Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Currently, it is a trend to reduce or even eliminate the number of open solid keys on the mobile device, i.e. the terminal, which interact with the outside world. This requires that the operations performed by these physical keys be integrated into the functional modules under the touch panel of the mobile device.
The present disclosure provides a method and apparatus for integrating functions of physical keys on a terminal onto a touch panel. The pressure sensor under the touch panel senses the pressure applied to the touch panel, and if the pressure reaches a set value, the touch panel is determined to be pressed by the finger of a user. Then, based on the power-on or power-off state of the terminal and the condition that the user presses the touch panel, the terminal operations, such as power-on, power-off, unlocking, volume control and song playing control, are executed.
In an embodiment, fig. 1 exemplarily shows a schematic structural diagram of a terminal, where the terminal is, for example, a full-screen mobile phone, the mobile phone has no physical keys around the mobile phone, and a touch panel of the terminal is displayed on the top. In the terminal of the present disclosure, a pressure sensor is provided under the touch panel. Wherein the pressure sensor comprises a capacitor for sensing pressure, the pressure sensor being powered by the terminal battery and the pressure sensor being powered by the battery as long as the battery is charged, even when the terminal is shut down. In addition, heart rate and blood oxygen sensors can be integrated under the touch panel, so that the response signals of blood in blood vessels on the fingers to light signals are collected by utilizing an optical principle, and the heart rate and blood oxygen of an operator are determined by analyzing the response signals.
The pressure sensor shown in fig. 2 is disposed under the touch panel of the mobile phone shown in fig. 1, where a and b are two electrode plates of a capacitor for sensing pressure, c and d are both signal lines, E is an elastic layer, F is a cavity, and G is a silicon substrate. And a fingerprint identification sensor is arranged below the touch panel and used for detecting fingerprints.
By adopting the structure of the mobile phone, the pressure of the fingers is sensed by the pressure sensor arranged below the touch panel, so that terminal operations including machine operation, shutdown operation, unlocking operation, volume control and song playing control, health state detection and the like are executed. These terminal operations need not be executed by physical keys, and only the touch panel needs to be operated.
The terminal can be a mobile phone, a PAD, a wearable device and other intelligent terminals.
Fig. 3 is a flowchart illustrating a control method of a terminal including a touch panel according to an exemplary embodiment, as shown in fig. 3, including the steps of:
and step 303, executing terminal operation based on at least one of the working state, the duration and the change of the pressed position.
In step 301, when it is sensed that the touch panel is pressed and the pressure of the touch panel reaches the set pressure threshold, the working state of the terminal is obtained because the terminal may be pressed by surrounding objects when being placed in a backpack or a pocket of clothes, and this does not indicate that the user wants to operate the terminal. The pressure threshold here can be set according to the actual need.
In step 302, the change in the pressed position refers to a linear distance between the start position and the end position of the pressing.
When it is determined that the user wants to operate the terminal, the operating state of the terminal, the duration of time the touch panel is pressed, and the change in the pressed position are acquired, and the operation of the terminal is performed based on the above-mentioned factors. Here, the operation of the terminal includes power on, power off, screen unlocking, play volume control, and play track control. The specific mode of operation will be described in detail below.
In the method shown in fig. 3, the pressure to which the touch panel is subjected is sensed through the touch panel, and a terminal operation is performed based on the operating state of the terminal, the pressing duration and the change of the pressing position, so that the function of a physical key on the terminal is realized through the operation on the touch panel. The design reduces open holes on the terminal shell, optimizes the appearance of the terminal, enhances the antistatic capacity of the terminal, integrates the functions of information interaction and information entry on the touch panel of the terminal, and enhances the functions of the existing interaction and information entry.
In an optional embodiment, the operating state at least includes turning on and off the screen, and turning off the screen.
In an alternative embodiment, said performing terminal operations based on at least one of said operating state, said duration and said change in pressed position comprises at least:
in case one, when the working state is shutdown and the pressed duration reaches a first time threshold, executing the terminal startup operation;
in case two, when the working state is the screen on/off state, the pressed duration reaches a second time threshold, and the change of the pressed position is smaller than a distance threshold, executing the terminal shutdown operation;
in case III, when the working state is starting up and screen off and the change of the pressed position is smaller than the distance threshold, executing the unlocking operation of the terminal screen;
and fourthly, when the working state is that the screen is turned on or turned off when the terminal is turned on, and the change of the pressed position is larger than or equal to the distance threshold, executing the terminal volume control operation or the switching operation of the playing content.
Several cases are enumerated herein in which the operation of the terminal is performed based on the operating state of the terminal, the duration of the pressing, and the change in the pressed position. The first time threshold refers to the duration time required by the finger to press when the power-on operation is determined, and the second time threshold refers to the duration time required by the finger to press when the power-off operation is determined. The first time threshold and the second time threshold may be the same or different, and specific values may be set according to actual needs. The distance threshold can also be set according to practical needs, for example 0.5cm or 1 cm.
