Measured acceleration along the X axis with estimated bias compensation. Measured acceleration along the Z axis without any bias compensation. Measured acceleration along the Y axis without any bias compensation. Measured acceleration along the X axis without any bias compensation.
SensorĪcceleration force along the x axis (including gravity).Īcceleration force along the y axis (including gravity).Īcceleration force along the z axis (including gravity). Motion sensors that are supported on the Android platform. Table 1 summarizes the motion sensors that are available on the Android platform. These data values are returned in a float array For example, during a single sensor event the accelerometer returnsĪcceleration force data for the three coordinate axes, and the gyroscope returns rate of rotationĭata for the three coordinate axes. Motion sensors by themselves are not typically used to monitorĭevice position, but they can be used with other sensors, such as the geomagnetic field sensor, toĭetermine a device's position relative to the world's frame of reference (see Position Sensors for moreĪll of the motion sensors return multi-dimensional arrays of sensor values for each SensorEvent. Or your application's frame of reference in the second case you are monitoring motion relative to In the first case, you are monitoring motion relative to the device's frame of reference Physical environment in which the device is sitting (for example, moving with you while you drive The movement is usually a reflection of direct user input (for example, a user steering aĬar in a game or a user controlling a ball in a game), but it can also be a reflection of the Motion sensors are useful for monitoring device movement, such as tilt, shake, rotation, or Depending on the device, these software-based sensors can derive theirĭata either from the accelerometer and magnetometer or from the gyroscope. Variable because they often rely on one or more hardware sensors to derive theirĭata. The availability of the software-based sensors is more Most Android-powered devices have an accelerometer, and many now include a The accelerometer and gyroscope sensors are always hardware-based. The gravity, linear acceleration, rotation vector, significant motion, stepĬounter, and step detector sensors are either hardware-based or The sensors' possible architectures vary by sensor type: The Android platform provides several sensors that let you monitor the motion
