Full body tracking makes your VR experience a lot more immersive, bridging your body movements perfectly to virtual space. So far Quest 2 only has trackers on the head and hands. But with the help of AI, Meta has developed the ability to estimate body poses with QuestSim. Body tracking tracks users' body movements through sensors. Full body tracking makes your interactions in virtual reality more realistic using more accurate models of human bodies.

Every day, nearly 2.5 billion people log in to one of the Facebook family of services, which include Messenger, Instagram, and WhatsApp. And as users scroll, message, like, and click, Facebook continues to scoop up data, which they package up for advertisers. Behind the scenes, artificial intelligence allows Facebook to make sense of all the messy data it collects about our likes, dislikes, aspirations, and relationships. Facebook's billions of users and vast vault of data make it the perfect sandbox for the company's developers and engineers to experiment, solve problems, and push the boundaries of what AI can do. Here are a few of the ways Facebook is using artificial intelligence to evolve and continue to meet the needs of its ever-expanding user base.

It explains how they are used in computer vision and NLP and the fundamental differences between the two types of artificial neural networks.

Researchers and engineers from Facebook Reality Labs and Oculus have developed what is, as of today, the only fully articulated hand-tracking system for VR that relies entirely on monochrome cameras. The system does not use active depth-sensing technology or any additional equipment (such as instrumented gloves). We will deploy this technology as a software update for Oculus Quest, the cable-free, stand-alone VR headset that is now available to consumers. By using Quest's four cameras in conjunction with new techniques in deep learning and model-based tracking, we achieve a larger interaction volume for hand-tracking than depth-based solutions do, and we do it at a fraction of the size, weight, power, and cost. Processing is done entirely on-device, and the system is optimized to support gestures for interaction, such as pointing and pinch to select.

CHIBA – At this year's Tokyo Game Show, the big draw was next-generation 5G networking -- setting pulses racing with the prospect of a radically more immersive gaming experience. Offering data transmission speeds around 100 times faster than 4G, 5G is expected to enable more seamless imagery -- particularly lower latency, more vivid images -- and sharper motion. Industry experts say it will dramatically improve the quality of augmented and virtual reality games. "It was very smooth, responsive and consistent," said Omar Alshiji, a 23-year-old game designer from Bahrain, after trying out the fighting game Tekken at the NTT Docomo Inc. booth. The major mobile carrier installed 5G base stations at its booth this year, making the high-speed network available at the show. The four-day industry event, held in the city of Chiba, ended Sunday.
