Imagine, you have different OCR tools to read text from images but none of them gives you a 100% accurate output. Combined however, the result could come very close to the ground truth - What...

There appear to be many old examples of getting the current cardinal direction on Android devices, but an official solution provided by Google does not appear to be in their documentation. The old...

I'm using sensor data of type ROTATION_VECTOR in my app. Using my Nexus 5 I can get azimuth from orientation[0] and can get the phones heading in the range shown in the picture below (it's very ac...

Currently I am implementing a head tracking solution that takes yaw and pitch from 2 difference sources; a gyro and a magnetic field sensor. I have both the values passed into my program and now I...

My question may seem trivial, but the more I read about it - the more confused I get... I have started a little project where I want to roughly track the movements of a rotating object. (A basketba...

I have raw data of Gyroscope and magnetometer. on basis of this data, i have to calculate Heading information with an accuracy of 1Deg. I would like to know, is there any algorithm which can help ...

I'm trying out Sensor.TYPE_ROTATION_VECTOR on Android. It is supposed to use magnetfieldsensor, accelerometer and gyroscope to provide accurate rotation at all times. However, I notice enormous dri...

I've made a robot controlled by Arduino and Processing, that moves in a room by rotating itself (like a sphere). What I need is to be able to get the new location once it moves on the floor ...

I'm learning the Basics of Android programming. I have a simple android test application in which i log the accelerometer,magnetometer and the orientation data to an external file while also displ...

Instead of doing my own sensor fusion, I am using the Quaternions available from iOS and converting them to Euler angles. I walked around in a rectangle shape for few times and I observe that the...

I have been working on Orientation estimation and I need to estimate correct heading when I am walking in straight line. After facing some roadblocks, I started from basics again. I have implement...

I am trying to estimate heading from the accelerometer, gyro and magnetometer data. I have implemented A Complementary Filter from here. What I am trying is that I am holding the phone in my hand...

I am trying to get device tilt (device rotation along y-axis but unfortunately i am unable to achieve my goal. I have tried a lot of stuff using TYPE_ACCELEROMETER and TYPE_MAGNETIC_FIELD as a comb...

We are thinking about detecting the hand, user is holding his mobile device, right or left hand or both. As far as our knowledge we think this is not possible with 100% accuracy with the curr...
