+ * SENSOR_TYPE_WAKE_GESTURE
+ * trigger-mode: one-shot
+ * wake-up sensor: yes (set SENSOR_FLAG_WAKE_UP flag)
+ *
+ * A sensor enabling waking up the device based on a device specific motion.
+ *
+ * When this sensor triggers, the device behaves as if the power button was
+ * pressed, turning the screen on. This behavior (turning on the screen when
+ * this sensor triggers) might be deactivated by the user in the device
+ * settings. Changes in settings do not impact the behavior of the sensor:
+ * only whether the framework turns the screen on when it triggers.
+ *
+ * The actual gesture to be detected is not specified, and can be chosen by
+ * the manufacturer of the device.
+ * This sensor must be low power, as it is likely to be activated 24/7.
+ * The only allowed value to return is 1.0.
