motion — Motion Sensor Data on iOS#
The motion module allows you to access your iOS device’s motion sensor data (accelerometer, gyroscope, magnetometer).
Functions in the motion module:
- motion.start_updates()#
Start monitoring the device’s motion sensors. You should balance this with a
stop_updates()call to improve battery life. All the get… functions require that you callstart_updates()first, otherwise, no meaningful data will be returned.
- motion.stop_updates()#
Stop monitoring the device’s motion sensors.
- motion.get_gravity()#
Return the gravity vector (x, y, z).
- motion.get_user_acceleration()#
Return the acceleration the user is giving to the device. The total acceleration is equal to the gravity vector returned from
get_gravity()plus the user acceleration.
- motion.get_attitude()#
Return the attitude of the device (roll, pitch, yaw).
- motion.get_magnetic_field()#
Return the magnetic field vector with respect to the device (x, y, z, accuracy).
