Background technique

With the continuous development and maturity of science and technology, many electronic devices tend to be portable. These portable electronic devices use a large number of large-screen touch screens as human-computer interaction devices. However, on many portable electronic devices, because there is no external protection device, users or other objects can easily inadvertently touch the screen of these devices, causing the device to be activated or mishandled.

In order to avoid the inconvenience caused to the user, these devices generally have a screen lock function in the standby state, that is, the screen is fixed in the standby state, so that the user cannot operate. Normal use can only be performed after the user unlocks the screen in a specific way.

The existing screen unlocking methods are mainly as follows:

One is the password unlocking method, that is, the user uses the virtual keyboard provided by the device screen to input a preset unlocking password to unlock. This method of unlocking requires the user to accurately remember the screen unlock code and enter it in the correct way. However, as the number of password combination keys increases, the memory requirements and input requirements of the user are also improved, which is inconvenient for the user to unlock. And this unlocking method is boring and monotonous, and it is not attractive to users;

The other is to use the more widely used reservation gesture mode, that is, after the user performs dragging, sliding, clicking, etc. on the screen, the device determines whether to unlock by determining whether the user's touch on the touch screen and the predetermined gesture are consistent. Such as Apple's hand-held unlock, Meizu M8's area touch and unlock, Google (Google) mobile phone's contact unlocking method. This method is simple in operation, beautiful in interface, and has a good user experience. It has been used on many portable touch-screen devices such as mobile phones and PDAs (Personal Digital Assistants). However, most of these methods are in contact position or The gesture track is fixed, and the operation interface is monotonous and lacks interest, which cannot meet the individual needs of the user.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

In this embodiment, a method for releasing a screen lock of a terminal is applied to a portable terminal device configured with a touch screen. As shown in FIG. 1, the method includes the following steps:

Step 10: After the unlocking application is started, displaying M images in the touch screen, wherein only one of the M images is identical; wherein M > N, and M and N are greater than A positive integer of 1; preferably, N=2, that is, among the M images displayed, one and only one pair of images are identical; in a specific implementation, the number M of images displayed on the touch screen can be set by the user. The display position of each image can be random, as long as the images do not overlap. Of course, the type of image to be displayed may be preset by the system, or may be obtained by the user through an external source such as a picture file or a camera.

Step 20: For the above N images, detecting whether the time interval between when the area where the first image is touched and when the area where the last image is touched does not exceed the pre-configured touch time difference; if not, Go to step 30; if it is over, wait for the touch again, go to step 20; Step 30, unlock the touch screen.

In addition, the setting of the number of images to be M can be limited by the system according to the size of the touch screen, to avoid the user setting value is too large, the screen display image is too small, and it is not convenient for the user to touch the operation. The touch time difference T can be directly set by the user according to his or her own situation, or the user can automatically adjust to the optimal value according to the sample by repeatedly touching the screen.

The following takes N=2 as an example. As shown in FIG. 2, the above process is further described.

Step 1: The user sets the screen unlock parameters according to their personal preferences. The set parameters include: image type, number of screen display images M ( Μ > 2 ), touch time difference T; as shown in Figure 3, the user sets the unlock image type to geometry by unlocking the parameter setting module, and the image appears. The number M is four, and the unlocking time difference T is 1000 milliseconds. Step 2: The user touches the screen to cause the unlock application to start. According to the setting in step 1, M images randomly appear in the touch screen area;

Of these M images, each image must be completely displayed on the terminal screen with no missing or overlapping. Different images should be clearly distinguished, which is convenient for users to distinguish and identify. The area of each image is suitable for the user to touch.

Step 3: The terminal waits for the user to touch the area where the image is located. If the user touches the point Pi on the screen at the time point ti, the touch point belongs to the area Ri (Pi e Ri ) of the certain image, and the image has a matching image in the currently displayed image (ie, If the image is identical to another image, it is determined that the touch is a valid touch, so proceed to step 4; otherwise, proceed to step 3 to wait for the touch;

Step 4: Wait for the user to touch again. If the user touches the point Pi+1 (Pi+1 G Ri+1 ) in the region Ri+1 where the effective image is located at the time point t ( i+1 ), the i+1th touch and the first The time difference of the i touches is not greater than T (ie, t ( i+1 ) - ti T ), and the image represented by the region Ri+1 matches the image represented by Ri (ie, the two images are identical), and the unlocking is successful. Otherwise, return to step 3 and wait for the touch again.

As shown in FIG. 4, at least the following modules need to be included in the unlocking system described in this embodiment:

(1) unlocking a parameter setting module, the module is configured to provide an interface for the user to personalize the screen unlocking parameter setting of the touch screen device, and save the customized related parameter;

(2) unlocking an image generation module, the module is configured to generate an unlock pattern according to parameters in the screen unlock parameter setting module, wherein only one of the N images is identical, and the size and position of each image are calculated according to the actual touch screen size. And displayed on the touch screen;

(3) a touch validity determination module, the module is configured to obtain a touch position of the user on the touch screen, and determine the validity of the user touching the screen;

(4) touching the image matching module, and setting a time interval between detecting that the area from the first image is touched until the area where the last image is touched is not exceeded in the N images. When the touch time difference is small, an unlock command is sent to the unlocking module;

(5) The unlocking module is set to release the locked state of the touch screen after receiving the unlocking command sent by the touch image matching module, and enter the operable interface. After the user requests to unlock, the phone unlock program starts. Figure 5 shows that according to the user's settings, four geometric figures appear randomly on the screen of the mobile phone, and the areas represented by them are Rl ( (xll, yll), (xl2, yl2)), R2 ((x21, y21), (x22). , y22 ) ) , R3 ( (x31, y31 ) , (x32, y32) ) , R4 ( (x41, y41 ) , (x42, y42 ) ) . The images in R1 and R3 match.

At the time point ti, the user touches the point PI (xl , pyl ) on the screen for the first time, and determines whether the PI is a valid touch. Since the Pi is in the image area R1, it is regarded as an effective touch, waiting for the user to touch again, and the edge of the R3 area is blinking or bolding to give the user a pairing prompt.

If the user touches the point P2 (px2, py2) on the screen at the i+1th time point t (i+1), and t ( i+1 ) - ti Τ. Judging the P2 coordinates and confirming that P2 is in the R3 area, the matching is successful and the screen unlocking ends. If the user touches the point P3 (px3, py3) on the screen at the i+1th time point t (i+1), JLt (i+1) - ti<T, since the i+1th touch P3 The image in the area does not match the image touched by the ith, so it continues to wait for the user to touch again. The method of judging the subsequent operations is similar, and the unlocking operation is performed until the touch is successfully matched.
