The character input method provided by the application adopts a mode of determining the characters by relative positions, so that the electronic equipment does not need to display a virtual keyboard any more in the character input process, and the display area of the touch screen is avoided being occupied. The following describes the character input method provided by the present application in detail by using specific embodiments.
One embodiment
Referring to fig. 1, a flow chart of a character input method provided by the present application is shown, where the character input method is applied to an electronic device including a touch screen, and may include the following steps:
step 101: the method comprises the steps of obtaining a first position of a first touch point on the touch screen, and determining a first input character corresponding to the first position.
Step 102: a second location of a second touch point on the touch screen is obtained.
When an object touches a touch screen of the electronic device, for example, a finger of a user touches the touch screen, a touch point is formed on the touch screen. A camera in the electronic equipment collects images formed on the touch screen, and then an image recognition chip of the equipment in the electronic equipment analyzes the images collected by the camera to recognize touch points on the touch screen, so that the positions of the touch points on the touch screen are obtained. The second touch point is a touch point formed on the touch screen at the current moment, and the first touch point is a touch point formed on the touch screen at the previous moment.
In this embodiment, the position of each touch point may be a position of the touch point relative to a center point of the touch screen or a position of a certain corner of the touch screen. Of course, the position of the touch point may also be the position of the touch point relative to the positioning point. The positioning point is a point formed by a certain key in the virtual keyboard on the touch screen, the position of the touch point relative to the positioning point can be directly above the positioning point, directly below the positioning point and 30 degrees to the left of the positioning point, and the specific position can be set according to an application scene.
The locating point is displayed on the touch screen when the electronic equipment starts character input operation, the locating point can be a point formed by an H key in an existing virtual keyboard on the touch screen or a point formed by an Enter key on the touch screen, the position of the locating point in the touch screen is preset in the electronic equipment, and the computing method of the position of the locating point in the touch screen can adopt a computing method of the absolute position of the locating point in the touch screen after the existing virtual keyboard is started.

In this embodiment, the second input character determination process may be: and selecting a character associated with the first input character from a preset vocabulary table according to the position relation and the first input character, and determining the character as a second input character, wherein the preset vocabulary table comprises words existing in a standard dictionary, or the preset vocabulary table comprises words existing in the standard dictionary and recorded words input by the user before. The specific operation process is illustrated.
For example, the positioning point is a point formed by the H button on the touch screen, the first input character is a, the position relationship is directly above the positioning point, and the characters directly above the positioning point can be y and u according to the position relationship. The resulting character is combined with the first input character to yield a first string au and a first string ay. Inputting the first character string into a preset vocabulary table, checking whether a vocabulary comprising the first character string exists, and if so, determining the obtained character as the second input character.
By applying the technical scheme, the electronic equipment can firstly obtain the first position of the first touch point on the touch screen and determine the first input character corresponding to the first position. After the second position of the second touch point is obtained and the position relationship between the second touch point and one point in the touch screen is obtained, the second input character corresponding to the second position can be determined according to the position relationship and the first input character. That is to say, the electronic device can determine the characters according to the relative positions between the points, so that when the electronic device performs the character input operation, the virtual keyboard is not displayed on the touch screen, the display area of the touch screen is prevented from being occupied, and the actual content can be displayed in the whole display area of the touch screen.
Further, the existing virtual keyboard matches characters according to the absolute positions of the keys, that is, when a certain key is touched, the virtual keyboard can only match one character according to the absolute position of the key. When a certain key is touched, the adjacent keys are touched by mistake, namely, when the touch point is wrong, the virtual keyboard can only be matched with a wrong character according to the absolute position.
In this embodiment, the electronic device may determine the second input character according to the position relationship and the first input character, and therefore, when the adjacent key is touched by mistake, the character corresponding to the position of the touch point may include a wrong character and a correct character, so that the electronic device may obtain the correct character by using the character input method provided by the present application, and implement automatic error correction, and particularly when characters corresponding to positions where a plurality of touch points are located are continuously matched, the automatic error correction effect is better.
