Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving, from an accelerometer, angle information of a device. A calibration position is measured based upon the angle information of the device when the device is at rest. A current position is constantly measured based upon the angle information of the device. A current pressure is calculated based upon the current position and the calibration position. The current pressure can be used to augment an audio signal and/or used to augment an audio instruction. |
