As public display networks become open, noveltypes of interaction applications emerge. In particular, we expectapplications that support user-generated content to rapidly gainimportance, since they provide a tangible benefit for the userin the form of digital bulletin boards, discussion platform thatfoster public engagement, and applications that allow for selfexpression.At the same time, such applications infer severalchallenges: first, they need to provide suitable means for thepasserby to contribute content to the application; second, mechanismsneed to be employed that provide sufficient control for thedisplay owner with regard to content moderation; and third, theusers’ expectations with regard to the posting procedure needsto be well understood. In this paper we present UniDisplay, aresearch prototype that enables users to post text and images toa public display. We report on the design and development ofthe application and provide early insights of the deployment ina University setting.    «
