detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Embodiment one

Figure 1 is a flow chart of a method for preventing false touches provided by Embodiment 1 of the present invention. This embodiment is applicable to prevent false touches when operating a smart terminal with one hand. This method can be implemented by a smart terminal with a touch screen Such as smart phones, tablet computers, etc., as shown in Figure 1, the method for preventing false touches specifically includes the following steps:

Step 110, determine the anti-mistouch area according to the holding state of the left and right hands.

Wherein, the false touch prevention area may be located on the left edge, the right edge, the lower edge or the upper edge of the screen. The false touch prevention area corresponds to the way the user holds the smart terminal. For example, when the user holds the smart terminal horizontally, the false touch prevention area may be the left edge or the right edge of the screen. When the user holds the smart terminal vertically, the false touch prevention area may be the upper edge or the lower edge of the screen. The left edge, right edge, lower edge or upper edge of the smart terminal can be determined according to the relative position in the schematic diagram of the terminal shown in FIG. 2 , but is not limited to the definition of this edge. The width of the edge shielding area can be any fraction between 0-1/8 of the length of the wide side of the smart terminal.

In one application scenario, when the user holds the smart terminal with the right hand or the left hand, the smart terminal automatically recognizes the holding state to determine the position of the edge shielding area. For example, if the holding state is the right hand holding state, then determine the right edge of the screen as the anti-mistouch area, and if the holding state is the left hand holding state, then determine the left edge of the screen as the anti-mistouch area. Or users can manually set the smart terminal to the default holding state according to their own habits of using the smart terminal. For example, left-handers can set the smart terminal to the left-hand holding state. The edge is determined as an anti-mistouch area.

Preferably, step 110 includes: if the holding state is the right hand holding state, determining the right edge of the screen as the false touch prevention area. Fig. 2a is a schematic diagram of a holding state of the right hand in Embodiment 1 of the present invention. As shown in Fig. 2a, the smart terminal 210 is in the vertical screen working state, and the gravity acceleration sensor can judge that the smart terminal is currently in the horizontal screen Or vertical screen working state. When only the right hand is holding the smart terminal and operating it, and the thumb of the right hand is touching the screen, the thenar part of the right hand can easily touch the right edge of the touch screen by mistake, and the right edge needs to be determined as the right shield Edge 211. In the actual application scenario, when the user only uses the right hand to operate the smart terminal, when the thumb of the right hand taps the screen, the smart terminal will rotate along the bottom right with the action of the thumb click, and the gravity acceleration sensor in the smart terminal will respond according to the sensing The motion direction of the smart terminal is detected, and it is judged that the smart terminal is held in the right hand at this time, so that the right edge of the screen is determined as the anti-mistouch area. After the right edge of the screen is determined as the anti-mistouch area, when the user only uses the right hand to operate the smart terminal, it can effectively prevent false touches on the right edge of the screen.

Step 110 further includes: if the holding state is the left-hand holding state, determining the left edge of the screen as an anti-mistouch area. Figure 2b is a schematic diagram of another holding state in Embodiment 1 of the present invention, which is the holding state of the left hand. As shown in Figure 2c, the smart terminal 210 is in a vertical screen working state, when only the left hand holds the smart terminal and operates it , when the thumb of the left hand clicks on the screen, the thenar part of the left hand is easy to mistakenly touch the left edge of the touch screen, and the right edge needs to be determined as the left shielding edge 212 . In the actual application scenario, when the user only uses the left hand to operate the smart terminal, when the thumb of the left hand taps the screen, the smart terminal will rotate along the lower left side with the action of the thumb click, and the gravity acceleration sensor in the smart terminal will be based on the sensing According to the movement direction of the intelligent terminal, it is judged that the intelligent terminal is in the state of being held by the left hand at this time, so as to determine the left edge of the screen as the anti-mistouch area. After the left edge of the screen is determined as the false touch prevention area, when the user only uses the left hand to operate the smart terminal, it can effectively prevent false touches on the left edge of the screen.

