Detailed ways

In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

An embodiment of the present invention provides a method for simulating sliding on a touch screen, the method comprising: mapping a dot matrix composed of N×N infrared sensors to a touch screen with M×M pixels, where both N and M are greater than 1 A natural number, and the N is not greater than the M; capture the gesture on the screen formed by the dot matrix infrared sensor; calculate the sliding distance d of the gesture on the screen formed by the dot matrix infrared sensor corresponding to the The sliding distance d' on the touch screen with M×M pixels; the distance d' in response to the sliding on the touch screen with M×M pixels. Embodiments of the present invention also provide a corresponding device for simulating sliding on a touch screen and a mobile terminal. Each will be described in detail below.

Please refer to FIG. 1 , which is the implementation flow of the method for simulating touch screen sliding provided by Embodiment 1 of the present invention, and its execution subject may be a mobile terminal such as a smart phone or a tablet computer. The method for simulating touch screen sliding illustrated in accompanying drawing 1 mainly includes the following steps S101 to S104:

S101 , mapping a dot matrix formed by N×N infrared sensors to a touch screen with M×M pixels.

In the embodiment of the present invention, both N and M are natural numbers greater than 1, and N is not greater than M. Mapping a dot matrix composed of N×N infrared sensors to a touch screen with M×M pixels is equivalent to dividing each M pixel into N equal parts, each with M/N pixels, and then, N×N In a dot matrix composed of three infrared sensors, the first infrared sensor in each column or row of dot matrix corresponds to the M/Nth pixel in the corresponding column or row of M×M pixels, and the second infrared sensor corresponds to The 2M/Nth pixel in the corresponding column or row in the M×M pixels, ..., the Nth infrared sensor corresponds to the Mth pixel in the corresponding column or row in the M×M pixels. For example, for a dot matrix composed of 50×50 infrared sensors, if it is to be mapped to a touch screen with 300×300 pixels, divide 300 into 50 equal parts, and each interval of 6 pixels is divided into 50×50 infrared sensors. One infrared sensor in the dot matrix formed by the sensor corresponds. Specifically, the first infrared sensor in each column or row of the dot matrix composed of 50×50 infrared sensors corresponds to the sixth pixel in the corresponding column or row in the 300×300 pixels, and the second The first infrared sensor corresponds to the 12th pixel in the corresponding column or row of 300×300 pixels, ..., the 50th infrared sensor corresponds to the 300th pixel in the corresponding column or row of 300×300 pixels . It should be noted that when M/N is not an integer, M/N is rounded down or rounded up depending on the situation. Once the dot matrix composed of N×N infrared sensors is mapped to the touch screen with M×M pixels, the continuous sensor (Sensor) data generated by gesture movements can be converted into continuous motion event (MotionEvent) data, which is equivalent to M Data generated by a touch screen with ×M resolution.

When N is much smaller than M, after directly mapping the dot matrix composed of N×N infrared sensors to the touch screen with M×M pixels, there are too few mapped pixels, so the final simulated sliding effect is not smooth, It gives the user the feeling that one card is one card, and the experience is not good. Therefore, in the embodiment of the present invention, interpolation processing can be performed on the N×N pixel points to be mapped among the M×M pixel points on the touch screen, so that the N×N pixel points become N ₁ ×N ₂ pixels points, wherein, N ₁ =N×x, N ₂ =N×y, and x and y are interpolation multiples respectively.

For example, for a touch screen with a dot matrix composed of 50×50 infrared sensors mapped to 3000×3000 pixels, since the distance between 50 and 3000 is 60 times, it can be considered that 50 is much smaller than 3000, so that the 50×50 infrared sensors are directly After the formed dot matrix is mapped to a touch screen with 3000×3000 pixels, there are too few pixels to be mapped (only 50, which is too few compared to 3000), so the final simulated sliding effect is not smooth, giving the user a feeling of It's one card for one card, and the experience is not good. In the embodiment of the present invention, if a dot matrix composed of 50×50 infrared sensors is mapped to a touch screen with 3000×3000 pixels, then 3000 will be divided into 50 equal parts, and every interval of 60 pixels will be divided into 50×50 pixels. One infrared sensor in the dot matrix composed of infrared sensors corresponds, that is, the first infrared sensor in each column or row of the dot matrix composed of 50×50 infrared sensors corresponds to the corresponding column in the 3000×3000 pixel points Or the 60th pixel of the corresponding row, the second infrared sensor corresponds to the 120th pixel of the corresponding column or row in the 3000×3000 pixels, ..., the 50th infrared sensor corresponds to 3000×3000 pixels The 3000th pixel of the corresponding column or corresponding row in . If interpolation is performed on the 50×50 pixels to be mapped among the 3000×3000 pixels on the touch screen, for example, interpolation is performed according to the interpolation multiple of 10 times, which is equivalent to 3000 pixels in each column or row , insert a pixel every 6 pixels from the first pixel to the 60th pixel, that is, insert a total of 10 pixels from the first pixel to the 60th pixel, and insert a pixel at the 61st pixel Insert a pixel at intervals of 6 pixels from the point to the 120th pixel, that is, insert a total of 10 pixels from the 61st pixel to the 60th pixel, ..., from the 2941st pixel to the 2941st pixel A pixel is inserted every 6 pixels in the 3000 pixels, that is, a total of 10 pixels are inserted from the 2941st pixel to the 300th pixel. In this way, a total of 500 pixels are inserted, plus the mapped There are 50 pixels in the 3000×3000 pixels, and each row or column in the 3000×3000 pixels is a total of 550 pixels. Compared with the 50 pixels before interpolation, after mapping and then simulating gesture sliding, the fluency can be greatly improved. Reduce the feeling of one card one card.

