In accordance with the LibGDX docs:
Acceleration is measured in meters per second per second.
That implies that any variations within the cellphone’s particular person sensors are dealt with at a decrease stage (in LibGDX or within the working system/driver code it interacts with) and are standardized in these models earlier than the information is handed to the code of the cellphone. sport.
So in the event you place a cellphone display on a desk, it ought to examine 9.81 on the z-axis, since that’s the push that the conventional drive of the desk applies to it to withstand the Earth’s gravity.
This must be moderately constant throughout completely different telephones and areas round Earth the place gamers would possibly wish to play your sport. Some sensors could report 9.9 or 9.7, however you will not have to cope with some units that report values ​​in $frac {dm} {s^2}$ or different unusual models that might give values ​​within the 90s or 100s.
Sensor high quality varies and a few sensors could also be noisier or have some drift. Filtering a number of samples taken over a time window will in all probability be sufficient to get usable tilt controls on most units.
When accessible, think about using the accelerometer along side a velocity gyroscope or magnetometer. Sensor fusion (combining readings from a number of defective sensors into one artificial studying) can provide you a way more steady and correct image of how your cellphone is oriented or shifting.
