[Input device embodiment that can be switched between multiple computers]

Please refer to FIG. 1. FIG. 1 is a schematic diagram of an embodiment of an input device that can be switched between multiple computers according to the present invention.

In this embodiment, the input device can be a wireless mouse 10. The wireless keyboard 12 may be further included in addition to the wireless mouse 10 to constitute an input device group. The input device group composed of the mouse 10 and the keyboard 12 can wirelessly transmit the input command to the first computer 20 or the second computer 22 by using a wireless communication technology (such as Bluetooth communication technology), so as to control multiple computers by using one set of input devices. Effect.

The first computer 20 in this example includes a first host 20a and a first screen 20b, wherein the first host 20a is further provided with a first dongle 200 for receiving signals from the input device. The second computer 22 includes a second host 22a and a second screen 22b, and a second receiver 220 is disposed at the second host 22a. Further, as shown in FIG. 1, the position of the first screen 20b in this example is located to the left of the second screen 22b.

Taking the mouse 10 as an input device as an example, assuming that the controlled computer controlled by the mouse 10 is the first computer 20, when the mouse 10 moves, the first host 20a accepts and executes the input command of the mouse 10, and The control screen moves on the first screen 20b in accordance with the direction and distance in which the mouse 10 moves. When the user wishes to change from controlling the first computer 20 to controlling another computer, such as the second computer 22, the mouse 10 can be moved largely toward the first index direction d ₁ corresponding to the first screen 20b (in the present In the example, the mouse 10 is moved to the right), so that the controller of the mouse 10 (not shown in FIG. 1) determines the computer to be controlled according to the amount of movement and the direction of movement, and then changes the output to control the second. Upon input of the computer 22, the second host 22a will receive an input command by the second receiver 220 and display an indicator on the second screen 22b to correspond to the operation of the input mouse 10. On the other hand, if the user again wishes to control the first computer 20 with the mouse 10, the mouse 10 can be oriented toward the first direction d ₂ corresponding to the second screen 22b (in this example, the mouse 10 is left) The movement is greatly moved, and the controller of the mouse 10 is again issued an input command for controlling the first computer 20 in accordance with the amount of movement and the direction of movement.

Wherein, when the keyboard 12 and the mouse 10 cooperate to function as input devices of the plurality of computers 20 and 22, the controller of the keyboard 12 (not shown in FIG. 1) can follow the setting of the mouse 10, and can be switched synchronously with the mouse 10 and Operates on the same computer. In other words, when the keyboard 12 transmits the keyboard input command, it may include the same identification code as the input command of the mouse 10, so that the input command from the mouse 10 and the keyboard input command of the keyboard 12 are received by the same computer.

The input device achieves an implementation method that can be switched between multiple computers. Please refer to FIG. 2 for further explanation.

2 is a block diagram of an embodiment of an input device of the present invention that can be switched between multiple computers. The input device 30 includes a sensing unit 300, a control unit 302, a storage unit 304, and a transmission unit 306. The sensing unit 300, the storage unit 304, and the transmission unit 306 are electrically connected to the control unit 302, respectively. The input device 30 can be a device such as a mouse or a touchpad.

The sensing unit 300 is configured to sense a change in displacement of the input device 30 caused by an operation of a user. For example, the sensing unit 300 can be an optical sensing module disposed at the bottom of the mouse for detecting the input device 30 in the vertical direction (y-axis) according to different patterns generated by the light reflection. The displacement in the horizontal direction (x-axis) changes.

The control unit 302 can receive the displacement change detected by the sensing unit 300 to calculate the displacement direction and the displacement amount of the input device 30. In particular, control unit 302 can process a wafer for a microcontroller (MCU), an embedded controller (EC), and the like. In the present embodiment, the displacement direction calculated by the control unit 302 may be one of a horizontal direction or a vertical direction of the input device 30, and the displacement direction may include a first moving direction and a second moving direction. For example, when the displacement direction is the horizontal direction, the first moving direction and the second moving direction may respectively be a direction in which the horizontal coordinate value increases and a direction in which the horizontal coordinate value decreases. When the displacement direction is the vertical direction, the first moving direction and the second moving direction may respectively be a direction in which the vertical coordinate value is increased and a direction in which the vertical coordinate value is decreased. The amount of displacement may be the coordinate difference between the starting point and the stopping point of the input device 30 moving in the displacement direction, for example, the numerical value of the horizontal (x-axis) coordinate value.

The direction of the displacement of the input device 30 may correspond to the direction of the first indicator and the direction of the second indicator of the computer, for example, the first direction of movement corresponds to the direction of the first indicator, and the direction of the second direction corresponds to the direction of the second indicator; or A moving direction corresponds to the second index direction, and the second moving direction corresponds to the first index direction.

