Ray-Casting Based Interaction Using an Extended Pull-Out Gesture for Interactive Tabletops

In this paper, we present a method that allows the users to manipulate a remote object on tabletops using an extended pull-out gesture. The user performs the gesture by moving a ray-cast point projected from the dominant hand between two ray-cast points projected from the non-dominant hand. This allows the user to manipulate a remote object on a tabletop in a similar manner to manipulating a close object. We implemented a test system to the feasibility of our method and we showed applications to manipulate a remote object.
