Description
Technical Field
The invention relates to the field of communication, in particular to a multi-touch unlocking method and an electronic device, and particularly relates to a multi-touch unlocking method and an electronic device suitable for blind people.
Background
Along with the increasing popularization of electronic devices, especially, the rapid update of many intelligent electronic products including mobile phones, small notebooks, large notebooks, etc. makes the user demand for such products to be used more and more. Among them, unlocking, as an initial operation of opening the touch screen of the electronic device, is becoming more and more novel and various, and becomes a large aspect of attracting the eyes of the user.
Currently, many unlocking methods in the prior art may be easy to operate and convenient for common users, but for blind friends, many inconveniences are often accompanied when the users unlock the electronic device; even aiming at certain simple unlocking modes, the unlocking method is easy to operate, but has the defects of low safety factor, easy cracking and the like.
Specifically, the existing unlocking modes include sliding unlocking, password unlocking, digital unlocking, pattern unlocking, mixed password unlocking, face unlocking, fingerprint unlocking, and currently, non-security unlocking modes which are independently developed by some manufacturers and are not generally accepted yet. Among them, slide unlocking, i.e., the most basic unlocking manner achieved by sliding a screen, is not preferable for this manner, and regardless of operability for blind users, only from the viewpoint of safety; password unlocking and digital unlocking are unlocking modes of safety factor control through setting of characters or numbers, and the mode is probably better in safety, but is not easy to master for blind users in operability; pattern unlocking is an unlocking mode of safety factor management and control through a preset sliding track of nine points, and the mode is unsatisfactory in safety and operability; the hybrid password unlocking is an unlocking mode for safety factor control in a character and number combined mode, and the various and complicated unlocking modes are not preferable only in view of operability; the face unlocking is an unlocking mode of identifying the data of the face by a camera and recording and identifying the face to control the safety factor, and due to the limitation of the prior art in identification, the identification degree is low and the safety is poor; fingerprint unlocking is an unlocking mode of controlling safety factors by recording fingerprint storage data and identifying personal fingerprints, and by the aid of the existing technology, whether fingerprints are correct or not is intelligently judged, the source of the fingerprints cannot be judged, a fingerprint identifier can be bypassed by manufacturing a false fingerprint, and safety is poor; some manufacturers generally only gimmick and novelty unlocking modes, such as lock screen magazine, constellation vigor and the like, and no safety factor is generally available no matter operability.
Therefore, an unlocking method with higher safety factor, easier operation and handedness, especially suitable for the blind, becomes a popular theme developed by the technicians in the field at present.

Detailed Description
In an embodiment of the invention, as shown in fig. 1, the touch screen of the electronic device is divided into four different setting positions in a 2 × 2 manner, where the upper left position is a, the upper right position is b, the lower left position is c, and the lower right position is b. According to the setting of the unlocking method of the present invention, the limit operation action number of each multi-point operation is set to 4 times, so based on the premise that the touch screen is divided into four different setting positions a, b, c and d, the multi-point operation parameter combinations correspondingly obtained by each multi-point operation include different combination forms of single point, double point, three point and four point, specifically, the single point: a. b, c, d, two points: aa. ab, ac, ad, bb, bc, bd, cc, cd, dd, three points: aaa, aab, aac, aad, abb, abc, abd, acc, acd, add, bbb, bbc, bbd, bcc, bcd, bdd, ccc, cdd, ddd, four points: aaaa, aaab, aaac, aaad, aabb, aabc, aabd, aacc, aacd, aadd, abbb, abbc, abbd, abcc, abcd, abdd, accc, accd, acdd, addd, bbbb, bbbc, bbbd, bbcc, bbcd, bbdd, bccc, bccd, bddd, cccc, ccdd, cddd, dddd, and ddd, which are 4+10+20+35=69 combinations in total (permutation removal, combination only). The security of such an easy-to-operate parameter combination as a one-bit password is self-evident, in contrast, if the complexity of a conventional one-bit password is much greater than that of a conventional one-bit password. Of course, the specific parameter combinations listed here are only one multi-point operation, and in fact, in a specific embodiment, such multi-point operation may be set to 2-10 times, preferably 4 times, so that the complexity of the finally formed multi-point operation parameter combinations is more than conceivable, and therefore, the safety factor is further enhanced. Due to the reasonable setting of the unlocking mode, the operation mode can be ensured to be indirect and clear on the premise of the strongest safety factor, and particularly, the blind user can easily operate the upper hand, so that the outstanding beneficial effect is achieved.
