1-2. Flow chart of embodiment 1
Next, the processing executed by the display system 10 will be described with reference to fig. 2 to 6.
First, at S1, the 1 st display device 1 and the 2 nd display device 2 constituting the display system 10 enlarge and display the image (the 1 st image) output from the 1 st information processing device 3. This corresponds to the 1 st display mode of fig. 3. Here, in the present embodiment, when the 1 st display device 1 and the 2 nd display device 2 display images in an expanded manner, the switching region SR is set in a direction orthogonal to the arrangement direction of the 1 st display device 1 and the 2 nd display device 2. In the example of fig. 3, the switching region SR is set at an end portion of the 1 st display device 1 or the 2 nd display device 2 in the vertical direction, which is a direction orthogonal to the arrangement direction (lateral direction) of the 1 st display device 1 and the 2 nd display device 2. The reason why the switching region SR is set in the direction (vertical direction) orthogonal to the arrangement direction (horizontal direction) of the 1 st display device 1 and the 2 nd display device 2 is to suppress unnecessary switching processing when the pointing position PP is moved on the 1 st display device 1 and the 2 nd display device 2 by the operation unit 5. The position at which the switching region SR is set is not particularly limited, and may be set at any position, such as the lateral end of the 1 st display device 1 or the 2 nd display device 2. The switching region SR may be set on the 1 st image or the 2 nd image, or may be highlighted when the pointing position PP is superimposed.
Next, as shown in fig. 4, when the operating unit 5 is operated to move the pointing position PP into the switching region SR, the detection unit 34 detects the presence of the pointing position PP in the switching region SR in S2 of fig. 2. When the pointing position PP is detected by the detection unit 34, in S3, the 1 st information processing device 3 transmits a switching signal to the 1 st display device 1 and the 2 nd display device 2 in order to enlarge and display the 2 nd image on the 1 st display device 1 and the 2 nd display device 2 (2 nd display mode), as shown in fig. 4. Here, the switching signal is a signal for switching the image displayed in the 1 st display device 1 and the 2 nd display device 2 in an expanded manner from the 1 st image to the 2 nd image, in other words, for switching the display system 10 from the 1 st display mode to the 2 nd display mode. Thereby, the display system 10 switches from the 1 st display mode to the 2 nd display mode as shown in fig. 5. Note that fig. 5 shows a state where the pointing position PP is moved out of the switching region SR in S4. Thereby, the 2 nd display mode is continued. When the detection unit 34 does not detect the presence of the pointing position PP in the switching region SR, it waits until the detection of the presence of the pointing position PP in the switching region SR is detected.
Next, as shown in fig. 6, when the operating unit 5 is operated to move the pointing position PP into the switching region SR, the detection unit 44 detects the presence of the pointing position PP in the switching region SR in S5 of fig. 2. When the detection unit 44 detects the pointing position PP, the process returns to S1, and the 2 nd information processing device 4 transmits a switching signal to the 1 st display device 1 and the 2 nd display device 2 as shown in fig. 6 in order to enlarge and display the 1 st image (the 1 st display mode) on the 1 st display device 1 and the 2 nd display device 2. Thereby, the display system 10 is switched from the 2 nd display mode to the 1 st display mode, and is again in the state of fig. 3. When the presence of the pointing position PP in the switching region SR is not detected by the detection unit 44, the detection unit waits until the presence of the pointing position PP in the switching region SR is detected.
In fig. 3 to 6, the display switching unit 33 or the display switching unit 43 may display whether the image displayed on the 1 st display device 1 or the 2 nd display device 2 is the 1 st image or the 2 nd image on at least one of the 1 st display device 1 and the 2 nd display device 2. For example, after switching from the 1 st display mode to the 2 nd display mode, the characters of the "2 nd image" are displayed for a predetermined time on the entire screen of at least one of the 1 st display device and the 2 nd display device 2. In contrast, after switching from the 2 nd display mode to the 1 st display mode, the characters of the "1 st image" are displayed for a predetermined time on the entire screen of at least one of the 1 st display device 1 and the 2 nd display device 2. Further, these pieces of information may be displayed on at least one of the 1 st display device 1 and the 2 nd display device 2 by a predetermined operation using the operation unit 5. The 1 st display device 1 or the 2 nd display device 2 may be configured to be capable of displaying an electronic medical record.
