Description
Technical Field
The present application relates generally to the field of text input, and more particularly, to an input method, an input apparatus, an input system, and an electronic device.
Background
The interactive mode of indirect input often occurs in the case where the input plane and the display plane are separated. A typical scenario is that a user holds a mobile phone, a remote controller or a handle, and interacts with a smart television, a large screen, a Virtual Reality (VR) head-mounted display, Augmented Reality (AR) smart glasses, and the like. In these scenarios, the display screen and the input device are on two separate planes that are decoupled.
There are many search and chat using requirements in these scenarios, and the text input in these scenarios still has many defects.
For example, one scheme is to display a 26-key keyboard on a screen, move a cursor in units of keys using direction keys or a jog dial (up, down, left, and right) of a remote controller or a handle, and input one character by pressing a confirmation key. The scheme has the defects that the input is carried out by taking letters as units, the input efficiency is low, and the operation times are more when the keys are moved.
Another solution is to display a 26-key keyboard on the screen, move the cursor by shaking (gyro), and press the enter key to enter a character. The scheme has the defects that the input is carried out by taking letters as units, the input efficiency is low, the accuracy rate of operating the cursor in a shaking mode is low, the efficiency is low, and the learning cost is high.
In another scheme, a 26-key keyboard is displayed on a screen, a cursor is moved through a touch screen, and a character is input by pressing a confirmation key. The disadvantage of this scheme is that the input is performed in units of letters, the input efficiency is low, and two operations of moving and pause confirmation are required between the input of each character, and the input efficiency is low.
In addition, schemes for speech input have also been developed. However, this scheme has a disadvantage that the recognition accuracy of speech recognition is limited (support for accents, noisy environments, confusable words is not good), and further, it is not suitable for use in some cases (silent environments, private information). Also, the voice input scheme requires a microphone and requires more computing resources than other schemes.
It is therefore desirable to provide an improved input scheme for the case where the input plane and the display plane are decoupled, separate planes.

Detailed Description
Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and that the present application is not limited by the example embodiments described herein.
Exemplary method
Fig. 1 is a schematic flow diagram of an input method according to an embodiment of the application. As shown in fig. 1, an input method according to an embodiment of the present application is applied to a first device having a display unit, including: s101, receiving a first sliding track input by a user from a second device, wherein the first sliding track is generated by the user performing a first sliding touch operation on an input unit of the second device; s102, displaying the first sliding track and a soft keyboard for text input on the display unit while receiving the first sliding track; s103, matching the first sliding track with at least one candidate word in a word bank according to a preset matching algorithm; and S104, displaying the at least one candidate word on the display unit; wherein the first sliding track is displayed such that the starting point of the first sliding track is at the center of the soft keyboard.
In the input method according to the embodiment of the application, the input is performed in units of words, but not in units of letters, so that the input efficiency is improved, and the fault tolerance rate is high.
Moreover, by adopting the input method according to the embodiment of the application, when a user inputs a text, eyes can always watch the display unit of the first device without watching the input unit of the second device, so that the visual angle does not need to be switched back and forth between the input device and the display device during the input, the input efficiency of the user is improved, and the user experience is improved.
Here, the first sliding touch operation performed by the user on the input unit of the second device may be a sliding touch operation performed by a finger of the user, or may be a sliding touch operation performed by another input device for touch operation, such as a touch pen.
In the input method according to the embodiment of the present application, the first device displays a first slide trajectory input by a user on the display unit in real time while receiving the first slide trajectory from the second device, so that the user can recognize a trajectory of a slide input on the input unit of the second device, for example, a touch screen, on the display screen. For example, in the input method according to the embodiment of the present application, a 26-key keyboard is displayed on a screen, and a cursor is moved using a touch screen, and the cursor is moved correspondingly on each key of the 26-key keyboard. In this way, a cursor on a virtual keyboard displayed on the display screen can continuously provide visual feedback, enabling a user to input more accurately and quickly.
The user draws a trajectory by a gesture on, for example, a touch screen by a sliding touch operation on the input unit of the second device, passing through each letter of the input word in turn. Then, the algorithm provides a plurality of candidate words according to the comparison of the sliding track and the standard tracks of all the words in the word bank. Here, those skilled in the art will appreciate that various matching algorithms may be employed to determine one or more candidate words based on the sliding trajectory of the user, and the present application is not intended to be limited to any particular method.
