Description

Portable Digital Device having Graphic User Interface System which uses two cursors and two pointing devices as the input devices}

FIG. 1 is an example of a mobile phone (FIG. 1B) equipped with a touch phone 104 to replace a conventional mobile phone (FIG. 1A) and a keypad. FIG. 1 is a power switch and 102, 103, 105, and 106 are function buttons. The two-button mouse used in the execution button, menu expansion button and other functions of the mobile phone will be in charge.

FIG. 2 illustrates a case in which the mobile phone having the pointing device of FIG. 1B is gripped and operated with one hand (FIG. 2A) and with two hands (FIG. 2B). The screen is moved by moving a finger on the touch pad 203. The number is entered by placing the pointer on the number 4 of the virtual keypad 201 on the screen and pressing the play button 204.

3 illustrates a process for inputting '47' when the mobile phone having the pointing device as the input device of FIG. 1 (b) is operated with one hand. 3A illustrates a state where a pointer is positioned at the number '4' of the virtual keypad on the screen, and FIG. 3B illustrates a situation in which 4 is input on the screen by pressing the execution button 304. Figure 3c shows the process of moving the thumb down on the touchpad to move the pointer up the number '7' on the screen to enter additional '7' while already entering '4' and Figure 3d shows '7' The thumb moves from the touchpad to the play button and presses to execute a command to enter '.

Figure 4b shows the touch pad of the mobile phone at the same time the function of the function button to have the same operation principle as the mobile phone of the existing button arrangement, the movement of the finger is the same when the mobile phone operation. In other words, if the pointing device has the function of the function button, the input of 47 shown in FIG. 3 eliminates the need for FIGS. 3B and 3D, and the movement of the finger stops in FIGS. 3A and 3C and ends with a pressing operation. Accordingly, as shown in FIG. 4A, the user moves the finger on the touch pad to select '4' on the screen, followed by a pressing operation, and '4' is input, which has the same process as the input of the existing mobile phone shown in FIG. 4C. Subsequently, in the case of inputting '7', the movement and pressing operation of the finger for selecting '7' (FIG. 4B) is the same as in the case of the conventional mobile phone (FIG. 4D).

Figure 5 is a schematic structure of the touch pad for the operation of the function button 501 is a touch pad body, 502 is a button switch Figure 5a is a state before the touch pad body is pressed Figure 5b is a touch pad body is pressed It shows the state of time. 5C and 5D show a button switch located next to the touch pad main body so that the switch is operated in a lateral direction when the pointing device is pressed.

FIG. 6 shows a touch pad bundle having a function of a function button and a shape when the touch pad bundle is pressed to operate a button function (FIG. 6B). In the case of the general touch pad, the touch pad is operated by tapping the touch pad once with the finger. In this case, when the finger is released from the touch pad, an error occurs that the command to be executed cannot be executed. It is also possible that these additional fingers move up and down, requiring more energy and time than conventional keypad-type cell phones, thereby reducing the efficiency of number entry.

FIG. 7 illustrates that the resistance switch used for the touch screen is applied to the bottom surface of the touch pad 701. The upper conductor 703 and the lower conductor 704 are separated as elastic spacers 702 and the touch pad is pressed by a finger. When it comes in contact with the ground, and the pressure is removed, it is restored to its original state and serves as a switch function. In this case, the operation for operating the button switch of FIG. 5 can be reduced to one tenth of a millimeter.

FIG. 8 shows two types of Querty Phones. FIG. 8a shows a model LG9200 Qwerty Phone produced and sold by LG. The keyboard is provided in a slide form, and FIG. 8b is a Blackberry 8700 model.

9 illustrates a mobile phone using two touch pads 901L and 901R provided by the present invention. Each touchpad has four function buttons 902 to 905, which perform different functions when using a mobile phone, and the arrangement of these function buttons is sufficient to perform the functions of the pointing device with both hands or with one hand. To help.

