Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to enable a user to determine corresponding different control commands by controlling different pressures generated during pressing, the embodiment of the invention designs an information input method, which is characterized in that the magnetic induction intensity in a deformation space of an information input device is correspondingly changed in response to deformation generated by pressing operation of the user on the information input device; calculating a pressing pressure value according to the variable quantity of the magnetic induction intensity; and generating a corresponding control command according to the pressure value.
The following describes in detail an embodiment of an information input device according to an embodiment of the present invention with reference to the accompanying drawings.
An embodiment of the present invention provides an information input device, as shown in fig. 1, including: a cover layer 100, a fingerprint detection chip 110, a metal layer 120, a magnetic field generation circuit 130, a reinforcing layer 140, a sensor 150 and a processor 160.
In the embodiment of the present invention, the cover layer 100 is located on the outer layer of the information input device and covers the fingerprint detection chip 110. Alternatively, the material of the surface cover layer 100 may be tempered glass, or sapphire, or ceramic.
The cover layer 100 is used for transmitting the generated pressure to the fingerprint identification chip 110 and the metal layer 120 and deforming the metal layer 120 when a user presses the information input device.
In addition, the surface cover layer 100 has the functions of bearing, decorating and protecting, and meanwhile, optionally, the surface cover layer 100 and the information input device can be integrated, namely, no gap exists between the surface cover layer 100 and the information input device, so that the information input device is ensured to realize the function of information input under the condition of surface integration, in one implementation mode, the information input device is a key of a mobile phone, the problem that the original physical key needs to be opened in a key area is avoided, and the dustproof and waterproof performance of the information input device is improved.
Of course, the cover layer 100 is not necessarily required to be installed, and the information input device may be arranged without the cover layer, with the metal layer 120 directly disposed on the top.
In the embodiment of the present invention, the fingerprint detection chip 110 is located below the cover layer 100, covers the metal layer 120, and is connected to the processor 160.
The fingerprint detection chip 110 is used for detecting fingerprint information and transmitting the fingerprint information to the processor 160.
When the user sets fingerprint authentication, the fingerprint detection chip 110 acquires fingerprint information of the user and transmits the fingerprint information to the processor 160. The processor 160 then matches the acquired fingerprint information with the pre-configured fingerprints in the local fingerprint collection based on the local fingerprint collection to determine whether the received fingerprint information passes the fingerprint authentication. Then, when it is determined that the fingerprint information matches the preset fingerprint information, the processor 160 controls the magnetic field generation circuit 130 to generate a magnetic field.
In another embodiment, fingerprint information input by a user is acquired, whether the fingerprint information matches preset fingerprint information is judged, and if so, a corresponding control command is generated, for example, the control command may be a command for allowing payment, allowing login, allowing unlocking, and the like.
Further, the fingerprint detection chip 110 also has a function of detecting a touch screen signal and transmits the touch screen signal to the processor 160. The processor 160 may determine whether the user makes contact with the information input device according to the touch screen signal, thereby determining a control command corresponding to the user's touch screen setting.
For example, the information input device returns to the main interface of the terminal upon determining the user touch.
Of course, the fingerprint detection chip 110 is not necessarily mounted, and when the fingerprint authentication method is not used but another authentication method is used, the information input device may not be provided with the fingerprint detection chip 110.
In the embodiment of the present invention, optionally, in the information input device, a metal ring may be further disposed on the peripheries of the surface cover layer 100 and the fingerprint detection chip 110, where the metal ring is used to detect whether the user touches the surface cover layer 100, or the metal ring may not be disposed.
In the embodiment of the present invention, the metal layer 120 covers the magnetic field generating circuit 130, and optionally, in the information input device, if the fingerprint detecting chip 110 is not disposed, the metal layer 120 may be a layer of specially disposed thin metal, and if the fingerprint detecting chip 110 is disposed, the metal layer 120 may be a layer of specially disposed thin metal, or may be a part of the fingerprint detecting chip 110, for example, a reinforcing steel sheet in the fingerprint detecting chip 110, where the reinforcing steel sheet is a metal steel sheet below the flexible circuit board for reinforcing the strength of the circuit board.
