In the case of large interactive display walls, simultaneous interaction by multiple users becomes possible and consequently, the system needs to adapt to each user at a more fine-grained level. This paper considers the challenges that follow and examines proposed solutions. We first look at requirements for a system that technically identifies the different users and compare existing systems to these requirements. Second, we discuss how to adapt the interface to multiple, possibly collaborating, users: How do we display personal or private data? How do we adapt to users that move around? In a collaborative environment, there is often a need for personal views of data in addition to a shared view. We consider both lens-based user interfaces and the use of additional personal mobile devices as mechanisms for enabling personalized interfaces.enDisplay WallMulti-UserCollaborationPersonalized InteractionText/Workshop Paper10.18420/muc2017-mci-0314
