In certain applications such as radiology and imagery analysis, it is important to minimize errors. In this paper we evaluate a structured inspection method that uses eye tracking information as a feedback mechanism to the image inspector. Our two-phase method starts with a free viewing phase during which gaze data is collected. During the next phase, we either segment the image, mask previously seen areas of the image, or combine the two techniques, and repeat the search. We compare the different methods proposed for the second search phase by evaluating the inspection method using true positive and false negative rates, and subjective workload. Results show that gaze-blocked configurations reduced the subjective workload, and that gaze-blocking without segmentation showed the largest increase in true positive identifications and the largest decrease in false negative identifications of previously unseen objects.

It is increasingly common to find Multiple Display Environments (MDEs) in a variety of settings, including the workplace, the classroom, and perhaps soon, the home. While some technical challenges exist even in single-user MDEs, collaborative use of MDEs offers a rich set of opportunities for research and development. In this workshop, we will bring together experts in designing, developing, building and evaluating MDEs to improve our collective understanding of design guidelines, relevant real-world activities, evaluation methods and metrics, and opportunities for remote as well as collocated collaboration. We intend to create not only a broader understanding of this growing field, but also to foster a community of researchers interested in bringing these environments from the laboratory to the real world. In this workshop, we intended to explore the following research themes:
  • Elicitation and process of distilling design guidelines for MDE systems and interfaces.
  • Investigation and classification of activities suited for MDEs.
  • Exploration and assessment of how existing groupware theories apply to collaboration in MDEs.
  • Evaluation techniques and metrics for assessing effectiveness of prototype MDE systems and interfaces.
  • Exploration of MDE use beyond strictly collocated collaboration.