The metal layer 120 is used for receiving the pressure transmitted by the cover layer 100 and the fingerprint detection chip 110 when a user presses the cover layer 100, and generates corresponding deformation based on the pressure. A hollow spacer is disposed between the metal layer 120 and the magnetic field generating circuit 130, and the hollow region of the spacer is a space for the metal layer to deform. When the metal layer 120 senses the pressure, it may be deformed in the space based on the pressure, so that a distance between the metal layer 120 and the magnetic field generating circuit 130 may be changed.
For example, referring to fig. 2, there is a space for the metal layer to deform between the metal layer 120 and the magnetic field generation circuit 130, and when the metal layer 120 receives a pressure of a user's press, deformation is generated in the space based on the pressure, thereby reducing a distance between the metal layer 120 and the magnetic field generation circuit 130.
The magnetic field generating circuit 130 may generate a magnetic field by an ac current, and when the metal layer 120 senses the magnetic field, an eddy current may be generated on the surface of the metal layer 120. In practice, when a conductor is placed in a changing magnetic field or moves relative to the magnetic field, because the conductor can form a closed loop inside, when the magnetic flux passing through the closed loop changes, a corresponding induced current is generated in the conductor, and the induced current is called an eddy current.
Further, the metal layer 120 generates an interference magnetic field opposite to the magnetic field generated by the magnetic field generating circuit 130 based on the generated eddy current, and when the metal layer 120 deforms, the distance between the metal layer 120 and the magnetic field generating circuit 130 changes, so that the interference magnetic field of the metal layer 120 affects the magnetic induction intensity of the magnetic field generating circuit 130.
In the embodiment of the present invention, the magnetic induction intensity of the magnetic field generating circuit 130 changes, so that the voltages at two ends of the magnetic field generating circuit 130 change, and further, the magnetic field generating circuit 130 converts the voltages into corresponding frequencies.
Specifically, the magnetic field generating circuit 130 may generate a magnetic field through an alternating current, and then the metal layer 120 generates a corresponding eddy current, where the alternating current and the eddy current generated by the metal layer 120 are equal in magnitude and opposite in direction, and a mutual inductance may be generated between the alternating current and the metal layer 120, and when the magnitude of the alternating current is fixed, the smaller the distance between the metal layer 120 and the magnetic field generating circuit 130 is (i.e., the larger the pressure sensed by the metal layer 120 is), the larger the mutual inductance between the alternating current and the eddy current is, and accordingly, the smaller the self-inductance of the magnetic field generating circuit 130 is, so that the voltage across the magnetic field generating circuit 130 is also smaller, and the frequency converted based on the voltage is.
In the embodiment of the present invention, the reinforcing layer 140 is located below the magnetic field generating circuit 130, and is used for supporting and preventing the magnetic field generating circuit 130 from being deformed.
Alternatively, the reinforcing layer 140 may be a main structure of the information input device, such as a rear cover of the terminal, or a middle frame of the terminal, or may be a specially configured reinforcing plate, of course, the reinforcing layer 140 is not necessarily installed, and when it is not necessary to prevent deformation and support a control command, the reinforcing layer 140 may not be provided in the information input device.
In the embodiment of the present invention, the sensor 150 is connected to the magnetic field generating circuit 130 to obtain the frequency generated by the magnetic field generating circuit 130, and then convert the frequency into a pressure value, and further connected to the processor 160 to output the pressure value to the processor 160.
In the embodiment of the present invention, the processor 160 generates the corresponding control command according to the pressure value, and may adopt, but is not limited to, the following several manners:
the first mode is as follows: the information input device establishes a first incidence relation between the pressure value and the pressure grade in advance, acquires the first incidence relation between the pressure value and the pressure grade after receiving the pressure value sent by the sensor 150, determines the pressure grade set corresponding to the pressure value based on the first incidence relation, then acquires a second incidence relation between the pressure grade and the control command, and generates the control command corresponding to the pressure grade based on the second incidence relation.
