I am working on a vehicle motion iOS app. Like user is inside the vehicle and trace the vehicle direction, braking, steering. I am very new to device sensors.

After doing some research, I am able to get Accelerometer (x,y and z) and Gyroscope (roll, pitch and yaw) data using CoreMotion framework. Also I have seen Apple Motion Graphs sample code Can anyone help me how to detect the direction and brake using this data.

I have gone through below stack overflow solutions but still getting stuck. Please help me to go further.

Anyone has any tutorial or algorithm or library to track the same? Or any way to go ahead.

Any help would be appreciated Thank you in advance!

  • instead of 'direction', try searching for 'heading': http://stackoverflow.com/questions/9341223/how-can-i-get-the-heading-of-the-device-with-cmdevicemotion-in-ios-5 – cmyr Jan 06 '15 at 17:24
