Description

Pointing apparatus for computer comprising touch pad}

The present invention relates to a pointing device for a computer using a touch pad, and more particularly, to a touch pad unit for receiving an input for controlling a position of a pointer on a screen, and a predetermined function in a pointing mode performed by the touch pad. The invention is characterized in that the function button unit used in the pointing device for a computer having a function button unit for receiving a command.

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 the pointer that specifies the content and location of the executable command.

Since then, as computers have become smaller and more portable, touch pad pointing devices have been developed and used as integral parts of the computer to replace a mouse connected to the outside of the computer for added convenience.

1 is a view showing a general notebook computer having a touch pad as a pointing device.

The pointing device includes a touch pad 110, a first function button 120, a scroll wheel 140, and a second function button 130.

The first function button plays the command selection / execution function to the right-handed user, and selects and executes the pointer on the monitor menu. The second function button plays the menu expansion function. , The menu will be revealed.

The scroll wheel is responsible for quickly moving the contents of the screen up and down to navigate the contents of the monitor more efficiently.

On the other hand, the first function button and the second function button may be applied through the program as opposed to the right-handed function of the function button to provide the same convenience to the left-handed.

As shown in FIG. 1, a pointing device such as a mouse, a touch pad, and a pointing stick is provided with a part for controlling a position of a pointer and a button for additional function command to input an accompanying execution command.

On the other hand, the mouse moves the mouse itself to set the position of the pointer, but in the case of a touch pad or pointing stick integrated with a keyboard, the position of the device is fixed, and instead, the position of the pointer is set by moving a finger.

However, moving the finger on a fixed device to determine the position of the pointer and pressing various function buttons has the disadvantage of moving the device itself like a mouse and pressing the function button while the hand is fixed on the pointing device. .

That is, in the case of a mouse, the touch pad is convenient because the operation required to set the position of the pointer and the operation of the command button for executing the command are terminated by pressing the finger in a stopped state after the movement of the mouse. B. Pointing stick needs to be moved additionally after setting point position, which may cause inconvenience compared to mouse in continuity and promptness of input action, or index finger should move while thumb is fixed on function button. The force will enter the discomfort.

For example, a mouse can perform various commands by using the thumb, the index finger, and the middle finger without additional movement of the hand or finger at the same time as selecting the position coordinates, whereas the touchpad device may use an unnatural or additional wrist to operate the command button. In this case, the input of the execution command is completed only when both hands are used.

For this reason, even though these pointer input devices exist in the main body of the notebook, a separate mouse is connected and used.

There have been many studies to improve such inconvenience in use, an example of this effort is shown in Korean Patent No. 10-0259264 (registration number), the structure 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 Registration Application No. 1997-003481, the fingers other than the thumb are placed on the keyboard to reduce the movement of the hand to operate the touch pad. Two command buttons were placed on the left side of the touchpad located below the space bar of the keyboard so as to operate (Fig. 3).

In another Korean Patent Application No. 2000-0013510, a method of reducing the movement of a hand or a space occupied by a mouse or a touch pad by allowing a key of a keyboard to function as a touch pad. Also presented.

In addition, Japanese Patent Application No. 2000-213492 arranges the touch pad 410, the execution button 420, and the scroll button 430 as shown in FIG. 4 to move the pointer with the thumb, and then additionally moves the accompanying command. We devised a form that can be executed by operating the click button without detecting and stopping.

However, the above studies only suggest the position of the function button or the like and the addition of a new additional function to the touch pad, and the function button itself has not been studied yet.

That is, one of the reasons that the touch pad as a pointing device causes inconvenience in use compared to the mouse is that the mouse during operations such as drag (controlling the change of the position of the pointer while pressing a function button) Simply press the function button and move the hand itself without moving the finger.However, in the case of the touchpad, keep pressing the function button and keep moving the finger to control the position of the pointer. It is not easy to maintain, and there is no research on this.

