Description

Terminal control method and pointing device {METHOD OF CONTROLLING TERMINAL DEVICE AND POINTING DEVICE}

The present invention relates to a terminal using touch recognition, and more particularly, to a pointing device and a method for controlling a terminal using a touch recognition device provided as a pointing device adjacent to a periphery thereof instead of a display.

In general, personal mobile terminals such as mobile phones and PDAs (Personal Digital Assistants) employ a user interface using a keypad. The conventional personal portable terminal has a keypad composed of a plurality of buttons for inputting numbers and characters, so that a user can input a telephone number or a character through a button of the keypad.

Recently, as the wireless Internet service is commercially available, a Windows operating system (eg, Windows CE) that supports a Graphical User Interface (GUI) has been adopted in personal mobile terminals. In addition, with the development of technology, the personal mobile terminal has various additional services, and an operating system supporting a GUI is also used for convenient operation of the various additional services.

As the operating system of the GUI is adopted as the user interface of the personal portable terminal as described above, other input devices such as an optical pointing device are adopted instead of the keypad which is disadvantageous to the operating system of the GUI. In general, the optical pointing device may be used similarly to a mouse of a PC by transferring image data of a surface of a subject (finger) obtained by irradiating light from a light source to an image sensor along a predetermined optical path.

Although there are optical pointing devices for changing the direction in personal handheld devices, these optical pointing devices need to have a minimum thickness and a length of a barrel to secure a path of light, so that the optical pointing device should be formed below a specific thickness and length. It is limited and the structure is quite complicated when adding a mechanism for detecting the press. In the optical pointing device, components such as a light source for irradiating light to a subject, an image sensor for analyzing light, and a prism for providing an optical path for guiding light reflected from the subject to the image sensor may also be used. It is a cause of increasing the thickness of the.

In addition, the conventional optical pointing device is capable of moving the pointer displayed on the display, but cannot provide various functions such as clicking or scrolling like other computer mice.

The present invention provides a pointing device which is disposed adjacent to a display of a terminal, but is provided in a substantially flat plane and occupies almost no mounting space, and a control method of a terminal including the pointing device.

The present invention provides a pointing device and a method for controlling a terminal based on touch recognition, which can easily maintain a structure of a direction electrode or a sensor, and can implement various functions in addition to simply detecting movement by touch recognition.

The present invention provides a pointing device and a method for controlling a terminal that can efficiently detect movement of a finger or the like in a small space within about 1 cm * 1 cm and can be easily applied to a button using a dome switch.

According to an exemplary embodiment of the present invention, a method of controlling a terminal in response to movement of an object on a pointing area includes providing a plurality of direction electrodes in the pointing area, and moving the object at a boundary of the pointing area. And performing another function distinguished from the direction detection in response to the detected signal.

The terminal of the present invention can perform other functions distinguished from the direction detection when the movement of the object is detected at the boundary of the pointing area. That is, in addition to the pointer movement by the signal sensed by the directional electrode, the object, for example, a finger enters from the outside of the pointing area, traverses or ends the pointing area, or pivots along the boundary of the pointing area. In response to the case, other functions that can be distinguished from the direction detection may be performed.

As described above, according to the present invention, in addition to detecting the direction by the direction electrode, other various functions may be performed according to whether the object is detected at the boundary of the pointing area, thereby increasing the utilization of the pointing device.

For reference, in the present invention, the boundary of the pointing region may include a periphery of the direction electrode disposed at the outermost of the plurality of direction electrodes. For example, the movement detection of the object at the boundary of the pointing area is made through a signal generated from the direction electrode as the object approaches the periphery of the direction electrode disposed at the outermost of the plurality of direction electrodes, or the plurality of direction electrodes. If the object directly overlaps the direction electrode disposed in the outermost of the can be made through a signal generated from the direction electrode. Alternatively, by defining a specific absolute coordinates including the periphery of the direction electrode disposed in the outermost of the plurality of direction electrodes, and comparing the contact coordinates and the absolute coordinates of the object to detect the movement of the object at the boundary of the pointing area. Can be.

In addition, the object is a physical body that can cause a change in electrical characteristics measured at the directional electrode, the body that can change the capacitance can be organic or inorganic. For example, it may mean a body part such as a finger, and a tool such as a stylus pen or a touch pen, or another material that can replace them.

In addition, the terminal refers to a device that can provide a pointing area for controlling the terminal function, and may also mean a device including a display in one device such as a mobile phone, a smart phone, a PDA, a notebook, or the like, and a remote controller. The main unit does not have a display, but it can also mean a remote control unit that can control other display units.

