DSI-VR300

The DSI-VR300 is the first-ever Active Dry EEG headset with an integrated VR Headset. It is a research-grade EEG system specifically designed for P300 applications and other research projects in the field of BCI (Brain-Computer Interface) and Neuropsychology where VR (virtual reality) integration is required. The DSI-VR300 comprises low output impedance Dry EEG Sensors that function even through thick hair, requiring no subject preparation or any conductive gels. These Dry EEG sensors can be individually adjusted to optimize contact impedance. The DSI-VR300 interfaces seamlessly with the HTC-Vive VR headset. A virtual reality specific API developed by Neurable allows integration of P300 elements into a VR environment.
