Publication: Crossover: Tabletop Reaching Behaviour

Interactive tables are becoming increasingly common, but we still have little knowledge of fundamental group interactions over tables. We ran a paper-based study that demonstrates groups' no-crossing social norm: people consider it impolite to cross over or under another person's physical arm. To better understand differences in physical and digital worlds, we replicated the paper-based study on an interactive table. We found the no-crossing norm exists when using touch pens (with physical arms), but not with arm embodiments controlled by mice. We also found people violate the social norm with a realistic looking arm embodiment (a picture of their actual arm), but that introducing a social or performance cost can induce people to follow the social norm. Consequences for the design of interactive tables are discussed.
