Today's European data protection principles especially contradict the ideas of ubiquitous computing. Additionally, users have to deal with unconventional interaction concepts that create unknown usage situations. Resulting uncertainties leads to a low amount of trust and acceptance in such systems. We apply the VENUS Development Method to develop a ubiquitous smartphone application, called Meet-U. The application supports users during the organization of meetings. We present our results from the development process. Furthermore, a laboratory experiment with 283 undergraduate students was performed to evaluate different disciplinary and multidisciplinary aspects.enMeet-U: Mobile Social Networkbook section
