  • Context recognition apparatus and method
    Patent number: 9720389
    Abstract: Context recognition methods and apparatus are provided for an application processor and a micro control unit. It is determined whether an operation switch condition for switching to a sleep mode is satisfied. A request for execution of a context recognition function is sent to a micro control unit, when the operation switch condition is satisfied. The application processor switches to the sleep mode, when the context recognition function is executed by the micro control unit. The micro control unit collects sensor data at previously stored time intervals, and previously stored state information is updated based on the sensor data.
