Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Currently, there are some solutions to the misdialed call, and some typical solutions are described in detail below.
The Chinese patent with the application number of 200910106305.X, the invention name of which is a mobile phone system for preventing mistaken call dialing and a method thereof provides a method for preventing mistaken call dialing, which comprises the following steps: calling through; reading a voice data value, and judging whether the voice comes from normal speaking voice of a person or not through a speech detection process; and determining whether to keep the call connected according to the call sending detection result. However, in implementing this scheme, it is necessary to detect whether there is a normal voice in the voice of the call after the call is made, so as to prevent the call from being made without any wave, but since this scheme is a scheme for preventing the call from being made by mistake, it should be operated before the call is made, so this scheme does not really prevent the call from being made by mistake.
The chinese patent application with application number 201410145829.0, entitled method and apparatus for preventing misdialing, provides a method for preventing misdialing, which comprises: receiving a call-out instruction; judging whether the call-out instruction belongs to misdialing or not according to the dialing process before the call-out instruction is received and a preset rule base; if the call is a wrong call, executing specified operation; and if the calling is not the wrong calling, executing the call calling instruction. The process of the current dialing is compared with a prefabricated rule base in the scheme, part of judgment rules are shown in fig. 1, the scheme can play a certain role in preventing the wrong dialing, but the habit that a user uses a mobile phone to dial a telephone is greatly different, although the rules in the rule base can be adjusted along with the use of the user, when the user just starts to use the mobile phone, the rules in the rule base can be default rules when the mobile phone leaves a factory, the wrong dialing function cannot be effectively prevented, or the normal operation of the user can be identified as the wrong dialing, so that the user cannot normally broadcast the telephone, and the problem of wrong judgment can be caused.
The chinese patent application with application number 201510707290.8, entitled method for preventing telephone misdialing and mobile terminal, provides a method for preventing telephone misdialing and mobile terminal, comprising: when a dialing instruction is received, detecting whether the mobile terminal is located in a dialing interface currently, wherein the dialing interface is used for a user to trigger dialing operation; and if the mobile terminal is positioned on the dialing interface, captures the face of the user and an area touched by the finger of the user exists on the dialing interface, carrying out dialing operation according to the dialing instruction. The scheme limits the detection of the wrong dialing to the dialing interface, and considers that in many cases, a user dials in non-dialing interfaces such as an address list and the like, so that the method cannot be applied to all scenes.
The Chinese patent application with the application number of 201510925968.X and the name of the invention of preventing the method for the wrong dialing provides a method for preventing the wrong dialing, which comprises the following steps: displaying a starting interface; displaying a preset area; detecting whether an operation instruction is received in a preset area, and if so, acquiring a fingerprint; detecting whether the size of the fingerprint is larger than a preset size, if so, starting dialing, otherwise, setting a confirmation area in the preset area, detecting whether the confirmation area receives a confirmation instruction, if so, starting dialing, and otherwise, exiting the preset area. However, in this embodiment, hardware devices are required to support fingerprint detection, but there are fewer terminals with fingerprint detection function, so that the method is not suitable for all terminals.
The chinese patent application with the application number of 201510456143.8, entitled method for preventing misdialing and terminal provides a method for preventing misdialing, which comprises: receiving input dialing operation; responding to the dialing operation, and acquiring the biological characteristic information of a user executing the dialing operation; matching the biological characteristic information with preset biological characteristic information, wherein the preset biological characteristic information is used for representing illegal dialing users; and judging whether the biological characteristic information is consistent with the preset biological characteristic information or not, if so, prohibiting the call from being dialed, and if not, dialing the call. The implementation of the scheme requires hardware equipment to support the detection of the biological characteristic signal, but the terminals with the detection function of the biological characteristic signal are fewer, so the method cannot be applied to all terminals.
