Including, in the case of center area pointing, the center touch pad 111 is used alone, and in the case of complex area pointing, the center touch pad 111 and the side touch pads 112a, b, c, and d are combined. The multi-region pointing starts with the touch of the center touch pad 111 and remembers the touch response sensitivity when reaching the corresponding side touch pads 112a, b, c, and d, and the side touch As long as the pad 112a, b, c, and d is reached and the touch is maintained, the movement continues according to the memorized touch response sensitivity even if the touch is not repeatedly touched. By performing pointing, a desired amount of pointing can be performed even with a very small area of the touchpads 110 and 120 .

First, as shown in FIGS. 3 and 4 , the touchpads 110 and 120 are formed in a disk shape and perform pointing by recognizing pointing coordinates by a touch of a touch sensor (not shown).

For example, the touchpads 110 and 120 include the center touchpad 111 for performing center area pointing alone, and the side touchpad for performing complex area pointing and various basic functions of the touchpad and additional functions not provided by the existing touchpads. It can be divided into (112a, b, c, d).

Here, the side touch pads 112a, b, c, and d are formed with a STU (Side Touch Up) 112a and STD (Side Touch Down) 112b at equal intervals by a second dividing boundary film 122 to be described later. Each of the side touch pads of the STL (Side Touch Left) 112c and the STR (Side Touch Right) 112d may be divided into four and configured.

On the other hand, specifically, multi-region pointing causes the touch response sensitivity when the touch starts from the center touch pad 111 and reaches the corresponding side touch pads 112a, b, c, and d to be remembered and the side touch pad 112a , b, c, d) is reached and the touch is maintained, and it is designed to continue moving according to the memorized touch response sensitivity without repeated touch. can make it

Of course, in this case, the technical configuration used for moving by storing the touch sensitivity may be selectively applied according to product design.

Here, the dividing boundary film 120 is set to a height of 0.2 mm to 0.4 mm, and is set to a level at which the boundary between the center touch pad 111 and the side touch pads 112a, b, c, and d is recognized. However, when interlocking by a specific combination of the center touch pad 111 and the side touch pads 112a, b, c, and d for multi-region pointing, the height may be set to a level at which the boundary can be easily crossed while touching.

That is, the dividing boundary layers 121 and 122 divide the touchpads 110 and 120 to perform various and subdivided functions, and each of the center touchpad 111 and the side touchpads 112a, b, c, and d respectively. In order to prevent a malfunction that exceeds the boundary of the set optional function, the user can easily recognize the physical boundary between the first partitioning layer 121 and the second partitioning layer 122 with the tactile sense of a finger.

Next, as shown in FIGS. 2 and 4 , the button frame 130 serves as a housing (A) for accommodating the touchpads 110 and 120 so that the upper portions of the touchpads 110 and 120 are exposed while the outer area is divided into a second It is divided by the boundary film 122 and configured to perform the button frame function B by pressing the corresponding side touch pads 112a, b, c, and d.

Here, the button frame 130 is formed at equal intervals by the second dividing boundary film 122, SBU (Side Button Up) 132a, SBD (Side Button Down) 132b, and SBL (Side Button Left) ( 132c) and the SBR (Side Button Right) 132d may be divided into 4 corresponding button frames.

On the other hand, the center touch pad 111, the side touch pads 112a, b, c, d) or the button frame 130 alone or in a specific combination to faithfully perform various functions of basic and additional functions as a graphic controller. can

Next, the main circuit board 140 is provided at the lower end of the button frame as shown in FIG. 4 , and the button frame contact 142 is provided on the main circuit board 140 .

That is, on the main circuit board 140 , two or more elastic button frame contacts 142 are arranged in a radial form in the outer region corresponding to the button frame 130 and electrically connected by pressing the button frame 130 . ) can be formed respectively.

For example, as shown in FIG. 4 , first to fourth button frame contacts corresponding to SBU, SBD, SBL and SBR may be formed, respectively.

In addition, the corresponding one button frame contact is energized by pressing of one button frame, so that the click, double click, and long press of the button frame are recognized, respectively.

Meanwhile, the circuit line C composed of the touch pad wiring line and the button frame wiring line may be electrically connected to a connection terminal (not shown) of an external device.

thus. The touch input module 100 according to the present invention as described above is performed independently by the center touchpad when pointing in the center area, and in parallel by the combination of the center touchpad and the side touchpad when pointing in the complex area. , it is possible to overcome spatial limitations by performing a pointing function in a fixed space without physical movement, and provides various additional functions not provided by existing touchpads by single and combined operation of the divided touchpad and button frame. , It can be attached without any sense of rejection or foreign body or can be manufactured in various shapes without size restrictions.

Meanwhile, the touch input module 100 according to the present invention may be configured as a separate element in which the center touchpad and each side touchpad are physically separated.