As described above, the display system 10 according to embodiment 1 includes the display switching unit 33 and moves the pointing position PP to the switching region SR, thereby easily switching the images displayed (expanded) on the 1 st display device 1 and the 2 nd display device 2 between the 1 st image and the 2 nd image. The display switching unit 33 switches from the 1 st display mode to the 2 nd display mode when the pointing position PP is detected by the detection unit 34 in the 1 st display mode.
2. Embodiment 2
A display system 10 according to embodiment 2 of the present invention will be described below with reference to fig. 7 to 9. In the display system 10 according to embodiment 2, the switching region SR includes at least one of the 1 st switching region SR1 existing in the 1 st display device 1 and the 2 nd switching region SR2 existing in the 2 nd display device. When the detection unit 34 (detection unit 44) detects that the pointing position PP reaches the 1 st switching region SR1, the display switching unit 33 (display switching unit 43) is configured to switch from the 1 st display mode to the 2 nd display mode.
As shown in fig. 7, first, in S1, the 1 st display device 1 and the 2 nd display device 2 constituting the display system 10 display the image (the 1 st image) output from the 1 st information processing device 3 in an expanded state. This corresponds to the 1 st display mode of fig. 8A.
Next, as shown in fig. 8A, when the operating unit 5 is operated to move the pointing position PP into the 1 st switching region SR1, the presence of the pointing position PP in the 1 st switching region SR1 is detected by the detector 34 in S2 of fig. 7. When the pointing position PP is detected by the detection unit 34, in S3, the 1 st information processing device 3 transmits a switching signal to the 1 st display device 1 and the 2 nd display device 2 so that the 2 nd image is displayed in an expanded state (the 2 nd display mode) on the 1 st display device 1 and the 2 nd display device 2. Thereby, the display system 10 switches from the 1 st display mode to the 2 nd display mode as shown in fig. 8B. Fig. 8B shows a state where the pointing position PP is moved out of the handover region SR in S4. Thereby, the 2 nd display mode is continued. When the detection unit 34 does not detect the presence of the pointing position PP in the 1 st switching range SR1, it waits until the presence of the pointing position PP in the 1 st switching range SR1 is detected.
Next, as shown in fig. 9A, when the operating unit 5 is operated to move the pointing position PP into the 2 nd switching region SR2, the presence of the pointing position PP in the 2 nd switching region SR2 is detected by the detector 44 in S5 of fig. 7. When the pointing position PP is not detected by the detection unit 44, the process returns to S1, and the 2 nd information processing device 4 transmits the switching signal to the 1 st display device 1 and the 2 nd display device 2 so that the 1 st image is displayed in the enlarged manner (the 1 st display mode) on the 1 st display device 1 and the 2 nd display device 2. Thereby, the display system 10 is switched from the 2 nd display mode to the 1 st display mode, and the state of fig. 9B is obtained. When the detection unit 44 does not detect the presence of the pointing position PP in the 2 nd switching range SR2, it waits until the presence of the pointing position PP in the 2 nd switching range SR2 is detected.
As described above, in the display system 10 according to embodiment 2, when the pointing position PP reaches the 1 st switching region SR1 when the 1 st image is displayed in an expanded state (the 1 st display mode) on the 1 st display device 1 and the 2 nd display device 2, switching from the 1 st display mode to the 2 nd display mode is performed. When the pointing position PP reaches the 2 nd switching region SR2 in the 2 nd image expansion display (2 nd display mode) on the 1 st display device 1 and the 2 nd display device 2, switching from the 2 nd display mode to the 1 st display mode is performed.
