Background technique

With the rapid development of science and technology, more and more touch products appear in our daily life, such as smart phones, digital cameras, car touch screens, etc. These touch products can use the different pressure generated by pressing the touch screen to form different Visual effects that give users the feeling of interacting with touch products. For example, when a passenger rides a vehicle, he/she presses a finger on the vehicle touch screen to select a corresponding function, and the vehicle touch screen can form ripples with different visual effects at the pressed position of the passenger's finger.

At present, the most common pressure detection method based on the touch screen is generally to set a pressure sensor under the touch screen to detect the change of the pressure, and then form different visual effects according to the change of the pressure.

Example 1

Please refer to FIG. 2 , which is a schematic flowchart of a touch screen-based pressure detection method disclosed in an embodiment of the present invention. As shown in Figure 2, the method may include the following steps.

201. When detecting that the user's finger presses the touch screen, the pressure detection apparatus monitors the target number of the capacitive sensors that are triggered among the plurality of capacitive sensors.

In this embodiment of the present invention, the touch screen includes a plurality of capacitive sensors. When the user's finger presses on the touch screen, the capacitive sensor at the position is triggered, indicating that the position on the touch screen is pressed.

In the embodiment of the present invention, the above-mentioned touch screen may be applied to a smart phone, a digital camera, and a smart car, which is not limited in the embodiment of the present invention. For ease of understanding, the embodiment of the present invention is described by taking a smart car as an example. In the embodiment of the present invention, a touch screen is applied to a smart car, that is, a vehicle-mounted touch screen. When a passenger presses on the touch screen with a finger, the pressure detection device can monitor in real time. The target number of capacitive sensors that are triggered among the multiple capacitive sensors included in the touch screen.

202. The pressure detection device detects whether the target quantity remains unchanged within a preset time; if yes, execute step 203; if not, continue to execute step 202.

In the embodiment of the present invention, it can be understood that when the user's finger just presses the touch screen, because the user's finger just begins to deform slightly, the area that touches the touch screen is very small at first, and the first capacitive sensor is just triggered at this time. 7 is an example diagram of a pressure detection operation disclosed in an embodiment of the present invention. As shown in FIG. 7 , the small square zebra grid is a capacitive sensor. When the user's finger just presses the touch screen, capacitive sensor 0 is triggered. When the user's finger continues to press the touch screen, the pressure of the user's finger on the touch screen gradually increases, the user's finger begins to deform slowly, the area touching the touch screen gradually increases, and the triggered capacitive sensor gradually increases. Please refer to FIG. 8 is an example diagram of another pressure detection operation disclosed by an embodiment of the present invention. As shown in FIG. 8 , the small square zebra grid is a capacitive sensor. The user's finger continues to press the touch screen, and the area touching the touch screen gradually changes. Large, multiple capacitive sensors such as capacitive sensor 1 to capacitive sensor 8 are triggered. When the pressure of the user's finger pressing the touch screen remains unchanged, the user's finger stops deforming, the area touching the touch screen remains unchanged, and the triggered capacitive sensor also remains unchanged. When the pressure detection device detects the number of targets of the triggered capacitive sensor When it remains unchanged within the preset time, step 203 is executed.

In the embodiment of the present invention, the preset time may be set by a tester through a large number of experiments, which is not limited in the embodiment of the present invention.

203. The pressure detection device determines the contact area between the user's finger and the touch screen according to the number of targets.

In the embodiment of the present invention, it can be understood that, since the area represented by a single capacitive sensor can be known, when the pressure detection device detects that the target number of the capacitive sensors triggered remains unchanged for a preset time, it indicates the pressure with which the user's finger presses the touch screen. No longer changes, at this time, the pressure detection device can determine the contact area between the user's finger and the touch screen according to the target number of triggered capacitive sensors, that is, the product of the area represented by a single capacitive sensor and the target number of triggered capacitive sensors.

204. The pressure detection device acquires, according to the contact area, a pressure value of the user's finger pressing the touch screen.

In the embodiment of the present invention, it can be considered that the pressure on the touch screen is a constant, and the constant can be measured in advance. Therefore, the pressure detection device can calculate the pressure value of the user's finger pressing the touch screen according to the contact area between the user's finger and the touch screen, Specifically, as shown in the following formula (1):

p=F/S (1)

Among them, p is the pressure that the touch screen bears, F is the pressure value of the user's finger pressing the touch screen, and S is the contact area between the user's finger and the touch screen.

