TurboTurtle is a dynamic multi-user microworld for the exploration of Newtonian physics. With TurboTurtle, students can alter the attributes of the simulation environment, such as gravity, friction, and presence or absence of walls. Students explore the microworld by manipulating a variety of parameters, and learn concepts by studying the behaviours and interactions that occur.TurboTurtle has evolved into a "group-aware" system where several students, each on their own computer, can simultaneous control the microworld and gesture around the shared display. TurboTurtle's design rationale includes concepts such as equal opportunity controls, simulation timing, concrete versus abstract controls, recoverability, and how strictly views should be shared between students. Teachers can also add structure to the group's activities by setting the simulation environment to an interesting state, which includes a set of problems and questions. Observations of pairs of young children using TurboTurtle highlight extremes in collaboration styles, from conflict to smooth interaction. Finally, the technical work in making TurboTurtle group-aware is slight, primarily because it was built with a groupware toolkit called GroupKit.

Almost as long as there have been user interfaces, there have been special software systems and tools to help design and implement the user interface software. Many of these tools have demonstrated significant productivity gains for programmers, and have become important commercial products. Others have proven less successful at supporting the kinds of user interfaces people want to build. This article discusses the different kinds of user interface software tools, and investigates why some approaches have worked and others have not. Many examples of commercial and research systems are included. Finally, current research directions and open issues in the field are discussed.

We have written several multi-user graphical editors in the RENDEZVOUS* system. In our approach to building these editors, the applications are first written as single-user editors. When multiple users wish to share a drawing surface, the drawing surfaces of their individual editors are attached using the Abstraction-Link-View (ALV) architecture. RLinksS communicate the editing operations and and are designed to be invisible to the applications they are attached to, allowing the interface for each user to be highly customized. Links can also attach editors to the interface of a running application, allowing the interface to be edited as the application is being used. Keywords: Collaborative drawing, CSCW, groupware, editors, user interface tools IntroductionWe have written several multi-user drawing programs, and we describe here an architecture for building such applications. Many multi-user drawing programs have been reported in the literature and are reviewed in [3,11]. The design of these drawing programs differ in significant ways, especially with regard to multi-user characteristics. Our goal has been to design an infrastructure which makes it easy for us to build multi-user drawing applications and easily make modifications to explore the implications of various design alternatives.
