In FIG. 2, the sensors 4 </ b> A to 4 </ b> D are incorporated in the respective sides 5 </ b> A to 5 </ b> D of the table 5, but the number of sensors is not limited to four. For example, it is not always necessary to incorporate sensors on all sides of the table 5, and a configuration in which corresponding sensors are incorporated on at least two or more sides of the table may be employed. For example, the sensors 4A and 4C may be incorporated in the opposing sides 5A and 5C, respectively.

(PC3 for display control)
The display device control PC 3 receives information from the storage unit 31 that stores data, the display device 2 and the sensors 4A to 4D, and communicates with the main control unit 32 that controls the display device 2 and the display device 2. And a communication unit 36 for performing.

  The storage unit 31 is a storage device that stores various setting data and image data displayed on the display unit 24 of the display device 2.

  The main control unit 32 determines a user position determination unit 34 that determines the position of the user based on the user detection signal, and a display direction of an image displayed on the display unit 24 based on an input signal from the user position determination unit 34. A display direction determining unit (display setting unit) 33 is provided.

  The user position determination unit 34 receives the user detection signals from the sensors 4A to 4D, determines on which side of the table 5 the user exists based on the user detection signals, and indicates a user position determination indicating the determination result. Generate information. The user position determination unit 34 transmits the user position determination information to the display direction determination unit 33.

  Based on the user position determination information received from the user position determination unit 34, the display direction determination unit 33 displays the image on the display unit 24 so that an image is displayed in the front direction when viewed from the side where the user exists. Determine the display direction of the image. The display direction determination unit 33 transmits display direction information indicating the display direction of the determined image to the display control unit 23.

  That is, the display direction determination unit 33 sets the direction of the image displayed on the display unit 24 according to the user position detected by the sensors 4A to 4D that detect the user position with respect to the display unit 24.

  The display direction determination unit 33 may transmit the display direction information in order to change the display direction of the image already displayed on the display unit 24, and transmits the display direction information together with the image displayed on the display unit 24. May be. The image displayed on the display unit 24 and whose display direction is set or changed is not particularly limited, and may be a desktop background image, a user-specified image (still image or moving image), or a combination thereof. . In addition, the display direction determination unit 33 may determine a display direction serving as a reference for the entire screen of the display unit 24. In the case of this configuration, on the assumption that there are a plurality of users, an exceptional image (for example, a task bar) displayed in a direction different from the reference display direction may exist.

  The communication unit 36 may perform wired communication or wireless communication.

(Table 5)
The table 5 is a table in which the display device 2 is incorporated. The table 5 shown in FIG. 2 includes four legs, but the number of legs is not limited to four and may be any number. The “table” of the present invention means a table on which an object can be placed, and a table and a work table are also included in the concept of “table”.

(Flow of image display processing in display system 1)
Next, an example of the flow of image display processing in the display system 1 will be described. Here, in order to simplify the explanation, it is assumed that there is one user of the display system 1 and there are not a plurality of users. It is assumed that some image has already been displayed on the display unit 24.

  FIG. 3 is a flowchart illustrating an example of the flow of image display processing in the display system 1.

  First, the sensors 4A to 4D detect the presence or absence of the user (position detection step). When any one of the sensors 4A to 4D detects the presence of the user (YES in step S1), the sensor that has detected the presence of the user transmits a user detection signal to the user position determination unit 34.

  When the user position determination unit 34 receives the user detection signals from the sensors 4A to 4D, the user position determination unit 34 determines the position of the user based on the user detection signals, and sends the user position determination information indicating the determination result to the display direction determination unit 33. Send.

  The display direction determination unit 33 receives the user position determination information from the user position determination unit 34, and based on the user position determination information, an image is displayed in the front direction when viewed from the side where the user exists on the display unit 24. Thus, the display direction of the image is determined. That is, the display direction determination unit 33 sets the direction of the image displayed on the display device 2 in accordance with the position of the user detected in the position detection process (display setting process). The display direction determination unit 33 transmits display direction information indicating the determined display direction to the display control unit 23 via the communication units 36 and 26.

  The display control unit 23 receives the display direction information from the display direction determination unit 33 and displays the image on the display unit 24 according to the display direction information.

  That is, when there is a reaction to detect the presence of the user only in the sensor 4A, as shown in FIG. 4A, the display unit 24 displays an image in the front direction when viewed from the side 5A (step S2). .

  When there is a reaction to detect the presence of the user only in the sensor 4B, the display unit 24 displays an image in the front direction when viewed from the side 5B as shown in FIG. 4B (step S3).

