Go 3-D With Virtual Reality Headsets
By Vishakha Thakur
Virtual Reality or VR has become one of the fastest growing content segments in the world. VR headsets can allow users to consume VR content by providing them with an immersive and 3D experience. Most VR headsets that are available in the market such as Oculus Quest by Meta, use handheld controllers that function similarly to joysticks. Companies are trying their best to make the VR headsets more accessible.
What Is a Virtual Reality Headset?
A VR headset is basically a head-mounted device that includes a display screen, stereo sound, sensors, and compatible controllers to deliver an immersive and interactive audiovisual experience. Whenever a user puts on a VR headset, they cannot see the world around them. The user can only see VR content projected on the display screen such as 360-degree videos and VR games, workspaces, or meeting rooms for other activities.
The device offers an interactive experience, requiring a controller to point to objects, select, drag, and drop, scroll up or down, navigate between different VR spaces.
Basic Components of VR Headsets:
1. An array of sensors
VR headsets come with several sensors. Some headsets also have eye-tracking sensors that can understand when eyes focus on a VR object or location.
2. Lenses and screens
The lenses and screen setup makes up the bulk of the VR headset’s hardware. These are stereoscopic lenses positioned between the screen and your eyes that distort the image into appearing three-dimensional. The images in VR headsets appear to move side-to-side to recreate a 360-degree experience and is achieved by subtly moving the display content in response to head tracking data.
3. Immersive audio
A stereo audio feed comes from two directions or one for each ear. VR headsets mimic this experience using 360-degree or immersive audio technology. Binaural audio is one such technology, and the new spatial audio pioneered by companies like Apple marks another milestone in VR audio innovation.
4. Controllers
The VR headset controllers are the bridge between the real and the virtual worlds. There are a variety of controllers one can use. For instance, Samsung offers a single hand motion controller for its Gear VR kit, and Meta reportedly has developed a set of haptic-based controllers in the works that could enable pressure-sensitive touch and navigation.
