Description

Ergonomically designed pointing device

1 illustrates a general notebook computer having a touchpad pointing device. The configuration of the pointing device includes a touchpad 110, a command selection / execution button 120, a scroll wheel 140, and a menu expansion button 130. . The command selection / execution button 110 is responsible for selecting and executing a menu for executing a command on the monitor, and the menu expansion button 130 is a command, information, menu hidden in a graphical user interface (GUI) system. It will be in charge of revealing functions. The scroll wheel is responsible for quickly moving the contents of the screen up and down to search the contents of the monitor more efficiently.

2 shows a notebook computer having a wired / wireless input device that is a removable touch pad and a mouse ball, which has a ball mouse on the bottom of the removable touch pad 210 of the figure, and then is detached from the main body and turned over to operate wirelessly. It is in charge of the function.

3 shows a notebook computer arranged with function buttons on the left side of the touchpad to act as the thumb of both hands.

4 shows a pointing device for operating the touchpad with the right hand. There is a command execution button and a menu expansion button 420 on the upper right side of the touch pad 410, and a scroll wheel 430 is arranged directly under the touch pad to move the pointer on the touch pad to move the pointer on the screen, and to execute commands and expand the menu. Detects and stops the device to operate the button 420.

FIG. 5 shows the structure of the pointing device of the present invention, in the case of a circular touch pad 5a and a typical rectangular touch pad 5b, in which a touch pad 510 is located at the center thereof, and command execution buttons and menu expansions are disposed above and below. When the buttons 520 and 530 are positioned and operated with the right hand, the thumb and the middle finger operate the buttons 520 and 530, respectively, and the index finger operates the touch pad 510. The actual hand is located in the pointing device of the present invention. Figure 5a and 5b are shown schematically in the figure.

FIG. 6 illustrates a case in which the scroll wheel 640 is added to the pointing device and positioned above and below the touch pad. The scroll wheel 640 is arranged between the command execution button and the menu expansion buttons 520 and 530 to be easily used.

FIG. 7 illustrates a structure of the pointing device that performs the same function as the pointing device of FIG. 6 by using the pointing stick 710 instead of the touch pad.

8 is a pointing stick 810 between the English keyboards G, H, and B in a manner that the pointing device is mounted in the keyboard so that the space bar and the English keyboards T, Y and U are in charge of the function of command execution button and menu extension button. The keyboard / pointing device shows the structure of the multifunction device, and the keyboards G and H (Scroll up) and B (Scroll down) are used to add the scrolling function to the pointing device of FIGS. 6 and 7. It is structure to have.

FIG. 9 shows an arrangement in which a conversion button 920 is disposed below a space bar for converting a function in the case of a keyboard / pointing device multifunction device so that character input and command execution can be simultaneously performed on the keyboard.

10 shows the position where the hand is placed on the keyboard / pointing device all-in-one (FIG. 9), where the position of the conversion button does not touch the conversion button when the finger presses the spacebar; It is an exemplary view showing that movement to a button is easy.

