1. A method for controlling an electronic device including an accelerometer, a proximity sensor, and circuitry, the method comprising: detecting with the proximity sensor whether the electronic device is physically enclosed in a small space; detecting whether the electronic device is vibrating at a rate indicative of natural tremors of a human body comprising: receiving with the circuitry an electronic signal from the accelerometer indicative of movement of the electronic device; for each set of samples of a plurality of sets of samples of the signal, determining with the circuitry a value of a magnitude of the set of samples for a first range of frequencies indicative of natural tremors of a human body; determining with the circuitry a value of a magnitude of the set of samples for a second range of frequencies higher than the first range; and producing an output with the circuitry indicating detection when the difference between the value of the magnitude of the first range of frequencies and the value of the magnitude of second range of frequencies is greater than a threshold value; and producing an output with the circuitry indicating that the electronic device is vibrating at a rate indicative of natural tremors of a human body when a threshold number of sets of samples within a predetermined time period produce an output indicating detection; and operating with the circuitry the electronic device in response to whether the electronic device is vibrating at a rate indicative of natural tremors of a human body while the electronic device is not physically enclosed in a small space.
