“…Firstly, we will extend our idea to mobile and cloud computing environments [50]. Secondly, we will enhance our algorithm in real-world applications, such as collaborative digital design [51][52][53][54][55][56][57][58][59][60][61] and knowledge-sharing social network or community [62][63][64][65][66]. Thirdly, we will discuss how to accelerate massive-scale collaborative applications with parallel and optimization methods [67][68][69][70][71][72].…”

Multi-user collaborative editors are useful computer-aided tools to support human-to-human collaboration. For multi-user collaborative editors, selective undo is an essential utility enabling users to undo any editing operations at any time. Collaborative editors usually adopt operational transformation (OT) to address concurrency and consistency issues. However, it is still a great challenge to design an efficient and correct OT algorithm capable of handling both normal do operations and user-initiated undo operations because these two kinds of operations can interfere with each other in various forms. In this paper, we propose a semi-transparent selective undo algorithm that handles both do and undo in a unified framework, which separates the processing part of do operations from the processing part of undo operations. Formal proofs are provided to prove the proposed algorithm under the well-established criteria. Theoretical analysis and experimental evaluation are conducted to show that the proposed algorithm outperforms the prior OT-based selective undo algorithms.

“…Gao et al [9] remodel the 2D graphical operations as linear operations by mapping the two-dimensional drawing area into a linear structure, for the purpose of collaborative image manipulation. For preventing conflicts related to consistency, Wu et al [26] present a generic Common Graphics Collaborative Editing (CGCE) algorithm. To showcase their methods, both Gao et al and Wu et al choose current webbased technologies, however, as a functionality they only focus on sketching or primitive geometric shape editing.…”

Various web-based image-editing tools and web-based collaborative tools exist in isolation. Research focusing to bridge the gap between these two domains is sparse. We respond to the above and develop prototype groupware for real-time collaborative editing of raster and vector images in a web browser. To better understand the requirements, we conduct a preliminary user study and establish communication and synchronization as key elements. The existing groupware for text documents or presentations handles the above through well-established techniques. However, those cannot be extended as it is for raster or vector graphics manipulation. To this end, we develop a document model that is maintained by a server and is delivered and synchronized to multiple clients. Our prototypical implementation is based on a scalable client–server architecture: using WebGL for interactive browser-based rendering and WebSocket connections to maintain synchronization. We evaluate our work qualitatively through a post-deployment user study for three different scenarios. For quantitative evaluation, we perform a thorough performance measure on both client and server side, thereby identifying design recommendations for future concurrent image-editing software(s).

“…It was was introduced as one of HTML5 technology standard for active content delivery over the Internet through full-duplex communication channels [31]. Delivering real-time information and constant changes to a client, such as collaborative working systems [32][33][34] and online games [35,36], requires a persistent socket connection between client and server. In a classic client-server web application, real-time complex communication was difficult to achieve without having users constantly poll requests to retrieve the updated information [37].…”

A concept map is deemed a useful teaching and learning tool. It offers many potential advantages over just representing the students’ knowledge and understanding during learning, and have been widely used to support learning. Kit-Build concept map is one learning framework that incorporate digital concept map for its learning activities. Learning with Kit-Build concept map has been found to have better learning effects towards students' understanding and knowledge retention. Incorporating Kit-Build concept map into collaborative learning have been reported to have better outcome than the traditional collaborative learning. However, collaborative learning with Kit-Build concept map cannot be accomodated with the current Kit-Build system where learning activity is conducted online. This study presents the design and development of online collaborative learning platform of Kit-Build Concept Map. A prototype of the collaboration system to support collaborative learning with Kit-Build concept map is developed and be evaluated to portray its potential usability for further development and practical use. The result suggested that incorporating Socket.IO as a real-time communication middleware is effective to deliver online collaborative learning features into the Kit-Build system. Preliminary evaluation to the system also suggested that the system has the potential for actual use in supporting distant collaborative learning with Kit-Build concept map.
