Physicality and Cooperative Design

CSCW researchers have increasingly come to realize that material work setting and its population of artefacts play a crucial part in coordination of distributed or co-located work. This paper uses the notion of physicality as a basis to understand cooperative work. Using examples from an ongoing fieldwork on cooperative design practices, it provides a conceptual understanding of physicality and shows that material settings and co-worker’s working practices play an important role in understanding physicality of cooperative design

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

Collaborative production planning with BIM – Design, development and evaluation of a Virtual Production Planning system

Construction projects have for a long time been characterized by increased specialization, low productivity, and a fragmented information exchange culture, resulting in inefficient work processes, with time delays and budget overruns. Research within the context of construction planning and scheduling and IT points to improving communication, collaboration, and cooperation to address these problems. However, the focus has been chiefly on production planning processes and scheduling tools and software. Research also points to collaborative user-friendly scheduling systems remaining under-researched; even though collaborative approaches have been introduced, the technological support and implementations are lacking.In this context, this thesis presents a novel collaborative planning and scheduling process and software system, supporting multiple modes of interaction such as individual review, planning, collaborative scheduling and review work in 4D, both co-located and remote. A Design Science Research approach was used to identify requirements that guided the collaborative production planning system\u27s design and development and evaluations. These evaluations show that implementing the collaborative planning and scheduling system enhances understanding of the planning and scheduling of projects and supports both individual and group work. The developed system facilitates information gathering when creating activities and improves collaborative production of the schedule. Furthermore, the new collaborative setting shortens the length of planning workshops while simultaneously increasing the quality output. Thus, the thesis contributes to the body of knowledge of collaborative production planning, collaborative IT systems in construction, how these systems can support communication and collaborative processes in a social context, and how a design science approach could be used in this setting

Developing a collaborative planning tool for construction - A Building Information Model-enhanced planning and scheduling tool for production.

Construction projects are becoming increasingly complex with a higher degree of specialization, resulting in more sub-contractors as well as in more information needed in the project. This results in a bigger project organization with an increased need for information exchange, an area where construction has been criticized by academics. The increasing specialization is related to an increase in more technically advanced buildings. The amount of information created and managed in construction projects has been recognized as hard to manage at the construction site. This is problem since the site-management uses this information in the scheduling and planning of the production. One way to address this is to utilize the sub-contractors in the planning of the production, thus drawing upon their work-experience for their specific tasks. This creates a collaborative planning approach that somewhat addresses parts of the problem, however, the amount of information is still hard to manage, especially since it has to be coordinated between disciplines to get the full picture. Information and communication technologies, (ICT), have attempted to solve this, with potential found in building information modelling (BIM). However, most use of BIM is seen in the design phase of construction projects, with some BIM visualization appearing at the construction site. The lack of adoption at the construction site is partly attributed to lack of time to alter processes to new tools.This thesis addresses this potential for BIM tools aligned to a collaborative planning process. Furthermore, it recognizes that prior literature lacks a focus on both the people and the social context the technology is used in as well as the development of the technology itself. Thus, a sociotechnical systems view is adopted. Design Science is used as the method to observe the current collaborative planning process, develop a BIM-system supporting the collaborative planning approach and document the research process. This is done with a strong focus on the user,using people, processes and technology as dimension to analyze the requirements of the BIM system developed. Thus, the research’s contribution is threefold; the thesis contributes with a documentation of an existing collaborative planning process, a BIM-enabled collaborative planning tool enhancing a current work practice and anexample of how Design Science can be used as a method to support ICT development in construction

How Feature- and Communication Constraints in CSS Affect Creative Collaboration in Virtual Teams - An Activity Theory Perspective

New Creativity Support Systems (CSS) provide additional features, but are also growing more complex and difficult to operate. Via new functionalities, CSS aim to facilitate virtual creative collaboration and enable better outcomes. However, research shows that, especially in the context of creativity, better outcomes are not always the result of more options and features. Our study applies activity theory (AT) as a lens in order to examine how constraints can be applied to creative collaboration in virtual teams. This study advances research on collaboration in information systems (IS) as well as human-centered development of IT-artifacts that facilitate creative collaboration. Our findings provide two practical takeaways for CSS developers and virtual teams: First, constraints in CSS can be designed to substantially benefit idea generation and exploration beyond routine performance; second, constraints can be designed to help teams access the potential of CSS faster and more efficiently

Co-design of augmented reality textbook for children’s collaborative learning experience in primary schools

Augmented Reality (AR) is a recent technology that allows a seamless composition between virtual objects and the real world. This practice-based research uses the affordances of AR to design an AR textbook for collaborative learning experience. It identifies the key concepts of children s AR textbooks for the designing and evaluation of collaborative learning experiences. These concepts were used to develop a conceptual framework for the AR textbook that considers collaborative experience, learning and usability. Informed by these concepts, the research also has identified the design features which are unique to AR affordances which can be integrated in the school textbooks to develop a collaborative AR textbook for primary school children. The research follows a participatory design approach to involve the users of the AR textbook in the design process. The researcher has conducted three co-design studies involving primary school children and adults using cooperative inquiry techniques. The first study uses low-tech prototyping to find the overall direction of designing the AR textbook. After the development of the first AR textbook prototype, two formative evaluations have been conducted using cooperative inquiry critiquing, and layered elaboration techniques. Throughout these studies, a conceptual framework has been developed namely, Experience, Learn and Use (ELU) for the designing and evaluation of children s AR textbooks for collaborative learning experience. This framework is based on the adaption of Janet Read s Play, Learn, Use (PLU) model that defines children s relationships with the interactive technologies. The research proposes the ELU framework as a useful classification framework in the evaluation process, which informs the design features of the AR textbook which are related to the concepts of collaborative experience, learning and usability. The practical component of the thesis proposes a sample of an AR textbook that is integrated in the regular school curriculum. It demonstrates the design features which can be implemented in other textbooks to support collaborative learning experiences for primary school children. The documentation of the co-design process provides a practical framework for co-designing an AR textbook with children, as well as an evidence of using the ELU framework in practice. 4 This research also contributes in bridging the gap between AR and Child-Computer Interaction (CCI) communities, through the use of common CCI methods in the AR development. This research has resulted in key design principles which contribute original knowledge to the literature of the AR for children s education considering the CCI perspective. These important principles are informed by the collaborative experiences, learning and usability aspects that establish a framework for the design and evaluation of collaborative AR textbook for children. The eight identified principles by this research are, Joint Textbooks, Personalised AR Experience, Interactive AR Book, Communication-Based Learning, Rewarding AR feedback, Audio AR Textbook, Intuitive AR Markers, and Mutual AR Display. The research introduces the definition for each of the concepts and a demonstration of the related design features in the outcome of the AR textbook prototype

