BCI + XR

BCI + XR combines extended reality with neural or physiological measurement, but the label needs careful qualification. Most products described as BCI + VR are EEG add-ons fitted to another company’s headset, including Looxid, DSI-VR300, PiEEG, and g.tec systems paired with Quest, or affect-sensing systems without EEG, such as Emteq and HP Omnicept. Galea is unusual because it synchronizes EEG, EOG, EMG, EDA, PPG, and eye tracking in one integrated rig. Meta Neural Band is different again: it is a wrist-worn sEMG interface that measures peripheral nerve and muscle activity, not a brain interface. This guide therefore exposes every sensor modality, compatible XR platform, and commercial status so brain signals are not confused with eye, face, cardiac, or peripheral-nerve measurements.
