Google VR Cardboard is a virtual reality (VR) platform developed by Google. It allows users to experience VR content using a simple and affordable device made of cardboard. Here's how it works:
-
Cardboard headset: The Google VR Cardboard headset is a simple device made of, as the name suggests, cardboard. It typically comes in a kit with pre-cut cardboard pieces and a set of lenses.
-
Smartphone integration: The cardboard headset is designed to hold a smartphone. You need to insert your smartphone into the front of the headset, securing it with the provided straps or holders. The smartphone acts as the display and processing unit for the VR experience.
-
VR applications: You need to download and install VR applications compatible with Google Cardboard on your smartphone. These apps can be found on app stores like Google Play Store or Apple App Store. They offer various VR experiences such as games, 360-degree videos, or virtual tours.
-
Split-screen view: The VR apps for Cardboard usually present a split-screen view on the smartphone display. Each half of the screen corresponds to a separate image—one for each eye. This is known as stereoscopic rendering and creates a 3D effect when viewed through the Cardboard lenses.
-
Lenses and optics: The Cardboard headset includes a pair of lenses positioned in front of the smartphone's screen. These lenses are responsible for magnifying and focusing the split-screen images. They help create an immersive 3D effect when you look through them.
-
Head tracking: Most Cardboard-compatible apps utilize the smartphone's built-in sensors, such as the gyroscope and accelerometer, to track your head movements. As you move your head, the sensors detect the motion and update the virtual display accordingly. This allows you to look around and explore the virtual environment.
-
Interaction: Google Cardboard relies on various input methods depending on the app. Some apps may require external controllers, while others use the smartphone's touchscreen or utilize a gaze-based interaction system. For example, you can interact with certain objects or trigger actions by focusing your gaze on them.
Overall, Google VR Cardboard offers a simple and accessible way to experience virtual reality by using a basic cardboard headset, a smartphone, and compatible VR applications. It provides an affordable entry point into the world of VR and has played a significant role in popularizing the technology.
