Detailed Description
In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of embodiments of the application will be rendered by reference to the appended drawings and appended drawings.
Fig. 1 is a schematic flow chart of a touch pad control method according to an embodiment of the present disclosure, where the method may be performed by a processing device of the touch pad, and the device may be implemented in software and/or hardware, and optionally, may be implemented by an electronic device, where the electronic device may be a PC terminal including a touch pad or a device including a touch screen formed by a plurality of touch pads.
As shown in fig. 1, the method may include:
s101: and acquiring first touch information corresponding to the current touch operation.
When the processor detects that the user touches the touch pad, first touch information corresponding to the current touch operation is acquired, wherein the first touch information can comprise first position information and/or a first touch area. The first position information refers to coordinate information of the touch position on the touch pad, and may include a first start position and a first end position. The first touch area refers to the contact area between the finger or palm of the user and the touch pad. The processor may construct coordinates of the touch pad in advance, and determine corresponding position coordinates according to the first touch position when detecting the touch of the user.
S102: and acquiring second touch information corresponding to the previous effective touch operation.
In this embodiment, the processor may record touch information corresponding to each valid touch operation, and to determine the validity of the current touch operation, the processor will read, from the local memory, touch information corresponding to the previous valid touch operation, that is, second touch information, where the second touch information may include second location information and/or a second touch area. The second position information may include a second start position and a second end position of the previous effective touch operation, where the second touch area represents a corresponding contact area when the touch pad is touched during the previous effective touch operation.
S103: and determining whether the current touch operation is a valid touch operation according to the second touch information and the first touch information.
In determining whether the current touch operation is a valid touch operation, the last valid touch operation processor determines whether the current touch operation is a valid touch operation based on the first touch information and the second touch information. I.e. the processor determines to mask the current touch operation or to respond to the current touch operation.
Specifically, for different scenarios, it may be determined whether the current touch operation is valid through different processing schemes:
In the current anti-false touch operation, the touch pad is generally divided into a center area and an edge area, and as shown in fig. 2, an area 10% from the left and right sides of the touch pad and 2.5% from the upper and lower sides of the touch pad is defined as the edge area. If the user falls within the center region, then a valid touch operation is considered. If the user falls to the edge area, it is considered an invalid touch operation. However, in some application scenarios, the user slides from the center region to the edge region in one touch operation; in the next touch operation, the user directly starts sliding from the edge area, and the current false touch prevention processing logic is regarded as invalid touch operation to influence the actual operation of the user. Based on this, the present embodiment provides a processing method, specifically: determining a touch type corresponding to the current touch operation, wherein the touch type can comprise finger touch or palm touch; and determining that the current touch operation is an effective touch operation when the touch type corresponding to the current touch operation is finger touch, the second initial position of the previous effective touch operation is positioned in the central area of the touch pad, the second end position is positioned in the edge area of the touch pad, and the first initial position of the current touch operation is positioned in the edge area. Wherein the central region and the edge region may be preset.
That is, it is first determined whether the current touch operation is a finger touch or a palm touch. When determining that the touch type corresponding to the current touch operation is finger touch or palm touch, the method can be realized in such a way that the touch pad determines the touch type corresponding to the current touch operation according to the first touch area and reports the touch type to electronic equipment connected with the touch pad, the electronic equipment is not required to determine, the computing resource is saved, and the processing speed is improved. Wherein the first touch information may include a touch type. And the electronic equipment automatically judges the touch type corresponding to the current touch operation according to the first touch area in the first touch information. Specifically, the electronic device may determine, according to the first touch area and the first preset area threshold, a touch type corresponding to the current touch operation. The first preset area threshold may be a preset fingerprint area of a finger, for example, a fingerprint area of an index finger, and when the first touch area in the first touch information is smaller than or equal to the first preset area threshold, it may be that the finger of the user touches the touch pad, and it is determined that the finger touches; when the first touch area in the first touch information is larger than the first preset area threshold, it is possible that the palm of the user touches the touch pad, and the palm touch is determined. When the touch type corresponding to the current touch operation is determined to be finger touch, if the previous effective touch operation is started from the central area and stopped at the edge area, and the current touch operation is started from the edge area, the convenience and the possibility of actual operation are considered, and the current touch operation is determined to be the user intended touch operation, and the current touch operation is considered to be the effective touch operation.