The chinese patent application with the application number of 201410091141.9 entitled mobile terminal and method for preventing misdialing thereof provides a mobile terminal and method for preventing misdialing thereof. The method is based on a mobile terminal comprising a distance sensor and a touch display screen, when the touch display screen is not locked and a dial icon is displayed, the distance sensor is started to detect whether a shelter exists in an effective distance above the touch display screen; if yes, the distance sensor detects to obtain the current distance between the shielding object and the touch display screen of the mobile terminal; and when the current distance is smaller than the preset critical distance threshold, the mobile terminal controls the touch display screen not to display the dial icon and closes the distance sensor. Because the scheme is based on the distance sensor on the mobile phone, the distance sensor is generally positioned on two sides of the mobile phone receiver or in the groove of the mobile phone receiver, the distance sensing is realized by emitting infrared light, when an object approaches, the returned infrared light can be detected by the element, the approach distance of the object can be judged, and the distance sensing is generally used for automatically closing a screen after the phone is switched on. However, the distance sensor is easily interfered by noise, the precision of the distance sensor on the mobile phone is limited, the values acquired by the distance sensors of different mobile phone manufacturers are greatly different, and the problem of misjudgment is caused by adopting a threshold value comparison method.
From the above description, it can be seen that the present solutions all have certain drawbacks, mainly expressed in the following aspects:
1. a specific use scene is needed, such as a call must be made on a dialing interface, the call needs to be made first, and the like;
2. hardware devices with special functions, such as fingerprint identification, biological characteristic signal detection, and the like, are required;
3. it is necessary to restrict the use habits of the user.
Secondly, the situation that a terminal such as a mobile phone with a touch screen makes a wrong call is that a user puts the mobile phone into a pocket or a bag without locking the screen after using the mobile phone, other objects touch the screen of the mobile phone in the moving process such as walking and the like, a dialing function is triggered at a certain probability, and then the situation that the wrong call is made occurs. Therefore, by carefully observing the occurrence of the wrong call, the following characteristics are provided when the wrong call occurs:
1. when the wrong dialing occurs, the screen of the mobile phone is not locked;
2. interfaces where misdialing occurs are diversified, and interfaces where a call can be dialed in the mobile phone include a dialing interface, a contact interface, a short message interface, a call record interface, a third-party dialing software interface and the like;
3. the time when the misdialing occurs is random;
4. the process by which the mispronunciations occur is random.
Meanwhile, careful consideration is given to the following common points when a call is normally made:
1. the calling is actively carried out by the user, and the mobile phone attracts all attention of the user or is one of focuses of the attention of the user;
2. when a call is made, a contact person needs to be found, so that a user can face a mobile phone screen;
in addition, in view of the popularization of smart phones at present, the smart phones of both low end and high end have the following hardware configurations: light sensor, leading camera, acceleration sensor (gravity-feed tank).
Therefore, the sensors (the light sensor, the front camera and the acceleration sensor) commonly existing on the intelligent terminals can be used for detecting the false dialing prevention through ambient light, portrait and mobile phone posture detection, so that the false dialing prevention detection which is not limited by a dialing interface, special hardware and user habits is realized, has high precision and can be generally applicable.
Based on this, in various embodiments of the invention: receiving a dialing instruction; the dialing instruction is used for triggering and acquiring relevant information of the environment where the terminal is located and attitude information of the terminal; acquiring light intensity information of the environment where the terminal is located; acquiring image information of the environment where the terminal is located at the moment when the dialing instruction occurs; acquiring attitude information of the terminal; and calling out control processing is carried out on the dialing instruction by utilizing the light intensity information, the image information and the posture information.
Example one
The dialing control method of the embodiment of the invention, as shown in fig. 2, includes the following steps:
step 201: receiving a dialing instruction;
here, the dialing instruction is used to trigger obtaining of relevant information of an environment where the terminal is located and attitude information of the terminal.
Step 202: acquiring light intensity information of the environment where the terminal is located; acquiring image information of the environment where the terminal is located at the moment when the dialing instruction occurs; acquiring attitude information of the terminal;
here, in practical applications, the light intensity information may be obtained by a light sensor disposed on the terminal. The image information can be collected through a camera arranged on the terminal, and the attitude information can be collected through an acceleration sensor arranged on the terminal.
Step 203: and calling out control processing is carried out on the dialing instruction by utilizing the light intensity information, the image information and the posture information.
Specifically, whether the terminal is in a screen locking state is detected;
and when the terminal is in a non-screen-locking state, calling control processing is carried out on the dialing instruction by using the light intensity information, the image information and the posture information.
