Gyroscope ANE Android

Question

Hi all, i've integrated the Sample gyroscope ANE from here http://www.adobe.com/devnet/air/native-extensions-for-air/extensions/gyroscope.html inside my app. Basically, this will be a retro race game ( similar to OutRun ) , with the possibilyt to drive left -> right via the gyroscope. It will run ONLY on galaxy TAb 10.1 GT-P7500.
I have some problem :
VALUES :
this is my min Value : -5.326322e-7 for each Axis ( the MAX Value SEEMS to be 5.326322e-7) .
How to convert  it to a real number ( i need to limit it from 0 to 1 left to right) ? Number.toFixed()  ?
Is there a way to normalize them in the Java part of the ANE ?
AXIS :
when i roatate the device from landscape to portrait, on which axis am i rotating ? When i try to trace it, ALL the axis change value ( and sometime they just get the MIN value of -5.326322e-7, even if the are all rotated ) .
Thanks in advance!

Answer 1

isit usefull to do it in the ANE Java ?
No. Just use Actionscript.
When im faking a steer with the device (screen i front of me, landscape) on which axis im rotating ?
use the example on the site you linked to:
var gyro:Gyroscope; if(Gyroscope.isSupported) { gyro = new Gyroscope(); gyro.setRequestedUpdateInterval(1000); gyro.addEventListener(GyroscopeEvent.UPDATE,onChange); }  
function onChange(e:GyroscopeEvent):void { trace("From gyro: " + e.x + " " + e.y + " " + " " + e.z); }
Since I don`t know details how you control your steering its pointless to guess, you must at least show how you plan to steer, control your car.
And, regardig the snippet, why  2500000 and 2663161 ? ar them -5.326322e-7 converted ?
The basic idea is to convert a solution room from (roughly -0,53 to roughly 0,53) to 0->1 (-5.326322e-7 is no space magic but simply an exponential way to write down -0.532....)
This is a linear equation with 2 unknowns which gives when solved the funtion:
f(x) = 2500000/2663161·x + 1/2

when i roatate the device from landscape to portrait, on which axis am i rotating ? When i try to trace it, ALL the axis change value ( and sometime they just get the MIN value of -5.326322e-7, even if the are all rotated ) .
use a variable that holds the orintation, and switch the formulas (of which I gave you one) depending on that
