Self-Moving Robots and Pulverized Urban Displays: Newcomers in the Pervasive Display Taxonomy
In Proceedings of the Eighth ACM International Symposium on Pervasive Displays (PerDis), Palermo, Italy, June 12-14, 2019. ACM, New York, NY, USA. Best Conference-Paper Award.

In this paper, we investigate current approaches to the de- sign of pervasive urban displays through two dimensions: increasing levels of physical integration of content into the surrounding environment (attached, blended, physicalized), and increasing levels of mobility of the display technology (fixed, portable, self-moving). We provide a classification of pervasive displays along these two dimensions and introduce a new class of pervasive display, which we call pulverized urban displays (PUDs). These displays represent content in a physical form, entangled with the built and natural envi- ronment, and are capable of autonomously changing their position. Drawing on urban robotic devices and their capa- bility to sense and manipulate the environment, the paper lays out five characteristics of future forms of PUDs.
