Summary: Masters degree in HCI offered through the School of Informatics at IU.

Summary: Video recording and analysis is an important tool for user experience researchers. This project aimed to learn more about how an interactive video annotation method might affect video analysis. Ink annotations on video were used as the annotation method, and an early prototype was demonstrated to professional user experience researchers. Feedback on the interactive video analysis method was positive. A new tool was designed and is being implemented that emphasized the insights gained from analysis of the initial research, including: collaborative timeline visualization, refined interaction with ink annotation tools, a refined general annotation toolset, and a toolset for reporting findings. Further lessons from implementation are noted, including: video manipulation, space limitations for tool navigation, and reporting tool development.

Summary: We present a study designed to measure the perceptions of the visual design for political websites. We use as our sample population approximately 400 different websites for United States Congressional office-holders. In the analysis and presentation of our results we use the United States map divided into congressional districts, and then encode the study participants' perceptions of the visual design of the websites according to a color scale that maps to the perceived favorability of the site. Our motivation for the visualization is, of course, the well known red-blue map that depicts election results according to support for a particular political party. Further, we intend to look at the competitiveness of the districts where congressional elected officials reside, the noticeable features on their websites (for example, if a blog or visible contact information exists), as well as the results in relation to demographic information about the individual (political party, gender, age, etc). Beyond developing an understanding of the political landscape, our study aims to suggest a set of heuristics that tend to lead to more favorably perceived website designs.

Summary: We present Collaborative Annotations on Visualizations (CAV), a system for annotating visual data in remote and collocated environments. Our system consists of a network framework, and a client application built for tablet PC's. CAV is designed to support the collection and sharing of annotations, through the use of mobile devices connected to visualization servers. We have developed a working system prototype based on tablet PC's that supports digital ink, voice and text annotation, and illustrates our approach in a variety of application domains, including biology, chemistry, and telemedicine. We have created an XML based open standard that supports access to a variety of client devices by publishing visualizations (data and annotations) as streams of images. CAV's primary goal is to enhance scientific discovery by supporting collaboration in the context of data visualizations.

Summary: We present an architecture that enables information visualization activities within a database environment. Our approach presents an abstraction of this transformation process, which we call mapping. The implementation of the mapping process is controlled by the end-user through a Map, which can be used to add order and scale to data.
