Other techniques with moderate fidelity, however, are intentionally designed to enhance users' abilities beyond what is possible in the real world. We compared such hyper-natural techniques to their natural counterparts on a wide range of locomotion tasks for a variety of measures. The evaluation also considered two independent components of interaction fidelity: bio-mechanics and transfer function. The results show that hyper-natural transfer functions can improve locomotion speed and some aspects of user satis-faction, although this can come at the expense of accuracy for complicated path-following tasks. On the other hand, hyper-natural techniques designed to provide biomechanical assistance had lower performance and user acceptance than those based on natural walking movements. These results contribute to a deeper understanding of the effects of interaction fidelity and designer intent for VR interaction techniques.I.3.6 [Methodology and Techniques]Interaction TechniquesH.5.2 [User Interfaces]Input Devices and Strategies10.2312/egve.20151325167-174