11 is a keyboard / pointing device all-in-one equipped with two pointing sticks in a keyboard to make the operation of the pointing device more efficient by setting the same position for operating the pointing stick and the position where the hand is placed when inputting characters; Indicates. In case of left-handed operation, the left pointing stick 1110 is operated and in the right-handed operation, the right-handed pointing stick 1120 is operated to perform a function as a pointing device (one-pointer two-pointing devices, one-two system). In the case of two-pointer systems with two pointers (two-pointers two-pointing devices, two-two systems), each pointerstick will control different pointers. In addition, the command bar functions as a space bar for left- and right-handed users, and the menu extension buttons function as keys R, T, Y, U, and I (or A, where the finger is placed, as in typing). , S, D, K, L, :) scroll wheel functions like the keys F, G, H, J (Scroll up) and V, B, N (Scroll down) have an array to handle The hand does not need to be released from the keyboard when the pointing device is activated. The button function of these keys is activated by pressing the conversion button 1130, and is pressed again to return to the original character input function. Furthermore, instead of having additional command execution buttons and menu expansion buttons normally associated with the pointing device, instead of giving the same button function to one of the left and right pointing devices, the pointing operation can be performed at the position where the hand is in a typing state. This enables pointing and text input to be performed simultaneously without shifting the position of the hand. For example, in the case of right-handed, the right pointing stick 1120 serves as an original pointing device, and the left pointing stick 1110 serves as a button function. If the pointing stick that is responsible for the button function is pressed down (key V direction for the left pointing stick, key N direction for the right pointing stick), the command execution function is up (key F, G direction for the left pointing stick), When the right pointing stick is pressed with the key H, J direction), it operates the menu expansion function or vice versa. In addition, if the user presses the pointing stick that functions as a function button twice and presses down or up, the function corresponds to double-clicking. The two pointing sticks have the same function as an external mouse. When the pointing stick is in charge of the button function as described above, the simple pointing operation can be easily performed without pressing the button by pressing the switch button. In addition, by pressing the conversion button 1130 in conjunction with the button function of the pointing stick, the pointing stick which is in charge of the button function can be returned to the original pointing function, and when the conversion button is pressed again, it can take the function of the function button. Two pointers capable of operating the controller and a pointing device for controlling each pointer are configured. The configuration of the pointing device in the keyboard and the corresponding function change have eliminated the need for hands to move between the pointing device and the keyboard so far, and thus the convenience and efficiency of the operation is much improved. It can be used by anyone without any modification or adjustment by software way. It also provides an ergonomic pointing device that can operate two pointers at the same time without hand movement, providing a true multi-pointer system. When the conversion button is operated, each key can be given a new function in addition to the original character input function, so that the function of the shortcut key necessary for the operation of the computer program can be performed, thereby increasing the efficiency of the computer.

12 shows various positions of the two pointing sticks. 12A shows that each pointing stick is located between the keys F, G, V and H, J, N and FIG. 12B shows that each pointing stick is located between the keys F, C, V and J, N, M. 12C is a case where each pointing stick is positioned between the keys D, F, and C 1210 and J, K, and M 1220. The pointing sticks in these positions allow the pointing stick to operate without involving hand movements when operated as an index finger. When both of these left and right pointing sticks serve as function buttons, the pointing device can be smoothly operated even in the character input mode of the keyboard. In addition, when the pointing operation is to be carried out continuously, the keyboard key acts as a function button using the conversion button 1230, and the pointing operation is performed with only one hand.

FIG. 13 additionally has conversion buttons 1330 and 1340 to activate only one of the two pointing sticks to prevent mixing of the pointing sticks 1310 and 1320. The operation of these toggle buttons switches to pointing device mode when pressed in keyboard mode and activates the functioning of the keys that work with the pointing stick and allows only the associated pointing stick to be activated. That is, when the conversion button 1230 is pressed in the keyboard mode, the pointing stick 1310 is deactivated, and the functions of the Y, U, I, H, J, B, N, space bar, and the pointing stick 1320 are activated. When the conversion button 1330 is pressed again, the keyboard mode is activated, and the pointing sticks are all deactivated to return to the original functions of the keyboard. The function of the conversion button 1340 is reversed. However, it is possible to change the function of these conversion buttons in various ways. In other words, installing two conversion buttons is a way to utilize the independent function of each pointing stick.

14 shows that the scroll wheel 1440 is located below the center of the touch pad, and the command execution button 1420 and the expansion button 1430 are located at the top of the touch pad 1410, but the command execution button is located at the center and the expansion button is command execution. It shows the pointing device that the thumb is in charge of the pointer movement and the index finger and the middle finger are located on the upper left and the upper right of the button. A pointing device that allows the button to be operated by simply pressing on the button without moving the finger.

FIG. 15 shows a hand placed on the pointing device of FIG. 14.

Figure 16 shows the shape of the hand and the position of the finger according to the position of the pointing device is different 16a is the position of the hand when using the touch pad of a typical notebook computer, 16b is the position of the hand when using an external mouse, 16c is a palmtop ( Palmtop) In handheld devices such as computers or PDAs, the hand and finger positions are shown when the pointing device is used.

17 shows how the hand grips the mouse when using the mouse. In general, the direction of the mouse also varies according to the position and direction of the hand release and the length of the hand coincides with the length of the mouse for ease of use. . This coincidence shows that the movement in the longitudinal direction or the perpendicular direction of the mouse is a natural gripping method to enable only the wrist joint movement, as shown in Figure 17a, b.

