find out if an android device has physically moved, not it's location or speed
<p>I spent the last 12 hours investigating the possibilities of doing indoor, small distance navigation based on accelerometer and compass readings. Things aren't looking good, measurement quality is terrible and unreliable.</p>

<p>I was wondering if there is any other method of finding out whether the player (its for a game, or some interactive experience platform) has moved his location a significant amount (> 1m).</p>

<p>I don't need accurate readings (although that would be great), just knowing whether the player is moving or standing still would be a great help. I wouldn't even know where to begin to look for this, and I haven't been able to come up with any brilliant ideas myself.</p>
