This is a staging area for visualizing sensor data on iOS devices by doing a bit of 3D coolness with CSS3.

Planned:

m/s²

These are the raw output obtained from Javascript event APIs.

Incident force (i.e. acceleration) measured in the device reference frame:
fgx =

fgz =
The following are (no sensor found) Tait-Bryan intrinsic Z-X'-Y" angles. On iOS (as of 6.1), alpha is a relative heading, which will accumulate drift error, while beta and gamma are auto-normalized based on gravity direction, and are therefore absolute readings.
α =
β =
γ =
The compass heading is also an absolute reading; arrow points North.
