Heat maps are an important usability tool for visualizing eye gaze data, mouse movement or click interaction on Web pages. As for mobile applications however, use cases for heat maps are still limited. For example, eye tracking is difficult to realize due to limitations imposed by mobility or hardware requirements. Besides, heat maps for understanding multi-touch interaction are not used as a usability-tool for mobile applications. In this paper we present a concept to generate heat maps for finger-based multi-touch interaction. Our goal is to provide a usability tool for mobile applications that can be used in studies with a huge number of test participants in real-world environments. As a benefit, developers and designers will be able to comprehend user interaction within mobile applications which aids in identifying commonly used
touch gestures, focus areas and points of interest without the need for additional and bulky hardware.
