It is the same as asking how a drone keeps track of the g vector as it flies around and and does stunts like flipping or banking. The small drones use the same 3 axis accelerators and gyros (often in a single chip) as phones. Answers are more likely to be found by searching for drone control algorithms and inertial navigation and the math behind them. Try a search on "the math of drone control". It produces some promising pages. | |

| Dec 15, 2021 at 15:24 | comment | added | Mike | @MasA Your question starts with "In their formulation, I see that one is angular and the other one is linear." We have no idea who "their" refers to, or what "one" and "the other one" might be. Please clarify what you're talking about. We can't answer without understanding what you're asking. | |
| Dec 15, 2021 at 15:17 | comment | added | Mas A | @DKNguyen, Suppose that I am walking and I hand my phone to my friend who is walking next to me. I am interested in how I hand the phone. I want to work on the pattern of this. For example: Let's say I'm looking for the answer to the question of whether each person has a unique phone handing pattern. Let the sensor be a sensor integrated into the smartphone. | |
