Neural Signals
Brainwave activity measured via EEG provides direct insight into cognitive state — focus, relaxation, mental fatigue, and cognitive overload.
Accepted Fields
| Field | Type | Unit | Description |
|---|---|---|---|
eeg_alpha_power | float | uV² | Alpha band power (8-13 Hz) — associated with relaxed alertness |
eeg_beta_power | float | uV² | Beta band power (13-30 Hz) — associated with active thinking and stress |
eeg_theta_power | float | uV² | Theta band power (4-8 Hz) — associated with drowsiness and deep relaxation |
cognitive_load | float | 0.0 - 1.0 | Estimated cognitive load from EEG analysis |
Status
Neural signals are accepted and stored by the API. Fusion into the stress score is planned for a future release.
Compatible Devices
- Muse 2 / Muse S — consumer EEG headband
- Emotiv EPOC — research-grade EEG
