ChalkboARd: Exploring Augmented Reality for Public Displays

Augmented Reality (AR) devices and applications are gaining in popularity, and - with recent trends such as Pokemon Go - are venturing into public spaces where they become more and more pervasive. In consequence, public AR displays might soon be part of our cityscapes and may impact on our everyday view of the world. In this work, we present ChalkboARd, a prototype of an AR-enabled public display that seamlessly integrates into its environment. We investigate the influence of our system on the attention of bystanders in a field study (N=20). The field deployment of ChalkboARd provides evidence that AR for public displays needs to be interactive and adaptive to their surroundings, while at the same time taking privacy issues into account. Nevertheless, ChalkboARd was received positively by the participants, which points out the (hidden) potential of public AR displays.
