Description

Method and system for preventing or reducing misoperation of touch screen

Technical Field

The invention relates to the field of communication, in particular to a method for preventing or reducing misoperation of a touch screen, and a system capable of realizing the method.

Background

Touch screen (also called touch screen or touch panel) is an inductive liquid crystal display device capable of receiving input signals such as touch, when touching graphic buttons on the screen, the touch feedback system on the screen can drive various connecting devices according to a pre-programmed program, and can replace a mechanical button panel and produce vivid video and audio effects by the liquid crystal display picture. As a latest input and display device, the touch screen is the simplest, convenient and natural man-machine interaction mode at present. The multimedia interactive device gives the multimedia a brand-new appearance and is a brand-new multimedia interactive device with great attractiveness. The touch screen has wide application in the intelligent terminal.

The touch screen consists of a touch detection component and a touch screen controller; the touch detection component is arranged in front of the display screen and used for detecting the touch position of a user and sending the touch position to the touch screen controller after receiving the touch position; the touch screen controller is mainly used for receiving touch information from the touch point detection device, converting the touch information into touch point coordinates and sending the touch point coordinates to the CPU, and meanwhile, the touch screen controller can receive and execute commands sent by the CPU.

However, the touch screen has a disadvantage in that it is easily misoperated. Particularly, the portable intelligent terminal with the touch screen is easy to operate by mistake. For this reason, some proposals have been made to prevent or reduce the occurrence of the malfunction of the touch panel.

The Chinese patent application with the application publication number of CN104375761A and the application publication date of 2015.02.25 discloses a method and a system for preventing misoperation of a touch screen mobile phone, wherein touch points triggered on the touch screen are received in real time, and the effective touch area value of the touch points is calculated; the calculated effective touch area value of the touch point is compared with a preset touch area threshold value, if the effective touch area value of the touch point is smaller than the touch area threshold value, the touch screen performs corresponding operation according to a control instruction triggered by the touch point, otherwise, the current trigger operation is inhibited, so that the touch area value of the trigger operation is analyzed according to the difference between the touch area triggered by the error and the touch area of the finger, whether the trigger operation is the error trigger is judged, and when the trigger operation is the error trigger operation, the operation is inhibited, the error trigger of the touch screen is effectively prevented, the electric quantity can be effectively saved, the accidental increase of information charges can be avoided, and convenience is brought to a mobile phone user with the touch screen.

The application has a drawback in that if the effective touch area value of the touch point is smaller than the touch area threshold, and the operation is indeed a malfunction, such malfunction cannot be suppressed or cancelled. Particularly, when the touch screen has a one-key help calling function, misoperation of the one-key help calling obviously brings adverse effects.

At present, many intelligent terminals, especially mobile intelligent terminals, more especially mobile intelligent terminals of touch screens have a one-key help calling function. The user clicks the one-key help calling button to realize one-key help calling. One-key help calling is convenient and quick. But because the touch screen is susceptible to malfunction. The one-key help calling is initiated under the condition of one-key help calling by misoperation (in many cases, the misoperation is not noticed, and if the mobile intelligent terminal is placed in a bag, the misoperation is caused by collision), so that social resources are wasted.

Disclosure of Invention

The first aspect of the present invention is to provide a method for preventing or reducing the occurrence of a misoperation of a touch screen, so as to solve the technical problem that the misoperation in the prior art cannot be cancelled.

The present invention solves the above technical problems by the following technical solutions, and achieves the object of the first aspect of the present invention.

A method for preventing or reducing misoperation of a touch screen is characterized by comprising the following steps:

A) if the touch screen touches the control, obtaining the touch point coordinate at the beginning when the touch screen starts to be touched;

B) when the touch screen stops being touched, obtaining the coordinates of the touch point when the touch screen stops being touched;

C) calculating the absolute value of the displacement value of the contact at the starting time and the contact at the stopping time, and judging whether the absolute value of the displacement value is larger than or equal to a set value or not; if yes, the operation corresponding to the touched control is not executed; if not, the subsequent steps are carried out.

The judgment of touching starting and touching stopping is the conventional function of the touch screen, is the standard interface of the touch screen, and is regarded as starting when the touch screen is clicked, and regarded as stopping when the touch screen is left, which is not described herein.

The control is a button, menu or icon, preferably a button.

