Docs for Accelerometer needs updating
-------------------------------------
Key: CB-418
URL: https://issues.apache.org/jira/browse/CB-418
Project: Apache Callback
Issue Type: Improvement
Components: Docs
Affects Versions: 1.5.0, 1.6.0
Reporter: Filip Maj
Assignee: Michael Brooks
With the introduction of Cordova-JS, the Acceleration object now returns values
in meters per second squared. So at rest with the screen facing up, all devices
should be returning: x=0, y=0, z=9.81. The docs currently report that
Acceleration values for x, y and z range from 0 to 1.
How the Acceleration method has changed over the past few versions:
* Android has always adhered to the above: reporting values as m/s^2.
* In 1.6.0rc1, iOS now adheres to the proper return values as well. Before
then, iOS x/y/z values were reported between -1 and 1.
* BlackBerry does not return values in m/s^2 and until cordova-js gets in there
it will not change. Currently the values (as documented in BlackBerry
documentation): "For example, if the handheld is lying flat on a table, the X
and Y values are equal to 0, while Z is equal to 1000"
* Windows Phone 7 returns units in m/s^2.
