The present disclosure relates to the field of data processing technologies, and in particular, to a data reporting method and apparatus, and a terminal device.
A touchscreen system generally includes a touchscreen controller and a touch detection apparatus. The touch detection apparatus is adapted to detect touch operation information on a touchscreen, and the touchscreen controller is adapted to receive the touch operation information from the touch detection apparatus, convert the touch operation information into touch data, and then send the touch data to an application processor. In addition, the touchscreen controller can receive a command sent by the application processor and execute the command.
In the prior art, when a touch operation occurs, a touchscreen system generally reports touch data to an upper-layer application program using a highest report rate. For example, in a tapping event, from touching a touchscreen to leaving the touchscreen by a finger of a user, the touchscreen system reports four to eight points to the upper-layer application program. When reporting touch data each time, the touchscreen system causes an application processor to generate an interrupt for data processing. In an actual test, when the application processor processes interrupt information such as a tapping operation and sliding operation on a touchscreen, a 100-130mA system current is increased, which greatly increases system power consumption, and most of the power consumption thereof is generated by the application processor. Currently, reducing power consumption generated when the application processor processes a touchscreen interrupt event is an urgent problem to resolve.
In view of this, the present disclosure provides a data reporting method and apparatus, and a terminal device, which are used to resolve a problem in the prior art that power consumption generated when an application processor processes a touchscreen interrupt event is relatively large, and technical solutions of the present disclosure are as follows:

Referring to
Step S101: Receive current touch operation information.
When a user performs a touch operation on a touchscreen, a touchscreen system detects current touch operation information, and receives the current touch operation information.
Step S102: Determine, using the current touch operation information, an area that is on a current interface of a touchscreen and in which the current touch operation information is located, and use the area as an operation area.
In a possible implementation manner, the current touch operation information may include touch location information, where the touch location information can indicate a location, of the current touch operation information, on the current interface of the touchscreen. Because the current interface of the touchscreen includes multiple areas, location information of each area on the current interface of the touchscreen may be acquired in advance. Matching is performed on the touch location information in the received current touch operation information and the location information of each area to determine an area that is on the current interface of the touchscreen and to which the touch location information belongs, where the area to which the touch location information belongs is the operation area.
Step S103: Determine attribute information of the operation area based on the correspondence between an area and attribute information.
The attribute information of the operation area includes a rate type of an area reported point of the operation area and touch operation information to which the operation area can respond. The rate type of the area reported point of the operation area may be used to indicate whether the operation area is a high-speed point reporting area or a low-speed point reporting area. The touch operation information to which the operation area can respond may be used to indicate a touch operation to which the operation area can respond.
Exemplarily, it is assumed that includes at least a first area and a second area, where the first area is a low-speed point reporting area, and the second area is a high-speed point reporting area. Attribute information corresponding to the first area comprises a rate type of an area reported point is a low speed, and touch operation information that can be responded to include la, lb, and lc; attribute information corresponding to the second area comprises a rate type of an area reported point is a high speed, and touch operation information that can be responded to include ha, hb, and hc. Assuming that it is determined, using the touch location information in the current touch operation information, that the operation area is the first area, the attribute information of the operation area is the attribute information corresponding to the first area, that is, the rate type of the area reported point is the low speed, and the touch operation information that can be responded to includes la, lb, and lc.
Step S104: Determine, from the current touch operation information according to the current touch operation information and the attribute information of the operation area, touch data reported to an application processor, and report the data.
The attribute information of the operation area includes the rate type of the area reported point and the touch operation information to which the operation area can respond. Whether the current touch operation information can be responded to by the operation area may be determined using the touch operation information, in the attribute information, to which the operation area can respond. When the current touch operation information can be responded to by the operation area, the to be reported touch data may be determined according to an operation type of the current touch operation information and the rate type of the area reported point. For example, when the operation type of the current touch operation information is a touch-tap type, the to be reported data is start touch data and end touch data; when the operation type of the current touch operation information is a consecutive type, the to be reported touch data is determined according to a report rate corresponding to the rate type of the area reported point.