The technical scheme is mainly applied to the condition that the user's finger mistakenly points the control of the touch screen. The touch screen control method has the advantages that after the user clicks the control of the touch screen by the finger, the user can slide the finger on the touch screen (such as upward sliding) under the condition that the user finds that the point is a wrong point, and then the misoperation can be cancelled.

In some cases, the touch time on the touch screen is very short, which is basically a malfunction. In order to further prevent or reduce such an erroneous operation, the following technical means is proposed on the basis of the first technical means:

in the step A), detecting a starting time point when the touch screen starts to be touched; in the step B), detecting a stopping time point when the touch screen stops being touched;

the subsequent steps include:

D₁) Calculating a time point difference value between the starting time point and the stopping time point, and judging whether the time point difference value is smaller than or equal to a preset time period value, if so, not executing the operation corresponding to the touched control; if not, executing the operation corresponding to the touched control.

In some cases, the touch to the touch screen is very slight, which is basically a malfunction. In order to further prevent or reduce such an erroneous operation, the following technical means is proposed on the basis of the first technical means:

detecting a pressure value while the touch screen is touched;

the subsequent steps include:

D₂) Comparing the maximum value of the pressure values, judging whether the maximum value of the pressure values is smaller than or equal to a preset pressure value, if so, not executing the operation corresponding to the touch of the control; if not, executing the operation corresponding to the touched control.

In some cases, the touch area of the touch screen is small or large, which is basically a malfunction. In order to further prevent or reduce such an erroneous operation, the following technical means is proposed on the basis of the first technical means:

detecting a touch area value during the touch of the touch screen;

the subsequent steps include:

D₃) Comparing the maximum value of the touch area value, judging whether the maximum value of the effective touch area value exceeds the range of a preset touch area value, if so, not executing the operation corresponding to the touched control; if not, executing the operation corresponding to the touched control.

In order to comprehensively prevent or reduce the misoperation of short touch time, slight touch, small touch area or large touch area on the touch screen on the basis of the first technical scheme. On the basis of the first technical scheme, the following technical scheme is proposed:

in the step A), detecting a starting time point when the touch screen starts to be touched;

in the step B), detecting a stopping time point when the touch screen stops being touched;

detecting a pressure value while the touch screen is touched;

detecting a touch area value during the touch of the touch screen;

the subsequent steps include:

D₄) Calculating a time point difference value between the starting time point and the stopping time point, and judging whether the time point difference value is smaller than or equal to a preset time period value or not;

comparing the maximum value of the pressure values, and judging whether the maximum value of the pressure values is smaller than or equal to a preset pressure value or not;

comparing the maximum value of the touch area value, and judging whether the maximum value of the touch area value exceeds the range of a preset touch area value;

if at least one of the three judgments is yes, the corresponding operation of touching the control is not executed; if the three judgments are negative, executing the operation corresponding to the touched control;

or if the three judgments are yes, the operation corresponding to the touched control is not executed; if at least one of the three items is judged to be negative, the corresponding operation touched by the control is executed;

or if the three items judge that at least two items are judged to be yes, the corresponding operation that the control is touched is not executed; and if the three items judge that at least two items are judged to be negative, the corresponding operation touched by the control is executed.

The preset time period value, the preset pressure value and the preset contact area value range should not be fixed in a reasonable sense. For example, if the user is very weak and needs first aid, if the preset time period value is not reduced, the preset pressure value is not reduced, or the minimum value and the maximum value of the preset touch area value range are not reduced, it is not favorable for the user to call for help. In a preferred technical scheme, the preset time period value, the preset pressure value and the preset touch area value range are adjusted according to a monitoring result of wearable health equipment carried by a user.

On the basis of any one of the above technical solutions, preferably, the control is a one-key distress call button. Specifically, the mobile intelligent terminal is a virtual one-key distress call button of the touch screen.

According to the method for preventing or reducing the occurrence of the misoperation of the touch screen, when a user clicks a control (the control is a button, a menu or an icon, preferably the button, and further preferably the button for calling for help) of the touch screen by a finger, the user can slide the finger (such as sliding upwards) on the touch screen under the condition that the user finds that the control is a wrong point, so that the misoperation can be cancelled.

calculating a time point difference value between the starting time point and the stopping time point, and judging whether the time point difference value is smaller than or equal to a preset time period value or not;

comparing the maximum value of the pressure value, and judging whether the maximum value of the pressure value is less than or equal to a preset pressure value or not;

In a preferred technical scheme, the preset time period value, the preset pressure value and the preset touch area value range are adjusted according to the monitoring result of the wearable health equipment carried by the user.
