# Tutorial: WebRTC Pointer Detector

This application shows a WebRtcEndpoint connected to itself (loopback) with a PointerDetector filter in the middle (take a look to the Media Pipeline). To run this demo follow these steps:

1. Open this page with a browser compliant with WebRTC (Chrome, Firefox).
2. Click on Start button.
3. Grant the access to the camera and microphone. After the SDP negotiation the loopback should start.
4. Click on Stop to finish the communication.