Characterizing performance via behavior co-occurrences in a 3D collaborative virtual learning environment : an exploratory study of performance and design

The iSocial 3D CVLE is an innovative design for addressing special needs at a distance that require social and active learning. This exploratory retrospective case study explored innovative methods of analyzing co-occurrences of behavior to gain insight into understanding and evaluating student performance and 3D CVLE design. Visualization techniques were employed to model student behavior within similarly structured activities. Linear mixed models revealed that student performance significantly differed across environments. In addition, environmental design attributes were identified through qualitative memos. General behavior patterns were associated with design environment attributes, warranting further study.Includes bibliographical references (pages 258-272)

Do You Know What I Know?:Situational Awareness of Co-located Teams in Multidisplay Environments

Modern collaborative environments often provide an overwhelming amount of visual information on multiple displays. In complex project settings, the amount of visual information on multiple displays, and the multitude of personal and shared interaction devices in these environments can reduce the awareness of team members on ongoing activities, the understanding of shared visualisations, and the awareness of who is in control of shared artifacts. Research reported in this thesis addresses the situational awareness (SA) support of co-located teams working on team projects in multidisplay environments. Situational awareness becomes even more critical when the content of multiple displays changes rapidly, and when these provide large amounts of information. This work aims at getting insights into design and evaluation of shared display visualisations that afford situational awareness and group decision making. This thesis reports the results of three empirical user studies in three different domains: life science experimentation, decision making in brainstorming teams, and agile software development. The first and the second user studies evaluate the impact of the Highlighting-on-Demand and the Chain-of-Thoughts SA on the group decision-making and awareness. The third user study presents the design and evaluation of a shared awareness display for software teams. Providing supportive visualisations on a shared large display, we aimed at reducing the distraction from the primary task, enhancing the group decision-making process and the perceived task performance

Designing to Support Workspace Awareness in Remote Collaboration using 2D Interactive Surfaces

Increasing distributions of the global workforce are leading to collaborative workamong remote coworkers. The emergence of such remote collaborations is essentiallysupported by technology advancements of screen-based devices ranging from tabletor laptop to large displays. However, these devices, especially personal and mobilecomputers, still suffer from certain limitations caused by their form factors, that hinder supporting workspace awareness through non-verbal communication suchas bodily gestures or gaze. This thesis thus aims to design novel interfaces andinteraction techniques to improve remote coworkers’ workspace awareness throughsuch non-verbal cues using 2D interactive surfaces.The thesis starts off by exploring how visual cues support workspace awareness infacilitated brainstorming of hybrid teams of co-located and remote coworkers. Basedon insights from this exploration, the thesis introduces three interfaces for mobiledevices that help users maintain and convey their workspace awareness with their coworkers. The first interface is a virtual environment that allows a remote person to effectively maintain his/her awareness of his/her co-located collaborators’ activities while interacting with the shared workspace. To help a person better express his/her hand gestures in remote collaboration using a mobile device, the second interfacepresents a lightweight add-on for capturing hand images on and above the device’sscreen; and overlaying them on collaborators’ device to improve their workspace awareness. The third interface strategically leverages the entire screen space of aconventional laptop to better convey a remote person’s gaze to his/her co-locatedcollaborators. Building on the top of these three interfaces, the thesis envisions an interface that supports a person using a mobile device to effectively collaborate with remote coworkers working with a large display.Together, these interfaces demonstrate the possibilities to innovate on commodity devices to offer richer non-verbal communication and better support workspace awareness in remote collaboration

Avatar Training - A Humanistic and Creativity Driven Approach

Avatar Training A Humanistic and Creativity Driven Approach This project is about the development of a program prototype for a humanistic and creativity driven approach to avatar training to be delivered in Second Life™ (SL). Specifically, the program aims at developing the skills necessary to make a presentation in, and to safely explore, SL. It was proposed to create a unique learning framework that takes into account the targeted clientele, adult professionals with no or limited experience with SL, the sensibilities of 3D immersive social virtual environment, the avatar training needs, and the possibility to weave in creativity skills practice. To that end, the resulting framework for a humanistic and creativity driven approach to avatar training integrates elements of the following four learning frameworks: 1) Dialogue Education, a framework for adult learning; 2) Torrance Incubation Model, to weave in creativity skills training; 3) Maslow’s Hierarchy of Needs, to inform the hierarchy of avatar training needs; and 4) Scopes’ Cybergogy of Learning Archetypes and Learning Domains to take advantage of the affordance of Second Life for immersive and experiential learning
