Abstract

Large and public displays mostly provide little interactivity due to technical constraints, making it difficult for people to capture interesting information or to influence the screen's content. Through the combination of largescale visual output and the mobile phone as an input device, bidirectional interaction with large public displays can be enabled. In this paper, we propose and compare three different interaction techniques (Scroll, Tilt and Move) for continuous control of a pointer located on a remote display using a mobile phone. Since each of these techniques seemed to have arguments for and against them, we conducted a comparative evaluation and discovered their specific strengths and weaknesses. We report the implementation of the techniques, their design and results of our user study. The experiment revealed that while Move and Tilt can be faster, they also introduce higher error rates for selection tasks.
