Teleportation — changing the point of view in 3D space by specifying a position — is one of the most common locomotion solutions in VR. However, it currently lacks a mechanism to adjust the height in 3D space, and it is difficult for users to predict the exact final view after the teleportation. Users are relocated to a place without knowing what the final view will look like. As a result, they often need to perform remedial interactions to achieve their ideal position, which can be time-consuming and effort-intensive.
In this paper, we present Fly the Moon to Me (Locomoontion), a novel technique that enables users to bring their destination to themselves through object manipulation. Users first create a copy of the object they want to approach as a preview by selecting it, then bring it to an ideal position and direction using existing object manipulation techniques, and then snap the original object to the preview together with the rest of the world. A controlled experiment with 18 participants via a teleportation task reveals that Locomoontion is more effective than the traditional Point\&Teleport technique with grabbing the world as a remedy to adjust the final positioning.
