When the Portrait/Landscape Switching application receives this message, it clears its state, and it starts to receive new messages updating the tilt angles. Thus our cross-talk mechanism allows the system to shield the Portrait/Landscape Switching application from mistakenly interpreting manipulative tilting of the display resulting from TiltScroll. Our mechanism provides a foundation that can help developers author responsible applications that effectively share the sensor data without interfering with other (possibly unknown) uses for the same sensors.

Finally, the user must tilt the device within a range typical for holding a telephone handset; that is, we sense the natural posture that the hand makes when holding the device to one’s ear. If these conditions hold true for a short timeout, the device makes a distinct click (to give early feedback that the gesture has been recognized), and then starts the device’s voice recording software. This software issues a single sharp beep just before it starts recording, after which the user can leave a voice memo.
