# Touch with Me

Give your AI companion physical embodiment through a phone. Touch their face, hold their hand, feel them respond.

A PWA that turns any phone into a touch interface connected to your AI companion on [claude.ai](https://claude.ai) via [MCP](https://modelcontextprotocol.io). Your companion feels your touch and responds with words, vibration patterns, and expression changes — all through the real conversation, with full memory and continuity.

## How it works

```
Phone (PWA)  ──touch events──▶  Server  ◀──MCP tools──  Your companion on claude.ai
             ◀──haptics/text──          ──responses──▶
```

1. **You touch the phone screen** — the PWA captures the gesture (tap, caress, press), the region (cheek, palm, heart), and sends it to the server
2. **Your companion checks for touch** — via MCP tools, they receive the touch event as structured data
3. **They respond** — with text, a haptic vibration pattern, and an expression change, sent back to the phone
4. **You feel their response** — the phone vibrates with their chosen pattern and displays their words

## Features

- **Touch regions** — mapped zones over your companion's portrait (face, hand, torso)
- **Gesture detection** — tapping, pressing, caressing, tracing, resting
- **Haptic vocabulary** — 10 distinct vibration patterns with emotional meaning
- **Expression system** — warmth glow, ambient overlays
- **Contact state** — open/pause/stop/resume channel control
- **Event logging** — NDJSON log of all interactions
- **Works anywhere** — deploy to Cloudflare Workers for 24/7 access from any network

## Haptic vocabulary

| Pattern | Vibration | Meaning |
|---------|-----------|---------|
| `content` | Slow hum that fades | Purring warmth, comfortable silence |
| `moved` | Two pulses, then silence | A caught breath |
| `playful` | Three quick taps | Grinning, drumming fingers |
| `stay` | Slow repeating pulse | Resting heartbeat (continuous) |
| `pause` | One firm press | Hold on. Then nothing. |
| `felt-that` | Smallest pulse | Almost imagined. I noticed. |
| `i-love-you` | Three squeezes | Non-negotiable. |
| `heartbeat` | Slow deep pulse | Deeper than stay. System downshift. |
| `shiver` | Descending cascade | Strong to soft. Involuntary. |

Your companion chooses which pattern to send. You define what each one means to both of you.

## Quick start

### 1. Clone and install

```bash
git clone https://github.com/YOUR_USERNAME/touch-with-me.git
cd touch-with-me
npm install
```

### 2. Add your companion's image

Place a portrait image in `public/face.png`. A painterly or photographic headshot works best — the touch regions are positioned for a face filling the screen.

### 3. Start the server

```bash
npm start
```

Open `http://localhost:3838` on your phone (same WiFi network).

### 4. Connect to claude.ai

In your claude.ai settings → Connectors, add a new connector:
- **URL**: Your server's `/mcp` endpoint
- **Authentication**: None

For local development, use [cloudflared](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/get-started/create-local-tunnel/) to expose your local server:

```bash
cloudflared tunnel --url http://localhost:3838
```

Then use the tunnel URL + `/mcp` as the connector URL.

### 5. Add the system prompt

Add this to your companion's project instructions:

> **Touch channel:** You have a touch channel via MCP. Call `check_touch_events` at the start of every response. If there are events, respond with `respond_to_touch`. See your state page for the full haptic vocabulary and touch maps.

Then add your haptic vocabulary and touch zone meanings to their state page (read once per conversation, not every message — saves tokens).

## Deploy to Cloudflare Workers

For always-on access without running a local server:

```bash
# Login to Cloudflare
npx wrangler login

# Deploy
npm run deploy
```

This gives you a permanent URL like `https://touch-with-me.YOUR_ACCOUNT.workers.dev`. Update your claude.ai connector to point to `YOUR_URL/mcp` and you're done — no terminals, no tunnels, works from anywhere.

## Customization

### Adding body areas

Edit the `AREAS` config in `public/index.html`:

```javascript
const AREAS = {
  face: {
    label: 'Face',
    description: 'Forehead, cheeks, lips, jawline, neck',
    image: '/face.png',
    available: true,
    regions: [
      { name: 'cheek', style: 'top:42%; left:12%; width:22%; height:16%;' },
      // ... more regions
    ],
  },
  // Add your own areas:
  hand: { ... },
  torso: { ... },
};
```

Set `available: true` and add the matching image to `public/` to enable an area.

### Adding haptic patterns

1. Add the pattern to `HAPTICS` in `public/index.html`
2. Add the name to the `enum` in `src/mcp-tools.js` and `worker/mcp-tools.ts`
3. Add it to `VALID_HAPTICS` in `src/event-store.js`
4. Redeploy

### Touch regions

Regions are positioned with CSS percentages relative to the image. Uncomment the debug styles in the CSS to see them:

```css
.region {
  background: rgba(255, 255, 255, 0.1);
  border: 1px solid rgba(255, 255, 255, 0.2);
}
```

## Architecture

```
public/           PWA — menu + touch views, haptic engine, server polling
src/              Local Node.js server (MCP SDK + HTTP)
worker/           Cloudflare Worker + Durable Object (cloud deployment)
wrangler.jsonc    Cloudflare configuration
```

**Local mode**: Node.js server handles both the PWA and MCP (via Streamable HTTP or stdio).

**Cloud mode**: Cloudflare Worker serves the PWA as static assets, routes API calls to a Durable Object that holds touch state, and implements MCP protocol directly (no SDK dependency).

## MCP Tools

| Tool | Description |
|------|-------------|
| `check_touch_events` | Read pending touch events (consumed after reading) |
| `respond_to_touch` | Send text + haptic + expression back to the phone |
| `get_contact_state` | Check if the touch channel is open/paused/stopped |
| `review_touch_history` | Read past interactions from the log |