As an optional implementation manner, in step 204, after the pressure detection device obtains the pressure value of the user's finger pressing the touch screen according to the contact area, the following steps may also be performed:

Send a friend instruction to the service platform, so that the service platform obtains the pressure value generated by another user's finger pressing another touch screen reported by another pressure detection device, as well as obtains the identity information of the other user, and compares the other pressure value with the pressure value. The identity information of the other user is returned to the stress detection device; wherein the other stress detection device is a stress detection device included in the in-vehicle central control system of another vehicle, and the identity information of the other user includes gender, age and/or occupation;

judging whether the difference between the pressure value and another pressure value is less than a preset threshold;

If it is less than the preset threshold, obtain the user's identity information;

Generate a friendship index based on the user's identity information and another user's identity information;

When the friendship index is greater than the preset friendship index threshold, the friend recommendation information is sent to another stress detection device, so that the other stress detection device outputs the friend recommendation information to another user; wherein the friend recommendation information at least includes the user's Social account information.

Implementing this optional embodiment, when the difference between the pressure values generated by the two users pressing the touch screen is smaller than a preset threshold, a friendship index is generated according to the user's identity information and the identity information of another user, that is, the two users are evaluated. The possibility of becoming a friend, and when the friendship index is large enough, push the friend recommendation information to another pressure detection device, so that the other pressure detection device outputs the friend recommendation information to another user, which is beneficial to realize through interaction with the touch screen Make friends and improve user experience.

As an optional implementation manner, in step 204, after the pressure detection device obtains the pressure value of the user's finger pressing the touch screen according to the contact area, the following steps may also be performed:

When receiving the seat adjustment instruction input by the user, obtain the seat adjustment relationship table; the seat adjustment relationship table is used to indicate the corresponding relationship between the pressure generated by the user pressing the touch screen and the seat adjustment range;

According to the pressure value, obtain the target seat adjustment range matching the pressure value from the seat adjustment relationship table;

Adjust the seat according to the target seat adjustment range.

In this embodiment of the present invention, the seat adjustment relationship table may be a corresponding relationship between the pressure generated by the user pressing the touch screen and the seat adjustment range, which is set by the tester according to a large number of experiments and stored in the local cache, where the pressure The larger the value, the larger the adjustment range of the seat, which is not limited in the embodiment of the present invention.

By implementing this optional embodiment, when the user feels that the current posture of the seat is unsuitable, the seat can be adjusted according to the pressure value, which greatly improves the interactivity and user experience.

In the embodiment of the present invention, as an optional implementation, the pressure detection device may be provided with a voice module, which can be used to recognize an input voice command, such as a “please adjust the seat” adjustment password, and the adjustment password is used as the seat adjustment password. The adjustment command, when the adjustment password is detected, the pressure detection device acquires the seat adjustment relation table. By implementing this optional embodiment, the seat adjustment command can be input through voice, and then the seat adjustment can be performed according to the pressure value, which greatly improves the interactivity.

It can be seen that, implementing the method described in FIG. 2, according to the action principle of force, the greater the pressure of the user's finger pressing the touch screen, the greater the deformation of the user's finger, the greater the contact area between the user's finger and the touch screen, and the greater the number of triggered capacitive sensors. The pressure detection device determines the contact area between the user's finger and the touch screen according to the number of multiple capacitive sensors on the touch screen that are triggered, and then calculates the pressure value of the user's finger pressing the touch screen according to the contact area. There is no need to set up additional pressure sensors, which can reduce costs. Moreover, it overcomes the fact that the detection of the pressure by the traditional pressure sensor is easily affected by the vibration of the vehicle, and the accuracy of the pressure detection is improved.

Embodiment 2

Please refer to FIG. 3 . FIG. 3 is a schematic flowchart of another touch screen-based pressure detection method disclosed in an embodiment of the present invention. As shown in Figure 3, the method may include the following steps.

301. When detecting that the user's finger presses the touch screen, the pressure detection apparatus monitors the target number of the capacitive sensors that are triggered among the plurality of capacitive sensors.

302. The pressure detection device detects whether the target quantity remains unchanged within the preset time; if yes, execute step 303; if not, continue to execute step 302.

303. The pressure detection device divides the target area according to the distribution of the triggered capacitive sensors on the touch screen, wherein the density of the triggered capacitive sensors in the target area is greater than the preset density, and the area of the target area is greater than the first predetermined density. The set area is smaller than the second preset area.

In the embodiment of the present invention, for example, when the user accidentally presses the touch screen with multiple fingers, the pressure detection device divides multiple target areas at this time. For example, when the user presses the touch screen with three fingers, the pressure detection device can divide three target areas according to the distribution of the triggered capacitive sensors on the touch screen.