In order to solve the above problems, the present invention provides a pointing device for a computer using a touch pad having a function button which is easier to press, and has a convenient function of controlling a position using the touch pad in a pressed state, and a screen control method using the same. .

In order to achieve the above object, the present invention provides a touch pad unit for receiving an input for controlling a position of a pointer on a screen, and a function button unit for receiving a command of a predetermined function in a pointing mode performed by the touch pad. In the pointing device for a computer using a touch pad provided, when the function button unit is in a state that the function button unit is pressed, the height of the surface of the function button unit is characterized in that the height of the circumferential surface of the function button unit or more Provided is a pointing device for a computer using a pad.

It is preferable to include.

Here, the function button is provided with a guide groove that can be inserted into the projection on the lower surface, the function button portion is provided on the side of the switch, when the function button is pressed to protrude from the bottom surface of the function button portion It may be configured to further include; guide projections formed to be inserted into the guide grooves

The function button may be provided in the form of a lever. A pointing device for a computer using a touch pad having a touch pad unit for receiving an input for controlling a position of a pointer on a screen, and a function button unit for receiving a command of a predetermined function in a pointing mode performed by the touch pad. In the above, the function button unit provides a pointing device for a computer using a touch pad, characterized in that it comprises a switch that is turned on by the contact of the human body.

Here, the switch that is turned on by the contact of the human body in the function button unit is preferably a touch pad.

Meanwhile, in order to achieve the above object, the present invention provides a touch pad unit for receiving an input for controlling a position of a pointer on a screen, and a function for receiving a command of a predetermined function in a pointing mode performed by the touch pad. In the screen control method using a pointing device for a computer using a touch pad, characterized in that provided with a button unit, the function button unit is provided with a switch that is turned on by the contact of the human body, Determining if there is contact; Classifying a type of command input to the function button unit by using the contact time, the time during contact, the time during which no contact is made, and the number of touches; And performing a corresponding function according to the type of the distinguished command. The screen control method using the pointing device for a computer using the touch pad is provided.

On the other hand, in order to achieve the above object, the present invention provides a computer readable recording medium having recorded thereon a program for realizing the above method.

According to the present invention, it is easier to press a function button provided in the touch pad, and in particular, it is more convenient to control the position of the pointer using the touch pad while pressing the function button.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, in the pointing device with a touch pad according to the present invention, a case in which a button operates in a push switch method will be described as an example.

One of the primary features of the present invention is that when the function button is pressed the height of the surface is set to be at least the height around the function button, ie at least the same height as the circumferential surface.

A description with reference to FIG. 5 is as follows.

5 is a cross-sectional view of the touch pad 502 and the function button 501 taken along the line A-A 'in FIGS. 5b to b "and 5c to c" according to the position of finger pressing.

5A of FIG. 5 illustrates an example of a pointing device having a touch pad, and for convenience of description, there is one function button 501 in addition to the touch pad 502.

FIG. 5B (5b 'and 5b') is a sectional view based on AA 'in FIG. 5A and shows an example in which the concept of a conventional function button is introduced, and FIG. 5C (5c' and 5c '). Illustrates the features of the present invention.

 5b and 5c show that the function button is off before the finger presses the edge of the function button away from the touchpad. 5b shows a case where the function button surface touched by the finger is the same as the surrounding height, and 5c shows a case where the finger is higher than the surroundings in the off state.

5b 'and 5c' represent the position of the finger (thumb) when pressed and turned on, respectively, and 5b '' and 5c '' are off and on respectively when the finger presses the edge of the function button close to the touchpad. Is showing.

As shown in FIG. 5, the disadvantage of the touchpad used as a conventional pointing device is that the function button contact surface where the finger touches is the same height as the surrounding surface as shown in FIGS. In the case of the finger movements naturally, but in order to maintain the on state, the function button is recessed from the surrounding surface, so only the center part should be pressed, and when the edge is pressed, the pressing operation is disturbed by the peripheral surface of the function button. The finger must be at the center of the function button for smooth pressing.