And when the terminal is in a screen locking state, terminating the dialing process.
Here, when the terminal is in a screen locking state, a dialing instruction is received, which means that the dialing instruction is automatically sent by a background program, the terminal is likely to be remotely controlled, the dialing instruction is generated under the condition that a user does not know, and a dialing process needs to be stopped at the moment so as to avoid causing bad influence to the user, causing embarrassment and even misunderstanding of the user, and the like.
In practical application, the call control processing is performed on the dialing instruction, and specifically, the call control processing may be: and executing the dialing instruction, starting dialing, or terminating the dialing process.
More specifically, when it is determined that the dialing operation corresponding to the dialing instruction is not an operation that the user mistakenly dials, using the light intensity information, the image information, and the posture information, the call control processing on the dialing instruction is: executing the dialing instruction and starting dialing; when the light intensity information, the image information and the posture information are used for determining that the dialing operation corresponding to the dialing instruction is the operation of mistakenly dialing by a user, the calling control processing of the dialing instruction is as follows: the dialing process is terminated.
When the terminal is in the screen unlocking state and the dialing process is terminated, the user is indicated that the terminal is placed in a pocket or a bag when the user uses the terminal to unlock the screen, other objects stick out the screen of the terminal in the moving process, and therefore the dialing function is triggered, and at the moment, the terminal is controlled to be in the screen unlocking state, so that the situation of mistaken dialing is avoided.
In practical application, the specific implementation of this step may include:
extracting a feature graph from the image information based on a preset graph feature extraction strategy by using the image information; carrying out portrait recognition processing by using the characteristic graph to obtain a first value; the first value represents the probability that the image information contains the portrait;
the attitude information is X, Y, Z axis acceleration information; determining a second value using the acceleration information; the second value characterizes an amount of upward motion of the terminal from a first time to a second time; the first moment is the moment when the dialing instruction occurs; the second moment is the current moment;
determining a fourth value using the first, second, and third values; the third value is an output value of the light sensor reflecting the light intensity information; the fourth value is the probability that the call corresponding to the dialing instruction is misdialed;
and carrying out calling control processing on the dialing instruction by using the fourth value.
Wherein, the determining the second value by using the acceleration information specifically includes:
determining a fifth value by using the Z-axis acceleration information at the first moment and the second moment; the fifth value characterizes a direction of motion of the terminal;
determining a sixth value by using the first time X, Y, Z and the second time X, Y, Z axle acceleration information; the sixth value is indicative of an amount of motion resulting from the motion of the terminal from the first time instant to the second time instant;
and determining a second value by using the fifth value and the sixth value.
Here, the specific process of determining the second value using the acceleration information is formulated as follows:
wherein the content of the first and second substances,
respectively showing acceleration information of X-axis, Y-axis and Z-axis at the first time, Xt、yt、ztAcceleration information on the X-axis, Y-axis, and Z-axis at the second time is displayed,
represents a fifth value;
represents a sixth value; ε is a constant.
Here, in practical application, epsilon may be calculated using regression using a large number of experiments, or may be set empirically.
Determining a fourth value using the first value, the second value, and the third value, including:
determining a seventh value using the first value and the third value; the seventh value represents a probability that the image information contains a portrait under a corresponding environment;
determining an eighth value using the second value and the third value; the eighth value is indicative of an amount of upward movement of the terminal under a corresponding environment;
and summing the seventh value and the eighth value to obtain the fourth value.
Here, the process of determining the fourth value, expressed by the formula, is:
f(l,p,t0,t)＝αlp+(T-l)ψ(t0,t) (2)
wherein l represents the output value of the light sensor, i.e. a third value, and the larger l is, the stronger the brightness of the ambient light is; p represents a first value, and the larger p indicates that the image contains a portraitThe higher the probability; psi (t)0T) denotes an amount of upward movement of the terminal from the first time to the second time, i.e. a second value, ψ (t)0The larger t) is, the higher the probability that the terminal moves vertically upwards is; alpha and T are constants; α lp represents a seventh value, which can be understood as a probability that the image information contains a portrait in a bright environment; (T-l) ψ (T)0And t) represents an eighth value, which can be understood as the amount of upward movement from the first time to the second time terminal in a non-bright environment.
