The use of augmented reality is becoming more and more commonplace. Whether via smartphone apps, on television or while driving a car, almost everyone has already encountered this technology more or less knowingly. In this paper, we investigate to what extent Augmented Reality (AR) can be used profitably in public transport, especially on semi-transparent display screens. These semi-transparent and interactive public displays are built-in as windows in public transport vehicles. In our research project SmartMMI these mobile public displays are called “SmartWindows”. We implemented an iterative evaluation concept containing of four phases to assess different types of AR content to be displayed on such a SmartWindow as well as the special interest of individual types of users. Based on the results of two conducted online studies, specific user scenarios were created and evaluated in a lab-based user study. Finally, we designed an online survey to determine which AR concepts are most accepted by users. In this video-based survey, we evaluated the running speed of AR object inserts, the colors, the fade in’s and the types of information displayed on a semi-transparent display. In this paper, we introduce all four stages of our iterative evaluation process, and focus further on study methodology, set-up and the results of the video-based online survey.
