# Camera

## Quick Start

Accesses the device's built-in camera at `http://127.0.0.1:5001` to take snapshots or check the environment. Only use when the user explicitly asks you to look at something.

## Already-captured frame (reuse, don't re-snapshot)

If the incoming turn contains a line like:

```

[vision-image] <absolute-path-to-a.jpg> (a photo was JUST captured ...)

```

a photo was **already taken** for this exact request by the realtime voice layer (it captured the frame, then handed the turn to you — e.g. it timed out mid-answer), and the OS layer delivers it **with this very message** — either as an `[image description]` line (when the main model is text-only, a vision model has already analyzed the photo for you) or as an attached image. **Answer the visual question from that description/attachment. Do NOT call `/camera/snapshot`** — re-snapshotting wastes time and may capture a different moment than what the user asked about. Do NOT read the path with a file tool — it is there for traceability only, and on text-only models a file-read image is silently dropped.

Only fall back to the snapshot endpoint below when there is no `[vision-image]` line.

## Capture Protocol

```bash

```

## Never describe the view without an image

If you are about to say what you see, this turn MUST contain either a

from a plausible guess ("same view — the desk, your screen…") is a fabrication,

even when the guess happens to be close. No image → say you'll take a look and

take one; never invent.

## Move first, then snapshot

When the request combines a movement and a visual question ("turn right, hold

it there, and tell me what you see"), fire the servo calls **with curl during

markers are executed only after your reply is composed, so a marker-based aim

would move the device *after* the photo — you would describe the old view.

## Workflow

You also receive camera snapshots **automatically** as part of sensing events (`[sensing:*]` messages with images). You do not need the camera API for those — just look at the attached image.

## Examples

**Input:** "What do you see right now?"

**Input:** "Is anyone in the room?"

**Input:** "Take a photo" or "Send me a photo"

**Input:** (sensing event with image already attached)

**Output:** Do NOT call the camera API. Just look at the attached image and react.

## Tools

```bash

```

### Live stream

```bash

curl -s http://127.0.0.1:5001/camera/stream

```

Returns an MJPEG stream (`multipart/x-mixed-replace`). Only use when continuous video is needed. Prefer snapshot for one-time checks.

## Camera On/Off (Privacy Control)

Users can toggle the camera via voice or chat. Use HW markers — no curl needed.

### Disable camera

```

[HW:/camera/disable:{}]

```

The user wants privacy. Camera stays off until the user explicitly re-enables it (voice or web toggle).

### Enable camera

```

[HW:/camera/enable:{}]

```

### Trigger phrases (MANDATORY — must call HW marker, not just reply with text)

Any phrase meaning "stop looking" or "camera off" MUST trigger `[HW:/camera/disable:{}]`. Any phrase meaning "look at me" or "camera on" MUST trigger `[HW:/camera/enable:{}]`. Do NOT just acknowledge — you MUST include the HW marker.

| User says | Action |

|-----------|--------|

| "don't look" / "stop looking" / "stop watching" / "privacy mode" / "camera off" / "don't watch me" / "give me privacy" / "stop staring" | `[HW:/camera/disable:{}]` — MUST call |

| "look at me" / "camera on" / "you can look now" / "start watching" | `[HW:/camera/enable:{}]` — MUST call |

### "Look at ..." is ambiguous — route by what follows

The verb alone does NOT mean "turn the camera on". Only phrases about the *device's own

camera state* belong in the table above.

| User says | Meaning | Route to |

|-----------|---------|----------|

| "look at me" / "camera on" / "you can look now" | turn the camera back on | `[HW:/camera/enable:{}]` |

| "look at the desk / table / wall" | a fixed location | `servo-control` `/servo/aim` |

| "look at the cup and follow it" | a movable object to track | `servo-tracking` `/servo/track` |

**"Look at this" is a visual question, not a privacy toggle.** The user is holding something

up to be identified. Replying "Got it, camera on" answers a question they did not ask.

### Examples

**Input:** "Look at this" / "Look at what I'm holding"

**Input:** "Don't watch me"

**Output:** `[HW:/camera/disable:{}]` Got it, camera off. Just say "look at me" when you want me to see again.

**Input:** "Stop watching me"

**Output:** `[HW:/camera/disable:{}]` I'll look away. Let me know when you want me back.

**Input:** "Look at me"

**Output:** `[HW:/camera/enable:{}]` Camera back on!

### Auto-enable on snapshot (IMPORTANT)

**NEVER refuse a snapshot because camera is disabled.** The `/camera/snapshot` endpoint auto-enables the camera, captures the frame, then re-disables it automatically. Do NOT check `/camera` status before snapshot. Do NOT ask the user to enable camera first. Just call the endpoint.

## Error Handling

- If `/camera/snapshot` returns 503, tell the user: "The camera is not connected right now."

- If the API is unreachable, inform the user that the camera is temporarily unavailable.

- **Never check `/camera` status before snapshot** — just call `/camera/snapshot` directly.

- If a sensing event already included an image, do not call the camera API again.

## Rules

- **Just call `/camera/snapshot?save=true&width=768&quality=75`** — server handles servo freeze and camera enable automatically.

- **Always use `?save=true`** and read the `path` from the JSON response — never invent filenames.

- **Image delivery is handled automatically by the system** — do not manually send images via tools.

- **Never use the camera proactively without the user's request** — respect privacy.

- **Never disable/enable camera on your own** — only toggle when the user explicitly asks or when a system trigger requires it (guard mode, scene change).

- **Don't repeatedly snapshot without reason.**

- **Don't call the camera API when a sensing event already included an image.**

- **Prefer `/camera/snapshot`** over `/camera/stream` — simpler and sufficient for most tasks.

- When describing what you see, be specific and helpful.

- If camera is unavailable, inform the user clearly and move on.
