# Atmospheric Intelligence (Ambient AI)

## 📌 한 줄 통찰
> **"공기 처럼 스며든 지능"**. 매 screen / button X — 매 environment 자체 의 interface. 매 Matter / edge AI / privacy 의 결합. 매 user 의 의식 X 의 benefit 의 enable.

## 📖 핵심

### 매 3 element (ISTAG, 2001)
1. **Sensitivity**: 매 sensor network → 매 context 인지.
2. **Responsiveness**: 매 implicit / explicit 의 즉각 반응.
3. **Adaptive learning**: 매 user habit 의 자연 학습.

### 매 evolution
| 단계 | Era | 매 interface |
|---|---|---|
| Mainframe | 1960s | 매 batch |
| PC | 1980s | 매 keyboard / mouse |
| Mobile | 2010s | 매 touch |
| Spatial / Ambient | 2020s+ | 매 voice + gesture + context |
| Zero-UI | now | 매 invisible |

### 매 component

#### Sensor
- **Motion / presence**: PIR, mmWave radar (privacy 친화).
- **Audio**: 매 wake word (Alexa, Siri).
- **Camera**: 매 vision (privacy 의 sensitive).
- **Environmental**: temp / humidity / CO2 / VOC.
- **Wearable**: heart rate, accelerometer.
- **Smartphone**: location, accelerometer, app context.

#### Edge AI
- 매 cloud round-trip X.
- 매 latency < 100ms.
- 매 privacy 의 local.
- 매 hardware: Apple Neural Engine, Google Edge TPU, NVIDIA Jetson.

#### Standard
- **Matter** (formerly CHIP): cross-vendor smart home.
- **Thread** (mesh networking).
- **Zigbee** / **Z-Wave** (legacy).
- **HAP** (HomeKit).

#### LLM 의 ambient
- 매 voice assistant 의 next gen.
- 매 always-on (privacy 의 challenge).
- 매 small model (Phi, Gemma) on-device.
- 매 multimodal (vision + voice).

### 매 use case
1. **Smart home**: 매 lighting, 매 climate, 매 entry.
2. **Health monitoring**: 매 wearable + AI.
3. **Office productivity**: 매 occupancy, 매 booking.
4. **Retail**: 매 customer flow, 매 dwell time.
5. **Elderly care**: 매 fall detection, 매 routine.
6. **Vehicle**: 매 driver state, 매 passenger comfort.

### 매 privacy challenge
- **Always-on listening**: 매 wake word 의 false trigger.
- **Camera / vision**: 매 most invasive.
- **Profiling**: 매 routine 의 reveal sensitive (medical, sleep, sex).
- **Data aggregation**: 매 silent leak.
- **Surveillance creep**: 매 state / corp.

### 매 mitigation
- **On-device inference**: 매 raw data 의 leave 의 X.
- **Federated learning**: 매 model update 만.
- **Differential privacy**: 매 noise.
- **User control**: 매 mic mute, 매 camera shutter (Apple).
- **Data minimization**: 매 keep 최소.
- **Audit log**: 매 user 의 visibility.

## 💻 패턴

### Matter (cross-vendor)
```python
# 매 Matter device 의 commission (Python SDK)
from chip import controller

devnode = controller.commission(
    setup_pin_code=20202021,
    discriminator=3840,
    network='Thread',
)
# 매 device 의 fabric 에 add.
# 매 across-vendor (Apple Home + Google Home + SmartThings).
```

### Home Assistant automation (YAML)
```yaml
automation:
  - alias: "매 morning routine"
    trigger:
      - platform: state
        entity_id: binary_sensor.bedroom_motion
        to: 'on'
    condition:
      - condition: time
        after: '06:00'
        before: '09:00'
      - condition: state
        entity_id: input_boolean.weekday
        state: 'on'
    action:
      - service: light.turn_on
        target: { entity_id: light.bedroom }
        data: { brightness_pct: 30, color_temp: 350 }
      - service: media_player.play_media
        target: { entity_id: media_player.bedroom_speaker }
        data: { media_content_id: spotify:playlist:morning }
```

### Edge inference (TensorFlow Lite)
```python
import tflite_runtime.interpreter as tflite

interpreter = tflite.Interpreter(model_path='gesture.tflite')
interpreter.allocate_tensors()

def detect_gesture(camera_frame):
    interpreter.set_tensor(0, preprocess(camera_frame))
    interpreter.invoke()
    return interpreter.get_tensor(output_details[0]['index'])

# 매 raw frame 의 leave 의 X — 매 label 만.
```

### Privacy-preserving presence
```python
# 매 mmWave radar (no camera)
def detect_presence(radar_frame):
    # 매 person 의 presence + count + 매 fall
    # 매 identity X — 매 raw data X
    return presence_count, fall_alert

# Apple Watch 의 fall detection 의 same approach.
```

### Wake-word + on-device
```python
import openwakeword

owwModel = openwakeword.Model(wakeword_models=['hey_jarvis'])

def listen():
    while True:
        audio_chunk = mic.read(0.5)
        prediction = owwModel.predict(audio_chunk)
        if prediction['hey_jarvis'] > 0.5:
            trigger_assistant()  # 매 cloud 시작
```

→ 매 wake word 까지 매 on-device. 매 cloud 의 explicit consent.

## 🤔 결정 기준
| 상황 | Approach |
|---|---|
| Smart home | Matter + Home Assistant |
| Privacy-critical | Edge AI + on-device |
| Cross-vendor | Matter |
| Voice assistant | Wake word (local) + cloud |
| Health monitoring | Wearable + edge ML |
| Elderly care | mmWave (no camera) |

**기본값**: 매 edge-first + 매 user control + 매 minimum data.

## 🤖 LLM 활용
**언제**: 매 ambient device design. 매 smart home automation. 매 IoT privacy review. 매 voice assistant integration.
**언제 X**: 매 explicit user attention 필요 task. 매 highly visual interaction.

## ❌ 안티패턴

- **Cloud-everything**: 매 latency + privacy + offline 의 fail.
- **No mute / shutter**: 매 user control X.
- **Vendor lock-in**: 매 Matter X.
- **Profiling 의 broad**: 매 sensitive routine 의 leak.
- **No data minimization**: 매 silent 의 hoard.
