It has become increasingly common for new dance theater works to combine the movement of live dancers with the movement of computer-generated graphics projected onto the stage. Such works typically either manipulate carefully pre-made motion-capture material or, alternatively, a variety of indirect sensing technologies on the dancers themselves. What happens if the computers can see a high-resolution, real-time motion capture of the dancers in the theatre as the dance unfolds? How should such hybrid, collaborative pieces be made? Two new pieces are being created to help answer these questions. "How long will the subject linger on the edge of the volume?" is a new piece with the Trisha Brown Dance Company, and "22" is being created with Bill T. Jones.
