I've been working on a project where we need to capture the smartphone displacement to capture a movement like a shoulder elevation and identify if the movement is correct or wrong. Is this possible to do?
The movement is a flood of the arm, and I need to know the displacement to say if it is correct!
Probably this is achievable. There is some scientific literature regarding this problem, which you may find useful, such as "Arm Motion Recognition and Exercise Coaching System for Remote Interaction", "What Can an Arm Holster Worn Smart Phone Do for Activity Recognition?", and "Motion recognition with smart phone embedded 3-axis accelerometer sensor"
