In addition, the tabletop 100 recognizes whether the user has approached within the access recognition area through the access recognition unit. Table top 100 has a rectangular table form consisting of four sides. Accordingly, the approach recognition unit includes a first approach recognition sensor 126, a second approach recognition sensor 127, a third approach recognition sensor 128, and a fourth approach recognition sensor 129 disposed on each side.

In addition, the tabletop 100 recognizes whether the user approaches each side of the first area 121, the second area 122, the third area 123, and the fourth area 124. . For example, the first region 121 to the fourth region 124 may be in a range of about 1 to 1.5 m from the center of each side. That is, the access recognition area is an area in which the tabletop 100 recognizes the user's approach. In FIG. 1, the first area 121 to the fourth area 124 correspond to the access recognition area.

In addition, in the present specification, the direction of the first region 121 is the upward direction (upward direction), the direction of the second region 122 is the right direction (right direction), and the direction of the third region 123 is the downward direction ( The downward direction) and the direction of the fourth region 124 are defined as the left direction (left direction).

The first area 121 is an area where the user's approach is detected by the first access recognition sensor 126, and the second area 122 is an area where the user's approach is detected by the second access recognition sensor 127. The third area 123 is an area in which the user's approach is detected by the third access recognition sensor 128, and the fourth area 124 is detected by the fourth access recognition sensor 129. Area.

The tabletop 100 may recognize a user's approach using various types of access recognition units. In detail, the access recognition unit may use an ID card reader, a wireless communication module, or a human body sensor. For example, when the user accesses the ID card to the ID card reader, the tabletop 100 recognizes the user's access through the ID card reader. In addition, when the user has an ID card, the tabletop 100 may detect the ID card of the user through wireless communication such as RF, Zigbee, Bluetooth, and the like. In addition, the tabletop 100 may recognize the user's approach using a human body sensor using biometric authentication to recognize the user's voice, cornea, face or fingerprint. In addition, the tabletop 100 may recognize the user's ID card or the user's voice, cornea, face, or fingerprint, to recognize who the user is.

In addition, the tabletop 100 may recognize which direction the tabletop 100 has approached. For example, the table top 100 of FIG. 1 has four faces because it is a rectangular table. Accordingly, the tabletop 100 may recognize which of the four surfaces the user approaches.

To this end, the table top 100 may be provided with one approach recognition sensor on each of four surfaces. For example, the tabletop 100 of FIG. 1 may be equipped with four approach detection sensors on each side of the top, bottom, left and right. In addition, the tabletop 100 compares the strengths of the signals detected by the sensors, and recognizes that the user has approached the position of the sensor where the strongest signal is detected.

As such, the tabletop 100 may recognize whether the user has approached and in which direction the user has approached through the access recognition unit.

Hereinafter, the operation of the tabletop 100 when the user approaches it will be described with reference to FIGS. 2A to 2E.

2A is a diagram illustrating a screen displaying a user access recognition icon 210 when the tabletop 100 recognizes a user's approach and also recognizes a user's information according to an embodiment of the present invention.

As shown in FIG. 2A, when the user approaches the upper side of the tabletop 100, the tabletop 100 recognizes that the user has approached the upper side and displays the user access recognition icon 210 on the upper side of the screen. Mark it.

In addition, the tabletop 100 may recognize user information with the user's access. As shown in FIG. 2A, the user access recognition icon 210 displayed on the screen of the tabletop 100 may be identified as “user A”. That is, the tabletop 100 recognizes that the approaching user is “user A”.

The user information refers to information related to the user, and includes at least one of a user ID, a password, a user name, and a user picture.

Here, the user access recognition icon 210 refers to an icon displayed on the screen to indicate that the tabletop 100 recognizes that the user has approached the tabletop 100. In addition, when the user selects the user access recognition icon 210 while the user access recognition icon 210 is displayed on the screen, the tabletop 100 is approached by the user with the intention of using the tabletop 100. You will be judged. That is, the tabletop 100 uses the user access recognition icon 210 to distinguish whether the user intends to use the tabletop 100 or an accidental approach without the intention of using the tabletop 100. You can do it.

The user access recognition icon 210 may be displayed as an icon on the GUI, and at least one of the detected user information may be displayed together. For example, the user access recognition icon 210 may also display at least one of a user ID, a user name, and a photo image of the user.

On the other hand, when the tabletop 100 cannot recognize who the user is, the tabletop 100 recognizes the user as a guest. This will be described with reference to FIG. 2B.

2B is a diagram illustrating a screen displaying a user access recognition icon 220 when the tabletop 100 recognizes a user's approach and does not recognize the user's information, according to an embodiment of the present invention.

As shown in FIG. 2B, when the tabletop 100 recognizes only the user's access and does not recognize the user's information, the user may recognize that the "GUEST" is displayed on the user access recognition icon 220.

