It graphs their values and responds to changes in orientation, so you can compare it to your results. Also you will want to make sure you are "calibrating" your sensors (the figure 8 motion thing) on all 3 axes especially if your device is sitting next to your computer or other sources of interference. This will always make it look wrong. Not to doubt Carlos but if the "OG" ACCELEROMETER sensor was not present on XOOMs I feel many, many apps would break on it. Try ORIENTATION vs MAG + ACCEL approaches for your purposes - move the phone in a sphere, or from in front of you to over your head - take a look at the values and behavior. Both will respond to this differently, and will "break" in different places. Whichever works for you best is the one to pick is my 2 cents on it. Both methods are doing a "sensor fusion" of the MAG + ACCEL hardware sensors, just using different math for different results for the yaw/pitch/roll values. If neither works the way you want, for example you want skymap style 360 degree spherical stuff, you have to seek other methods + math etc. -- Adam Ratana adam.rat...@gmail.com -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
