Description

[0001] The invention relates to an input device and an operating method for the same, in particular an input device and an operating method which is suitable for use in a computer.

[0002] With advances in computer technology, modern people's lives are closely linked to computers. For example, using common input devices such as mice or keyboards, people can easily operate a computer device to perform tasks such as surfing the web, transferring money to someone else's account, checking with employment agencies, logging into social networking sites, or sending / receiving emails.

[0003] For most input devices, the sensitivity and transmission frequency are factory-set prior to delivery to suit general user needs. Depending on personal habits, users may operate input devices relatively quickly or slowly. However, general input devices operate with the same sensitivity and transmission frequency under different application programs, which can cause inconvenience when using general input devices.

[0004] Older people typically operate input devices at a slower speed, while younger people operate them at a faster speed. Therefore, it is necessary to adjust the sensitivity of the input devices based on personal requirements.

[0005] WO 2008 / 007295 A2 discloses an input device capable of responding to the operating state, comprising: an input unit capable of generating an input actuation signal; and a control unit connected to the input unit and sending an input actuation command to a computer based on the input actuation signal. The control unit analyzes the input actuation signal and, based on the analysis result, generates a setting command with which the input device can be converted from a currently used operating mode to a second operating mode. Another input device is known from DE 102 25 661 A1.

[0006] The invention is based on the object of creating an input device with the possibility of responding to the operating state and an operating method for this, which avoids the disadvantages mentioned above by simple measures.

[0007] This object is achieved according to the invention by an input device with the possibility of responding to the operating state, which has the features specified in claim 1, and by a method for responding to the operating state of an input device, which has the features specified in claim 6. Further advantageous developments of the invention emerge from the subclaims.

[0008] According to the invention, an input device with the possibility of responding to the operating state, comprising: an input unit capable of generating an input / actuation signal; and a control unit connected to the input unit and sending an input / operation command to a computer according to the input / operation signal, wherein the control unit analyses the input / actuation signal and generates a setting command according to the analysis result, with which the input device can be transferred from a currently used operating mode to a second operating mode.

[0009] According to the invention, a method suitable for responding to the operating state of an input device is provided, comprising the following steps: generating an input / operation signal through an input operation, the input / operation signal causing the input device to output an input / operation command to a computer; Analyzing the input / operation command; and Determining according to the analysis result whether a setting command is generated, whereby the setting command can transfer the input device from a currently used operating mode to a second operating mode.

[0010] In summary, according to the invention, the control unit of the input device is used to analyze the input / operation signal. Based on the analysis result, it is determined whether a setting command is generated. The setting command switches the input device from the currently used first operating mode to a second operating mode. The design described above can improve the convenience of operating the input device, effectively avoiding problems associated with inconvenient mouse operation due to age or application program limitations.

[0011] The invention and its embodiments are explained in more detail below with reference to the drawing. The drawing shows: Fig. 1 a perspective view of the system arrangement of an input device according to the invention with the possibility of responding to the operating state; Fig. 2 shows a functional block diagram of an embodiment of an input device according to the invention with the possibility of responding to the operating state; Fig. 3 a perspective view of the embodiment of an input device according to the invention with the possibility of responding to the operating state; Fig. 4 is a flowchart of an embodiment of a method according to the invention for responding to the operating state of an input device; Fig. 5 is a flowchart of a further embodiment of a method according to the invention for responding to the operating state of an input device; and Fig. 6 a flowchart of yet another embodiment of a method according to the invention for responding to the operating state of an input device.

[0012] In Fig. 1 and Fig. 2 shows a host computer 9, a display screen 8, a keyboard 7, and a mouse 1. In practice, the input device according to the invention is a wired keyboard, a wireless keyboard, a wired mouse, or a wireless mouse, with which the input of the host computer 9 or cursor control can be performed. To simplify the description, the mouse 1 is used as an example, to which the invention is not intended to be limited.

[0013] According to Fig. 2, the mouse 1 has an input unit 10, a control unit 12, an output unit 14, and a memory unit 16. A left / right mouse button, a mouse wheel, a displacement sensor, or a combination of these components can be selected as the input unit 10. When the input unit 10 is pressed, rolled, or moved, a corresponding input / actuation signal is generated and transmitted to the control unit 12. The input / actuation signal is a signal from the left / right mouse button, the mouse wheel, or the displacement sensor. The function of the input unit 10 is known per se and need not be explained in detail here.