The directional electrode can generate an electric scalar (physical measurand) corresponding to the magnitude or change in electrical characteristics that are varied by the approach, retraction, and passage of the object. Can be measured. As the direction electrode, various sensing mechanisms may be applied according to required conditions and design specifications, and the present invention is not limited or limited by the sensing mechanism of the direction electrode.

In addition, the pointing area may mean a specific area in which the object is to be moved in the pointing device. Although the pointing area may be defined with a boundary in an appearance of a mobile terminal, the pointing area may be roughly positioned without a boundary. It may be displayed only as. The pointing area may be a separate area disposed adjacent to the display, but may be defined on all or part of the display.

On the other hand, it may include a ground electrode for preventing a change in the electrical characteristics generated during the detection of the finger on a particular direction electrode affects the connection line of the other direction electrode. Such ground electrodes may be provided in various structures depending on the required conditions and design specifications. For example, the ground electrode may be provided in a plane between each direction electrode. Alternatively, the ground electrode may be provided in the lower portion of each of the directional electrodes with a via hole through which the connecting line of each directional electrode passes, and the connecting line of each directional electrode may be disposed in the lower portion of the ground electrode through the via hole. have.

According to another preferred embodiment of the present invention, the pointing device for detecting the movement of the object on the pointing area includes a plurality of directional electrodes disposed in the pointing area, and the movement of the object is detected at the boundary of the pointing area. In response to the generated signal, other functions distinguished from the direction detection may be performed.

The pointing device of the present invention is disposed adjacent to the display of the terminal and performs a general direction detection function for moving a pointer or selecting a menu, and also scrolls and pages depending on whether a target object is detected at the boundary of the pointing area. Various functions such as flipping, screen switching, zooming in and out, and left and right clicks can be defined to be intuitively recognized, and the optimum function can be realized as a pointing device.

In addition, unlike the conventional optical pointing device, the pointing device is substantially provided in a substantially flat plane and occupies little mounting space, and has a merit that it takes up significantly less space than a function improvement effect.

In addition, according to the present invention, it is possible to prevent a change in electrical characteristics generated during the detection of a finger at a specific direction electrode by using a ground electrode affecting the connection line of another adjacent direction electrode, thereby preventing noise generation. It can prevent.

In addition, the present invention can efficiently detect the movement of the finger, etc. in a small space within about 1 cm * 1 cm, and is also integrally mounted in the button using the dome switch, and also combines the function of the pointing device to the existing button can do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. For reference, the same numbers in this description refer to substantially the same elements and can be described with reference to the contents described in the other drawings under these rules, and the contents which are judged to be obvious to the person skilled in the art or repeated can be omitted.

1 is a front view of a personal portable terminal to which a pointing device is applied according to an embodiment of the present invention, and FIGS. 2 to 5 are enlarged views for explaining a specific operation example of the pointing device of FIG. 1.

Referring to FIG. 1, the personal mobile terminal 100 according to the present exemplary embodiment may be provided with a display 110 at a front side thereof, and a pointing area 120 may be provided below the display 100. The display 110 may be capable of touch recognition by itself, but alternatively, the display 110 may be provided to enable only image display.

In the personal mobile terminal 100 according to the present exemplary embodiment, the user moves the pointer on the screen by moving his or her finger on the pointing area 120, moves a selected menu on the screen, or moves the finger on the screen. You can select and execute the desired function through the screen by matching it with movement.

A plurality of direction electrodes 130 arranged in a predetermined arrangement is provided on a bottom surface of the terminal case in which the pointing region 120 is formed. The direction electrode 130 may detect movement of a finger (or stylus pen) within the pointing area 120. When the movement of a finger is detected at the boundary of the pointing area 120, the direction electrode 130 may be generated. In response to the signal, another function distinct from the direction detection may be performed.

The arrangement and structure of the directional electrode 130 may be variously changed according to the required conditions and design specifications. Hereinafter, an example including a plurality of direction electrodes 130 arranged in a 3 * 3 grid will be described. For reference, the direction electrodes 130 arranged in a 3 * 3 can detect a change in capacitance according to a finger contact area, and although not clearly shown in the drawing, these direction electrodes 130 are controlled 1: 1 by the terminal. It is connected to the microchip of the chip or pointing device.

In addition, the direction electrodes 130 may be provided to have the same size and shape, and in some cases, the direction electrodes may be provided to have different sizes and shapes.

