Summary: Mid-air gestures offer a promising way to interact with large public
displays. User representations are important to attract people to such
displays, convey interactivity and provide meaningful gesture feedback. We
evaluated two forms of user representation, an abstract skeleton and a
silhouette, at a large public information display. Results from 56 days, with
190 sessions involving 483 detected people, indicate the silhouette attracted
more passers-by to interact and, of these, more engaged in serious browsing
interactions. By contrast, the skeleton representation had more playful
interactions. Our work contributes to the understanding of the implications of
these choices of user representation.
