detailed description

The present invention provides a method and an apparatus for unlocking a touch screen device. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

The touch screen device of the present invention is an electronic device with a touch screen, and can be a portable electronic device with a touch screen mobile phone, a computer, a tablet, an MP3, an MP4, a PSP, a POS machine, and the like. The touch screen is used for display and touch screen operation. In order to prevent misoperation and illegal use by others, the touch screen device is now set to manually lock the screen, or automatically enters the locked state when no operation or touch is detected within a preset time. When the touch screen of the device is in a locked state, the user cannot perform a touch operation through the touch screen.

Under the prior art, the touch screen itself cannot directly collect high-quality fingerprint images for identity verification, and an object of the present invention is to provide a method for unlocking a fingerprint, which is an analog verification fingerprint for unlocking the touch screen, but substantially Unlocking the touch screen through behavior recognition improves the unlocking fun and user experience while ensuring the security of the touch screen device unlocking.

Referring to FIG. 1 and FIG. 2, a method for unlocking a touch screen device according to a first embodiment of the present invention includes the following steps:

Step S10: When the touch screen 30 of the device is in a locked state, contact with the touch screen 30 is detected.

Step S20: When the contact with the touch screen 30 is detected, an imitation fingerprint collection area 40 is displayed on the touch screen 30, wherein the preset fingerprint image 50 is displayed in the imitation fingerprint collection area 40.

The fingerprint-like fingerprint collection area 40 is an area for simulating the fingerprint of the user, and the size thereof may be set to be slightly larger than the general fingerprint size, and the position may be set to be fixedly displayed at the center position of the touch screen 30 or other specific positions.

Preferably, as shown in FIG. 2, the fingerprint-like fingerprint collection area 40 can also be disposed to be displayed with the contact point 20 as a center position, so that the user can touch any position of the touch screen 30, and the fingerprint-like collection area 40 also follows. The user's contact point is generated, which enhances the user's pleasure in unlocking the touch screen, and also ensures that the user's finger is just above or near the fingerprint-like fingerprint collection area 40 after the fingerprint-like fingerprint collection area 40 is displayed, thereby avoiding the user's return. It is necessary to move the hand to find the fingerprint-like collection area displayed by other fixed positions, which saves the operation time of subsequent pressing contact in the fingerprint-like collection area 40, and improves the unlocked user experience.

Step S30: detecting a press contact with the fingerprint-like collection area 40, and acquiring a position and a contact time of the first contact point of the press contact.

When the user presses the fingerprint-like collection area 40 of the touch screen 30 with a fingertip, the touch screen 30 first detects the position of the first contact point, and then with the fingertip fingerprint completely with the fingertip When the touch screen 30 is in contact with the contact, the contact between the two contacts becomes a contact of the face by the contact of a single point. When pressing the contact, the user can control the position range of the first contact point by slightly adjusting the position and angle of the fingertip pressing contact, and it is difficult for others to observe or guess the position or effective position of the user's first contact point. It is even impossible to imagine that the touch screen unlocking method of the present invention limits the effective position range of the first contact point.

In the first embodiment of the invention, the contact time of the press contact is obtained by the touch screen device detecting the time from the start of the contact to the end process. It can be understood that, in order to facilitate the user to acquire and control the time of each pressing contact, the contact time of the user's pressing contact can be dynamically displayed when the user presses the contact, and the user can conveniently determine and control the time of the pressing contact.

Of course, the contact time of the pressing contact can be acquired in the following three embodiments or other manners, so that the user can intuitively determine and control the contact time of the pressing contact, and enhance the realism and contact time of the fingerprint capture by the analog touch screen as the unlocking condition. Concealment improves the fun of unlocking the touch screen.

In another embodiment of the present invention, a scanning beam with a constant speed and continuous reciprocating motion is displayed inside the fingerprint-like collection area 40, further simulating the fingerprint collection interface, and also allowing the user to intuitively determine the moving distance or the round-trip path of the scanning beam. The contact time of the press contact is determined by dividing the distance of the scanning beam movement by a preset speed. Specifically, in the embodiment of the present invention, the scanning beam is arranged to reciprocate up and down in the center of the fingerprint-like collection area 40 at a fixed speed of one round trip per second, and the scanning beam starts to go from top to bottom when the user presses the contact. Movement, when the scanning beam is moved halfway to the lower end of the fingerprint-like acquisition area 40, the user can intuitively determine that the pressing contact time is 1.5 seconds, so that the user can control the time of the pressing contact according to the moving distance of the scanning beam. In this embodiment, the displayed fingerprint image, the animation effect of the scanning beam continuing to reciprocate motion, and the user's finger pressing and touching the fingerprint-like fingerprint collection area 40 cause great deception, causing others to mistakenly believe that the user is collecting fingerprints through the touch screen. Verify and unlock. Moreover, the scanning beam in the fingerprint image is a universal animation effect of prompting the user to input a fingerprint, and the process of intuitively controlling the time of pressing the contact by controlling the moving distance of the scanning beam when the user presses the unlocking is difficult to be observed or even guessed by others. It has a strong concealment and improves the fun of unlocking the touch screen.