For reference, in the exemplary embodiment of the present invention, the direction electrodes 130 having a square shape are described as an example in which a 3 * 3 lattice is arranged. However, in some cases, the number of direction electrodes is further subdivided so that the finger is more precise. Movement can be detected, and the direction electrode can have a circular, non-circular, polygonal or other geometric shape. The shape of the directional electrode may also be variously changed to a circle, oval or polygonal shape according to the required conditions and design specifications.

Referring back to the drawings, the direction electrode 130 may be manufactured at a significantly lower cost than the conventional optical pointing device because of the simple electrode structure. In the present exemplary embodiment, the directional electrode 130 may be formed on the bottom of the case, but may alternatively be formed on the flexible circuit board, connected to the main circuit board of the terminal, and mounted in the case to be positioned below the pointing area. It may be. Of course, at this time, each of the directional electrodes may be formed on the same side or opposite sides of the flexible circuit board.

In addition, in some cases, the pointing area 120 may be provided in the form of a button, and the flexible circuit board on which the direction electrodes 130 are formed may be included inside or on the surface of the button. In this case, the user can move the finger on the upper surface or the exposed surface of the button and use it as a pointing device. Alternatively, the user can press a button to operate a dome switch or the like.

For reference, in the conventional optical pointing device, a pointing device including a lens, a barrel, a sensor, and the like must be moved as a whole to operate a button, but the pointing mechanism according to the present embodiment can be formed on an FPCB, and is also applied to a button. It is very easy to do.

Referring to FIG. 2, it may be assumed that a finger moves inward from the outside of the pointing area 120. The finger may approach four directions in the vertical direction or the left and right directions of the pointing area 120. In this case, after the movement of the finger is sensed at the boundary of the pointing area 120, the direction electrode 130 disposed inside the pointing area 120. ) Can occur for a certain period of time. In this case, the terminal may define functions other than general direction detection of the pointing device such as scrolling.

For reference, the boundary of the pointing region in the present specification may include a periphery of the direction electrode disposed at the outermost of the plurality of direction electrodes. In addition, in the present specification, "separate function distinguished from direction detection" may mean other functions previously promised in a terminal system or a specific program in addition to the direction detection generally expected in a pointing device, and may be described below. The screen can be selected in various ways such as screen switching, zooming in and out, and user-defined specific functions, user settings, and combinations of functions can be predefined. Hereinafter, a specific function will be described as an example in order to understand the function, but the specific motion of the finger and the corresponding function are not necessarily combined.

For example, when a signal is detected from the direction electrode 130 after the movement of the finger is sensed at the boundary of the pointing area 120 as described above, in response to the position of the boundary of the pointing area 120 at which the movement of the finger is detected You can select either up, down, left, or right scrolling. For example, when a finger passes through the upper boundary of the pointing area 120 and stops at the direction electrode 130, the terminal may cause the currently displayed screen to scroll down. In addition, when scrolling proceeds according to a setting, scrolling performed while a finger is kept in a touch state on the direction electrode 130 may be maintained. Of course, according to the position of the boundary of the point area where the movement of the finger is detected, it can be predefined to scroll down or to the left and right.

Of course, in the case where the finger moves inside the pointing area 120 and moves outside, a separate function corresponding thereto may be defined.

In addition, as shown in FIG. 2, when the scroll function is activated while the finger moves from the outside to the inside of the pointing area 120, the scroll mode may be continuously maintained, and the user's finger may be pointing to the pointing area 120. It is also possible to further control the scrolling direction when moving within.

Referring to FIG. 3, it may be assumed that a finger crosses or terminates the pointing area 120. In this case, after the movement of the finger is sensed on one side of the boundary of the pointing area 120, the movement is sensed through the direction electrode 130, and then the movement of the finger on the boundary of the opposite pointing area 120 can be detected. have. In this case, the terminal may also perform a separate function that can be intuitively understood, such as screen switching or page turning.

For example, as shown, after the movement of the finger is detected at the left boundary of the pointing area 120, a signal is detected from the directional electrode 130, and the movement of the finger at the right boundary of the opposite pointing area 120 is detected. It can be detected in turn. In this case, the terminal may perform a selected function among screen switching and page turning of the currently activated screen or text. Of course, in the opposite case, screen switching or page turning in the opposite direction may be defined.

In addition, as described above, it may be assumed that a finger passes in an inclined direction or a diagonal direction, and in this case, left and right clicks, enlarges and contracts according to the position of the boundary of the pointing area 120 through which the finger passes. You can define various functions such as undo and cancel.