After the control unit 302 calculates the displacement direction and the displacement amount of the input device 30, an input command can be generated according to the displacement direction and the displacement amount for transmission to the controlled computer. In addition to the displacement direction and bit in the input command In addition to the shift amount, instructions for controlling the computer, such as a click command generated by pressing a mouse button or a scroll command generated by rotating the scroll wheel, may be included. In addition, since the input device 30 of the embodiment is shared by the plurality of computers 40 and 42 , the input command includes the identification data of one of the computers to be controlled by the input device 30, such as a set of identification codes. The computer 40, 42 receiving the input command determines whether the input command should be executed.

The storage unit 304 can be used to store identification codes of respective computers sharing the input device 30. The storage unit 304 can be a variety of memory chips, wherein the memory chip can be, for example, a non-volatile memory chip such as a flash memory in order to store the recorded identification code for a long time. Each computer sharing the same input device 30 has an independent and unique identification code and is recorded in the storage unit 304.

The transmission unit 306 is configured to transmit the input finger command generated by the control unit 302 to each computer of the shared input device 30, that is, the first computer 40 and the second computer 42 in this example, and are respectively configured by the first computer 40. A receiver 400 and a second receiver 420 of the second computer 42 receive the input command. The transmission unit 306 can be a wireless signal transmission module, such as a Bluetooth module chip or an infrared module chip. The first receiver 400 and the second receiver 420 may include a wireless signal receiving module corresponding to the transmitting unit 306 to receive the input command.

The first receiver 400 and the second receiver 420 respectively determine whether the input instruction should be transmitted to the corresponding processor for parsing and execution according to the identification code included in the input instruction. When the identification code included in the input command is the identification code of the first computer 40, the first receiver 400 transmits the input command to the first processor 402, so that the first computer 40 becomes the input device. Set the 30 controlled computer. When receiving the input command, the first processor 402 can perform the position of the indicator on the mobile screen (not shown in FIG. 2), open the file or scroll according to the displacement direction, the displacement amount, the click command or the scroll command, etc. among the input commands. Work on the web page, etc. When the second receiver 402 compares the identification code in the input command with the identification code of the second computer 42, and further determines that the input command is not used to control the second computer 42, the input command does not It is transmitted to the second processor 422 for execution, at which time the second computer 42 is not a computer under control by the input device 30.

Thereby, the first computer 40 and the second computer 42 can share the same input device 30, and can be controlled by the input device 30 to input only one of the computers at the same time, avoiding other The computer has a conflicting effect.

In particular, in the present embodiment, when the input device 30 is to switch the computer to be controlled, it is determined whether the input device 30 is switched to another computer by using the moving amplitude and direction of the input device 30, and which one should be switched to. Computer. The first moving direction and the second moving direction of the input device 30 respectively correspond to the moving direction of the index of the controlled computer. The control unit 302 can determine whether the displacement direction of the input device 30 is the first index direction corresponding to the computer currently being controlled (for example, the first computer 40), and whether the displacement amount corresponding to the direction of the first index is greater than a preset. The threshold value.

Referring to FIG. 3 together, FIG. 3 illustrates a first computer 40 and a first screen 40a, and a second computer 42 and a second screen 42a disposed on the right side of the first screen 40a. The origin of each screen coordinate is the upper left vertex of the screen, the horizontal coordinate (x-axis) extends to the right from the origin, and the vertical coordinate (y-axis) extends downward from the origin.

Since the first screen 40a and the second screen 42a are arranged side by side in the lateral direction, Therefore, in the embodiment shown in FIG. 3, the horizontal displacement change of the input device 30 can be used to determine the computer to be controlled to conform to the user's operating habits and intuition. Therefore, in this example, the control unit 302 only needs to calculate the horizontal displacement change. In order to comply with the user's operating habits, the first indicator direction 50 of the first computer 40 is in the right direction (when facing the first screen 40a) and faces the second screen 42a, and the second indicator is opposite to the first indicator direction 50. Direction 52 is left. On the other hand, the first index direction 54 of the second computer 42 is directed to the first screen 40a in the left direction, and the second index direction 56 opposite to the first index direction 54 is in the right direction.

It is assumed that the first moving direction 32 of the input device 30 corresponds to the first index direction 50 of the first computer 40 and is all rightward, and the second moving direction 34 corresponds to the second index direction 52 and is leftward. When the input device 30 moves in the first moving direction 32, the processor of the first computer 40 also controls the index on the first screen 40a to move toward the first index direction 50. In addition, the first moving direction 32 of the input device 30 may correspond to the second index direction 56 of the second computer 42 to the right, and the second moving direction 34 corresponds to the first index direction 54 of the second computer 42 and All are left.

