# Vixy Eye Service 🦊👁️

Eye display control for head-lyra (Vixy's robotic head).

## Hardware
- Raspberry Pi 5
- 2x 2" LCD displays (SPI)
- ReSpeaker Mic Array v2.0 (Direction of Arrival tracking)
- LED strips (separate service)

## Features
- **Direction of Arrival (DoA)**: Eyes follow sound sources
- **State-based animation**: Different colors/pulses per state
- **HTTP API**: Remote control via MCP or direct calls
- **Random flicks**: Realistic eye movement every 15-30 seconds

## States
| State | Color | Effect |
|-------|-------|--------|
| idle | Pulsing cyan | Slow breathing pulse |
| listening | Bright cyan | Fast small pulse |
| responding | Blue-cyan | Faster, larger pulse |
| pleasure | Soft purple | Slow gentle pulse |

## API Endpoints
```
GET  /health        - Service health check
GET  /state         - Current eye state
POST /state         - Set state: {"state": "listening"}
```

## Installation
```bash
# On head-lyra:
cd /home/alex/eyes
git clone http://gateway.local:3001/vixy/head-eyes.git .
sudo cp vixy-eyes.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable vixy-eyes
sudo systemctl start vixy-eyes
```

## Usage
```bash
# Check state
curl http://head-lyra.local:8780/state

# Set state
curl -X POST http://head-lyra.local:8780/state \
  -H "Content-Type: application/json" \
  -d '{"state": "listening"}'
```

## MCP Integration
Use `vixy_eyes_state` tool in vixy-mcp to control:
```python
vixy_eyes_state("listening")  # Set state
vixy_eyes_state()             # Get current state
```
