[0027] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same 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 disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] Before introducing the touch detection method, device, terminal and storage medium provided by the present disclosure, the application scenarios involved in each embodiment of the present disclosure are first introduced. The present disclosure is applied to the scenario where the user performs a touch operation on the touch screen of the terminal. In the related technology, after detecting the user's touch operation on the touch screen, the touch point data is collected by the touch chip. When the collection of the touch point data is completed, the touch chip sends an interrupt signal to the processor. After receiving the interrupt signal, the processor starts to obtain the touch point data collected by the touch chip, processes the acquired touch point data, and generates a control instruction corresponding to the touch operation. Based on the above scenario, the inventor found that since the amount of collected touch point data is large, the processor will take a long time to obtain the touch point data, thereby affecting the generation time of the control instruction, that is, affecting the response speed of the touch screen, resulting in a poor user experience.

[0029] In order to solve the above problems, the present disclosure provides a touch detection method, device, terminal and storage medium, which can generate an interrupt signal in advance before the collection of touch point data is completed. Based on the interrupt signal, the touch operation is performed according to the collected touch point data. In this way, the time for processing touch point data can be effectively saved, and it is not necessary to wait until all touch point data are collected before processing the touch point data, thereby improving the response speed of the touch screen and enhancing the user experience.

[0030] Figure 1 FIG. 1 is a flow chart of a touch detection method according to an exemplary embodiment. The method is used in a terminal, which may be any device including a touch screen, such as but not limited to a mobile terminal, a tablet computer, a vehicle-mounted central control, etc. Figure 1 As shown, the method comprises the following steps:

[0031] In step S101, touch point data corresponding to the touch operation is collected.

[0032] When a user triggers a touch operation on the touch screen, each touch operation generates multiple touch points on the touch screen, and the touch chip of the terminal can detect the touch point data corresponding to each touch point of the touch operation, that is, the touch point data is collected in the touch chip and cached, so that the processor of the terminal can obtain the touch point data cached by the touch chip. Among them, the touch operation can include, for example, a click operation, a sliding operation, and a long press operation.

[0033] In step S102, when the collection time of the touch point data is greater than or equal to a preset time threshold, an interrupt signal is generated.

[0034] The preset time threshold is less than the total time required to complete the touch point data collection.

[0035] When the acquisition time of the touch point data is greater than or equal to the preset time threshold, an interrupt signal is generated and sent to the processor of the terminal. In this way, since the preset time threshold is less than the total time to complete the touch point data acquisition, the processor can receive the interrupt signal sent by the touch chip in advance, and after receiving the interrupt signal, start to acquire the touch point data cached by the touch chip, and process the acquired touch point data. The processor does not need to wait until the touch chip completes the acquisition of all the touch point data before starting to acquire the touch point data, which effectively saves the time for processing the touch point data and improves the response speed of the touch screen.

[0036] In step S103, based on the interrupt signal, a touch operation is performed according to the collected touch point data.

[0037] It can be understood that after the touch chip generates an interrupt signal, the interrupt signal is sent to the processor. After receiving the interrupt signal, the processor starts to obtain the touch point data cached by the touch chip. And based on the acquired touch point data, the coordinates corresponding to the touch point data are calculated. According to the calculated coordinates and the current interface information of the terminal, a control instruction corresponding to the touch operation is generated, and the control instruction is executed. Among them, the interface information includes the coordinate information of all icons in the interface currently displayed by the terminal. For example, if the interface currently displayed by the terminal is a telephone dialing interface, the interface information may include the coordinate information of each digital button icon and the dial button icon.

[0038] For example, the coordinates corresponding to the touch point data can be calculated by a centroid algorithm based on the acquired touch point data, wherein the centroid algorithm can refer to related technologies and will not be described in detail here. The coordinates corresponding to the acquired touch point data are compared with the current interface information of the terminal to determine the target icon corresponding to the touch operation in the current interface, and the control instruction corresponding to the touch operation is generated in combination with the touch point data.

