Diamondtouch: A Multi-User Touch Technology
A technique for creating touch sensitive surfaces is proposed which allows multiple, simultaneous
users to interact in an intuitive fashion. Touch location information is determined independently
for each user, allowing each touch on the common surface to be associated with a
particular user. The surface gnerates location dependent electric fields, which are capacitively
coupled through the users to receivers installed in the work environment. We describe the design
of these sytems and their applications. Finally, we conclude with a description of the results we
have obtained with a first generation prototype.