Thereby, when the user wants to switch the input device 30 from the controlled computer (ie, the first computer 40 in this example) to another computer (ie, the second computer 42 in this example), the first The computer 40 is still in a controlled state, moving the input device 30 toward the first direction of movement 32 and causing the magnitude of the movement to be greater than the threshold value. The control unit 302 (refer to FIG. 2) can calculate the moving direction and distance of the input device 30 according to the sensing unit 300 sensing the amount of change in the movement of the input device 30. When the moving direction of the input device 30 is the first moving direction 32 (for example, it is determined to move to the right according to the increase of the x-axis coordinate value), the control unit 302 further accumulates the continuous orientation toward the first indicator. The displacement amount of the direction 50 movement is the first accumulation amount, and is compared with whether the first accumulation amount is greater than a threshold value. The threshold value may be a value preset and stored in the storage unit 304, for example, a value greater than the maximum screen resolution of each computer of the shared input device 30, such as 3000 pixels. When the first accumulated amount is greater than the threshold value, the user performs a large movement on the input device 30 in the first index direction 50 toward the first computer 40, and the control unit 302 determines that the input device 30 is to be switched to the second computer. Control is performed on 42.

When the control unit 302 determines that the input device 30 should be switched to another computer (the second computer 42 in this example), the identification code of the second computer 42 can be added to the input command according to the data stored in the storage unit 304. And transmitted to the plurality of computers 40, 42 through the transmission unit 306. The second computer 42 can receive and execute the input command by recognizing the identification code in the input command.

Further, if the control unit 302 determines that the input device 30 moves toward the first moving direction 32 corresponding to the first index direction 50 when the input device 30 acts on the first computer 40, the accumulated first accumulated amount is not greater than the threshold value, or When the input device 30 moves toward the second moving direction 34 corresponding to the second index direction 52 (that is, it is determined to be moved to the left according to the decrease of the y-axis coordinate value), the representative user does not intend to switch the controlled computer. Therefore, among the input commands generated by the control unit 302, the added identification code will be maintained as the identification code corresponding to the first computer 40, so that the first computer 40 receives and executes the input command transmitted by the input device 30 according to the identification code.

Wherein, when the input device 30 acts on the first computer 40, the input device 30 may repeatedly move between the first index direction 50 and the second index direction 52 according to the needs of the user operation. In this case, in order to prevent the input device 30 from moving toward the second index direction 52, the control The unit 302 mistakenly accumulates the displacement amount corresponding to the second index direction 52 as the first accumulation amount, and therefore, when the control unit 302 determines that the input device 30 moves toward the second movement direction 34 corresponding to the second index direction 52, the accumulated The first accumulated amount will be cleared. For example, the first accumulated amount of the temporary register temporarily stored in the storage unit 304 or the control unit 302 is zeroed. In this way, only when the user moves to the first moving direction 32 (ie, corresponding to the first indicator direction 50 of the first computer 40) to move beyond the threshold value, the switch to the second computer is generated. The effect of 42. The effect displayed on the screen is such that the indicator is displayed across the first screen 40a to the second screen 42a.

On the other hand, taking the second computer 42 as a controlled computer as an example, when the input device 30 acts on the second computer 42 and transmits an input command to control the second computer 42, the control unit 302 determines that the input device 30 is oriented. When the second moving direction 34 corresponding to the first index direction 54 of the second computer 42 moves, and the first accumulated amount accumulated continuously moving toward the first index direction 54 is greater than the threshold value, the control unit 302 also determines the input device. 30 should be switched to another computer for control of the other computer (i.e., the first computer 40 in this example). Thereby, the indicator moves from the second screen 42a to the left until it is displayed across the first screen 40a. On the contrary, when the first accumulated amount of the input device 30 moving toward the first index direction 54 is not greater than the threshold value, or the input device 30 moves toward the second index direction 56, the control unit 302 determines that the input device 30 is still used for the control. The second computer 42, and in turn generates an input command with the identification code of the second computer 42, to facilitate the second computer 42 to accept the command and execute.

[Another embodiment of an input device that can be switched between multiple computers]

The input device 30 can switch across multiple computers to make the indicator span horizontally In addition to the aligned screens, the indicators can be cross-displayed across the vertically aligned screens. Referring to FIG. 4, FIG. 4 illustrates a first screen 40a arranged longitudinally and a second screen 42a disposed below the first screen 40a, which are respectively connected to the first computer 40 and the second computer 42.

Please refer to the block diagram shown in Figure 2. The control unit 302 can determine, according to the displacement direction and the displacement amount sensed by the sensing unit 300, that the input device 30 controls the first computer 40 or the second computer 42, and further corresponds to the first screen 40a or the second screen. Indicators are displayed on 42a. In this embodiment, since the pendulum of the screen is arranged in a vertical direction, the control unit 302 can determine the input device 30 by calculating the vertical (y-axis) direction displacement change of the input device 30 in order to conform to the user's operating habits and intuition. Controlled computer. In other words, in the present embodiment, the control unit 302 can determine the first moving direction 36 in which the input device 30 moves backward, and the second moving direction 38 in the forward movement.