In other words, when the image displayed in the enlarged manner on the 1 st display device 1 and the 2 nd display device 2 is the 1 st image, only the 1 st switching region SR1 provided in the 1 st display device 1 is reflected in the pointing position PP, and the 1 st display device 1 is disposed at a position close to the 1 st information processing device 3 that generates the 1 st image. When the images displayed in the enlarged manner on the 1 st and 2 nd display devices 1 and 2 are the 2 nd image, only the 2 nd switching region SR2 provided in the 2 nd display device 2 is reflected in the pointing position PP, and the 2 nd display device 2 is disposed at a position close to the 2 nd information processing device 4 that generates the 2 nd image. This can be controlled in the following manner: in the case where the pointing position PP reaches the 2 nd switching region SR2 in the 1 st display mode, switching from the 1 st display mode to the 2 nd display mode is not performed, and in the case where the pointing position PP reaches the 1 st switching region SR1 in the 2 nd display mode, switching from the 2 nd display mode to the 1 st display mode is not performed.
Accordingly, the user can intuitively grasp whether the image displayed on the 1 st display device 1 and the 2 nd display device 2 is the 1 st image or the 2 nd image (the 1 st display mode) or the 2 nd image (the 2 nd display mode) without displaying on at least one of the 1 st display device 1 and the 2 nd display device 2.
3. Embodiment 3
A display system 10 according to embodiment 3 of the present invention will be described below with reference to fig. 10 to 12. In the display system 10 according to embodiment 2, the switching region SR includes at least one of the 1 st switching region SR1 existing in the 1 st display device 1 and the 2 nd switching region SR2 existing in the 2 nd display device. When the detection unit 44 (detection unit 34) detects that the pointing position PP reaches the 1 st switching region SR1, the display switching unit 43 (display switching unit 33) switches from the 2 nd display mode to the 1 st display mode.
As shown in fig. 10, first, in S1, the 1 st display device 1 and the 2 nd display device 2 constituting the display system 10 enlarge and display the image (the 2 nd image) output from the 2 nd information processing device 4. This corresponds to the 2 nd display mode of fig. 11A.
Next, as shown in fig. 11A, when the operating unit 5 is operated to move the pointing position PP into the 1 st switching region SR1, in S2 of fig. 10, the presence of the pointing position PP in the 1 st switching region SR1 is detected by the detection unit 44. When the pointing position PP is detected by the detection unit 44, in S3, the 2 nd information processing device 4 transmits a switching signal to the 1 st display device 1 and the 2 nd display device 2 so that the 1 st image is displayed in an expanded state (the 1 st display mode) on the 1 st display device 1 and the 2 nd display device 2. Thereby, the display system 10 switches from the 2 nd display mode to the 1 st display mode as shown in fig. 11B. Note that fig. 11B shows a state where the pointing position PP is moved out of the switching region SR in S4. Thereby, the 1 st display mode is continued. The state of fig. 11B is obtained. When the detection unit 44 does not detect the presence of the pointing position PP in the 1 st switching region SR1, it waits until the detection of the presence of the pointing position PP in the 1 st switching region SR 1.
Next, as shown in fig. 12A, when the operating unit 5 is operated to move the pointing position PP into the 2 nd switching region SR2, the presence of the pointing position PP in the 2 nd switching region SR2 is detected by the detector 34 in S4 of fig. 10. When the detection unit 34 detects the pointing position PP, the process returns to S1, and the 1 st information processing device 3 transmits a switching signal to the 1 st display device 1 and the 2 nd display device 2 so that the 2 nd image is displayed in an expanded state (the 2 nd display mode) on the 1 st display device 1 and the 2 nd display device 2. Thereby, the display system 10 is switched from the 1 st display mode to the 2 nd display mode, and the state of fig. 12B is obtained. When the detection unit 34 does not detect the presence of the pointing position PP in the 2 nd switching range SR2, it waits until the presence of the pointing position PP in the 2 nd switching range SR2 is detected.
As described above, in the display system 10 according to embodiment 3, when the pointing position PP reaches the 1 st switching region SR1 in the 2 nd image enlargement display (2 nd display mode) on the 1 st display device 1 and the 2 nd display device 2, the 2 nd display mode is switched to the 1 st display mode. In the 1 st image expansion display (1 st display mode), when the pointing position PP reaches the 2 nd switching region SR2 in the 1 st display device 1 and the 2 nd display device 2, switching from the 1 st display mode to the 2 nd display mode is performed.
