Scott Snibbe (born 1969 in New York City) is an interactive media artist, researcher, and entrepreneur. He is one of the first artists to work with projector-based interactivity, where a computer-controlled projection onto a wall or floor changes in response to people moving across its surface, with his well-known full-body interactive work Boundary Functions (1998).
Boundary Functions is a set of lines projected from overhead onto the floor, dividing people in the gallery from one another. When there is one person on its floor, there is no response. When two are present, a single line cuts between them bisecting the floor, and dynamically changing as they move. With more than two people, the floor divides into cellular regions, each with the quality that all space within it is closer to the person inside than any one else.

The installation doesn’t function at all with one person, as it requires a physical relationship to someone else. In this way Boundary Functions is a reversal of the lonely self-reflection of virtual reality, or the frustration of virtual communities: here is a virtual space that can only exist with more than one person, and in physical space.