[0014] The output unit 14 is designed, for example, as a high-frequency transmitter and ensures the reception of the input / operation command transmitted by the control unit 12 and the transmission of the input / operation command to the main computer 9. The input / operation command forces the main computer 9 to execute a corresponding command. Alternatively, the output unit 14 can be designed as a wired transmitter, to which the invention is not intended to be limited.

[0015] The control unit 12 is connected to the input unit 10, the output unit 14, and the memory unit 16. A central processing unit (CPU) or a microprocessor, for example, can be selected as the control unit 12 to perform the calculation and processing of the signals transmitted between all units within the mouse. In practice, the control unit 12 receives the input / operation signal and then generates an input / operation command. The control unit 12 then sends the input / operation command to a computer via the output unit 14.

[0016] The storage unit 16 is embodied, for example, as a non-volatile memory such as a flash or EEPROM memory. In practice, the storage unit 16 serves to record the input / operation signal. At least a predetermined number of times are stored in the storage unit 16. For example, a plurality of predetermined numbers of times are stored. When the cumulative number of times the input / operation signal is received reaches a predetermined number, the control unit 12 can generate a setting command. The quantity of the predetermined number of times stored by the storage unit 16 is not limited in this embodiment.

[0017] Note that the control unit 12 can analyze the input / operation signal and generate a setting command based on the analysis result. Based on the setting command, the mouse can be switched from the currently used first operating mode to a second operating mode. In practice, the analysis of the input / operation signal performed by the control unit 12 involves determining whether the number of times the input / operation signal is received reaches a predetermined number. If so, the control unit 12 generates the setting command.

[0018] For example, the memory unit 16 stores three predetermined numbers of times (e.g., 1,000, 5,000, and 10,000) that the input / operation signal is received. If the input unit 10 is actually pressed up to 1,000 times, the control unit 12 analyzes the 1,000 repeated input / operation signals. For example, if a user presses the input unit 10 ten times in one minute, the input / operation signals received 1,000 times are those generated at intervals of 6 seconds. Based on the analysis result, the control unit 12 generates the first setting command. This command transfers the input device from the first operating mode to the second operating mode.

[0019] If the control unit 12 determines that the cumulative number of times the input / operation signal is received reaches the predetermined number, the control unit 12 generates the setting command to immediately transition the first operation mode to the second operation mode. For example, three numbers [e.g., 1000, 5000, and 10000] of times the input / operation signal is received are stored in the storage unit 16. If the input unit 10 is actually pressed up to 1000 times, the control unit 12 generates the first setting command, which immediately transitions the mouse 1 to the second operation mode. If the input unit 10 is actually pressed up to 1000 or 5000 times, the control unit 12 generates the second / third setting command, which immediately transitions the mouse 1 to the third / fourth operation mode.

[0020] Otherwise, the control unit 12 may determine whether the number of times the input / operation signal is received within a predetermined period of time reaches a predetermined number of times. If so, the control unit 12 generates the setting command. The predetermined period of time may be selected from ten hours, one day, one week, or one month, to which the invention is not intended to be limited. If the input unit 12 determines that the cumulative number of times the input / operation signal is received within the predetermined period of time reaches the predetermined number, the control unit 12 generates the setting command, which immediately transitions the first operating mode to the second operating mode. In this embodiment, the predetermined period of time and the predetermined number of times are not limited.

[0021] In the first operating mode, for example, the input / operation command is output at the first transmission frequency, while in the second operating mode, the input / operation command is output at the second transmission frequency. The first transmission frequency can be greater than / less than, equal to / not equal to the second transmission frequency. The transmission frequency is, for example, the frequency at which mouse 1 sends the input / operation command to the computer when the input unit 10 of mouse 1 is pressed.

[0022] For example, the first transmission frequency of mouse 1, which is adapted for normal users, is 125 Hz. If the user plays a computer game with mouse 1 and is recognized as a game player through the aforementioned 1,000-time input / operation signal analysis, the control unit 12 generates the setting command according to the analysis result, which switches mouse 1 from the first operating mode to the second operating mode. In the second operating mode, the second transmission frequency, adapted for game players, is used, which is, for example, 250 Hz. In this embodiment, the numerical value of the first and second transmission frequencies is not limited.

