Somalytics’ eye-tracking sensors could make PSVR 2 tech obsolete

Somalytics says its sensors will create more natural interactions with our favorite gadgets.

What you need to know

  • Somalytics debuted the world's smallest capacitive sensors at CES.
  • These sensors are made of carbon nanotube-based paper and measure in at just 40,000,000,000th of a meter.
  • These sensors can be used for a wide variety of applications including touchless buttons, smart home switches with gesture recognition, and even camera-less eye-tracking for VR headsets.

CES is always full of unique and interesting gadgets, and one of the most interesting we've seen so far is a new type of sensor from a company called Somalytics. Somalytics is headed by a team of industry experts, including Barbara Barclay, who I sat down with virtually at CES to discuss what the startup has been working on.

In the short of it, new sensors made of carbon nanotube-based paper — which measure in at just 40,000,000,000th of a meter — are used to measure electrical impulses. Capacitive sensors are used in basically any gadget that works with taps or swipes, like your smartphone's touch screen or the touch buttons on an appliance.

Barclay outlined several use cases, including smart home sensors that can detect 3D gestures (pictured below) — and are sensitive enough to detect individual fingers for more advanced gestures — touchless buttons for public uses like elevators, and even eye-tracking in VR headsets without the need for a camera.

This last component is particularly fascinating given that Sony's PSVR 2 was just announced with eye-tracking support. That headset uses IR cameras to detect eye movement, while a headset using Somalytics sensors would detect movement via electrical impulses, resulting in a more privacy-focused outcome.

In addition to this, Somalytics sensors can detect eye movements much more quickly than a camera ever could. These sensors can run at up to 1,000Hz — compared to 60Hz for most cameras — meaning they can keep up with saccades, or the rapid, seemingly random movements of eyes. They also have a significantly lower latency than cameras provide, with less than 3ms latency versus around 30ms for a camera.

The image above shows an early prototype of eye-tracking glasses. That tech could be translated to a future VR headset without adding any real bulk or power draw the way a camera would require.

Barclay previously worked at Tobii, the company responsible for eye-tracking methods in many existing VR headsets like the HTC Vive Pro Eye and the Pico Neo 2 Eye, so it makes sense that Somalytics would be taking this approach.

Somalytics says its sensors are sensitive enough to measure several inches away from the sensor itself, which gives lends a wide variety of uses to them and could power some of the best smart home gadgets in the future.

Somalytics isn't announcing any specific partnerships with companies at this CES — citing that many of these products are still in the prototype or very early phases of consumer implementation — but it's entirely likely we'll see these in products in the near future. Thinking of future smart homes where devices are controlled without speaking to a virtual assistant or even flicking a physical switch is absolutely fascinating, and we hope to see more from Somalytics soon.

Protect your kids by setting up a supervised YouTube account

YouTube Kids has been around since 2015 and has grown into a great place for children to explore what YouTube has to offer safely. In 2021, the company is expanding ways for younger viewers to see more of what's available from the streaming service, along with a more mature interface with supervised accounts. Instead of a separate app, these accounts will use the official YouTube app, so knowing how to set up a supervised account for kids on Youtube is important. If you want to protect your child from some of the less than appropriate content that can be seen on YouTube, then you'll want to be sure to have the supervised account properly set up. YouTube announced supervised accounts as a way for kids aged 9+ to see to more of what the service offers while still under the guidelines set by their parent. So, whether you have picked up one of the best phones for kids or maybe a tablet like the Lenovo Smart Tab M10 HD that has Google's Kids Space for your child, here&#

PS5 restocks: Here are the latest PS5 stock updates & how to find one

PS5 stock is selling out fast, so be sure to have your credit card ready. Looking to buy a PS5 ? Well, so are millions of other people. It doesn't help that stock levels remain really tight, even nearly a year after its launch. Every time a retailer puts stock up for sale, it sells out super quickly. The longest we here at Android Central have seen PS5s stay in stock is between 15 to 20 minutes (often just a few minutes, though). That's also at random times, so finding a PS5 is a truly challenging task. Sony warned it will be hard to find stock throughout the year and well into 2022, but retailers promise more are coming and that Sony has secured additional semiconductor chips to make them. In our PS5 review, we called the system a technical marvel with a groundbreaking controller. And after spending a few months with the PS5, it's nearly impossible to go back to the PS4. Everything about the PS5 is better , from the games to the DualSense haptic feedback and adaptive

Samsung Galaxy S21 FE review: Better phone, worse price

This upgrade is an uphill battle for Samsung thanks to steep competition. It's hard to believe that it's been a year and a half since Samsung redefined the "flagship killer" concept with the Galaxy S20 FE . At the time, the phone blew us away with its quality, delivering a true flagship experience for a significantly lower price than a "regular" Galaxy S20. The Galaxy S21 FE was rumored to be released the entire second half of 2021, and now it's finally here. The Galaxy S21 FE debuts with some of the expected upgrades over its predecessor but still retains many of the points that made the S20 FE a more affordable device. You won't find a brand new camera array on this phone when compared to 2020's device — that's a 12MP sensor for the main and ultra-wide lenses, while an 8MP sensor still resides behind the 3X telephoto lens — but Samsung has upgraded the styling to be more in line with the Galaxy S21 and the rumored look of the Galaxy
