TranSection: Hand-Based Interaction for Playing a Game within a Virtual Reality Game.

TranSection is a new VR interface design concept with cross-dimensional virtual reality interface. It is a 2D puzzle platformer game within a 3D virtual environment. By incorporating the head tracking and visualization capabilities of Oculus Rift and hand tracking capabilities of Leap Motion, TranSection enables realistic interaction with virtual objects through one's own hands. Our evaluation with 12 participants showed that players rated the fun level as 4.17 on a 5-point Likert scale, and 83% of the players would like to play TranSection again. The cross-dimensional interface also significantly reduced simulator sickness, which is one of the critical usability barriers to using virtual reality, compared to the highest rated puzzle game on Oculus Rift.