An interface of a touchscreen generally includes multiple areas, such as a key area and a handwriting area. Different areas have different data reporting requirements. For example, a relatively low report rate is required in the key area, and a relatively high report rate is required in a drawing area, the handwriting area, and the like. From this point of view, according to the data reporting method provided in this embodiment of the present disclosure, attribute information corresponding to each area on a current interface of a touchscreen is acquired in advance. After touch operation information is received, in order to determine to be reported data, an area in which the touch operation information is located needs to be determined first; and after the area in which the touch operation information is located is determined, to be reported touch data may be further determined according to attribute information corresponding to the determined area and reported. According to the method provided in this embodiment of the present disclosure, to be reported touch data may be determined according to attribute information of an area in which current touch operation information is located and the current touch operation information, so that areas that have different data reporting requirements report touch data using different report rates. Compared with that a touchscreen always reports touch data according to a highest report rate in the prior art, according to the data reporting method provided in this embodiment of the present disclosure, a quantity of interrupts is reduced for an application processor, and usage of the application processor is decreased, thereby reducing power consumption generated when the application processor processes a touchscreen interrupt event.
Referring to
Step S201: Receive current touch operation information.
When a user performs a touch input operation on a touchscreen, a touchscreen system detects current touch operation information, and receives the current touch operation information.
Step S202: Determine, using the current touch operation information, an area that is on a current interface of a touchscreen and in which the current touch operation information is located, and use the area as an operation area.
In a possible implementation manner, the current touch operation information may include touch location information, where the touch location information can indicate a location, of the current touch operation information, on the current interface of the touchscreen. Because the current interface of the touchscreen includes multiple areas, location information of each area on the current interface of the touchscreen may be acquired in advance. Matching is performed on the touch location information in the received current touch operation information and the location information of each area to determine an area that is on the current interface of the touchscreen and to which the touch location information belongs, where the area to which the touch location information belongs is the operation area.
Step S203: Determine attribute information of the operation area based on the correspondence between an area and attribute information.
The attribute information of the operation area includes a rate type of an area reported point of the operation area and touch operation information to which the operation area can respond. Further, the rate type of the area reported point of the operation area may be used to indicate whether the operation area is a high-speed point reporting area or a low-speed point reporting area. The touch operation information to which the operation area can respond may be used to indicate a touch operation to which the operation area can respond.
Exemplarily, it is assumed that includes at least a first area and a second area, where the first area is a low-speed point reporting area, and the second area is a high-speed point reporting area. Attribute information corresponding to the first area comprises a rate type of an area reported point is a low speed, and touch operation information that can be responded to includes la, lb, and lc; attribute information corresponding to the second area comprises a rate type of an area reported point is a high speed, and touch operation information that can be responded to includes ha, hb, and hc. Assuming that it is determined, using the touch location information in the current touch operation information, that the operation area is the first area, the attribute information of the operation area is the attribute information corresponding to the first area, that is, the rate type of the area reported point is the low speed, and the touch operation information that can be responded to includes la, lb, and lc.
Step S204: Determine, using touch operation information to which the operation area can respond, whether the current touch operation information can be responded to by the operation area.
The determining, using touch operation information to which the operation area can respond, whether the current touch operation information can be responded to by the operation area may include determining whether the current touch operation information can be matched with the touch operation information to which the operation area can respond; and if the current touch operation information can be matched with the touch operation information to which the operation area can respond, determining that the current touch operation information can be responded to by the operation area, that is, the current touch operation information is valid touch operation information; otherwise, determining that the current touch operation information cannot be responded to by the operation area, that is, the current touch operation information is invalid touch operation information.
