Using the (magnetic) compass would require less coding, I suppose. However, is it available on all your target devices and is it accurate enough?
I should defer to someone who's actually used the compass sensor. In the meantime, you could put together a test app in just a few minutes. You could base it on the following accelerometer test code: http://stuffthathappens.com/blog/2009/03/15/android-accelerometer/ On Tue, Dec 29, 2009 at 7:11 AM, Matt <[email protected]> wrote: > Isn't it possible to use the compass magnet to track direction? > > Matt > > On Dec 29, 7:07 am, Frank Weiss <[email protected]> wrote: > > It's doubtful you can literally tell if the person has turned around.
