TABLE 1
To explain by taking fig. 4 as a specific example, a character 1012 to be selected and a focusing frame 1013 are displayed on a display interface of the touch screen, where the character to be selected is suspended in a specific shape and appears on the display interface, for example, in an arc shape in fig. 4; further identifying the selection operation of the user 1052 on the character to be selected, so that the character to be selected falls into the focusing frame to become a character to be input; and finally, recognizing the confirmation operation of the user and inputting the character to be input corresponding to the focusing frame at the moment, for example, recognizing the confirmation input of the user on the touch operation of the confirmation key 1031 on the display interface.
In the above embodiment, the page of the character to be selected is presented on the display interface in a suspended state, the shape of the character to be selected is a rectangular plane, a square plane, an arc surface, a sphere, a cuboid or a cube, and when the character to be selected is a plane or an arc surface, all the characters are uniformly or non-uniformly distributed and displayed on the surface of the plane or the arc surface; when spherical, a uniform or non-uniform distribution of all characters is displayed on the spherical surface; in the case of a cube or a rectangular parallelepiped, corresponding characters can be displayed on each surface of the cube or the rectangular parallelepiped according to a predetermined setting.
In the above embodiment, the selection operation of the user on the character to be selected is identified so that the character to be selected falls in the focus frame and becomes a character to be input, which may specifically use the following modes: 1. identifying the movement operation of the user on the character to be selected, wherein the selection operation can drag the page of the character to be selected to enable the character to be selected to fall into a focusing frame; 2. recognizing the movement operation of a user on the focusing frame, fixing a character page to be selected at the moment, dragging the focusing frame, and setting the corresponding character in the focusing frame as a character to be input at the moment; 3. identifying the moving operation of the user on the character to be selected and the moving operation on the focusing frame at the same time, wherein the page of the character to be selected can be moved by one hand, and the focusing frame can be moved by the other hand, so that the character to be selected falls into the focusing frame; 4. identifying touch operation of a user on the focusing frame, and simultaneously identifying the inclination direction of the terminal equipment to move the character to be selected, wherein the mode identifies the gyroscope function of the mobile terminal, and identifies the rotation angle to further control the movement of the character page to be selected; 5. and identifying the inclination direction of the mobile terminal to move the focusing frame, wherein the mode does not need to be selected through touch screen contact, but adopts a gyroscope function of identifying the mobile terminal, identifies the rotation angle of the mobile terminal to further control the movement of the focusing frame, and finally fixes the focusing frame on the character to be input.
The invention provides a preferred embodiment, on the basis of the above embodiment, when the character to be selected falls into the focusing frame, the character to be selected is displayed in the focusing frame in an enlarged manner, which is very suitable for the case that the display screen is small or the user wants the character to be larger. Of course, the amplification may be at other locations.
In a preferred embodiment of the present invention, the confirming operation of the user is performed, the input of the character to be input is performed by multi-touch of the user, and a plurality of identical characters to be input are input, where the number of the characters to be input is the same as the number of the touch points of the user. Specifically, the multi-touch here refers to a scene of simultaneous multi-touch, and the multi-touch is recognized on the confirmation key, and at this time, a plurality of identical characters to be input are input, for example, a character to be input corresponding to the current focus frame is "x", and at this time, it is recognized that the user touches the confirmation key with 3 fingers, and at this time, it is confirmed that "xxx" is continuously input. For the confirmation operation of the recognition user, the confirmation operation can be determined by releasing the touch screen after the recognition user selects the character without specially setting a confirmation key.
The present invention also provides a preferred embodiment, as shown in fig. 5, there are two focusing frames, namely a first focusing frame 1013 and a second focusing frame 1014; the identification of the selection operation of the user on the character to be selected comprises the following steps: identifying simultaneous sliding operation of at least two touch points of a user so as to enable the characters to be selected to fall into at least two corresponding focusing frames respectively; the recognizing the confirmation operation of the user and inputting the character to be input includes: and recognizing that the character to be input corresponding to the focus frame which is released and controlled firstly completes the input. Specifically, the sliding operations of the first focus frame 1013 and the second focus frame 1014 by the user are respectively recognized so that the characters to be selected fall into two focus frames, respectively, and the user can simultaneously perform the input of two characters. And inputting the character corresponding to the focus frame with the touch released firstly. For example, it is recognized that the user moves the first focus frame to the character "9" and the second focus frame to the character "b", and at this time, it is recognized that the touch corresponding to the second focus frame is released first, and then the character "b" to be selected is input first, and then the character "9" to be selected is input. In this state, of course, the two focus frames may be fixed, and the page of the character to be selected may be further subjected to a sliding operation, but in this case, since the positions of the two focus frames are fixed, the character to be input may also present a fixed input.
