Electronic devices and methods are provided in which a pressure applied, by a driver, to a seat of a moving object driven by the driver is sensed. A state of the driver is determined based on frequency characteristics with respect to a change in the pressure sensed by the sensor. The feedback corresponding to the state of the driver may be provided. If it is determined that the driver is in a drowsy state, the speed of the moving object may be decreased or the preset audio may be output.