In one embodiment, a multi-touch unlocking method for an electronic device, the electronic device including a touch screen, includes:
step S1: detecting at least one multi-point operation of a user in different set positions on a touch screen;
acquiring at least one group of multi-point operation parameter combinations according to parameters corresponding to different set positions;
step S2: comparing the at least one group of multi-point operation parameter combination with a preset unlocking parameter combination;
step S3: if the two are consistent, the unlocking is successful, and if the two are not consistent, the unlocking is failed.
Specifically, in step S1, as shown in fig. 3, it specifically includes the following steps:
the user starts to input the password, the time is counted from the first time of touching the screen by the user, the first multi-point operation is a single-point touch N1, when the time interval between the second time and the first time of touching is less than the set switching time T1, the first multi-point operation is a double-point touch N2, when the time interval between the third time and the second time of touching is less than the set switching time T1, the first multi-point operation is a three-point touch N3, when the time interval between the fourth time and the third time of touching is less than the set switching time T1, the first multi-point operation is a four-point touch N4 (the limit operation action number of each multi-point operation is set to 4), at the moment, the system automatically enters the second multi-point operation due to the maximum limit operation action number, wherein, during the first multi-point operation, the touch time interval is greater than the set switching time T1, the system also automatically enters a second multipoint operation;
and repeating the steps until the impact time interval is greater than the set judgment time T2, and automatically entering the next step.
Preferably, the maximum number of times of the multi-point operation is set, for example, four times, and when the number of times of the multi-point operation reaches four times, the system automatically proceeds to the next step regardless of whether the touch time interval is greater than the set judgment time.
It should be noted that, in the whole unlocking method step, no matter what interface is located, as long as the mobile phone is shaken, the system returns to the initial interface of unlocking again, and the unlocking is restarted.
Preferably, when the user starts to input the password, the system judges whether the user touches the screen for the first time, if not, waits, judges whether the waiting time exceeds the sleep time, if not, continues to wait, if yes, the screen is extinguished, and more preferably, the screen is extinguished to emit long vibration, or the screen is extinguished and then returns to the initial interface directly.

a user lights up a screen and enters an initial interface;
the user starts to input a password, the system judges whether the user touches the screen for the first time, if not, the system waits for the touch of the user, judges whether the waiting time exceeds the dormancy time, if not, the system continues to wait, if yes, the screen is extinguished, more preferably, the screen is extinguished to send long vibration, or the screen is extinguished and then directly returns to the initial interface;

by analogy, the system automatically enters the next step until the impact time interval is greater than 5s, preferably, the maximum number of times of multipoint operation is set, for example, four times, and when the number of times of multipoint operation reaches four times, the system automatically enters the next step no matter whether the impact time interval is greater than the set judgment time or not;
then the system compares the obtained multi-point operation parameter combination with a preset unlocking parameter combination;
if the two are consistent, the unlocking is successful, and if the two are not consistent, the unlocking is failed.
Preferably, in the whole unlocking method step, no matter what interface is located, as long as the mobile phone is shaken, the system returns to the original interface of unlocking again, and unlocking is restarted.
