SmartMMI includes the development of a working prototype of a semi-transparent, interactive display for public transport vehicles. In this user study we were able to test several design prototypes in our mockup tram compartment and gained valuable insight on the usability of several aspects of our prototypes.
Additionally, towards the end of our project, a field test is planned. Two prototypical semi-transparent displays will be implemented in a tram of the local public transport provider. We are currently planning the usability evaluation of our system in the field and in order to do that, we conducted a study to test various evaluation methods in the mockup tram department. We wanted to determine the best suitable evaluation methods for subsequent studies in real public transport environments. Based on the results of this study, we developed our evaluation concept for the upcoming field test.
