Detecting and processing button press events for performing electronic device operations

摘要

This is directed to processing inputs received from an input mechanism to control media playback operations and volume. The input mechanism can include a first button providing inputs by shorting an electrical circuit, and a second button providing inputs by changing the resistance or tone detected or received by a processor. To process inputs, a processor can first detect and process short events from the first button, and subsequently process button events from the second button.
