TL;DR: A comparison study of a mouse, hand tracking, and a combination of a VR stylus and controller for accurate medical marking tasks in virtual reality to find out both objective and subjective preferences from participants.

Abstract: For medical surgery planning, virtual reality (VR) provides a new kind of user experience, where 3D images of the operation area can be utilized. Using VR, it is possible to view the 3D models in a more realistic 3D environment, which would reduce the perception problems and increase spatial understanding. In this experiment, we compared a mouse, hand tracking, and a combination of a VR stylus and a VR controller as interaction methods in VR. The purpose was to study the viability of the methods for tasks used in medical surgery planning in VR. The tasks required interaction with 3D objects and high marking accuracy. The controller combination was statistically significantly the most liked interaction method compared to the other methods. In subjective results, it was the most appropriate, while in objective results, the mouse interaction method was the most accurate.