[0039] For example, if the interface currently in which the terminal is located is the main interface of the desktop, the user's touch operation on the terminal touch screen is sliding to the left. Accordingly, after detecting the user's touch operation, the touch chip collects the touch point data corresponding to each touch point of the user's touch operation, caches the touch point data, and sends an interrupt signal to the processor when the acquisition time is greater than or equal to the preset time threshold. After receiving the interrupt signal, the processor starts to obtain the touch point data cached by the touch chip. The processor calculates the coordinates corresponding to the touch point data based on the acquired touch point data, generates a control instruction for controlling the main interface of the desktop to slide to the left based on the coordinates and the interface information of the current terminal, and executes the control instruction, that is, the terminal slides from the main interface to the interface on the right side of the main interface. If the interface currently in which the terminal is located is a telephone dialing interface, the user's touch operation on the terminal touch screen is clicking the dial button. Similarly, after detecting the user's touch operation, the touch chip collects the touch point data corresponding to each touch point of the user's touch operation, caches the touch point data, and sends an interrupt signal to the processor when the acquisition time is greater than or equal to the preset time threshold. After receiving the interrupt signal, the processor starts to obtain the touch point data cached by the touch chip. The processor calculates the coordinates corresponding to the touch point data based on the acquired touch point data, generates a control instruction for controlling the dialing based on the coordinates and the interface information of the current terminal, and executes the control instruction, that is, dials the server.

[0040] By adopting the above method, an interrupt signal can be generated in advance before the collection of touch point data is completed. Based on the interrupt signal, the touch operation is performed according to the collected touch point data. In this way, the time for processing touch point data can be effectively saved, and the touch point data does not need to be processed until all touch point data are collected, thereby improving the response speed of the touch screen and enhancing the user experience.

[0041] The following is an explanation of the setting of the preset time threshold in the above method. Figure 2 As shown, the preset time threshold can be obtained by following the steps below:

[0042] S1: Determine a preset total amount of touch point data to be collected.

[0043] The preset total data volume is the maximum data volume that the terminal can collect.

[0044] S2: Acquire a preset communication rate for data communication between a processor of the terminal and a touch chip of the terminal, and acquisition capability information of the touch chip for acquiring touch point data.

[0045] The acquisition capability information of the touch chip may include a preset acquisition rate of the touch chip and a preset amount of data acquired by the touch chip in a single time.

[0046] In some embodiments, the total transmission time required for the processor to acquire the touch point data corresponding to the preset total data volume from the touch control chip can be determined according to the preset communication rate and the preset total data volume of the processor.

[0047] The amount of touch point data acquired by the processor is numerically equal to the amount of touch point data collected by the touch chip, to ensure that the touch point data acquired by the processor is all touch point data collected by the touch chip, avoiding omission of touch point data.

[0048] For example, the ratio of the preset total data volume to the preset communication rate can be used as the total transmission time. 1 , the preset total amount of data to be acquired is d, then the total transmission time t required for the processor to acquire the touch point data corresponding to the preset total amount of data from the touch chip can be calculated by the formula t = d / s 1 get.

[0049] In some embodiments, the data collection time of the touch chip can be determined according to the preset total data volume and the preset collection rate, wherein the data collection time represents the time required for the touch chip to complete the collection of the preset total data volume at the preset collection rate.

[0050] For example, the ratio of the preset total data volume to the preset acquisition rate can be used as the data acquisition time. For example, if the preset total data volume to be collected is d, and the preset acquisition rate of the touch chip is s 2 , then the data acquisition time T of the touch chip can be calculated by the formula T = d / s 2 get.

[0051] It should be noted that the touch chip uses a segmented acquisition method when collecting touch point data, that is, the touch chip divides the data to be collected into multiple groups, and collects one group of data each time. For example, the touch chip needs to collect m×n touch point data (that is, m rows and n columns of data), and can collect j rows (where j is greater than or equal to 1) of data each time, so the touch chip needs to collect m×n touch point data m / j times.