For example, the touch operation information to which the operation area can respond includes: “Δ”, “”, “<”, and “
”. When the user enters “<” in the operation area, matching is performed on “
” and the touch operation information “Δ”, “
”, “<”, and “∠” to which the operation area can respond. Because touch operation information that matches “√” exists in the touch operation information to which the operation area can respond, it is determined that the current touch operation information can be responded to by the operation area. If the user enters “U” in the operation area, because no touch operation information that matches “U” exists in the touch operation information to which the operation area can respond, it is determined that the current touch operation information cannot be responded to by the operation area.
Step S205a: Determine, using the current touch operation information, an operation type of the current touch operation information when the current touch operation information can be responded to by the operation area.
The operation type of the current touch operation information may include a touch-tap type, such as a tapping operation, and a consecutive type, such as a sliding operation.
Step S206aa: Configure a preset quantity of reported points for the current touch operation information when the operation type of the current touch operation information is a touch-tap type, and determine, from the current touch operation information according to the preset quantity of reported points, touch data reported to an application processor.
In a possible implementation manner, the configuring a preset quantity of reported points for the current touch operation information when the operation type of the current touch operation information is a touch-tap type, and determining, from the current touch operation information according to the preset quantity of reported points, touch data reported to an application processor includes configuring a preset quantity of reported points for the current touch operation information when the operation type of the current touch operation information is the touch-tap type, where the preset quantity of reported points is 2; and determining, from the current touch operation information according to the preset quantity 2 of reported points, that the touch data reported to the application processor is start touch data and end touch data.
When a current touch operation is a touch operation of the touch-tap type, such as a tapping operation, considering that a tapping operation includes a long-time tapping operation and a short-time tapping operation, different data reporting manners are used for different tapping operations in this embodiment.
Step S301: Determine whether a touch time of a current touch operation of a touch-tap type is greater than preset duration.
Step S302a: If the touch time of the current touch operation of the touch-tap type is greater than the preset duration, report start touch data first, and when the current touch operation of the touch-tap type ends, report end touch data.
The start touch data corresponds to a tap-down operation of the current touch operation of the touch-tap type, and the end touch data corresponds to a lift-up operation.
A touch operation performed by the user on the touchscreen is generally a touch operation of the touch-tap type, and for the touch operation of the touch-tap type, only the start touch data corresponding to the tap-down operation and the end touch data corresponding to the lift-up operation are reported. Therefore, not only a quantity of interrupts processed by an application processor is greatly reduced, which significantly reduces power consumption of the application processor, but also a running speed of an application program is remarkably improved.
Step S302b: If the touch time of the current touch operation of the touch-tap type is less than or equal to the preset duration, report start touch data and end touch data simultaneously.
The foregoing steps provide a data reporting manner used when the operation type of the current touch operation information is a touch-tap type, and the following provides a data reporting manner used when the operation type of the current touch operation information is a consecutive type.
Step S206ab: Determine a report rate of the current touch operation information according to a rate type of an area reported point of the operation area when the operation type of the current touch operation information is a consecutive type, and determine, from the current touch operation information according to the determined report rate, touch data reported to an application processor.
In this embodiment, each area on the current interface is classified into at least two types of areas, where one is a high-speed point reporting area, and another one is a low-speed point reporting area. The high-speed point reporting area may be but is not limited to a handwriting area, a drawing area, and the like, and the low-speed point reporting area may be but is not limited to an icon area set for responding to a sliding operation, and the like. The high-speed point reporting area corresponds to a relatively high report rate, which may enable a written word or a drawn line to be smoother and more coherent. The low-speed point reporting area corresponds to a relatively low report rate, which may ensure that, on the premise that a touch operation can be properly responded to, a quantity of interrupts is reduced for the application processor, thereby reducing power consumption of the application processor.
Step S207: Report the determined touch data to the application processor.
The foregoing steps provide a data reporting manner used when the operation area can respond to the current touch operation information, and the following provides a data processing manner used when the operation area cannot respond to the current touch operation information.
