The requirement is for a portable VR headset, capable of capturing a wide array of physiological data including eye tracking, EEG, muscle activation, galvanic skin response, heart-rate and behavior, with 100% dry sensors. This is to minimize the burden of using different systems to capture the variety of physiological data, and the subsequent interference that will occur combining systems that do not work well together (such as a known difficulty capturing EEG during virtual reality exposure if the electrodes are not built into the system). Additionally, the need for dry sensors is due to the environment in which the testing will occur, which will not allow the use of gel.
