What is ALVR - Air Light VR?
ALVR - Air Light VR is an open source software designed to wirelessly stream VR content from a PC to an Oculus Quest headset. It takes advantage of the Oculus Quest's wireless connectivity to provide a PC VR experience without being tethered to a computer via cables.
Using ALVR, Oculus Quest owners can access their SteamVR libraries and play high-end VR games their standalone headset normally couldn't handle. It streams the VR video feed over a local WiFi network, allowing for roomscale VR without any wires. The software compresses and transfers video frames from the PC to the Oculus Quest, where they are decompressed and displayed on the headset's screens.
ALVR provides tracking data using the Oculus Quest's onboard cameras and sensors. It's capable of delivering a smooth, low latency VR experience rivaling that of the Oculus Link cable. Users will need a reasonably modern gaming PC and router to use ALVR, as it requires significant bandwidth, GPU power and WiFi speed.
Overall, ALVR removes the tether of wired PC VR headsets to open up new levels of immersion. It's an impressive showcase of wireless VR technology and demonstrates the Oculus Quest's versatility as both a standalone and PC-powered VR system.
