When the user presses the display screen B3 on the touch screen 12 and the pressed position moves from the block B3 to the block B8, the touch screen 12 generates a table. A touch signal that is moved from the block B3 to the movement track of the block B8 is displayed (step S23).

The processing unit 16 exchanges the display position of the tile B3 originally displayed at the first position with the tile B8 originally displayed at the second position according to the touch signal, so as to move the tile B3 from the first position to the second position (step S25). ), as shown in Figure 6. Here, the terms "first" and "second" are used to mean two different display positions, and are not intended to be limited to a specific display position. In other words, the first position is used to indicate the display position where the tile is moved, and the second position is used to indicate the display position where the same tile is moved.

Moreover, the processing unit 16 detects the tiles B2, B7, tiles B8, B4 or tiles B18, B19 of the adjacent and identical features in the unlocking icon 121 (step S27), and determines adjacent according to an unlocking condition. Such a combination pattern composed of tiles of the same feature is, for example, a rectangle formed by tiles B2 and B7, a rectangle formed by tiles B8 and B4, or a rectangle formed by tiles B18 and B19 (step S29). In this embodiment, in step S27, the processing unit 16 detects the tiles B2, B7, tiles B8, B4 or tiles B18, B19 adjacent to the same color in the unlocking icon 121.

Here, the unlocking condition includes a setting graphic. Hereinafter, the cross pattern shown in FIG. 7 in the setting pattern 123 will be described in detail as an example.

In some embodiments, referring to FIG. 8, when the processing unit 16 detects (determines) that the combination pattern does not conform to the setting pattern (step S31), the processing unit 16 does not change the locking mode of the mobile device 10. The number of movements is accumulated (step S33).

When the processing unit 16 confirms that the number of movements has reached a predetermined number of times (step S35), the unlock map 121 is reset (step S37), for example, the position of the blocks B1 to B25 in the unlock map 121 is randomly set.

When the processing unit 16 confirms that the number of movements has not reached the predetermined number of times (step S35), it continues to detect the tiles of the adjacent and identical features in the unlocking icon 121 according to the unlocking conditions (ie, step S23 to step S31).

When the user presses the display block B15 on the touch screen 12 again and the pressed position is swept from the block B15 to the block B13, the touch screen 12 generates a touch signal indicating the movement track moved from the block B15 to the block B13. (Step S23).

The processing unit 16 exchanges the display position of the tile B15 originally displayed at the first position with the tile B13 originally displayed at the second position according to the touch signal, so as to move the tile B15 from the first position to the second position (step S25). ), as shown in Figure 9. Here, the processing unit 16 successively performs step S27 to step S35). When the processing unit 16 confirms that the number of movements has not reached the predetermined number of times (step S35), it continues to detect the tiles of the adjacent and identical features (colors) in the unlocking icon 121 according to the unlocking conditions (ie, steps S23 to S31).

When the user successively presses the display panel B19 on the touch screen 12 and the pressed position is swept from the block B19 to the block B14, the touch screen 12 generates a touch signal indicating the movement track moved from the block B19 to the block B14.

The processing unit 16 exchanges the display position of the tile B19 originally displayed at the first position with the tile B14 originally displayed at the second position according to the touch signal, so as to move the tile B19 from the first position to the second position (step Step S25), as shown in Fig. 10. Then, the processing unit 16 successively performs step S27 to step S31).

When the processing unit 16 detects (determines) that the combined pattern (consisting of blocks B3, B12, B15, B18, B19) conforms to the setting pattern (step 31), the processing unit 16 sets the mobile device 10 from a locked mode. Switching to a normal mode (step S39).

In some embodiments, referring to Figures 11 and 12, after the unlock icon 121 is displayed, the processing unit 16 initiates timing (step S22). Herein, the processing unit 16 may start timing in response to the display of the unlocking icon 121, or start the timing in response to the first touch signal displayed by the unlocking icon 121, or respond to the first image after the unlocking icon 121 is displayed. The block moves to start timing and the like.

When the processing unit 16 detects (determines) that the combination pattern does not conform to the setting pattern (step S31), the processing unit 16 does not change the lock mode of the mobile device 10, and confirms the accumulated time according to a predetermined time (step S36). .

When the processing unit 16 confirms that the accumulated time has reached the predetermined time (step S36), the unlock icon 121 is reset (step S37). On the other hand, when the processing unit 16 confirms that the accumulated time has not reached the predetermined time (step S36), it continues to detect the adjacent and identical features (colors) of the unlocking icon 121 according to the unlocking condition (ie, steps S23 to S31). ).

In some embodiments, the unlocking condition may further include a setting feature; for example, one of the colors of all of the tiles, one of the icons of all of the tiles, or a combination of the icons.

Hereinafter, the red cross shape shown in FIG. 7 with the unlocking condition will be described as an example. In other words, the setting feature is red and the setting graphic is a cross.

In some examples, in step 27, processing unit 16 may only detect tiles that are adjacent in the unlock icon 121 and that have a set color (ie, red). In step S31, the processing unit 16 only needs to determine whether the combined pattern conforms to the setting pattern.

In addition, in step 27, the processing unit 16 may also be a tile of adjacent and the same color (not limited to the set color), and in step S31, the processing unit 16 simultaneously determines whether the combined pattern conforms to the set color and the setting graphic.

In some embodiments, in step 25, the processing unit 16 may also pass the block in the first position in the first position according to the touch signal, and sequentially exchange the position with the adjacent tile along the moving track to be the first position. Move to the second position.

For example, referring to FIG. 13, when the user presses the display screen B8 on the touch screen 12 and the pressing position is swiped from the block B8 to the block B15, the touch screen 12 generates a representation to move from the block B8 to the block. The touch signal of the moving track of B15. In other words, the beginning of the movement trajectory is the first position where the current tile B8 is located, and the end of the movement trajectory is the second position where the current tile B15 is located.

During the sliding process, when the pressing position is sequentially slid from the block B8 through the block B3, the block B4, and the block B9 to the block B14, the processing unit 16 displays the original position in the first position according to the touch signal. Block B8 First exchange the display position with the adjacent tile B3, exchange with the tile B3, exchange with the adjacent tile B4, exchange with the tile B4, and then with the adjacent tile B9, and exchange with the tile B9. And adjacent block B14, as shown in Figure 14.

When the sliding position is continued to slide through the block B13 and the block B18 and slides to the block B19, after the exchange with the block B14, the processing unit 16 continues to exchange the display position of the block B8 with the adjacent block B13 according to the touch signal. It is exchanged with the tile B13 and then with the adjacent tile B18, and with the tile B18 and then with the adjacent tile B19, as shown in Fig. 15.

When the sliding position is continued to slide through the block B13 and slides to the block B15 at the second position, after the exchange with the block B19, the processing unit 16 continues to exchange the block B8 with the adjacent block B13 according to the touch signal.
