+#### UDP Remote Control
+The Unity application listens for UDP commands on **port 5555** (configurable in Unity Inspector) for remote scene switching.
+
+**Command Format:**
+```
+SWITCH:SceneName
+```
+
+**Example Commands:**
+```bash
+# Switch to VR Task 1
+echo "SWITCH:VR-Task1" | nc -u localhost 5555
+
+# Switch to AR Task 2
+echo "SWITCH:AR-Task2" | nc -u localhost 5555
+
+# Return to Lobby
+echo "SWITCH:Lobby" | nc -u localhost 5555
+```
+
+**Python Example:**
+```python
+import socket
+
+def switch_scene(scene_name, host='localhost', port=5555):
+    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
+    message = f"SWITCH:{scene_name}"
+    sock.sendto(message.encode('utf-8'), (host, port))
+    sock.close()
+
+# Usage
+switch_scene("VR-Task1")
+```
+
+**Available Scene Names:**
+- `VR-Task1`, `VR -Task2`, `VR -Task3`, `VR -Task4`
+- `AR-Task1`, `AR-Task2`, `AR-Task3`, `AR-Task4`
+- `Lobby`
