PiEEG XR Mask: EEG Brainwave Input for VR and Extended Reality

The PiEEG XR introduces a new EEG-based input method for virtual and extended reality environments. The device replaces standard face cushions with built-in electrodes to capture brain activity in real time. This approach targets developers, researchers, and consumers seeking direct neural control over VR applications.

EEG face cushion replaces standard headset padding for neural control

PiEEG designed the headset as a wearable accessory that fits into existing VR headsets like the Pico 4 Ultra. The system relies on ironbci for data processing, which records 250 data points per second to maintain high temporal resolution. Bluetooth connectivity enables wireless communication with compatible hardware without requiring additional cables.

The device operates in three distinct configurations. A standard PiEEG XR Mask replaces the original face cushion of supported headsets. A research kit pairs with ironbci for academic or development use. An all-in-one consumer version bundles everything into a single package for direct retail sale.

Native compatibility extends to VRChat, allowing users to apply brain signals directly within the platform. The system targets makers and researchers who need precise neural data alongside casual consumers exploring new interaction models. Wireless transmission via Bluetooth keeps the setup lightweight during extended sessions.
