The DSI-7 from Wearable Sensing is a wireless, dry electrode EEG headset designed for rapid deployment and high signal fidelity. With an average setup time of under one minute, the DSI-7 is ideal for researchers seeking a lightweight, easy-to-use solution for studies in VR/AR environments, mobile experiments, or naturalistic settings outside the lab.
Featuring 7 dry EEG sensors (customizable positions) and 2 earclip references, the system provides targeted coverage of frontal, central, and posterior brain regions. A 4-bit trigger input allows for synchronization with external devices such as eye trackers, motion capture systems, and other experimental hardware.
Despite its minimalist profile, the DSI-7 retains the research-grade performance of larger systems and is trusted globally across fields including neurofeedback, neuromarketing, brain-computer interfaces, and neuroergonomics.
The system comes as a package and includes:
- EEG headset with an 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.)
- 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)
System Features
- High-Quality Dry EEG Signals
The DSI-7’s patented Dry Sensor Interface achieves over 90% correlation with traditional wet EEG systems, offering reliable, gel-free recordings. - Fully Wireless and Wearable
With built-in amplifiers, digitizers, wireless transmission, onboard storage, and power, the DSI-7 is a true mobile EEG system—no tethering or external hardware required. - Ultra-Rapid Setup
Quick to don in under 1 minute, even on thick or curly hair. Perfect for studies requiring high throughput or participant comfort. - Custom Sensor Placement
Electrode positions can be configured to suit specific experimental needs, offering flexibility across cognitive, affective, and sensorimotor applications. - Comfortable and Lightweight
Foam padding, adjustable straps, and an ergonomic frame allow the system to be worn comfortably for sessions lasting up to 8 hours. - Motion and Electrical Artifact Rejection
Designed with a built-in Faraday cage and patented common-mode follower circuitry, the DSI-7 minimizes noise from movement and environmental interference. - Data Acquisition and API Access
Includes DSI-Streamer (free, unlimited licenses) for data acquisition and export to .CSV and .EDF formats. A free C-based API supports custom integration on Windows, macOS, Linux, and ARM systems. - Trigger Synchronization
A 4-bit trigger input supports precise timing and integration with a range of external research devices. - Cognitive State Classification
Compatible with QStates, a machine learning-based analysis tool for cognitive state monitoring, including engagement, workload, and fatigue. - Fast Cleaning and Turnaround
Cleans in under 1 minute with 70% isopropyl alcohol. Dry and ready for reuse in minutes.