18 is different from that shown in FIG. 17 to move the pointer up and down and to the left and right on the computer screen when tilted from the length direction of the mouse and the length direction of the finger. It is accompanied by movement of up, down, left and right. Therefore, it is shown that the coincidence of the direction of the finger and the length of the mouse brings ergonomic convenience.

FIG. 19 illustrates that the circular touch pad does not coincide with the reference direction (circular longitudinal direction) of the touch pad and the length direction of the finger so that the finger and wrist joint movement is impossible to move the pointer on the screen. It shows that the movement of up and down, left and right should be accompanied. This is the same case as the case where the longitudinal direction of the mouse and the longitudinal direction of the finger shown in FIG. 18 do not coincide.

20 shows the movement of the hand (articulation of the finger and the wrist-indicated by an arc) due to the coincidence of the reference direction (rotating 45 degrees counterclockwise) with the finger direction of the circular touch pad.

FIG. 21 shows the reference movement of the circular touchpad, FIG. 21B shows a 45 degree counterclockwise rotation effect for the right hand grip, and FIG. 21C shows the vertical and horizontal programmatic views of the reference direction shown in FIG. 21B. Inter-conversions show that the program can be used by left-handers without the need for structural changes to the pointing device.

FIG. 22 shows the movement of the hand (linear movement of the wrist-indicated by a straight line) due to a mismatch between the reference direction and the finger direction of the rectangular touch pad.

FIG. 23 illustrates the movement of the hand due to coincidence of the finger touch with the reference direction (45 degrees counterclockwise rotation) of the rectangular touch pad.

24 is a diagram schematically showing the position and use of the hand according to the 45 degree change in the reference direction in the circular and rectangular touch pad pointing device.

The computer was converted into a graphical user interface (GUI) system since the advent of the mouse as a device that allows the computer monitor to move pointers that specify the content and location of executable commands. Since then, as the computer becomes smaller in size, the touch pad and pointing stick type pointing device have been developed and used as an integral part of the computer to replace the mouse connected to the outside of the computer for the convenience of use. It became. However, the difference between these devices and the mouse is that unlike the mouse that moves the mouse to set its position, these devices have a fixed position and instead move the finger to set the pointer's position. This makes these devices inferior to mice in terms of ease of use. For this reason, even though these pointer input devices exist in the main body of the notebook, a separate mouse is connected and used. That is, when the computer is operated as a GUI system, additional command buttons are essentially added to the mouse, touch pad, and pointing stick device in order to input additional execution commands in addition to the input coordinates. In particular, the ease of use of the mouse is that the touch pad is used for the operation required for positioning the pointer and the action of operating the command button for the execution command, which is terminated by pressing the finger with the finger stopped after the movement of the mouse. The pointing stick must additionally move the position of the finger after setting the position of the point, thereby causing inconvenience compared to the mouse in the continuity and speed of input. For example, a mouse can perform various commands by using the thumb, index finger, and middle finger without additional hand or finger movement while simultaneously selecting position coordinates. In this case, additional wrist and finger movements are required. In some cases, both hands must be used to complete execution command input. In order to improve such inconvenience in use, a lot of efforts have been made to improve the input structure of the touch pad or pointing stick device to complete the user's convenience such as a mouse. Ball mice have been developed to reduce movement, and the command buttons have moved from the first one to three, so that the position of these command buttons can be changed in various areas where they are detected, stopped, and perceived. An example of this effort is shown in Korean Patent No. 10-0259264 (registration number), which is shown in FIG. In this patent, the removable touch pad 210 was devised to overcome the inconvenience of the touch pad. An additional input device in the form of a ball mouse is formed on the opposite side of the touch pad, and when necessary, it is detached from the computer body and operated wirelessly. It can be used like a mouse. In addition, in the case of Korean Utility Model No. 1997-003481 (application number), in order to reduce the movement of the hand to operate the touchpad, the fingers other than the thumb are placed on the keyboard and the position coordinates are set and commanded by the touchpad using only the thumb of both hands. Two command buttons were placed to the left of the space bar of the keyboard so that the run button could be operated (FIG. 2). Another Korean Patent No. 10-2000-0013510 (application number) has a key on the keyboard to function as a touch pad to reduce the movement of the hand to use the mouse or touch pad, or to reduce the space occupied by the mouse or touch pad It also suggests ways to make this possible In addition, Japanese Patent No. 2000213492 (application number) arranges a touch pad 410, an execution button 420, and a scroll button 430 as shown in FIG. We devised a form that can be executed by operating the click button with the index finger and the middle finger without movement. Despite such a series of efforts, the pointing device currently provided integrally with a notebook generally has the form of a touch pad shown in FIG. 1 or a pointing stick at the center of the keyboard and an execution button located at the bottom of the space bar. . Accordingly, the present invention is intended to complete the convenience of use, such as a mouse by using a pointing pad mounted on a touch pad or a keyboard that is basically provided in a computer without additionally installing a mouse.