S102. Capturing gestures on the screen composed of N×N dot-matrix infrared sensors.

In the embodiment of the present invention, when the finger slides on the screen formed by the dot matrix infrared sensor, each infrared sensor in the dot matrix sensor can capture sensor data; Capture gestures on the screen composed of N×N dot matrix infrared sensors (dot matrix composed of N×N sensors).

Because some users may immediately return to the starting position when swiping their fingers from one place to another. According to the user's wishes, returning to the starting position for a short time should not be recognized. If recognized, it is misidentified. In order to prevent this from happening, in the embodiment of the present invention, after capturing the gesture on the screen formed by the dot-matrix infrared sensor, the method further includes: using a compensation algorithm to process misrecognized actions. Specifically, it is possible to first determine the sliding direction of the gesture when it slides from the initial position to the target position on the screen composed of N×N dot matrix infrared sensors, and then, if within a preset time, for example, within 800ms, the gesture Returning from the target position to the starting position in the direction opposite to the sliding direction, then filter the event generated by the gesture returning from the target position to the starting position in the direction opposite to the sliding direction. Once this type of event is filtered, the subsequent system will not respond to the gesture, so there will be no sliding effect.

S103, calculate the sliding distance d' corresponding to the sliding distance d on the touch screen with M×M pixels when the gesture slides on the screen composed of N×N dot matrix infrared sensors.

Specifically, as an embodiment of the present invention, calculating the sliding distance d' corresponding to the gesture sliding distance d on the screen composed of N×N dot matrix infrared sensors on the touch screen with M×M pixels may include the following steps S1031 and Step S1032:

S1031. Calculate the gesture according to the distance from any point between the starting position to the target position to a straight line formed by any column of infrared sensors among the N×N infrared sensors and the distances between the arbitrary point and the N dot matrixes respectively A sliding distance d on the screen composed of N×N dot-matrix infrared sensors, wherein the target position is the end point when the gesture slides the distance d on the screen composed of N×N dot-matrix infrared sensors.

S1032, according to the formula d'=M×d/D, calculate the sliding distance d' on the touch screen with M×M pixels, where D is any array of dot matrix emission in the dot matrix formed by N×N infrared sensors signal coverage.

Take the dot matrix composed of 4×4 infrared sensors as an example, as shown in Figure 2-a. As shown in Figure 2-b, assume that any column of infrared sensor dot matrix in the 4×4 infrared sensors is 4 infrared sensors (shown by 4 black dots in the figure, the numbers are 1, 2, 3 and 4 respectively, the following Respectively referred to as infrared sensor 1, infrared sensor 2, infrared sensor 3 and infrared sensor 4) when the gesture is detected to slide from the initial position (shown by the black triangle in the figure) to the target position (shown by the circle in the figure), the initial position The distance to the target position is represented by d, and the coverage area of the 4 infrared sensors when transmitting signals is represented by D in the figure. The distance of a straight line formed by two infrared sensors) is represented by Lmin in the figure, and the distances between any point between the starting position and the target position (shown by a square black dot in the figure) and the four infrared sensors are respectively represented by L1, L2, and L3 and L4 said.

Assuming that only the infrared sensor 1 detects the target position at the initial position, and the distance from the initial position to the infrared sensor 1 is L11, as shown in Figure 2-c, then the position d1 from the initial position to the center point of the array detection can be calculated according to the triangle function to get Calculate d2 in the above figure in the same way, so that the distance d=d1+d2. If the infrared sensor 1 cannot detect the target position, the longitudinal position is calculated with the infrared sensor 2 as the coordinate point, and assuming that the detection range of the infrared sensor 1 is symmetrical up and down, that is, d=2×d1+d3, here it is assumed that the infrared sensor 2 The longitudinal distance calculated for the coordinate point.