In addition, when the tabletop 100 does not recognize the user's information, the tabletop 100 may directly receive the user's information from the user. In detail, when the tabletop 100 does not recognize the user's information, the tabletop 100 displays a user information input screen. When all of the user information is input by the user, the tabletop 100 stores the input user information and displays the ID of the user input in the user access recognition icon 220.

In addition, the user access recognition icon 220 may be displayed at various locations. This will be described in detail with reference to FIG. 2C. 2C is a diagram illustrating a screen displaying a user access recognition icon 230 when a user approaches the left side of the tabletop 100 according to an exemplary embodiment.

The tabletop 100 displays the user access recognition icon 230 in different locations according to the direction in which the user approaches. That is, the tabletop 100 displays a user access recognition icon on a screen area in a direction corresponding to the approaching direction of the user. This is for the user to easily recognize the user access recognition icon 230 by displaying the user access recognition icon 230 in the screen area near the user access position.

Therefore, as shown in FIG. 2C, when the user approaches the left side of the tabletop 100, the user access recognition icon 230 is displayed on the left side of the screen.

As such, the tabletop 100 displays the user access recognition icon on the screen near the user's approach direction. Therefore, the user can intuitively recognize that the user access recognition icon is displayed due to his access.

Meanwhile, in the present exemplary embodiment, the tabletop 100 displays the user access recognition icon 230 to notify the user's access. However, other methods of accessing the user may be used. Specifically, the user access notification means may be implemented using a light emitting element or a sound. A case where the user access notification means is a light emitting device will be described in detail below with reference to FIG. 2D.

2D is a diagram illustrating a case where the user access notification means is a light emitting device according to another embodiment of the present invention. As shown in FIG. 2D, the table top 100 includes a first light emitting device 250, a second light emitting device 252, a third light emitting device 254, and a fourth light emitting device 256 on each surface thereof.

When the user approaches the tabletop 100, the tabletop 100 emits light emitting devices having a surface recognized as approached by the user. In the case of FIG. 2D, since the user approaches the upper surface of the tabletop 100, the tabletop 100 emits light of the first light emitting device 250 disposed above.

As such, the tabletop 100 may display that the user's approach is recognized by using the light emitting device.

2E is a diagram illustrating a user access recognition icon 260 displayed on the tabletop 100 being moved together when the user moves a location according to an embodiment of the present invention. As shown in FIG. 2E, when the user moves to the left side of the tabletop 100, the user access recognition icon 260 moves from the upper portion of the screen to the left portion. That is, when the user moves the position, the tabletop 100 moves the position of the displayed user access recognition icon 260 to the position where the user moved.

In addition, while the tabletop 100 moves the user access recognition icon 260 on the screen according to the user's moved position, the bottom of the user access recognition icon 260 is displayed to face outward of the screen. The user access recognition icon 260 is moved. As shown in FIG. 2E, when the user access recognition icon 260 is moved from the top of the screen to the left side, the bottom portion of the user access recognition icon 260 is directed toward the outside of the screen to maintain the screen. You can see that it has changed to face upward on the screen and then toward the left side of the screen. This is to allow the user access recognition icon 260 to be viewed in the forward direction instead of being flipped or skewed in any direction.

As such, since the tabletop 100 moves the user access recognition icon 260 displayed on the screen according to the position of the user, the user can more conveniently touch the user recognition icon 260.

Hereinafter, the personalization area will be described in detail with reference to FIGS. 3A to 3C. 3A is a diagram illustrating a user touching a user access recognition icon 310 according to an embodiment of the present invention.

When the tabletop 100 displays a user access recognition icon indicating that the user access is recognized on the screen, the user can select the user access recognition icon displayed on the screen to use the tabletop 100. That is, when the user selects a user access recognition icon, the tabletop 100 displays a menu suitable for the user on the screen. For example, the screen of the tabletop 100 is a touch screen, and the user may start using the tabletop 100 by touching a user access recognition icon.

3B is a diagram illustrating a screen on which the personalization area 320 is displayed, according to an embodiment of the present invention. As shown in FIG. 3B, when a user touches a user access recognition icon of the tabletop 100, the tabletop 100 displays a personalization area 320, which is a screen area that the user can use, on the screen. The tabletop 100 displays the personalization area 320 in a screen area in a direction corresponding to the approach direction of the user. The tabletop 100 displays the personalization area 320 in a screen area close to the user, so that the user can use the personalization area 320 more conveniently.

Herein, the personalization area 320 refers to a screen area allocated for use by a user in the screen area of the tabletop 100. The remaining area of the tabletop 100 except for the personalization area 320 becomes a shared area that all users use together. In the personalization area, a menu suitable for personal use by the user is displayed.

For example, the personalization area 320 displays a user's personal folder stored in the tabletop 100, a shared folder of the user's personal computer, a personal blog of an Internet website, and a list of friends connected on the network.

