Summary: During conversational practices, such as a tablet-mediated sales
conversation between a salesperson and a customer, tablets are often used by
two users who prefer specific bodily formations in order to easily face each
other and the surface of the touchscreen. In a series of studies, we
investigated bodily formations that are preferred during tablet-mediated sales
conversations, and explored the effect of these formations on performance in
acquiring touch targets (e.g., buttons) on a tablet device. We found that
bodily formations cause decreased viewing angles to the shared screen, which
results in a decreased performance in target acquisition. In order to address
this issue, a multi-modal design consideration is presented, which combines
mid-air finger movement and touch into a unified input modality, allowing the
design of proximity sensitive touch targets. We conclude that the proposed
embodied interaction design not only has potential to improve targeting
performance, but also adapts the 'agency' of touch targets for multi-user
settings.
