“…Almost all existing bitmap-based collaborative graphics editing systems including CrystalBoard [2], WScrawl [23], WE-MET [24] and GroupSketch [7] do not support the undo function. WScrawl is based on a centralized architecture and does not cause the concurrent problem.…”

Bitmap-based collaborative graphics editing systems are a special class of real-time collaborative editing systems. Undo is an important and difficult problem in these systems. Existing solutions show low efficiency because additional space cost should be added to achieve the function of undo. In this paper, we propose a new solution to resolve the undo problem. The basic idea is to reduce space cost through exploring relations among operations. The algorithm given in the paper can undo any operation at any time, and can greatly reduce the space cost while increasing a few time cost. The issues about undo scope and undo mode are also discussed in the paper.

Our work focuses on providing computational support for informal communication among people who are geographically separated. To better understand the use of artifacts in communication, we looked at the contents of office whiteboards after they had been used in conversations. Our analysis revealed that whiteboards are used to present and discuss various classes of objects with specific semantic properties. We call these objects "conversational props," and we have come to think of a whiteboard as a conversational medium in which props are introduced and manipulated. This study motivated our design of the Conversation Board, an experimental prototype of a multi-user drawing tool which allows remote use of conversational props. We compare the Conversation Board to various other multi-user drawing tools along a number of dimensions.