That is, in the case of the above-described embodiment, the touchpad is configured as a single circular touch panel, and commands are received by dividing it into a center area and a side area in software, but differently arranged in the center area and each side area The touch panel to be used may be configured with separate touch panel elements.

Summarizing the structural features of the present invention as described above, first, the present invention has a feature in which up/down/left/right click buttons are added in hardware.

That is, the present invention provides additional functions by providing additional up, down, left, and right buttons so that clicks can be performed on the main board at the lower points of the upper and lower (left and right) sides of the touch pad while maintaining the left and right click buttons of the existing touch pad. made it possible to perform.

In this way, by providing buttons on the upper, lower, left, and right lower portions of the touchpad surface, single press (click), double press (double click), and long press can be performed, so these buttons are operated independently. Even so, at least 6 functions can be additionally performed.

In addition, the present invention has a feature of operating the touch sensor by area division and binary driving method in software.

Specifically, as shown in FIG. 7, the present invention divides the entire area of the touch pad sensor into the center and 4 outer areas, and each outer area is divided into two independent areas of 8 sensors to drive the IC chip of the touch sensor. was designed/programmed.

In addition, in the present invention, the central area recognizes the touch itself as an event like the existing touchpad, or reads the X and Y coordinates of the starting point and the moving point to determine the moving direction and distance and transmits the result. Although the outer area sensor appears to be divided into 4 on the outside due to the area dividing film of the sensor cover provided in the rest of the divided outer area, in reality, the outer area sensor is divided into 8 areas in consideration of the expansion of additional functions. configured to be divided.

In this way, each sensor divided and independent recognizes the touch itself as an event like the driving method of the central area sensor, or reads the X and Y coordinates of the starting point and the moving point to deliver the result of determining the moving direction and distance ( Action) Not only does it play a role in judging, but even if a touch is made in any form, the touch itself is simply recognized as an event that has occurred. The IC chip of the touch sensor is implemented.

As such, the outer area sensors operated in the dual drive method are set to be operated as one drive method by another IC chip program of the main board according to the performance function whether operated alone or in combination.

In addition, the present invention is provided with a dividing boundary film to distinguish each region, and since the sensor region is designed to be divided by software, the user clearly recognizes and touches the divided sensor region visually and tactilely, There are features that can perform functions.

In the present invention, as the dividing boundary film is formed to protrude near the periphery of the touchpad (about 40% of the circumference of the touchpad), when a button provided under the outer sensor on the upper, lower, left, and right surfaces of the touchpad is pressed, the protruding protrusion The protruding shape of the dividing boundary film has a characteristic that not only guides the button but also obtains the effect of pressing.

In addition, in the present invention, the dividing boundary film is small in size and precise, so the manufacturing difficulty is high. When it is separately manufactured and attached to the upper part of the sheet of the touch pad, costs are added in the manufacturing and attachment process. Accordingly, the dividing boundary film of the present invention is manufactured in one mold integrally with the sheet of the touch pad, thereby increasing the efficiency and economic feasibility of manufacturing.

On the other hand, looking at the functional features of the present invention, the present invention has a feature that can perform an additional input function that could not be implemented in the conventional Dutch pad while performing the input function of the existing touch pad as it is.

That is, the present invention recognizes the touch itself in the central area of the divided sensor in terms of software like the existing touchpad module, or reads the X and Y coordinates of the starting point and the moving point to determine the moving direction and distance to determine the result. It maintains the driving method of delivering By maintaining the user environment (user interface: UI), touch (double touch) and left and right clicks (double click) on the touchpad perform basic functions such as pointing, scrolling, drag and drop, and menu popup.

In addition to this, an additional input function that can be performed in the present invention is as follows.

(1) long pointing

In order to perform pointing at a longer distance than the limited area of the touchpad in a general touchpad, it is necessary to continuously perform pointing in a desired direction by breaking the touchpad several times to perform pointing in a desired direction. A drive mechanism is provided to make this possible.

Specifically, in the present invention, first, in the central touch area of the divided touch pad, a speed and direction are designated to a desired place and pointing is performed, and when the divided outer touch area is reached, the pointing continues and the touch is performed only when the desired place is pointed. Pointing ends when you release your hand from the pad.

That is, pointing is performed in the same driving method as the existing touchpad that reads the X and Y coordinates of the starting point and the moving points in the central area and delivers the result of determining the movement direction. The moment the touch is reached and touched, the touch itself is recognized as an event, i.e., the same as pressing a button that executes a command to continue in the pointing direction according to the set program, and pointing is continued.

In the end, when the central area sensor and the sensor of the divided outer area are combined and the preceding sensor area recognizes an action (direction and distance), the trailing outer sensor area recognizes other functions and acts as a button. Long pointing is possible with just one pointing by dualizing and operating the drive method to do this.

Accordingly, compared to a conventional touchpad, long pointing can be performed with a simple manipulation, and input errors can be significantly reduced compared to a case where long pointing is performed using a conventional touchpad.