Step S205b: When the current touch operation information cannot be responded to by the operation area, skip reporting the current touch operation information.
In the prior art, when current touch operation information cannot be responded to by an operation area, that is, when the current touch operation information is invalid touch operation information, a touchscreen system still reports touch data of the current touch operation information, and interrupts an application processor to perform data processing. In order to further reduce a quantity of interrupts for an application processor and reduce power consumption of the application processor, according to the method provided in this embodiment, when it is determined that current touch operation information cannot be responded to by an operation area, touch data of the current touch operation information is not reported.
According to the data reporting method provided in this embodiment of the present disclosure, after current touch operation information is received, an area in which the current touch operation information is located is determined as an operation area. Because the current touch operation information can be responded to by the operation area, or cannot be responded to by the operation area, whether the current touch operation information can be responded to by the operation area needs to be determined first. When the current touch operation information cannot be responded to by the operation area, in order to reduce a quantity of interrupts for an application processor so as to reduce power consumption of the application processor, touch data of the current touch operation information is not reported. When the current touch operation information can be responded to by the operation area, because a touch operation may be classified into a touch operation of a touch-tap type and a touch operation of a consecutive type, and touch operations of different operation types require different quantities of points for reporting touch data, if the current touch operation information can be responded to by the operation area, an operation type of the current touch operation information is determined. When the operation type of the current touch operation information is the touch-tap type, a preset quantity of reported points is configured for the current touch operation information, and the touch data of the current touch operation information is reported according to the preset quantity of reported points. When the operation type of the current touch operation information is the consecutive type, a report rate of the current touch operation information is determined according to a rate type of an area reported point of the operation area, and the touch data of the current touch operation information is reported according to the determined report rate.
According to the method provided in this embodiment of the present disclosure, a data reporting manner may be determined according to attribute information of an area in which current touch operation information is located and an operation type of the current touch operation information. For a touch operation of a touch-tap type, only data of two points, namely start touch data corresponding to a tap-down event and end touch data corresponding to a lift-up event, is reported. For a touch operation of a consecutive type, a report rate is determined according to a rate type of an area reported point of an area in which the touch operation is located, so that a high-speed point reporting area corresponds to a high report rate and a low-speed point reporting area corresponds to a low report rate; and touch data is reported according to the determined report rate. Compared with that a touchscreen always reports touch data according to a highest report rate in the prior art, according to the data reporting method provided in this embodiment, a quantity of interrupts is reduced for an application processor, and usage of the application processor is decreased, thereby reducing power consumption generated when the application processor processes a touchscreen interrupt event.
In any one of the foregoing embodiments, there are multiple implementation manners of determining, using the current touch operation information, the operation type of the current touch operation information when the current touch operation information can be responded to by the operation area.
Referring to
Step S401: Acquire a coordinate set of the current touch operation information when the current touch operation information can be responded to by the operation area.
The current touch operation information includes multiple touch location coordinates. The acquiring a coordinate set of the current touch operation information includes acquiring at least two touch location coordinates from the current touch operation information, and using the at least two touch location coordinates as the coordinate set of the current touch operation information.
Step S402: Determine whether the coordinate set of the current touch operation information is within a preset range.
In a possible implementation manner, the determining whether the coordinate set is within a preset range includes calculating a Euclidean distance between any two touch location coordinates in the coordinate set; and if all distances between every two touch location coordinates are less than a preset value, determining that the coordinate set is within the preset range. For example, the coordinate set includes a touch location coordinate a, a touch location coordinate b, and a touch location coordinate c, and a Euclidean distance between the touch location coordinate a and the touch location coordinate b, a Euclidean distance between the touch location coordinate a and the touch location coordinate c, and a Euclidean distance between the touch location coordinate b and the touch location coordinate c are calculated. If all the three Euclidean distances obtained by calculation are less than a set value d, it is determined that the coordinate set is within the preset range.