For example, the processor 160 divides the pressure value into four levels in advance, and when the pressure value > is 5N and the pressure value <10N, the corresponding pressure level is the first level; a second level when the pressure value > <10N and the pressure value < 20N; a third level when the pressure value > <20N and the pressure value < 50N; when the pressure value > is 50N, it is the fourth level.
The processor 160 receives the pressure value 10N sent by the sensor 150, determines the corresponding pressure level as a second level based on the first association relationship, and then generates a "pause" control command corresponding to the second level based on the second association relationship.
Further, in order to enable the user to accurately determine the corresponding control command through the pressure value of the pressing operation, when the user performs the pressing operation, and when the pressure value reaches the threshold value preset corresponding to each pressure level, optionally, the user may be notified of the currently reached pressure level through the number of vibrations or through the corresponding audio frequency, so as to enable the user to determine the corresponding control command.
By adopting the first mode, the user can enable the information input device to generate a corresponding control command by changing the size of the pressure value for pressing the information input device, so that corresponding operation is executed, the operation steps of the user are simplified, the time is saved, and convenience is brought to the user.
The second way is: the processor 160 obtains the pressing times of the pressing operation within the preset time and a third correlation between the pressing times and the control command, and generates the control command corresponding to the pressing times based on the third correlation.
For example, if the processor 160 obtains that the number of pressing times of the pressing operation within the preset time 5s is 4, the "replay" control command corresponding to the number of pressing times of 4 is generated based on the third correlation.
By adopting the second mode, the user can control the pressing times of the pressing operation on the information input device within the preset time to enable the information input device to generate a corresponding control command, so that the corresponding operation is executed, the time is saved, the efficiency is improved, and the convenience is brought to the user.
The third mode is as follows: the processor 160 obtains the duration of the pressing operation and a fourth association relationship between the duration and the control command, and generates the control command corresponding to the duration based on the fourth association relationship.
For example, if the duration of the user pressing is 5s, the processor 160 generates a "run" control command corresponding to 5s based on the fourth association relationship.
By adopting the third mode, the user can control the duration of the pressing operation on the information input device to enable the information input device to generate a corresponding control command, so that corresponding operation is executed, the operation steps are simplified, the efficiency is improved, and convenience is provided for the user.
The fourth mode is as follows: the information input device establishes a first association relationship between the pressure value and the pressure grade in advance, acquires the first association relationship between the pressure value and the pressure grade after receiving the pressure value sent by the sensor 150, determines the pressure grade set corresponding to the pressure value based on the first association relationship, then acquires the duration of the pressure grade, and then the processor 160 acquires a fifth association relationship among the pressure grade, the duration and the control command, and generates the control command corresponding to the pressure grade and the duration based on the fifth association relationship.
For example, a fifth relationship among the pressure level, the duration and the control command, which is pre-established by the processor 160, is: the control command set corresponding to the first grade and the first preset time length 2s is a 'photographing' control command; the control command set corresponding to the second grade and the second preset time length 3s is an audio playing control command; the control command set corresponding to the third grade and the third preset time length 4s is an audio playing control command; the control command set corresponding to the fourth level and the preset duration 5s is a "pause" control command.
When the processor 160 determines that the duration time with the pressure level as the second level reaches 3s, the control command set corresponding to the pressure level and the duration time is determined to be the "audio playing" control command based on the fifth association relationship, and the "audio playing" control command is generated.
By adopting the fourth mode, the user can enable the information input device to generate a corresponding control command by controlling the combination of the pressure grade corresponding to the pressure value of the pressing operation of the information input device and the duration of the pressing operation, so that the corresponding control command can be executed.
The fifth mode is as follows: the information input device establishes a first association relationship between a pressure value and a pressure grade in advance, acquires the first association relationship between the pressure value and the pressure grade after receiving the pressure value sent by the sensor 150, determines the pressure grade set corresponding to the pressure value based on the first association relationship, then the processor 160 acquires the pressing frequency of the pressing operation within a preset time period, then the processor 160 acquires a sixth association relationship among the pressure grade, the pressing frequency and a control command, and generates the control command corresponding to the pressure grade and the pressing frequency based on the sixth association relationship.