FIG. 10 shows an example applied to a real mobile phone. FIG. 10C is a current SPH-B3100 model of Samsung Electronics, which uses a double hinge to enable horizontal and vertical viewing of a screen. Similarly, the arrangement of the pointing device of the present invention can be applied to both the case where the landscape view is advantageous, such as the e-mail or the multimedia player function, and the case of the portrait view for the phone function only, and the QWERTY phone having the function of the keyboard input device as shown in FIG. In view of the structure of the conventional QWERTY phone shown in Figure 8 as well as the built-in keyboard in a small space can be seen the advantages in that it can provide a graphical user interface (GUI).

11 is a view of using the mobile phone provided in the vertical view of the present invention can be used with one hand to enable a simple dialing by phone function and further provides a bar-type structure that enables the handset function.

12 is a view of the mobile phone provided by the present invention when using a landscape view, in which case both hands can be used to enable smooth operation of the character input and GUI system.

FIG. 13 shows that a telephone call can be made identical to a conventional mobile phone by using a GUI system in a portrait view mode. FIG. 13A is an initial screen displayed when the mobile phone is turned on, and the pointer (cursor) is positioned on the telephone call program icon, and then double-clicked (double-tap of the touch pad) to open the virtual keypad shown in FIG. 13B, and then 011-813- To dial 9715, move the cursor to the desired number from '0' to '5' (Fig. 13c) and press it in turn (press the touch pad) to enter the number on the screen. Move the cursor to the 'Call' button (press the touchpad) to make a call. To end the call, press the 'End' button. Unlike the existing mobile phone, you do not need to delete the wrong number even if you enter the wrong number, just select the wrong number and press the 'Cancel' button to delete and then enter a new number. This input method is the same as the method of modifying a character using a mouse in a computer. It is an advantage of the mobile phone provided by the present invention that the implementation of a function of the existing mobile phone is also possible through a program. Therefore, even if you are familiar with the call method using the keypad of the existing mobile phone provides an interface that can be used as it is. For example, even if only the last number 9715 is entered, the corresponding telephone number (011-813-9715) appears on the screen and the call button is pressed. In addition, if you press and hold '1' for a long time like the shortcut function of the existing mobile phone (if you press and hold the touch pad for a long time), you can connect to the phone number already entered.

Fig. 14 shows the use of an e-mail program as in the GUI system of an existing computer in a landscape view mode in a mobile phone having a pointing device provided by the present invention. Fig. 14a shows the main screen when the mobile phone is turned on. When the pointer (cursor) is placed on the e-mail program icon and double-clicked (the touch pad is pressed twice quickly), the e-mail program as shown in Fig. 14b opens and the pointer is again displayed. If you place it in the inbox and double-click it, you will see a list of outboxes as shown in Fig. 14C. Clicking on one of the e-mail lists opens the contents of the e-mail so that a new entry or modification can be made as shown in FIG. 14D. In this case, place the pointer where you want to enter the text to activate the text input mode, and then double-click to display the virtual keyboard at the bottom of the screen and place the part you want to enter text directly on the virtual keyboard. (FIG. 14E). And if you want to enter the body after the title input as shown in Figure 14f, place the pointer on the body and double-click the virtual keyboard automatically appears at the bottom of the screen and the body is located directly above the virtual keyboard, easy to check the characters when typing Done. When the text input is completed, move the pointer to 'Quit' and click (Fig. 14h) to exit the text input mode. At this time, press the upper button (903R) on the right touch pad to display the extended menu. Move to the 'Send' menu and click on it to send an email. Finally, clicking on the 'Exit' menu shown in FIG. 14i returns to the main screen.

