摘要
Examples of devices, systems, and methods for estimating a portable computing device's acceleration when vibrating by using its internal microphone are disclosed. In one example, a portable computing device (100) has a haptic output device (118) that outputs a haptic effect causing the portable computing device (100) to vibrate. An audio signal from a microphone (142) in the portable computing device (100) is captured while the portable computing device (100) vibrates because of the haptic effect being output. The audio signal can be used to estimate the acceleration of the portable computing device (100) caused by the output of the haptic effect.