(2) Drag and drop

In the present invention, drag and drop is performed in the center area sensor in the same way as the existing touch pad. In a more convenient way, drag and drop can be performed in just one attempt in two ways different from the existing touch pad as shown below. there is.

The first is long drag and drop. As in the case of the above-mentioned long pointing, the program is designed so that when the center area sensor holds the direction and drags and reaches the outer sensor area (ST), it recognizes that an event has occurred and continues. It means that the drag can drop to the desired point by itself.

Next, the second is location selection and movement long drag-and-drop, which is when you touch in the central sensor area (CT) and touch the outer sensor area (UST). This means that the touch is released only when the desired point is reached without interruption even after performing dragging several times in the desired point and direction as if pointing, such as holding the clicked state.

In other words, even when dragging and dropping on the existing touchpad, it cannot reach the desired place at once, so it tries several times to reach the desired place. In order to prevent this, in the existing touchpad, left-click the touchpad with one hand to keep it clicked and use the other hand to reach the desired point. However, long drag and drop can be performed on the existing touchpad, but in the present invention, as in the prior art, the function is performed with one hand without the inconvenience of maintaining the left click with one hand and performing the function with the other hand. In doing so, the ease of use is improved.

(3) Scroll (wheel key)

The interface device according to the present invention provides short-distance scrolling and long-distance scrolling functions. As shown in FIG. 8, the short-distance scrolling uses the touchpad to move the left and right side touchpads up and down as if the wheel keys of the mouse operate. Alternatively, up and down scrolling is performed by moving as if pointing backwards, and left and right scrolling can be performed by moving the upper and lower side touchpads left and right or reversely.

To this end, the touch area of the left and right side touch pads may be divided into upper and lower portions, and the upper and lower side touch pads may be programmed with the touch areas divided into left and right sides.

In this way, when scrolling is performed, the side touch pad may be designed to recognize the movement direction and distance of the touch.

On the other hand, in the long scroll according to the present invention, similar to the short-distance scroll described above, as shown in FIG. 9D , the upper and lower scrolls are performed while touching the left and right areas of the side touch pad, and the boundary (divided boundary layer) of the touch area is set. When the upper or lower side touchpad area is reached, in this case, the moment a touch is made on the upper/lower side touchpad area, the touch itself is recognized as an event and a command to continue in the pointing direction is executed according to the set program. Thus, it is recognized that scrolling continues in the moving direction, and the scrolling is stopped only when the release of the touch is sensed.

In the end, single-touch execution (performing seamless scrolling) is made possible by dividing the sensor to set the binary driving method and operating the driving method selected by the program when the divided sensors perform a function in combination. Therefore, the same driving principle is applied even in the case of left and right scrolling.

(4) hot key

The interface device according to the present invention additionally includes click buttons (side buttons) on the upper/lower/left/right sides of the touchpad, so that various functions can be set as hotkeys and operated by these alone or in combination.

Furthermore, although performing functions can be added according to button operation, when the division area of the button and the touch sensor is operated in combination, more additional functions can be performed, and as side buttons are provided in all four directions, , Corresponding to the position of the function icon set on the window screen, the same function can be set as a hot key on each side touch panel and used.

In this case, since the layout structure of the window screen familiar to the user can be reflected in the hotkey function assignment of each side touch panel, the user can intuitively understand the function of each hotkey, so that multiple hotkeys can be used without confusion. convenience is provided.

For example, back (<-), window full screen (□), window reduction (▣), and close (× functions are operated by touching the icon located on the top bar of the window screen on the web browser. Since it is disposed at the top (from left to right), the intuitive usability of the user increases when a hotkey is set in response to the same function as the upper side button of the touchpad.

Also, in the case of the hide (-) function, since it is hidden under the screen when it is executed, the hotkey for the corresponding function can be assigned to the lower side button of the touchpad to improve intuition.

(5) Keyboard function (letter, number, sign input)

The interface device according to the present invention operates an external button provided with an LED on the upper part of the case to switch to the character mode, and characters, numbers, By allocating a key value such as a sign, it is possible to perform an input function such as a character, a number sign, etc., such as a keyboard, by performing a combination operation.

(6) Laser pointer function

The interface device according to the present invention can perform the function of a presenter by mounting a laser pointer on one side of the case. In other words, if you use the touchpad module and click button together with the laser pointer, you can integrate and perform the function as a presenter for expert meetings that require not only general PowerPoint PT, but also various reference materials and reference sites. .

The right of the present invention is not limited to the above-described embodiments, but is defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. it is self-evident

The present invention relates to a wireless interface device capable of inputting more various user commands without errors with a touchpad having a smaller area than the conventional touchpad by resetting the operating principle by fusing the advantages of the existing mouse and touchpad, In the present invention, there is an effect that can be performed independently by the center touchpad during short-distance pointing, and concurrently by a combination of the center touchpad and the side touchpad during long-distance pointing.
