Referring to FIG. 2, FIG. 2 is a schematic flow chart of a second embodiment of a method for unlocking a pattern according to an embodiment of the present invention. The method for unlocking a pattern described in this embodiment includes the following steps:

S201. When the terminal is in the awake state, displaying M patterns on the touch screen of the terminal, where the M patterns include a N-type pattern, the N is an integer greater than 1, and the M is greater than the An integer of N.

In a specific implementation, when the terminal is in the awake state, M patterns may be displayed on the touch screen, wherein the M patterns may be N-type patterns, N is an integer greater than 1, and M is an integer greater than N.

Further optionally, the M patterns may be derived from K patterns, and in the state in which the terminal is awakened, M patterns of the K patterns are displayed, and K is an integer greater than M.

Optionally, the terminal may display the M patterns in a preset order, and the preset order may be a random order, a fixed order, or a plurality of different pattern display sequences respectively displayed at every preset time or at different occasions.

S202. Determine a pressing parameter of a P pattern in a K-type pattern in the N-type pattern, where the pressing parameter includes P pressing force values and a pressing order corresponding to the P patterns, and the P patterns At least one of each of the K-type patterns is included, the K being an integer greater than 1 and less than the N.

In a specific implementation, the terminal may select P patterns from the N-type patterns, the P patterns are from the K-type pattern in the N-type pattern, and the P is an integer greater than or equal to K, that is, the P patterns include at least the K-type One of each of the patterns in the pattern, when the user presses the P patterns, may determine a pressing parameter corresponding to the P patterns, and the pressing parameter may include one pressing parameter. Further, the terminal may generate a pressing parameter according to a preset manner by pressing the P pressing parameters obtained by pressing the P patterns. For example, the P pressing parameters may be averaged to obtain a check value as a pressing parameter of the P patterns.

Optionally, the pressing parameter may include P pressing force values and a pressing order corresponding to the P patterns, wherein the P pressing force values are in one-to-one correspondence with the pressing operations of pressing the P patterns, that is, pressing the P patterns. The pattern i in the middle can generate a pressing force value.

S203. Calculate the P pressing force values according to a preset rule to obtain a check value.

In a specific implementation, the terminal may perform the average operation of the P pressing force values to obtain the check value. Alternatively, the terminal may determine a maximum pressing force value and a minimum pressing force value among the P pressing force values, and perform a variance calculation on the remaining pressing force values of the P pressing force values to obtain a check value. The preset rule is not limited to the above two ways of obtaining the check value. The terminal may also separately encode P pressing force values to obtain a check value. For example, taking the pressing force value as an example, the pressing force value corresponds to five codes of A1-A5, the pressing force value is greater than 0 cattle and less than 12 cattle corresponding to A1, the pressing force value is greater than or equal to 12 cattle and less than 24 cattle corresponding to A2, pressing force The value is greater than or equal to 24 cattle and less than 36 cattle corresponding to A3, the pressing force value is greater than or equal to 36 cattle and less than 48 cattle corresponding to A4, and the pressing force value is greater than or equal to 48 cattle corresponding to A5, then in the case of P being 3, 3 The pressing force values are: 8 cattle, 24 cattle, 48 For cattle, the check value is A1A2A5.

S204. Determine whether the check value is in a preset interval and whether the pressing sequence is consistent with a preset pressing sequence.

In a specific implementation, the terminal may compare the check value with the preset interval, and determine whether the check value is in the preset interval, where the preset interval is a preset interval corresponding to the P value of the pressing force value. Range, the preset interval can be a range value. For example, if the check value is 5 and the interval range is [4, 8], the check value is in the preset interval. Further, the terminal may compare the pressing sequence with the preset pressing sequence to determine whether the two are consistent, for example, the pressing order is ABCDE, and the preset pressing order is BACDE, the two are inconsistent, and the preset pressing order is In the case of ABCDE, the pressing order is the same as the preset pressing order.

Further, the preset interval may be a fixed value, that is, the check value is equal to the fixed value, or the check value is to satisfy a certain relationship with the fixed value. For example, the check value may be divisible by the fixed value, or the product of the check value and the fixed value may satisfy a preset threshold.

S205. When the result of the determining is YES, perform an unlocking operation on the terminal.

In a specific implementation, when the pressing parameter and the preset pressing parameter are successfully matched, the terminal can be unlocked, so that the terminal enters a normal display interface, and the normal display interface can display a shortcut of each application in the terminal.

Optionally, in a case that the pressing parameter and the preset pressing parameter match are unsuccessful, the user is prompted to perform the unlocking again; further, if the user is in the preset number of times or the preset time, the pressing parameter and the preset pressing parameter are If the match is still unsuccessful, the terminal enters the shutdown state.

As a possible implementation manner, in this embodiment, after performing the steps S201 to S202, the terminal may further perform the following steps, that is, the terminal may first determine the P pressing force values and the preset P pressing strengths. Whether the values match; if the result of the determination is yes, the terminal determines whether the pressing order is consistent with the preset pressing order. Further, the terminal may first determine whether the P pressing force values match the preset P pressing force values; if the result of the determination is no, the terminal prompts the user to perform the pressing operation again. Optionally, the terminal determines whether the pressing sequence is consistent with the preset pressing sequence. If yes, the terminal performs an unlocking operation. If not, the terminal prompts the user to perform a pressing operation again.

In a specific implementation, when detecting that the user performs a pressing operation on the touch screen, the terminal may determine the position of the pattern pressed by the user through the position detection, and use the pressure sensor under the touch screen to detect the pressing force value of the position of the pattern pressed by the user, and simultaneously acquire The category identifier corresponding to the pattern, the category identifier is used by the user to mark the class name of the pattern. Further, the terminal acquires P velocity values of P patterns and K class identifiers corresponding to P patterns in the K-type pattern in the N-type pattern, wherein the N-type pattern corresponds to the N category identification codes one-to-one .

In a specific implementation, the terminal may generate a character string in the order of pressing the P class identifiers, and the string may be used as the pressing sequence corresponding to the P patterns.

For example, in the case where N is 4, the 4 types of patterns have 4 category identification codes, and the 4 types of patterns include the first type of patterns, the second type of patterns, the third type of patterns, and the fourth type of patterns. The category identification of the first type of pattern is coded as X1, the category identification code of the second type of pattern is X2, the category identification code of the third type of pattern is X3, and the category identification code of the fourth type of pattern is X4. When the user presses three patterns in sequence, one of the third type of patterns, one of the second type of patterns, and one of the fourth type of patterns, the generated character string may be X3X2X4, and the string is The pressing order of the three patterns corresponds.
