detailed description

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

Touch screens have been widely used in mobile phones, computers, tablets, MP3, MP4, PSP, POS and other electronic devices. In order to prevent misuse and illegal use by others, there are now touch screen settings that can manually lock the screen, or automatically enter the locked state when no operation or touch is detected within the preset time. When the touch screen is in the locked state, the user cannot perform the touch operation through the touch screen, thereby effectively avoiding misoperation and illegal operation by others.

Under the prior art, the touch screen itself cannot directly collect high-quality fingerprint images for identity verification, and the purpose of the present invention is to provide a method for unlocking a fingerprint, simulating a fingerprint for unlocking the touch screen, and substantially pressing The contact time of the contact and the behavior recognition of the contact area are unlocked by the touch screen, and the unlocking fun and user experience are improved while ensuring the security of the touch screen unlocking.

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

Step S10: When the touch screen 30 is in the 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 acquisition area for simulating the collection of user fingerprints, and the size thereof may be set to be slightly larger than a general fingerprint size and the area of the area is about 1.5 times the fingerprint area of the user's fingertip, and the position may be set to be in the The center position of the touch screen 30 or other specific position is fixedly displayed.

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.

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 on the touch screen 30 when the user presses the contact, and the user can conveniently determine and control the pressing contact. Contact time.

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

Of course, in order to allow the user to intuitively determine and control the contact time of the pressing contact, the realism and the contact time of the simulated touch screen to capture the fingerprint unlocking are enhanced as the concealment of the unlocking condition, and the interest of the touch screen unlocking is improved, and the pressing contact is improved. The contact time can be obtained by the following embodiments or other means.

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.

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 first contact point, and then gradually contacts the touch screen 30 as the fingertip fingerprint gradually contacts. The contact between the two becomes a contact of the face by the contact of a single point. Moreover, the contact area of the fingertip pressing contact gradually increases as the pressing force increases, up to the maximum contact area. Therefore, when pressing the contact, the user can control the contact area range by slightly adjusting the position, angle and strength of the fingertip pressing, and it is difficult for others to observe or guess the user's preset contact area range, or even It may be conceivable that the touch screen unlocking method of the present invention limits the preset contact area range, but simply considers that the user only unlocks the fingerprint by the touch screen.

Step S40: If the contact time of the pressing contact is detected, and the contact area falls within a preset contact time range and a preset contact area range respectively, the terminal is switched to an unlocked state of the user interface.

It can be understood that if it is detected that the contact time and the contact area of the pressing contact do not fall within the preset contact time range and the preset contact area range respectively, the terminal is kept in the locked state of the user interface.

Further, before unlocking by the unlocking method of the touch screen described above, the time range of the pressing contact should also be set in advance, and can be set according to the user's operating habits and the degree of difficulty in cracking. For example, the time range for setting the pressing contact is 0.5-1 second, and the time range setting is very short, which is beyond the time range of 2-3 seconds of the conventional fingerprint collection. When the user touches the fingerprint-like fingerprint collection area 40, the other person can only It is simply considered that the user only unlocks the fingerprint by the touch screen, and it is difficult to observe or guess the preset contact time range of the user, and it is even impossible to think that the touch screen unlocking method of the present invention limits the contact time of the pressing contact.

Similarly, further, before unlocking by the unlocking method of the touch screen, the contact area range of the pressing contact should be set in advance, and it can be set to a fixed value range, or the ratio of the area of the fingerprint-like collection area 40. range. For example, the contact area of the pressing contact is set to be 30% to 50% of the area of the fingerprint-like collection area 40. When the touch screen is unlocked, the user needs to control the position, angle and strength of the fingertip pressing, and the fingertip is slightly erected to A larger angle enables the actual pressing contact area to fall within this predetermined area, and the user controls the contact area of the pressing contact by adjusting the pressing contact behavior.

It can be seen that the unlocking method of the touch screen device provided by the present invention is, on the surface, an act of simulating a user to collect a user fingerprint through the touch screen 30 for fingerprint identity verification, and substantially determining the contact time and contact area of the pressing contact when the user unlocks. It is difficult for other people to observe or break the contact time and contact area of the user's preset pressing contact, which is extremely concealed, and it is even almost impossible to limit the contact time and the contact area to the unlocking condition. Improved security for 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.