The invention also provides a preferred embodiment, the focusing frame comprises a holding state, the holding state can be entered by specially setting a holding key, and can also be entered by double-clicking or triple-clicking or long-pressing the touch screen. The holding key has a part or all of a function that can be set as desired when designing a specific product.
When the focusing frame is in a holding state, sliding the focusing frame, and taking the sequence of the characters to be selected which are slid by the focusing frame as characters to be input; for example, in fig. 4, when the focus frame is in the hold state and the recognition focus frame continuously slides over the character "abcdml", the character "abcdml" to be selected may be continuously input without performing the confirmation operation a plurality of times at this time.
When the focusing frame is in a holding state, the character to be input is kept fixed, and the focusing frame is slid left and right or up and down to realize repeated input or deletion of the character to be input; for example, the focus frame is currently located at the character "b", and a plurality of characters b can be continuously input by sliding left and right to input the character "bbbbbb", and when the focus frame is slid up and down, a plurality of input characters are continuously deleted.
When the focusing frame is in a holding state, the characters to be input are kept fixed in the left-right direction, the up-down direction is not fixed, when the focusing frame slides in the up-down direction, the characters to be selected, which slide through the focusing frame, are sequentially used as characters to be input, and when the focusing frame slides in the left-right direction, repeated input or deletion of the characters to be input is realized; for example, when an X character falls into a focus frame, a user operation is recognized, the focus frame enters a hold state, at this time, the left and right direction of the character to be input is kept fixed, which means that dragging the focus frame in the left and right direction cannot change the character in the focus frame, only can input the X character and delete the input character, and as for which direction is input, which direction is deleted can be set by itself, and dragging the focus frame up and down can realize sequential input of the characters falling into the focus frame.
When the focusing frame is in a holding state, the characters to be input are kept fixed in the vertical direction, the left and right directions are not fixed, when the focusing frame slides in the left and right directions, the characters to be selected, which slide through the focusing frame, are sequentially used as the characters to be input, and when the focusing frame slides in the vertical direction, repeated input or deletion of the characters to be input is realized; this embodiment is different from the previous embodiment only in the fixed direction, and is not described again.
When the focusing frame is in a holding state, the focusing frame is moved to the position of any character to be selected through the operation on any character to be selected. For example, when the X character falls into the focusing frame, the user operation is recognized, the focusing frame enters the holding state, and in the holding state, the operation of the Y character by the user is recognized, and if the operation is clicked, the focusing frame directly moves to the Y character.
In one embodiment, when the focus frame is in the hold state, the characters to be selected are blurred except the character falling into the focus frame. Note that, in general, the blurring is slight to indicate that the hold state is entered and to highlight the character falling into the focus frame.
In one embodiment, when the focusing frame is in a holding state, the focusing frame displays operation instructions in at least two directions, and operation prompt in each direction is carried out according to the function setting of the focusing frame in the holding state. For example, when the device enters the hold state, the focus frame displays a cross-shaped indication of up, down, left, and right, the left and right directions prompt sliding input, the up direction prompt input of a currently-to-be-input character, and the down direction prompt deletion of an input character.
According to another aspect of the embodiments of the present invention, there is also provided a character input device, which can implement efficient character input. The embodiment of the invention is realized in such a way that a character input method comprises the following steps:
the display device is used for displaying the characters to be selected and the focusing frame on the display interface;
the recognition device is used for recognizing the selection operation of the user on the character to be selected, and the selection operation enables the character to be selected to fall into the focusing frame to become the character to be input;
and the confirmation device is used for identifying the confirmation operation of the user and inputting the character to be input.
The device corresponds to the above-mentioned embodiment of the input method, and is not described herein again.
