Awareness information and user behavior : A field experiment of an online collective system
2005
Ingår i: WSEAS Transactions on Information Science and Applications. - 1790-0832 .- 2224-3402. ; 2:12
Tidskriftsartikel (refereegranskat) abstract
This paper sets out to investigate the effects synchronous non-verbal awareness information has on users of a collaborative system. The experiment was setup in on online picture exhibition where users were given a minimalistic indication of any co-present users present. Logs from the website were analyzed and revealed that users who were in the online gallery and were exposed to the notion that there were other visitors there at the same time spent a statistically significant longer time in the gallery as opposed to visitors who were given the information that they were all alone in the gallery. We also noted that although time in the gallery differed between the two groups, we cannot say anything conclusive as to whether use-patterns differed or not.

Design Patterns for Visualization of User Activities in a Synchronous Shared Workspace
2015
Ingår i: International Journal of Advanced Corporate Learning. - 1867-5565. ; 8:3
Tidskriftsartikel (refereegranskat) abstract
Scholars in fields such as Computer-Supported Collaborative Learning (CSCL) have extensively covered the general theme of distributed collaboration in the past few decades. Recent advances in web technologies have pushed forward the boundaries of what is possible to create on the web, aiding the development of various types of collaborative software. Standing on the shoulders of previous research, and in the light of the new web technologies, we here outline the development of what we label a "synchronous shared workspace". The purpose of the system is to serve as a web-based collaboration tool for small groups of geographically and/or temporally dispersed persons within a learning context. Designing this type of system presents interesting challenges on how to graphically visualize the presence of others and their activities, i.e. awareness information. Further, the system provides other types of functionalities such as visualizing previous activities and real-time manipulation of media objects that provides challenges for designers. Utilizing a "design pattern" approach, this paper explores visualization patterns for collaboration in shared workspaces in order to support mutual awareness and coordination activities. Five design patterns were implemented in the system and evaluated by a small group of online learners. The results support the notion that visualization of awareness information is a complex issue and that the work to provide effortless coordination of collaboration is a research interest that needs more attention.

Designing for technology-mediated collaboration
2018
Doktorsavhandling (övrigt vetenskapligt/konstnärligt) abstract
This thesis concerns the design of a synchronous shared workspace supporting technology-mediated collaboration. In order to collaborate, participants need to be able to coordinate the activity. And to coordinate an activity, they need be aware of others involved in the collaboration. However, what do we need to be aware of concerning the others? And how do we visualize that? Further, how well does contemporary technology support what we need to visualize? And finally, how do we evaluate this type of system, and how do we communicate the results? Two systems were developed having different support for coordination of activities. The first system was used to gain insight into the impact of minimalist awareness information on a web page, while the second system, a web-based collaboration software was developed based on design guidelines emerging from the first system. Two observation studies and focus group sessions, as well as a literature study, supplemented the set of design guidelines into a first set of design requirements for the collaborative system. Inspired by a design science research approach, the system was developed in a cyclical fashion, alternating between development steps and various forms of evaluation. The thesis contributes by supplying a set of design patterns made to support coordination in a shared workspace based on a theoretical construct I call “self-awareness”, where users are not only seeing the activity of others, but also their own activity as seen by the others.

Presenting the Kludd : A Shared Workspace for Collaboration
2015
Ingår i: GROUP '14 Proceedings of the 18th International Conference on Supporting Group Work. - New York : Association for Computing Machinery (ACM). - 9781450330435 ; , s. 295-298
Konferensbidrag (refereegranskat) abstract
In this poster, we would like to present the current state of the Kludd system. Kludd is a web-based collaboration tool, enabling users to collaborate around various media objects like images, videos, texts and audio in a shared workspace. The design metaphor is an online whiteboard, where multiple actors can add, manipulate and remove objects, all while everyone sees the same view. The system is made with standard components like HTML5, CSS3 and a number of open-source javascript libraries enabling real-time collaboration in a browser. Utilizing a Design Science Research methodology, the initial design was based on 9 design requirements. In this poster, a further four requirements are presented as a result of the analysis of the first phase, and an initial design of the second phase of the project is presented

Supporting nomadic work- and study practices in groupware design
2017
Ingår i: Proceedings on E-Learn. - Vancouver, British Columbia, Canada : Association for the Advancement of Computing in Education. - 9781939797315 ; , s. 822-826
Konferensbidrag (refereegranskat) abstract
This brief paper concerns the design of real-time collaborative systems adhering to a nomadic work- and study practice. Nomadic practices can be characterized as having a heterogeneous workplace, working or studying from different locations during a day. This practice has been enabled by advances in technology and formed by human behavior. This means that we now must consider this type of work when designing collaboration software. This brief paper outlines some major issues concerning technology-mediated collaboration arising from nomadic work practices; different network conditions, data cost and device heterogeneity, and proposes tentative design ideas addressing these issues.

Supporting participation in online learning communities with awareness information
2012
Ingår i: International Journal of Web Based Communities. - 1477-8394 .- 1741-8216. ; 8:4, s. 537-549
Tidskriftsartikel (refereegranskat) abstract
This article sets out to investigate the relationship between awareness information and participation in an online learning community (OLC). Inspired by the sociocultural notion of learning as social participation, this article will analyse the events that took place in an online photo gallery equipped with a system for visualising co-present users. The article discusses the importance of why social systems should support the creation, recreation and reinforcement of social norms to better facilitate participation. The article concludes by presenting four design implications of educational technologies supporting participation as well as a section referencing the importance of a transactional perspective in order to understand the effects of awareness information.

Utilizing emerging web standards designing a Synchronous Shared Workspace
2015
Ingår i: Proceedings of E-Learn: World Conference on E-Learning in Corporate, Government, Healthcare, and Higher Education 2015. - Chesapeake, VA : Association for the Advancement of Computing in Education. ; , s. 1157-1161
Konferensbidrag (refereegranskat) abstract
This brief paper is part of a larger project aimed at innovating mediated collaboration in higher education. In this paper, we will discuss technology needed to be able to develop a web based synchronous shared workspace. With the emerging HTML5 standard together with the JavaScript platform called "Node.js" utilizing WebSocket communication, it is possible to create able web based real-time systems. Preliminary testing reveals the setup very reliable, supporting collaborative processes even on bad wireless connections.
