ABSTRACT
As everyday companions, smartphones are well-suited tools for controlling interactive applications on large public displays. To allow concurrent interaction by multiple users beyond traditional collaborative scenarios we introduce the idea of virtually augmented public screens for creating personalized views and thus literally enabling "private public screens". We present a fully functional research prototype in form of a Video Wall application and report on first experiences gathered from a comparative user study. The results show that the proposed personalized Augmented Reality approach, which allows each user to have a private view on the public display, is preferred over a purely competitive mode, where the public display is shared between the users. Further, our study shows that social activity indicators informing about the activities of other users are well appreciated.

Design implications for interacting with personalised public displays through mobile augmented reality
PerDis '16: Proceedings of the 5th ACM International Symposium on Pervasive DisplaysDue to their situated nature, digital public displays have the potential to provide information and messages to large groups of people. However, in practice, non-customised content typically is not relevant to every passerby, while personalising ...

Proxemic Interaction Applied to Public Screen in Lab
Proceedings of the First International Conference on Distributed, Ambient, and Pervasive Interactions - Volume 8028Proxemics is the terminology used to describe spatial relationships among humans while communicating with each other. It could be interesting to apply the proxemics theory to the domain of human computer interaction, namely proxemic interaction. ...