As mentioned above, the reason why the touch pad or the pointing stick as a pointing device is inconvenient to use compared to a mouse is because of the position where they are placed. For example, as shown in FIG. 16, in a computer system, the mouse is placed on the right or left side of the keyboard. The position of the finger on the mouse, in particular, the index finger and middle finger, which activates the function buttons of the mouse, are parallel to the length of the mouse. It is naturally placed on the button located at, so that no excessive force is applied to the detection and stopping when the button is operated. On the other hand, the touch pad provided in the form of a conventional computer is generally in the form of FIG. 1, wherein the touch pad is located at the center of the user and the hand is moved to the center of the user to operate the touch pad and the function buttons. When moving, the left and right button connecting direction and the hand and arm direction are inclined about 45 degrees (Fig. 16a). Unlike the mouse, two buttons are placed on the left and right sides of the index finger and middle finger or thumb and middle finger. The function buttons are disabled. In this type of touchpad, a finger can be placed either on the thumb, index finger, or middle finger on the touchpad to move the pointer on the computer monitor. If you use your thumb to lock the left and right buttons alternately, or use your right index finger to operate the touchpad and your left hand to activate the left and right function buttons. However, when the two command buttons 120 and 130 are used alternately, the movement of the finger becomes unnatural or causes interaction between the fingers, which causes errors in command execution, and when both hands are used, the pointing device can be operated with one hand. The work is less smooth than ever. In order to facilitate the movement of the finger, the present invention is that the design of the pointing device of the existing touch pad or pointing stick type is due to the left / right arrangement of the command execution / selection button 120 and the menu expansion button 130. In order to overcome this problem, the command execution / selection button and the menu expansion button were changed to be arranged up and down so that the position of the hand, especially the position of the finger, was matched with the arrangement of the function buttons. This arrangement of function buttons prevents the movement of the finger moving the pointer on the screen from intersecting with the movement of the finger that activates the command button. It is possible to achieve accurate and fast input such as using a mouse, and to achieve the same level of convenience. Therefore, the arrangement of the function buttons of the pointing device provided by the present invention is a device of a desktop computer, a notebook computer, a palmtop computer, a PDA, a videogame player controller, and the like to determine the position of the user's hand. By arranging the positions of the respective function buttons and the pointer input device of the pointing device at the position, the movement of the pointer and the execution of the command can be simultaneously performed while the hands are fixed.

In the configuration of the present invention, the structural contents are shown schematically from FIG. 5 to FIG. 24, and the contents thereof will be described in order. 5 shows a basic basis of the contents devised as a solution to the technical problem described in the present invention. When the touch pad is used as a structure of a pointing device of a computer, in particular, a notebook computer, the arrangement including a command execution button is a circular touch pad. A typical rectangular touchpad is shown in Figure B and the arrangement of the actual hand and finger positions is shown in the respective right figure.

