We developed Arm-a-Dine, a social eating system that uses an on-body third arm to explore augmented eating experiences. Arm-a-Dine is a novel interactive multiplayer experience where a third (robotic) arm attached to the stomach of the person supports his/her eating, in particular, we sense facial expressions of other co-eaters to guide the actions of the third arm, fuelling the interlink between eating and facial expressions. With our work, we aim to explore the potential of embodied systems to support the social eating experience.