 In particular, in order to press the center of the function button, the finger should not lie in parallel with the surrounding surface, but tilted to some extent, and only the fingertips should be used for smooth pressing.

 On the other hand, the structure of the function button provided in the present invention shown in Figure 5c ~ c '' in the off (off) function button protrudes compared to the peripheral surface but in the pressed state to have the same height as the peripheral surface or higher than the peripheral surface Therefore, it is not necessary to press the finger upright, so that the movement of the finger is free, and even if the finger presses only the peripheral surface where the finger is in contact with the function button, it acts as a reference surface to keep the pressing state using the surrounding surface. It is possible to maintain the on state.

Therefore, the finger pressing the function button does not need to apply the maximum force to maintain the on state of the function button, but only to maintain the minimum force enough to check the peripheral surface contact with the function button, or the weight of the hand by gravity You can stay on alone.

And another advantage of the function button provided by the present invention as shown in Figure 5c is that the finger (mainly thumb) for operating the function button can be operated even while lying parallel to the peripheral surface. This determines the magnitude of the force applied to the finger because the palm must be away from the periphery in order to have the shape of the thumb shown in Figure 5b. The focus is on the finger (finger) and the finger (thumb) operating the function button.

However, the shape of the finger shown in Figure 5c is because the palm can touch the surrounding surface, so the force supporting the hand is concentrated on the palm and relatively small force is applied to the finger, and this small force reduces the elastic force of the spring of the function button. This is because there is no problem, so as a result, it is easy to press the finger operating the function button.

Furthermore, when the function button is on and has the same height as the circumferential surface, even when the function button is on, the finger may move further upward above the touch pad as shown in FIG. 5C '', and as a result, the movement of the finger operating the function button operates the touch pad. It is possible to move up, down, left and right in parallel with the surrounding surface freely like a finger. This is the description of the function button to be provided by the present invention.

6 and 7 illustrate the convenience caused by the change of the width of the function button ('C' in FIGS. 6 and 7). If the width is less than 5mm (Fig. 6) and more than 10mm (Fig. 7), if the width is small (Fig. 6), the two peripheral edges where the finger touches the up and down of the function button are always detected and are relatively small. In the case of a large width (FIG. 7), only one of the edges of the peripheral surface which is in contact with the function button should be kept pressed and must be pressed with a relatively large force. However, the greater the width of the function button, the greater the movement of the finger to operate the function button, bringing convenience in operation.

FIG. 9 is a cross-sectional view illustrating another example of a pointing device for a computer having a touch pad, taken along a line BB ′ of the function button 702 of the touch pad shown in FIG. 8. It is.

FIG. 9 illustrates a structure using a dome switch 703 and a spring 704 that enable on / off of pressing any of the function buttons 702. Shows when the function button 702 of the touch pad 702 is in the off state 9a and in the on state 9b, c, d, and the position of the finger is on the left (9b), right (9d) and the middle thereof. When the center (9c) of the position of the function button is pressed, the height of the function button is changed.

9, the function button part of the touch pad illustrated in FIG. 9 includes a function button 702, a switch 703, and an elastic body 704.

Specifically, the function button 702 is configured to protrude beyond the peripheral surface 705 of the function button portion on the outer surface of the function button portion so that the user can press. In addition, the function button 702 is formed so as not to descend below the peripheral surface 705 even when pressed as described above.

The elastic body 704 is provided between the function button 702 and the bottom surface 706 of the function button unit to support the function button 702 and to restore it when the function button 702 is pressed. A representative example that can be used as the elastic body 704 is a spring, and if there is an article that can restore the function button pressed up again because of the elasticity is not limited in its kind.

The switch 703 comes in contact with the function button 702 when the function button 702 is pressed for a predetermined depth or more and is turned on by the function button 702, and the function button 702 is applied to the elasticity of the elastic body 704. In this case, it is provided on the bottom 706 of the function button unit so as to be turned off when it is restored to the original position.

