From 2003 to 2008, I was a staff member and PhD candidate at the department of media informatics (Lehr- und Forschungseinheit Medieninformatik, Prof. Hußmann) at Ludwigs-Maximilians-Universität München. I am still reachable at

[I used to be a student at Munich's other university, Technical University of Munich. Information about various aspects of my student life is still available, including an overview page, Belfast Survival Guide, diploma thesis, VDM-SL project, crypto.]

Research Interests

My research interests include:

• Web Engineering
• Usability (and modelling of usability-related information)
• Modelling of business processes/workflows for web applications
• Automated tool support for modelling/testing
• (Accessibility, device independence of websites)

PhD Thesis: Usability Tool Support for Model-Based Web Development

I have submitted my thesis, and defended on 2008-10-09. This graph shows my progress during the ≈8 months I worked on it.

Each dot is one SVN commit. Scripting all of this prevented useful work on the thesis for an entire afternoon, so of course I had to do it... ;-)

UsaProxy

Together with Monika Wnuk, I developed UsaProxy, an HTTP proxy for user interaction logging with AJAX websites. Visit Moni's UsaProxy homepage for source code and further information! On this server, there is a backup of the UsaProxy code.

Publications in order of importance: WWW 2006, CHI 2007, INTERACT 2007, WWW 2006 workshop

Known bugs and limitations (patches are welcome!):

• No support for HTTPS, not even pass-through. Configure your browser to use no proxy for SSL.
• The logging of absolute mouse coordinates with -log was accidentally disabled in UsaProxy 2.0: Patch
• Bug: UsaProxy 2.0 also seems to lose some JavaScript events occasionally. Maybe try version 1.5 if you experience problems.
• Bug: HTTP headers are stored in a hash table. This has the undesired effect that multiple identical headers will not be forwarded correctly, in particular multiple Set-cookie headers. Causes problems e.g. logging into GMail.

WebpageMap

As part of his project thesis, Philip Lorenzi implemented the WebpageMap (publication at NordiCHI 2008), a browser extension designed to help users navigate on long web pages, using a heatmap and a pop-up table of contents. Watch the WebpageMap video!

You can try out WebpageMap yourself: Install the Firefox web browser together with the Greasemonkey extension. WebpageMap is implemented as a Greasemonkey script which gets executed on all web pages. With Greasemonkey installed, click on this link to install and enable the WebpageMap script: WebpageMap Greasemonkey script

The implementation has only some minor problems at the moment: Performance is worse than it could be because the heatmap is recalculated too often (especially noticeable after keypresses). The heatmap information for pages is never expired. Changes to the web page content will not be noticed, so the heatmap may no longer be accurate after content changes. The script stores the heatmap data permanently in a way that will add a lot of entries to Firefox's "about:config" list. To get rid of these entries, be sure to enable the option "also uninstall associated preferences" in the Greasemonkey dialog when you uninstall WebpageMap.
