Bored by Skype and FaceTime? 3D video chat is on its way to a phone near you

Holostream: Real Time 3D Streaming On Your Cell Phone
Thanks to technologies like the depth sensor on an iPhone X, 3D imaging is truly mainstream. But recording holographic images and displaying them are two very different questions. In short: We have plenty of ways of easily carrying out the former, but very much of the latter. This is where researchers from Purdue University’s School of Mechanical Engineering think they can help.

They developed a new platform, named “Holostream,” which enables high-quality 3D video communication on mobile devices, using only existing standard wireless networks. Imagine a three-dimensional version of Skype, where you can rotate the image in real time, and you pretty much have the idea.

“The Holostream system includes four major modules,” Song Zhang, an associate professor at Purdue, told Digital Trends. “[There’s] a high-accuracy and high-resolution 3D video acquisition module that achieves camera pixel resolution at 30Hz; a novel 3D video compression module that substantially reduces 3D video data size; a 3D video streaming module that delivers compressed 3D video contents and decompresses the videos in real time; and 3D video visualization modules that allows the mobile device users to naturally access and interact with high-quality 3D video contents in real time at a remote location across standard networks.”

As Zhang explains, Holostream could be used for a variety of applications. For example, it’s easy to imagine it being used as a communication or messaging tool that could appeal to users once the thrill of iOS 11’s Animojis wears off. But it could also have more serious, game-changing uses — like being utilized in telemedicine or remote collaborative design.

“I am interested in making this technology commercially available,” Zhang said. To reach this point, however, the team needs to carry out more work on their 3D video compression algorithms to ensure that they are compressing low-quality 3D video data in the most effective way. Since different applications will require different levels of detail in the 3D images, this is an important part of the project.

The research carried out by Zhang’s team will be presented at the Electronic Imaging 2018 conference, running from January 28 to February 2 in Burlingame, California. Hopefully, it won’t be too long after that before we get to put it through its paces. Skype and FaceTime are seemingly boringly two-dimensional already!

How to disable 3D and Haptic Touch in iOS
An example of 3D Touch on an iPhone.

In 2015, when Apple launched the iPhone 6S, it also debuted a new iOS interface called 3D Touch. This feature uses the iPhone's pressure-sensitive surface to help you view, navigate, and control some aspects of the device's apps and features. You could use it to call up an app's Quick Actions, preview notifications, operate actions from the Control Center, and "peek and pop" with certain apps without having to launch them.

3D Touch was used in the iPhone 6S, 7, 8, X, and XS models before being replaced by Haptic Touch, which responds only to a finger press's length. While some people could use 3D Touch to their advantage and profoundly miss it, others found it unintuitive at best and annoying at worst. This article explains how to disable 3D Touch on iPhones that have it and disable Haptic Touch.

The best 3D printers under $500
3D printers are finally affordable. Here are the best models under $500
anycubic photon review 3d printer xxl 2

The 3D printing market has seen quite a few changes over the last few years. In just the span of a decade, the barrier to entry has dropped from well over several thousand dollars to under $200 in some cases. However, all entry and mid-level printers are not made equal. We have a few suggestions for prospective buyers and other information regarding alternatives not found on this list.

To some veterans of the 3D printing scene, this list may seem like it lacks a few of the most commonly recommended printers for newcomers. This is by design. Our list only considers printers with tested components from proven, reliable vendors. That's why we chose the Monoprice MP Mini v2 as our top pick--it's reliable and easy to use. We have avoided any printer with a frame primarily made from interlocking acrylic pieces and anything historically unreliable.
Most bang for your buck: Monoprice MP Mini v2
