Method for controlling plural input device, computer host, computer system and computer capable of reading recording medium

The present invention relates to a method of controlling a plurality of input devices, a computer host capable of controlling a plurality of input devices, a computer system capable of controlling a plurality of input devices, and a computer readable recording medium capable of controlling the plurality of input devices.

In general, computers are designed for a single user and only one person can use it at a time. Therefore, in the common computer class teaching, only a single input device (such as a single mouse) is used, and the teacher gives the students the right to operate the computer by referring the student to the designated student to view the student. Learning effect. However, since only a single mouse is used, the mouse must be exchanged for use. The exchange of the mouse is usually carried out by: (1) the mouse does not move, the teacher designates the student to use it, and the student must leave the seat; or (2) the student Stay in the same place and pass the wireless mouse to the student who wants to specify the operating mouse. However, in the process of mouse transfer, whether it is any of the above methods, it will affect the rhythm of teaching and reduce the overall efficiency of teaching.

Then please refer to Figure 1. 1 is a schematic diagram of a prior art computer system. Since the current computer technology can support multiple mouse or keyboard, just connect multiple mouse or keyboard to the control box, connect the control box to the USB hub, use the USB interface wired input device or wireless input device (such as Bluetooth). The mouse can expand the number of input devices in series, and the USB hub transmits the signals of all input devices to the computer through the USB port. Under this structure, each student has a mouse. When it is the turn of the student to operate, the teacher switches the control box to the student. Only the student uses and controls the mouse or keyboard, while other students stop. Operate the mouse or keyboard.

However, this approach will spread the problem of mutual interference. While today's computer technology can support the connection of multiple input devices, the computer operating system only supports the operation of a single input device (such as a single mouse or a single keyboard). The input device takes a mouse as an example, and the control of the mouse is the sum of all the actions of all the mice connected to the host computer. For example, if a student's mouse moves down 10 points and the other moves up 5 points, the computer knows that the mouse's movement is the sum of the up and down, and finally the mouse moves down 5 points, thus completely Deviate from the user's expectations. In addition, when a student who does not specify the operation inadvertently touches the mouse, it will also interfere with the normal operation of the designated student's mouse, especially when the number of the mouse is increased, the more serious the interference situation will be.

In addition, in the prior art, the purpose of switching the input device is achieved by a hardware switching method. When an input device is turned off, the input device is disconnected from the host computer (that is, it is not electrically connected), and the computer host cannot connect and read any signal of the input device. To switch the input device from off to on, you will need to reconnect. However, each time the input device is connected, the host computer needs to perform complex detection and communication with the input device to re-establish the connection, so it takes some waiting time (usually at least several seconds). If it is in the teaching situation, using the hardware switch mode to switch to the input device of different students will waste a lot of waiting time, which is not conducive to the computer course.

Therefore, it is necessary to provide a method for controlling a plurality of input devices, a computer host capable of controlling a plurality of input devices, a computer system capable of controlling a plurality of input devices, and a computer readable recording medium capable of controlling a plurality of input devices to improve the prior art There are problems.

Please refer to Figure 2. 2 is a block diagram of a computer system of the controllable plurality of input devices of the present invention. The computer system 100 of the present invention includes input devices 90a, 90b, 90c, a computer host 1 and a selection device 80, wherein the input devices 90a, 90b, 90c and the selection device 80 are electrically connected to the computer host 1. In this embodiment, the input devices 90a, 90b, and 90c are electrically connected to the host computer 1, and the selection device 80 is electrically connected to the computer host 1. However, the connection manner of the computer system 100 of the present invention is not limited thereto.

Input devices 90a, 90b, 90c are capable of generating a plurality of standard format signals. Further, each of the input devices 90a, 90b, and 90c can generate a standard format signal, which is a standard format signal that can be correctly interpreted by the operating system 400 of the host computer 1. The standard format signal is a general input device. The signals originally generated by 90a, 90b, and 90c.

The input devices 90a, 90b, and 90c may be devices such as a mouse or a keyboard that can operate the computer host 1 according to the instructions of the user. For example, when the input device 90a, 90b, 90c is a mouse, the user can input the computer host 1 by moving the cursor, pressing the left and right buttons, scrolling the wheel, etc.; when the input devices 90a, 90b, 90c are keyboards, the user You can press any button on the keyboard or a series of buttons to enter the host computer 1.

The computer host 1 includes a processor 110 and a memory 120. The memory 120 stores a driver 300, an operating system program 400, and an application program 500. The function that the driver 300 can achieve is The characteristics and focus of the invention.

The function of the selection device 80 is to allow only one of the input devices of the same type to operate the host computer 1, while the other input devices are unable to operate the host computer 1.

Next, please refer to FIG. 3 to FIG. 6 together to explain the method of controlling the complex input device of the present invention.

Step 301: Receive a plurality of standard format signals.

All complex standard format signals generated by all input devices 90a, 90b, 90c are received. This is the signal that would normally be generated by the general input devices 90a, 90b, 90c.

