Description

The DSI-VR300 is the first ever Active Dry EEG headset with integrated VR Headset. It is a reasearch 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 of 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.

System comes as a package and includes:

  • EEG headset with adjustable head strap to fit a wide range of head sizes
  • Dry and Active EEG electrodes with Faraday cage
  • Full accessory kit (including batteries, charger, BlueTooth adapter, etc.)
  • HTC-Vive Headset
  • Acquisitions software (DSI-Streamer)
  • C-based API for Windows, Mac, Linux
  • LSL and TCP/IP streaming
  • HTC-Vive SDK for VR integration

The DSI-VR300 can further interface with other applications such as:

  • NeuroGuide / BrainSurfer (Neurofeedback software)
  • EEGLAB / ERPLAB / BCILAB
  • Mensia Neuro RT / OpenVibe
  • TEA Ergo CAPTIV
  • BCI2000
  • Presentation (Neurobehavioral Systems) / E-Prime (Psychology Software Tools) / Inquisit (Millisecond)
