Accelerometers in Smartphones and Tablets

[bhaazee]

Today's smartphones, almost every model have accelerometers. Is it possible that one can obtain the x,y,z co-ordinate positions from these accelerometers time to time?

And how accurate are these values? Means whats the frequency of receiving signals? What is the approx. minimum displacement that once can obtain from these accelerometers?

Double integration of accelerometer data to get position is pretty inaccurate, but anything is possible given enough tolerance for error.

Thnx a lot.