  When there is a reaction for detecting the presence of the user only in the sensor 4C, the display unit 24 displays an image in the front direction as viewed from the side 5C as shown in FIG. 4C (step S4).

  When there is a reaction to detect the presence of the user only in the sensor 4D, as shown in FIG. 4D, the display unit 24 displays an image in the front direction when viewed from the side 5D (step S5).

  On the other hand, when none of the sensors 4 </ b> A to 4 </ b> D detects the presence of the user (NO in step S <b> 1), each sensor does not transmit a user detection signal to the user position determination unit 34. Further, the user position determination unit 34 also does not transmit the user position determination information to the display direction determination unit 33.

  In this case, the display direction determination unit 33 generates display direction information so that the display unit 24 displays an image in a default setting direction that is a predetermined direction. The display direction determination unit 33 transmits the display direction information to the display control unit 23.

  The display control unit 23 receives the display direction information from the display direction determination unit 33, and displays the image in the default setting direction on the display unit 24 in accordance with the display direction information (step S6).

  When an image is not displayed on the display unit 24, the display direction determination unit 33 displays display direction information indicating the determined display direction together with image data of the image displayed on the display unit 24. 23.

(Example of change)
In the above description, it is assumed that there is one user of the display system 1, but there may be a plurality of users of the display system 1. In this case, the configuration may be such that the user specifies the direction of the image displayed on the display unit 24. For example, when the display system 1 detects that a user exists on a plurality of sides of the table 5, a pop-up window (display direction) for the user to select the display direction of the main image whose display direction is to be changed is displayed. (Selection image) may be displayed. An example of the processing flow in this case will be described. Here, it is assumed that there are users on the sides 5A and 5B.

  When the user exists on the sides 5A and 5B of the table 5, the presence of the user is detected by the sensors 4A and 4B. Based on the user detection signals transmitted from the sensors 4A and 4B, the user position determining unit 34 determines that there are users at two locations 5A and 5B of the table 5.

  Based on the determination result of the user position determination unit 34, the display direction determination unit 33 displays 2 in the display unit 24 so that a pop-up window is displayed in the front direction when viewed from each of the sides 5A and 5B where the user exists. Determines the display position and display direction of the two pop-up windows. That is, when the sensors 4A to 4D detect a plurality of users existing at different positions, the display direction determination unit 33 is a pop-up subject to an input operation for the user to select the image display direction on the display unit 24. The window is displayed on the display screen of the display unit 24 via the display control unit 23. At this time, the display direction determination unit 33 sets the display position and display direction of the pop-up window according to the position of the user detected by the sensors 4A to 4D.

  The display control unit 23 displays a pop-up window on the display unit 24 at the display position and display direction determined by the display direction determination unit 33.

  FIG. 5 is a top view showing a screen of the display unit 24 in a state where the pop-up windows 25A and 25B are displayed. As shown in FIG. 5, the pop-up window 25A is displayed so as to be in the front direction when viewed from the side 5A, and the pop-up window 25B is displayed so as to be in the front direction when viewed from the side 5B.

  The pop-up windows 25A and 25B may be input areas for arbitrarily selecting the display direction of the main image. Alternatively, by pressing the input button (priority button) of the pop-up window 25A / 25B, the direction of the main image is changed so that the direction in which the pop-up window 25A / 25B is displayed becomes the front. Also good.

  When the user inputs to the pop-up window 25A or 25B, the touch position information generation unit 22 calculates the touch position on the pop-up window 25A or 25B by the user, and displays the touch position information indicating the touch position. It transmits to the display direction determination part 33 of PC3 for control.

  Based on the touch position information, the display direction determination unit 33 generates display direction information so that the display unit 24 displays the main image in the display direction selected by the user. The display direction determination unit 33 transmits the display direction information to the display control unit 23.

  The display control unit 23 receives the display direction information from the display direction determination unit 33 and displays the main image in the direction selected by the user on the display unit 24 according to the display direction information.

(Effect of display system 1)
FIG. 6 is a top view showing a screen of a conventional display device. As shown in FIG. 6, when the direction of the image displayed on the display screen does not change according to the position of the user, the position at which the user can easily visually recognize the displayed image is limited. . For example, in FIG. 6, the image displayed on the display screen is easy for a user who is present on the side 5 </ b> A, but is not easy for a user who is present on the sides 5 </ b> B to 5 </ b> D.

  On the other hand, in the display system 1, since the direction of the image displayed on the display screen changes according to the position of the user, the display system 1 exists on any side of the sides 5A to 5D as shown in FIG. It becomes easy for the user to visually recognize the image displayed on the display screen.

