b. Accessing USB Camera:

You can use the UVCCamera library. Here's a basic way to integrate it:

1. Clone the UVCCamera repository.
2. Import the library into your Unity project.
3. Create a bridge class in Unity to interface with the library.

3. Display Camera Feed in VR:

a. Create a 3D Plane in Unity:

• In the Unity hierarchy, right-click and create a 3D Plane.
• This will be used to display the camera feed.

public RawImage displayImage; // Drag your RawImage component here in the inspector

void UpdateCameraFeed(Texture cameraTexture)
{
    displayImage.texture = cameraTexture;
}

• Use Oculus Integration's OVRInputModule to make the UI interactive in VR.

b. VR Controls:

• Use the OVRInput class from Oculus Integration to detect button presses and controller movements.

5. Testing:

• Build and run your Unity project for the Android platform.
• Wear your Quest 2 and test the app's functionality.

6. Deployment:

• Follow Oculus' submission guidelines to submit your app to the Oculus Store.

7. Considerations:

• Regularly test with different USB OTG cameras to ensure broad compatibility.