In still another embodiment of the present invention, a scanning beam of a uniform continuous cyclic motion is displayed at the edge of the fingerprint-like acquisition area 40 to further simulate a fingerprint collection interface, and at the same time, the user intuitively determines the moving distance of the scanning beam. The contact time of the contact is determined by the distance traveled by the scanning beam and the preset speed. Specifically, in the embodiment of the present invention, the scanning beam is arranged to circulate clockwise or counterclockwise at the edge of the fingerprint-like acquisition area 40 at a fixed speed of a closed loop every 2 seconds, and the user is detected when the pressing contact is detected. The beam starts to move from the position of 12 o'clock. When the scanning beam moves 1.25 closed loops to reach the position of the fingerprint capture area 40 at three o'clock, the user can intuitively determine that the pressing contact time is 2.5 seconds, so that the user can The moving distance of the scanning beam is a good control of the time of pressing the contact.

In still another embodiment of the present invention, the edge of the fingerprint-like collection area 40 continuously changes color continuously according to a preset color sequence, so that the user intuitively determines the process of color change, and the contact time of the press contact is through the The color of the start of the contact is pressed and the preset color change speed is determined. It can be understood that the control principle of the pressing contact time of this embodiment is similar to that of the above embodiment, and the specific implementation details described above may be referred to, and details are not described herein again.

Step S40: If it is detected that the first contact point falls within the preset area in the fingerprint-like fingerprint collection area 40 and the contact time falls within the preset time range, the device is switched to the unlocked state of the user interface; It is detected that the first contact point does not fall into the preset area in the fingerprint-like collection area 40 and the contact time does not fall within the preset time range, and the device is kept in the locked state of the user interface.

The step of determining whether the first contact point falls within the preset area in the fingerprint-like fingerprint collection area 40 includes: acquiring the position of the fingerprint-like fingerprint collection area 40; acquiring a preset area position range of the first contact point; Whether the position of the first contact point falls within the preset area position range.

Further, before the unlocking by the unlocking method of the touch screen device, the method further includes: pre-setting the area of the first contact point in the fingerprint-like collection area 40: pre-dividing the fingerprint-like collection area 40 into multiple Area; preset at least one area is the effective contact area of the first contact point. Referring to FIG. 3, the fingerprint-like fingerprint collection area 40 is divided into 6 columns and 3 rows of 18 regions, and the 5th row and the 3rd region 60 are set as effective contact regions of the first contact point. Here, the effective contact area of the first contact point is not the fixed area position of the touch screen 30, but the relative area position in the fingerprint-like collection area 40 is the position of the fingerprint-like collection area 40. Change and change. Of course, the way of dividing the area, the number of the area, the location and the number of the first contact point effective area can be personalized according to the user's preference and security requirements. Preferably, the boundary of the divided area can also be displayed on the touch screen so that the user can quickly and accurately find the effective contact area of the first contact point.

It can be seen that the unlocking method of the touch screen device provided by the present invention is to simulate the user to collect the fingerprint of the user through the touch screen 30 for fingerprint identity verification, and substantially determines the position of the first contact point and the pressing contact when the user unlocks. The behavior of time is triggered to unlock, which is extremely concealed. It is difficult for others to observe or crack the effective contact area and pressing contact time of the first contact point of the user's preset pressing contact, and it is almost impossible to think of it. The position of the first contact point is limited to the unlock condition, which improves the security of the touch screen unlocking. In addition, the appearance of the simulated fingerprint recognition is extremely deceptive, which can make others mistakenly believe that the touch screen device must collect fingerprints for unlocking, which acts as a deterrent to the illegal unlocking behavior, effectively suppressing the intention of others to attempt illegal unlocking. This also indirectly improves the security of the touch screen unlocking. At the same time, the analog touch screen captures the fingerprint unlocking scheme, which also improves the interest of unlocking and enriches the user's touch screen operation experience.
