Filip Maj commented on CB-152:
------------------------------
Hey Markus, not sure what the default return values are for acceleration coming
from the webOS services, but essentially we want the values returned to be the
force (in meters per second squared) acting upon the device. iOS and WP7, for
example, returned values in the range of -1 to +1, so we multiplied by -9.81 to
get the proper m/s^2 values.
Hope that makes sense.
> Normalize Acceleration object x,y,z to return same range for all devices.

> Key: CB-152
> URL: https://issues.apache.org/jira/browse/CB-152
> Project: Apache Cordova
> Issue Type: Sub-task
> Components: webOS
> Affects Versions: 1.5.0
> Reporter: Bryce Curtis
> Assignee: Markus Leutwyler
>
> Acceleration object should be consistent across platforms. Documentation
> mentions range of x,y,z to be 0-1, but Android returns ranges in -10 to +10.
> This needs to be made consistent so the same code works on all platforms.
> Let's work towards using the DeviceMotion specification: returning values in
> m/s^2. At rest, with the screen pointing upwards, values should be x=0, y=0,
> z=9.81
> Android and iOS are using values returned as m/s^2.
