Journal ArticleDOI
Transparent adaptation of single-user applications for multi-user real-time collaboration
TL;DR: An innovative Transparent Adaptation approach and associated supporting techniques that can be used to convert existing and new single-user applications into collaborative ones, without changing the source code of the original application are reported.
Proceedings ArticleDOI
Leveraging single-user applications for multi-user collaboration: the coword approach
TL;DR: This approach has been applied to transparently convert MS Word into a real-time collaborative word processor, called CoWord, which supports multiple users to view and edit any objects in the same Word document at the same time over the Internet.
Proceedings ArticleDOI
Operational transformation for collaborative word processing
TL;DR: An extension of OT is reported for supporting a generic Update operation, in addition to Insert and Delete operations, for collaborative word processing, which is relevant not only to word processors but also to a range of interactive applications that can be modelled as editors.
Journal ArticleDOI
Context-Based Operational Transformation in Distributed Collaborative Editing Systems
David Sun,Chengzheng Sun +1 more
TL;DR: This paper analyzes the limitation of the causality theory, proposes a novel theory of operation context as the new foundation for OT systems, and presents a new OT algorithm-Context-based OT (COT)-which provides uniform and efficient solutions to both consistency maintenance and undo problems.
Proceedings ArticleDOI
MouStress: detecting stress from mouse motion
TL;DR: It is argued that mouse sensing "in the wild" may be feasible, by analyzing frequently-performed operations of particular geometries, and it is shown that the within-subject mouse-derived stress measure is quite strong, even compared to concurrent physiological sensor measurements.
