And record and transmit the relevant data of each contact. Data related to a touch operation may include but not limited to the following actions:

●The starting point where the user presses the touch point

●The end position where the user releases the touch point

●Track of user’s mobile touch points

●The dwell time of the user to keep touch points

According to the current keyboard layout, the layout mapping module 402 maps the contact operations reaching the response threshold to the layout set corresponding to this input, and outputs it to the layout module 404 .

Among them, the layout mapping module 402 firstly defines and stores various layout parameters of different keyboards, such as the discrete layout 102, 103 keyboard area (each occupying 30% width), the reduced center layout (50% width) and so on. Secondly, the contact operation reaching the response threshold is mapped to the layout set corresponding to this input. Referring to Figure 7 again, it describes a data structure describing the keyboard layout in memory, which may include (but not limited to) the following fields:

●The position and size of the layout on the keyboard area

●The location and size of the layout on the screen area

●The characters displayed on the key and their corresponding position areas

●A set of layouts corresponding to the input of different actions of the user

The layout module 404 receives and reads the layout list mapped to the current contact movement, arranges them in sequence, and responds in real time to the layout state after the contact action ends.

The output imaging module 405 is responsible for outputting the keyboard layout to the device in a certain way and presenting it to the user. At the same time, when the user operation changes, the output imaging module 405 can re-render the updated layout for dynamic presentation.

The setting module 403 stores user and system settings, such as layout switch animation mode, layout switch pending, proportional zoom layout, custom keys, etc., for use by the layout mapping module 402 and the layout module 404 .

Wherein, the setting module 403 is optional, and the setting module 403 may contain various setting information related to system operation, including user preference, system working mode, and the like. For example, the user may select a layout animation display mode. The layout can be presented with animation effects such as fading in and flying in; another example, the user can choose to lock the height of the layout, and only swipe to change the width of the layout.

In the present invention, based on the above-mentioned system, the method for setting and controlling discrete keyboard layout switching includes the following steps:

(1) The system waits for the user's input operation;

(2) The input detection and control module in the system judges whether the user's input operation is correct, including the following steps:

(a) The input detection and control module judges whether the user's input operation reaches the system response threshold;

(b) If yes, then return the correct result of the user's input operation;

(c) If not, return the result that the user's input operation is incorrect;

(3) If not, the layout mapping module feeds back an empty set, and returns to the above step (1);

(4) If yes, the layout mapping module generates the layout set corresponding to the user's input operation this time, specifically:

The layout mapping module dynamically generates a corresponding layout set according to the relevant data of the user's input operation, and the relevant data includes:

(a) The starting position information of the user pressing the touch point;

(b) The end position information of the user releasing the touch point;

(c) Track information of the user's mobile touch points;

(d) The user maintains the residence time information of the touch point;

The layout collection in the method for implementing the discrete keyboard layout switching setting control includes the following field information:

(a) the position and size of the layout on the keyboard area;

(b) the location and size of the layout on the screen area;

(c) The characters displayed on the keys and their corresponding position areas;

(d) The layout set corresponding to the input of different operations of the user;

(5) The layout module generates a layout list according to the layout set;

(6) The output imaging module performs real-time sorting, rendering and imaging, and outputs the updated keyboard layout.

See also shown in Fig. 5 again, it is the optimal implementation mode of the present invention, wherein has described the main flow process 500 of keyboard software main program when finishing user switching keyboard layout, comprises the following steps:

(1) Waiting for user input operation (step 501).

(2) judging whether the operation is correct (step 502);

In the step 502, the input detection and control module 401 judges whether the current input operation is correct. The layout mapping module 402 is triggered when a set response threshold is reached or any other pre-specified operation is reached.

(3) After being judged as negative by the detector and the controller, the layout mapping module feeds back an empty set, and returns to 501 (step 503 ).

(4) After being judged as yes by the detector and the controller, a layout set corresponding to this touch is generated in the layout mapping module (step 504);

In this step 504, the layout mapping module 402 can map this current touch point movement into a corresponding layout set according to the current keyboard layout. For example, when the user slides two fingers outward in the keyboard layout shown in Figure 1B in the reverse direction, a layout set is generated after reaching the touch point response threshold, and when the user stops touching at any position, after the layout module receives relevant data (such as parameters , coordinates, etc.), dynamically generate the current layout.

(5) Generate a layout list in the layout module and perform real-time sorting and rendering (step 505).

(6) output the updated keyboard layout (step 506);

In this step 506, the output module 406 can re-render the updated layout for dynamic presentation. In some embodiments, layout dynamic presentation modes (including but not limited to fade-in, fly-in, float-in, etc.), custom keys, etc. can be defined through the setting module 403 .
