Jedi ForceExtension: Telekinesis as a Virtual Reality interaction metaphor

摘要

Virtual Reality (VR) enables us to freely operate in a space that is unconstrained by physical laws and limitations. To take advantage of this aspect, we have developed a technique for pseudo-telekinetic object manipulation in VR using slight downward tilt of the head to simulate Jedi concentration. This telekinetic ability draws inspiration from The Force abilities exhibited in the Star Wars universe, and is particularly well suited to VR because it provides the ability to interact with and manipulate objects at a distance. We implemented force translate, force rotate, force push and force pull behaviours as examples of the general concept of force extension. We conducted exploratory user testing to assess telekinesis as a suitable interaction metaphor. Subject performance and feedback varied between participants but were generally encouraging.