Figure 2c is a schematic diagram of one-handed operation of the intelligent terminal in the horizontal screen state in Embodiment 1 of the present invention. , the thenar portion of the palm is likely to touch the lower edge of the touch screen by mistake, and it is necessary to determine the lower edge as the lower shielding edge 213 . In an actual application scenario, the acceleration of gravity sensor will sense that the smart terminal is currently in a horizontal screen working state, so as to determine the lower edge as an anti-mistouch area. After the lower edge of the screen is determined as the false touch prevention area, when the user operates the smart terminal with one hand (left hand or right hand), it can effectively prevent false touches to the lower edge of the screen.

Step 120, detecting a touch operation input by the user on the screen.

Wherein, the screen includes the false touch prevention area. The screen also includes a non-unintended touch area. The touch operation input by the user on the screen may be detected through detection methods such as resistance type, capacitance sensing type, infrared type and surface acoustic wave type. When the user taps the screen with a finger to perform a click operation, the detected touch operation is the contact surface of the user's finger and the screen, and the coordinates of the touch position can be determined according to the contact surface.

Step 130, if it is detected that part of the contact surface corresponding to the touch operation is within the false touch prevention area and part is outside the false touch prevention region, then determine whether to perform shielding according to the shape of the contact surface.

Wherein, the shape of the contact surface may be palm-shaped or contain palm prints. In this application scenario, the implementation method of determining whether to perform shielding according to the shape of the contact surface can be, if the shape of the contact surface is palm-shaped and the area of the contact surface is larger than the preset area or the contact surface contains palm prints, then determine to perform shielding .

Preferably, step 130 includes: if the shape of the contact surface is palm-shaped and the area of the contact surface is greater than a preset area or the contact surface contains palm prints, then determine to perform shielding. 3 is a schematic diagram of the contact surface part in the anti-mistouch area in the embodiment of the present invention. As shown in FIG. Outside the right shield edge area. Wherein, the preset area may be the maximum value of the touch area in historical records under normal touch screen conditions when the user uses the smart terminal, and the preset area may be set according to different users.

Optionally, the palm-shaped feature is a shape whose width gradually decreases from the edge of the screen to the center of the screen.

Optionally, when the contact surface is a palm, the texture feature of the contact surface is palm prints. Compared with the curved arc of the fingerprint texture, the palmprint texture tends to be more straight. The palm prints on the thenar are horizontal and vertical checkered patterns

In this application scenario, when the shape of the contact surface is palm-shaped and the area of the contact surface is greater than the preset area, the process of determining the shielding may be that the smart terminal first recognizes the touch operation, and then judges the size of the contact surface for the touch operation. The shape is palm-shaped, and the area of the contact surface is larger than the preset area, and finally the touch operation is shielded. When the contact surface contains palmprints, the process of determining shielding may be that after the smart terminal recognizes the touch operation, it identifies whether the lines on the contact surface are palmprints, and if it is, shields the touch operation. If the contact surface is in the shape of a finger or contains a fingerprint, then the contact surface is made accordingly. Specifically, all or part of the contact surface may be located in the false touch prevention area.

In this embodiment, the anti-mistouch area is determined according to the holding state of the left and right hands, and the touch operation input by the user is detected on the screen. Outside the area, it is determined whether to perform shielding according to the shape of the contact surface. In the prior art, the way to prevent false touch is to shield the touch signal of the fixed edge. When the contact surface operated by the user contains a shielded area, the user operation will be shielded. This method will shield the non-mistouch operation. The recognition rate of touch operation is low. The false touch prevention method provided by the embodiment of the present invention can determine the false touch prevention area according to the grip state of the user's left and right hands. The shape of the touch screen determines whether to shield, which can effectively prevent false shielding of non-false touch operations and improve the recognition rate of touch operations. In addition, for the case of non-palm false touch, that is, when the finger taps the edge area of the screen, since the shape of the contact surface corresponding to the finger tap operation is different from the shape of the palm, it can respond to all or part of the finger tap operation located in the anti-false touch area. Improve the operation response efficiency of the false touch prevention area.

Fig. 4 is a flow chart of another method for preventing false touch provided by the embodiment of the present invention. Based on the above embodiment, as shown in Fig. 4, step 130 includes:

Step 131 , if the touch operation is a sliding operation, acquire the coordinates of the starting point of the sliding operation.