In other words, when the images displayed in the 1 st and 2 nd display devices 1 and 2 are the 2 nd image, when the pointing position PP reaches the 1 st switching region SR1 provided in the 1 st display device 1, the 1 st image can be displayed (1 st display mode), and the 1 st display device 1 is disposed at a position close to the 1 st information processing device 3 that generates the 1 st image. When the image displayed in the enlarged manner on the 1 st and 2 nd display devices 1 and 2 is the 1 st image, the 2 nd image can be displayed (2 nd display mode) when the pointing position PP reaches the 2 nd switching region SR2 provided in the 2 nd display device 2, and the 2 nd display device 2 is disposed at a position close to the 2 nd information processing device 4 that generates the 2 nd image. This enables the following control: in the case where the pointing position PP reaches the 1 st switching region SR1 in the 2 nd display mode, switching from the 2 nd display mode to the 1 st display mode is performed, and in the case where the pointing position PP reaches the 2 nd switching region SR2 in the 1 st display mode, switching from the 1 st display mode to the 2 nd display mode is performed.
Accordingly, the user can intuitively grasp whether the image displayed on the 1 st display device 1 and the 2 nd display device 2 is the 1 st image or the 2 nd image (the 1 st display mode) or the 2 nd image (the 2 nd display mode) without displaying on at least one of the 1 st display device 1 and the 2 nd display device 2.
4. Embodiment 4
4-1. Display system 10
Next, a display system 10 according to embodiment 4 of the present invention will be described with reference to fig. 13 and 14. Fig. 13 is a functional block diagram of the display system 10 according to embodiment 4 of the present invention. In embodiment 4, the 1 st display device 1 and the 2 nd display device 2 are provided with a switching signal transmission unit 14 and a switching signal transmission unit 24. The switching signal transmission unit 14 is configured to transmit the switching signal input from the 2 nd information processing device 4 to the 1 st information processing device 3, or to output a signal indicating that the switching signal is output to the 1 st information processing device 3 when the switching signal is input from the 2 nd information processing device 4. The switching signal transmission unit 24 is configured to transmit the switching signal input from the 1 st information processing device 3 to the 2 nd information processing device 4, or to output a signal indicating that the switching signal has been input to the 2 nd information processing device 4 when the switching signal is input from the 1 st information processing device 3.
In the present embodiment, the switching signal communication unit 23 of the 2 nd display device 2 is configured to be able to communicate with the communication unit 31 of the 1 st information processing device 3, but is not able to communicate with the communication unit 41 of the 2 nd information processing device 4. This may be the case, for example, when the switching signal communication unit 23 is a USB port, only 1 USB port is connected to 1 information processing apparatus.
4-2. Flow chart of embodiment 1
Next, processing performed by the display system 10 is described with reference to fig. 14.
First, in S1, the 1 st display device 1 and the 2 nd display device 2 constituting the display system 10 enlarge and display (the 1 st display mode) the image (the 1 st image) output from the 1 st information processing device 3.
Next, when the pointing position PP is moved into the switching region SR by operating the operation unit 5, the presence of the pointing position PP in the switching region SR is detected by the detection unit 34 in S2. When the detection unit 34 detects the pointing position PP, the 1 st switching process is started. If the presence of the pointing position PP in the switching region SR is not detected by the detection unit 34, the process returns to S1.
Next, in S3, the 1 st information processing device 3 transmits a switching signal to the 1 st display device 1 and the 2 nd display device 2. Here, such a switching signal is a signal for switching the image displayed on the 1 st display device 1 or the 2 nd display device 2 to the 2 nd image. Specifically, such a switching signal is a command for instructing the 1 st display device 1 and the 2 nd display device 2 to establish communication with the communication unit 41 of the 2 nd information processing device 4.
In S4, when the 1 st display device 1 and the 2 nd display device 2 receive the switching signal, the 1 st display device 1 and the 2 nd display device 2 enlarge and display (the 2 nd display mode) the 2 nd image output from the 2 nd information processing device 4.
In this way, the switching processing in S3 and S4, that is, the switching processing of switching the images displayed in the enlarged manner on the 1 st display device 1 and the 2 nd display device 2 from the 1 st information processing device 3 to the 2 nd information processing device 4 is the 1 st switching processing. In the present embodiment, in the 1 st switching process, the 1 st information processing device 3 outputs a switching signal to the 1 st display device 1 and the 2 nd display device 2, and the 1 st switching process is executed.