For example, the preset time period set by the processor 160 is 1s, and the user presses the information input device a plurality of times within 1 s. The processor 160 determines that the pressing frequency with the second level is 2, and then the processor 160 obtains a sixth association relationship among the pressure level, the pressing frequency and the control command, and generates a "fast forward" control command corresponding to the second level and the pressing frequency 2 based on the sixth association relationship.
By adopting the fifth mode, the user can control the combination of the pressure grade and the pressing frequency corresponding to the pressure value of the pressing operation on the information input device within the preset time to enable the information input device to generate the corresponding control command, so that the corresponding control command can be executed.
Thus, the information input device can generate a corresponding control command according to one or a combination of the pressure value of the pressing operation, the duration of the pressing operation and the pressing frequency of the pressing operation when the user presses the information input device.
In the embodiment of the invention, after the information processing device determines the control command set corresponding to the pressure value, the duration or the pressing times, the information processing device directly executes the control command set corresponding to the pressure value.
In the embodiment of the present invention, optionally, the information input device may be formed as a key, and the shape of the key may be circular, elliptical, or oval.
In the embodiment of the present invention, the information input device may adopt, but is not limited to, the following operation modes:
fingerprint scanning mode: when the fingerprint detection chip 110 is provided, the information input device recognizes a fingerprint through the fingerprint detection chip 110.
Standby fingerprint identification mode: when the fingerprint detection chip 110 is provided and the information input device is in a standby state, the information input device implements a touch screen detection function, a fingerprint identification function, and a wake-up processor function through the fingerprint detection chip 110.
And (3) key mode: the information input device detects the pressure value through the magnetic field generating circuit 130 and the sensor 150, and determines and executes a control command corresponding to the pressure value, such as a HOME key, through the processor 160.
A sleep mode: when the fingerprint detection chip 110 is provided and the information input device is in a low power consumption state, the processor 160 may wake up the fingerprint detection chip 110 and the sensor 150 through the pins.
The following describes a specific procedure of information input in detail by using a specific embodiment, and the present invention is not limited to the following embodiment.
In practical application, after a user presses the information input device, the information input device obtains pressure generated when the user presses the information input device, forms a magnetic field and an interference magnetic field based on corresponding deformation generated by the pressure, generates corresponding voltage based on the magnetic field and the interference magnetic field, and converts the voltage into corresponding frequency.
Then, the information input device converts the frequency into a pressure value, and determines a pressure level set corresponding to the pressure value based on the acquired first correlation between the pressure value and the pressure level. Meanwhile, the information input device determines the control command set corresponding to the pressure grade through the second incidence relation between the acquired pressure grade and the control command.
Optionally, after the user presses, when the information input device reaches the threshold corresponding to each preset pressure level based on the pressure value, the information input device may feed back to the user through vibration or audio frequency, so that the user determines the control command set corresponding to the pressure.
For example, after the user presses the information input device, when the information input device determines that the pressure level corresponding to the acquired pressure value reaches the second level, the user is notified that the pressure level reached under the pressure is the second level through two consecutive vibrations. Further, the user determines that the control command corresponding to the second level setting is a "bluetooth on" control command.
Further, the information processing apparatus directly executes the control command corresponding to the pressure value setting after determining the control command corresponding to the pressure value setting.
By adopting the mode, after the control command corresponding to the pressure value setting is determined, the corresponding control command is directly executed, so that the method has higher efficiency and saves time.
In the embodiment of the invention, the magnetic induction intensity in the deformation space of the information input device is correspondingly changed in response to the deformation generated by the pressing operation of a user on the information input device; calculating a pressing pressure value according to the variable quantity of the magnetic induction intensity; and generating a corresponding control command according to the pressure value. Like this, information input device alright through the different pressure when response user presses, for the user provides corresponding different control command, and the user only need press a point alright trigger multiple control command through the finger, and need not open the menu and constantly click the selection to simplified user's operating procedure, saved operating time, improved operating efficiency, and then effectively promoted user experience.