Referring to FIG. 4, it may be assumed that a finger rotates along a boundary of the pointing area 120. That is, when the finger pivots along the boundary of the pointing area 120, the movement of the finger along the boundary of the pointing area 120 may be detected at the boundary of the pointing area 120, and in this case, various functions may be executed. have.

For example, when the movement of a finger is sequentially sensed along the boundary of the pointing area 120 at the boundary of the pointing area 120, a function of zooming in and out of the terminal may be performed, and the image or the web screen may be horizontally The vertical rotation, the intensity control of the volume, the direction and speed of the playback speed, and the forward and reward of the video may be variously defined.

In addition, it can be defined as a menu movement that can be accelerated by distinguishing the up and down adjustment according to the direction detection, for example, it can be used to quickly select a desired song from a stored playlist of a plurality of songs.

In addition, the pointing device according to the present embodiment may perform a function similar to a mouse of a computer, and may use the PS / 2 protocol used in a general computer mouse.

Referring to FIG. 5, a left click and a right click acting on a mouse of a general computer may be applied. For example, an operation corresponding to a click may be detected by finger contact for a predetermined time at the boundary of the pointing area 120. It may be assumed that a user touches the boundary of the pointing area 120 with a finger as a click. In this case, the terminal may be connected to the left click and the right click of the computer depending on whether the boundary of the left or right pointing area 120 is detected. Identify the corresponding commands. Of course, since the click of the up / down pointing area 120 is also available, its utilization may be more than the mouse of a computer.

In addition, one-click or double-click can be distinguished according to the number of click signals through the boundary of the pointing area 120. Through such a classification, a computer user environment familiar to the general user can be equally applied to a small terminal. .

In addition, when a click through the boundary of the pointing area 120 lasts for a predetermined time, it may be designed so that another function that can be distinguished from a short time click may be performed, for example, a contact state of the click for about 1 second or more. If is maintained, the mode is switched to the possible mode, such as, after that to move the finger to the direction electrode 130 to adjust the radiation area.

Although the above-described and illustrated embodiments of the present invention have been described with an example configured to perform other functions distinguished from the direction detection through the detection of movement of a finger at the boundary of the pointing area, in some cases, at the boundary of the pointing area. By detecting the movement of a finger, the direction detection function by the direction electrode can be assisted.

Meanwhile, in response to an object such as a finger moving out of the pointing area 120 while moving inside the pointing area 120, a signal is detected at the boundary of the pointing area 120 during the pointer or menu movement according to the direction detection. If is detected, the program can be adjusted so that the pointer or menu movement function by the direction electrode 130 is limited in whole or in part, and the malfunction that may occur in the outer portion of the direction electrode 130 may be minimized.

6 to 10 illustrate a flexible circuit board of a pointing device according to another embodiment of the present invention.

Referring to FIG. 6, a flexible circuit board structure of a pointing device including a direction electrode 130 of a 3 * 3 lattice arrangement described in the previous embodiment is disclosed. Each of the directional electrodes 130 may be electrically connected to the microchip 10 on the right side in a 1: 1 manner and may be connected to the main circuit board of the terminal through ordinary connection terminals.

In the above-described and illustrated embodiments of the present invention, an example of a pointing device including a 3 * 3 lattice array of direction electrodes is described. However, in some cases, as shown in FIG. 7, the direction electrodes 130 of a 5 * 5 grid array are illustrated. ) Can be used. Like the above-described embodiment, each of the directional electrodes 130 are electrically connected to the microchip 10 on the right side in a 1: 1 manner, and may be connected to the main circuit board of the terminal through ordinary connection terminals. Alternatively, the directional electrodes may be provided to have a 2 * 2 lattice arrangement, a 4 * 4 lattice arrangement, or a 6 * 6 or more lattice arrangement.

Referring to FIG. 8, a flexible circuit board structure of a pointing device in which a direction electrode 230 having a circular shape is arranged in a circular array is disclosed.

Hereinafter, a circular center electrode 232 having a circular electrode disposed inside the pointing area 220 and a circular radiation electrode 234 having an isometric angle along the radial direction with respect to the center electrode 232. An example including the configuration will be described. In some cases, as shown in FIG. 9, two or more rows of radiation electrodes may be arranged based on the center electrode. Each of the directional electrodes 230 may be electrically connected to the microchip on the right side in a 1: 1 manner and may be connected to the main circuit board of the terminal through ordinary connection terminals.

