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 implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a volume adjustment method according to an exemplary embodiment, where the volume adjustment method is applied to a terminal having a touch screen, as shown in fig. 1, and includes the following steps.
In step S11, a touch signal is obtained by a first sensor, and it is detected whether a touch position of the touch signal is within a target area of the touch screen.
In step S12, an action type signal corresponding to the touch signal is obtained through a second sensor, and it is detected whether the action type corresponding to the touch signal is a click type.
In step S13, when it is determined that the touch position of the touch signal is within the target area of the touch screen and the action type corresponding to the touch signal is the click type, it is determined that the touch signal is a volume adjustment signal.
In step S14, the volume of the terminal is adjusted according to the volume adjustment signal.
The terminal in the present disclosure may be a smartphone, a smart watch, a smart bracelet, a tablet computer, or the like. The terminal includes a touch screen, and in step S11, a first sensor acquires a touch signal and detects whether a touch position of the touch signal is within a target area of the touch screen. Wherein the first sensor may be a capacitive sensor; when a user touches the screen with a finger, the capacitance change value of the screen is obtained through the capacitance sensor, and then the generated touch signal can be obtained. The first sensor may be a pressure sensor; when a user touches the screen with a finger, the pressure change value of the screen is obtained through the capacitive sensor, and then the generated touch signal can be obtained.
And after the touch signal is acquired, detecting whether the touch position of the touch signal is in the target area of the touch screen. Taking a capacitive touch screen as an example, when a finger touches the screen, due to an electric field of a human body, a coupling capacitor is formed between a user and the surface of the touch screen, for a high-frequency current, the capacitor is a direct conductor, so that the finger draws a small current from a contact point, the current respectively flows out from electrodes on four corners of the touch screen, the current flowing through the four electrodes is in direct proportion to the distances from the finger to the four corners, a touch position of the touch point, namely an (x, y) coordinate, is obtained through accurate calculation of the proportion of the four currents, and whether the touch position is in the target area is determined according to the (x, y) coordinate.
As shown in fig. 1, the steps S12 and S11 have no sequential execution order, and after acquiring the touch signal, the steps S11 and S12 may be performed simultaneously. In step S12, the action type signal corresponding to the touch signal may be detected by a second sensor, for example, when the user clicks the terminal with a finger, a displacement, a speed, an acceleration, or a pressure applied to the touch screen of the terminal may change, and may be detected by the corresponding second sensor (e.g., a displacement sensor, a speed sensor, an acceleration sensor, or a pressure sensor). Since the user may consider the touch signal to be a volume adjustment signal due to a fact that the finger or a part of the skin of the human body is in the target area of the terminal due to a misoperation in the process of using the touch screen, for example, the finger slides into the target area when sliding on the touch screen, the disclosure may exclude the misoperation of the user by adding the step S12 of detecting whether the action type corresponding to the touch signal is a click type, thereby improving the accuracy of volume adjustment.
As shown in fig. 1, when the detection result of the step S11 is that the touch position is within the target area and the detection result of the step S12 is that the action type corresponding to the touch signal is the click type, the step S13 is executed to determine that the touch signal is a volume adjustment signal.
After determining that the touch signal is a volume adjustment signal, executing step S14, and adjusting the volume of the terminal according to the volume adjustment signal. When the touch position is detected not to be in the target area or the touch operation is not the click operation, no operation may be performed.
Optionally, the target area may include a first target area and a second target area, and the adjusting the volume of the terminal according to the volume adjustment signal may include: when the touch position is in the first target area, increasing the volume of the terminal; and when the touch position is in the second target area, reducing the volume of the terminal. When the touch position is in the first target area, the touch signal is a volume adjusting signal for increasing the volume in the terminal; and when the touch position is in the second target area, the touch signal is a volume adjusting signal for reducing the volume in the terminal.
