Cinematrix ® audience participation system R. and L. Carpenter (1992)

(x,y) Audience (2 groups): Cursor on Shared Screen: dx dy

(x,y) Audience (2 groups): Cursor on Shared Screen: dx dy

(x,y) Audience (2 groups): Cursor on Shared Screen: dx dy

Formal Model of Cinematrix

Audience Member Response x = [x + f x (x), y + f y (x)] T + where: x = [x, y] T f : Q(x, y) x sgn(g(x, y)){0, +1, -1} g(x, y) = x 2 + y 2 - r 2

Performance Metric Error =  |local error| / total area Performance = 1 - Error

We can measure Performance as we vary Audience Diversity: Drop outs Malicious Players Random Players Time Delayed Players

% drop-outs, 50%100% 0% Performance 0% 63% 100% % malicious players

Campus Policy on Imaging taxonomy: (a) security (b) research involving human subjects (c) other: including journalism, art, public relations, etc. Proposal: Campus Camera Registry: updated campus guidelines, sources for further information, campus camera location and contact information.

Project Witness Peter Gabriel

Sample Questions: Who is responsible for camera policy? What should be covered? Distinctions between private and public access? Consequences of dummy cameras? What are expectations of privacy in public spaces? How to insure adequate notification?

Public: L. publicus: belonging to the group Private: L. privus: single, individual, that which stands apart from the group