[0023] If the input unit 10 is actually pressed up to 5,000 or 10,000 times, the control unit 12 analyzes the input / operation signal input 5,000 or 10,000 times. For example, the control unit 12 can generate the second or third setting command if the user habitually presses the input unit 10 20 or 30 times per minute. In this way, the current second operating mode transitions to the third operating mode. Otherwise, the current third operating mode can transition to the fourth operating mode.

[0024] In the first, second, third, and fourth operating modes according to the embodiment, the input / operation command is output on the first, second, third, or fourth transmission frequency. According to another embodiment, a first, second, third, and fourth key input response speed may be provided for the first, second, third, and fourth operating modes, respectively. The first, second, third, and fourth key input response speeds are the sensitivity of the mouse 1. For example, the average movement distance of the cursor can be determined according to the movement of the mouse displacement sensor, the average rolling distance by rolling the mouse wheel when surfing the Internet, or the average movement angle of the cursor can be determined according to the movement angle of the mouse displacement sensor.In this embodiment, the first, second, third and fourth modes are not limited in content.

[0025] If the user is just starting to use the mouse and is unfamiliar with the mouse's sensitivity, mouse clicks may malfunction. In this case, initial parameters such as the transmission frequency and sensitivity can be adjusted to suit the individual needs of the mouse novice. When the mouse 1 is clicked the set number of times, the mouse 1 can generate the setting command and reset the operating mode according to the user's mouse operation habits, so that the user will not find it difficult to operate the mouse. In other words, the mouse 1 can better meet user needs.

[0026] For example, the user can adjust the scrolling distance on the display screen when rolling the mouse wheel according to their operating habits. The cursor movement distance when moving the mouse 1 can also be adjusted according to the user's mouse operating habits. The transmission frequency of the input / operation command can also be adjusted according to the user's mouse operating habits by adjusting the left or right mouse button pressing frequency.

[0027] It should be noted that in other embodiments, the control unit 12 may determine whether the number of times the input / operation signal is received within a predetermined period of time reaches a predetermined number of times. If so, the control unit 12 generates the setting command. In practice, the control unit 12 may analyze the input / operation signal by determining whether the input / operation signal is a trigger signal. If the input / operation signal is judged to be a trigger signal, the subsequent input / operation signals after the trigger within a predetermined time are analyzed by the control unit 12 to generate a setting command.

[0028] In practice, the mouse 1 has a timing unit (not shown) connected to the control unit 12. For example, it can be set so that the trigger signal is generated when the mouse 1 is held down for up to five seconds. If the control unit 12 determines that the input / operation signal is a trigger signal, the control unit 12 activates the analysis of the subsequent input / operation signal within a predetermined time so that the control unit 12 generates the setting command. In this way, the user can activate the analysis of the subsequent input / operation signal at any time using the trigger signal to set the operating mode of the mouse 1. In this embodiment, the embodiment of the trigger signal is not limited.

[0029] As an example, let us further cite that elderly people operate mouse 1 slowly when processing words. If the left or right mouse button is pressed more than 1,000 times, the control unit 12 can analyze the input / operation signals entered 1,000 times. The input / operation signal entered 1,000 times represents a low operation frequency and a slow click speed, resulting in a setting command with which mouse 1 is set to an operating mode adapted to the elderly people. In this case, the transmission frequency of mouse 1 can be 75 Hz. This is known per se and therefore needs no further explanation. This is known per se and therefore needs no further explanation here.

[0030] It should be noted that the setting command is intended for adjusting the left mouse button sensitivity, the right mouse button sensitivity, the mouse wheel sensitivity, the mouse movement sensitivity, the mouse movement sensitivity, the transmission frequency, or a combination of these elements. For example, if the setting command is intended for adjusting the left mouse button, the transmission frequency of the input / operation command sent to the host computer 9 by pressing the left mouse button is changed to meet the user's requirements. For the rest, such as the right mouse button, the mouse wheel, or the mouse movement sensor, the initial setting parameters are retained. According to the invention, the setting command is not limited in content.

