Global Teamwork: A Study of Design Learning in Collaborative Virtual Environments

With the recent developments in communication and information technologies, using Collaborative Virtual Environments (CVEs) in design activity has experienced a remarkable increase. In this paper we present a collaborative learning activity between the University of Sydney (USYD), and the Istanbul Technical University (ITU). This paper shares our teaching experience and discusses the principles of collaborative design learning in virtual environments. Followed by a study on students’ perception on the courses and collaborative learning in both universities, this paper also suggests future refinements on the course structure and the main areas of collaborative design learning.

Collaborative design in virtual environments

How can architects and engineers work together in the digital world? The article "Collaborative Design in Virtual Environments" provides an answer. The authors describe how the use of virtual reality (VR) and augmented reality (AR) is becoming increasingly important in the architecture industry and what opportunities this opens up. In particular, the article focuses on collaboration in virtual spaces and collaborative modeling of 3D objects. The authors also present a software tool that enables collaborative 3D modeling in virtual environments. The aim of the "Industry 4.0 in Teaching" project is to promote collaboration and joint learning and to prepare students for the requirements of the digital working world.

A Structured Approach for Designing Collaboration Experiences for Virtual Worlds

While 3D virtual worlds are more frequently being used as interactive environments for collaboration, there is still no structured approach developed specifically for the combined design of 3D virtual environments and the collaborative activities in them. We argue that formalizing both the structural elements of virtual worlds and aspects of collaborative work or collaborative learning helps to develop fruitful collaborative work and learning experiences. As such, we present the avatar-based collaboration framework (ABC framework). Based on semiotics theory, the framework puts the collaborating groups into the center of the design and emphasizes the use of distinct features of 3D virtual worlds for use in collaborative learning environments and activities. In developing the framework, we have drawn from best practices in instructional design and game design, research in HCI, and findings and observations from our own empirical research that investigates collaboration patterns in virtual worlds. Along with the framework, we present a case study of its first application for a global collaborative learning project. This paper particularly addresses virtual world designers, educators, meeting facilitators, and other practitioners by thoroughly describing the process of creating rich collaboration and collaborative learning experiences for virtual worlds with the ABC framework

Is spatial intelligibility critical to the design of largescale virtual environments?

This paper discusses the concept of 'intelligibility', a concept usually attributed to the design of real-world environments and suggests how it might be applied to the construction of virtual environments. In order to illustrate this concept, a 3d, online, collaborative environment, AlphaWorld, is analyzed in a manner analogous to spatial analysis techniques applied to cities in the real world. The outcome of this form of spatial analysis is that AlphaWorld appears to be highly 'intelligible' at the small-scale, 'local neighborhood' level, and yet is completely 'unintelligible' at a global level. This paper concludes with a discussion of the relevance of this finding to virtual environment design plus future research applications

Using virtual worlds as collaborative environments for innovation and design: lessons learned and observations from case studies in architectural projects

In this paper we discuss observations and lessons learned in conducting architectural design projects in virtual worlds. By integrating a community of users in virtual worlds into a collaborative architectural design process, organisations can tap the community's creativity and intelligence through immersive technology. The paper provides an overview of the latest advances of information and communication technologies in immersive virtual environments and discusses some of the observations and lessons learned which should be taken into account in developing collaboration models for such activities. Here we propose four modes of collaboration, based on the choices for degree of openness and governance structure, which are illustrated by four case studies

Elaboration of a common frame of reference in Collaborative Virtual Environments

International audienceMotivation – To design virtual environments that support collaborative activities. Research approach – An experimental approach in which 44 students were asked to work in pairs to reconstruct five 3D figures. Findings/Design – The results show that including a contextual clue in virtual environments improves collaboration between operators. Research limitations – Further investigative work must be carried out to extract accurate female collaboration profiles. Originality/Value – The results enable three collaboration profiles to be identified. They also allow the extraction of some characteristics of a contextual clue which can be added to a virtual environment to improve collaboration. Take away message – The contents of a collaborative virtual environment influences the way that users collaborate

Collaborative learning in multi-user virtual environments

Multi-user virtual environments (MUVEs) have captured the attention and interest of educators as remote collaborative learning environments due to their immersion, interaction and communication capabilities. However, productive learning interactions cannot be considered a given and careful consideration of the design of learning activities and organizational support must be provided to foster collaboration. In this paper, a model to support collaborative learning in MUVEs is presented. This model enables the scaffolding of learning workflows and organizes collaborative learning activities by regulating interactions. Software architecture is developed to support the model, and to deploy and enact collaborative learning modules. A user-centered design has been followed to identify successful strategies for modeling collaborative learning activities in a case study. The results show how interactions with elements of 3D virtual worlds can enforce collaboration in MUVEs.Publicad

Influence of Haptic Communication on a Shared Manual Task in a Collaborative Virtual Environment

International audienceWith the advent of new haptic feedback devices, researchers are giving serious consideration to the incorporation of haptic communication in collaborative virtual environments. For instance, haptic interactions based tools can be used for medical and related education whereby students can train in minimal invasive surgery using virtual reality before approaching human subjects. To design virtual environments that support haptic communication, a deeper understanding of humans' haptic interactions is required. In this paper, human's haptic collaboration is investigated. A collaborative virtual environment was designed to support performing a shared manual task. To evaluate this system, 60 medical students participated to an experimental study. Participants were asked to perform in dyads a needle insertion task after a training period. Results show that compared to conventional training methods, a visual-haptic training improves user's collaborative performance. In addition, we found that haptic interaction influences the partners' verbal communication when sharing haptic information. This indicates that the haptic communication training changes the nature of the users' mental representations. Finally, we found that haptic interactions increased the sense of copresence in the virtual environment: haptic communication facilitates users' collaboration in a shared manual task within a shared virtual environment. Design implications for including haptic communication in virtual environments are outlined

Virtual workplaces : when metaphors breakdown

Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1998.Includes bibliographical references (leaves 79-81).Our model of work is shaped by the places we choose to work and the tools we choose to work with. As we introduce new technologies and build new environments our model is changing. Today's virtual workplaces are grounded in models of work that have been reformed from our experiences using current technology in physical workspace. However we are discovering opportunities and possibilities for work in collaborative, virtual environments that question physical models. Emerging patterns of distributed collaboration in persistent virtual environments are changing the way we work in time and space, recasting our notion of workplace. Virtual workplaces are interpreted and experienced through metaphors that describe a space of potential for work occurrences. Through the lens of metaphors, this research focuses on breakdowns between collaborative work and the environment in which work occurs. If what we understand and predict is based on what we already know, then by examining the breakdowns between design and use of collaborative environments we can illuminate the space of possibilities for collaborative work.by Thomas W.I.