[0052] It should be noted that before the processor obtains the last set of touch point data, the touch chip has completed the collection of the last set of touch point data, so that it can be ensured that data communication and data collection will not conflict. Therefore, in this embodiment, the single transmission time required for the processor to obtain a set of touch point data can also be determined, and the preset time threshold is determined according to the single transmission time.

[0053] In some embodiments, the single transmission time required for the processor to obtain the preset amount of data from the touch chip can be determined according to a preset communication rate and a preset amount of data collected by the touch chip at a single time.

[0054] For example, the ratio of the preset data volume to the preset communication rate can be used as the single transmission time required for the processor to obtain the preset data volume from the touch chip. 1 , the preset amount of data collected by the touch chip at a time is c, then the single transmission time t required for the processor to obtain the preset amount of data from the touch chip i It can be obtained by formula t i =c / s 1 get.

[0055] S3: Determine a preset time threshold according to a preset total data volume, a preset communication rate and the acquisition capability information.

[0056] Accordingly, step S3 may determine a preset time threshold according to the above-mentioned total transmission time, data collection time and single transmission time.

[0057] In some embodiments, first, a first time difference between the total transmission time and the single transmission time may be calculated.

[0058] For example, if the total transmission time is t and the single transmission time is t i , then we can get the total transmission time t and the single transmission time t i The first time difference t 1 =tt i .

[0059] Secondly, a second time difference between the data collection time and the first time difference may be calculated.

[0060] For example, if the data collection time is T, the first time difference is t 1 , then we can get the data acquisition time T and the first time difference t 1 The second time difference t′=Tt 1 .

[0061] Finally, the preset time threshold can be obtained according to the second time difference.

[0062] The following describes how to obtain the preset time threshold according to the second time difference.

[0063] In a possible implementation manner, the second time difference may be used as a preset time threshold.

[0064] For example, if the preset total amount of data to be collected is 1000 data, the preset collection rate of the touch chip is 100 / ms, the preset amount of data collected in a single time is 100 data, and the preset communication rate of the processor is 1000 / ms. According to the preset communication rate of 1000 / ms and the preset total amount of data of 1000 data, it can be obtained that the total transmission time required for the processor to obtain the touch point data corresponding to the preset total amount of data (1000 data) from the touch chip is 1ms. According to the preset total amount of data of 1000 data and the preset collection rate of 100 / ms, it can be obtained that the data collection time of the touch chip is 10ms. According to the preset communication rate of 1000 / ms and the preset amount of data collected by the touch chip in a single time of 100 data, it can be obtained that the single transmission time required for the processor to obtain the preset amount of data is 0.1ms. The first time difference between the total transmission time of 1ms and the single transmission time of 0.1ms is calculated to be 0.9ms, and the second time difference between the data collection time of 10ms and the first time difference of 0.9ms is calculated to be 9.1ms. In this implementation, the second time difference value 9.1 ms may be used as the preset time threshold, that is, the preset time threshold is 9.1 ms.

[0065] In addition, considering that the touch chip is actually collecting touch point data and / or the processor is acquiring touch point data, due to some factors, the actual acquisition rate of the touch chip and / or the actual communication rate of the processor may fluctuate, which may cause the touch chip to have not completed the acquisition of the last set of touch point data before the processor acquires the last set of touch point data. In this way, there will be a conflict between the acquisition of touch point data by the processor and the acquisition of touch point data by the touch chip. Therefore, in order to ensure that the processor will not conflict with the acquisition of touch point data by the touch chip during the process of acquiring touch point data, that is, to ensure that the touch chip has completed the acquisition of the last set of data before the processor acquires the last set of data. Therefore, in another possible implementation of the present disclosure, the sum of the second time difference and the first preset time can also be used as a preset time threshold. Among them, the first preset time is a reserved buffer time to avoid fluctuations in the actual acquisition rate and / or the actual communication rate, resulting in a conflict between the acquisition of touch point data and the acquisition of touch point data.