As shown in FIG. 4, the first indicator direction 60 of the first computer 40 can be the direction in which the y-axis coordinate value of the first screen 40a is increasing to point to the second screen 42a and corresponds to the first direction of movement 36 of the input device 30. The second index direction 62 is the direction in which the y-axis coordinate value is decremented and corresponds to the second moving direction 38 of the input device 30. In contrast, the first indicator direction 64 of the second computer 42 may be the direction in which the y-axis coordinate value of the second screen 42a is decremented to point to the first screen 40a, and corresponds to the second movement direction 38 of the input device 30, the second indicator. The direction 66 is the direction in which the y-axis coordinate value of the second screen 42a is increasing, and corresponds to the first moving direction 36 of the input device 30.

When the input device 30 acts on the first computer 40 (controlled computer) and moves backward, the control unit 302 can determine that the vertical displacement direction of the corresponding input device 30 is the first moving direction 36 and calculate the displacement amount thereof. control unit The displacement amount of the 302 accumulative input device 30 corresponding to the first index direction 60 is the first cumulative amount, and compares whether the first accumulated amount is greater than the threshold value to determine whether the user wants to input the input device 30 from the first computer 40. Switch to another computer, which is the second computer 42 shown in FIG. When the input device 30 acts on the second computer 42, when the input device 30 moves forward, the control unit 302 can calculate the displacement direction of the input device 30 as the second moving direction 38, so that the corresponding control index is on the second screen 42a. The upper direction moves toward the first index direction 64, and the displacement amount generated corresponding to the movement of the first index direction 64 is calculated as the first cumulative amount.

When the first accumulated amount is accumulated to exceed the threshold, the control unit 302 determines that the input device 30 should be switched to operate on another computer, and determines the input when the first accumulated amount does not reach the threshold value or is calculated by the control unit 302. When the displacement direction of the device 30 corresponds to the second index direction of the active computer, the input device 30 is not switched to another computer.

Other features of the input device 30 in this embodiment are the same as or similar to those in the previous embodiment. Please refer to the description of the previous embodiment, which will not be repeated here.

[An input device that can be switched between multiple computers.]

Please refer to FIG. 5. FIG. 5 is a schematic diagram of another embodiment of an input device that can be switched between multiple computers. The difference from the embodiment shown in FIG. 3 is that the third computer 44 and the third screen 44a are further disposed in the embodiment, and the third screen 44a is placed on the horizontally adjacent first screen 40a and second screen 42a. between. Please refer to the block diagram of the embodiment of the input device 30 shown in FIG.

In this embodiment, taking the third computer 44 as the controlled computer as an example, the first moving direction 32 and the second moving direction 34 of the input device 30 are equally separable. The first indicator direction 58 and the second indicator direction 59 of the third computer 44 are not corresponding. The first indicator direction 58 is directed toward the second screen 42a disposed to the right of the third screen 44a, and the second index direction 59 is directed toward the first screen 40a disposed to the left of the third screen 44a. When the input device 30 operates on the third computer 44, the control unit 302 can determine that the index on the third screen 44a moves toward the first index direction 58 according to the calculated first moving direction 32, and accumulates toward the first index direction. The displacement amount of 58 movement is the first cumulative amount. When the first accumulated amount is greater than the threshold value, the control unit 302 may decide to switch the input device 30 to another computer. In order to comply with the user's operating habits, the control unit 302 may decide to switch the input device 30 to the second computer 42 to control and input the second computer 42 so that the indicators on the second screen 42a start to function.

On the other hand, if the control unit 302 determines that the index of the third screen 44a moves toward the second index direction 59 according to the calculated second moving direction 34, the amount of displacement that is moved toward the second index direction 59 is second accumulated. the amount. When the control unit 302 compares the threshold value with the second accumulated amount and determines that the second accumulated amount is greater than the threshold value, it also determines that the input device 30 should switch to another computer. In the present embodiment, the input device 30 is switched to the first computer 40 so that the indicators on the first screen 40a can start to function.

It is worth mentioning that, in order for the control unit 302 to correctly correspond to the computer to be switched, the storage unit 304 in this example may further record the first indicator direction of each of the plurality of computers sharing the same input device 30. A flag corresponding to the direction of the second indicator for the control unit 302 to determine the computer to be switched. For example, the first identifier corresponding to the first indicator direction 50 of the first computer 40 indicates the third computer 44, and the first identifier corresponding to the first indicator direction 54 of the second computer 42 also indicates the third computer 44. The first identifier corresponding to the first indicator direction 58 of the third computer 44 indicates the second computer 42, and the second identifier corresponding to the second indicator direction 59 of the third computer 44 indicates the first computer 40. Thereby, when the control unit 302 calculates that the input device 30 is moving toward the first indicator direction or the second indicator direction of the active computer, the control unit 302 can know that the input device 30 should be switched to the correct other computer according to the corresponding identifier. Working on. The identification may be recorded in the form of a look-up table for reference by the control unit 302.

In order to prevent the control unit 302 from accumulating the displacement amounts in different directions, in the above embodiment, when the input device 30 moves toward the first index direction 58, the control unit 302 divides the previous accumulated amount and The accumulated second cumulative amount is cleared. Conversely, when the input device 30 moves toward the second index direction 59, the control unit 302 clears the previously accumulated first accumulated amount in addition to the accumulated second accumulated amount.