Next, when the pointing position PP is moved into the switching region SR by operating the operation unit 5, the presence of the pointing position PP in the switching region SR is detected by the detection unit 44 in S5. When the detection unit 44 detects the pointing position PP, the execution of the 2 nd switching process is started. If the detection unit 44 does not detect the presence of the pointing position PP in the switching region SR, the process returns to S4.
Next, in S6, the 2 nd information processing device 4 transmits a switching signal to the 1 st display device 1. Here, such a switching signal is a signal for switching the image displayed on the 1 st display device 1 to the 1 st image. At this time, the communication unit 41 of the 2 nd information processing device 4 is not connected to the switching signal communication unit 23 of the 2 nd display device 2, and therefore the switching signal cannot be transmitted from the 2 nd information processing device 4 to the 2 nd display device 2. As a result, the 1 st image is displayed on the 1 st display device 1, and the 2 nd image is displayed on the 2 nd display device 2.
Next, in S7, the 1 st information processing apparatus 3 detects image switching of the 1 st display apparatus 1. In the present embodiment, the 1 st information processing apparatus 3 detects switching of images displayed on the 1 st display apparatus 1 by the video signal communication unit 12 of the 1 st display apparatus 1.
Next, in S8, the 1 st information processing device 3 transmits a switching signal to the 2 nd display device 2. Here, such a switching signal is a signal for switching the image displayed on the 2 nd display device 2 to the 1 st image. In this way, in the present embodiment, when the image displayed on the 1 st display device 1 is switched, the 1 st information processing device 3 outputs the switching signal so that the image (the 1 st image) output from the 1 st information processing device 3 is displayed on the 2 nd display device 2.
Here, instead of the method in S7, the switching signal transmission unit 14 of the 1 st display device 1 may cause the 1 st information processing device 3 to detect the signal output from the 2 nd information processing device 4. Specifically, the switching signal transmission unit 14 of the 1 st display device 1 transmits the switching signal output from the 2 nd information processing device 4 to the 1 st information processing device 3, or outputs a signal indicating that the switching signal has been input to the 1 st information processing device 3 when the switching signal is input from the 2 nd information processing device 4. Further, the 1 st information processing device 3 may be configured to output the switching signal to the 2 nd display device 2 when receiving the signal output from the switching signal transmission unit 14.
In S9, when the 2 nd display device 2 receives the switching signal, the 2 nd display device 2 displays the image (the 1 st image) of the 1 st information processing device 3. Thereby, the 1 st display mode is switched again. In this manner, the switching processing in S6 to S9, that is, the switching processing in which the 2 nd information processing apparatus 4 switches the images displayed in the enlarged manner on the 1 st display apparatus 1 and the 2 nd display apparatus 2 to the 1 st information processing apparatus 3 is the 2 nd switching processing. In the present embodiment, the 2 nd information processing apparatus 4 outputs the switching signal to the 1 st display apparatus 1, and after the 1 st display apparatus 1 receives the switching signal from the 2 nd information processing apparatus 4, the 1 st information processing apparatus 3 outputs the switching signal to the 2 nd display apparatus 2, thereby executing the 2 nd switching processing.
As described above, in the display system 10 according to embodiment 4, the 2 nd information processing device 4 is configured to be able to output a switching signal for switching an image displayed on the 1 st display device 1 to the 1 st display device 1. The 1 st information processing device 3 is configured to be capable of outputting a switching signal for switching an image displayed on the 2 nd display device 2 to the 2 nd display device 2 in accordance with a switching signal. Thus, even when the switching signal communication unit 23 of the 2 nd display device 2 and the communication unit 41 of the 2 nd information processing device 4 cannot communicate the switching signal, the plurality of display devices can be controlled.
As described above, in the display system 10 according to embodiment 4, the switching signal communication unit 13 and the switching signal communication unit 23 of the 1 st display device 1 and the 2 nd display device 2 each have only 1 port, and even when communication is possible only with 1 of the 1 st information processing device 3 and the 2 nd information processing device 4, a plurality of display devices can be controlled.