[0031] In summary, according to the invention, the control unit 12 of the input device is used to analyze the input / operation signal. Based on the analysis result, it is determined whether a setting command is generated. The setting command switches the input device from the currently used first operating mode to a second operating mode. The design described above can improve the convenience of operating the input device, effectively avoiding problems associated with inconvenient mouse operation due to age or application program limitations.

[0032] The following refers to Fig. 3 Reference is made. The mouse 1a in Fig. 3 differs from the mouse 1 in Fig. 2 in that the mouse 1a further comprises a display unit 18 connected to the control unit 12. When the control unit 12 generates the setting command, a display signal is displayed by the display unit 18.

[0033] In practice, the display unit 18 is designed, for example, as an LCD screen 8, light-emitting diode LED or light assembly.

[0034] When the operating mode is set by the mouse 1a, a display signal such as trophies, treasures, scrolling texts, texts, or patterns is displayed on the display unit 18 of the mouse 1a to make the mouse 1a interesting. Furthermore, the mouse 1a can download the trophies, treasures, scrolling texts, texts, or patterns through the website authentication methods. The display signal is displayed on the display unit 18 of the mouse 1a. According to the invention, the embodiment of the display unit 18 is not limited.

[0035] In addition, the mouse 1a has a sound unit 20 connected to the control unit 12. The control unit 12 generates a setting command, with which the sound unit 20 outputs a sound signal. In practice, the sound unit 20 is, for example, a loudspeaker or a microphone. If the operating mode is set by the mouse 1a, the mouse 1a can output a sound signal via the sound unit 20, such as a cheering sound, a song, or a compliment, to amuse the mouse 1a. According to the invention, the embodiment of the sound unit 20 is not limited.

[0036] It should be noted that in other embodiments, the input device is a transparent keyboard or a transparent mouse. When the operating mode of the input device is set, the input device is displayed in different colors by the display unit 18, which may be embodied as a light-emitting diode, for example. For example, the transparent keyboard or the transparent mouse can emit a red, green, or blue light, with the green light representing the first operating mode, the blue light representing the second operating mode, and the red light representing the third operating mode. According to the invention, the embodiment of the input device is not limited.

[0037] From the above-mentioned embodiments, a method for responding to the operating state of an input device can be summarized. As shown in Fig. As shown in Figure 4, the method according to the invention for responding to the operating state of an input device comprises the following steps: Step S401: Generating an input / operation signal by operating a left mouse button, a right mouse button, a mouse wheel, a mouse movement sensor, or the combination of these elements when a user operates a mouse; Step S403: Using the input / operation signal, the input device sends an input / operation command to a computer. As an example, the mouse pointer is positioned over the desktop window and the user presses the right mouse button, which displays a menu with an input / operation command to be sent to the computer. Alternatively, the mouse pointer is positioned over the desktop window and the user presses the left mouse button, which displays a box for confirming the input / operation command to be sent to the computer. This is known per se and therefore requires no further explanation.

[0038] Step S405: Analyze the input / operation command. In practice, when a user operates the mouse in such a way that its input unit is pressed very frequently, the input / operation signal is inputted correspondingly frequently. This means that the time interval between any two input / operation signals is shortened. Thus, the control unit analyzes the input / operation signals to increase the transmission frequency to meet user requirements.

[0039] However, if the mouse's input unit is not pressed frequently, the time interval between any two input / actuation signals increases. The control unit then analyzes the input / actuation signals to reduce the transmission frequency to meet user requirements.

[0040] Step S407: Generate an adjustment command based on the analysis result. Specifically, the control unit analyzes the input / operation signals. If the time interval between any two input / operation signals shortens, the control unit generates an adjustment command based on the analysis result to increase the transmission frequency to meet user requirements.

[0041] Otherwise, the control unit analyzes the input / operation signals. If the time interval between any two input / operation signals increases, the control unit generates an adjustment command based on the analysis result to reduce the transmission frequency to meet user requirements. According to the invention, the content of the adjustment command is not restricted.

[0042] Step S409: Transferring the input device from a currently used first operating mode to a second operating mode. In practice, the control unit generates the setting command that changes the mouse's operating mode. Of course, all parameters related to the mouse's operating mode are changed according to the analysis result.

