We describe a new technique for tracking and identifying multiple laser pointers simultaneously in a large screen collaborative environment. Our method is based on using a video camera to track and decode the laser pointers. We use an asynchronous serial bit stream created by blinking the laser light to encode the identity of each laser. Our goal is to use multiple laser tracking in large scree...

Knowledge of the actions of other users is essential to the design of an effective collaborative authoring system. The reasons for this are rooted in the concept of awareness of individual and group activities. This research presents CAWS, a collaborative authoring system that builds upon several areas of research including studies of co-authoring practices, studies supporting awareness in coll...

This study examines online collaborative writing (CW) teaching techniques via asynchronous computer-mediated communication multimodality, i.e., Google Docs. attempts to investigate what Indonesian learners perceive concerning collaboratively in Docs during learning. collected data from 20 Primary School Teacher Education (PSTE) students enrolling an English 3 (Academic Writing) class at a priva...

Research has shown that classroom learning improves significantly when a student participates in learning activities with small groups of peers. This educational value of student collaboration has led to the development of computersupported collaborative learning (CSCL) tools. These tools enrich learning in a setting that encourages students to communicate with their peers. In typical webbased ...

The benefit of experience, tempered with the wisdom of hindsight and 5 years of text-based, asynchronous, computer-mediated, interdisciplinary team communications, provides the energy, insights and data shared in this article. Through the theoretical lens of group dynamics and the epistemology of interdisciplinary teaming, we analyze the interactions of a virtual interdisciplinary team to provi...

background and purpose: active learning, combined with computer-assisted instruction, can enhance medical students’ performance and learning. this article is an attempt to introduce a new web-based approach to information technology instruction for medical students. methods: eight topics were selected to be instructed in web-based workshops. phpbb forum was used for web-based collaborative lear...

In this paper the authors present an overview of recent work on ongoing projects at the Audiovisual Institute from the Pompeu Fabra University in Barcelona, focused on Internet collaborative virtual environments for music applications. Although presenting different strategies, they all put a special emphasis in performance and composition/production of music by groups of geographically disperse...
