Together with the project partners, Fraunhofer IESE designed a usability test whose empirical and statistically robust results serve to clarify usability and user experience issues.

What is the most suitable presentation and combination of different pieces of information? This question arises on the one hand when systems are developed with varying options for presenting the contents; on the other hand, this is also an issue when a migration is due or when an integrated overall solution is to be created from various systems. This is not only a challenge faced by web designers, but also by all large IT service companies, such as Finanz Informatik, the IT service provider of the Sparkassen Financial Group, whose total banking solution OSPlus is already being used Germany-wide by more than 185,000 employees.
In the study, an objective eye-tracking process was used instead of observation. This process tracks and records a user’s eye movements on the monitor. This makes it possible to accurately detect weak spots in the design and in the interaction.
50 test persons took part in the study. 40 participants formed a neutral group. This allows achieving results that are independent of both prior experiences of a general kind as well as experiences with specific systems of Finanz Informatik. The analysis of the empirically elicited data showed a clear result. This enabled us to make concrete recommendations regarding the structuring of information, which also became part of the company-internal style guide.