Here, in actual application, α and T may be obtained by regression calculation using a large number of experiments, or may be set empirically.
In order to improve the universality of the anti-misdialing, after the fourth value is obtained, the dialing instruction may be subjected to call control processing by using some set rules and the fourth value, for example: under the condition that the terminal is determined to be misdialed, terminating the dialing process and locking the screen of the terminal; when the dialing is possible to be mistaken or normal, a dialog box is popped up to ensure that the user confirms.
Based on this, in an embodiment, the performing, by using the fourth value, outgoing call control processing on the dialing instruction may specifically include:
when the fourth value is less than or equal to a first threshold value, terminating the dialing process;
alternatively, the first and second electrodes may be,
when the fourth value is larger than the first threshold value and smaller than or equal to the second threshold value, sending out prompt information; the prompt information is used for prompting a user whether to start dialing aiming at the dialing instruction; when the first operation is not received within the preset time period, terminating the dialing process; the first operation is a response operation to the prompt message;
alternatively, the first and second electrodes may be,
and when the fourth value is larger than the second threshold value, executing the dialing instruction and starting dialing.
Wherein the first threshold is less than a second threshold. In practical application, the first threshold value and the second threshold value are set according to requirements.
And when the fourth value is smaller than or equal to the first threshold value, the dialing operation corresponding to the dialing instruction is a misdialing operation, a dialing process needs to be terminated, and the terminal can be further controlled to be in a screen locking state. When the fourth value is greater than the first threshold and less than or equal to the second threshold, it is indicated that the dialing operation corresponding to the dialing instruction may be a wrong dialing operation or a non-wrong dialing operation, and at this time, a prompt message needs to be sent to the user, that is, the user is allowed to confirm by popping up a dialog box, so as to further identify whether the dialing operation corresponding to the dialing instruction is the wrong dialing operation or the non-wrong dialing operation; when the first operation is not received within the preset time period, the dialing operation corresponding to the dialing instruction is further explained as a misdialing operation, a dialing process needs to be terminated, and the terminal can be further controlled to be in a screen locking state.
Here, when the first operation is received within a preset time period and the first operation is a confirmation operation for starting dialing for the dialing instruction, the dialing instruction is executed and dialing is started.
And when the first operation is received within a preset time period and the first operation is a cancelling operation for starting dialing aiming at the dialing instruction, terminating the dialing process.
The dialing control method provided by the embodiment of the invention receives a dialing instruction; the dialing instruction is used for triggering and acquiring relevant information of the environment where the terminal is located and attitude information of the terminal; acquiring light intensity information of the environment where the terminal is located; acquiring image information of the environment where the terminal is located at the moment when the dialing instruction occurs; acquiring attitude information of the terminal; the dialing instruction is called out and controlled by utilizing the light intensity information, the image information and the attitude information, and the dialing instruction is called out and controlled by utilizing the ambient light of the terminal, the image information of the environment and the attitude information of the terminal, so that the dialing instruction is not limited by the use habit of a user, and the detection precision of the mistaken dialing can be effectively improved. Meanwhile, the ambient light, the image information of the environment and the attitude information of the terminal can be acquired by utilizing a sensor and a camera which are commonly used on the terminal, and hardware equipment with special functions is not required to be additionally arranged on the terminal, so that the scheme of the embodiment of the invention is convenient to implement and easy to realize.
In addition, when the terminal is in the screen unlocking state and the dialing process is terminated, the terminal is controlled to be in the screen locking state, so that the problem of mistaken dialing once more can be effectively solved, the power consumption of the terminal is reduced, and the user experience is improved.
In addition, when the fourth value is larger than the first threshold value and smaller than or equal to the second threshold value, sending out prompt information; the prompt information is used for prompting a user whether to start dialing aiming at the dialing instruction; when the first operation is not received within the preset time period, terminating the dialing process; the first operation is a response operation to the prompt message, and when the dialing operation corresponding to the dialing instruction cannot be accurately identified as a wrong dialing operation or a non-wrong dialing operation (normal dialing operation), the first operation is combined with the operation of a user to further identify whether the dialing operation corresponding to the instruction is the wrong dialing operation or the non-wrong dialing operation, so that the detection precision of the wrong dialing call can be further improved.
