If you click on the brush button at the bottom of these characters, the correct brush movements and order are recommended, and the infant starts brushing in the brushing order.

The analysis step S500 determines whether the brushing action pattern in the start step S400 is a pre-input brushing order and a brushing action pattern. That is, in the analysis step S500, the infant confirms whether the toothbrush is brought into contact with the tooth according to the pre-input toothbrushing order. And to check whether the toothbrush is moved in accordance with a pre-input brush movement pattern.

The proceeding step S600 confirms whether the same toothbrushing pattern is the same as the analysis step S500, and proceeds to the next brushing sequence by providing suitable feedback. More specifically, the feedback of the progressing step S600 is performed by repeating the state in which the infant tilts the angle of the upward and downward rotation of the bristles about 45 degrees with the toothbrush placed on the teeth by the display unit 220 of the start step S400 . At this time, if the movement tracking sensor unit 100 senses the movement and the rotation angle of the toothbrush and the control unit 240 determines that it is not the correct toothbrushing operation through the analysis step S500, the control unit 240 determines " The phrase " please correct me " is displayed on the display unit 220 and the same voice as the phrase is outputted from the voice output unit 250 described later.

Thus, the progress step S600 allows feedback to improve erroneous brushing habits.

In the step S600, the overall shape of the tooth is provided as a sub-screen on one side of the bottom of the screen of the display unit 220. [ And the teeth displayed on the sub screen are provided with a color that can identify the position where the toothbrush is currently in progress. For example, the teeth appear in white color and a red color mark appears on the teeth at the position where the toothbrush is in progress.

In the compensation step S700, when the number of brushing completion times reaches 1 to n, which is set in advance by the parent through the progressing step S600, compensation is performed. That is, the compensation step (S700) is intended to provide an interest in correctly performing the erroneous brushing process during the above-described stepwise brushing process. In addition, the reward presents toys, coupons, dolls or goods desired by the infant.