The finger touch may include a single-finger touch and a double-finger touch, and when determining the touch type corresponding to the current touch operation, the touch type corresponding to the current touch operation may be determined to be a single-finger touch or a double-finger touch according to the first touch area and the second preset area threshold in the first touch information. The second preset area threshold may be a fingerprint area of a single finger, such as a fingerprint area of an index finger.
Further, based on the processing manner, even if the touch type of the current touch operation is finger touch, the previous effective touch operation is started from the central area, stopped at the edge area and the current touch operation is started from the edge area, if the moving distance of the finger of the user in the first preset time threshold value is smaller than the first preset distance threshold value in the current touch operation, determining that the current touch operation is an ineffective touch operation; and if the moving distance of the finger of the user in the first preset time threshold is greater than or equal to the first preset distance threshold, determining that the current touch operation is an effective touch operation. The first preset time threshold and the first preset distance threshold may be set according to an actual application scenario. For example, the first preset time threshold is 150ms, the first preset distance threshold is 200px (pixel distance), and if the moving distance of the user in 150ms is less than 200px, the current touch operation is determined to be an invalid touch operation, and the finger sliding is shielded. It should be noted that, in the present embodiment, the unit of the moving distance may be defined according to practical situations, and the present embodiment includes, but is not limited to, representing the moving distance by using pixels as a unit of measure.
In the current false touch prevention processing, a user slides on a touch pad by using a finger in general, and when the touch type corresponding to the current touch operation is determined to be palm touch, the user is determined to be unintentional touching the touch pad, and then the invalid touch operation is determined to be the shielded palm touch sliding operation. However, in some application scenarios, the user may actually slide with the palm, and based on this, the present embodiment provides a processing manner, specifically: when the touch type corresponding to the current touch operation is palm touch, determining the touch type corresponding to the effective touch operation at the previous time; and when the touch type corresponding to the previous effective touch operation is finger touch, determining the current touch operation as the effective touch operation. That is, if the touch type corresponding to the previous valid touch operation is a finger touch, it is determined that the user wants to continue the touch sliding, and even if the touch type corresponding to the current touch operation is a palm touch, the current touch operation is determined to be the valid touch operation. That is, the processor responds to the current touch operation. The determining the touch type corresponding to the previous effective touch operation may be determining according to the second touch area, or reading the touch type corresponding to the previous effective touch operation from the local memory.
Optionally, to further improve the capability of preventing false touch, when the touch type corresponding to the previous effective touch operation is finger touch and the sliding distance of the previous effective touch operation is greater than the second preset distance threshold or the sliding time is greater than the second preset time threshold, determining that the current touch operation is the effective touch operation when the touch type corresponding to the current touch operation is palm touch. The second preset distance threshold and the second preset time threshold may be set according to actual application conditions. For example, the second preset distance threshold is 50px and the second preset time threshold is 150ms.
Optionally, to further improve the capability of preventing false touch, when the touch type corresponding to the current touch operation is palm touch and the touch type corresponding to the previous valid touch operation is finger touch, if the first end point position corresponding to the current touch operation is an edge area of the touch pad, determining that the current touch operation is an invalid touch operation.
It can be appreciated that, in practical application, even if the touch operation is a finger touch, there may be a single-finger touch or a double-finger touch scenario, and in order to handle the false touch operation under different scenarios, the present embodiment provides a scheme, specifically, when the touch type corresponding to the previous valid touch operation is a double-finger touch, the touch type corresponding to the current touch operation is a single-finger touch, and the current touch operation is not moved within a third preset time threshold, it is determined that the current touch operation is an invalid touch operation. That is, when the previous effective touch operation is a two-finger touch, the current touch operation has a high probability of being a two-finger touch, and when the current touch is detected as a single-finger touch, it is indicated that one finger of the user first falls on the touch pad. If the user does not move within the third preset time threshold under the condition of single-finger touch, the current touch operation can be determined to be double-finger touch, and the current single-finger touch is shielded to wait for the falling of the second finger, so that the problem of sliding and flying caused by the fact that a cursor on a screen is firstly landed by one finger is prevented. The third preset time threshold may be set according to an actual application situation, for example, the third preset time threshold is 300ms, and if the current touch operation is not moved within 300ms of the single finger falling, the current touch operation is determined to be invalid.
