Why is it so hard to build a metaverse avatar — a visual representation of ourselves in the digital world — that walks on two legs?
"I think everyone has been waiting for this," said a cartoonish digital version of Meta CEO Mark Zuckerberg, unveiling his new avatar legs and jumping up and down at a virtual-reality event Tuesday. "But seriously, legs are hard. Which is why other virtual reality systems don't have them either."
Early avatar models introduced by Meta, as well as Microsoft, have been ridiculed for appearing as legless, waist-up bodies floating around their virtual worlds.
That's in part because tech companies have been eager to show off their progress in building out virtual-reality environments while still working on the technical challenges of making avatars more human-like and realistic. Meta renamed itself from Facebook last year in hopes of jumpstarting its corporate transformation into a provider of metaverse experiences for work and play.
Zuckerberg described legs as "probably the most requested feature on our roadmap" and said they will be available soon on Meta's Horizon virtual-reality platform. He said the challenge is perceptual, involving how the brain — taking in images seen though a virtual-reality headset — accepts a rendering based on how accurately it is positioned.
Legs are harder to render accurately because they're often hidden from view.
"If your legs are under a desk or if your arms block your view of them, then your headset can't see them directly," he said.
Zuckerberg said the company has been working to improve how its artificial intelligence systems track and predict where legs and other body parts should be moving.
Review: Director-Writer Megan Park’s “My Old Ass”
They say tripping on psychedelic mushrooms triggers hallucinations, anxiety, paranoia and nervousness. In the case of Elliott, an 18-year-old restless Canadian, they prompt a visitor.
"Dude, I'm you," says the guest, as she nonchalantly burns a 'smores on a campfire next to a very high and stunned Elliott. "Well, I'm a 39-year-old you. What's up?"
What's up, indeed: Director-writer Megan Park has crafted a wistful coming-of-age tale using this comedic device for "My Old Ass" and the results are uneven even though she nails the landing.
After the older Elliott proves who she is — they share a particular scar, childhood memories and a smaller left boob — the time-travel advice begins: Be nice to your brothers and mom, and stay away from a guy named Chad.
"Can we hug?" asks the older Elliott. They do. "This is so weird," says the younger Elliott, who then makes things even weirder when she asks for a kiss — to know what it's like kissing yourself. The older Elliott soon puts her number into the younger's phone under the name "My Old Ass." Then they keep in touch, long after the effects of the 'shrooms have gone.
Part of the movie's problem that can't be ignored is that the two Elliotts look nothing alike. Maisy Stella plays the coltish young version and a wry Aubrey Plaza the older. Both turn in fine performances but the visuals are slowly grating.
The arrival of the older Elliott coincides with her younger self counting down the days until she can flee from her small town of 300 in the Muskoka Lakes region to college in Toronto, where "my life is about to start." She's sick of life on a cranberry farm.
Park's scenes and dialogue are unrushed and honest as Elliott takes her older self's advice and tries to repair... Read More