For a touch operation of the touch-tap type, for example, a tapping operation, when the user performs the tapping operation on the touchscreen with a finger, the finger generally does not move, that is, a location of the finger is unchanged, and correspondingly, a location coordinate of the tapping operation is unchanged. For a touch operation of the consecutive type, for example, a sliding operation, when the user performs the sliding operation on the touchscreen with a finger, the finger moves, that is, a location of the finger changes, and correspondingly, a location coordinate of the sliding operation changes. The operation type of the current touch operation information can be determined by determining whether the coordinate set of the current touch operation information is within the preset range.
Step S403a: If the coordinate set of the current touch operation information is within the preset range, determine that the operation type of the current touch operation information is the touch-tap type.
Step S403b: If the coordinate set of the current touch operation information is not within the preset range, determine that the operation type of the current touch operation information is the consecutive type.
Referring to
Step S501: Determine a touch speed of the current touch operation information when the current touch operation information can be responded to by the operation area.
The touch location information and touch time information of the current touch operation information are acquired, and the touch speed of the current touch operation information is determined using the touch location information and the touch time information.
Step S502: Determine whether the touch speed of the current touch operation information is less than a set speed value.
A touch operation of the touch-tap type, for example, a tapping operation, is generally a stationary touch operation, and when the user performs the tapping operation on the touchscreen with a finger, the finger generally does not move, that is, a moving speed of the finger is 0. A touch operation of the consecutive type, for example, a sliding operation, moves, and when the user performs the sliding operation on the touchscreen with a finger, the finger moves and has a moving speed. Therefore, the operation type of the current touch operation information can be determined by determining whether the touch speed of the current touch operation information is less than the set speed value.
Step S503a: If the touch speed of the current touch operation information is less than the set speed value, determine that operation type of the current touch operation information is the touch-tap type.
Step S503b: If the touch speed of the current touch operation information is greater than or equal to the set speed value, determine that operation type of the current touch operation information is the consecutive type.
In any one of the foregoing embodiments, there are multiple implementation manners of determining the report rate of the current touch operation information according to the rate type of the area reported point of the operation area when the operation type of the current touch operation information is the consecutive type, and reporting the touch data of the current touch operation information according to the determined report rate.
Referring to
Step S601: Determine, according to the rate type, in the attribute information, of the area reported point of the operation area, whether the operation area is a high-speed point reporting area or a low-speed point reporting area.
In this embodiment of the present disclosure, each area on the current interface of the touchscreen is classified into two types of areas in advance, that is, the high-speed point reporting area and the low-speed point reporting area, and a report rate corresponding to the high-speed point reporting area and a report rate corresponding to the low-speed point reporting area are preset. The report rate corresponding to the high-speed point reporting area is greater than the report rate corresponding to the low-speed point reporting area.
Step S602a: When the rate type, in the attribute information, of the area reported point of the operation area indicates that the operation area is the high-speed point reporting area, determine a report rate corresponding to the high-speed point reporting area as the report rate of the current touch operation information.
Step S603a: Report the touch data of the current touch operation information to the application processor according to the report rate corresponding to the high-speed point reporting area.
The foregoing steps provide a data reporting manner used when the operation area is the high-speed point reporting area, and the following provides a data reporting manner used when the operation area is the low-speed point reporting area.
Step S602b: When the rate type, in the attribute information, of the area reported point of the operation area indicates that the operation area is the low-speed point reporting area, determine a report rate corresponding to the low-speed point reporting area as the report rate of the current touch operation information.
Step S603b: Report the touch data of the current touch operation information to the application processor according to the report rate corresponding to the low-speed point reporting area.
It may be understood that reporting the touch data using the report rate corresponding to the low-speed point reporting area is essentially to filter out some useless touch data, and report useful touch data. It should be noted that the report rate corresponding to the low-speed point reporting area should meet the following: the to be reported touch data can be correctly responded to by the operation area.