FIG. 15 shows the virtual keyboard. FIG. 15A shows the virtual keyboard displayed on the screen when the text input mode is started. The left and right pointers are located at 'f' and 'j'. At this time, two pointers (cursors) appear on the left and right sides of the virtual keyboard, and each pointer does not cross the center line of the keyboard and operates only in the left region 1501 and the right region 1502 of the keyboard. It is designed to double the efficiency of text input by the left thumb and the right thumb in the same way as the keyboard. In other words, the two pointers do not intersect with each other, and no matter how the touchpad is operated, the pointers are fixed to the left and right sides so that the movement of two fingers (thumbs) is more free and the character input is the same as that of the QWERTY keyboard. It brings efficiency. In addition, the functions of 'Shift', 'Space bar' and 'Enter' which are frequently used in the character input mode as shown in FIG. 14g are handled by the function buttons around the touch pad to enable easy operation at a fixed position. It shows the increase in efficiency. In fact, pressing the 'shift' function button changes the keys of the virtual keyboard to the uppercase mode (Fig. 15b). Furthermore, when using these function buttons, the finger is released from the touch pad so that the user presses the function button and then returns to the touch pad. You will not be able to find the proper position of your thumb. To solve this problem, if you make a reference point (1503) by digging a protrusion or groove to a size that does not interfere with the movement of the thumb on the touch pad, after pressing the function button, the thumb is located at the reference point here again. Reference points-1503L and 1503R and the virtual keyboards 'f' and 'j' have reference points in absolute coordinates. Therefore, in the character input process, the position of the thumb in the touch pad is always detected from the reference point 1503 so that it is easy to grasp the movement of the thumb to find a key to be input next. Therefore, the character input method using the touch paddle according to the present invention also enables mechanical character input by finger position grasping like a keyboard.

16 illustrates an example of actually inputting a character using the reference points 1503L and 1503R on the touch pad. In the text input process, "... I am fine." To "... I am" are entered, followed by a space and then 'fine'. Fig. 16A shows a state in which 'am' is input and Fig. 16B shows a space function button pressed to input a space. Then, the virtual keyboard automatically moves the pointer to 'j' (Fig. 16C). Since the thumb on the left side has not moved, the left pointer remains at its original position 'a', and if only the right hand thumb is pressed back to the reference point 1503R after pressing the space function button, the position of the pointer and left and right thumb is always moved in association. Each key of the keyboard corresponds to a certain coordinate on the touch pad, and has the same effect as using a real keyboard.

FIG. 17 shows that a mobile phone having two touch pads and a plurality of function buttons provided by the present invention can be easily operated on a GUI system such as a mouse. FIG. 17A illustrates a method of selecting a document using a right touch pad and a left command execution button (a function button located below the left touch pad) during the process of deleting a document in the trash. FIG. 17B shows a right touch while pressing a command execution button. The process of moving a document to the trash using the pad. In the case of one pointer and two pointing devices, since the pointing devices operate independently, there is an advantage that the hand can be easily used as it is, thus ensuring convenience as a mouse.

FIG. 18 illustrates a mobile phone having a double sliding structure in which two touch pads are both capable of a horizontal view and a vertical view mode. Comparing the mobile phone of this structure with the mobile phone shown in FIG. 8A, the mobile phone provided in the present invention provides a space that can expand the screen as much as the keypad length of the body of the mobile phone of FIG. 8A so that the screen can be used more widely. If the size of the screen is the same, the size of the mobile phone can be as small as the keypad length of the body of the mobile phone of Figure 8a. Therefore, it is much more efficient in space than a QWERTY phone using a conventional keypad and more various functions are possible in terms of GUI implementation.

FIG. 19 lists electronic dictionaries having two touch pads (FIGS. 19B and 19C) and electronic dictionaries having conventional keypad input devices (FIG. 19A). In the case of an electronic dictionary having a touch pad provided by the present invention, a GUI system is provided. Because it operates on a basic basis, each built-in dictionary can be used in the same way as an application on a computer. When holding and using an electronic dictionary with both hands, use it as shown in FIG. 12A. 2B, the touch pad may be used with only one hand. The electronic dictionary provided by the present invention enables the use of multiple dictionaries at the same time as shown in FIG. In other words, if you click the radio button at the bottom of the screen that says "Work ...", you will be able to use the Japan-Korean dictionary in the same way as the English-Korean dictionary shown on the screen.