304. The pressure detection device determines whether the number of target areas exceeds the preset number; if not, execute step 305; if yes, end the process.

In this embodiment of the present invention, it can be understood that when the number of target areas exceeds the preset number, it may be considered that the user touches the touch screen by mistake. For example, when the preset number is one, when the user presses three fingers on the touch screen, the pressure detection device can divide three target areas according to the distribution of the triggered capacitive sensors on the touch screen. At this time, the number of target areas exceeds The preset number indicates that the user touches the touch screen by mistake, and the process ends.

In the embodiment of the present invention, steps 303 to 304 are implemented, the target area is divided according to the distribution of the triggered capacitive sensors on the touch screen, and it is determined whether the number of target areas exceeds the preset number. On the premise of preventing users from accidentally touching the touch screen, the efficiency of pressure detection is improved.

305. The pressure detection device acquires the first triggered target capacitive sensor among the triggered capacitive sensors.

In the embodiment of the present invention, it can be understood that when the user's finger just presses the touch screen, because the user's finger just begins to produce slight deformation, the area that touches the touch screen is very small at first, and the first capacitive sensor is just triggered at this time. Therefore, The pressure detection device can acquire the first triggered target capacitive sensor among the triggered capacitive sensors.

306. The pressure detection device obtains the first number of triggered capacitive sensors distributed on the left side of the vertical line and the triggered capacitances distributed on the right side of the vertical line based on the vertical line where the target capacitive sensor is located relative to the touch screen. The second number of sensors.

In the embodiment of the present invention, it can be understood that when the user presses the touch screen with a finger and then slides to the left, the triggered capacitive sensors distributed on the left side of the vertical line are based on the vertical line where the target capacitive sensor is located relative to the touch screen. The first number is greater than the second number of triggered capacitive sensors distributed on the right side of the vertical line; when the user presses the touch screen with a finger and then slides to the right, the target capacitive sensor is based on the vertical line where the touch screen is located, and the distribution The first number of triggered capacitive sensors on the left side of the vertical line is smaller than the second number of triggered capacitive sensors on the right side of the vertical line; when the user presses the touch screen with a finger and does not slide, the target capacitance The sensors are based on the vertical line where the touch screen is located, and the first number of triggered capacitive sensors distributed on the left side of the vertical line is approximately equal to the second number of triggered capacitive sensors distributed on the right side of the vertical line.

307. The pressure detection device determines whether the difference between the first quantity and the second quantity is smaller than the preset difference; if so, execute step 308; if not, end the process.

In the embodiment of the present invention, the preset difference value may be set by a tester according to a large number of experimental results, which is not limited in the embodiment of the present invention. In this embodiment of the present invention, when the difference between the first number and the second number is less than the preset difference, it can be considered that the target capacitive sensor is based on the vertical line where the touch screen is located, and is distributed on the left side of the vertical line. The first number of triggered capacitive sensors on the side is approximately equal to the second number of triggered capacitive sensors distributed on the right side of the vertical line, that is, the user does not slide after pressing the touch screen with a finger.

As an optional implementation manner, after the pressure detection device determines that the difference between the first quantity and the second quantity is greater than or equal to the preset difference, the following steps may also be performed:

If the first number is greater than the second number, control the currently displayed content on the touch screen to slide to the left, so that the content of the next page is displayed on the touch screen;

If the first number is less than the second number, control the currently displayed content on the touch screen to slide to the right, so that the content of the previous page is displayed on the touch screen.

In the embodiment of the present invention, for example, when the user wants the content of the next page to be displayed on the touch screen, the user can use a finger to press the touch screen and then slide to the left, so that the triggered capacitive sensors distributed on the left side of the vertical line The first number is greater than the second number of the triggered capacitive sensors distributed on the right side of the vertical line. At this time, the pressure detection device controls the current display content on the touch screen to slide to the left, so that the content of the next page is displayed on the on the touch screen. For another example, when the user wants the content of the previous page to be displayed on the touch screen, he can use his finger to press the touch screen and then slide to the right, so that the first number of triggered capacitive sensors distributed on the left side of the vertical line is less than The second number of triggered capacitive sensors distributed on the right side of the vertical line. At this time, the pressure detection device controls the current display content on the touch screen to slide to the right, so that the content of the previous page is displayed on the touch screen.

Implementing this optional implementation, if the user swipes to the left after pressing the touch screen with a finger, the content of the next page can be displayed on the touch screen; Content is displayed on the touchscreen, which greatly enhances interactivity.

308.