When the operating state is the power-on screen-on or the power-on screen-off state and the duration of the pressing reaches the second time threshold, the volume or the track that the user wants to control the application playing through the touch panel may also be, and therefore in case two, the condition determined as the power-off operation further includes: the change in the pressed position is less than the distance threshold.
Similarly, in case three, the condition determined as the screen unlock operation includes, in addition to the operating state being power on and off, the following: the change of the pressed position is smaller than a distance threshold value so as to distinguish the operation of controlling the volume or the track played by the application from the screen unlocking operation.
In the fourth case, the volume of the terminal can be controlled or the playing content can be switched no matter in the working state of turning on or turning off the screen.
In an optional embodiment, the executing the terminal screen unlocking operation includes at least one of the following modes:
in a first mode, in a state of starting and turning off a screen, a set area on the touch panel is displayed or flickered at set brightness, fingerprint information is obtained in the set area, and when authentication is successful based on the fingerprint information, the terminal screen is unlocked;
and in the second mode, in the state of starting and turning off the screen, the fingerprint information is acquired on the touch panel, and when authentication based on the fingerprint information is successful, the terminal screen is unlocked.
When the screen unlocking operation is executed in the working state of starting and turning off the screen, a user is required to input a fingerprint for authentication, and a set area on the touch panel can be flickered or highlighted so as to indicate the user to press the input fingerprint in the set area to realize unlocking; the user may press the input fingerprint on any area of the touch panel to unlock without specifying an area. The setting area in the first mode may be a position where a home key stored by the terminal is located when the screen is turned off. If the entire touch panel is provided with the layer of fingerprint recognition sensor, as in the second mode, the specific area on the touch panel is not designated, and the user can obtain fingerprint information to unlock the touch panel by pressing any area on the touch panel.
In an optional implementation manner, the performing of the terminal volume control operation or the switching operation of the play content includes:
detecting a displacement of the pressed position;
and executing the terminal volume control operation or the switching operation of the playing content based on the displacement change of the pressed position.
A start position and an end position of the finger pressing on the display screen can be acquired. The variation in the displacement of the pressing position can be obtained by the starting position and the end position. Based on the displacement change, the volume of the terminal can be adjusted to be increased or decreased, or the content played by the terminal (including played audio, video and pictures) can be switched to be the previous or next one.
In one embodiment, controlling the volume of the terminal based on a displacement change of the pressed position includes:
acquiring an abscissa change value or an ordinate change value of the displacement change of the pressed position on a plane rectangular coordinate system corresponding to the display screen, and controlling the volume of the terminal based on the abscissa change value or the ordinate change value.
In another embodiment, switching the content played by the terminal based on the displacement change of the pressing position includes:
and acquiring an abscissa change value or an ordinate change value of the displacement change of the pressed position on a plane rectangular coordinate system corresponding to the display screen, and switching the contents played by the terminal based on the abscissa change value or the ordinate change value.
In this embodiment, the terminal volume control operation or the switching operation of the played content is performed by sliding a finger on the touch panel. The concrete description is as follows:
and corresponding the pressed position on the touch panel to the plane rectangular coordinate system corresponding to the touch panel, namely, each pressed position on the touch panel corresponds to one coordinate (x, y) in the plane rectangular coordinate system. The change in the pressed position is a change value on the abscissa and a change value on the ordinate, which correspond to the start position and the end position of the pressing, respectively. For example, the starting position A of the pressingnHas the coordinates of (x)n,yn) End of pressingEnd position An+1Has the coordinates of (x)n+1,yn+1) As shown in fig. 4, where n is a positive integer, the variation value of the abscissa and the variation value of the ordinate are Δ x ═ x, respectivelyn+1-xnAnd Δ y ═ yn+1-yn。
The playing volume or the playing track may be controlled based on the abscissa variation value or the ordinate variation value, for example, the playing volume may be controlled based on the abscissa variation value, and the playing track may be controlled based on the ordinate variation value. When delta x is larger than 0, the volume is controlled to be increased, and when delta x is smaller than 0, the volume is controlled to be decreased; when delta y is greater than 0, the next song is controlled to be played, and when delta y is less than 0, the previous song is controlled to be played.
In addition, the linear distance between the two positions can be calculated based on the coordinates of the start position and the coordinates of the end position, and a specific calculation formula is not described herein again.
It should be noted that, when the terminal is playing rich media, the playing volume of the media is controlled; and when the terminal is not playing the sound, controlling the system volume of the terminal.
By adopting the method, the volume of the terminal or the played content can be controlled by pressing the display screen with fingers and sliding on the display screen. Such operations on the screen may replace operations on physical keys. The control mode is particularly suitable for the full-screen mobile phone without entity keys, which is researched by various mobile phone manufacturers at present.
