The work analyzes the fundamental components of video: the camera, the monitor, and the frame, focusing on the role of each within a system of video as analogous to the functions of vision and speech.

His major works include Ai (Love) (1962), Observer, Observed (1975), and Ma: Space/Time in the Garden of Ryoan-ji (1989), which includes texts by Arata Isozaki and music by Takehisa Kosugi.
