveforms in real–time. The installation comprises 8 computer monitors and 16 loudspeakers aligned on the floor in a dark space. The 8 rectangular surfaces of the screens flicker intensely with black and white images, floating and convulsing in the darkness. 16–channel sound signals are mapped as a grid matrix, passing and slicing the space sharply. Via a real–time computer program, the signal patterns are converted into 8 barcode patterns, which are tightly synchronized. The velocity of the moving images is ultra–fast, some hundreds of frames per second at certain points, providing a performance test for the devices and a response test for visitors' perceptions.