In one embodiment, the unlocking method further includes an unlocking mode setting step, including:
a user performs at least one multi-point operation setting at different setting positions on a touch screen;

the user starts to set a password, the system judges whether the user touches the screen for the first time, if not, the system waits for the touch of the user, judges whether the waiting time exceeds the dormancy time, if not, the system continues to wait, if yes, the screen is extinguished, more preferably, the screen is extinguished to send long vibration, or the screen is extinguished and then directly returns to the initial interface;
counting time from the first time of the screen touch of the user, wherein the first multipoint operation is a single-point touch N1', when the time interval between the second time and the first time is less than 200sm, the first multipoint operation is a double-point touch N2', when the time interval between the third time and the second time is less than 200sm, the first multipoint operation is a three-point touch N3', when the time interval between the fourth time and the third time is less than 200sm, the first multipoint operation is a four-point touch N4' (the limit operation action times of each multipoint operation are set to be 4 times), at the moment, as the maximum limit operation action times are reached, the system automatically enters the second multipoint operation, wherein, during the first multipoint operation, the touch time interval at any time is more than 200sm, the system also automatically enters the second multipoint operation;
by analogy, the system automatically enters the next step until the impact time interval is greater than 5s, preferably, the maximum number of times of multipoint operation is set, for example, four times, and when the number of times of multipoint operation reaches four times, the system automatically enters the next step no matter whether the impact time interval is greater than the set judgment time or not;
and then the system stores the preset unlocking parameter combination, and finally the setting is finished.

the system distinguishes the multipoint different settings of four areas a, b, c and d;
the permutation and combination of each password only calculates the combination mode, and does not calculate the permutation mode (for example, abcd is consistent with dcba, and the permutation mode is also four areas with four-point touch);
the system identifies that the time between every two clicks is calculated only after the user clicks for the first time;
the multi-point touch can only support four points at most, and when the password input or setting of a certain digit reaches four points, the password is automatically converted into the next digit;
the system needs to set a longer time interval (e.g., 5000 ms) to respond to the user's input completion or setup completion;
the system makes different types of prompts (sound and vibration) for unlocking success and unlocking failure.
Specifically, the digit judgment standard of the password is set to be that the interval between two adjacent clicks is greater than 200ms (millisecond), because the normal click frequency of a person is about 2t/s (two clicks per second), the normal click frequency is basically lower than the normal click frequency by taking 200ms as the judgment basis, namely, the interval between two adjacent clicks exceeds 200ms, and the next password is considered; if the time difference is less than 200ms, the previous password is judged to be multi-point touch, because the fingers cannot touch the screen at the same time when touching the screen at multiple points, a time difference must be specified, if the time difference is greater than the single-point touch, the password is regarded as multi-point touch, and when the clicking times of the same password in the time difference reach 4 times, the password automatically jumps to the next password; the system does not count time after the user lights the screen, and the system starts to count time only when the user starts to click and touches the screen for the first time; when the user finishes inputting, the system automatically judges whether the data is consistent with data preset by the user after 5 seconds, namely whether the interval between two adjacent clicks is more than 5 seconds, if not, the system considers that the user still inputs a password, if so, the user preset data is compared, and finally successful unlocking is realized; when the system compares preset data of a user, the system gives a vibration prompt and a sound prompt, if unlocking is successful, a correct prompt sound is given, a standby interface is entered, if unlocking is failed, a long vibration prompt is given for 1-2 seconds to prompt the user that unlocking is failed, and a screen is turned off.
In a particular embodiment, the unlocking system implements the following two aspects of operation.
Firstly, setting an unlocking mode:
(1) the user needs to enter a setting menu/a safety/unlocking mode and select the unlocking mode;
(2) entering an initial interface, dividing the interface into four areas a, b, c and d, wherein each area is used as a touch area which is separated from each other;
(3) the system judges whether the user touches the screen for the first time, if not, the system waits for the user to start touching, and the system judges whether the waiting time exceeds the dormancy time, if so, the screen is extinguished, and the initial interface is recovered; if not, continuing to wait for the user to start to touch;
(4) the system judges whether the user touches the screen for the first time, if so, the timing of the first password is started;
(5) when the user touches the screen for the first time to set a first password, the system considers that the user starts to set the password and takes the password as a single-point touch;
(6) at the moment, the system judges whether the user triggers the second touch within 200ms in the four areas, if so, the system sets the first password as a multi-point touch; judging whether the user triggers the third touch within 200ms in the four areas again until the user triggers 4 times of touches when setting the password, and automatically switching the system to set the next password; if not, the system automatically changes to set the next password;
(7) setting a second-bit password and a third-bit password in the same way by a user;
(8) the system judges whether the screen is touched by the user for the last time and is greater than or equal to 5000ms, and if not, the system continues to wait for the user to set the password; if yes, the system judges that the user password setting is finished;
(9) when the setting is wrong, the user can return to an initial setting interface through shaking the mobile phone, and at the moment, the system gives a long vibration prompt of 1-2 seconds, namely a failure prompt.
