Abstract
Touchless user interfaces are a promising way to let passers-by interact with public displays, but they have to cope with complex social constellations of multiple and novice users. In this paper we discuss how public displays offering touchless interaction can subtly direct individual users and thereby actively shape audience constellations by visual stimuli, thus improving parallel usage and the dynamic of interaction. As a starting point we present our findings from a field study on how a display can direct its users and dissolve crowds by using dynamic visual signifiers. At the workshop we would like to discuss how further touchless applications could benefit from visually moderating their audience.