Further, when the touch type corresponding to the previous effective touch operation is a double-finger touch, the touch type corresponding to the current touch operation is a double-finger touch, and the click behavior occurs in the current touch operation, determining that the click behavior in the current touch operation is an invalid click behavior. That is, when the two fingers frequently and rapidly slide on the touch pad, a false pressing operation may occur, forming a clicked drag function, resulting in a cursor on the screen running off. For this scenario, if the previous effective touch operation is an effective two-finger touch, when a click behavior occurs in the current two-finger touch operation, the click behavior in the current touch operation is shielded, and the cursor is prevented from flying.
Further, to improve the error touch prevention capability, it may also be determined whether the difference between the occurrence time of the click behavior in the current touch operation and the ending time of the previous valid touch operation is within a fourth preset time threshold, and if so, it is determined that the click behavior in the current touch operation is an invalid click behavior; otherwise, determining the clicking behavior in the current touch operation as the effective clicking behavior. The fourth preset time threshold may be set according to an actual application situation, for example, the fourth preset time threshold is 500ms.
On the basis of the above schemes, if the current touch operation has click behavior, and the moving distance of the click behavior in the fifth preset time threshold is smaller than the third preset distance threshold, determining that the touch operation is the click operation. That is, when the user touches the touch pad, if the click is pressed and the moving distance within the fifth preset time threshold is less than the third preset distance threshold, the finger is considered to be pressed and not moved, and the current touch operation is determined to be the click operation. The fifth preset time threshold and the third preset distance threshold may be set according to actual application situations, for example, the fifth preset time threshold is 300ms, and the third preset distance threshold is 10px.
Optionally, in response to the movement distance of the clicking action within the fifth preset time threshold being greater than or equal to a third preset distance threshold, determining that the current touch operation is a clicking drag operation.
Optionally, after determining that the current touch operation is a valid touch operation, information related to the current touch operation may be saved, so as to facilitate a subsequent determination of the validity of the touch operation. Specifically, the first touch information and the current touch operation are saved as valid touch operations, so as to judge the validity of the new touch operation. In addition, the touch type corresponding to the current touch operation, such as a single-finger touch, a double-finger touch, or a palm touch, may also be stored.
As can be seen from the above description, to determine whether the current touch of the user on the touch pad is a false touch, first touch information corresponding to the current touch operation is acquired, where the first touch information may include first position information, and second touch information corresponding to the previous valid touch operation is acquired, where the second touch information may include second position information. And determining whether the current touch operation is the effective touch operation or not according to the second touch information and the first touch information of the previous effective touch operation. That is, when judging that the current touch operation is an effective touch operation or an ineffective touch operation, the touch information of the previous effective touch operation is referred to, so that the judgment accuracy is increased, and the false touch preventing capability is improved.
In addition, aiming at the anti-false touch processing of the touch pad when a user uses a keyboard to type, the embodiment provides a processing mode, which specifically comprises the following steps: and responding to the sixth preset time threshold value after the user presses and lifts the keys in the keyboard, and shielding the touch pad. If the sliding distance of the user on the touch pad is greater than the fourth preset distance threshold value within the sixth preset time threshold value, restarting the touch pad, and responding to the touch operation of the user. Further, after restarting the touch pad, the user may use the touch pad within a seventh preset time threshold, and after exceeding the seventh preset time threshold, disable the touch pad. The sixth preset time threshold, the fourth preset distance threshold and the seventh preset time threshold may be set according to actual application situations. For example, if the sixth preset time threshold is 300ms, the fourth preset distance threshold is 800px, and the seventh preset time threshold is 1.5s, the touch pad is disabled within 300ms after the key on the keyboard is pressed and lifted. If the sliding distance of the finger on the touch pad exceeds 800px, the processor restarts the touch pad, and the user can continuously use the touch pad within 1.5s after the touch pad is started, and continuously disable the touch pad within 1.5 s.