Wherein, the sliding operation may be a continuous touch operation with a certain motion track, and the motion track may be a straight line, an S-shaped curve, or a curve of other shapes. The coordinate value may be a relative coordinate value determined according to the preset coordinate origin of the smart terminal, and the coordinate value may reflect the area of the point on the screen. In this application scenario, the method of obtaining the coordinates of the starting point of the active operation may be, after the smart terminal recognizes that the touch operation is a sliding operation, recognizes the corresponding starting point of the sliding operation, and then obtains the coordinate value corresponding to the starting point, according to The coordinate value determines the screen area where the start position of the sliding operation is located.

Step 132 , if the coordinates of the starting point are within the anti-mistouch area, then determine whether to shield the touch operation according to the historical operation record or the validity of the sliding operation.

Among them, the historical operation record can be whether the sliding operation has occurred within a preset time period, and the preset time period can be set to any number of days in a week, for example, the preset time period is 3 days, if the sliding operation occurs within three days If the smart terminal considers that the sliding operation is not a false touch, it will not block it; or the number of times the sliding operation has occurred in the previous operation, for example, if the operation has occurred 3 times in the previous operation, then this The sliding operation that occurs for the first time will be judged by the smart terminal as not a false touch, and will not be blocked. The effectiveness of the sliding operation may be that the sliding operation can cause the screen to respond and perform corresponding actions. Exemplarily, in a picture page, a left or right swipe operation can cause the picture to switch, and at this time the left or right swipe operation is valid, while the up or down swipe operation does not cause Any movement of the screen, swiping up or down is invalid. In this application scenario, the method of determining whether to shield the touch operation according to the validity of the sliding operation may be: if the sliding operation is valid on the corresponding page, then the sliding operation is not blocked; if the sliding operation is valid on the corresponding page is invalid, the sliding operation is blocked.

In the technical solution provided by this embodiment, if the touch operation is a sliding operation, then obtain the coordinates of the starting point of the sliding operation, and if the coordinates of the starting point are located in the anti-mistouch area, then determine according to the historical operation records or the validity of the sliding operation Whether to block touch operations. Determine whether to shield the sliding operation whose starting point is in the shielded area, so as to prevent it from being recognized as a false touch operation instead of a false touch operation, and improve the recognition rate of touch operations.

Preferably, the false touch prevention method further includes: if within a preset period of time, multiple false touches occur outside the false touch prevention area and the positions of the false touches are the same, adjusting the false touch prevention area according to the positions of the multiple false touches.

Wherein, the preset duration can be any duration in 1-3 hours. In an actual application scenario, the user performs the same operation at the same position on a certain interface of a certain software multiple times within a preset period of time, and the position is outside the preset shielded area, and the smart terminal recognizes that the position has multiple false touches . In order to prevent accidental touches from affecting the normal execution of the software, the area where the position is located is adjusted to the preset shielding area. Optionally, the user manually sets the false touch location as the preset shielding area according to the false touch location that often occurs when operating the smart terminal. The preset shielding area and the false touch prevention area at the edge form a new edge shielding area.

In the technical solution provided by this embodiment, if there are multiple false touches outside the false touch prevention area within the preset time period and the positions of the false touches are the same, the false touch prevention area is adjusted according to the positions of the multiple false touches. The anti-mis-touch area can be flexibly adjusted according to the position of mis-touch, and the edge shielding area can be dynamically adjusted to reduce the number of mis-touches and improve user experience.

Step 220 , detecting a touch operation input by the user on the screen.

Step 230, when it is detected that the user inputs a touch operation, acquire a contact surface corresponding to the touch operation.

Step 240 : If the contact surface corresponding to the touch operation is partly within the false touch prevention area and partly outside the false touch prevention area, obtain the shape and texture of the contact surface and calculate the area of the contact surface.

Step 250 , if the shape of the contact surface is palm-shaped or the area of the contact surface is larger than a preset area or the contact surface contains palmprint texture, shield the touch operation.

Step 260: If the shape of the contact surface is finger-shaped, the area of the contact surface is smaller than the preset area, and the contact surface contains fingerprint texture, respond to the touch operation.

Optionally, when a user wears gloves and performs a touch operation with a finger, the contact surface cannot sense fingerprints or palm prints. At this time, the shape of the contact surface is finger-shaped, and the area of the contact surface is smaller than a preset area.

Step 270 , if multiple false touches occur outside the false touch prevention area within the preset time period and the positions of the false touches are the same, then adjust the false touch prevention area according to the positions of the multiple false touches.
