In this embodiment, multi-touch information input by a user, that is, initial touch information, may be acquired through a touch screen of the electronic device, that is, a preset touch screen.

The multi-touch information may be understood as touch information generated by simultaneously operating a predetermined touch screen with a plurality of touch objects (e.g., a plurality of hands or a plurality of fingers), and the touch information may include position information of a touch point, i.e., initial touch point position information, a synchronization event code, and the like. The effect of the synchronous event code may be understood as that the occurrence of the identification event, for example, the occurrence of the identification multi-touch or single-touch, that is, each time a preset touch screen senses a touch point, a synchronous event code may be generated, where the synchronous event code is a reported event code for a single touch point position, and when the preset touch screen senses the last touch point, a synchronous event code may be generated, where the synchronous event code is a reported event code for all touch point positions. The initial touch point position information may be understood as position information of each touch point on a preset touch screen during each multi-touch operation performed by a user. The touch chip may determine the last touch point of each multi-touch operation according to the logic configured by the touch chip, for example, according to the waiting time of the next touch point sensed by the touch screen, and if the waiting time exceeds a preset threshold, for example, 1s, the current touch point may be determined as the last touch point.
S102, touch data are determined according to the reported event code of the single touch point position, the reported event codes of all the touch point positions and the initial touch point position information, wherein the touch data comprise multi-point touch data.

The number of touch points may be determined according to a generation rule of the synchronization event code, if the generation rule is the generation rule described in the above example, the number of the synchronization event code is consistent with the number of the touch points, and the position data of each touch point may also be determined according to a generation rule of the initial touch point position information.
S103, writing the touch data into a multi-point touch device node, so that a preset application can complete the processing of the touch data by reading the data in the multi-point touch device node.
In this embodiment, a multi-touch device node may be created in advance by using a touch chip, and then the obtained multi-touch data may be written into the multi-touch device node, so that a preset application in an application layer may read the multi-touch data in the multi-touch device node, and perform further processing on a touch event corresponding to the multi-touch data, where the number of the multi-touch device node is generally the same as that of a preset touch screen.
The touch information processing method provided by the embodiment of the invention obtains initial touch information by using a preset touch screen, wherein the initial touch information comprises multi-point touch information, the multi-point touch information comprises a synchronous event code and initial touch point position information, the synchronous event code comprises a single touch point position reporting event code and all touch point position reporting event codes, and touch data is determined according to the single touch point position reporting event code, all touch point position reporting event codes and the initial touch point position information, wherein the touch data comprises multi-point touch data, and the touch data is written into a multi-point touch equipment node, so that a preset application can complete the processing of the touch data by reading data in the multi-point touch equipment node. According to the technical scheme of the embodiment of the invention, the multi-point touch information is obtained by utilizing the preset touch screen, the multi-point touch data is determined according to the synchronous event code and the initial touch point position information contained in the multi-point touch information, and the multi-point touch data is written into the multi-point touch equipment node, so that the preset application can read the data in the multi-point touch equipment node, and the problem that an interactive mode only supporting single-point touch in a SylixOS system is solved by identifying the multi-point touch data and storing the multi-point touch data into the newly created multi-point touch equipment node, and the use experience of a user is improved.

