Hello
I am trying to add the option of offsetting gauge view ("offset").
i.e: If I tilt the phone around the X axis by angle theta, I want this position to be considered as like there is no tilt at all- defined as the "offset" point (angle around X axis is zero, and also angle zero aroung Y and Z axes), and all the following rotations around the x, y, z axes will be in relative to my "offset" point.
I have struggled with that for a while, so I will appreciate if you will be able to help me.
Thanks.

Hello sir, I want ask.. why I opened in simulator, the system can work but when I opened it in virtual device, the system crash when I click the button start log. Can you help me sir? Please.... Thankyou

Would you be open to making this an app that makes your phone into a ruler?

The app would know what size dimensions the phone is, and calculate the rotations the phone makes.

It might be a little off, but it would do very good for sizing in clothes. For example, the neck size is generally allows for about 1/2 inch off.

I've been trying sensor-fusion for the past couple of days -- I made a very simple implementation based on Paul Lawitski's complimentary filter. All works great when the device is flat.

As soon as I bring the device upright, roll values go for a toss; the problem is the call to calculateAccMagOrientation() which internally calls getRotationMatrix() and getOrientation(). The rotation matrix returned is in the NEG axes (North, East, Ground). These align when the device is flat, but change when device is made upright. This results in bizarre roll and yaw values. A quick fix is to use SensorManager.remapCoordinateSystem(), but this is outright hacky.

Paul L.'s code suffers the same problem. All's great when flat, but the roll&yaw values mess up when device is straight. I haven't been able to explore your code entirely, but does your app not suffer the same issue as it is based off of Paul L.'s code?

Hello
Is this api a gyro compass, meaning identity quaternion is orientated at north?

Now I have a requirement，
The gyroscope horizontally on the desktop automatically calibrates，after the transfer of data to calibrate my application?

Hi all,

Thanks for your good example.
But when I launch this application on two different devices, the axis are inverted...

1. Samsung galaxy tab s2 (SM-T810): works like a charm
2. Samsung Galaxy Tab Pro 10.1 LTE (SM-T525)

Any idea?

I use the GyroscopeOrientation to filter sensor for VR rotation,most time it works perfect well.but sometimes（eg.when device is quick move or rotation，or not move at all）,the values of getOrientation() is in disorder,this result my VR content rotate strangely. I tested this project's apk,it have the same trouble,if i move quickly the x angle range is very big. My math is terrible,could you give me some advices how to fix it or avoid it ? Thank you sir ,it 's so clever of you to do so hard algorithm.
