Measuring the human side of virtual reality

The quality of experience (QoE) of any virtual environment is important to its users; if its QoE is too low, users will cease using the VE. Measuring QoE requires measuring users' responses to the VE. There are three main methods for assessing humans in a VE: subjective, performance, and physiological. Each method lets the researcher collect different types of information: user attitude towards a VE, whether the user can complete a task, and whether a VE poses a health danger towards the user. While many virtual researchers also measure telepresence, there is some controversy to its real correlation with QoE.