[0043] For example, the first transmission frequency in the first operating mode is 125 Hz. This means the mouse sends an input / operation command to the computer every 8 microseconds. If the user frequently operates the mouse, the control unit analyzes the input / operation signals and generates a setting command based on the analysis results, which switches the first operating mode to the second operating mode. The second transmission frequency of the second operating mode is 250 Hz. This means the mouse sends an input / operation command to the computer every 4 microseconds. This increases the transmission frequency to meet user requirements.

[0044] In Fig. Figure 5 shows a flowchart of another method according to the invention for responding to the operating state of an input device. The method is similar to that in Fig. 4. For example, a setting command can be generated based on the analysis result, by which the input device is transferred from a currently used first operating mode to a second operating mode.

[0045] However, there are still differences between the procedure according to Fig. 4 and the procedure according to Fig. 5. According to Fig. 5, the procedure comprises the following steps: Step S501: Generate an input / operation signal. When a user operates the mouse, it generates an input / operation signal.

[0046] Step S503: Using the input / operation signal, cause the input device to output an input / operation command to a computer.

[0047] Step S505: Determine whether the cumulative number of input / operation signals reaches at least a preset number in a storage unit. If so, the control unit analyzes the cumulative input / operation signals [step S507].

[0048] Specifically, one or more predefined numbers of times are stored in the memory unit. The predefined number is the cumulative number of times the user has operated the mouse or the mouse's input unit has been pressed. For example, the predefined number of times can be 10,000. If the mouse is operated up to 10,000 times, the control unit can analyze the cumulative input / operation signals. The cumulative input / operation signals contain information about the trigger click time / frequency. This is how the control unit analyzes the cumulative input / operation signals.

[0049] It should be noted that the analysis of the input / operation signal performed by the control unit in step S507 may involve determining whether the number of times the input / operation signal is received within a predetermined period of time reaches the predetermined number. If so, the control unit generates the setting command to transfer the input device to the second operating mode. If not, the control unit outputs the input / operation command to the computer. However, there are no restrictions on how the control unit analyzes the input / operation signals within the predetermined period of time.

[0050] Step S509: Generation of a setting command by the control unit.

[0051] Step S511: Transfer the input device from the currently used first operating mode to the second operating mode. Anything beyond the above description is known per se and needs no further explanation here.

[0052] In Fig. Figure 6 shows a flowchart of yet another method for responding to the operating state of an input device. The method is similar to that in the aforementioned embodiments. For example, a setting command can be generated based on the analysis result, which converts the input device from a currently used first operating mode to a second operating mode.

[0053] However, there are still differences between them. According to Fig. 6, the procedure comprises the following steps: Step S601: Generate an input / operation signal. When a user operates the mouse, it generates an input / operation signal.

[0054] Step S603: Using the input / operation signal, cause the input device to output an input / operation command to a computer.

[0055] Step S605: Determine whether the input / operation signal is a trigger signal. If so, the subsequent input / operation signals are analyzed within a specified period of time after the control unit is triggered. This represents step S607.

[0056] More specifically, the input device has an actuation mechanism for triggering signals. For example, if the right mouse button is held down for up to 5 seconds, the input device determines that the input / actuation signal is a trigger signal. In other embodiments, the trigger signal can be activated by pressing a setting button (not shown in detail) or by simultaneously pressing the right and left mouse buttons. In this embodiment, the actuation mechanism for triggering signals is not limited.

[0057] Then, subsequent input / operation signals are analyzed within a specified period of time after the control unit is triggered. In practice, if the user operates the mouse to play computer games within ten minutes, the mouse analyzes the input / operation signals input within ten minutes of the control unit being triggered. If the mouse is operated at a high click speed, the control unit can analyze subsequent input / operation signals to adjust the mouse to an operating mode adapted to the computer games.

[0058] Step S609: Generation of a setting command by the control unit.

[0059] Step S611: Transfer the input device from the currently used first operating mode to the second operating mode. Anything beyond the above description is known per se and needs no further explanation here.

[0060] In summary, the input device's control unit is used to analyze the input / operation signals. Based on the analysis results, it is determined whether a setting command is generated. The setting command switches the input device from a currently used first operating mode to a second operating mode. This measure ensures increased usability of the input device. Furthermore, problems associated with inconvenient operation of the input device, which can be caused by human or application program constraints, can be effectively avoided.