When the terminal is in the lock screen state, terminate the dialing process, so, avoided being by remote control when the terminal, the mistake that produces under the condition that the user is not aware of is dialled the operation, has eliminated to have this to bring not good influence for the user, lets the user fall into embarrassment, causes the misconnection etc. even, has further promoted user experience.

When the terminal is in the screen unlocking state and the dialing process is terminated, it indicates that the user puts the terminal into a pocket or a bag when using the terminal to unlock the screen, and other objects stick out the screen of the terminal in the moving process, so as to trigger the dialing function, and at this time, the control unit 33 controls the terminal to be in the screen unlocking state, so as to avoid the situation of mistaken dialing.
In practical applications, the control unit 33 is specifically configured to:
extracting a feature graph from the image information based on a preset graph feature extraction strategy by using the image information; carrying out portrait recognition processing by using the characteristic graph to obtain a first value; the first value represents the probability that the image information contains the portrait;
the attitude information is X, Y, Z axis acceleration information; determining a second value using the acceleration information; the second value characterizes an amount of upward motion of the terminal from a first time to a second time; the first moment is the moment when the dialing instruction occurs; the second moment is the current moment;
determining a fourth value using the first, second, and third values; the third value is an output value of the light sensor reflecting the light intensity information; the fourth value is the probability that the call corresponding to the dialing instruction is misdialed;
and carrying out calling control processing on the dialing instruction by using the fourth value.
Wherein, the determining the second value by using the acceleration information specifically includes:
the control unit 33 determines a fifth value by using the Z-axis acceleration information at the first time and the second time; the fifth value characterizes a direction of motion of the terminal;
the control unit 33 determines a sixth value using the first time point and the second time point X, Y, Z axis acceleration information; the sixth value is indicative of an amount of motion resulting from the motion of the terminal from the first time instant to the second time instant;
the control unit 33 determines a second value using the fifth value and the sixth value.
Here, the specific process of determining the second value using the acceleration information is formulated as follows:
wherein the content of the first and second substances,
respectively showing acceleration information of X-axis, Y-axis and Z-axis at the first time, Xt、yt、ztAcceleration information on the X-axis, Y-axis, and Z-axis at the second time is displayed,
represents a fifth value;
represents a sixth value; ε is a constant.
Here, in practical application, epsilon may be calculated using regression using a large number of experiments, or may be set empirically.
Determining a fourth value using the first value, the second value, and the third value, including:
the control unit 33 determines a seventh value using the first value and the third value; the seventh value represents a probability that the image information contains a portrait under a corresponding environment;
the control unit 33 determines an eighth value using the second value and the third value; the eighth value is indicative of an amount of upward movement of the terminal under a corresponding environment;
the control unit 33 sums the seventh value and the eighth value to obtain the fourth value.
Here, the process of determining the fourth value, expressed by the formula, is:
f(l,p,t0,t)＝αlp+(T-l)ψ(t0,t) (2)
wherein l represents the output value of the light sensor, i.e. a third value, and the larger l is, the stronger the brightness of the ambient light is; p represents a first value, and the larger p is, the higher the probability of containing the portrait in the image is; psi (t)0T) denotes an amount of upward movement of the terminal from the first time to the second time, i.e. a second value, ψ (t)0The larger t) is, the higher the probability that the terminal moves vertically upwards is; alpha and T are constants; α lp represents a seventh value, which can be understood as a probability that the image information contains a portrait in a bright environment; (T-l) ψ (T)0And t) represents an eighth value, which can be understood as the amount of upward movement from the first time to the second time terminal in a non-bright environment.
Here, in actual application, α and T may be obtained by regression calculation using a large number of experiments, or may be set empirically.
In order to improve the universality of the anti-misdialing, after the fourth value is obtained, the dialing instruction may be subjected to call control processing by using some set rules and the fourth value, for example: under the condition that the terminal is determined to be misdialed, terminating the dialing process and locking the screen of the terminal; in the case of either a mis-dial or a normal dial, the control unit 33 pops up a dialog box for the user to confirm.
