The DSI-VR300 is a research-grade dry electrode EEG system specifically designed for P300 applications and VR integration. The system comprises of ultra-high impedance active Dry Sensor Interface (DSI) sensors that function through hair, requiring no skin preparation or conductive gels. Sensors can be individually adjusted to optimize contact impedance. The design interfaces seamlessly with the HTC-Vive VR headset. A virtual reality-specific API developed by Neurable allows for rapid integration of P300 elements into the VR environment.
The DSI VR300 is a fully integrated, adjustable, and comfortable dry electrode EEG headset with wireless triggering.
The DSI-7¡¯s practicality, portability, and high signal quality opens the door to taking numerous applications that require rapid and non-intrusive EEG recording. Such applications include:
