Evaluating VR Systems 

Virtual and augmented reality, both as technology and software medium, often require extensive evaluation to determine whether a piece of hardware or software is effective at achieving the goals they may seek to achieve. While many may ask questions that are specific to these goals, there are many standardized metrics and questionnaires from the literature that may be useful for evaluating different aspects of usability. A brief overview of some of these are given here.
