+ * in the calculation as the magnitude approaches 0. By performing the low-pass
+ * filtering early, we can eliminate most spurious high-frequency impulses due to noise.
+ *
+ * - Convert the acceleromter vector from cartesian to spherical coordinates.
+ * Since we're dealing with rotation of the device, this is the sensible coordinate
+ * system to work in. The zenith direction is the Z-axis, the direction the screen
+ * is facing. The radial distance is referred to as the magnitude below.
+ * The elevation angle is referred to as the "tilt" below.
+ * The azimuth angle is referred to as the "orientation" below (and the azimuth axis is
+ * the Y-axis).
+ * See http://en.wikipedia.org/wiki/Spherical_coordinate_system for reference.
+ *
+ * - If the tilt angle is too close to horizontal (near 90 or -90 degrees), do nothing.
+ * The orientation angle is not meaningful when the device is nearly horizontal.
+ * The tilt angle thresholds are set differently for each orientation and different
+ * limits are applied when the device is facing down as opposed to when it is facing
+ * forward or facing up.
+ *
+ * - When the orientation angle reaches a certain threshold, consider transitioning
+ * to the corresponding orientation. These thresholds have some hysteresis built-in
+ * to avoid oscillations between adjacent orientations.
+ *
+ * - Wait for the device to settle for a little bit. Once that happens, issue the
+ * new orientation proposal.
