Comparison of a VR Stylus with a Controller, Hand Tracking, and a Mouse for Object Manipulation and Medical Marking Tasks in Virtual Reality

In medical surgery planning, virtual reality (VR) provides a working environment, where 3D images of the operation area can be utilized. VR allows imaging data to viewed in more realistic reducing perceptual problems and increasing spatial understanding. present experiment, we compared mouse, hand tracking, combination stylus grab-enabled controller as interaction methods VR. The purpose was investigate suitability for object manipulation marking tasks planning. required with objects high accuracy creation landmarks. most preferred method. According subjective results, it considered appropriate because way that is similar use bare hands. objective mouse method accurate.