On the other hand, when the function button unit is configured in the form as shown in Figure 9 has some disadvantages.

The height at which the switch is turned on depends on the position on the function button of the finger pressing the function button 702 to operate the switch 703. That is, when pressing the left and right ends of the function button 702 rather than the center of the function button 702, the on state is maintained by pressing deeper than when pressing the center.

Accordingly, unlike FIG. 5C, in the case of FIG. 9, when the height of the finger pressing the function button is fixed, the ON state cannot be maintained when the function button is moved over the function button.

For example, when the finger moves from the position of 9c to the position of 9d, the height of the function button is considered to be the same, and in this case, the state is changed from the on state to the off state so that the user's work must be repeated again.

That is, in the case of 5c of FIG. 5, FIG. 5c only needs to touch the reference plane (peripheral surface), but in FIG. 9, it should not be touched and should always be depressed, thus showing the difficulty of operation. .

In order to alleviate this disadvantage, there is a method of providing a guide groove in the lower portion of the function button 702 and a guide protrusion in the bottom 706 of the function button part.

FIG. 10 is a view illustrating a function button unit having a guide groove 707 below the function button 702, and a guide protrusion 708 provided on the bottom 706 of the function button unit.

As illustrated in FIG. 10, two guide grooves 707 and guide protrusions 708 may exist, or only one guide groove 707 may exist. In some cases, three or more guide grooves may be provided.

In addition, when there are a plurality of guide grooves 707 and guide protrusions 708, the guide grooves 707 and the guide protrusions 708 may be arranged in the longitudinal direction as shown in FIG. 10, or arranged in the width direction. It may be arranged, and may be arranged in a form surrounding the switch 703.

Since the guide groove 707 and the guide protrusion 708 are set to engage each other, the guide protrusion 708 enters along the guide groove 707 when the function button 702 is pressed. Therefore, even when the end of the function button 702 is pressed, the function button 703 is pressed while keeping the hand piece, and eventually the height at which the switch 703 is kept on is kept constant no matter where it is pressed.

In the above, the case where the function button is pressed to maintain the on state has been discussed with respect to the case where the function button is in contact with the same height as the surrounding surface, but even when the function button is actually higher than the surrounding surface in the on state, as shown in FIG. The principle of loom and operation is the same, so it does not matter.

In addition, as shown in FIG. 12, the surface where the finger of the function button touches may have a curved structure that is not flat. 12a in FIG. 12 is a case where the highest point of the function button is in the same position as the surrounding surface while 12b is in the on state. In this state, the highest point of the function button is in the position higher than the surrounding surface.

 Even when the function button in the on state is higher than the surrounding surface, the disadvantage of the function button shown in FIG. 9 (a difference in the height caused by the position of the finger on the function button occurs, and the function button is moved as the finger moves over the function button. If there is no movement in the height direction) and the height difference from the surrounding surface in the on state is not more than 10mm, preferably more than 5mm can be used equally.

FIG. 13 illustrates an example in which a function button is provided in the form of a lever as another embodiment of the present invention.

That is, the groove provided at one end of the function button 1302 is connected to the cylindrical shaft 1309 to allow rotation within the allowable angle of the function button unit, and the other end is restored by being supported by the elastic body 1304. Press and release of the function button can be performed.

Even in this case, the highest point of the function button 1302 is designed to be at a position equal to or higher than the peripheral surface when it is kept on.

In the case of the function button unit as shown in FIG. 13, the function button is fixed by the shaft 1309, so that the left and right ends of the function button are pressed while maintaining the same height as a whole, and therefore, even when the hand moves while pressing the function button 1302 on. The state can be prevented from being terminated.

As described above, if the entire surface of the function button is pressed while keeping the entire surface of the function button parallel to the floor, the height detected by the finger at the position where the finger on the current function button is placed is as described above. If you do not change even if you move over the function button itself will act as a reference plane to ease the movement of the finger.