The advantages of such a configuration are that by creating a multi-touch device node or a single-touch device node, the compatibility of the SylixOS system is improved, so that the compatibility of the SylixOS system can meet both the requirements of single-touch operations and multi-touch operations, and the specific selection can be determined by developers through presetting configuration information.
Specifically, fig. 2 is a schematic diagram illustrating processing of touch information. The single-point touch information input by the user can also be acquired through a preset touch screen configured with a preset application (the touch device application in fig. 2). The single touch information may be understood as touch information generated by operating a predetermined touch screen with a single finger. The single-point touch device nodes comprise an old single-point touch device node, namely a first single-point touch device node, and a new single-point touch device node, namely a second single-point touch device node. The second single touch device node may be understood as a function extension node of the first single touch device node. According to the requirements of a driver developer or a target user, if the driver developer or the target user needs to make a multi-touch to come through human-computer interaction, configuration information, namely first preset configuration information, can be preset, if the first preset configuration information shows that a multi-touch node does not need to be created, namely the first preset configuration information is in single-touch configuration, the multi-touch device node is not created, and otherwise, the multi-touch node is created. If the multi-touch node does not need to be created, the matching performance of the second preset configuration information and the functions of the first node and the second node can be judged. And if the function of the first single-point touch equipment node is matched with that of the first node, creating a first single-point touch equipment node, and if the function of the second single-point touch equipment node is matched with that of the second node, creating a second single-point touch equipment node. The second preset configuration information may also be preset according to the requirements of a driver developer or a target user, for example, a data read-write speed is preset according to whether a faster response human-computer interaction experience is required, where the data read-write speed is the second preset configuration information, if the first node function can meet the data read-write speed, it may be determined that the first node function is matched with the second preset configuration information, and if the second node function can meet the data read-write speed, it may be determined that the second node function is matched with the second preset configuration information.
Optionally, as shown in fig. 2, if there are multiple preset touch screens (configured with the touch screen applied by the touch device in fig. 2), single-point touch information or multi-point touch information may be simultaneously obtained from different touch devices, and a multi-point touch device node (a new touch device node in fig. 2) and a second single-point touch device node are established, or a multi-point touch device node, a first single-point touch device node, a second single-point touch device node, and the like are established.
Optionally, the initial touch information further includes single-point touch information, and the single-point touch information and the multi-point touch information both include: the touch screen comprises time stamp information, event type information, event code information and event numerical values, wherein the event type information comprises touch position information or synchronous information, the event code information comprises touch position event codes or synchronous event codes, the touch position event codes comprise various types of position identifications, the event numerical values corresponding to the touch position event codes are used for representing position coordinates corresponding to each position identification, and the synchronous event codes of the single-point touch information comprise reported event codes of all touch point positions. The advantage of setting up like this is, through defining the data content of initial touch information, can accurate acquisition by the key information that touch operation produced, improved the accuracy of the touch event that touch operation triggered.
Specifically, the single-touch information and the multi-touch information may be composed of four parts, that is, timestamp information, event type information, event code information, and event value. When the event type information in the single-touch information and the multi-touch information is touch POSITION information, which can be represented by EV _ ABS, the corresponding event code information is a touch POSITION event code, the POSITION identifiers in the touch POSITION event code may be ABS _ MT _ POSITION _ X and ABS _ MT _ POSITION _ Y, ABS _ MT _ POSITION _ X represents an X axis, ABS _ MT _ POSITION _ Y represents a Y axis, and the corresponding event value represents the POSITION coordinate corresponding to each POSITION identifier, such as when the touch POSITION event code is ABS _ MT _ POSITION _ X and the corresponding event value is 10, the abscissa represents the touch point, and when the touch POSITION event code is ABS _ MT _ POSITION _ Y and the corresponding event value is 2, the ordinate represents the touch point. When the event type information in the single-point touch information and the multi-point touch information is the synchronization information, the corresponding event code information is a synchronization event code, which can be represented by EV _ SYN, the synchronization event code of the single-point touch information only includes event codes in which all touch point positions are reported, and can be represented by SYN _ REPORT, the synchronization event code of the multi-point touch information includes an event code in which a single touch point position is reported and event codes in which all touch point positions are reported, the event code in which a single touch point position is reported can be represented by SYN _ MT _ REPORT, and the event number value corresponding to the synchronization event code can be a preset identifier, such as 0.
Optionally, when the initial touch information is the multi-touch information, the multi-touch information includes a plurality of pieces of sub-touch information, each piece of sub-touch information includes the timestamp information, the event type information, the event code information, and the event value, the all-touch-point-position-reported event code is used to indicate that the initial touch point position information of all touch points has been reported, and the single-touch-point-position-reported event code is used to indicate that the initial touch point position information of one touch point has been reported. The touch event triggering method has the advantages that the ordering of the touch information of each touch point is ensured through the plurality of sub-touch information of the initial touch information, and accordingly the accuracy of the touch event corresponding to the touch information triggered subsequently is ensured.
For example, when the initial touch information is multi-touch information and the multi-touch information is touch information of two points, the multi-touch information may include at least 4 sub-touch information including touch position information and 2 sub-touch information including synchronization information, for a total of 6 sub-touch information. In the 4 sub-touch information containing touch position information, every two adjacent sub-touch information containing touch position information are in a group, the group of sub-touch information contains a complete position coordinate of a touch point, namely a position coordinate containing an abscissa and an ordinate, the adjacent sub-touch information after the first group of sub-touch information can be sub-touch information containing a single touch point position reported event code, and the adjacent sub-touch information after the second group of sub-touch information, namely the last group, can be sub-touch information containing all touch point position reported event codes. When the initial touch information is single-point touch information, at least 2 sub-touch information containing touch position information and 1 sub-touch information containing synchronization information in the single-point touch information may be included, and the total number of the sub-touch information is 3. The 2 sub-touch information containing touch position information includes a complete position coordinate of a touch point, that is, a position coordinate including an abscissa and an ordinate, and the sub-touch information adjacent to the 2 sub-touch information may be sub-touch information including event codes reported at all touch point positions.

The advantage of setting up like this has accurately confirmed the number and the positional information of touch point, has guaranteed human-computer interaction's effect.
Optionally, the writing the touch data into a multi-touch device node includes: storing the number of the touch points and the position information of the target touch point into a preset kernel message queue according to the time sequence according to the timestamp information; and when the multi-point touch equipment node is in an open state, writing the number of the touch points and the position information of the target touch point into the multi-point touch equipment node according to the arrangement sequence in the preset kernel message queue. The method has the advantages that the method can guarantee the follow-up ordered processing of the touch events corresponding to the touch points, and the reliability of human-computer interaction is improved.

Specifically, a touch device base library may be created in advance in the SylixOS system, and the touch device base library may be used to store and manage various information related to the touch operation, such as registration interface information of the touch driver, that is, driver registration interface information, and by calling the driver registration interface information, registration of the touch driver may be completed. If the registration is successful, multiple touch interfaces of the touch device, namely device interfaces such as an internal integrated circuit interface and a universal serial bus interface, can be created, and initial touch information can be acquired from a preset touch screen by using the interfaces. The touch device base library can also be used for storing and managing unloading information of a touch driver, interface information of a touch device node, touch position information, touch device private data and the like, the touch device private data comprises configuration information such as the model of a touch chip and the like, the touch device private data is usually created by the touch driver, in addition, registration and execution of an interrupt processing function and processing of touch chip reset logic are also completed by the touch driver, for example, the touch chip is reset by using a reset pin of a General Purpose Input/Output Port (GPIO), and the function of the interrupt processing function comprises that when a preset touch screen senses a touch point, information is sent to a central processing unit through the GPIO pin to inform the central processing unit of the occurrence of the touch action, the central processing unit can call the interrupt processing function, and the touch position information is acquired from the touch chip and analyzed.
