    摘要: A system and method for monitoring and analyzing activities of a person operating a machine, particularly driving a vehicle, is provided. A first magnet is attached to a hand of the person and a second magnet is attached to the head of the person. A smart watch having a magnetometer is attached to the other hand of the person. The magnetometer is in magnetic communication with both the first magnet and the second magnet to generate a first magnetic signal and a second magnetic signal. Both signals can be received by a processor and applied to mathematical models by the processor to generate indicators representative of positions and motions of the hands and the head. An alarm can be generated based on the indicators.

    摘要: A system and method for monitoring and analyzing activities of a user operating an electric tooth brush having an electric motor. The magnetic field induced by motions of the electric motor can be detected by a sensor array to generate signals. The signals are processed to determine a position of the brush head and a roll angle of the brush head. Based on the position and roll angle of the brush head, the surface of the teeth of the user, which is being brushed by the brush head, can be determined. This operation can be repeated to determine whether all the surfaces of the teeth have been brushed.
