Wang, Taowei David, Plaisant, Catherine, Quinn, Alexander J., Stanchak, Roman, Murphy, Shawn and Shneiderman, Ben (2008): Aligning temporal data by sentinel events: discovering patterns in electronic health records. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 457-466. Available online

“Electronic Health Records (EHRs) and other temporal databases contain hidden patterns that reveal important cause-and-effect phenomena. Finding these patterns is a challenge when using traditional query languages and tabular displays. We present an interactive visual tool that complements query formulation by providing operations to align, rank and filter the results, and to visualize estimates of the intervals of validity of the data. Display of patient histories aligned on sentinel events (such as a first heart attack) enables users to spot precursor, co-occurring, and aftereffect events. A controlled study demonstrates the benefits of providing alignment (with a 61% speed improvement for complex tasks). A qualitative study and interviews with medical professionals demonstrates that the interface can be learned quickly and seems to address their needs.”

Quinn, Alexander J., Hu, Chang, Arisaka, Takeshi, Rose, Anne and Bederson, Benjamin B. (2008): Readability of scanned books in digital libraries. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 705-714. Available online

“Displaying scanned book pages in a web browser is difficult, due to an array of characteristics of the common user's configuration that compound to yield text that is degraded and illegibly small. For books which contain only text, this can often be solved by using OCR or manual transcription to extract and present the text alone, or by magnifying the page and presenting it in a scrolling panel. Books with rich illustrations, especially children's picture books, present a greater challenge because their enjoyment is dependent on reading the text in the context of the full page with its illustrations. We have created two novel prototypes for solving this problem by magnifying just the text, without magnifying the entire page. We present the results of a user study of these techniques. Users found our prototypes to be more effective than the dominant interface type for reading this kind of material and, in some cases, even preferable to the physical book itself.”

“ Software design is the act of determining the user's experience with a piece of software. It has nothing to do with how the code works inside, or how big or small the code is. The designer's task is to specify completely and unambiguously the user's whole experience. ”

-- David Liddle, From Bringing Design to Software, edited by Terry Winograd, 1996 ”
