Taking an application of a tablet computer as an example, fig. 3 is another exemplary application scenario diagram according to an embodiment of the present application, as shown in fig. 3, when a user uses the tablet computer 13 or picks up or puts down the tablet computer, the user may touch a touch screen of the tablet computer 13 with a hand to cause a palm error touch, so as to affect normal use of the tablet computer by the user.
Based on the application scenario, the following technical scheme is introduced in detail:
fig. 4 is a flowchart of a method for identifying a palm error touch according to an embodiment of the present application, where the method may be performed by an apparatus for identifying a palm error touch, and the apparatus may be implemented by software and/or hardware, for example: the device may be part or all of the terminal device, and the following describes a method for recognizing a palm error touch by using a chip in the terminal device as an execution main body, as shown in fig. 4, the method includes the following steps:
step S101: the method comprises the steps of obtaining the contact area and the position of each touch point on a touch surface from N touch points on the touch surface, wherein N is an integer larger than or equal to 1, and the touch surface is a touch pad or a touch screen.
The touch surface is a device capable of being operated by touch, and can be a touch pad or a touch screen, wherein the touch pad is an input device which moves a cursor by using the sliding operation of a finger on a smooth touch pad, and is widely applied to notebook computers and some portable devices, such as personal digital assistants, portable audio and video devices and the like. In addition, the touch screen is an inductive liquid crystal display device capable of receiving input signals such as a touch head, when a graphical button on the screen is touched, the tactile feedback system on the screen can drive various connecting devices according to a pre-programmed program, and the touch screen is widely applied to various intelligent devices.
When the touch surface is touched, one or more touch points may exist on the touch surface according to different touch modes, and the chip acquires the contact area of each touch point on the touch surface and the position of each touch point on the touch surface from N touch points on the touch surface, wherein N is an integer greater than or equal to 1.
Step S102: and judging whether any one touch point or any plurality of touch points conform to a preset palm model or not according to the contact area and the position of each touch point on the touch surface.
In a possible implementation manner, before determining whether any one touch point or any plurality of touch points conform to the preset palm model according to the area and the position of each touch point on the touch surface, the method further includes:
and establishing a preset palm model, wherein the preset palm model comprises a single palm model, a single palm and single finger model, a double palm model and a double palm and double finger model.
The single-palm model is a model with only one palm contacting the touch control surface, the single-palm and single-finger model is a model with the palm and fingers of one hand contacting the touch control surface, the two-palm model is a model with the palms of two hands simultaneously contacting the touch control surface, and the two-palm and two-finger model is a model with the palms and fingers of two hands simultaneously contacting the touch control surface.
After the contact area and the position of each contact point on the touch surface are obtained, whether any one touch point or any plurality of touch points conform to the preset palm model or not is judged according to the contact area and the position of each contact point on the touch surface and the established preset palm model.
Step S103: and if the touch point is in accordance with the preset palm model, determining that the touch point is mistakenly touched by the palm.
Through judgment, if the touch points conform to the preset palm model, the touch points are determined to be mistaken palm touch, exemplarily, if one touch point conforms to the single palm model, the touch point is mistaken palm touch, if two touch points conform to the single palm single finger model or the double palm model, the two touch points are judged to be mistaken palm touch, and if four touch points conform to the double palm double finger model, the four touch points are judged to be mistaken palm touch. If one or more touch points are judged to be mistakenly touched by the palm, the touch points can be marked as mistakenly touched, and the chip does not execute the operation which needs to be executed by the touch point under the normal condition, so that the condition that the user normally uses the terminal equipment due to the mistaken touch by the palm is avoided.
According to the scheme, whether any one touch point or any multiple touch points accord with the preset palm model or not is judged according to the contact area and the position of each touch point on the touch surface, whether the current touch operation on the touch surface is the palm error touch or not is judged, and the production cost is saved.
In order to determine whether any one touch point or any plurality of touch points conform to the preset palm model, different determination strategies may be selected according to the number of touch points on the touch surface, and in a possible implementation manner, fig. 5A to 5C are flowcharts of a method for identifying a palm false touch provided in another embodiment of the present application, where the method may be executed by a device for identifying a palm false touch, and the device may be implemented in a software and/or hardware manner, for example: the apparatus may be part or all of the terminal device, and the following describes a method for identifying a palm error touch by using a chip in the terminal device as an execution main body, as shown in fig. 5A, if there is a touch point on a touch surface, step S102 in the above embodiment may include:
step S201: if a touch point exists on the touch control surface, whether the touch point accords with the single-palm model or not is judged.
If a touch point exists on the touch control surface, judging whether the touch point accords with a single-palm model or not according to the area and the position of the touch point on the touch control surface, if so, judging that the touch point is mistakenly touched by a palm, and if not, judging that the touch point is normally touched by a user.
In practical operation, more than one touch point may exist on the touch surface, and optionally, as shown in fig. 5B, if two or three touch points exist on the touch surface, step S102 in the above embodiment may include:
step S202: and if two or three touch points exist on the touch control surface, judging whether the touch points conform to at least one of a single-palm model, a single-palm single-finger model and a double-palm model.
If two or three touch points exist on the touch surface, whether any one touch point accords with the single-palm model or whether any two touch points accord with the single-palm single-finger model or the double-palm model can be judged.
In addition, the embodiment of the present invention does not limit the number of touch points determined to be in accordance with the single-palm model, the single-palm single-finger model, and the two-palm model, for example, two touch points exist on the touch surface, and if the two touch points are determined to be the single-palm single-finger model, it may not be determined whether the two touch points are in accordance with the model in the two-palm model, or it may not be determined whether any of the two touch points are in accordance with the single-palm model.
Optionally, if there are four or more touch points on the touch surface, as shown in fig. 5C, step S102 in the above embodiment may include:
step S203: if four or more touch points exist on the touch control surface, whether the touch points accord with at least one of a single-palm model, a single-palm single-finger model, a double-palm model and a double-palm double-finger model is judged.
If four or more touch points exist on the touch surface, whether any one touch point accords with a single palm model or not can be judged, whether any two touch points accord with a single palm single finger model or a double palm model or not can be judged, and whether any four contact points accord with a double palm double finger model or not can be judged. For example, if there are four touch points on the touch screen, it may be selected to first determine whether the four touch points are in a two-palm and two-finger model, then determine whether any two touch points in the four touch points conform to a one-palm and one-finger model or a two-palm model, and finally determine whether any one touch point in the four touch points conforms to a one-palm model. In addition, the embodiment of the present invention does not limit the number of the touch points to determine whether the touch points conform to the single-palm model, the single-palm single-finger model, the double-palm model, and the double-palm double-finger model, for example, if there are four touch points on the touch screen, it may be determined whether any one touch point conforms to the single-palm model, it may be determined whether any two touch points conform to the single-palm single-finger model or the double-palm model, and it may be determined whether any four touch points conform to the double-palm double-finger model, or it may be determined first whether the four touch points conform to the double-palm double-finger model, and if it is determined that the four touch points conform to the double-palm double-finger model, it may be determined no longer whether the four touch points conform to the single-palm model, the single-palm single-finger model, and the double-.
According to the scheme, the preset palm model needing to be matched is selected according to the number of the touch points on the touch surface, and the accuracy rate of judging whether the current touch operation on the touch surface is palm error touch is improved.