After calculating the sliding distance d of the gesture on the screen composed of N×N dot matrix infrared sensors, according to the formula d’=M×d/D, it is easy to calculate the sliding distance d’ on the touch screen with M×M pixels.

S104, responding to the sliding distance d' on the touch screen with M×M pixels.

It can be seen from the method of simulating the sliding of the touch screen in the example of accompanying drawing 1 above, since the dot matrix composed of N*N infrared sensors can be mapped to the touch screen with M*M pixels, the screen captured on the screen composed of dot matrix infrared sensors After the gesture, calculate the sliding distance d' corresponding to the sliding distance d on the touch screen with M×M pixels when the gesture slides on the screen formed by the dot matrix infrared sensor. Therefore, the technical solution provided by the present invention slides the finger on the screen formed by the dot-matrix infrared sensor, which can simulate sticky messages similar to a touch screen, and realize the air sliding function similar to a touch screen.

Please refer to FIG. 3 , which is a schematic structural diagram of a device for simulating sliding on a touch screen provided by Embodiment 2 of the present invention. For ease of description, only parts related to the embodiments of the present invention are shown. The device for simulating touch screen sliding illustrated in FIG. 3 may be the subject of execution of the method for simulating touch screen sliding provided in the foregoing embodiments, which may be a smart terminal or a functional module thereof. The device for simulating touch screen sliding shown in Figure 3 mainly includes a mapping module 301, a gesture capture module 302, a distance calculation module 303 and a response module 304, and each functional module is described in detail as follows:

The mapping module 301 is configured to map the dot matrix formed by N×N infrared sensors to the touch screen with M×M pixels.

In the embodiment of the present invention, both N and M are natural numbers greater than 1, and N is not greater than M. The mapping module 301 maps the dot matrix formed by N×N infrared sensors to the touch screen with M×M pixels, which is equivalent to dividing every M pixels into N equal parts, each with M/N pixels, and then, In a dot matrix composed of N×N infrared sensors, the first infrared sensor in each column or row of dot matrix corresponds to the M/Nth pixel in the corresponding column or row of M×M pixels, and the second The infrared sensor corresponds to the 2M/Nth pixel in the corresponding column or row of M×M pixels, ..., the Nth infrared sensor corresponds to the Mth pixel in the corresponding column or row of M×M pixels point. For example, for a dot matrix composed of 50×50 infrared sensors, if the mapping module 301 is to map it to a touch screen with 300×300 pixels, 300 will be divided into 50 equal parts, and every 6 pixels will be divided into 50× One infrared sensor in the dot matrix composed of 50 infrared sensors corresponds. Specifically, the first infrared sensor in each column or row of the dot matrix composed of 50×50 infrared sensors corresponds to the sixth pixel in the corresponding column or row in the 300×300 pixels, and the second The first infrared sensor corresponds to the 12th pixel in the corresponding column or row of 300×300 pixels, ..., the 50th infrared sensor corresponds to the 300th pixel in the corresponding column or row of 300×300 pixels . It should be noted that when M/N is not an integer, M/N is rounded down or rounded up depending on the situation. Once the dot matrix composed of N×N infrared sensors is mapped to the touch screen with M×M pixels, the continuous sensor (Sensor) data generated by gesture movements can be converted into continuous motion event (MotionEvent) data, which is equivalent to M The data generated by the touch screen with ×M resolution.

The gesture capture module 302 is configured to capture gestures on the screen formed by N×N dot matrix infrared sensors.

In the embodiment of the present invention, when the finger slides on the screen formed by the dot-matrix infrared sensors, each infrared sensor in the dot-matrix sensor can capture sensor data; The module 302 can capture gestures on the screen formed by N×N dot-matrix infrared sensors (a dot matrix composed of N×N sensors).

The distance calculation module 303 is used to calculate the distance d' corresponding to the sliding distance d' on the touch screen of M * M pixel points when the gesture slides the distance d on the screen formed by the N * N dot matrix infrared sensor;

A response module 304, configured to respond to the distance d' sliding on the touch screen with M×M pixels.

It should be noted that, in the embodiment of the device for simulating touch screen sliding shown in Fig. 3 above, the division of each functional module is only for illustration. Considering that the above function allocation is completed by different functional modules, that is, the internal structure of the device for simulating touch screen sliding is divided into different functional modules to complete all or part of the functions described above. Moreover, in practical applications, the corresponding functional modules in this embodiment may be implemented by corresponding hardware, or may be completed by corresponding hardware executing corresponding software. For example, the aforementioned mapping module may be capable of executing the aforementioned N× The dot matrix formed by N infrared sensors is mapped to the hardware of the touch screen with M×M pixels, such as a mapper, or it can be a general processor or other hardware device capable of executing the corresponding computer program to complete the aforementioned functions; as mentioned above The gesture capture module can be hardware that executes gestures captured on the screen formed by the dot matrix infrared sensor, such as a gesture capture device, or can be a general processor or other hardware device capable of executing a corresponding computer program to complete the aforementioned functions ( Each of the embodiments provided in this specification can apply the above description principle).

