Executive Summary

Mobile phones can help one stay connected with friends, family, and colleagues. Yet they can also sometimes isolate one from the physical world around one, drawing the attention into a relatively private, personal, digital world of calls, text messages, and email. Further, mobile phones' small screen size and limited viewing angle make it difficult to share displayed information with co-present people. One can hold a phone up for others to see or pass it around yet neither strategy adequately facilitates simultaneous group-based communication or lightweight, opportunistic interaction. Public displays, in contrast, present information to many people simultaneously, and have been shown to catalyze conversation and interaction.