  The user position determination unit 34 receives the user detection signals from the sensors 4A to 4D, determines on which side of the table 5 the user exists based on the user detection signals, and indicates a user position determination indicating the determination result. Generate information. The user position determination unit 34 transmits the user position determination information to the taskbar display direction determination unit 35.

  The task bar display direction determination unit 35 receives the user position determination information from the user position determination unit 34, and based on the user position determination information, the task bar 27 is displayed on the side where the user exists on the display unit 24. Next, the display position and display direction of the task bar 27 on the display unit 24 are determined. That is, the taskbar display direction determination unit 35 sets the arrangement of the taskbar 27 on the display screen according to the position of the user detected by the sensors 4A to 4D.

  The task bar display direction determination unit 35 transmits task bar display information indicating the determined display position and display direction of the task bar 27 to the display control unit 23.

  The taskbar display direction determination unit 35 may transmit the taskbar display information in order to change the display position and display direction of the taskbar 27 already displayed on the display unit 24, and the taskbar display direction determination unit 35 may display the taskbar 27 displayed on the display unit 24. The task bar display information may be transmitted together with the image data.

(Flow of task bar display processing in display system 10)
Next, an example of a task bar display process flow in the display system 10 will be described. Unlike Embodiment 1, the user of the display system 10 may be singular or plural. For the sake of simplicity, it is assumed that the task bar 27 is already displayed on the display unit 24.

  FIG. 8 is a flowchart illustrating an example of the flow of task bar display processing in the display system 10.

  First, the sensors 4A to 4D detect the presence or absence of the user (position detection step). When one or more of the sensors 4A to 4D detect the presence of the user (YES in step S11), the sensor that detects the presence of the user transmits a user detection signal to the user position determination unit 34.

  Upon receiving the user detection signals from the sensors 4A to 4D, the user position determination unit 34 determines the position of the user based on the user detection signals, and displays user position determination information indicating the determination result as the task bar display direction determination unit 35. Send to.

  The task bar display direction determination unit 35 receives the user position determination information from the user position determination unit 34, and the task bar 27 is displayed on the side where the user exists on the display unit 24 based on the user position determination information. Thus, the display position and display direction of the task bar are determined (display setting step). The task bar display direction determination unit 35 transmits task bar display information indicating the determined display position and display direction of the task bar 27 to the display control unit 23.

  The display control unit 23 receives the task bar display information from the task bar display direction determination unit 35 and displays the task bar 27 on the display unit 24 according to the task bar display information.

  That is, when there is a reaction to detect the presence of the user in the sensor 4A, the display unit 24 displays the task bar 27 on the side 5A side as shown in FIG. 9A (step S12).

  When the sensor 4B has a reaction to detect the presence of the user, the display unit 24 displays the task bar 27 on the side 5B side as shown in FIG. 9B (step S13).

  When there is a reaction to detect the presence of the user in the sensor 4C, the display unit 24 displays the task bar 27 on the side 5C side as shown in FIG. 9C (step S14).

  When there is a reaction to detect the presence of the user in the sensor 4D, the display unit 24 displays the task bar 27 on the side 5D side as shown in FIG. 9D (step S15).

  Here, when there are a plurality of users, the display unit 24 displays the task bar 27 on all sides where the users exist.

  For example, when there are two users and the sensor 4A and the sensor 4C have reacted to detect the presence of the user, respectively, as shown in FIG. Each task bar 27 is displayed on the 5C side.

  When there are three users and the sensors 4A, 4B, and 4C react to detect the presence of the user, the display unit 24 displays the taskbars on the sides 5A, 5B, and 5C. 27 are displayed.

  In addition, when there are four users and the sensors 4A, 4B, 4C, and 4D each have a reaction to detect the presence of the user, the display unit 24 displays the sides 5A, 5B, and 5C. The task bar 27 is displayed on the side and the side 5D side.

  On the other hand, when none of the sensors 4 </ b> A to 4 </ b> D detects the presence of the user (NO in step S <b> 11), each sensor does not transmit a user detection signal to the user position determination unit 34. In addition, the user position determination unit 34 does not transmit the user position determination information to the taskbar display direction determination unit 35.

  In this case, the taskbar display direction determination unit 35 generates taskbar display information so that the display unit 24 displays the taskbar 27 on the default setting direction side, which is a predetermined direction. The taskbar display direction determination unit 35 transmits the taskbar display information to the display control unit 23.

  The display control unit 23 receives the task bar display information from the task bar display direction determination unit 35, and displays the task bar 27 on the default setting direction side on the display unit 24 according to the task bar display information (step S16).
