||||
- Service discovery
|
||||
- Load balancing
|
||||
- Circuit breaking
|
||||
- Observability
|
||||
|
||||
2. **Message Queue**: Consider adding a message queue (Kafka, RabbitMQ) for:
|
||||
- Async processing
|
||||
- Event streaming
|
||||
- Decoupling services
|
||||
- Scalability
|
||||
|
||||
3. **API Gateway**: Consider adding an API gateway (Kong, AWS API Gateway) for:
|
||||
- Rate limiting
|
||||
- Authentication
|
||||
- Request routing
|
||||
- API versioning
|
||||
|
||||

|
||||
```bash
|
||||
curl -X POST http://localhost:8081/v1/sessions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"tenant_id": "default",
|
||||

||||
|
||||
## Notes
|
||||
|
||||
- All mock services are functional and can be tested independently
|
||||
- Banking tools have fallback to mock data if service unavailable
|
||||
- WebRTC gateway is ready but needs full signaling implementation
|
||||
- Widget is fully functional for text chat (voice requires WebRTC completion)

# Unreal Engine Avatar Setup
|
||||
|
||||
This directory contains the Unreal Engine project for the Virtual Banker avatar.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Unreal Engine 5.3+ (or 5.4+ recommended)
|
||||
- PixelStreaming plugin enabled
|
||||
- Digital human character asset (Ready Player Me, MetaHuman, or custom)
|
||||
|
||||
## Setup Instructions
|
||||
|
||||
### 1. Create Unreal Project
|
||||
|
||||
1. Open Unreal Engine Editor
|
||||
2. Create new project:
|
||||
- Template: Blank
|
||||
- Blueprint or C++: Blueprint (or C++ if custom code needed)
|
||||
- Target Platform: Desktop
|
||||
- Quality: Maximum
|
||||
- Raytracing: Enabled (optional, for better quality)
|
||||
|
||||
### 2. Enable PixelStreaming
|
||||
|
||||
1. Edit → Plugins
|
||||
2. Search for "Pixel Streaming"
|
||||
3. Enable the plugin
|
||||
4. Restart Unreal Editor
|
||||
|
||||
### 3. Import Digital Human
|
||||
|
||||
1. Import your digital human character:
|
||||
- Ready Player Me: Use their Unreal plugin
|
||||
- MetaHuman: Use MetaHuman Creator
|
||||
- Custom: Import FBX/glTF with blendshapes
|
||||
|
||||
2. Set up blendshapes for visemes:
|
||||
- Import viseme blendshapes (aa, ee, oh, ou, mbp, etc.)
|
||||
- Map to animation system
|
||||
|
||||
### 4. Configure PixelStreaming
|
||||
|
||||
1. Edit → Project Settings → Plugins → Pixel Streaming
|
||||
2. Configure:
|
||||
- Streamer Port: 8888
|
||||
- WebRTC Port Range: 8888-8897
|
||||
- Enable WebRTC
|
||||
|
||||
### 5. Set Up Animation Blueprint
|
||||
|
||||
1. Create Animation Blueprint for avatar
|
||||
2. Set up state machine:
|
||||
- Idle
|
||||
- Speaking (viseme-driven)
|
||||
- Gesturing
|
||||
- Expressions
|
||||
|
||||
3. Connect viseme blendshapes to animation graph
|
||||
|
||||
### 6. Create Control Blueprint
|
||||
|
||||
1. Create Blueprint Actor for avatar control
|
||||
2. Add functions:
|
||||
- SetVisemes(VisemeData)
|
||||
- SetExpression(Valence, Arousal)
|
||||
- SetGesture(GestureType)
|
||||
- SetGaze(Target)
|
||||
|
||||
### 7. Build and Package
|
||||
|
||||
1. Package project for Linux (for server deployment):
|
||||
- File → Package Project → Linux
|
||||
- Or use command line:
|
||||
```
|
||||
UnrealEditor-Cmd.exe -run=UnrealVersionSelector -project="path/to/project.uproject" -game -cook -package -build
|
||||
```
|
||||
|
||||
## Deployment
|
||||
|
||||
The packaged Unreal project should be deployed to a GPU-enabled server with:
|
||||
- NVIDIA GPU (RTX 3090+ recommended)
|
||||
- CUDA drivers
|
||||
- Sufficient VRAM (8GB+ per instance)
|
||||
|
||||
## Integration
|
||||
|
||||
The renderer service (`avatar/renderer/service.go`) controls Unreal instances via:
|
||||
- Process management (start/stop instances)
|
||||
- WebSocket communication (animation parameters)
|
||||
- PixelStreaming WebRTC streams
|
||||
|
||||
## Notes
|
||||
|
||||
- Each active session requires one Unreal instance
|
||||
- GPU resources should be allocated per instance
|
||||
- Consider using Unreal's multi-instance support for scaling

|
||||
## Data Flow
|
||||
|
||||
### Voice Turn Flow
|
||||
|
||||
1. **User speaks** → Widget captures audio via microphone
|
||||
2. **Audio stream** → WebRTC gateway → ASR service
|
||||
3. **ASR** → Transcribes to text (partial + final)
|
||||
4. **Orchestrator** → Sends transcript to LLM with context
|
||||
5. **LLM** → Generates response + tool calls + emotion tags
|
||||
6. **TTS** → Converts text to audio stream
|
||||
7. **Avatar** → Generates visemes, expressions, gestures
|
||||
8. **Widget** → Plays audio, displays captions, animates avatar
|
||||
|
||||
### Text Turn Flow
|
||||
|
||||
1. **User types** → Widget sends text message
|
||||
2. **Orchestrator** → Processes message (same as step 4+ above)

||||
|
||||
```
|
||||
http://localhost:8082
|
||||
```
|
||||
|
||||
## Production Deployment
|
||||
|
||||
### Environment Variables
|
||||
|
||||
**Backend API:**
|
||||
```bash
|
||||
DATABASE_URL=postgres://user:pass@host:5432/db
|
||||
REDIS_URL=redis://host:6379
|
||||
PORT=8081
|
||||
```
|
||||
|
||||
**Widget CDN:**
|
||||
- Deploy to CDN (Cloudflare, AWS CloudFront, etc.)
