Description

Method for operating touch screen terminal, control device and touch screen terminal

The present invention relates to the field of mobile communication technologies, and in particular, to a touch screen terminal, a control device, and a working method of a touch screen terminal. Background technique

In recent years, with the continuous development and popularization of smart phones, users have gradually become accustomed to using touch screens instead of keyboards to operate mobile phones. The intuitiveness and ease of use of mobile phone touch screens are becoming more and more accepted by users.

There are many types of touch screens, such as resistive touch screens, capacitive touch screens, infrared touch screens, surface acoustic wave touch screens, and the like. Currently, on the market, the most widely used mobile phone products are resistive touch screens and capacitive touch screens. Among them, the resistive touch screen is basically a film-plus-glass structure, and the adjacent side of the film and the glass is coated with a nano-indium tin metal oxide (ITO) coating, and the ITO has good electrical conductivity and transparency. When the touch operation is performed, the ITO under the film contacts the ITO on the upper layer of the glass, and the corresponding electrical signal is transmitted through the inductor, sent to the processor through the conversion circuit, and converted into X and Υ values on the screen by calculation, thereby completing the point. The selected action is presented on the screen; the capacitive touch screen is a layer of transparent special metal conductive material on the surface of the glass. When the finger touches the metal layer, the capacitance of the contact changes, causing the frequency of the oscillator connected to it to change, and the touch position can be determined by measuring the frequency change. The capacitive touch screen is plated with narrow electrodes on all four sides of the touch screen to form a low voltage alternating electric field in the conductive body. When the screen is touched, due to the electric field of the human body, a coupling capacitor is formed between the finger and the conductor layer, and the current from the four electrodes flows to the contact, and the current intensity is proportional to the distance from the finger to the electrode, and the controller located behind the touch screen is The ratio and strength of the current are calculated, and the position of the touch point is accurately calculated. In the process of using the touch screen of the mobile phone to operate on the interface, no matter what kind of touch screen is used, the user often encounters a problem of misoperation, for example: the original user wants to click the icon eight, but after clicking, the reaction is with the icon A. Icon B close to each other; or, the icon A that the user wants to click is always missed, and the user can only click again or repeatedly, which not only delays the time, but also affects the user experience. The reasons for this problem: First, because the resolution of the touch screen is high or low, the smaller the icon, the more difficult the icon in the point is, and the quality of the touch screen is also uneven. Second, because the user's finger also has Large and small, users with large fingers can easily miss the position they need when using a small touch screen. In response to this problem, the current smart phone does not have an effective zoom-in operation on the interface menu, but for the Internet browsing, or when reading text, the entire screen can be enlarged, but this amplification has some drawbacks, because it is an overall enlargement, so When the user operates, it is often necessary to adjust the area to be enlarged by the up and down and left and right sliding adjustments, and after the operation of the enlarged area is completed, the user is likely to need to resize the entire picture to the original size, adding user operation. The cumbersomeness. Even if the system has the function of enlarging the entire font, the degree of font enlargement is limited, and the size of the font has a great relationship with the visual beauty.

The embodiments of the present invention are further described in detail below with reference to the accompanying drawings. Embodiment 1:

As shown in FIG. 1, the working method of the touch screen terminal of the embodiment includes the following steps: Step 101: Acquire a critical intersection area of the corresponding icon according to the icon distribution displayed on the screen;

Step 102: Obtain location information of a user touch point on the screen;

Step 103: Determine, according to the location information, whether the touch point falls within a critical intersection area of the corresponding icon, if step 105 is performed, if not, execute step 104;

Step 104: directly respond to the location information corresponding icon;

Step 105: Display an icon included in the critical intersection area where the touch screen point falls. In the working method of the touch screen terminal of the embodiment, when the touch point does not fall within the critical intersection area of the corresponding icon, a plurality of situations may be included. For example, step 104 may also include: Do any response or other preset processing.

The working method of the touch screen mobile terminal of the embodiment introduces the concept of a critical intersection area, and acquires an intersection area of the entire screen. When the touch screen reports the touch point location information of the user touching the screen to the mobile terminal operating system, the mobile terminal operates. The system judges whether the touch point is in the critical intersection area according to the location information, and determines whether the icon included in the intersection area is displayed and presented to the user, facilitating the user's click operation.