FIG. 20 shows an example of using a touch pad having a rectangular structure, unlike those shown in FIGS. 1 to 19, in a mobile phone and an electronic dictionary equipped with two touch pads provided by the present invention. The position and arrangement of the function buttons may be changed according to the change of the shape of the touch pad, and the number of function buttons may be changed in various ways.

FIG. 21 illustrates a structure for making text input using a virtual keyboard easier by making two or more reference points on a touch pad and associating these reference points with two or more keys of the virtual keyboard. There are four reference points (2101-L1, L2, L3, L4, R1, R2, R3, and R4) on the left and right touch pads, respectively.These reference points are s, e, f, c and j, i, l, m on the virtual keyboard. In this case, the characters inputted from the relative position from the reference point felt by the finger can be known without looking at the screen. For example, when the virtual keyboard starts, the pointer is automatically positioned at f and j of the virtual keyboard, and as shown in FIG. 21B, the finger on the touchpad is placed at the reference points 2101-L1 and R1 and starts to move the pointer. In this case, the finger on the left touchpad moves from 2101-L1 to L3, and the pointer moves from 'j' to 's' on the screen. If you press the touch pad in that state, 's' will be input. In other words, perception of relative position using the reference point makes it possible to determine the direction in which direction the finger should be moved as in the case of using the keyboard even when using the touchpad. You do not have to. As a result, even in the input method using the pointer, the absolute position like the keyboard can be set, and the virtual keyboard has the same convenience as the actual keyboard. The only difference is that the actual keyboard uses all five fingers while the virtual keyboard using the touchpad uses only one finger.

FIG. 22 illustrates a method of using a reference point on the touch pad when inputting letters or numbers in the portrait view mode. 22A illustrates an arrangement of reference points when the mobile phone is opened in the portrait view mode in the mobile phone structure using the double hinge shown in FIG. 10. That is, the reference point 2101-L1 is located above and 2101-R1 is located below. In portrait view, instead of the virtual keyboard, the keypad of the existing mobile phone is placed on the screen (virtual keypad) to enter letters or numbers. In this case, FIG. 22B illustrates the relationship between the virtual keypad and the reference point. If the virtual keypad appears on the screen at the start of portrait mode and is automatically programmed to place the pointer on the '5' as shown in Fig. 22A, the finger will span four reference points as shown in the circle on the right of Fig. 22B. Starting movement from the position provides the same ease as using the keypad of an existing mobile phone as shown in FIG. 21. 22C and 22D show the movement of a finger to input '8' and '0'. That is, from the position where the finger contains four reference points (pointer is above '5') to the position containing three reference points (pointer is the '8' position) and finally the reference point corresponding to 2101-R3 (the pointer is It shows moving to '0'). Therefore, it is shown that the input of letters and numbers can be easily developed in both the horizontal mode and the vertical mode using a plurality of reference points.

