A cozy band wrapped snugly around my wrist was easily the most fascinating reveal at Meta Connect. Called the Neural Band and bundled with the new Meta Ray-Ban Display glasses, it adds gestures and motion sensing that makes the experience feel thoroughly futuristic -- and full of unanswered questions. I chatted with Meta's CTO Andrew Bosworth for some answers. Wearing the Display glasses himself, he discussed the special waveguides that make the lenses transparent, the potential of the neural band's electrodes and why higher-index prescription lenses for people like me still aren't available. Watch this: We Talk The Future Of Meta's Ray-Ban Display and Neural Band With Meta 18:54 Neural band as TV remote, keyboard or adaptive accessory Bosworth says the electromyography-based neural band tech could adapt to individual behaviors and potentially serve a wide range of accessibility functions. For now, the band only works with the Ray-Ban Display glasses, but Meta envisions it as a potential interface for other products, too. One potential use is as a TV remote. "Once you start using it regularly, you put it on your wrist and you just start using it every day, it becomes infuriating that you're not using it for more things like picking up a TV remote," Bosworth says. "We think the opportunity for this to be a bigger input platform over time is really big." We also talked about the possibilities for typing, something Meta's research groups have discussed in the past. Bosworth says two neural bands would be needed, but it's being explored. "A really fun thing happens when you have two of these, you could also do typing. That's not a guarantee. We can do typing with downward-facing cameras pretty effectively, but [they're] expensive," he adds. Talking with Meta's Andrew Bosworth on Meta's campus, where I also got a little look at a transparent neural band design. Meta I asked about accessibility as well: Could the band be used to help someone with a lower range of motor skills, or no hand at all? The answer? Not yet, but adaptive functions are planned for the band's next phase. "This is trained primarily on a model of people for whom they're sending motor signals down at a high fidelity to the appendage that they're moving," says Bosworth. "I don't think we've done any of the work yet to understand how it would affect somebody who either had a limb and lost it, or never had one." But he sees potential. "There's no fundamental limit here. I think we can do a lot with this technology, and we're enthusiastic about that." Meta's Neural Band has electrodes on the inside, and fits snugly on-wrist. Meta Will the glasses or band also work as fitness trackers? We talked about fitness on glasses, something Meta's dipping its toe into with the upcoming Oakley Meta Vanguard visor that pairs with Garmin watches. The Meta Ray-Ban Displays won't work with fitness apps yet, but that could change. And could the neural band eventually serve as a fitness tracker, or even a watch band for devices like Garmin watches? Possibly. "We are looking at a huge spectrum of options," says Bosworth. "We already have plans to miniaturize all these pieces [on the band], to increase the signal that we're able to get from the wrist, and to put more sensing -- either here or in conjunction with other things like a watch or a display." Will the glasses ever work with more AI models and partners? I'd love to see Meta's glasses work with AI beyond its own, such as ChatGPT or Google's Gemini. While Bosworth didn't commit to anything specific, he did express interest in greater flexibility for apps and even AI models. "As happens so often, with Gen 1, you often have to do it yourself," Bosworth says of the Meta-made apps on the Display glasses and their exclusive focus on Meta AI. "Obviously, we hope this becomes a platform that supports a huge range of consumer applications." I test drove the Meta Ray-Ban Display glasses and the neural band, but my vision isn't compatible with them. I needed extra inserts (shown here, though they aren't representative of how supported prescriptions will eventually look). Scott Stein/CNET Maybe my prescription will be possible, someday I require a pretty strong prescription and wear higher-index curved lenses that don't work with Display glasses -- yet. Bosworth explained that the culprit is the Ray-Ban Display glasses' current flat lenses. Meta is working on possible solutions, but it sounds like the design will need some changes to make it viable. I wonder if Meta might eventually consider magnetic lens inserts, like Rokid is planning for its upcoming smart glasses, or as current VR headsets use. During my Display demo, I tried an insert that worked fine, though it did make the lenses thicker. I'd gladly live with that if it meant I could actually use them.