For example, as shown in fig. 2, a first target area 211 and a second target area 212 are provided on the touch screen 21 of the terminal 20, where the first target area 211 represents a volume-up position and the second target area 212 represents a volume-down position. If the resolution of the display screen of the terminal 20 is 1440 × 2560, the top coordinate position of the first target area 211 is (1439, 220), and the bottom coordinate position is (1439, 370), the touch operation of the click type with the x coordinate of 1439 and the y coordinate ranging from 220 to 370 may be recognized as the volume adjustment signal for increasing the volume. Similarly, assuming that the top coordinate position of the second target area 212 is (1439, 480) and the bottom coordinate position is (1439, 630), the click-type touch operation with the x coordinate of 1439 and the y coordinate ranging from 480 to 630 can be recognized as the volume adjustment signal for reducing the volume.
Optionally, the degree of the volume adjustment signal for adjusting the volume of the terminal is directly proportional to the number of clicks of the clicking operation. For example, once the touch screen is clicked, the volume of the terminal is increased by one grid; and clicking the touch screen three times, and turning up the volume of the terminal for three grids.
According to the method, the target area is arranged on the terminal touch screen, in order to adjust the volume of the terminal, whether the touch position of the touch signal is in the target area or not is detected, and whether the action type corresponding to the touch signal is a click type or not is detected, so that the condition of misoperation of a user can be eliminated, the accuracy of volume adjustment is improved, the click operation of the target area is similar to the click of an entity volume key in the related technology, namely the entity volume key is replaced by the touch operation, and the problem that the entity volume key becomes the obstruction of the design of an ultrathin terminal is solved.
Fig. 3 is another flow chart illustrating a method of volume adjustment according to an example embodiment. As shown in fig. 3, the volume adjusting method is applied to a terminal having a touch screen and may include the following steps.
In step S31, a touch signal is obtained by a first sensor, and it is detected whether a touch position of the touch signal is within a target area of the touch screen.
In step S32, an action type signal corresponding to the touch signal is obtained through a second sensor, and it is detected whether the action type corresponding to the touch signal is a click type.
In step S33, a first time when a touch signal is acquired by the first sensor is recorded.
In step S34, a second time at which the second sensor acquires the motion type signal is recorded.
In step S35, when it is determined that the time difference between the first time and the second time is smaller than the first set threshold, it is determined that the motion type signal acquired by the second sensor is the motion type signal corresponding to the touch signal acquired by the first sensor.
In step S36, when it is determined that the touch position of the touch signal is within the target area of the touch screen and the action type corresponding to the touch signal is the click type, it is determined that the touch signal is a volume adjustment signal.
In step S37, the volume of the terminal is adjusted according to the volume adjustment signal.
Since the acquisition of the touch signal and the acquisition of the motion type signal are performed by two different sensors, in order to avoid the problem that the time of events reported by the two sensors (where the first sensor reports the acquired touch signal and the second sensor reports the acquired motion type signal) is inconsistent and the problem that the motion type signal acquired by the second sensor does not correspond to the touch signal acquired by the first sensor, a first time window is set, the width of the first time window is the first set threshold, and the first set threshold may be 10ms or 8ms, which is not limited in this disclosure.
When the first sensor acquires a touch signal, recording the touch signal as a first moment; when the second sensor acquires the action type signal, recording the action type signal as a second moment; and if the time difference between the first time and the second time is within a first time window (namely, smaller than the first set threshold), determining that the action type signal acquired by the second sensor is the action type signal corresponding to the touch signal acquired by the first sensor. When the time difference between the first time and the second time is not within the first time window (i.e. is greater than the first set threshold), the adjustment signal may be considered to be invalid, and is a faulty action, and may not be operated.
By recording the first moment when the touch signal is acquired by the first sensor and the second moment when the action type signal is acquired by the second sensor, when the time difference between the two moments is detected to be smaller than a first set threshold value, the action type signal acquired by the second sensor can be determined to be the action type signal corresponding to the touch signal acquired by the first sensor, so that the accuracy of volume adjustment is further improved, and the situation that the volume of the terminal is adjusted by a user due to misoperation is avoided.
