A Novel Bare-Handed and Widget-based Manipulation Technique for Distant Objects in Virtual Reality

Recent advancements in bare-hand tracking technology in VR headsets enable intuitive hand interaction for proximate 3D object manipulation. This paper explores two-handed bare-hand interaction for distant 3D objects, by using the non-dominant hand as an interaction surface to enable adept manipulation of a distant 3D object’s position and rotation. A user study demonstrated markedly higher precision in complex manipulation tasks compared to traditional methods while maintaining comparable efficiency and accuracy for simpler tasks. Our method also received a good usability rating, illustrating its user-centric and intuitive nature. We discuss insights on error prevention, constraint integration, and consistent interaction for future VR interaction methods.
