Reference point for MPU 9250 movement sensor

Other Parts Discussed in Thread: CC2650

Hi,

I am using MPU9250 InvenseSesne (CC2650 SensorTag) to detect hand gestures. I can sense the output data of accelerometer on console.

But could anyone please tell me how to get the directions. when i make the same gesture (like hi, bye) facing different directions then the sensor output data is behaving differently,

So, please tell me how to set a reference direction or axis so that even if i stand facing different directions, I should get same values which can be used to recognize the gesture. Also, it would be great if someone can tell me how to fix x,y,z axis relative to the direction of the person.

Would really appreciate an early response.

Thanks and Regards

    Hello,

    In addition to searching the forum for MPU9250 related implementations, I suggest following up in the Invensense developer forum for questions specific to the MPU9250 motion sensor.

    Please do let us know when you have it working as this does look interesting!

    Best wishes
