19 1. Enable the Window Orientation Listener debugging data log using the
35 filtered accelerometer data, measured tilt and orientation angle, confidence
36 intervals for the proposed orientation and accelerometer latency.
42 and the latency for orientation detection goes up. One way to observe this
43 is by holding the device vertically in one orientation then sharply turning
44 it 90 degrees to a different orientation. Compared the rapid changes in the

59 different from the original orientation of the device). However, once it
61 the measured orientation angle is now within the gap between the new
62 orientation and the adjacent orientation.
64 In other words, the hysteresis gap applies only when the measured orientation
65 angle (say, 45 degrees) is between the current orientation's ideal angle
66 (say, 0 degrees) and an adjacent orientation's ideal angle (say, 90 degrees).
74 4. The orientation angle is not measured when the tilt is too close to 90 or -90
77 so there will be no orientation proposal either.
79 5. Each orientation has its own bound on allowable tilt angles. It's a good idea to
81 the device until it is inside/outside the limit for each orientation.
83 6. Orientation changes should be significantly harder when the device is held
85 a little to the side, or they hold the device loosely so its orientation
