Unlike most existing work that focuses on facilitating content placement and transfer, this approach aims at minimizing the effort required to initiate, sustain, and withdraw from interaction with a large public display, and to communicate these capabilities to passersby. We identify barriers hindering this process, and offer advice on overcoming them based on existing work and our own experiences with these displays. We illustrate how this design concept can be applied, and motivate applications in other domains.unknown10.1145/2669485.2669549
