Meta Quest 3 dropped a game-changing bomb at Meta Connect 2023: upper body tracking and AI-generated legs! Thanks to a mid-December rollout, developers can jazz up their VR apps on the Quest Store or App Lab with these futuristic features.

Dubbed "Inside-Out Body Tracking" (IOBT) by Meta, this tech marvel is exclusive to the Meta Quest 3. Imagine two side cameras teaming up with sensors and AI wizardry to snag your wrists, elbows, shoulders, and torso. It's like your VR avatar hit the gym and got a significant upgrade!

This isn't your run-of-the-mill headset upgrade – nope, it's a game-changer. Fitness apps, combat games, and the virtual social scene are in for a wild ride with more precise upper body tracking than ever before. And guess what? You won't find this awesomeness on any other standalone VR headset.

Meta Quest 3 witnessed the contrast in Upper body tracking excellence

Let's talk about the other excellent addition – Meta dubs it "Generative Legs." This nifty feature brings reality to your virtual avatar's legs.

Unlike Inside-Out Body Tracking (IOBT), Quest's Upper body tracking built-in sensors don't follow your leg's every move. Instead, an AI model kicks in, crunching numbers from the IOBT's precise tracking data to estimate where your legs should be. The twist? Generative Legs aren't picky – they play nice with the older Quest 2, Quest Pro, and new Quest 3. So, whether you're rocking the latest tech or hanging on to the classics, your virtual legs are in for an upgrade.

When you blend Inside-Out Body Tracking (IOBT) with Generative Legs, your virtual avatar becomes a mirror of your movements – all smooth and natural.

Check out the sneak peek in the video above from the upcoming Drunkn Bar Fight VR game update. On the left is the plain avatar, with no IOBT or Generative Legs magic.