By recording the identification of the computer corresponding to the first indicator direction and the second index direction of each computer, when the plurality of computers exceeds two, the control unit 302 of the input device 30 can still correctly judge the user toward After the input device 30 is largely moved in a certain direction, which computer the input device 30 should be switched to.

In particular, in other implementations, the means for determining that the input device 30 switches from one computer to another may be accomplished by other means in addition to recording the identifier corresponding to each indicator direction. For example, a plurality of threshold values may be set according to a relative positional relationship between each computer screen and other computer screens, and then the control unit 302 calculates different threshold values that the cumulative amount of movement of the input device 30 satisfies, and switches the input device 30 to a different one. Working on the computer. Referring to FIG. 5 , for example, a threshold of two stages can be set for the first indicator direction 50 of the first computer 40, which is the first threshold and the first threshold. The two thresholds assume that the first threshold is greater than 3000 pixels and the second threshold is greater than 6000 pixels.

When the input device 30 operates on the first computer 40 and continuously moves in the first moving direction 32, the control unit 302 may calculate a first accumulated amount that moves toward the first index direction 50, and determine whether the first accumulated amount exceeds The second threshold value, if the first accumulated amount exceeds the second threshold value, that is, the input device 30 moves over a distance of more than 6000 pixels at a time, it is determined that the input device 30 is switched to another computer farther away (in this example, the second Computer 42) operates. If the first accumulated amount does not exceed the second threshold, it is determined whether the first threshold value is exceeded. When the first accumulated amount is between the first threshold and the second threshold, the control unit 302 determines that the input device 30 is switched from the first computer 40 to another computer (in this example, the third computer 44) ) Operation.

Similarly, if the second computer 42 is used as the controlled computer, the first threshold and the second threshold may be set to be compared with the first accumulated amount corresponding to the first indicator direction 54. When the first accumulated amount corresponding to the first indicator direction 54 is greater than the second threshold, it is determined that the input device 30 is switched from the second computer 42 to another computer (the first computer 40) that is farther away; When it is between the first threshold and the second threshold, it is judged that the input device 30 is switched from the second computer 42 to another computer (third computer 44) that is closer.

Thereby, by using the cumulative amount in the same direction to compare the multiple threshold values, the displacement amount of the movement of the input device 30 can also be switched to a different computer for input control when the different threshold conditions are met. In vernacular terms, the greater the amplitude of the single movement of the input device 30 in the same direction, the more likely the indicator is to exhibit the effect of moving across a plurality of screens over a relatively distant screen. The threshold value may also be pre-stored in the storage unit 304 for the control unit 302. The calculation is performed by reading the comparison, or directly setting the value in the program, for the control unit 302 to judge.

Through the description of the above embodiments, the input device provided by the present invention can be switched not only between a plurality of computers corresponding to the horizontally arranged screens, but also between a plurality of computers corresponding to the vertically arranged screens, through the same principle.

[Example of Method of Input Device Controlling Multiple Computers]

Please refer to FIG. 6 for a flow chart of an embodiment of the input device control multi-computer, and please refer to the block diagram illustrated in FIG. 2 and the schematic diagram illustrated in FIG. 3 . The input device 30 of the present embodiment can be operated on one of the computers at the same time after being connected to a plurality of computers (such as the first computer 40 and the second computer 42 shown in FIG. 2) by wireless transmission. To control the computer (for example, the first computer 40 is preset as a controlled computer) (S701). The control unit 302 of the input device 30 can calculate the displacement direction and the displacement amount of the input device 30 according to the displacement change sensed by the sensing unit 300 (S703). The displacement direction of the input device 30 may include a first movement direction 32 and a second movement direction 34, and respectively correspond to the first index direction 50 and the second index direction 52 of the first computer 40. Therefore, when the input device 30 moves toward the first moving direction 32, the index on the first computer 40 will move toward the first index direction 50. The control unit 302 can determine whether the input device 30 is moved toward the first index direction 50 corresponding to the first computer 40 based on the calculated displacement direction (S705). In the present embodiment, the displacement direction of the input device 30 may be a horizontal direction.

If the displacement direction of the input device 30 corresponds to the first index direction 50 of the first computer 40, the control unit 302 may further accumulate the input device 30 continuously toward The displacement amount corresponding to the movement corresponding to the first index direction 50 is the first accumulation amount (S707), and it is judged whether or not the first accumulation amount is larger than the threshold value (S709). The threshold value may be a value pre-stored in the storage unit 304, for example, a pixel value greater than the screen resolution of any computer connected to the input device 30. If the first accumulated amount accumulated by the input device 30 moving toward the first index direction 50 is not greater than the threshold value, the control unit 302 can determine that the user maintains the first computer 40 controlled by the input device 30 described. At this time, the control unit 302 can generate an input command to the controlled computer (ie, the first computer 40), and the input command includes the identification code of the first computer 40 (S711). Therefore, when a plurality of computers connected to the input device 30 receive the input command transmitted through the transmission unit 306, only the first computer 40 whose identification code matches will execute the input command, and the control device 30 controls the input device 30. The effect of a computer 40. After the input command is generated and output, the control unit 302 may return to step S703 and continue to calculate the displacement direction and the displacement amount of the input device 30 according to the displacement change sensed by the sensing unit 300.

