We describe the design of and experience with PointRight, a peer-to-peer pointer and keyboard redirection system tha operates in multi-machine, multiuser environments. PointRight employs a geometric moel for redirecting input across screes drive by multiple independent machines and operating systems. It was created for interactive workspaces that include large, shared displays and individual laptops, but is a geneal tool that supports many different configurations and modes of use. Although previous systems have provided for re-routing pointer and keyboard control, in this paer we present a more general and flexible system, along with an analysis of the types of re-binding that must be handled by any pointer redirection system. This paper descibes the system, the ways in which it has been used, and the lessons that have been learned from its use over the last two years. |
