Device Orientation Angle (aka Tilt Angle)
To ensure that horizontal and vertical device orientation changes are detected, even when it isn‟t in the
ideal vertical orientation – where the angle θ in Figure 3 is 90°, the KXTI9 considers device orientation
angle in its algorithm.
Angle
Figure 3. Device Orientation Angle
As the angle in Figure 3 is decreased, the maximum gravitational acceleration on the X-axis or Y-axis
will also decrease. Therefore, when the angle becomes small enough, the user will not be able to make
