Field Detail

sensor

public int sensor

The sensor that generated the event. Can be any of the types listed in ISensor

values

public final float[] values

The length and contents of the array depends on which sensor was returned. The default sampling rate of the accelerometer and gyroscope is 100Hz.

ISensor.TYPE_ACCELEROMETER:

All values are in g's. 1g = 9.8m/s^2. They measure acceleration in X, Y and Z axis.

The values[] array length is 9 which stores 3 data values at the same point in time for each axis in the values[] array. Example: {x1,y1,z1} are sampled at the same point in time, {x2,y2,z2} are sampled at the same point in time, etc...

• values[0]: Acceleration on the x-axis x1
• values[1]: Acceleration on the y-axis y1
• values[2]: Acceleration on the z-axis z1
• values[3]: Acceleration on the x-axis x2
• values[4]: Acceleration on the y-axis y2
• values[5]: Acceleration on the z-axis z2
• values[6]: Acceleration on the x-axis x3
• values[7]: Acceleration on the y-axis y3
• values[8]: Acceleration on the z-axis z3

All values will be affected by gravity. One can isolate the force of gravity by applying a high pass filter.

ISensor.TYPE_GYROSCOPE:

All values are in degrees/second. They measure the angular rate in X, Y and Z axis.

ISensor.TYPE_MAGNETIC_FIELD:

All values are in micro-Tesla. They measure the magnetic field in X, Y and Z axis.