As described above, since the matching algorithm may determine a plurality of candidate words based on the sliding trajectory of the user, the user needs to select a desired one of the plurality of candidate words.
The plurality of candidate words may be selected in a list, but in the input method according to the embodiment of the present application, a vote interface is displayed on the display screen, and the plurality of candidate words are displayed in a tiled layout on the vote interface, thereby facilitating a user to select one of the plurality of candidate words through a specific gesture on the input unit of the second device, for example, a sliding touch operation in a specific direction.
Fig. 2 is a schematic diagram of a candidate word selection operation of an input method according to an embodiment of the present application. As shown in fig. 2, a ring menu is used for word selection, and under the word selection menu, the user can type a word by moving the cursor in four directions and releasing, and then enter the track input stage of the next word. Of course, it will be understood by those skilled in the art that although four words are shown in a ring in fig. 2, more words may be shown in a similar layout and candidate words may be selected by a sliding operation in the corresponding direction.
That is to say, in the input method, the at least one candidate word includes a plurality of candidate words, and displaying the candidate words on the display unit specifically includes: displaying a word selection interface for selecting the plurality of candidate words on the display unit, wherein the interface comprises a plurality of positions, and each of the plurality of positions respectively displays a corresponding one of the plurality of candidate words.
Also, in the above input method, after displaying the candidate word on the display unit, further comprising: receiving a second sliding track input by a user from a second device, wherein the second sliding track is generated through a second sliding touch operation of the user; determining a selection position pointed by the second sliding track; and selecting one of the plurality of candidate words displayed at the corresponding position based on the selection position.
Also, a trajectory of the second sliding touch operation by the user may be displayed on the display screen, thereby continuously providing visual feedback to the user so that the user can input more accurately and quickly.
Therefore, in the above input method, further comprising: displaying a second sliding track input by a user on the display unit while receiving the second sliding track from a second device, wherein the second sliding track is displayed such that a starting point of the second sliding track is in the center of the word selection interface.
Here, since the user always looks at the display unit of the first device without looking at the input unit of the second device when performing input in the input method according to the embodiment of the present application, the user cannot actually know the start of input position on the input unit of the second device with certainty. For example, when a user holds a smartphone having a touch screen for input, although the user can see the trajectory of the slide input on the display screen, the position where the slide input starts, that is, the position where the finger starts to contact the touch screen of the smartphone, cannot be known with certainty at the start of the slide input.
Therefore, if the user needs to look at the touch position of the finger on the smartphone at this time, the input efficiency of the user is obviously reduced, and great inconvenience is brought to the user.
Fig. 3 is a schematic diagram illustrating an exemplary keyboard layout on a smartphone. The layout of a keyboard on a touch screen of a smartphone suitable for single-handed thumb operation is shown in fig. 3. However, fig. 3 illustrates that, in practice, in the input method according to the embodiment of the present application, the user does not need any display on the touch screen when actually using the input method, and the user's eyesight and attention will be focused on the display screen completely without switching between the display screen and the touch screen in the hand (e.g., VR immersive experience, etc.).
Moreover, it should be noted that, since the operation of the user on the touch screen of the smartphone is displayed on the display screen, the keyboard layout of the touch screen and the aspect ratio on the display screen are preferably the same, and the operation of the user on the touch screen is also proportionally mapped to the cursor on the display screen.
In addition, in order to solve the above problem, it is arranged to always display the start point of the first slide locus on the display unit at the center of the keyboard, for example, at the position of the letter G on the keyboard. That is, the touch position of the user's finger, i.e., the cursor position, is displayed on the display screen at the center of the keyboard, e.g., at the position of the letter G, no matter where the user's finger is actually on the touch screen. Thus, the trajectory of the on-screen gesture keyboard starts from the midpoint of the keyboard, no matter from which position on the touch screen the user starts to slide the trajectory. Therefore, the problem that the first drop point of the user is not accurately clicked under the blind input condition is completely solved because the track starting point is fixed at the center of the keyboard. Therefore, the input method of the embodiment of the application has the advantages of low learning cost, small psychological burden, increased input efficiency and accuracy and improved user experience.