Fig. 4 is another flow chart illustrating a method of volume adjustment according to an example embodiment. As shown in fig. 4, the volume adjusting method is applied to a terminal having a touch screen, and may include the following steps.
In step S41, a touch signal is obtained by a first sensor, and it is detected whether a touch position of the touch signal is within a target area of the touch screen.
In step S42, an action type signal corresponding to the touch signal is obtained through a second sensor, and it is detected whether the action type corresponding to the touch signal is a click type.
In step S43, a third time when the touch position of the touch signal is determined to be within the target area of the touch screen is recorded.
In step S44, a fourth time when the action type corresponding to the touch signal is determined to be the click type is recorded.
In step S45, when it is determined that the time difference between the third time and the fourth time is smaller than a second set threshold, it is determined that the touch signal is a volume adjustment signal.
In step S46, the volume of the terminal is adjusted according to the volume adjustment signal.
Although the detection of whether the touch position is in the target area and the detection of whether the action type corresponding to the touch signal is the click type are both completed in the framework layer, the two detections are correspondingly performed by two different CPUs, in order to avoid the problem that the times of two CPUs reporting events (one of which reports that the touch position is in the target area and the other reports that the action type corresponding to the touch signal is the click type) are inconsistent, a second time window is set, the width of the second time window is the second set threshold, and the second set threshold may be 20ms or 15ms, for which, the disclosure is not particularly limited.
When one CPU detects that the touch position is in the target area, recording as a third moment; when the other CPU detects that the action type corresponding to the touch signal is the fourth moment of the click type, recording the action type as the fourth moment; and if the time difference between the third moment and the fourth moment is within a second time window (namely, less than a second set threshold), the touch signal is a volume adjusting signal, and the volume of the terminal is adjusted according to the volume adjusting signal. When the time difference between the third time and the fourth time is not within a second time window (i.e. greater than a second set threshold), the adjustment signal may be considered to be invalid, and is a behavior of misoperation, and may not be operated.
And when the time difference is detected to be smaller than a second set threshold, the volume of the terminal is adjusted according to the volume adjusting signal, so that the accuracy of volume adjustment is further improved, and the situation that the volume of the terminal is adjusted due to misoperation of a user is avoided.
The method comprises the steps that a user clicks a target area of a touch screen and the user mistakenly operates the target area of the touch screen, so that the accelerated speed generated by a terminal is obviously different, for example, the terminal slides into the target area of the touch screen when sliding on the touch screen, and the accelerated speed generated by the terminal is obviously smaller than the accelerated speed generated by clicking the touch screen, and therefore, whether the touch operation is the click operation can be confirmed by detecting the accelerated speed of the terminal.
Optionally, the terminal is provided with an acceleration sensor, and the obtaining of the action type signal corresponding to the touch signal by the second sensor includes: acquiring an acceleration signal corresponding to the touch signal through an acceleration sensor; the determining that the action type corresponding to the touch signal is a click type includes: and when the acceleration characteristic corresponding to the acceleration signal is determined to be matched with the acceleration characteristic corresponding to the clicking action, determining that the action type corresponding to the touch signal is the clicking type.
Since the operation type corresponding to the acceleration signal needs to be determined according to the waveform characteristics of the signal, the fourth time in step S44 in fig. 4 may be later than the third time in step S43.
Wherein the determining that the acceleration feature corresponding to the acceleration signal matches the acceleration feature corresponding to the clicking action comprises: determining that the waveform characteristics of the acceleration signal meet a preset condition, wherein the waveform characteristics at least comprise two of a wave peak value, a wave valley value, a change time from a starting point to a wave peak value and a time from the wave peak to a wave valley. The preset condition may be that at least two of a peak value, a valley value, a change time from a starting point to the peak value, and a time from the peak value to the valley are within a corresponding preset value range, for example, the peak value of the acceleration signal is greater than a first preset value, the valley value of the acceleration signal is greater than a second preset value, the change time from the starting point to the peak value of the acceleration signal is less than a third preset value, and the time from the peak value to the valley of the acceleration signal is less than a fourth preset value.
