This paper presents the results of a field study of the COHIBIT museum exhibit. Its purpose is to convey knowledge about car-technology and virtual characters in an entertaining way. Two life-sized virtual characters interact with the visitors and support them in constructing car models with specific tangible car modules. The evaluation should reveal what makes the exhibit successful in terms of an overall user impression and how users rate the employed virtual characters. The focus of the evaluation is to measure the user experience that manifests in aspects like attraction, rejection and entertainment. Based on an analysis of relevant systems and evaluation models, an on-site evaluation for the COHIBIT exhibit has been designed. The results show that the positive user experience of the exhibit is mainly based on the non-task-specific aspects like virtual characters, joy of use and entertainment.
