An Evaluation Testbed for Locomotion in Virtual Reality

A common operation performed in Virtual Reality (VR) environments is locomotion. Although real walking can represent a natural and intuitive way to manage displacements such environments, its use generally limited by the size of area tracked VR system (typically, room) or requires expensive technologies cover particularly extended settings. number approaches have been proposed enable effective explorations VR, each characterized different hardware requirements costs, capable provide levels usability performance. However, lack well-defined methodology for assessing comparing available makes it difficult identify, among various alternatives, best solutions selected application domains. To deal with this issue, paper introduces novel evaluation testbed which, building on outcomes many separate works reported literature, aims support comprehensive analysis considered design space. An experimental protocol collecting objective subjective measures proposed, together scoring able rank locomotion based weighted set requirements. Testbed usage illustrated case requesting select technique adopt given scenario.