In the above step 101, a critical intersection area of the corresponding icon is obtained, where the corresponding icon may include: all icons on the display screen, or partial icons on the display screen; the corresponding icons are determined according to the distribution of the display icon icons, For example, in the user interface of the mobile phone (UI, User Interface), the icon is arranged in a nine-square grid. In this case, the critical intersection area of all the icons on the UI needs to be obtained; however, if the arrangement on the UI of the mobile phone is irregular, as shown in FIG. 2, The icon D is far away from the icons A, B, and C, so the possibility of causing the user to operate incorrectly is relatively small. In this case, only the critical intersection area of the icons A, B, and C can be obtained, and the corresponding icon is only the icon eight. B, C. In the actual operation, it is determined whether the critical intersection area of the icon needs to be acquired by determining the coordinate distance between adjacent icons. If the coordinate distance is greater than the preset threshold, the critical intersection area of the icon is not obtained, and if the coordinate distance is less than the pre-predetermined Set the threshold to get the critical intersection area of the icon.

The icon included in the critical intersection area in which the touch screen point falls in the above step 105 is displayed:

The display in this embodiment may also include: displaying only the icons included in the critical intersection area on the entire interface.

The working method of the touch screen terminal of this embodiment does not enlarge the entire screen as a whole, and the zooming is targeted, and the operation is simple and clear.

As shown in FIG. 3, the working method of the touch screen terminal in this embodiment is to the touch screen in step 105. After the icon included in the critical intersection area of the point is displayed (including the enlarged display), the method further includes: Step 106: Acquire the position information of the touch screen point of the user on the screen again;

Step 107: Select the corresponding zoom icon and respond according to the location information.

The key to the working method of the touch screen mobile terminal in the embodiment of the present invention is that the display screen is first divided according to the area where the function icons are distributed and a plurality of critical intersection areas are obtained, and the critical intersection area refers to various functions on the display screen. In the case where the icons are distributed, the areas between the adjacent icons (which may include a certain part of the icon itself) that are prone to misoperation are divided and acquired as separate functional areas. On the actual mobile terminal display, such as the area where the mobile phone display is most prone to misoperation, is the area between two adjacent icons.

In the above step 101, obtaining the boundary intersection area of the corresponding icon according to the distribution of the icons displayed on the screen includes:

Obtaining a critical intersection according to the center coordinate value of the icon itself and the adjacent icon, the icon itself, and the size of the adjacent icon;

Alternatively, the critical intersection region is obtained according to the coordinate value of the icon on the same horizontal or vertical line on the adjacent boundary of the adjacent icon, the icon itself, and the size of the adjacent icon.

The specific process of obtaining the critical intersection area according to the central coordinate value of the icon itself and the adjacent icon, the icon itself and the size of the adjacent icon in the embodiment includes:

When the icon is in the same horizontal direction as the adjacent icon, the critical intersection area is set to a rectangle whose center is (xl+x2)/2, the horizontal range is |xl-x2|, and the vertical range is between bl and b2. Smaller value

When the icon is in the same vertical direction as the adjacent icon, the critical intersection area is set to be a rectangle whose center is (yl+y2)/2, the vertical range is |yl-y2|, and the horizontal range is between a1 and a2. Smaller value. In order to explain in detail the process of obtaining the critical intersection region in this embodiment, two algorithms are proposed in this paper, one for the critical intersection region acquisition algorithm on the UI, and the other for the input algorithm interface critical intersection region acquisition algorithm, patent protection The algorithms include but are not limited to these two algorithms. First, the UI critical intersection acquisition algorithm assumes that the resolution of the touch screen is a*b, a is the horizontal dimension, b is the vertical dimension, and icon A is a function icon on the interface, which is easy to malfunction with icon A. The icon is assumed to be icon B. The algorithm sets the icon A to be misinterpreted only by the adjacent icons in the horizontal or vertical direction around it, and each critical intersection contains only two function icons, which are two closely adjacent icons. Therefore, the icon B is in the vertical or horizontal adjacent direction of the icon A, the icon A and the icon B are located in the same critical intersection area, the central coordinate of the support icon A is (xl, yl), and the icon size is ll * nl, the icon B The center coordinates are ( x2, y2 ) and the icon size is 12*n2. ^^ If icon A and icon B are in the same horizontal direction, the ordinates yl and y2 are the same, the algorithm only needs to consider the horizontal area, (xl+x2)/2 is the center of the critical intersection area, and the critical intersection area is a rectangular shape. , its horizontal range is |xl-x2|, its vertical range is the smaller value between nl and η2; if the icon Α and the icon Β are in the same vertical direction, the abscissa xl and x2 are the same, the algorithm only needs to consider the vertical The region, (yl+y2)/2 is the center of the critical intersection, and the critical intersection is a rectangular shape with a vertical range of |yl-y2|, and its horizontal range is a small value between 11 and 12, as shown in the figure. In the figure shown in Fig. 4, the dotted line frame is the critical area of icon A and icon B; the second type is the algorithm for obtaining the critical intersection area of the input method interface, assuming that icon A and icon B are two input button icons adjacent to the horizontal direction, the icon The horizontal lengths of A and icon B are xl and x2, respectively, and the vertical lengths are yl and y2, respectively. Since there is no adjacent blank area between icon A and icon B, the critical intersection area is covered by a part of icon A and icon B itself. Composition, set between icon A and icon B The horizontal intermediate position is 0, with 0 as the center, and the half of the horizontal dimension of the icon A and the icon B connected to 0 is the horizontal length of the critical intersection area, that is, the horizontal size of the critical intersection area is (xl+x2) /2. The vertical dimension is the smaller of yl and y2.