The acceleration sensor can detect acceleration signals in three different directions of an x axis, a y axis and a z axis, the present disclosure can detect whether an acceleration feature corresponding to the acceleration signal of the terminal in one direction of the three different directions of the x axis, the y axis and the z axis matches with an acceleration feature corresponding to a click action through the acceleration sensor, and when the acceleration sensor detects that the acceleration feature corresponding to the acceleration signal of the terminal in one direction matches with the acceleration feature corresponding to the click action, the action type corresponding to the touch signal is a click type.
Optionally, when it is detected by the acceleration sensor that an acceleration feature corresponding to an acceleration signal of the terminal in the x-axis direction matches an acceleration feature corresponding to a click action, the action type corresponding to the touch signal is a click type. Referring to fig. 5 and 6, fig. 5 is a graph illustrating x-axis data output by an acceleration sensor when a terminal is at rest according to an exemplary embodiment, and fig. 6 is a graph illustrating x-axis data output by an acceleration sensor when a terminal is clicked according to an exemplary embodiment. In fig. 5 and 6, the abscissa is time in units of ms; the ordinate is the displacement in the x-axis direction in mm.
As shown in fig. 5, when the terminal is held stationary, the x-axis data of the acceleration sensor is substantially 0. Fig. 6 is x-axis data output by the acceleration sensor when the user double-clicks the touch screen. As shown in FIG. 6, it can be seen that a single click corresponds to a regular waveform, with the peaks of the two waveforms in FIG. 6 being around 2mm and the troughs being around-3 mm. Namely, the terminal is clicked to enable the acceleration signal generated by the terminal to be greatly different from the static state of the terminal, so that whether the acceleration characteristic corresponding to the acceleration signal of the terminal is matched with the acceleration characteristic corresponding to the click action or not can be detected through the acceleration sensor, and the action type corresponding to the touch signal is confirmed to be the click type.
For example, whether the wave peak value of the acceleration signal in the x-axis direction is greater than 1.5mm, whether the wave trough value of the acceleration signal is greater than 2mm, whether the change time from the start point of the acceleration signal to the wave peak value (i.e., the time from the x-axis to the wave peak) is less than 5ms, and whether the time from the wave peak of the acceleration signal to the wave trough of the acceleration signal is less than 3ms may be detected to confirm that the action type corresponding to the touch signal is the click type. Assuming that a wave peak value of the acceleration signal in the x-axis direction is greater than 1.5mm, a wave trough value is greater than 2mm, a change time from a starting point to a wave peak value (i.e., a time from the x-axis to the wave peak) is less than 5ms, and a time from the wave peak to the wave trough is less than 3ms, it may be determined that the action type corresponding to the touch signal is a click type.
Whether the action type corresponding to the touch signal is the click type or not is determined by detecting whether the acceleration characteristic corresponding to the acceleration signal of the terminal is matched with the acceleration characteristic corresponding to the click action, so that the condition of misoperation of a user can be eliminated, and the accuracy of volume adjustment is improved; and when the touch position is in the target area and the acceleration characteristic corresponding to the acceleration signal of the terminal is matched with the acceleration characteristic corresponding to the clicking action, adjusting the volume of the terminal according to the volume adjusting signal so as to replace the volume adjustment of the entity volume key to the terminal.
Fig. 7 is a block diagram illustrating a volume adjustment device according to an exemplary embodiment. Referring to fig. 7, the volume adjusting apparatus 700 is applied to a terminal having a touch screen, and the volume adjusting apparatus 700 includes a first detecting module 710, a second detecting module 720, a first determining module 730, and an adjusting module 740.