|
||||
- Configure CORS headers
|
||||
- Enable gzip compression
|
||||
|
||||
### Docker Compose Production
|
||||
|
||||
```yaml
|
||||
services:
|
||||
virtual-banker-api:
|
||||
image: your-registry/virtual-banker-api:latest
|
||||
environment:
|
||||
- DATABASE_URL=${DATABASE_URL}
|
||||
- REDIS_URL=${REDIS_URL}
|
||||
deploy:
|
||||
replicas: 3
|
||||
resources:
|
||||
limits:
|
||||
cpus: '2'
|
||||
memory: 2G
|
||||
```
|
||||
|
||||
### Kubernetes Deployment
|
||||
|
||||
Example deployment:
|
||||
|
||||
```yaml
|
||||
apiVersion: apps/v1
|
||||
kind: Deployment
|
||||
metadata:
|
||||

|
||||
app: virtual-banker-api
|
||||
template:
|
||||
metadata:
|
||||
labels:
|
||||
app: virtual-banker-api
|
||||
spec:
|
||||
containers:
|
||||

|
||||
cpu: "1"
|
||||
limits:
|
||||
memory: "2Gi"
|
||||
cpu: "2"
|
||||
```
|
||||
|
||||
## Scaling
|
||||
|
||||
### Horizontal Scaling
|
||||
|
||||
- **API Service**: Stateless, scale horizontally
|
||||
- **Widget CDN**: Use CDN for global distribution
|
||||
- **Avatar Renderer**: GPU-bound, scale based on concurrent sessions
|
||||
|
||||
### Vertical Scaling
|
||||
|
||||
- **Database**: Increase connection pool, add read replicas
|
||||
- **Redis**: Use Redis Cluster for high availability
|
||||
- **Avatar Renderer**: Allocate more GPU resources
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Health Checks
|
||||
|
||||
- API: `GET /health`
|
||||
- Widget: `GET /health` (nginx)
|
||||
|
||||
### Metrics
|
||||
|
||||
- Session creation rate
|
||||
- Active sessions
|
||||
- API latency
|
||||
- Error rates
|
||||
- Avatar render queue
|
||||
|
||||
### Logging
|
||||
|
||||
- Structured logging (JSON)
|
||||
- Log aggregation (ELK, Loki, etc.)
