III. It's the little things that matter.
As one of the building blocks of my PhD thesis, I have developed a novel instrument for measuring the usability of web interfaces, which is simply called Inuit—the Interface Usability Instrument1. This was necessary because a usability instrument that is suited for the automatic methods for Search Interaction Optimization I have developed in my PhD… Continue reading INUIT: The Interface Usability Instrument
Earlier this year, I submitted a research paper about a concept called usability-based split testing1 to a web engineering conference (Speicher et al., 2014). My evaluation involved a questionnaire that asked for ratings of different usability aspects—such as informativeness, readability etc.—of web interfaces. So obviously, I use the word “usability” in that paper a lot;… Continue reading What is ›Usability‹?
II. Never hide primary information behind an additional click the user has to perform! Keep the number of necessary clicks as low as possible. For example, in search engines, do not (never ever!) require a user to click twice before they reach their desired result.
Es gibt viel zu viele schlechte Webseiten! Schon mal versucht, auf http://www.finanzen.sachsen.de die Tagessätze für Auslandsreisekosten zu finden? Falls nicht, einfach mal ausprobieren und viel Spaß dabei! Oder schon mal auf der Seite der Uni Würzburg versucht, herauszufinden, wie genau eine Bewerbung für den Bachelor in Wirtschaftswissenschaften abläuft? Nein? Ist auch eigentlich besser so, weil… Continue reading [offene Masterarbeit] Was that Page Pleasant to Use? Usability-Metriken in einer echten Suchmaschine

http://www.youtube.com/watch?v=vj4cNi7O4ws The demo video about usability-based A/B testing I created for the 2014 International Conference on Web Engineering is now featured in the media center of the VSR research group at Chemnitz University of Technology. The chair of VSR is Prof. Dr.-Ing. Martin Gaedke, who is the primary advisor of my PhD thesis. The video… Continue reading First Screencast Published in VSR Media Center
I. If a functionality of an app is hidden in such a way that I can't find it, that functionality is nonexistent.
The continuous evaluation of an e-commerce company's web applications is crucial for ensuring customer satisfaction and loyalty. Such evaluations are usually performed as split tests, i.e., the comparison of two slightly different versions of the same webpage with respect to a target metric. Usually, metrics that stakeholders are interested in include completed checkout processes, submitted… Continue reading Usability-based Split Testing or How to infer web interface usability from user interactions
End of February, I submitted four contributions to the 14th International Conference on Web Engineering: two full papers, one demo and one poster. Of these four submissions, all were accepted and will be presented at the conference, which is to be held in Toulouse (see map below) from July 1 to July 4. In the… Continue reading 4 Submissions accepted at International Conference on Web Engineering (ICWE)
