Hi guys,
I am trying to learn and understand how the alpha, beta and gamma in touch orientation work. I did a test where three text objects display the values for each at every tick. I rotate my phone in every type of axis to test it out and get a better understanding of how it works. Problem is I really don't understand the results.
For example: When I hold it standing up straight on a table, the gamma which I read is in charge of right to left tilt, was somewhere in 80s. I thought that it was reading it close to 90 degrees. But when I tilt it roughly 30 degrees to either side, the numbers jumped a lot. It even went until the 10s. Another thing, I just tilt my phone to the left or right, but all three values changed a lot. I tried various axis movement and all three values moved around a lot. And also sometimes the numbers jump from negative to positive. For example, holding it in my slightly shaking hands, the value could jump from +80s to -80s. That was really confusing to me.
I apologize if I am missing something obvious here, but I really do hope that someone would be able to shed some light on this. For your reference, I tested it out on my HTC One using Crosswalk in the Intel XDK debugger test. Would really appreciate any info and guidance on this. Thanks.