Based on this, in an embodiment, the performing, by using the fourth value, outgoing call control processing on the dialing instruction may specifically include:
when the fourth value is equal to or less than the first threshold value, the control unit 33 terminates the dialing process;
alternatively, the first and second electrodes may be,
when the fourth value is greater than the first threshold value and less than or equal to the second threshold value, the control unit 33 sends a prompt message; the prompt information is used for prompting a user whether to start dialing aiming at the dialing instruction; when the first operation is not received within a preset time period, the control unit 33 terminates the dialing process; the first operation is a response operation to the prompt message;
alternatively, the first and second electrodes may be,
when the fourth value is greater than the second threshold, the control unit 33 executes the dialing instruction to start dialing.
Wherein the first threshold is less than a second threshold. In practical application, the first threshold value and the second threshold value are set according to requirements.
When the fourth value is less than or equal to the first threshold, it indicates that the dialing operation corresponding to the dialing instruction is a misdialing operation, and the dialing process needs to be terminated, and the control unit 33 may further control the terminal to be in a screen locking state. When the fourth value is greater than the first threshold and is less than or equal to the second threshold, it indicates that the dialing operation corresponding to the dialing instruction may be a wrong dialing operation or a non-wrong dialing operation, and at this time, the control unit 33 needs to send a prompt message to the user, that is, the user is allowed to confirm by popping up a dialog box, so as to further identify whether the dialing operation corresponding to the dialing instruction is a wrong dialing operation or a non-wrong dialing operation; when the first operation is not received within the preset time period, it is further described that the dialing operation corresponding to the dialing instruction is a misdialing operation, the control unit 33 needs to terminate the dialing process, and may further control the terminal to be in a screen locking state.
Here, when the first operation is received within a preset time period and the first operation is a confirmation operation to start dialing for the dialing instruction, the control unit 33 executes the dialing instruction to start dialing.
When the first operation is received within a preset time period and the first operation is a cancel operation of starting dialing for the dialing instruction, the control unit 33 terminates the dialing process.
In practical application, the dialing instruction obtaining unit 31 and the control unit 33 may be implemented by a processor in a dialing control device; the acquisition unit 32 can be implemented by an acquisition device (including a sensor, a camera, etc.) in the dial control device.
In the dialing control apparatus provided in the embodiment of the present invention, the dialing instruction obtaining unit 31 receives a dialing instruction; the dialing instruction is used for triggering and acquiring relevant information of the environment where the terminal is located and attitude information of the terminal; the acquisition unit 32 acquires light intensity information of the environment where the terminal is located; acquiring image information of the environment where the terminal is located at the moment when the dialing instruction occurs; acquiring attitude information of the terminal; the control unit 33 performs call control processing on the dialing command by using the light intensity information, the image information, and the posture information, and performs call control processing on the dialing command by using the ambient light of the terminal, the image information of the environment, and the posture information of the terminal, without being limited by the use habit of the user, so that the detection accuracy of the mistaken call can be effectively improved. Meanwhile, the ambient light, the image information of the environment and the attitude information of the terminal can be acquired by utilizing a sensor and a camera which are commonly used on the terminal, and hardware equipment with special functions is not required to be additionally arranged on the terminal, so that the scheme of the embodiment of the invention is convenient to implement and easy to realize.
In addition, when the terminal is in a screen unlocking state and the dialing process is terminated, the control unit 33 controls the terminal to be in a screen locking state, so that the problem of mistaken dialing once again can be effectively avoided, the power consumption of the terminal is reduced, and the user experience is improved.
In addition, when the fourth value is greater than the first threshold value and is equal to or less than the second threshold value, the control unit 33 issues a prompt message; the prompt information is used for prompting a user whether to start dialing aiming at the dialing instruction; when the first operation is not received within a preset time period, the control unit 33 terminates the dialing process; the first operation is a response operation to the prompt message, and when the dialing operation corresponding to the dialing instruction cannot be accurately identified as a wrong dialing operation or a non-wrong dialing operation (normal dialing operation), the first operation is combined with the operation of a user to further identify whether the dialing operation corresponding to the instruction is the wrong dialing operation or the non-wrong dialing operation, so that the detection precision of the wrong dialing call can be further improved.
