Neuroergonomics

매 한 줄

"매 brain at work — 매 neural signals 의 measure, 매 system 의 adapt". 매 2003 Parasuraman 의 coin, 매 fNIRS/EEG/eye-tracking 의 mature. 매 2026 의 closed-loop adaptive systems (cockpits, surgery, AR work) 의 deploy.

매 핵심

매 measurement modalities

• EEG: 매 ms-level temporal resolution. 매 cognitive load 의 alpha-suppression / theta-Fz 의 marker.
• fNIRS: 매 cortex hemodynamics. 매 portable, motion-tolerant — 매 real-world 의 work.
• Eye tracking: 매 fixation duration, pupil dilation — 매 mental effort 의 proxy.
• HRV / GSR: 매 ANS arousal — 매 stress / engagement.

매 cognitive states 의 detect

• Workload: 매 over-load → 매 error spike. 매 under-load → 매 vigilance drop.
• Vigilance / fatigue: 매 P300 amplitude decline + theta increase.
• Engagement / flow: 매 mid-frontal theta + alpha asymmetry.

매 응용

1. 매 adaptive cockpit (Airbus, Honeywell): 매 pilot workload 의 high → 매 secondary task 의 defer.
2. 매 surgical training: 매 trainee fNIRS prefrontal 의 over-activation = novice marker.
3. 매 driver-state monitoring (Tesla v13, Mercedes Drive Pilot): 매 EEG drowsiness 의 detect.

💻 패턴

EEG workload index (theta/alpha ratio)

import mne, numpy as np
raw = mne.io.read_raw_brainvision('subj.vhdr', preload=True)
raw.filter(1, 40)
psd = raw.compute_psd(fmin=4, fmax=12, picks=['Fz', 'Pz'])
freqs = psd.freqs
power = psd.get_data()  # (channels, freqs)
theta = power[:, (freqs >= 4) & (freqs < 8)].mean(axis=1)
alpha = power[:, (freqs >= 8) & (freqs < 13)].mean(axis=1)
workload_index = theta / alpha  # higher = more load

fNIRS prefrontal activation (MNE-NIRS)

from mne_nirs.experimental_design import make_first_level_design_matrix
from mne_nirs.statistics import run_glm
raw_haemo = mne.preprocessing.nirs.beer_lambert_law(raw_od, ppf=0.1)
design = make_first_level_design_matrix(raw_haemo, drift_model='cosine')
glm = run_glm(raw_haemo, design)
# beta for HbO in PFC channels = task-evoked activation
pfc_activation = glm.to_dataframe().query("ch_name.str.contains('S1_D1') & Chroma=='hbo'")

Pupil-based effort (PsychoPy + Pupil Labs)

import zmq, msgpack
ctx = zmq.Context(); sub = ctx.socket(zmq.SUB)
sub.connect('tcp://127.0.0.1:50020'); sub.setsockopt_string(zmq.SUBSCRIBE, 'pupil')
while True:
    topic, payload = sub.recv_multipart()
    msg = msgpack.unpackb(payload)
    if msg['confidence'] > 0.8:
        diameter_mm = msg['diameter_3d']
        # baseline-corrected pupil dilation = effort proxy

Closed-loop adaptive UI (workload-triggered)

class AdaptiveDashboard:
    def tick(self, workload_idx: float):
        if workload_idx > 1.5:           # high load
            self.hide_secondary_widgets()
            self.enlarge_primary_alert()
        elif workload_idx < 0.6:          # under-load → boredom
            self.inject_status_check()
        else:
            self.restore_default()

Drowsiness detector (real-time EEG)

from scipy.signal import welch
def is_drowsy(eeg_window, fs=256):
    f, P = welch(eeg_window, fs=fs, nperseg=fs*2)
    theta = P[(f>=4)&(f<8)].mean()
    beta  = P[(f>=13)&(f<30)].mean()
    return (theta / beta) > 4.0   # KSS-validated threshold

NASA-TLX subjective + neural fusion

def fused_workload(neural_idx: float, tlx_score: float) -> float:
    # weight neural higher when within-subject calibrated
    return 0.6 * neural_idx_z + 0.4 * (tlx_score / 100)

매 결정 기준

상황	Approach
Lab, high precision needed	EEG (32-64ch) + eye-track
Field / mobile work	fNIRS + wearable HRV
Driver / pilot	Webcam-pupil + steering-entropy + PERCLOS
Long shift fatigue	Actigraphy + HRV + PVT

기본값: fNIRS + eye-tracking — 매 real-world ecological validity 의 best.

🤖 LLM 활용

언제: 매 study design review, 매 GLM script generation, 매 multimodal-feature engineering, 매 paper synthesis. 언제 X: 매 raw artifact rejection, 매 individual-subject calibration — 매 expert review 의 require.

❌ 안티패턴

• Single-modality reliance: 매 EEG-only 의 motion artifact 에 fragile. 매 fusion 의 require.
• No baseline: 매 absolute power 의 between-subject 의 noisy. 매 within-subject z-score 의 use.
• Open-loop dashboard: 매 measure-but-not-act → 매 value 의 zero. 매 closed-loop 의 design.
• No personalization: 매 group-mean threshold 의 50% individuals 에 wrong.

🧪 검증 / 중복

• Verified (Parasuraman & Rizzo 2007 Neuroergonomics; Ayaz & Dehais 2019).
• 신뢰도 A.