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 pads and pointing sticks have been developed and used as built-in pointing devices that can replace the mouse for added convenience. However, the difference between these devices and the mouse is that, unlike the mouse moving the mouse itself to set its position, these devices have a fixed position and instead operate the buttons that execute commands in the process of setting the pointer position by moving a finger. Additional movement is required, which makes it less convenient to use than a mouse. For this reason, even though these pointer input devices exist in the main body of the notebook, a separate mouse is connected and used. In particular, compared to these built-in pointing devices, the convenience of the mouse is that the operation required for positioning the pointer and the action of the command button for the execution command is performed by pressing the button while the finger is stopped after the movement of the mouse. It's about to end. On the other hand, the touchpad or pointing stick needs to additionally move the position of the finger in order to execute the execution command after setting the position of the point, thereby causing inconvenience in the continuity and speed of the input operation compared to the mouse. For example, a mouse can perform various execution commands by using the thumb, index finger, or middle finger without additional movement of the hand or finger at the same time as selecting the position coordinates, whereas a touchpad or pointing stick device may be unnatural to operate a command button. Additional wrist and finger movements are required, and in some cases, both hands must be used to complete execution command input. In order to improve such inconvenience in use and to facilitate the use of a mouse, a structure in which a function button is arranged above and below the pointing device has been devised. And a mobile phone with a pointing device according to the invention of the present invention is shown in Figure 1b. A method of using the same is shown in FIG. 2. In the case of using a mobile phone in this way, the use of a pointing device is as easy as using a mouse. In other words, using a pointing device such as a touchpad, move the index finger on the touchpad to move the pointer on the screen, and then use the thumb or stop to operate the function (play) button to execute the command while the finger operating the touchpad is fixed. This is done. This quick execution also provides the function of the function button to the pointing device to operate in the same way when the operation with one finger, which is usually the way using a mobile phone. For example, as shown in FIG. 3, the GUI system is configured to enter 4 on the screen, and then to enter a number of 7 to find 7 (FIG. 3C). ) To move to the function button 304 (FIG. 3D), and if a pointing device such as a touch pad has a function button function, the pointing operation of selecting 7 (FIG. 4B) is completed. Press the touchpad to enter 7. This shows that the finger of the existing mobile phone is moved from the button 4 (FIG. 4C) to the button 7 (FIG. 4D) and the input of the number 7 is completed by the pressing operation, thereby showing the coincidence of the operation. This is because the pointing device shown in FIG. 2B is operated by a plurality of fingers, so that the movement of the pointer and the execution of commands can be performed without changing the position of the finger, and also guarantee the same operation principle as the existing mobile phone even when operating with only one finger. do. That is, the same convenience as using a conventional mobile phone is guaranteed, and furthermore, since the function of a built-in mouse can be provided at the same time, a GUI system is provided to provide a mobile phone. Nevertheless, the text input using the pointing device is still relatively slow compared to the keyboard, and although the GUI system can be implemented in small digital electronic devices such as mobile phones, it cannot be applied to devices requiring text input because it cannot replace the keyboard. For this reason, the keypad provided in addition to the numeric keypad increases the size of the mobile phone, which may cause inconvenience to the user or even maintain the size. It was difficult to develop a small electronic device with a GUI system.

Thanks to advances in semiconductor technology, vacuum tube-based computers in the mid-20th century are now miniaturized and integrated so that they can fit in your hand. (laptop) Routines have already been made through computers and PDAs. Furthermore, devices such as mobile phones, MP3s, and PDPs, which were previously unrelated to computers, are in charge of additional functions such as computers, or are in the age of convergence where these functions are included in portable Palmtop computers. With this trend, it is time to introduce computer graphical user interface (GUI) systems to these small electronic devices. However, the pointing device, which is essential for a graphical user interface (GUI) system of a computer, has not been applied due to the space limitations and usage problems in which these small electronic devices can be mounted. In order for the pointing device to be applied to use a graphical user interface (GUI) system, the size of the touchpad or pointing stick already used in a laptop computer and the like and the structure and size of the function button used with the pointing device need to be changed. will be. Designed to overcome this point, touch screens and input pens are currently applied to palmtop computers or PDAs, but such touch screens or input pens cannot be applied to a size that needs to be operated with one hand such as a mobile phone. Accordingly, it is a technical problem of the present invention to provide a mobile phone using a pointing device that has the convenience of a mouse and may be operated by one finger in some cases.