[0066] For the sake of convenience, the data in the above example is used as an example. For example, if the first preset time is 0.05 ms, the sum of the second time difference 9.1 ms and the first preset time 0.05 ms can be used as the preset time threshold, that is, the preset time threshold is 9.15 ms.

[0067] Considering that the processor may need to perform data preprocessing after receiving the interrupt signal, to ensure that the touch point data can be transmitted normally between the processor and the touch chip.

[0068] For example, the data preprocessing performed by the processor may include one or more of the following processing operations:

[0069] Adjust the parameters of the external bus, where the external bus is used for data transmission between the processor and the touch chip; the external bus parameters may include, for example, bus width, bandwidth, and bus frequency. When there is no communication between the processor and the touch chip, in order to reduce power consumption, the processor may turn off the external bus clock or stop supplying power to the external bus when there is no communication. Therefore, when the processor communicates with the touch chip, it is necessary to adjust the parameters of the external bus to ensure normal communication with the touch chip.

[0070] Alternatively, when the current interface of the terminal contains multiple task windows, system scheduling is performed; if the terminal is a multi-tasking operating system, when the processor is communicating, the terminal interface may be in a multi-tasking window, that is, the current interface contains multiple applications. Then, the applications corresponding to the multiple task windows in the current interface can be scheduled according to the priority of each application to determine the target application to be controlled, so as to generate corresponding control instructions according to the acquired touch point data.

[0071] Alternatively, when the terminal is in a low power state, the low power state is switched to the communication state. When the processor and the touch chip do not communicate for a long time, the terminal may be in a low power state to reduce power consumption, and the processor and the touch chip will not communicate in the low power state. Therefore, when the processor and the touch chip communicate, it is necessary to switch from the low power state to the communication state.

[0072] Therefore, in another possible implementation, the data processing time corresponding to the processor can also be obtained. The data preprocessing time is the maximum time required for the processor to perform data preprocessing. The difference between the second time difference and the data processing time is used as the preset time threshold.

[0073] Among them, obtaining the data processing time corresponding to the processor may include the following two methods:

[0074] In a first approach, the preprocessing time of the processor performing data preprocessing may be used as the data processing time.

[0075] For the sake of ease of explanation, we will continue to use the data in the above example as an example. For example, if the preprocessing time is 0.1ms, that is, the data processing time is 0.1ms, the difference between the second time difference 9.1ms and the data processing time 0.1ms can be used as the preset time threshold, that is, the preset time threshold is 9ms.

[0076] In a second method, the sum of the preprocessing time and the second preset time may be used as the data processing time.

[0077] The second preset time is a buffer time reserved for data preprocessing to ensure that the processor can complete data preprocessing within the data processing time.

[0078] For the sake of ease of explanation, we will continue to use the data in the above example as an example. For example, if the preprocessing time is 0.1ms and the second preset time is 0.05ms, the data processing time can be obtained as 0.15ms. The difference between the second time difference of 9.1ms and the data processing time of 0.15ms can be used as the preset time threshold, that is, the preset time threshold is 8.95ms.

[0079] In another possible implementation, the difference between the sum of the second time difference and the first preset time and the data processing time may be used as the preset time threshold, wherein the data processing time includes the sum of the preprocessing time and the second preset time.

[0080] For the sake of ease of explanation, we will continue to use the data in the above example as an example. For example, the sum of the second time difference 9.1ms and the first preset time 0.05ms and the difference between the data processing time 0.15ms can also be used as the preset time threshold, that is, the preset time threshold is 9ms.

[0081] By adopting the above method, an interrupt signal can be generated in advance before the collection of touch point data is completed. Based on the interrupt signal, the touch operation is performed according to the collected touch point data. In this way, the time for processing touch point data can be effectively saved, and the touch point data does not need to be processed until all touch point data are collected, thereby improving the response speed of the touch screen and enhancing the user experience.
