As in previous years the UXcamp Europe 2015 took place in Berlin-Adlershof with more than 500 participants. UXcamp Europe is a conference open to everyone with an interest in UserExperience Design. Year on year, we are joined by many different people from many different countries and with a variety of backgrounds resulting in a broad range of different manners. As BarCamp the UXcamp Europe is an ad-hoc unconference born from the desire for people to share and learn in an open environment. It is an intense event with discussions, demos and interaction from attendees. Anyone with something to contribute or with the desire to learn is welcome and invited to join. Session topics typically include workshops, presentations, case studies, pop songs or open discussions related to User Experience, Interaction Design, Information Architecture, Service Design and similar subjects. This collection of abstracts from the year 2015 shows an overview of the topic of 2015's sessions.
