Along with the optimization of a visual interface in a computer operating system, the operation of simplifying a flow through a mouse is more and more, so that when a user wants to efficiently perform an interactive operation with the computer, the user often needs to use the mouse and the keyboard simultaneously.
However, there are many times when there is no way to use both devices at the same time due to differences in usage scenarios, computer devices, etc. in everyday use. If business trip office is generally carried out by carrying a notebook computer, because the keyboard is large in size and needs to occupy more space, the notebook computer is usually carried with a mouse to carry out office by matching with the keyboard of the notebook computer, the keyboard of the notebook computer is generally a short-stroke keyboard based on the carrying requirement, and part of users are difficult to adapt to the short-stroke keyboard based on factors such as physique and habit. There are cases where the narrow office space is inconvenient for simultaneous use of a keyboard and a mouse, etc., and when only a small-sized desk board with a standard keyboard can be put down, as shown in fig. 1, the full-sized keyboard occupies the desktop space, and the typing input area is deviated from the center line of the desk board, which is generally replaced by a small-sized keyboard such as 87 keys or 68 keys to satisfy the active space of the mouse, or a scheme such as a notebook computer keyboard and a touch pad is adopted. However, the keyboard is replaced by a conventional mouse, so that the keyboard is far away from the conventional mouse, and the displacement of the typing input area can affect the placement of the arms during text input, and meanwhile, good support cannot be provided, so that the keyboard is not in accordance with ergonomics and is easy to affect the posture over time. The touch pad scheme is inconvenient in operation compared with a traditional mouse, and is easy to operate by mistake.
For this reason, if a keyboard apparatus capable of performing a mouse or other input structure simulation using the idle key positions at the time of the conventional input can be developed, the above-mentioned problems can be well solved. Although the existing keyboard manufacturers also set various combination keys or function keys on the keyboard, the conventional keyboard key signal input is usually a digital signal such as 0 or 1, and by this signal, it is difficult to simulate the operation experience similar to the actual operation of the mouse.

step S1, switching from a normal input state to an analog input state through a function trigger key;
s2, after entering an analog input state, replacing standard key values of a plurality of key units at preset positions with analog key values; when the key unit at the preset position is pressed, the sensor outputs an electric signal to the processing module, the electric signal is in an increasing trend, and the processing module generates the analog key value with a corresponding value to computer equipment according to the increasing trend of the electric signal; when the output electric signal of the sensor is in a decreasing trend, the processing module stops outputting the analog key value;
and step S3, executing the step S2 until the user exits the analog input state through the function trigger key.
As shown in fig. 2, when the simulated object of the device simulation signal is that the mouse cursor moves leftwards in step S2, the user presses the key shaft body at t0, t2 and t4 respectively, and the processing module responds and outputs the mouse cursor movement signal to the computer device, so that the cursor moves at a corresponding speed. And the user releases the key shaft body at t1, t3 and t5, the corresponding processing module stops outputting the mouse cursor movement signal, and the processing module keeps static in the leftward movement direction when the trend is reduced.
In step S1, the function triggering key is the key unit set on the keyboard structure for presetting a switching function or inputting conventional characters. In this embodiment, the key unit with the preset switching function is an independent "Fn" key, and the processing module outputs the analog key value to the computer device when the plurality of key units preset as the mouse and the knob are triggered by pressing the "Fn" key; the key unit for inputting the conventional characters is used for enabling the key unit to output a switching signal to the processing module through a function switching method, the key unit for inputting the conventional characters is a Space key, and the processing module executes a state switching instruction to lock an analog input state after receiving the switching signal, namely, the effect of achieving the analog input state through cooperation of the Space key and the Fn key through the function switching method. The user can utilize the keyboard device to simulate the mouse area to complete cursor movement through the Fn key in a short time, the effect of keeping the simulation input state for a long time can be achieved through the function switching method, and the user releases the keeping of the simulation input state through executing the function switching method again. The state switching instruction is used for switching the output key value or executing the input state. Therefore, the quick use and long-term use of the simulation equipment are provided for the user, and the switching between the simulation input state and the conventional input state is convenient and quick.
In this embodiment, when the "Fn" key is triggered by the function switching method, the user directly enters an analog input state and locks the analog input state until the user triggers the "Fn" key again by the function switching method. The function switching method is directly executed on the Fn key with the preset switching function, so that a more convenient operation is provided for the user to switch the state for a long time.

The function switching method can be applied to executing state switching or outputting a second key value, for example, the original key output value is 1, and the function switching method is used for realizing the direct traditional keyboard which can be output only by pressing shift simultaneously-! "value, and thus enrich the functionality of the keyboard device. In addition, the minimum trigger distance between the standard key value and the replacement key value is independently set, so that the two trigger results are ensured not to conflict.

In the curve b, the processing module executes the output of the standard key value because the passing time is smaller than the preset 0.2 seconds in the interval of '5 < s < 15'.

When the two analog signals are cooperated, the processing module obtains analog signals output by the sensors corresponding to the two key units, compares the two analog signals in numerical value, takes the analog signal with large numerical value as the subtracted number to make difference with the other analog, outputs the analog key value corresponding to the analog signal with large numerical value, and outputs the signal according to the ratio of the result of making difference to the maximum analog quantity as the coefficient of the output frequency of the analog key value.
The numerical value of the output frequency is preset in a memory of the keyboard device, and when the processing module executes signal output, the product result of the coefficient obtained by detection and calculation and the set output frequency is used as the repetition frequency of the final output analog key value.