In addition, the personalization area 320 may automatically display an application having a high usage rate for each time zone. In this case, the tabletop 100 may determine which application the user uses for each time zone by referring to the log of the application for each user. For example, if the user checks the mail on the tabletop 100 every Wednesday at 3:00 pm, the tabletop 100 displays an icon in the personalization area 320 that executes the mail application in the personalization area at 3:00 pm. Will be displayed.

In the case of FIG. 3B, the personalization area 320 shows a state where a personal folder 321, a favorite 323, and a PC shared folder 325 menu are displayed. However, the personalization area 320 may be displayed in addition to any menu that can be used by the user.

As such, since the tabletop 100 displays the personalization area 320 for each user on the screen, the user can be assigned to use the personal area of the tabletop 100.

3C is a diagram illustrating that the personalization area 320 displayed on the tabletop 100 moves together when the user moves the location according to an embodiment of the present invention. As shown in FIG. 3C, when the user is on the upper side of the tabletop 100 and moves to the left side, the personalization area 320 is moved from the upper part of the screen to the left part. That is, when the user moves the position, the tabletop 100 moves the displayed personalization area 320 to the position where the user moves.

In addition, while the tabletop 100 moves the personalization area 320 on the screen according to the user's moved position, the personalization area 320 is displayed in such a manner that the bottom of the personalization area 320 is directed outward of the screen. Move). As shown in FIG. 3C, when the personalization area 320 is moved from the top of the screen to the left side, the bottom portion of the personalization area 320 is directed upward of the screen to maintain the outward direction of the screen. You can see that it has changed to face the left side of the screen. This is to allow the user to view the personalization area 320 in the forward direction instead of being flipped or skewed in any direction.

As such, since the tabletop 100 moves the personalization area 320 displayed on the screen according to the position of the user, the user can use the personalization area 320 more conveniently.

Hereinafter, referring to FIG. 4, a case in which the user ends the use of the tabletop 100 will be described. FIG. 4 is a diagram illustrating that the personalization area 320 of the tabletop 100 disappears when the user leaves the fourth area 124 of the tabletop 100.

As shown in FIG. 4, when the user leaves the fourth area 124, the access recognition unit of the tabletop 100 no longer recognizes the user's approach. Therefore, the tabletop 100 determines that the user ends the use, and causes the personalization area 320 to disappear from the screen.

In addition, the tabletop 100 may have a waiting time of a predetermined time even if the user leaves the fourth area 124. That is, even if the user leaves the fourth area 124, when the user returns to the fourth area 124 again within the waiting time, the tabletop 100 continues to display the personalization area 320 on the screen. On the other hand, when the user leaves the fourth area 124 and the waiting time elapses, the tabletop 100 causes the personalization area 320 to disappear from the screen.

The tabletop 100 stores the information about the personalization area in the memory for a certain time of reuse even if the user leaves the fourth area 124. Therefore, when the user approaches the fourth area 124 again within the reusable time, the tabletop 100 displays the personalization area that the user previously used on the screen as it is. Through this, the user can easily reuse the tabletop 100 even if the user accidentally deviates from the fourth region 124.

In the description of FIG. 4, the case in which the access recognition area is the fourth area 124 has been described as an example, but it can be applied to other access recognition areas. For example, it may be applied to the first region 121, the second region 122, and the third region 123 of FIG. 1.

So far, with reference to FIGS. 1 to 4, the user-specific UI providing method through the user access recognition and personalization area providing process of the tabletop 100 has been described in detail.

In the present embodiment, only a case where one user uses the tabletop 100 has been described, but the tabletop 100 may be used simultaneously by a plurality of users. In this case, the tabletop 100 allocates a personalization area to each user and displays it on the screen. This will be described with reference to FIG. 5.

5 is a diagram illustrating a case where two users use the tabletop 100 according to an exemplary embodiment of the present invention. As shown in FIG. 5. The tabletop 100 may confirm that the personalization area 510 of the user A and the personalization area 520 of the user B are displayed on the screen. In this manner, the tabletop 100 may be used by two or more users at the same time. The tabletop 100 displays a user access recognition icon and a personalization area for each user.

In addition, the tabletop 100 may transmit and receive data with each other through the personalization area of each user. For example, if user A drags a file displayed in his personalization area 510 to user B's personalization area 520, the top table 100 drags the dragged file from user A's personalization area 510. Copy to user B's personalization area 520.

Meanwhile, in the present embodiment, only the case where there is one tabletop 100 is described, but it is a matter of course that two or more tabletops may be applied to an environment connected to each other. This will be described with reference to FIG. 6.

6 is a diagram illustrating a case in which the smart board 600 and the tabletop 100 are interlocked with each other according to an embodiment of the present invention. As shown in FIG. 6, the smart board 600 and the tabletop 100 are communicatively connected to each other through a wired / wireless communication module. In addition, the smart board 600, like the tabletop 100, it is possible to recognize the user access.

When the user moves from the tabletop 100 to the smart board 600, the tabletop 100 transmits information about the personalization area 610 of the user to the smart board 600.
