Fig. 1 is a flowchart of a display control method according to an embodiment of the present invention; the method may include the following steps S10-S12.
S10, when a virtual keyboard display request is received, capturing a sliding track of a terminal screen;
in a specific embodiment, the virtual keyboard display request may be a single-hand input mode starting instruction, and when the user needs to perform single-hand input, the single-hand input mode is started, that is, the virtual keyboard display request is sent. Specifically, the virtual keyboard display request may correspond to an operation of a user, and the terminal identifies the user operation and starts a one-handed input function, that is, captures a sliding trajectory of the terminal screen, when the operation is determined to be the virtual keyboard display request. Specifically, optionally, in the local configuration of the terminal, a certain specific operation is preset to be associated with the virtual keyboard display request, when the user executes the operation, the terminal identifies the user operation, determines that the operation corresponds to the virtual keyboard display request by querying the local configuration, and prompts the user to perform a stroke on the touch screen of the terminal on the screen to determine the virtual keyboard display area. After the user starts to stroke, the terminal captures the sliding track and displays the sliding track on the screen in real time, as shown in fig. 4.
After the user starts to stroke the fingers, the terminal collects and stores data of the stroke track, namely corresponding screen coordinate data, at regular intervals. The time interval of data acquisition is subject to the condition that the acquired data can ensure that the sliding track is identified and recovered with certain precision.
Judging whether the sliding track of the terminal screen is finished, specifically, the method for judging the end of the screen sliding comprises the following steps: and in a continuous time period, the coordinate data acquired by the terminal is empty, namely in the time period, the user does not perform the sliding operation on the touch screen by the finger, and the sliding track is determined to be finished. And after the terminal judges that the sliding is finished, feeding back confirmation information to prompt a user to confirm the sliding track. And if the user confirms, executing the step 101, otherwise, returning, and continuing to acquire the coordinate data.
S11, determining a sliding area constructed by the sliding track and the boundary of the terminal screen;
in a specific embodiment, a sliding area constructed by a sliding track of the terminal screen and a boundary of the terminal screen is determined, and optionally, the boundary of the terminal screen may be a certain side or two sides of the left side, the right side and the bottom side of the touch screen. As shown in fig. 4, the left and bottom edges of the touch screen are used as the boundaries of the terminal screen. The boundary between the sliding track and the terminal screen may constitute a sliding area, which may facilitate the one-handed operation of the user, as shown in fig. 4. It should be noted that, if the sliding track does not touch the boundary of the terminal screen, the sliding track may touch the boundary after analyzing and processing the coordinate data. The method can be realized by using methods such as data fitting, data prediction and the like in a mathematical modeling method.
And S12, displaying each key unit of the virtual keyboard in the sliding area.
In a specific embodiment, each key unit of the virtual keyboard is displayed in the sliding area, and optionally, the shape of the key unit may be a regular hexagon.

When the sliding area is large, the number of the key units is large correspondingly; when the sliding area is smaller, the number of the key units is less, so as to realize the maximum area coverage of different sliding areas. As shown in fig. 5, since the sliding area of the left screen is large, the number of key units is large, and the sliding area of the right screen is small, the number of key units is small.
Optionally, if the sliding area is small and one interface is not enough to display all the key units, as shown in fig. 6, the screen may be slid to the left, and the second interface is entered to display the rest key units; similarly, when the current screen is displayed as the second interface, as shown in fig. 7, the screen may be slid to the right, and the first interface is entered, and the two interfaces in the sliding area may be switched. It should be noted that the sliding switching described in this embodiment is only an optional implementation manner, and may also be another switching manner.

In the local configuration of the mobile terminal, a key size adjustment key is preset, and when a user presses the key, a key size adjustment instruction is executed. Here, after the user completes the adjustment of the number and size of the keys, the screen feeds back the confirmation information. If the user confirms the adjustment information, step 109 is executed, otherwise, the number and size of the keys are readjusted. Here, in the mobile terminal local configuration, a key adjustment confirmation instruction is preset. It can be set as follows: and any area outside the keyboard display area is clicked or double-clicked, namely, the key adjustment is confirmed.
Step 109: and displaying the keyboard.
And after the user confirms the key adjustment, the touch screen displays the adjusted virtual keyboard.
Step 110: the one-handed input mode is turned off.
Here, in the local configuration of the mobile terminal, it is preset that a certain specific operation is associated with the above-mentioned one-handed input function closing instruction, when the user performs the operation, the mobile terminal recognizes the user operation, determines that the operation corresponds to the one-handed input function closing instruction by querying the local configuration, and closes the one-handed input function.