In any one of the foregoing embodiments, the attribute information of each area on the current interface of the touchscreen may further include an original report rate of the area. Correspondingly, the attribute information of the operation area may further include an original report rate of the operation area. In this case, referring to
Step S701: Determine, according to the rate type, in the attribute information, of the area reported point of the operation area, whether the operation area is a high-speed point reporting area or a low-speed point reporting area.
Step S702a: When the rate type, in the attribute information, of the area reported point of the operation area indicates that the operation area is the high-speed point reporting area, determine the original report rate of the operation area as the report rate of the current touch operation information.
Step S703a: Report the touch data of the current touch operation information to the application processor according to the original report rate of the operation area.
The foregoing steps provide a data reporting manner used when the operation area is the high-speed point reporting area, and the following provides a data reporting manner used when the operation area is the low-speed point reporting area.
Step S702b: When the rate type, in the attribute information, of the area reported point of the operation area indicates that the operation area is the low-speed point reporting area, adjust the original report rate of the operation area according to a preset report rate adjustment rule, so that a report rate obtained by means of adjustment is less than the original report rate of the operation area, and determine the report rate obtained by means of adjustment as the report rate of the current touch operation information.
Step S703b: Report the touch data of the current touch operation information to the application processor according to the report rate obtained by means of adjustment.
The foregoing steps S702a-S703a provide a data reporting manner used when an operation area is a high-speed point reporting area. In addition to this manner, another data reporting manner may also be used. In a possible implementation manner, an original report rate of the operation area is adjusted according to a preset report rate adjustment rule, so that a report rate obtained by means of adjustment is greater than the original report rate of the operation area; the report rate obtained by means of adjustment is determined as a report rate of current touch operation information; and touch data of the current touch operation information is reported according to the report rate obtained by means of adjustment. For example, touch data is interpolated, so that an actual report rate doubles, and for a handwriting area, a drawing area, and the like, a written word or a drawn line may be smoother and more coherent. For a touch operation of a consecutive type, although a report rate of the high-speed point reporting area is improved and a quantity of interrupts is increased for an application processor, because there are few touch operations of the consecutive type in the high-speed point reporting area, and there are more touch operations of a touch-tap type and touch operations that are of the consecutive type and in a low-speed point reporting area, on the whole, using the data reporting method provided in this embodiment of the present disclosure, the quantity of interrupts is reduced for the application processor, thereby reducing power consumption of the application processor.
Referring to
An interface of a touchscreen generally includes multiple areas, such as a key area and a handwriting area. Different areas have different data reporting requirements. For example, a relatively low report rate is required in the key area, and a relatively high report rate is required in a drawing area, the handwriting area, and the like. From this point of view, the data reporting apparatus provided in this embodiment of the present disclosure acquires attribute information corresponding to each area on a current interface of a touchscreen in advance; after receiving touch operation information, in order to determine to be reported data, needs to first determine an area in which the touch operation information is located; and after determining the area in which the touch operation information is located, may further determine to be reported touch data according to attribute information corresponding to the determined area. The data reporting apparatus provided in this embodiment of the present disclosure may determine to be reported touch data according to attribute information of an area in which current touch operation information is located and the current touch operation information, so that areas that have different data reporting requirements report touch data using different report rates. Compared with that a touchscreen always reports touch data according to a highest report rate in the prior art, according to the data reporting apparatus provided in this embodiment of the present disclosure, a quantity of interrupts is reduced for an application processor, and usage of the application processor is decreased, and correspondingly, power consumption generated when the application processor processes a touchscreen interrupt event is reduced.

In the foregoing embodiments, there are multiple implementation manners of determining the report rate of the current touch operation information according to the rate type of the area reported point of the operation area when the operation type determining subunit 902 determines that the operation type of the current touch operation information is the consecutive type. A report rate corresponding to a high-speed point reporting area and a report rate corresponding to a low-speed point reporting area are preset. Referring to
