Abstract

An electronic device creates a table for mapping a plurality of pressure values corresponding to a plurality of numerical values, and stores the pressure mapping table in a memory. The electronic device detects a touch on a touch panel of the electronic device and detects a value of the pressure of the touch. The electronic device obtains a numerical value corresponding to the detected pressure value in the pressure mapping table. The electronic device generates a password code as a result of user input based on the numerical value.

Claims

1. An electronic device, comprising:

a touch panel detecting a touch operation on the touch panel and a pressure value applied by the touch operation;

a memory storing a pressure mapping table that maps relationships between a plurality of pressure values of the touch operation and a plurality of numerical values;

an query module obtaining a numerical value corresponding to the pressure value in the pressure mapping table in response to the touch operation; and

a password input module generating a first password code based on the numerical value.

2. The electronic device of claim 1, further comprising:

a display unit; and

a display module displaying the pressure value on the display unit.

3. The electronic device of claim 1, wherein the numerical values are decimal digits.

4. The electronic device of claim 2, wherein the display module further displays a grid on the display unit, wherein the grid comprises a plurality of rows, a plurality of columns, and a plurality of squares formed by the plurality of rows and columns.

5. The electronic device of claim 4, wherein each of the plurality of squares is positioned as an X-coordinate value and an Y-coordinate value according to a row location index value and a column location index value.

6. The electronic device of claim 5, wherein the password input module further generates a second password code based on the X-coordinate value, the Y-coordinate value and the numerical value.

7. A password input method for an electronic device comprising a touch panel and a memory, the method comprising:

detecting a touch operation on the touch panel and a pressure value applied by the touch operation;

storing a pressure mapping table in the memory that maps relationships between a plurality of pressure values of the touch operation and a plurality of numerical values;

obtaining a numerical value corresponding to the pressure value in the pressure mapping table in response to the touch operation; and

generating a first password code based on the numerical value.

8. The method of claim 7, further comprising displaying the pressure value on a display surface of the touch panel.

9. The method of claim 7, wherein the numerical values are a decimal digits.

10. The method of claim 8, further comprising:

displaying a grid on the display surface of the touch panel, wherein the grid comprises a plurality of rows, a plurality of columns and a plurality of squares formed by the plurality of rows and columns.

11. The method of claim 10, wherein each of the plurality of squares is positioned as an X-coordinate value and an Y-coordinate value according to a row location index value and a column location index value.

12. The method of claim 11, further comprising generating a second password code based on the X-coordinate value, the Y-coordinate value and the numerical value.