Further, after the step S709 determines the magnitude of the first accumulated amount and the threshold value, and confirms that the first accumulated amount is greater than the threshold value, the control unit 302 may determine that the input device 30 should be switched to among the plurality of computers connected thereto. Another computer (S713), which in this embodiment, can be a second computer 42 (see Fig. 3). When the control unit 302 decides to switch the input device 30 to the second computer 42 to control the second computer 42, another input command including the identification code of the second computer 42 may be generated for the first computer 40 and the second computer. When the input command is received, only the second computer 42 whose identification code matches will execute the input command and receive the control of the input device 30 (S715).

In another direction, when it is determined in step S705 whether the direction of displacement of the input device 30 is the first indicator direction 50 corresponding to the first computer 40, the result is no. The displacement direction of the input device 30 is oriented toward the second index direction 52 corresponding to the first computer 40. At this time, in order to prevent the control unit 302 from erroneously shifting the displacement of the input device 30 toward the second index direction 52, the first accumulation is counted. The result of the comparison between the first accumulated amount and the threshold is misjudged, so the control unit 302 can clear the first accumulated amount (S717), and returns to step S711 to generate an input command including the identification code of the first computer 40. For the first computer 40 to receive execution.

Similarly, when the input device 30 acts on the second computer 42, it is also possible to determine whether the user wants to change from controlling the second computer 42 to controlling the first computer 40 by performing the flow steps shown in FIG. 6. The control unit 302 only needs to first determine the correspondence between the index direction of the second computer 42 and the displacement direction of the input device 30, as shown in FIG. 3, the first index direction 54 corresponds to the second moving direction 34, and the second index. The direction 56 corresponds to the first moving direction 32.

[Another embodiment of a method of controlling a multi-computer by an input device]

Next, please refer to FIG. 7. FIG. 7 is a flow chart of another embodiment of a method for controlling a multi-computer by an input device according to the present invention. Please refer to the block diagram shown in FIG. 2 and the schematic diagram shown in FIG.

Similarly to the previous embodiment, the input device 30 can be wirelessly connected to a plurality of computers (in this example, a first computer, a second computer, and a third computer) and controlled each time on one of the computers (for example, The third computer is preset as the controlled computer) (S801). The control unit 302 can calculate the displacement direction and the displacement amount of the input device 30 according to the displacement change sensed by the sensing unit 300 (S803). The displacement direction of the input device 30 may include a first movement direction 32 and a second movement direction 34, and respectively correspond to the first index direction 58 and the second index direction 59 of the third computer. Therefore, when the input device 30 faces the first When a moving direction 32 moves, the indicator on the third computer will move toward the first indicator direction 58. The control unit 302 can determine whether the input device 30 is moved toward the first index direction 58 corresponding to the third computer based on the calculated displacement direction (S805). In the present embodiment, the displacement direction of the input device 30 may be a horizontal direction.

If the displacement direction of the input device 30 is moving corresponding to the first index direction 58 of the third computer, the control unit 302 may further accumulate the displacement amount of the input device 30 moving toward the first index direction 58 as the first cumulative amount, and also clear the input. The device 30 may move the accumulated second accumulated amount previously toward the second index direction 59 (S807) to avoid erroneously accumulating the amount of displacement that is not corresponding to the first index direction 58 as the first accumulated amount. The control unit 302 further compares whether the first accumulated amount is greater than a threshold value (S809), thereby determining whether the input device 30 is a large-scale movement. If the first accumulated amount is not greater than the threshold value, the control unit 302 can determine that the input device 30 continues to act on the third computer, so that an input command can be generated according to the user's operation on the input device 30, the input command The identification code of the third computer (S811) is included, so that after the plurality of computers receive the input instruction, only the third computer whose identification code matches will execute the content of the input instruction. After the input command is generated and output, the control unit 302 may return to step S803 and continue to calculate the displacement direction and the displacement amount of the input device 30 according to the displacement change sensed by the sensing unit 300.

