I am wondering if any commercial Android devices fuse accelerometer, 
digital compass, and gyroscope sensor data to provide a stable and accurate 
orientation result? Preferably such sensor fusion should be implemented in 
hardware, as explained in the popular video "Sensor Fusion on Android 
Devices: A Revolution in Motion 
Processing"<http://www.youtube.com/watch?v=C7JQ7Rpwn2k>, 
where a prototype was presented based on a modified Nexus One.

This video, however, is more than 1.5 years old, which is eons in 
smartphone hardware development. Also, the citation (apparently from a 
Google/Android engineer) in this Stackoverflow 
answer<http://stackoverflow.com/a/8006832/896660>implied that new devices which 
fuse gyro data with other sensor data are in 
development (original discussion 
here<?fromgroups#%21topic/android-developers/GOm9yhTFZaM>). 
That information is also more than one year old, so could someone shed some 
light on the current situation?

Thanks,

Rob
