👁️ Blink Metrics

BlinkNow

1 = blink at sample, 0 = no blink

BlinkFrequency

Blinks per second

BlinkRate

Blinks per minute

BlinkRateExcess

Blink rate minus baseline (from calibration)

🧘 Calm & Cognitive Load

Calm

Alpha relative, avg AF7–AF8

CognitiveLoad

z(θAF7+θAF8) − z(αAF7+αAF8)

⚙️ Engagement / Fatigue

EngagementIndex

(β sum) / (α sum + θ sum) in linear power

EEGDisengagement

(α sum + θ sum) / β sum in linear power

DFI

Disengagement/Fatigue Index (0.6×EEG + 0.4×BlinkRateExcess)

MCSI

(EngagementIndex − DFI + 1) / 2, in [0, 1]
