“Pure φ (pure φ)” is a video painting as an interface, projected onto a large screen serving as a canvas. If ordinary graphical user interfaces (GUI) realize interfaces as diagrams using symbols and icons, “Pure φ” expresses an interface as a picture, using the screen as a planar field for its canvas. In front of the screen, 4 active digital cameras are installed as metaphors for eyes; optical flow obtained from the input of these 4 cameras sets a feedback loop of random dots in motion. Switching among multiple cameras corresponds to the multiple viewpoints of analytical cubism, projected onto a large screen like an all-over color-field painting. The interface of flowing random dots can be called an abstract interface without concrete metaphors or functions. By scaling the screen to envelop the body and providing, at the viewer's position, a stage with gently graduated levels as a metaphor for the earth, it constructs an ecological-optics interface through the movement of texture as an ambient optic array. In an interface, the balance between transparency (window) and reflectivity (mirror) is particularly important. The noise flowing across the screen through optic flow corresponds to a mirror of movement, while Pure φ, presumably perceived apparently from it—that is, the sense of motion in which “you cannot see what is moving, but can see only movement”—corresponds to what is visible through the window of the screen. In principle, just as countless objects can be reconstructed from 1 retinal image, space arising from the “visuomotor system” in body-centered coordinates is constantly generated and dissolved dynamically. Bodily movement (action) on a stepped stage changes the visual data entering the retina, and that change generates further new actions. The eye itself is the interface for obtaining environmental information, and interaction directly connecting action and vision arises from the dynamism of the direct visuomotor system, rather than an indirect perceptual system seeking constancy.
