TheAmazon Fire Phone’sDynamic Perspective — the illustrious “ 3-D effect”—works almost as if by magic . As you look at the phone and move it around , the Fire Phone watches you back , and switch what you see . It ’s not voodoo , though . It ’s half-baked television camera technical school . Here ’s a near look at how it works , even in the darkness .

At its core , Amazon ’s Dynamic Perspective is a facial - recognition and trailing engineering like to what we ’ve had on smartphone television camera and point - and - shoots for years . You ’ve seen facial expression - detect automobile - nidus — most smartphones have it — and it works decently well . You point your camera at a person , it bedevil a box around their face and focuses the picture at the correct distance so it ’s skillful and sharp .
The facial - recognition technology Amazon is using takes that same conception to a much more advanced level . It ’s not just seek to detect your face for focus ; it demand to cross the position of your face and its movements extremely accurately for a number of different U.S. .
In the showy casing , depict at the top of this post , moving your head moves the map or wallpaper or whatever in front of you to create a 3D force . Google even built an locomotive so that the outcome can be used to look around a earthly concern in game . But beyond the 3-D , the cameras watch your face so that a motion-picture show or tilt of your earphone ( or your face ) scrolls a webpage or to reveal additional info and configurations .
To do it , Amazon require perspective on you : It uses four specialized cameras that take very accurate measurement of your head ’s berth many times a indorsement . ( Jeff Bezos quote 60 times a second , but just as an deterrent example )
The cameras on the Fire Phone have a 120 level field - of - view , much wide of the mark than a received 72 degree front - facing tv camera . As Bezos explained , the wider field - of - view lets the Fire Phone track a wider mountain chain of movement , without which Dynamic Perspective would be impossible .
The Fire Phone ’s cameras supervise your head position proportional to revolve around in X , Y , izzard coordinates , as well as the angle of your head to the left-hand or the right . Depending on how much your face moves and how chop-chop you’re able to get variation or alone different effects .
In purchase order to keep caterpillar tread of your fountainhead in three dimensions , the earphone needs measurements from two cameras , much like you need two optic to comprehend three dimension . The telephone set requires four cameras amount — one in each quoin — because we all use our phones in different positions and sustain them in unlike ways count on the site or app . An algorithm limit which two are returning the best data at any given time .
to boot , since the 3D feature ask to turn even when we ’re in darker situation , each of the cameras has infrared light-emitting diode that assist the television camera see you , even in darkness .
Beyond the hardware , there ’s a database of millions of face that Amazon says took year to meet . The vast database helps the phone very accurately identify a variety of different case and fend off false positives . For deterrent example , the phone is going to regain you even if you ’re backlit or don a hat . And it wo n’t lock onto things which take care like faces but are n’t , like a three - inch image of a John Rock hotshot on a card .

The expectant Leslie Townes Hope is that we ’ve only pick up the commencement . Amazon ’s Dynamic Perspective SDK makes it easy for developers to seize and use this data . It ’s even got a few shortcut gestures . We ’ll have to hold off and see if third - parties can use Amazon tech to do what Amazon has n’t : work up some uses for the Dynamic Perspective that make us feel like we ca n’t endure without it .
