Pointeurs multiples!: étude et implémentation

This paper describes the main cases of multiple pointer interaction and proposes a new notation (named UDP/C) for classifying and comparing these systems. A technical solution that makes use of two complementary tools is presented in the second part of the paper. This imple- mentation can support most cases of multiple pointer in- teraction. It is currently based on the X-Window win- dowing system and the Ubit toolkit.
