Through a comparative study utilising Virtual Reality and Haptic Feedback, this study explores the implications of VR-based skill training, particularly on the effectiveness and skill retention of this training. By comparing the outcomes of two training sessions using a VR simulation to conduct a CPR-training demonstration, this thesis will offer insights on how passive and active haptic feedback can affect these outcomes.  The experimental design for this thesis involves several aspects, namely feedback from CPR experts, considerations for virtualising training stemming from process-virtualisation theory, and physical prototyping of a haptic feedback system which included passive haptic feedback in the form of a minimalistic mannequin with built-in resistance, and active haptic feedback through the use of motor vibrations and wizard of oz techniques. The key findings of this research imply an improvement in proper skill acquisition and skill retention in CPR when using a minimalistic haptic feedback system. Our system resulted in a higher level of user engagement, an overall better user experience, a higher standard of technique, faster time to completion, improved user confidence, and most importantly, higher skill retention over a gap-period. This research therefore contributes to a better understanding of how skill-training can be made more accessible throughout the world with the use of VR while still maintaining a high standard of the skill. Through the virtual reality solutions developed and provided by NordicMojo, whom we have collaborated with in order to conduct this research, this thesis will have an immediate impact on offering higher standards of  accessible CPR training around the world, which will contribute to an increased number of lives saved throughout the globe.
