Pavilion: 매 each country / sponsor.
Signature pavilions (8): 매 Japanese expert curated.

매 tech showcase

Flying cars (eVTOL demo).
Avatar robots.
AI translation (real-time multi-lingual).
Sustainable construction (timber).
AR / VR experiences.
IoT cashless.

매 응용 (lessons for tech)

Immersive media design.
AR / VR at scale.
Multilingual UX.
Sustainable infra.
Crowd flow (computer vision).
Cashless / digital ID.

💻 패턴 (응용 lessons)

Multilingual real-time translation

def realtime_translate(audio_stream, target_lang):
    """매 Expo-style booth interaction."""
    transcript = whisper.transcribe(audio_stream)
    translated = translate(transcript, target_lang)
    tts = synthesize(translated, target_lang)
    return tts

Crowd flow ML

def predict_pavilion_wait(historical, weather, time_of_day):
    """매 wait time prediction."""
    features = encode([historical, weather, time_of_day])
    return wait_time_model.predict(features)

Cashless venue (digital ID)

class ExpoPay {
    async pay(amount: number, vendor: string) {
        const token = await getDigitalIDToken();
        return fetch('/pay', { method: 'POST', headers: { Authorization: `Bearer ${token}` }, body: JSON.stringify({ amount, vendor }) });
    }
}

AR pavilion experience

import { ARSession } from '@react-three/xr';

function PavilionAR() {
    return (
        <ARSession>
            <ambientLight intensity={0.5} />
            <Scene model="pavilion-content.glb" />
            <Hotspot position={[0, 1, -2]} info="Future city design" />
        </ARSession>
    );
}

Sustainable timber engineering (Grand Ring)

# 매 wood vs concrete CO2
def co2_footprint(material, mass_kg):
    factors = {'concrete': 0.1, 'steel': 1.85, 'cross_laminated_timber': -1.0}  # 매 CLT 의 carbon sink
    return mass_kg * factors[material]

Visitor flow heatmap

def crowd_density(camera_feed):
    """매 head detection + heatmap."""
    heads = detect_heads(camera_feed)
    H, W = camera_feed.shape[:2]
    density = np.zeros((H, W))
    for h in heads:
        density[h.y, h.x] += 1
    return gaussian_filter(density, sigma=10)

Real-time queue management

def dynamic_queue(pavilion, current_wait):
    if current_wait > 90:
        suggest_alternatives(pavilion.theme)
        offer_virtual_queue()
    elif current_wait > 60:
        recommend_off_peak()
    return current_wait

Avatar telepresence

class TelepresenceAvatar:
    """매 remote operator → 매 robot guide."""
    def __init__(self, robot):
        self.robot = robot
    
    def operate(self, operator_video, operator_audio):
        self.robot.face_display.show(operator_video)
        self.robot.speakers.play(operator_audio)
        self.robot.move(operator_command)

매 결정 기준 (응용)

상황	Approach
Tourist tech showcase	Immersive AR/VR
Multilingual venue	Real-time translation
Large crowd	CV flow + dynamic queue
Sustainable build	Timber structural
Payments	Digital ID + cashless

기본값: 매 Expo lessons → 매 immersive + multilingual + crowd-aware + sustainable.