The working method of the touch screen terminal of this embodiment can also be performed according to icons and adjacent icons. The coordinate values on the same horizontal or vertical line on the adjacent border, the icon itself, and the size of the adjacent icon acquire the critical intersection region. Taking the mobile phone UI as an example, the coordinates of the points & and b on the icon A and the icon 8 can be obtained first, and the points a and b are two points on the same level on the adjacent boundary, where a ( xl, yl ), b ( X2, y2), and then obtain the dimensions of icon A and icon B as: ll *nl, 12*n2; as shown in Fig. 5, the critical intersection area can be set to a rectangle, and (xl+x2)/2 is a critical intersection area. Center, the critical intersection is a rectangular shape with a horizontal range of |xl-x2| and a vertical range of smaller values between nl and n2. Similarly, the critical intersection area between the icon Α and the icon C can be obtained. As shown in FIG. 5, the dotted line area 1 between the icon A and the icon B is a critical intersection area between the icon A and the icon B, and the icon A and The dotted line frame area 2, the area 4, and the area 3 between the icon C, the icon B and the icon D, the icon C and the icon D are the respective critical intersection areas.

As shown in FIG. 6, the user selects the function application icon on the UI of the touch screen mobile phone as an example to illustrate the working method of the touch screen terminal in this embodiment:

Step 200: The touch screen mobile phone acquires a critical intersection area of the corresponding icon according to the function application icon distribution displayed on the screen (for example, an algorithm of the above-mentioned central coordinate may be used to obtain the critical call intersection area);

Step 201: The user clicks on the touch screen of the mobile phone to select a desired function application icon;

Step 202: Obtain a coordinate value of a position where the user clicks on the screen;

Step 203: Determine whether the coordinate value is in the critical intersection area, if otherwise, perform step 204, if yes, execute step 205;

Step 204: directly respond to the icon corresponding to the coordinate value (such as opening the function application);

Step 205: Enlarge the icon in the critical intersection area for the user to select again; Step 206: The user selects the desired function application icon again by clicking the mobile phone touch screen; Step 207: Acquire the position coordinate value of the user clicking the screen again;

Step 208: directly select the zoom icon corresponding to the coordinate value and respond. The icon in this embodiment is a function application icon on the UI or a character icon on the input method interface.

The working method of the touch screen terminal in the embodiment of the invention effectively solves the contradiction between the low screen resolution and the large finger of the user, the operation steps are simple, the efficiency of the user's effective click is improved, and the user experience is improved. Compared with the current overall interface scaling, the advantages are: First, the current overall zooming mechanism is basically used to browse text or browse web pages, and this method can be applied to any interface; secondly, this operation is simple and effective, basically It can be guaranteed that there will be no accidental clicks, and the method of enlarging the whole interface requires the user to re-move the interface for icon confirmation. After clicking the icon, the entire interface needs to be reduced, and the operation is too cumbersome.

In the working method of the touch screen terminal of the embodiment, since the determination of the critical intersection area is added in the flow of the general touch screen operation, the actual intention of the user can be more accurately determined, and in terms of the complexity of the operation, compared with the current The overall zooming scheme makes the operation simpler and does not require zooming in and out to position the icon. In terms of the feasibility of implementation, a good algorithm can ensure the rationality of the critical intersection area acquisition, and in the software implementation scheme, the system can give a unified application program interface (API), and the interface that needs to be obtained by using the critical intersection area. , just call the system's unified API, and pass the corresponding parameters.
