Abstract: Operation of a device may be influenced based on whether the device is being tilted or has been picked up. Accelerometers gather accelerometer data that is processed to determine a reference pose. The reference pose is determined by analyzing the accelerometer data to determine “quiet” periods of accelerometer data. A moving average of the quiet periods is used to determine the reference pose. One or more override techniques may be used to compensate for noise in the accelerometer data, such as produced by the device playing music. The accelerometer data may be processed to compensate for other influences, such as intended movement of the device by one or more actuators. This processed data is compared to the reference pose. Responsive to the processed data exceeding a threshold value, the device may stop moving the one or more actuators, present output on a user interface, and so forth.
