Multiuser Interface Architecture Using Structured Distributed Shared Memories

We are building a window system of the next generation which provides multiuser interface functions, called the BTRON2 window system. It facilitates the construction of multiuser in- terfaces by using' structured distributed shared memories preserving' interaction objects. The main benefit of this architecture is that it can clearly divide multiuser interface modules and application core modules. The focus of this paper is to show that this architecture can pro- vide collaboration-transparent applications with high-level multiuser interface functions such as collision-resolving, flexible coupling', telepointers, and some classes of user interface indepen- dence. This paper also shows their implementation mechanism, and, shortly, the result of its performance evaluation
