The definitive version was published in, ACM Transactions on the Web, Vol. 7, No. 4, Article 20, Publication date: October 2013.http://doi.acm.org/ 10.1145/2529995.2529996[EN] Processing data on any sort of user interaction is well known to be cumbersome and mostly time consuming. In order to assist researchers in easily inspecting fine-grained browsing data, current tools usually display user interactions as mouse cursor tracks, a video-like visualization scheme. However, to date, traditional online video inspection has not explored the full capabilities of hypermedia and interactive techniques. In response to this need, we have developed SMT 2ǫ, a Web-based tracking system for analyzing browsing behavior using feature-rich hypervideo visualizations. We compare our system to related work in academia and the industry, showing that ours features unprecedented visualization capabilities. We also show that SMT 2ǫ efficiently captures browsing data and is perceived by users to be both helpful and usable. A series of prediction experiments illustrate that raw cursor data are accessible and can be easily handled, providing evidence that the data can be used to construct and verify research hypotheses. Considering its limitations, it is our hope that SMT 2ǫ will assist researchers, usability practitioners, and other professionals interested in understanding how users browse the Web.This work was partially supported by the MIPRCV Consolider Ingenio 2010 program (CSD2007-00018) and the TIN2009-14103-C03-03 project.

    Designing for distributed scientific collaboration: a case study in an animal health laboratory

    We have been exploring the design of an advanced collaboration platform to support scientists in a national animal health laboratory to work collaboratively across a physical containment barrier. This paper describes the design considerations based on the findings from a field study of the collaboration processes in this particular environment. We emphasize the need of providing flexible support for various information sharing practices. The major component of the platform â a collaboration environment which integrates life-size video conferencing and a large shared digital workspace - has been under routine use. Our preliminary results from a user study of the distributed group meetings supported by the platform have shown the value of high quality audio-video communication in combination with the feature of allowing access and simultaneously sharing multiple data resources

    Supporting collaborations across a biocontainment barrier

    We present the design process of a collaboration platform which allows research and diagnostics scientists in an animal health laboratory to work collaboratively across a biocontainment barrier. This Biosecurity Collaboration Platform (BCP) integrates high quality audio-video communications with a large shared interactive workspace. It enables real-time sharing of a broad range of data from various data repositories and computer applications, including microscope imaging. We describe the one-year design and development activities which included field study, scenario-based use case analysis, iterative design and evaluations. We highlight factors relating to the unique setting and the associated difficulties in information sharing and communication. We discuss the importance of an appropriate design approach and our solution of an integrated interaction and communication workspace with appropriate configurations to support the scientific collaborations.

    Distributed scientific group collaboration across biocontainment barriers

    This paper reports the findings from a field study of distributed scientific collaboration within a national animal health laboratory. Collaboration in this setting is challenged by the need for biosecurity - there are physical containment barriers between scientists and work groups and movement of people and other physical objects across the barriers requires extensive security procedures. The aim of the field study was to understand how the scientists communicate across the barriers, particularly how they share information and collaborate on its analysis. The findings reveal that the collaboration issues relate not just to the challenges caused by the containment barriers but also to the need for collaboration support between the scientists and their work groups irrespective of the barriers. The paper explains how these findings informed the design of the collaboration platform being installed and how more generic requirements of supporting collaboration over distance were configured and extended to meet the specific requirements of a very particular local setting. © 2012 ACM
