Accordingly, when the user sequentially writes a plurality of characters K, I, M, A, and B (or numbers, symbols, and figures) on the gesture pad pad50, the gesture recognition unit 24 may write on the gesture pad pad50. Identification information of the valid gesture corresponding to the written character is sequentially obtained and transmitted to the electronic device 36. Then, the electronic device 36 obtains button information mapped to each of the identification information of the plurality of valid gestures transmitted as a user input value, performs a user input operation, and simultaneously recognizes the characters currently input. To display it.

Basically, everyone has their own handwriting with unique strengths, speeds, directions, and habits, and these features are reflected equally even if you use your fingers without using a pen or pencil, so the picture gestures, or characters, drawn on the gesture pad It is easy to detect whether the numbers, symbols and figures are of the authenticated user.

The electronic device may be used only by the authenticated user by setting the picture gesture corresponding to the handwriting of the authenticated user as a valid gesture in advance. In this case, since there is no trace of the picture gesture on the gesture pad, the possibility of handwriting theft can be prevented in advance.

5 is a view for explaining a gesture-based user input method according to an embodiment of the present invention.

First, a user draws a gesture on the gesture pad 21 implemented as shown in FIG. 3A or 3B (S1).

Then, the gesture pad 21 generates a sound or vibration corresponding to the picture gesture currently drawn by the user, and the gesture detector 22 detects the sound or vibration of the gesture pad 21 and transmits the sound to the gesture recognizer 24. (S2).

The gesture recognition unit 24 analyzes the sound or vibration transmitted from the gesture detecting unit 22 to extract feature data of the picture gesture drawn by the user (S3), and then retrieves reference data stored in the gesture storage unit 23. It is checked whether reference data that matches the extracted feature data exists (S4).

As a result of checking in step S4, if there is reference data that matches the extracted feature data (S5), the gesture recognition unit 24 obtains identification information of the valid gesture mapped to the reference data (S6), and obtains the validity. The gesture identification information is transmitted to the electronic device 30 (S7).

  Accordingly, the electronic device 30 checks what function or button information is requested by the current user through identification information of the valid gesture, and performs a corresponding function or inputs the corresponding button information to provide a service required by the user. .

On the other hand, if there is no reference data that matches the extracted feature data as a result of checking in step S4 (S5), the gesture recognition unit 24 confirms that the input operation performed by a user's mistake or meaningless picture gesture ends the current operation (S8).
