q2 · i? · review · r3

Feasibility study of 10 non-medical students reviewed within the systematic review, comparing HTC Vive, Valve Index and Microsoft HoloLens interaction methods. Appendix A reports that "Simulation models with a physical controller allows has a higher ease of use and lower cognitive load than hand tracking gestures (limited to pinching)."

"Chan et al.61 compared the use of the HTC Vive controller-based examination, Valve Index “Knuckle” controller-based examination, Microsoft HoloLens gesture-based examination, and noted that participants found it difficult to familiarise with operation of the three different simulations, and that headsets were heavy, and voice commands were inaccurate."
