Today´s smartphones provide the technical means to serve as nterfaces for public displays in various ways. Even though recent research has identified several approaches for mobile-display interaction, inter-technique comparisons of respective methods are scarce. In this chapter, the authors present an experimental user study on four currently relevant mobile-display interaction techniques (`Touchpad´, `Pointer´, `Mini Video´, and `Smart Lens´). The results indicate that mobile-display interactions based on a traditional touchpad metaphor are time-consuming but highly accurate in standard target acquisition tasks. The direct interaction techniques Mini Video and Smart Lens had comparably good completion times, and especially Mini Video appeared to be best suited for complex visual manipulation tasks like drawing. Smartphone-based pointing turned out to be generally inferior to the other alternatives. Finally, the authors introduce state-of-the-art browser-based remote controls as one promising way towards more serendipitous mobile interactions and outline future research directions.