Secondly, a multi-touch unlocking method comprises the following steps:
(1) the terminal is in a screen locking state, a user lights a screen, an interface is divided into four areas, namely a, b, c and d, and each area is used as a touch area which is separated from each other;
(2) the system judges whether the user touches the screen for the first time, if not, the system waits for the user to start touching, and the system judges whether the waiting time exceeds the dormancy time, if so, the screen is extinguished, and the initial interface is recovered; if not, continuing to wait for the user to start to touch;
(3) the system judges whether the user touches the screen for the first time, if so, the timing of the first password is started;
(4) when the user touches the screen for the first time and inputs the first password, the system considers that the user starts to input the password and takes the password as a single-point touch;
(5) at the moment, the system judges whether the user triggers the second touch within 200ms in the four areas, if so, the system sets the first password as a multi-point touch; judging whether the user triggers the third touch within 200ms in the four areas again until the user triggers 4 times of touches when the password is input, and automatically switching the system to input the next password; if not, the system automatically changes to input the next password;
(6) the user inputs a second-bit password and a third-bit password in the same way;
(7) when the setting is wrong, the user can return to an initial setting interface through shaking the mobile phone, and the system gives a long vibration prompt of 1-2 seconds, namely a failure prompt;
(8) the system judges whether the screen is touched by the user for the last time and is greater than or equal to 5000ms, and if not, the system continues to wait for the user to input the password; if so, the system judges that the password input of the user is finished, compares whether the data is consistent with data preset by the user, if not, the unlocking is failed, gives 1-2 seconds of vibration to prompt the user that the unlocking is failed, and turns off a screen, and the system returns to an initial state; if yes, unlocking successfully, giving a correct prompt tone and entering a standby interface.
Through the specific embodiment, the unlocking mode of combining the multi-point touch with the touch times and the areas is realized by combining different composition modes and area settings through the click times of the multi-point touch. This kind of mode is applicable to blind crowd, and the variety of combination mode is greater than general password far away for the scratch through the screen can't simply be cracked with the mode of permutation and combination, and factor of safety further can improve, and increased the interest of unblock. Based on the general security menu in the setting menu, only a new mode needs to be added on the unlocking mode. The user setting can be simple, complex and diverse, and the deeper the combination level, the higher the safety.
Compared with the prior art, the invention has the beneficial effects that:
(1) the safety factor is greatly improved, and the risk of cracking through screen scratches or permutation and combination is avoided;
(2) on the basis of taking both practicability and safety into consideration, the interestingness is increased, and more users can use the toy;
(3) traditional numbers and characters are too boring, and the unlocking mode is more similar to Morse code and novel;
(4) the upper limit is not set for the combination level, and the deeper the level is, the higher the security is.
Certainly, in the above embodiment, the four areas a, b, c, and d on the touch screen may also be divided into two, six, and the like, mainly because the four areas are easier to distinguish and rich in arrangement and combination; the invention mainly uses a click mode to unlock, and any mode similar to sliding and long-time pressing can be considered as the same as the invention.
The embodiments of the present invention have been described in detail, but the embodiments are merely examples, and the present invention is not limited to the embodiments described above. Any equivalent modifications and substitutions to those skilled in the art are also within the scope of the present invention. Accordingly, equivalent changes and modifications made without departing from the spirit and scope of the present invention should be covered by the present invention.
