Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a detection processing apparatus and method. BACKGROUND OF THE INVENTION New consumer electronic products such as smart phones have made touch screens popular. Handheld terminals such as touch-screen phones are generally not large in size due to their portability, so that output errors may occur when inputting information. For example, in the state of inputting information, the size of the keys displayed on the virtual keyboard is small. For example, in the IPHO E 3GS mobile phone, the size of the keys displayed in the virtual keyboard in the vertical screen state is 3.6 mm*5.3 mm (length * width). The size of the button displayed on the virtual keyboard in the horizontal screen state is 4.3mm*3.8mm (length*width), and research shows that 9.2mm is the smallest size that the finger can easily click on the target. Therefore, touch the virtual keyboard with the finger on the touch screen. Input, there is a possibility of a click error. The reason for this problem is that for the touch screen, if a related operation is required, it is necessary to touch the screen, which results in limitation of the input of the touch screen. In the related art, some solutions are proposed for the problem. For example, FIG. 1 is a schematic diagram of a virtual keyboard input method in the related art. As shown in FIG. 1 , after the user touches the virtual keyboard area, the screen will press a letter or a number corresponding to the button. The enlarged display is for the user to confirm. However, the button information of the zoom-in prompt cannot be touched. At this time, the user can only cancel the current input by rewinding and re-enter, which reduces the efficiency of the input. For example, FIG. 2 is a schematic diagram of another virtual keyboard input method in the related art. As shown in FIG. 2, after the user touches the virtual button area, an enlarged prompt screen corresponding to the button appears for the user to confirm, but if the user finds If the enlarged information is not the desired button, the touch area is incorrect. At this time, the button can be kept pressed for a long time, and the lower selection list of the virtual keyboard can be displayed. FIG. 3 is a lower selection list of the virtual keyboard shown in FIG. As shown in FIG. 3, the virtual keyboard displays a list of buttons near the button for the user to select, but when the lower selection list is performed, it is already a second judgment on the input, which also reduces the input efficiency. The above solution does not change the nature of the touch screen when the input information is changed. When the size of the touch screen is limited, input errors may still occur. SUMMARY OF THE INVENTION In view of the fact that the above-mentioned scheme does not change the input information in the prior art, the touch screen still needs the essence of touching the screen.

The virtual keyboard with the proximity detecting unit provided by the embodiment includes: a proximity detecting unit 72 for detecting the proximity of the human input medium above the virtual keyboard area, and the sensing layer of the virtual keyboard area of the touch screen is formed by the vertical and horizontal array of sensing coils. Sensing units, each sensing unit can sense and confirm a button position. The display unit 74 is enlarged, when the sensing intensity of a certain adjacent detecting unit reaches a certain range, that is, the input medium and the touch screen are detected. When the distance is less than a certain threshold, the button included in the proximity detecting unit is displayed enlarged in the area and above the button. The touch detecting unit 76 detects and determines the touch position information through the sensing layer to obtain corresponding input information, and the terminal can perform a corresponding action according to the input information. The virtual keyboard in this embodiment can sense the position of the button when the user's input medium, such as an electromagnetic pen, is close to the touch screen, and enlarge the button area, so that the user can touch in the enlarged display button, eliminating the small The area button has an error during input, and the input efficiency is improved by modifying the rollback operation. In the present embodiment, a flow chart of a method for inputting through a virtual keyboard with a proximity detecting unit is provided. FIG. 8 is a flow chart of a method for inputting through a virtual keyboard with a proximity detecting unit according to an embodiment of the present invention, as shown in FIG. As shown, the process includes the following steps: Step S802: When the user enters the information input state, the virtual keyboard with the proximity detecting unit is turned on, and the induction coil is installed under the touch screen virtual keyboard, and the sensing layer is formed by the criss-crossing induction coil array. Multiple sensing units. When the user's input medium (for example, a touch pen) is close, the electromagnetic field may be changed by changing the spatial distance between the touch screen and the touch screen on which the induction coil is mounted. In step S804, when the input medium is close to the touch screen, the electromagnetic field of the induction coil changes. Therefore, a threshold can be set, when the sensing intensity reaches the threshold, the position of the contact is calculated, and a signal is sent; Step S806, the virtual keyboard detects the signal sent in step S802, the information is sent to the input software system, and the button is This area and the top of the button are enlarged. For example, 1.5 times or 2 times of magnification, specifically, according to the actual display pixel and display size of the display screen, an appropriate magnification may be selected, so that the keys in the enlarged control input area are convenient for the user to select accurately. In practical applications, since the position of the button has a certain deviation from its corresponding display area, when the detected position is located in an adjacent area that is predetermined for the outside of the control input area, that is, the edge area of the control input, it may also be obtained. The position information is used as an enlarged information of the control input area, and the control input area is enlarged and displayed to a preset multiple, wherein the predetermined distance may be a distance set according to actual needs. After zooming in, the magnified display gives the user a very intuitive feeling, and the button has been enlarged and displayed before the touch. When the user sees that the enlarged unit is not the button that the user expects to input, the input medium can be moved horizontally to reach When the corresponding unit is above, the corresponding sensing unit performs the same action. Step S808, the user inputs the touched button of the medium, and the touch screen finally detects the user input to obtain corresponding input information, and the terminal can perform a corresponding action according to the input information. FIG. 9 is a schematic diagram showing the input result of the method shown in FIG. 8 according to an embodiment of the present invention. As shown in FIG. 9, after the enlarged button, the user does not substantially generate a selection error caused by the touch deviation. The virtual keyboard with the proximity detecting unit provided by the embodiment can enlarge the control input area on the touch screen when the user's input medium approaches the touch screen, and the user can further perform touch input, thereby effectively improving the accuracy and effectiveness of the input button. Sexuality effectively solves the key touch error of the virtual keyboard when input, and the secondary selection or rollback after the error is generated, thereby improving the user experience.
