Influencing tabletop interaction speed: directness and device

This thesis presents two studies into factors that influence speed of passing documents on a tabletop display. Document passing consist of rotation and translation tasks. Two interaction techniques that support both rotation and translation, RNT and Corner, were compared in both studies. The RNT technique is an semi-integral technique and combines rotation and translation. The Corner technique is a separate technique and requires a separate rotation and a separate translation movement.