|
||||
- Audit logs for compliance
|
||||
|
||||
## Security
|
||||
|
||||
### Network
|
||||
|
||||
- Use internal networks for service communication
|
||||
- Expose only necessary ports
|
||||
- Use TLS for external communication
|
||||
|
||||
### Secrets
|
||||
|
||||
- Store secrets in secret management (Vault, AWS Secrets Manager)
|
||||
- Rotate tokens regularly
|
||||
- Use ephemeral tokens for sessions
|
||||
|
||||
### Compliance
|
||||
|
||||
- Enable audit logging
|
||||
- Implement data retention policies
|
||||
- PII redaction in logs
|
||||
- Encryption at rest and in transit
|
||||
|
||||
## Backup & Recovery
|
||||
|
||||
### Database
|
||||
|
||||
- Regular PostgreSQL backups
|
||||
- Point-in-time recovery
|
||||
- Test restore procedures
|
||||
|
||||
### Redis
|
||||
|
||||
- Enable persistence (AOF/RDB)
|
||||
- Regular snapshots
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Session creation fails:**
|
||||
- Check database connection
|
||||
- Verify tenant exists
|
||||
- Check JWT validation
|
||||
|
||||
**Widget not loading:**
|
||||
- Check CORS configuration
|
||||
- Verify CDN is accessible
|
||||
- Check browser console for errors
|
||||
|
||||
**Avatar not displaying:**
|
||||
- Verify WebRTC connection
|
||||
- Check avatar renderer service
|
||||
- Verify GPU resources available

|
||||
<script src="https://cdn.example.com/virtual-banker/widget.js"
|
||||
data-tenant-id="your-tenant-id"
|
||||
data-user-id="user-123"
|
||||
data-auth-token="jwt-token"
|
||||
data-api-url="https://api.example.com"
|
||||
data-avatar-enabled="true"></script>
|
||||
<div id="virtual-banker-widget"></div>
|
||||
```
|
||||

## Programmatic API
|
||||
|
||||
### Methods
|
||||
|
||||
```javascript
|
||||
// Open widget
|
||||
window.VirtualBankerWidgetAPI.open();
|
||||
|
||||
// Close widget
|
||||
window.VirtualBankerWidgetAPI.close();
|
||||
|
||||
// Minimize widget
|
||||
window.VirtualBankerWidgetAPI.minimize();
|
||||
|
||||
// Set context (page/route information)
|
||||
window.VirtualBankerWidgetAPI.setContext({
|
||||
route: '/account',
|
||||
accountId: 'acc-123',
|
||||
productId: 'prod-456'
|
||||
});
|
||||
|
||||
// Update authentication token
|
||||
window.VirtualBankerWidgetAPI.setAuthToken('new-jwt-token');
|
||||
```
|
||||
|
||||
## PostMessage Events
|
||||
|
||||
Listen for widget events from the parent window:
|
||||
|
||||
```javascript
|
||||
window.addEventListener('message', (event) => {
|
||||
if (event.data.source === 'virtual-banker-widget') {
|
||||
switch (event.data.type) {
|
||||
case 'ready':
|
||||
console.log('Widget is ready');
|
||||
break;
|
||||
|
||||
case 'session_started':
|
||||
console.log('Session ID:', event.data.payload.sessionId);
|
||||
break;
|
||||
|
||||
case 'action_requested':
|
||||
console.log('Action:', event.data.payload.action);
|
||||
console.log('Params:', event.data.payload.params);
|
||||
// Handle action (e.g., open ticket, schedule appointment)
|
||||
break;
|
||||
|
||||
case 'action_completed':
|
||||
console.log('Action completed:', event.data.payload);
|
||||
break;
|
||||
|
||||
case 'handoff_to_human':
|
||||
console.log('Handoff reason:', event.data.payload.reason);
|
||||
// Show human agent interface
|
||||
break;
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
## Sending Messages to Widget
|
||||
|
||||
Send commands to the widget from the parent window:
|
||||
|
||||
```javascript
|
||||
const widget = document.getElementById('virtual-banker-widget');
|
||||
if (widget && widget.contentWindow) {
|
||||
widget.contentWindow.postMessage({
|
||||
type: 'open',
|
||||
source: 'virtual-banker-host'
|
||||
}, '*');
|
||||
}
|
||||
```
|
||||
|
||||
Available commands:
|
||||
- `open` - Open the widget
|
||||
- `close` - Close the widget
|
||||
- `minimize` - Minimize the widget
|
||||
- `setContext` - Update context
|
||||
- `setAuthToken` - Update auth token
|
||||
|
||||
## Styling
|
||||
|
||||
The widget can be styled via CSS:
|
||||
|
||||
```css
|
||||
#virtual-banker-widget {
|
||||
position: fixed;
|
||||
bottom: 20px;
|
||||
right: 20px;
|
||||
width: 400px;
|
||||
height: 600px;
|
||||
z-index: 9999;
|
||||
border-radius: 8px;
|
||||
box-shadow: 0 4px 16px rgba(0, 0, 0, 0.2);
|
||||
}
|
||||
|
||||
#virtual-banker-widget.minimized {
|
||||
height: 60px;
|
||||
width: 200px;
|
||||
}
|
||||
```
|
||||
|
||||
## Theming
|
||||
|
||||
Theme can be configured per tenant via the backend API. The widget will automatically apply the theme from the session configuration.
|
||||
|
||||
## Accessibility
|
||||
|
||||
The widget is built with accessibility in mind:
|
||||
- Full keyboard navigation
|
||||
- Screen reader support
|
||||
- ARIA labels
|
||||
- Captions always available
|
||||
- Reduced motion support (respects OS preference)
|
||||
|
||||
## Browser Support
|
||||
|
||||
- Chrome/Edge 90+
|
||||
- Firefox 88+
|
||||
- Safari 14+
|
||||
- Mobile browsers (iOS Safari, Chrome Mobile)
|
||||
|
||||
## Security
|
||||
|
||||
- Content Security Policy (CSP) compatible
|
||||
- No direct secrets in browser
|
||||
- Ephemeral session tokens only
|
||||
- CORS configured for embedding
