gyroscope
g
yroscope
sensor
determines rotational
velocity of the device in each axis
.
use values
obtained from the gyroscope sensor to determine the orientation of the device in
space
if
you are interested in determining the attitude (yaw, pitch, and roll) of the device,
use

apis
Senses→has gyroscope
Indicates
if the gyroscope is available on the device
Senses→has
motion
Indicates
if the motion can be computed on the device. Motion requires accelerometer, compass and gyroscope.
Motion→
gravity
Gets
the gravity vector associated with this reading.
Motion
→
acceleration
Gets
the linear acceleration of the device, in gravitational units.
Motion→
yaw
Gets
the yaw of the attitude in degrees
Motion→
pitch
Gets
the pitch of the attitude in degrees
Motion→
roll
Gets
the roll of the attitude in degrees
Motion
→rotation
speed
Gets
the device rotation speed in degrees per sec.
Motion→
time
Gets
a timestamp indicating the time at which the reading was calculated