The touchpad, pointing stick, and trackball, which are used as pointing devices, are devices for changing the position of the pointer. The principles for moving the pointer differ from each other, but they require additional operation of the function buttons to execute commands in the GUI system. . In fact, even when a group of sentences are selected and moved in word processing in a GUI system or when a file is selected and moved at the same time, the function button arrangement of the present invention is arranged as shown in FIG. 2B. The present invention provides a mobile phone having a true GUI system without an array of buttons so that it can be easily operated. The configuration of the present invention is accompanied by an arrangement of function buttons arranged up and down on a touch pad having the same ease of use as a mouse. The touchpad also functions as a function button for enabling finger operation. In particular, in the case of a touch pad for one-finger operation, a method of providing a function button is described with reference to FIG. 5. As shown in FIG. 5, when the touch pad is pressed by attaching a click switch to the bottom of the touch pad, the click switch is switched from off to on, and the pressed touch pad is returned to its original state. Since the click switch is switched from the on state to the off state, it is responsible for the function of the function button. Therefore, the pointing device of the present invention provides a pointing device that is also in charge of the function of a touch pad 501 and a function button for operating the click switch 502 when pressed to have a pivot structure. When using the pointing device including the function of such a function button has been described in Figure 4 the difference brought on the operation of the mobile phone. That is, in FIG. 3, since the touch pad does not have a function button, a finger movement from the touch pad to a function button is required to input the number 7, whereas the touch pad of FIG. 4 b has a function of a function button. By pressing the touch pad without this movement, the number '7' is entered. 4C and 4D show that the movement of the finger is the same when comparing this with the number input method of the conventional button-type cellular phone. In the case of a mobile phone using such a touch pad, there is an advantage in that a GUI system can be introduced, but there is still a limitation in the text input method, because two hands cannot be used as compared to a conventional keypad type mobile phone. In particular, compared to the QWERTY phone, the input method using the touchpad becomes slower and cannot be followed in terms of character input efficiency. In order to overcome this point, it is the configuration of the present invention to bring the same character input efficiency as the QWERTY phone by using two touchpads at the same time by using two touch pads. As well as increasing, pointer operation in a GUI system is much easier than with a single touchpad. As shown in FIG. 17, even in operations such as drag & drop, convenience of use is brought like a mouse. In addition, the present invention provides two touch pads and two pointers associated with the touch pads to achieve rapid character input. The reference point is formed on the touch pad to provide convenience in use as a keyboard, thereby implementing convenience of the keyboard.

The present invention applies two touch pads, which are built-in pointing devices that can replace the mouse of a computer, to a gripped small electronic device such as a mobile phone and a PDA, thereby maximizing character processing capabilities such as a computer and It brings the same functional convenience. Especially when it is held and operated with one hand, such as a mobile phone, it will be easier to convert an operating system that stays at DOS level to a Windows system when compared to a computer. And the advantage of the pointing device having the function of the function button to be provided by the present invention is that the input of the character brings the same input method as the existing keypad-type mobile phone when the user uses the mobile phone provided by the present invention It also brings another advantage that it is easy to use. Ultimately, the problem of keyboard processing, which is the most difficult in the process of miniaturizing computers and retaining computer functions of small digital electronic devices including mobile phones, will be solved, resulting in the rise of mobile phones or mobile phone-sized computers with computer functions. . In the case of conventional mobile phones up to now, all functions are operated by buttons, so when a pointing device such as the touch pad of the present invention is embedded in the mobile phone, the button on the front of the mobile phone is replaced by the pointing device. It will be arranged as a virtual button. Therefore, the number and size of the key buttons, which had to be limited due to the size of the mobile phone, could no longer be a limiting factor. For example, as shown in FIG. 8, a comparison is made between a Qwerty mobile phone that facilitates text input for expanding the text input function and a mobile phone having the pointing device of FIG. 10 designed according to the present invention. You can cut your phone size in half. Moreover, if you use the pointing device to input text on the screen, you do not have to worry about the stress of the finger that comes with operating the small keyboard key provided on the Qwerty mobile phone. Moreover, as shown in FIG. 17, the importance of the pointing device is shown in FIG. 17 that shows how ergonomically efficient the space is used, and further enables the application of a true GUI system. It is highlighted. Accordingly, the present invention enables the development of a Palmtop computer into a Fingertop computer. In this case, the mobile phone will no longer be a simple phone but will serve as a terminal of the information age, and the Internet, the basis of the information age, will face another era.
