Physiological measurements

The alternative is to attach sensors to the user so that physiological measurements are automatically obtained before, during, and after the VR session. The data can be obtained continuously without interrupting the user or asking him to pay attention to symptoms. There may, however, be some discomfort or fear associated with the placement of sensors on the body. Researchers typically purchase a standard sensing system, such as the Biopac MP150, which contains a pack of sensors, records the data, and transmits them to a computer for analysis.

Some physiological measures that have been used for studying VR sickness are:

A recent comparison of physiological measures and questionnaires appears in [59], and it is even concluded that one can determine whether a person is experiencing VR from the physiological data alone.