In addition, even when the direction electrode 230 is disposed in a circular shape as shown in FIGS. 8 and 9, when a movement of a finger is detected at the boundary of the pointing area 220, another function distinct from the direction detection may be performed.

In addition, when the pointing area is provided in a very small space such as within about 1 cm * 1 cm, it is advantageous that the direction electrodes are arranged in a circular arrangement (radial arrangement) rather than a lattice arrangement. That is, in the case of the circular array, since each of the radiation electrodes can be symmetrically disposed (the same distance from the center electrode) with respect to the center electrode, the movement of the finger can be detected more efficiently.

Referring to FIG. 10, a flexible circuit board structure of a pointing device including a direction electrode 330 arranged in a chrysanthemum shape is disclosed.

The direction electrode includes a center electrode 332 disposed inside the pointing area 320 and a radiation electrode 334 arranged at an equal angle along the radiation direction with respect to the center electrode 332, wherein the radiation electrode 334 Silver may be provided to have a size that extends from one end adjacent to the center electrode 332 toward the other end, and may be disposed to form an approximately chrysanthemum shape with the center electrode 332. In this structure, as described above, when the movement of the finger is detected at the boundary of the pointing area 320, another function distinguished from the direction detection may be performed. In addition, the direction electrodes 330 arranged in a chrysanthemum shape as described above has an advantage that the respective radiation electrodes 334 may be disposed closer to the center electrode 332.

Meanwhile, as shown in FIGS. 8 and 10, ground electrodes 236 and 336 for electrically shielding connection lines of other direction electrodes adjacent to the direction electrodes in which the finger is detected among the plurality of direction electrodes may be provided.

That is, when a finger is located at a specific direction electrode, it may change electrical characteristics such as capacitance to or around the corresponding direction electrode, and the change of the electrical characteristic is connected to another direction electrode adjacent to the direction electrode where the finger is detected. In this case, noise may be generated in the calculation of the finger movement. However, in the present invention, the ground electrode can be used to prevent a change in electrical characteristics generated during the detection of a finger at a specific direction electrode affecting the connection line of another adjacent direction electrode.

The ground electrodes 236 and 336 may be provided in various structures according to required conditions and design specifications.

For example, as shown in FIG. 8, the ground electrode 236 may be planarly provided between the respective direction electrodes 232 and 234, and the finger may be detected at the specific direction electrodes 232 and 234 by the ground electrode 236. It is possible to prevent the change in electrical characteristics generated during the influence on the connection line of the other adjacent direction electrode.

Alternatively, as shown in FIG. 10, the ground electrode 336 may be provided under the respective direction electrodes 332 and 334 with a via hole 336a through which the connection line 334a of each direction electrode 332 and 334 passes. The connection line 334a of each of the directional electrodes 332 and 334 may be disposed under the ground electrode 336 through the via hole 336a. As such, since the connection line 334a of each of the direction electrodes 332 and 334 is disposed under the ground electrode 336, the electrical characteristic change generated during the detection of the finger at the specific direction electrodes 332 and 334 is different from each other. It is possible to more effectively prevent affecting the connection line of the directional electrode.

11 is a view for explaining the structure of the directional electrode of the pointing device according to another embodiment of the present invention.

Referring to FIG. 11, the personal handheld terminal according to the present embodiment also provides a pointing area 420 on the substrate 435, and detects a direction when a finger movement is detected at the boundary of the pointing area 320 using a direction electrode. Can perform other functions that are distinct from

A direction electrode is provided in the pointing area 420, and the direction electrode is electrically separated from the upper electrode 432 and the upper electrode 432 disposed in the pointing area 420 in a planar manner. And a lower electrode layer 434 positioned under the 432.

The lower electrode layer 434 is formed on the bottom surface of the substrate 435, and can generate the entire pulse signal transmitted from the outside. When the finger is located on the specific upper electrode 432, the electrical characteristics such as capacitance may be changed to or around the upper electrode 432. In this case, the finger receives a changed pulse signal compared to other upper electrodes. By using this characteristic, the pointing device can detect the movement of the object.

This stacking structure is also somewhat more complicated than the direction electrode structure described in the above embodiments, but can be distinguished from direction detection, for example, scrolling, screen switching, page turning, rotation, zooming, speed or volume. Various functions such as adjustment can be performed.

Of course, the upper electrode 432 is also 1: 1 connected to the control chip of the terminal or the microchip of the pointing device, and the lower electrode layer 434 is a wide electrode and the microchip of the control chip or the pointing device of the terminal. It is connected.

While the present invention has been described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It can be understood that it is possible.
