Magic 3D Cameras. How do they work?

A dual lens camera, like that on the back of an iPhone X, uses the lens separation to detect a parallax shift to measure 3D depth? Objects closer to the camera, shift by a greater distance between the two lenses. This parallax shift, based on distance, is called disparity. 

Then how does the single lens front-facing camera measure depth? This technology is called TrueDepth. You might be surprised to know that the TrueDepth camera projects an infrared light pattern in front of the camera. By observing how the pattern is distorted by objects in front of the camera lens, the snapshot software calculates the distance from the camera to each point in the image. From this, it creates its own disparity. 

Both technologies then generate a secondary image of depth pixels. But instead of each pixel representing a color, the pixels represent depth at that point. By combining a depth map with colors it is possible to blur or even make transparent parts of a photo such as the background of a portrait.

Quantum Entanglement = Simulated Reality

Do not read this article if you are timid and want to believe this world is real. It's like taking the red pill. The article was written by one of our contributors, Rob Adamson.

The transcript about Quantum Entanglement and Simulated Reality was published on Medium by Hacker Noon and featured on their home page.

There seems to be quantum proof that we are all living in a computer simulation.

Generate an Android App from your YouTube Videos Channel

There's an Android App (APK) builder called AppGeyser that has an option for turning your YouTube videos channel into an Android APK. This seems like a great way to get more subscribers.

Just click this AppGeyser link and select Start Now. Then in the template search box, enter "you" and select YouTube, like so:

You will be asked to enter the URL of your Youtube Channel and then it will generate an APK. They also make it easy to publish your App to Google Play. 

However, even if you don't have an Android device you can fully test your App with a technology called BlueStacks. For example, here's a download for a Mac version of BlueStacks. Test your generated Android Apps in BlueStacks on a Mac or PC and then publish it to Google Play. 

Here's BlueStacks in action. It lets you run your own local APK Apps or grab any Apps from the play store for use on your desktop.

Augmented Reality is used to make learning fun and memorable. MondlyAR actually engages you in spoken conversations.

The Speech Recognition technology is almost like having your own private tutor. This is their best feature in my opinion. 

You will need to buy Subscriptions depending on how many languages you want to learn and for how long. There's also a lifetime subscription deal here on StackSocial where you can save $1,000 bucks. Bucks in French is des dollars.

Mondly won the App Store's Best of 2016 award and landed Google Play Editor's Choice App. 

There is a YouTube Mondly Chanel here. 

Best Camera Recommends Mondly mostly because of the Speech Recognition technology. The Augmented Reality needs improving, but AR in general is getting better for all Apps.