It can be seen from the device for simulating the sliding of the touch screen in the example of accompanying drawing 3 that since the mapping module can map the dot matrix formed by N*N infrared sensors to the touch screen of M*M pixels, the gesture capture module captures the dot matrix infrared sensor After the gesture on the screen is formed, the distance calculation module calculates the sliding distance d' corresponding to the sliding distance d' on the touch screen with M×M pixels when the gesture slides the distance d on the screen formed by the dot matrix infrared sensor. Therefore, the technical solution provided by the present invention slides the finger on the screen formed by the dot-matrix infrared sensor, which can simulate sticky messages similar to a touch screen, and realize the air sliding function similar to a touch screen.

The device for simulating sliding on a touch screen illustrated in FIG. 3 may further include an interpolation module 401 , as shown in FIG. 4 , the device for simulating sliding on a touch screen provided in Embodiment 3 of the present invention. The interpolation module 401 is used for if N is much smaller than M, the mapping module 301 maps the dot matrix formed by N×N infrared sensors to the touch screen with M×M pixels, and the M×M pixels on the touch screen are about to be The mapped N×N pixels are interpolated so that N×N pixels become N ₁ ×N ₂ pixels, where N ₁ =N×x, N ₂ =N×y, x and y are respectively is the interpolation multiple.

When N is much smaller than M, after the mapping module 301 directly maps the dot matrix formed by N×N infrared sensors to the touch screen with M×M pixels, there are too few mapped pixels, so the final simulated sliding effect It is not smooth, and the user feels that there is one card and one card, and the experience is not good. Therefore, in the embodiment of the present invention, the interpolation module 401 can perform interpolation processing on the N×N pixel points to be mapped among the M×M pixel points on the touch screen, so that the N×N pixel points become N ₁ ×N ₂ pixels, where N ₁ =N×x, N ₂ =N×y, and x and y are interpolation multiples respectively.

For example, for a touch screen with a dot matrix composed of 50×50 infrared sensors mapped to 3000×3000 pixels, since 50 and 3000 are 60 times apart, it can be considered that 50 is much smaller than 3000, so the mapping module 301 directly converts 50×50 After the dot matrix composed of three infrared sensors is mapped to the touch screen with 3000×3000 pixels, the mapped pixels are too few (only 50, which is too few compared to 3000), so the final simulated sliding effect is not smooth, giving The user feels that there is one card and one card, and the experience is not good. In the embodiment of the present invention, if the mapping module 301 maps a dot matrix composed of 50×50 infrared sensors to a touch screen with 3000×3000 pixels, the 3000 is divided into 50 equal parts, and every interval of 60 pixels is divided by 50 One infrared sensor in the dot matrix composed of ×50 infrared sensors corresponds, that is, the first infrared sensor in each column or row of the dot matrix composed of 50×50 infrared sensors corresponds to 3000×3000 pixels The 60th pixel in the corresponding column or row, the second infrared sensor corresponds to the 120th pixel in the corresponding column or row of 3000×3000 pixels, ..., the 50th infrared sensor corresponds to 3000×3000 The 3000th pixel of the corresponding column or corresponding row in the pixels. If the interpolation module 401 performs interpolation processing on the 50×50 pixels to be mapped among the 3000×3000 pixels on the touch screen, for example, interpolating according to the interpolation multiple of 10 times, it is equivalent to 3000 pixels in each column or row Among the pixels, a pixel is inserted at intervals of 6 pixels from the first pixel to the 60th pixel, that is, a total of 10 pixels are inserted from the first pixel to the 60th pixel. From the 61st pixel to the 120th pixel, insert a pixel every 6 pixels, that is, insert a total of 10 pixels from the 61st pixel to the 60th pixel, ..., at the 2941st pixel From the point to the 3000th pixel, a pixel is inserted at intervals of 6 pixels, that is, a total of 10 pixels are inserted from the 2941st pixel to the 300th pixel. In this way, a total of 500 pixels are inserted, plus For the 50 pixels mapped above, each row or column of 3000×3000 pixels has a total of 550 pixels. Compared with the 50 pixels before interpolation, simulating gesture sliding after mapping can greatly improve Fluency, reducing the feeling of one card after another.

The device for simulating sliding on the touch screen illustrated in FIG. 3 may further include a misrecognition processing module 501 , such as the device for simulating sliding on the touch screen provided in Embodiment 4 of the present invention as shown in FIG. 5 .