After the step S809 of determining whether the first accumulated amount is greater than the threshold value, when the first accumulated amount is indeed greater than the threshold value, the control unit 302 may further determine whether there is an identifier of another computer corresponding to the first indicator direction 58 ( S813), for example, refer to the lookup table stored in the storage unit 306. For example, the identifier corresponding to the first indicator direction 58 of the third computer in the comparison table is the second The computer's identification code, however corresponding to the second indicator direction 52 of the first computer, identifies that there is no corresponding computer. Thereby, the control unit 302 can determine, according to the identifier, that the input device 30 should switch to another computer for control when the currently operated controlled computer (third computer) moves toward the first index direction 58 by a threshold greater than the threshold value. In this example, it is the second computer) (S815). The control unit 302 adds an identification code of the second computer when the input command is generated, so that the second computer receives the input command and executes it (S817). On the other hand, when it is determined that the input device 30 moves on one of the indicators toward one of the indicators and does not correspond to another computer after referring to the identification according to step S813, the input device 30 still functions on the same computer, and thus An input command including an identification code of the currently active computer is generated to control the original computer (S811).

On the other hand, when it is determined in step S805 whether the displacement direction of the input device 30 is the first index direction 58 corresponding to the third computer, the displacement direction of the input device 30 is oriented toward the second index corresponding to the third computer. Direction 59. At this time, the control unit 302 clears the first accumulated amount accumulated in step S807, and accumulates the displacement amount of the input device 30 moving toward the second index direction 59 as the second cumulative amount (S819). The control unit 302 further determines whether the second accumulated amount is greater than the threshold value (S821) to confirm whether the input device 30 is largely moved toward the second index direction 59.

If the second accumulated amount of the input device 30 moving toward the second index direction 59 is determined to be greater than the threshold value, the control unit 302 may also refer to the identifier in the look-up table to determine the controlled computer in the current operation (in this example After the third computer is moved largely toward the second index direction 59, there is another corresponding computer (S813). It is assumed that the identifier corresponding to the second indicator direction 59 of the third computer is the identification code of the second computer, and the control unit 302 Then, according to the identification, it is decided to switch the input device 30 to the second computer for control (S815), and generate an input command including the identification code of the second computer for the input device 30 to control the second computer (S817).

In addition, whether the first accumulated amount is greater than the threshold value and how to switch to another computer according to the result of the comparison can also be achieved by means of setting a multi-stage threshold. Taking the first computer 40 of FIG. 5 as an example, the threshold value for comparing the first accumulated amount of the first index direction 50 may be respectively set to a first threshold value corresponding to the third computer 44, for example, 3000 pixels, and Corresponding to the second threshold value of the second computer 42, for example, 6000 pixels.

When the input device 30 operates on the first computer 40, and the control unit 302 determines that the index moves toward the first index direction 50 according to the sensing of the sensing unit 300, the control unit 302 may first compare whether the calculated first accumulated amount is It is greater than the second threshold value, in other words, it is to judge whether the input device 30 moves laterally across the two screens. If the first accumulated amount is greater than the second threshold, the control unit 302 can switch the input device 30 to operate on the second computer 42 corresponding to the second screen 42a farther from the first screen 40a. On the other hand, if the first accumulated amount does not exceed the second threshold but is greater than the first threshold, the input device 30 is switched to operate on the third computer 44 corresponding to the third screen 44a that is closer to the first screen 40a.

Therefore, when the number of computers connected to the input device 30 is more than three, the control unit 302 can still determine the switching control of the input device 30 according to the index direction of the computer corresponding to the displacement direction of the input device 30 and the distance thereof. Another computer produces an input command with the correct identification code.

Although the computer and the screen arranged in the horizontal direction in FIG. 5 are taken as an example, when the screens of three or more computers are vertically arranged, the switching according to the displacement direction of the input device 30 can still be achieved according to the same principle. effect If it is not mentioned here.

[Another embodiment of an input device that can be switched between multiple computers]

Next, please refer to the schematic diagram of another embodiment of an input device that can be switched between multiple computers, as provided in FIGS. 8A to 8C.

FIG. 8A illustrates a first screen 90a, a second screen 92a, and a third screen 94a of the first computer to the third computer (not shown in FIG. 8A) of the input device. The three screens 90a to 94a are sequentially arranged on the same horizontal axis. Referring to the schematic diagram shown in FIG. 3, the first index direction 50 of the first screen 40a of FIG. 3 is the same as the second index direction 52, and the index direction on the first screen 90a of FIG. 8A is the horizontal index direction, including the orientation. The first lateral direction W1 of the second screen 92a and the second lateral direction W2 opposite the first lateral direction W1. As explained in the corresponding embodiment of FIG. 3, the control unit of the input device (not shown) can calculate the horizontal displacement direction of the input device and its displacement amount. When the horizontal displacement direction corresponds to the first lateral direction W1 and the cumulative horizontal accumulation amount continuously increases is greater than the horizontal threshold value A1, the input device is switched to operate on the second computer corresponding to the second screen 92a. When the horizontal displacement direction corresponds to the second lateral direction W2, the accumulated horizontal accumulation amount is cleared to avoid erroneously switching the computer operated by the input device.

Similarly, if the horizontal cumulative amount corresponding to the first horizontal direction W1 on the first computer is greater than twice the horizontal threshold A1 (ie, equivalent to A2 in FIG. 8A), the input device is switched from the first computer to the third. The third computer of the screen 94a.

