Abstract
A three-axis acceleration sensor is mounted to a body of an electric toothbrush. A CPU detects the three-dimensional attitude of the body based on an output from the acceleration sensor and, based on the attitude of the toothbrush, estimates which portion is being brushed. Then, the CPU measures by using a timer a brushing time of the portion being brushed. Results of brushing for each portion are evaluated and outputted based on the measured brushing time.