The arrangement of the touch pad, the command execution button, and the menu extension button of the pointing device shown in FIG. 5 need not change the position of the input device according to whether the user is left or right handed, and the space required for the input device can be minimized. In the case of using a touchpad as a GUI (Graphic User Interface) pointing device of a general notebook, the position of the pointer is set on the monitor by the detection and the execution of the following commands is performed by operating the command button. Comparing the input device (FIG. 5) of the present invention with the existing pointing device (FIG. 1), the present invention has the following advantages. In other words, the pointing device (FIG. 5) of the present invention has the thumb and middle finger placed on the function buttons 520 and 530 when the index finger moves on the touch pad 510 to move the pointer. The support also enables fine adjustment of the pointer movement. In addition, the thumb or middle finger is a pivot that acts as a pivot while the index finger is fixed to the touch pad, helping the thumb and middle finger to move, and at the same time, the index finger is stopped on the touch pad to prevent the movement of the pointer. This has the advantage that command execution is executed in the correct location. Furthermore, the pointing device devised by the present invention is the same as the operation method of the mouse in that the function of the hand buttons and the movement of the fingers intersects with each other, as compared to the existing function buttons arranged side to side. . In particular, the pointing device using the touch pad shown in FIG. 4 also has the advantage that it can be operated like a mouse with one hand, whereas it is not a left-right symmetrical form, which has a disadvantage in that left-handed and right-handed people cannot share it. The device (Fig. 5) is symmetrical to the left and right, so that there is no space problem that must be arranged in a narrow space such as a notebook computer. 6 and 7 show a structure in which the scroll wheel is arranged in accordance with the purpose of the present invention together with a function button in the pointing device of the present invention in order to add a scroll function that is selectively mounted in the mouse. The scroll wheel is a device for increasing the efficiency of input by the touch pad or pointing stick to move the pointer on the screen, while the scroll wheel is responsible for moving the screen up and down. FIG. 6 illustrates a case in which the pointing device is a touch pad and FIG. 7 illustrates an arrangement of the scroll wheel in the case of a pointing stick. In each case, the scroll wheel is positioned above and below the touch pad or pointing stick. In FIG. 6B, when the scroll button is positioned above the touch pad, the function of the lower button may be executed simultaneously with the function of the scroll wheel 640. Functions, namely, command execution and selection functions, and the command button in the same direction as the scroll button are responsible for the expansion of the command, such as menu expansion, and the like is given a function that does not have to be performed simultaneously with the scroll button. In the case of the pointing stick illustrated in FIG. 7, the method of arranging the function buttons according to the arrangement of the scroll wheel 640 is the same as that of the touch pad illustrated in FIG. 6.

8 to 13 is a pointing device in the form of a pointing stick to provide a function of the function button to one key or several keys of the keyboard without installing a separate command button to maximize the space of the computer Device. This allows not only notebook computers but also desktop computers to function as pointer input devices by using a keyboard without a mouse. Specifically, Figure 8 is equipped with a pointing stick between the English keyboard G, H, B keys on the keyboard, the keys T, Y, U of the English keyboard, commands and menu expansion functions, the space bar is responsible for command execution and selection functions It also shows the basic structure to make the scroll function the English keyboards G and H (Scroll up) and B (Scroll down). In this case, it is not possible to perform the functions of the keyboard at the same time, so it is necessary to convert between the character input device function and the pointing function, and a layout diagram in which a conversion button 920 is added for this purpose is shown in FIG. 9 and FIG. Shows the hand position when using a device multifunction device. In particular, the position of the conversion button should not interfere with other functions and should be easily accessible and operated at the same time, so that the space under the space bar is easily accessible in any situation during the operation of the character input device or the pointing device. It is suitable for realizing the purpose of the device multifunction device. 11 shows that two pointing sticks are positioned in the keyboard so that the position of the hand for character input and the position of the hand when operating the pointing stick are maximized, thereby maximizing the efficiency of the computer input system. The only difference is that one or two conversion buttons are attached to reduce the confusion between the pointing stick and the keyboard. In order to increase the efficiency of the pointing device, when one of the two pointing sticks functions as a button even while operating in the character input mode of the keyboard, it is possible to easily perform computer operations without using a conversion button. In addition, there are many keyboard keys that are not yet in charge of the function, so that the computer can be applied as a shortcut with the necessary functions, and the use of this can greatly improve work efficiency. In the situation where two pointing sticks can be used while the wrist is fixed, a GUI having two pointers can be implemented by assigning a pointer (cursor) to each pointing stick one by one. In other words, if you are typing with one finger, known as eagle stroke, you can't use the two hands as if you are playing the guitar. Since it cannot be moved, it is impossible to take advantage of having two pointers, but as in the present invention, when the pointing device is operated using only the movement of a finger while the wrist is fixed, each pointer can be independently pointed. In effect, a real two-pointer system is implemented.