In summary, when the height of the function button is the same as the circumferential surface contacting the function button, as shown in FIGS. 5C and 6, the circumferential surface acts as a reference plane, and the surface of the function button in the on state is maintained as shown in FIG. If it is higher than the surrounding surface, the finger touching surface of the function button acts as a reference surface while the function button is pressed, and the finger moves along this surface to keep it on.

Therefore, whether the reference plane is a flat surface, a curved surface, a fixed surface (peripheral surface) or an operating surface (upper surface of the function button), the finger operating the function button can be freely moved along this surface while maintaining the on state of the function button. It is the key.

Therefore, dragging or long sentence selection during the pointing operation of the touchpad requires holding the function button with the finger during the pointing operation. Therefore, both the finger pressing the function button and the finger that needs to move on the touchpad for pointing operation In this case, it causes fatigue, but under the function button structure of the present invention, such work is easily made, which brings convenience in use such as a mouse.

In addition, even when the function button has a lever shape as shown in FIG. 13, even when the surface of the function button touches the finger has an inclination with the surrounding surface (FIG. 13A), the same height is maintained when the function button is pressed (FIG. 13B). It can be used as the operation structure of the function button.

On the other hand, Figure 14 shows another example of the use of a switch that is turned on by the contact of the human body, rather than the push-type switch as a function of the present invention.

A representative example of a switch in which a function is turned on by contact of a human body is a touch pad using capacitance.

As shown in FIG. 14, two conventional capacitive touch pads used in FIG. 1 may be used so that one functions only a function of a function button.

If a plurality of function buttons are required, a plurality of touch pads may be provided for the function buttons. However, the touch pad 1402 for one function button is divided into the required number of function buttons, and the position touched by the user is determined. It may be performed in a manner of sensing and determining which function to perform.

In addition, the touch pad 1402 dedicated to the function button performs a function of the first function button (left function button in the case of a right-handed mouse), and the touch pad 1401 for pointer position control has a second function button (right-handle). In case of using mouse, the function of right function button) can be performed.

That is, since the second function button does not include a drag function, when the touch pad 1401 for the pointer position control tap is set, the second function button is set to recognize that the function of the second function button is to be performed. In addition, if only one touch pad is further provided, the functions of a general pointing device having two function buttons can be implemented.

In addition, when the touch pad 1402 dedicated to the function button is used in area division, the function buttons corresponding to the number of area division + 1 can be used.

14C of FIG. 14 illustrates an example of a method of classifying a type of a command input to the function button unit by using a time during contact, a time during which no contact is made, and the number of touches.

As shown in Fig. 14, when tapping once, it is a simple click. When tapping and touching again, it is held (tap and touch). In the case of one consecutive tap, it can be set to recognize by double clicking.

At this time, whether a simple click, it holds that the double-click recognize nine minutes important for one hour (t _on) and time (t _ff) does not touch contacts on the touch pad to the, the t _on and t _off time users can set up direct It is desirable to.

The implementation of the function button function by tapping can prevent the function button operation due to accidental contact, so even if a finger operating the touch pad is in contact with the touch pad 1402 for the function button, furthermore, dragging ( If the hold state of a function button for dragging is also implemented as a contact following tapping, this is also distinguished from accidental contact, maximizing user convenience.

In addition, the touch pad 1402 for the function button has one body, but the practical function brings the advantage that the expandability that can be divided into several parts is much improved than the mechanical push switch.

In addition, it is possible to eliminate the press (hold and hold) itself associated with the push switch can be eliminated a lot of tiredness of the thumb for pressing the function button when using the touch pad.

The implementation of the function button by the touch of the present invention may use a capacitive touch pad, but only another device may be used because only a human body may determine whether or not the body has been touched.