In an optional embodiment, when it is detected that the touch panel is pressed, the method further includes:
acquiring a display state of the terminal;
when the display state of the terminal is a desktop display state, acquiring a body health index of a user through a health detection module under a touch panel of the terminal; or
And when the display state of the terminal is a screen locking state, after screen unlocking operation is executed, acquiring a body health index of a user through the health detection module under the touch panel of the terminal.
Specifically, the user physical health index may be obtained by:
emitting an optical signal to the pressed position;
acquiring a response signal of blood to the optical signal;
and acquiring a body health index of the user based on the response signal.
The physical fitness index acquired in this embodiment may be a heart rate index and a blood oxygen index. The health detection module is arranged below the touch panel and comprises a heart rate sensor and a blood oxygen sensor, holes can be drilled in the display screen, response signals of blood in blood vessels on the fingers to light signals are collected by using the small-hole imaging principle, and the heart rate and the blood oxygen of an operator are determined by analyzing the response signals.
By adopting the method, the function of detecting the health state can be integrated in the terminal which is almost carried about by people, so that the user can conveniently detect the health state at any time and in real time.
Specifically, the heart rate and blood oxygen sensor is provided with a light emitting device and a light receiving device. When the light emitting device emits infrared light or visible light to the fingerprint, the emitted light signal penetrates the skin deep into the capillaries due to the abundance of capillaries in the finger, the light signal and the blood components generate a spectral response signal reflecting the absorption characteristics of the blood for the spectrum, and thus the heart rate and the blood oxygen components are detected by the spectrum in the response signal received by the light receiving device. The optical receiving device can detect the spectral components in the optical detection channels through RGBC and other optical detection channels, realize the detection of blood oxygen according to the spectral characteristics of hemoglobin carrying oxygen to the optical band, and realize the heart rate detection according to the wave crests and the wave troughs of the received response signals. The specific principles for determining heart rate and blood oxygen from the response signal are known to the person skilled in the art and will not be described in further detail herein.
When the mobile phone is used for detecting the health state, the user may press the mobile phone screen in a desktop display state or may press the mobile phone screen in a screen locking state. It should be noted that, the detection of the health status belongs to a relatively private operation, and therefore, the operation can be performed only after the mobile phone is unlocked. When the mobile phone is in a screen locking state, screen unlocking operation is required, and after the screen is unlocked, the health index of the user is obtained through the health detection module.
In an alternative embodiment, the method further comprises:
arranging a pressure sensor under the touch panel, wherein the pressure sensor comprises a capacitor for sensing pressure;
supplying power to the pressure sensor in the working states of turning on and turning off the screen or turning off the screen;
and determining whether the touch panel is pressed or not by detecting whether the capacitance value of the capacitor changes or not.
The description of detecting whether the touch panel is pressed by the pressure sensor is specifically as follows.
When a finger presses the screen, whether a pressing signal exists is determined by detecting the change of capacitance between the electrode plates in the pressure sensor. The pressure sensor is provided with a polar plate a and a polar plate b, the pressing causes the polar plate b to generate displacement delta d, the change delta C of the capacity between the polar plate a and the polar plate b is caused, and the pressing signal is detected when the delta C is detected.
When the static state is set, the distance between the polar plate a and the polar plate b is d0The capacitance between two polar plates is C0(ii) a The pressing causes the displacement of the polar plate b to be delta d, so that the capacitance change caused by the displacement is delta C, and the total capacitance between the two polar plates is C. Let the vacuum dielectric constant be epsilon0The dielectric constant between the plate a and the plate b is epsilonrAnd if the area of the opposite surfaces of the polar plate a and the polar plate b is S, the formula (1) is obtained. Capacitor C with two polar plates when not pressed0As shown in formula (2), the capacitance value change caused by pressing is shown in formula (3), and the capacitance change rate caused by pressing is obtained by dividing formula (3) by formula (2), thereby obtaining formula (4).
And (5) solving the capacitance change according to the formula (4). The change in the displacement of the pad b due to the pressing is relatively small, i.e., as shown in equation (6), then the change in the displacement of the pad b due to the pressing is divided by d0The value of (d) goes to 0, giving equation (7). As a result of equation (7), equation (8) results; due to equation (8), then a public is obtainedFormula (9).
By combining the formula (4) and the formula (9), the formula (10) is obtained, and then Δ C is obtained, so that Δ C is linearly related to the displacement change caused by pressing, and whether the touch panel is pressed or not can be determined based on the displacement change.
limΔd∝0 (6)
It should be noted that in the power-off state or the power-on and screen-off state, the screen backlight is in the power-off state, and in the power-off state or the power-on and screen-on state, the device for collecting fingerprints and authenticating may be in the power-off state.