In addition, the track starting point is fixed at the center of the keyboard and is combined with the annular menu for word selection as shown in fig. 2, so that the switching cost of the user in two modes of track input and word selection is extremely low.
Therefore, in the input method according to the embodiment of the present application, the second slide trajectory is similar to the first slide trajectory, and the start point thereof is also displayed at the center position of the ring menu. That is, the second sliding track is displayed such that the starting point of the second sliding track is at the center of the vote interface.
Of course, in this case, when the user selects a word through the sliding trajectories, each sliding trajectory starts from substantially the center of the keyboard, and thus the sliding trajectory of the user passes more letters than the letters of the word to be input substantially. For example, if the word the user wants to enter is "the," its corresponding standard trajectory should pass through "gthe" for each letter in turn.
After the user inputs the first sliding track for inputting letters, the display unit displays a word selection interface, and at the moment, a first cursor for marking the first sliding track is automatically reset to the center of the word selection interface, so that the user can conveniently select words next. Also, after the user inputs the second sliding track for word selection, the display unit displays the soft keyboard for letter input again, and at this time, the second cursor for identifying the second sliding track should also be automatically reset to the center of the soft keyboard, for example, the cursor is automatically reset to "G" to facilitate the input of the next word.
Of course, it will be understood by those skilled in the art that the first cursor may also be reset to the center of the soft keyboard after the first sliding track, and likewise, the second cursor may also be reset to the center of the vote interface after the second sliding track.
That is, regardless of whether the first cursor that identifies the first slide trajectory or the second cursor that identifies the second slide trajectory, after the input of the first slide trajectory and the second slide trajectory is ended, it is automatically reset to the center of the soft keyboard interface for text input or the vote interface for vote, thereby facilitating the next input.
Therefore, in the above input method, the soft keyboard is displayed with a first cursor that identifies the first sliding trajectory; and automatically resetting the first cursor to the center of the word selection interface or the soft keyboard after the first sliding track is displayed.
And, in the above input method, after selecting one candidate word of the plurality of candidate words displayed at the corresponding position based on the selection position, further comprising: the word selection interface is displayed as a second cursor with the second sliding track marked; and the second cursor automatically resets to the center of the soft keyboard or the word selection interface after the second sliding track is displayed.
As described above, in order to adapt to the size of a touch screen of, for example, a smartphone, in the input method according to the embodiment of the present application, it is preferable that the keyboard shape is closer to a square (the aspect ratio of each key is close to 1:3), and is more suitable for one-handed thumb operation and higher in accuracy and comfort than a general physical keyboard and a soft keyboard (the aspect ratio of each key is close to 1: 1).
Therefore, in the above input method, the soft keyboard is a 26-key keyboard with a key aspect ratio of 1: 3.
In addition, in the input process, the user can also realize other functions through common single-click or double-click input, such as switching candidate words, quitting the word selection interface and the like. Furthermore, if the user wants to delete a word that has been entered, it can also be done by a specific operation, such as a double-click operation or a quick left-stroke operation.
That is, in the above input method, further comprising: receiving a single-click operation of a user from the second device; and in response to the single-click operation, respectively displaying other candidate words in the plurality of candidate words at each of a plurality of positions on the display unit.
Further, in the input method, the method further includes: receiving a double-click operation of a user from the second device; and responding to the double-click operation, and ending the display of the word selection interface.
Further, in the above input method, before receiving the first sliding trajectory input by the user from the second device, the method further includes: receiving a double-click operation or a quick left-stroke operation of a user from the second device; and deleting the last input word in response to the double-click operation or the quick left-stroke operation.
In summary, the input method according to the embodiment of the present application supports text input based on indirect touch input, and a user can input words by moving a cursor on a touch screen and sliding out a track of the words while holding a device (such as a mobile phone, a handle, a remote controller, etc.) with the touch screen, thereby having high input efficiency and fault tolerance.

FIG. 4 is a schematic block diagram of an input device according to an embodiment of the present application.
