Data visualization and electronic health records
- UVis - a tool for local development of interactive graphical user screensVisualization of health records (pdf, 2015)
Visualization with formulas (pdf, 2013)
UVis allows IT-interested users to develop complex screens for local use. "Programming" the screens is done by formulas much like spreadsheet formulas. Real programming is not needed. We have developed the tool and used it to develop an electronic health record system with advanced data visualization.See summary
- Anonymizing a large health record database
Short paper (pdf, 5 pages, 2011)
Long paper (pdf, 13 pages, 2016)
As part of the uVis project, we anonymized a large relational database of electronic health records. This was much harder than anticipated. Structured data in the tables were relatively easy, but identifying data could also hide in free-text notes. We also had to ensure consistency so that data still gave a correct picture of the patient's medical history.

- Why the electronic land registry failed
In 2009 Denmark got a compulsory IT system for Land Registration of ownership. It soon created a national disaster because selling houses and getting mortgages might take months. The press claimed it was yet another IT failure, but actually the IT system worked as intended. What was the real cause? The visible problem was overloaded staff in the Registry Office, but behind this were optimistic estimates of human performance, lack of usability, insufficient user interface requirements, unrealistic SOA requirements, immature risk analysis, and other factors. This paper tells the story in detail. Download (pdf)
- Use case experiment - hotline system (updated 11-01-2012)
In 2009 we conducted an experiment where several professionals and researchers specified requirements for a hotline support system. We got eight replies based on traditional use cases and seven based on task descriptions. It turned out that use cases couldn't cover the customer's needs in areas where improvement was important but difficult. Tasks didn't have this problems and were better in other ways too. See more
