Amongst the Modern Fire Phone ’s most rumor and anticipated features is a “ 3d effect , ” which Amazon calls “ Dynamic Perspective . ” It changes follows your face as you tilt the phone in different room , altering the image in front of you . The potentiality is pretty exciting .
What does it do ?
Before explaining how the actual technology works , Jeff Bezos sagely give us a telephone number if examples of what it actually does . Dynamic Perspective can be used for a host of one - handed gesture so that you’re able to scroll through a web page or page through a book without ever tapping your earphone .
In one causa , Bezos showed how by simply tip the sound you could scroll through a luggage carrousel of images . A luminance tilt moves the carousel slow ; a unvoiced tilt gives you more of a flipbook effect . The speed of the motion is applicable to scrolling as well .
Perhaps the most striking example of the technology in action was in maps , where a 3-D overhead view of the Empire State edifice moved around as the phone moved around . Meanwhile flicks added and removed layers of data .
Overall , the implementations seemed knavish when used by a seasoned hustler , but on the other script they could become very puzzling to the chance user .
How does it work ?
The key as Jeff Bezos explains , is n’t so much using the built - in gyroscope or accelerometer , but instead keeping track of where your facial expression is at all time with photographic camera .
In addition to the front - facing television camera , which only has a 72 - stage field of view , Amazon developed newfangled spacious angle television camera with 120 - degree playing field of horizon . The telephone needs to practice more than one tv camera to know both X , Y , and , ezed directions . At any given time , the Fire Phone is only using two of the four cameras . And for situations when it ’s two wickedness for the visible sluttish camera to exploit , each of the photographic camera have a establish - in infrared light-emitting diode . grant to Amazon the camera are “ extremist - low power ” and use their on consecrate processor .
As with the Firefly visual recognition applied science , Amazon ’s Dynamic Perspective SDK will be uncommitted to third political party developers so that they can work up out their own applications for the technology .
In short , Amazon has produce some incredible tech , but it ’ll be up to the strength of the software package that ’s recrudesce using Dynamic Perspective to pair the potency . It ’s definitely impressive — whether it ’s a worthwhile experience is another interrogation tout ensemble .