Finally, the pointing device shown in FIG. 14 differs from FIG. 5 in that the function buttons are not disposed above and below the touch pad, and are positioned only on the upper side. In fact, the pointing device of FIG. In the pointing device, the thumb actuates the touchpad and the index and stop actuate the function buttons. Nevertheless, even in the pointing device of FIG. 14, the command execution button and the expansion button located at the center are spaced up and down so that the detection and the stop are naturally placed. It is the same as the basic concept. In other words, the two function buttons have the same height and top and bottom and are arranged to the left and right, so that when the different fingers are placed on these buttons, the left and right buttons are spaced up and down to prevent the hand from coming into contact.

In the above, it is confirmed that the convenience of use in the pointing device is important to select the position of the function button, but there is one more point to consider in pursuing the convenience of use of the pointing device. This is due to the position of the hand, as shown in Figure 16, in the case of a device in which the pointing device is integrally used, since the hand is located in the center of the front of the body, the hand naturally has 45 degrees with the body. As a result, the length of the finger is 45 degrees to the body with the same reason, and if the wrist movement is not pursued by the present invention, the joint movement of the finger naturally forms the body to 45 degrees, but the finger is used to move the pointer. The movement of the up and down or left and right is ultimately accompanied by the movement of the wrist, not only the movement of the finger, which makes the use of the pointing device uncomfortable. In order to connect this natural finger joint movement and the pointer movement, the coordinates of the pointing device are inclined 45 degrees to the up and down direction of the computer device so that the main movement direction of the pointer coincides with the joint movement of the finger. It is another invention of the invention. 17 and 18 show the case of the mouse, when the longitudinal direction of the mouse coincides with the longitudinal direction of the hand (FIG. 17), the pointer can be moved up, down, left and right only by the joint movement of the wrist, but the length of the mouse is the length of the hand. If it does not match the direction (Fig. 18) it is shown schematically that the wrist must move up, down, left and right to move the pointer. When the pointing device is fixed, such as a touch pad, the reference direction of the coordinates of the fixed pointing device corresponds to the longitudinal direction of the mouse. In the case of a notebook using a touchpad as a pointing device, the vertical direction of the notebook, which is the reference direction of the coordinates, corresponds to the length of the mouse, as compared with the case of a mouse, and thus the direction of the hand using the touchpad is shown in FIG. 18. This is the same as when gripping in the inclined state of the mouse. Therefore, if the hand is inclined at 45 degrees to the reference direction of the touch pad, the wrist should move up and down rather than the joint movement of the finger in order to move the pointer. When tilted 45 degrees to the vertical direction of the hand is placed in the longitudinal direction of the hand (Figs. 20, 23) the vertical movement of the pointer on the screen, the left and right movement is made by the joint movement of the wrist and fingers, not the movement of the wrist in the vertical direction. As a result, the pointing work is carried out with the hands fixed, resulting in an ergonomic pointing device. The reference direction of the pointing device changes from a typical vertical form (FIG. 21A) to 45 degrees to the left and right (FIG. 21B, c), so that when the symmetry is applied to the left and right, the pointing device can be easily used. A simple application of the pointing device to the coordinate input signal conversion program enables the left-handed right-hander to use the device in common. The actual use of the circular and rectangular touch pad is shown in FIG. 24, the pointer can be easily moved only by the joint movement of the wrist and the finger without the movement of the wrist.

The present invention provides an input device that can replace the mouse of the computer by using a touch pad and a pointing stick structure, which is a pointing input device in the computer, in an ergonomically convenient manner, and to secure a space for use and use of the computer. The necessary devices are also simplified, and furthermore, GUI systems such as PDAs, Palmtop computers, and video game controllers can also be used as pointing devices to achieve the convenience and miniaturization of the external mouse simultaneously. Ultimately, even in the case of a desktop computer, it is possible to maximize the user's convenience by reducing the use space and the movement of the hand moving between the mouse and the keyboard by allowing the keyboard to point without the mouse. Using a single pointer in the system allows a two-pointer system implementation.
