Vivo’s new face ID tech has 10 times as many sensor points as the iPhone X

By

Vivo, the Chinese phone maker that’s been on the leading edge of bezel-less phones this year, has today announced another major new piece of technology: a 3D depth-sensing system with 300,000 sensor points, 10 times the number in Apple’s Face ID on the iPhone X. Vivo’s new tech, mounted on the front of the phone next to the selfie cameras, works by sending out a pulse of light and calculating the “time of flight” (TOF) that the light takes to bounce back to its sensor.

The broad term for this type of technology is “structured light,” and it’s something other companies like Oppo have also considered for their phones this year, but none have yet decided it’s worth the added investment and complexity to include it in their phones. Vivo’s demonstration of its TOF 3D sensor at MWC Shanghai this week indicates that it will be among the first Android vendors to step up and compete with Apple’s Face ID directly.

“By combining TOF 3D Sensing Technology with AI, we will continue to explore new possibilities for a better future,” said Alex Feng, a senior executive at Vivo. One of the ideas envisioned by Vivo is to take in a full body scan of a person and then feed that information to a beautification AI that would more intelligently and proportionately pretty you up. Another is to use the same full-body scans to try on clothes virtually.

Beside the obvious applications of more precise biometric authentication and better portrait mode for selfies, Vivo’s new sensor could also be used for gesture and motion recognition. With a claimed depth detection as far as 3 meters, this system could also enable new augmented reality applications or the scanning of furniture and other objects.

The press release for Vivo’s TOF 3D sensor promises that “this is no mere proof of concept,” though the company hasn’t given an exact timeline on when the technology will be commercialized in an actual phone.

The PlayStation Classic has a secret debug menu that can be reached with specific keyboards

By
Just a day after the release of the PlayStation Classic , the Retro Gaming Arts YouTube channel has discovered that you can access the emulator’s settings menu by plugging a keyboard into a free USB slot and hitting the Esc key. Doing so reveals a host of settings for the built-in open-source PCSX ReARMed emulator, potentially allowing access to options, including save states, controls, and cheats. The discovery has raised hope that some of the criticisms of the retro console , such as a limited game library and poor image quality, could soon be addressed with third-party modding. In the discovered menus, an option to “Load CD Image” is clearly visible, which suggests it might be possible to load additional games or perhaps just the better-performing 60Hz NTSC variants. An option to enable scanlines, the horizontal lines that allow an LCD screen to emulate the look of a traditional CRT monitor, is also present. Despite the discovery, it’s unlikely that the hardware limitations o

With Toys R Us gone, Amazon wants to send out a holiday toy catalog of its own

By
Now that Amazon has helped kill off Toys R Us , it wants to borrow the retailer’s iconic print holiday toy catalog . The online behemoth is interested in creating its own print catalog to mail out and also be handed out at Whole Foods (which it owns), according to Bloomberg . Toys R Us was plagued with billions in debt when permanently closed last month — in part because of competition from online stores like Amazon . For many kids, its “Big Book” toy catalog was a staple of fall. The 100-page catalog would arrive near the end of October for kids to look through and create a wishlist before December. Now that the retailer is done, various companies are trying to scoop up the customers that headed to their shelves every December. Party City, for example, will open 50 pop-up toy shops for the holidays. Target will have more store space for toys . It’s just especially amusing that Amazon, having helped kill off these physical retailers, is trying to learn from them to make even mor

Amazon’s plans for a New York office are under new scrutiny

By
A month ago, when Amazon announced that it would build regional offices in New York and Virginia at great expense to the taxpayers there, I wrote that it had misunderstood the moment : Perhaps the furor over Amazon’s regional offices will blow over. But it’s hard not to feel today as if the company misread the room — overestimating the public’s appetite for a billion-dollar giveaway to one of the world’s biggest companies, and underestimating the public’s ability to raise hell on- and offline. Amazon may yet feel that pain, in the long run. Today, Amazon met the room: 150 protesters who showed up to the first New York City Council hearing about the plan. According to reports from the scene, demonstrators’ concerns start with the $3 billion in incentives that New York plans to give Amazon in exchange for locating there — and, it says, creating 25,000 jobs. Here’s Leticia Miranda in BuzzFeed : ”You’re worth a trillion dollars,” New York City Council Speaker Corey Johnson told the