The horizontal threshold value A1 in this example may be, for example, 3000 pixels, or any pixel larger than the maximum resolution of the horizontal axis of a single screen. Other related descriptions of the switching of the input device between the computers corresponding to the screens arranged on the same horizontal axis in the lateral direction have been described in detail in the foregoing embodiments and will not be repeated.

Referring to FIG. 8B, when the first screen 90b, the second screen 92b, and the third screen 94b are sequentially arranged on the same vertical axis from bottom to top, the index direction of the first screen 90b includes the first direction toward the second screen 92b. The longitudinal direction L1, and the second longitudinal direction L2 opposite to the first longitudinal direction L1.

As shown in FIG. 4, when the vertical displacement direction of the input device corresponds to the first longitudinal direction L1, and the vertical cumulative amount accumulated continuously toward the first longitudinal direction L1 is greater than the vertical threshold value B1, the input device is switched from the first computer. Go to the second computer corresponding to the second screen 92b. On the other hand, if the vertical displacement direction corresponds to the second longitudinal direction L2 movement, or the vertical accumulation amount moving toward the first longitudinal direction L1 is not greater than the vertical threshold value B1, the input device is not switched to other computers on the same vertical axis.

Similarly, if the vertical cumulative amount corresponding to the first longitudinal L1 cumulative movement on the first computer corresponding to the first screen 90b is greater than twice the vertical threshold value B1 (ie, B2 shown in FIG. 8B), the input device switches to It operates on the third computer corresponding to the third screen 94b.

The vertical threshold value B1 in this embodiment may be, for example, 2500 pixels, or any pixel larger than the maximum resolution of the vertical axis of a single screen. Other related descriptions of the switching of the input device between computers corresponding to the screens arranged longitudinally on the same longitudinal axis have been described in detail in the foregoing embodiments and will not be repeated.

Referring next to FIG. 8C, a schematic diagram of a plurality of screens positioned on different horizontal axes or different longitudinal axes is illustrated. The horizontal displacement direction 104 of the input device 100 may correspond to the first lateral direction and the second lateral direction of the first screen 90c, and the vertical displacement direction 102 may correspond to the first longitudinal direction and the second longitudinal direction of the first screen 90c. The first horizontal direction faces the third screen 94c on the same horizontal axis as the first screen 90c, and the first vertical direction faces the fourth screen 96c on the same vertical axis as the first screen 90c. The second screen 92c is in the same horizontal direction as the fourth screen 96c. The shaft is located on the same vertical axis as the third screen 94c.

When the input device 100 operates on the first computer of the first screen 90c, the direction of displacement of the input device 100 may include both a horizontal displacement direction and a vertical position direction. The control unit (not shown) of the input device 100 can calculate the displacement amount in the horizontal displacement direction and the displacement amount in the vertical displacement direction together. When the horizontal displacement direction corresponds to the first lateral direction and the vertical displacement direction corresponds to the first longitudinal direction, the control unit calculates whether the horizontal cumulative amount and the vertical cumulative amount are greater than the horizontal threshold value A1 and the vertical threshold value B1, respectively.

If only the horizontal accumulated amount is greater than the horizontal threshold A1, but the vertical accumulated amount is not greater than the vertical threshold B1, the control unit controls the input device 100 to be switched to the third computer of the third screen 94c on the same horizontal axis. (See the description of Figure 8A). In other words, the index of the input device 100 is originally displayed on the first screen 90c, and is displayed on the third screen 94c after moving in the P3 direction. On the other hand, if only the vertical accumulation amount is greater than the vertical threshold value B1, the input device 100 is switched to operate on the fourth computer of the fourth screen 96c on the same vertical axis (please refer to FIG. 8B), that is, After the P1 direction is moved, the indicator is displayed on the fourth screen 96c.

In particular, when the horizontal accumulation amount and the vertical accumulation amount are respectively greater than the corresponding horizontal threshold value A1 and the vertical threshold value B1, the horizontal displacement amount and the vertical displacement amount representing the input device 100 simultaneously generate a large change, so that the input device 100 is caused. The vertical direction (P1 direction) moves on the same horizontal axis as the fourth screen 96c, and moves in the horizontal direction (P3 direction) to be in the same vertical and horizontal direction as the third screen 94c, so that the indicator is finally moved in the P2 direction and from the first screen. The 90c is switched to display on the diagonally opposite second screen 92c.

In this example, the horizontal threshold A1 can also be any pixel that is greater than the maximum horizontal axis resolution of a single screen. And because there are more pixels on the horizontal axis of the general screen. The vertical axis pixel B1 can be any pixel larger than the maximum vertical axis resolution of the single screen and smaller than the horizontal threshold A1.

The control unit of the input device calculates the displacement direction and the displacement amount, and the means for accumulating the displacement amount or clearing the displacement amount according to the corresponding index direction has been described in the foregoing embodiment, and the same portion will not be repeated in this embodiment.
