Tabletop setups are becoming increasingly popular. Although many researchers are developing different horizontal display setups, there are neither widely accepted standard input devices, nor preferred interaction techniques (such as touch-sensitive displays using fingers and styli).rnThe interaction with digital content, which is too far away, is a primary cause of problems with most of the current interaction metaphors. In most cases, participants have to go physically to the content before they can pick it up by touching the table surface. The authors of this paper propose the TractorBeam, a six degrees of freedom magnetic tracking device, which combines both pointing and touching the interface. The hybrid point-touch interaction technique allows users to point at distant targets and choose between point and touch for closer targets.