As shown in FIG. 4, the input devices 90a, 90b, 90c are mice, the input device 90a generates a standard format signal 201a, the input device 90b generates a standard format signal 201b, and the input device 90c generates a standard format signal 201c.

Step 302: Separate the plurality of standard format signals separately.

Each standard format signal is separated into an operation signal and a non-operational signal. Among them, the "operation signal" is a signal that can directly act on the host computer 1. For example, when the input device 90a, 90b, 90c is a mouse, the operation signal includes a cursor displacement signal generated by the actuation mouse, a left and right key press signal, a wheel control signal, etc.; when the input device 90a, 90b, 90c When it is a keyboard, the operation signal is the signal generated by pressing any button or a series of buttons on the keyboard. "Non-operational signal" is the general name of all signals except the operation signal in the standard format signal. For example, the non-operational signal includes an input device connection signal, so that the computer host 1 knows which input devices 90a, 90b, and 90c are currently electrically connected to the computer host 1.

As shown in FIG. 4, the driver 300 separates the standard format signal 201a into the operation signal 202a and the non-operation signal 203a, and separates the standard format signal 201b into the operation signal 202b and the non-operation signal 203b, and separates the standard format signal 201c into an operation signal. 202c and non-operation signal 203c.

Step 303: Obtain a specified input device message.

The designated input device message 204 is generated by the selection device 80 operating the general application 510 as a message for selecting a designated input device 90a, 90b or 90c from the plurality of input devices 90a, 90b, 90c.

In the embodiment of FIG. 4, the designated input device message 204 is that the designated input device 90c can actuate the computer host 1, and the input devices 90a, 90b cannot operate the computer host 1.

Referring to FIG. 5, there is shown a screen display embodiment of a designated input device, wherein the screen of FIG. 5 is generated by the selection device designation program 520. In the present embodiment, there are a total of 10 students, and the input device is a mouse. For example, when the teacher uses the selection device 80 to switch the "designated input device" to the Edward mouse, a "specified input device message" is generated. That means that only Edward's mouse can be manipulated, and the rest of the mouse cannot be operated.

The selection device 80 can be a keyboard (such as a standard keyboard or a small numeric keypad, etc.) or a device with a special toggle button. The teacher can operate the selection device 80 to switch the input device mastership to the designated student so that only the input device 90a, 90b or 90c to which the designated student belongs can be manipulated.

Step 304: The operation signal in the standard format signal of the plurality of input devices other than the input device is removed to be a plurality of non-designated signals; and the operation signal and the non-operation signal corresponding to the designated input device are combined to become the designated signal.

As shown in FIG. 4, the operation signals 202a, 202b generated by the input devices 90a, 90b are removed, and the non-operation signals 203a, 203b generated by the input devices 90a, 90b are still retained, and finally the non-designated signals 205a are formed, respectively. 205b. Since the input device 99c is a designated input device, the operation signal 202c and the non-operation signal 203c generated by the input device 90c are completely retained, and the operation signal 202c and the non-operation signal 203c are combined to become the designated signal 206.

Step 305: Output a plurality of non-designated signals and designated signals.

As shown in FIG. 5, the plurality of non-designated messages 205a, 205b and the designated signal 206 are output to the operating system program 400. Since the plurality of non-designated messages 205a, 205b and the designated signal 206 are still in the standard format signal, the operating system program 400 can still correctly interpret and perform subsequent operations. The operating system program 400 can be a commonly used operating system program (for example, a Windows operating system).

Due to the relationship of the designated signals 206, only the operational signals 202c can be transmitted to the operating system program 400 among all of the operational signals 202a, 202b, 202c, and then only the operating device 90c can operate the general application 510. In the present specification, the general application 510 refers to a general application such as a game software, an educational software, a document software, a Microsoft office software, and a browser software.

Due to the relationship of the non-designated signals 205a, 205b, the host computer 1 can still know that all of the input devices 90a, 90b, 90c are still connected. In the embodiment shown in Figures 5~~6, even if only the Edward mouse can be manipulated, the remaining mice are still connected to the host computer 1 (Figure 6 shows 10 C.-S.SHIH's Mouse Driver) Therefore, there are still 10 mouse connections in the device administrator. This is different from the traditional control box in Figure 1. If the traditional control box of Figure 1 is used, there are 10 mice connected to the computer. Line, but only see a mouse driver (Mouse Driver).

In summary, the method for controlling a plurality of input devices, a computer host, a computer system, and a computer readable recording medium thereof according to the present invention are in a software switching manner, and not all communication devices of all input devices other than the designated input device are turned off, but The non-operational signals of the non-designated input devices are still retained, and the communication between all the input devices and the host computer is not cut off, and is still connected. Therefore, when the software switch is switched, the hardware switch is not required to continuously perform the disconnection and reconnection, thereby greatly improving the efficiency of switching between the plurality of input devices, and there is no difference between the input devices. Signal interference problem.

In summary, the present invention exhibits features that are different from conventional techniques in terms of purpose, means, and efficacy. It is to be noted that the above-described embodiments are merely illustrative of the principles of the invention and its advantages, and are not intended to limit the scope of the invention.
