The Annotators' Perspective on Co-authoring with Structured Annotations |
ABSTRACT: Research has shown that grouping related annotations together can help those who review an annotated document by reducing their workload and raising the accuracy of their reviewing. Less is known about the impact on users who create these structured annotations – the annotators. The goals of the research reported in this paper were: (1) to better understand current annotation creation practices, (2) to explore how structuring can be used by annotators, both the structuring process and resulting types of structure, and (3) to evaluate the impact on annotators of having to create structured annotations. We conducted three studies to address each of these goals and learned that structured annotations are perceived to be worth the additional workload and that the bottom-up grouping approach complements the top-down approach in describing relationships amongst annotations in a document. |

Evaluation of a Role-Based Approach for Customizing a Complex Development Environment |
Coarse-grained approaches to customization allow the user to enable or disable groups of features at once, rather than individual features. While this could reduce the complexity of customization and encourage more users to customize their interfaces, the research challenges of designing such approaches have not been fully explored. To address this limitation, we conducted an interview study with 14 professional software developers who use an integrated development environment that provides a role-based, coarse-grained approach to customization. From the results, we identify challenges that are inherent in designing coarse-grained customization models, including issues of functionality partitioning, presentation, and individual differences. |

LiveRAC: A scalable network management visualization system |
We describe a scalable network management visualization system called LiveRAC that uses live streaming data and implements a novel accordion drawing + semantic zoom interaction technique. The field deployed system helps network operations staff manage complex environments. The LiveRAC visualization system shows alarm and metric data such as CPU usage and available memory for a large collection of machines simultaneously using semantic zooming, allowing the user to choose which servers to inspect with detailed charts while still showing a compressed view of the entire information space. |

A Visual Exploratory Data Analysis Tool At Work: Contextual Inquiry of Session Viewer |
We conducted a contextual inquiry to study visual exploratory analysis of web session logs with Session Viewer at the workplace. With seven log-analyst participants working on their own experimental data, we collected 20 hours of tool use, and grouped our findings into two themes: (1) design implications in dealing with real-world noisy data, and (2) factors that affect eventual tool adoption in the workplace. We find that noisy data requires substantial data validation and selection that should be facilitated by the tool. The level of tool flexibility should be based more on target users’ technical skills than on data. The tool should allow fluid data projection to support frequent analysis direction changes. For tool adoption, we believe the strongest determinant is whether the tool fulfills a true need in the analysis process. For large data analysis, integration to current tool set is not as critical as we once assumed. |

Exploring Methods to Improve Pen-based Menu Selection |
A previous study of Tablet PC pen interaction determined that selecting the top edge of the menu item below the target item was a major source of selection errors. We conducted a study to investigate two different approaches to correcting for this error, comparing them to each other and to a control condition. The first approach is to deactivate the top edge such that it functions as an invisible menu separator. The second is to reassign the top edge such that taps in this region are interpreted as selection of the item above, while leaving the visual appearance of the items unchanged. |

Many lecture halls and conference rooms today are equipped with multiple projectors and large high-resolution displays. Existing presentation software, however, only support a single, static slide projected on one full screen. With the goal of designing richer presentation tools that can take advantage of the increased screen resolution and real-estate, we conducted an observational study that examined current practice with visual aids in presentations. We observed both traditional visual aids such as whiteboards and blackboards as well as presentations using computer generated slides. By observing presentations in both classroom and conference settings we were able to devise several design guidelines for building presentation tools that are aimed at enhancing audience learning. Finally, using these guidelines, we have designed an initial prototype system for authoring and presenting a presentation on multiple displays. |