 Therefore, an optical sensor, a conductive film, a thin metal wire embedding, a pressure sensor, and a surface wave reflection method, which are used as a touch switch method in the touch screen, can all replace the function button of the present invention.

Various circuits may also be implemented, examples of which are illustrated in FIGS. 15 and 16.

15 shows a circuit diagram of an electronic touch switch using an IC (IC 4011). When a body is in contact with terminal A, an external circuit connected to the CD terminal is connected. When the terminal is in contact with terminal B, the external terminal is connected to a CD terminal. The circuit is disconnected and turned off.

To have the same operation mechanism as a normal function button, a metal plate is placed on the palm of the palm so that the B terminal is always in contact with a part of the body, and when the B terminal is connected to it, the function button switch is always in the off state and is turned on. In order to connect the A terminal with the function button 1402 shown in Fig. 14, a finger should touch it.

As shown in the circuit, even though the body contacts the AB terminal at the same time, the contact with the A terminal is dominant due to the difference in the resistances between the A and B terminals (A terminal-10 kΩ, B terminal-10 MΩ). If the body contact with the A terminal is lost while the contact with the B terminal is maintained, the circuit connected to the CD terminal is reduced to the OFF state.

FIG. 16 shows a circuit diagram of an electronic touch switch using transistors C9012 and C458. When a finger or a part of a body contacts the AB terminal at the same time, an external circuit connected to the CD terminal is turned on and a finger or a part of the body is touched. This break causes the external circuit to switch off. Therefore, the A terminal is connected to the function button (conductive plate in the strict sense) of FIG. 14, and the B terminal is connected to the conductor plate of the palm mounting surface where a part of the body is always in contact with the palm of the conductive plate when operating the touch pad. To make sure that the external circuit connected to the CD terminal is kept off.

17 is a block diagram functionally showing the configuration of the system of the present invention when using a touch pad, a touch switch, etc. as a function button unit.

As shown in FIG. 17, the apparatus of the present invention includes a contact determination unit 1701, a command separator 1702, and a controller 1703.

The function button function is assigned to the first touch pad 1401 for controlling the position of the pointer, and the touch pad 1402 for the function button is divided into a first area and a second area, and each function is different in each area. For example, if a button function is assigned, the function of each component is as follows.

The contact determining unit 1701 determines whether or not the human body contacts the touch pad. Specifically, the first touch pad 1401 has been touched or the second touch pad 1402 has been touched, and if there is a touch on the second touch pad, the first area has been touched or the second touched. Determine if there was contact in the area, and measure the time when the contact was made and when the contact was released.

The command classification unit 1702 classifies the type of command input to the function button unit by using the time during contact, the time during which no contact is made, and the number of times of contact, as determined by the contact determination unit 1701.

A specific example is shown in 14c of FIG. 14 and has already been described above, and further description thereof will be omitted. At this time, the threshold value of the time used as a reference for distinguishing each command in the command division unit 1702, that is, a time t _on contacted to distinguish each command and a time t _ff not contacted is determined by the user. It may be set in advance as described above.

The control unit 1703 controls the computer so that the commands of the function buttons divided by the command portion unit 1702 are executed.

18 is a flowchart illustrating a method of controlling a screen using a computer pointing device having a touch pad of the present invention when using a touch pad, a touch switch, or the like as a function button unit.

18 and 17, the function button function is assigned to the first touch pad 1401 for controlling the position of the pointer, and the touch pad 1402 dedicated to the function button is divided into a first area and a second area. And a case where different function button functions are assigned to each area.

First, the contact determining unit 1701 grasps a time and a number of times of contacting the human body to which part of the touch pad or the like is present (1801).

Next, the command classification unit 1702 is a type of the command input to the function button unit by using the time detected during the contact determination unit 1701, the time during which no contact is made, and the number of times of contact. (1802).

When the types of commands are divided in this way, the control unit 1703 controls the computer to execute the commands of the function buttons divided by the command part unit 1702 (1803).

The method of the present invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
