Answer: (c).By emitting an ultrasonic pulse from a special pen which is detected by two or more microphones. Explanation:One type of digitizing tablet, the sonic tablet, can potentially be adapted to provide 3D input. It does this by emitting an ultrasonic pulse from a special pen. This pulse is then detected by two or more microphones, which use the time it takes for the pulse to reach them to triangulate the pen's position in three dimensions. This can provide a way to input 3D information directly into the computer.
