Abstract
Various methods for monitoring movement of a person involve using a sensor to generate a signal in response to movement of a person. In one embodiment, a characteristic in the signal is identified that indicates the person is walking or running and, in response to identifying the characteristic, a timer is started. In another embodiment, after the person has begun walking or running, a characteristic in the signal is identified that indicates the person has ceased walking or running and, in response to identifying the characteristic, an action is taken. In another embodiment, a characteristic in the signal is identified that is indicative of a foot of the person being in motion and, in response to identifying the characteristic, a timer is started. In another embodiment, after a foot of the person has been in motion, a characteristic in the signal is identified that is indicative of the foot ceasing to be in motion and, in response to identifying the characteristic, an action is taken. In another embodiment, in response to identifying that the person is not walking or running, a characteristic in the signal is identified that indicates the person has begun walking or running and, in response to identifying the characteristic, an action is taken. In another embodiment, in response to identifying that a foot of the person is stationary, a characteristic in the signal is identified that indicates the foot is in motion and, in response to identifying the characteristic, an action is taken.
