A method uses a computing device that includes a first processor in a first, inactive state operatively coupled to a second processor in an active state. While the first processor is in the first state (301) the second processor uses sensors to determine (303) that a first condition occurred. In response to determining that the first condition has occurred, the first processor initializes (305) to a second, active state. If the first or second processor determines (311) that a second condition has occurred within a given time period (307 and 309) after the first condition occurred, the first processor performs (315) a first action such as launching a software application, capturing a digital photograph, or placing a phone call.
