Description

The present invention relates to a display switching control device, a display switching control program, a display system, and a display switching control method for projecting an image by a projector.

Whether or not a person can see the image projected by the projector depends on the positional relationship between the projection surface on the projection member and the person. For this reason, there is a display system that uses a projector capable of projecting an image on both sides of the screen as projection planes so that more people can see them (see, for example, Patent Document 1).

JP-A-2018-159886

In the above-mentioned conventional display system, different images can be projected for each projection surface. The projection surface on which the image is projected can be determined by using the detection result of a person. However, even if a different image is projected for each surface, only one surface can be visually recognized by a person.

The desired positional relationship between the projection plane on which the image should be projected and the person may differ depending on the content of the image. For example, when projecting a screen for data input as an image, it is desirable to project the image at a position where a person can look down so that data input can be easily performed. However, the image projected on the projection surface at a position where a person can look down is difficult to see for a person who is not in a nearby position. As described above, the visibility of the image changes depending on the positional relationship between the projection surface and the person, and the desired position of the projection surface also changes depending on the content of the image.

The present invention provides a display switching control device, a display switching control program, a display system, and a display switching control method capable of automatically projecting an image to be projected to a more appropriate position according to a human detection result. The purpose is to provide.

A drive control unit that enables the projector to project an image onto one of the first projection target member and the second projection target member, and a drive control unit based on the detection result indicated by the result data. It includes a first projection target member driven by the driving unit, a switching control unit for switching the projection target including the second projection target member, and switching the image to be projected on the projector.

In the display switching control program according to the present invention, there are at least a first projection target member and a second projection target member as projection targets on which the projector can project an image, and the projector and the first projection target member When there is a drive unit that can change the positional relationship between the two, the drive unit is driven to change the positional relationship with respect to one of the first projection target member and the second projection target member.

Hereinafter, embodiments of a display switching control device, a display switching control program, a display system, and a display switching control method according to the present invention will be described with reference to the drawings.

The display switching control program according to the present invention operates the information processing device as the display switching control device according to the present invention. The display system and the display switching control method according to the present invention are realized by using the display switching control device according to the present invention. For this reason, here, we will basically focus on the display switching control device for explanation. It should be noted that the embodiments including the following modifications are examples, and the present invention is not limited to these embodiments.

Embodiment 1.
FIG. 1 is a diagram showing an example of an input stand to which the display system according to the first embodiment of the present invention is applied.

The input base 10 is roughly classified into a lower portion 11 and an upper portion 12. The lower portion 11 includes a top plate 111 and a shelf 112, and a storage portion exists on the back side of the shelf 112. The display switching control device according to the present embodiment is housed in this storage unit. Two motion sensors 15a and 15b having different ranges for detecting a person are installed on the shelf 112. When it is not necessary to distinguish between them, or when both of them correspond to each other, it is described as "presence sensor 15".

The upper portion 12 is capable of accommodating a projector. The projector is adapted to project an image through an opening 121 provided in the upper portion 12. The projector can project a screen for data input as an image. Data input on the screen is performed using a dedicated electronic pen. The projector analyzes the information transmitted from the electronic pen, identifies the operation content and the operation position performed by the user using the electronic pen, and recognizes the data input by the user. The image projected by the projector is a still image that does not automatically change with the passage of time, or a moving image that automatically changes with the passage of time. An image that changes in response to an operation using an electronic pen is a still image.

FIG. 2 is a diagram showing an example of installation of an input stand to which the display system according to the first embodiment of the present invention is applied, and an example of a range in which two motion sensors can detect a person.

As described above, the projector housed in the input stand 10 is compatible with data input. From this, it is conceivable that the input table 10 is installed for the purpose of accepting, for example, a visitor to a company or the like to input necessary items. In the example shown in FIG. 2, 21 to 23 are walls. Reference numeral 24 denotes a door provided at the entrance, for example, an automatic door. The input base 10 is installed on the entrance side of the wall 23 located at the back when viewed from the entrance. A space for people to pass through is provided on the side of the input base 10 opposite to the wall 22.

In the two motion sensors 15, the range in which a person can be detected, that is, the distance is larger in, for example, the motion sensor 15a. The entire fan-shaped first area 26 is a range in which the motion sensor 15a can detect a person. The second area 27, which is a part of the first area 26, is a range in which the motion sensor 15b can detect a person. The reason why these two motion sensors 15 are installed is that the image to be projected on the projector is switched according to the position where the person is. By switching the image, it is possible to provide desirable information according to the position where the person is. Both the first area 26 and the second area 27 correspond to the assumed range in the present embodiment.

FIG. 3 is a cross-sectional view showing an example of the upper part of the input table. In FIG. 3, the front-back direction and the up-down direction are also shown. Hereinafter, the explanation will be given on the premise of this positional relationship.

As shown in FIG. 3, a space surrounded by plate-shaped members 31 to 34 is formed as a storage portion 35 in the upper portion 12. The projector 30 is stored in the storage unit 35. The opening 121 is formed as a gap between the plate-shaped member 31 and the plate-shaped member 32. The projected light L emitted by the projection unit 30a of the projector 30 for projecting an image passes through the opening 121.

On the rear side of the plate-shaped member 31, there is a plate-shaped member 36 having transparency. As shown in FIG. 3, the plate-shaped member 36 is movable in the vertical direction by the drive unit 37. The movement changes the positional relationship between the plate-shaped member 36 and the projector 30. When the plate-shaped member 36 is moved to the position of the opening 121, the projected light L is projected on the rear side of the plate-shaped member 36, and the image can be visually recognized from the front side of the plate-shaped member 36. When the plate-shaped member 36 is retracted from the opening 121, the projected light L is projected onto the upper surface of the top plate 111. Therefore, in the present embodiment, the plate-shaped member 36 corresponds to the first projection target member, and the top plate 111 corresponds to the second projection target member.

As the plate-shaped member 36 to which the projected light L is projected, a member having non-transparent transparency can be widely adopted. As the member, for example, an acrylic plate can be mentioned. In order to distinguish it from the plate-shaped members 31 to 34, the plate-shaped member 36 will be hereinafter referred to as an acrylic plate 36.

The drive unit 37 includes at least a power source capable of moving the acrylic plate 36 up and down. A guide mechanism for the acrylic plate 36 is provided on the upper portion 12 so that the acrylic plate 36 can be appropriately moved up and down and its position can be stably maintained. A guide member such as a rail corresponds to an example of a guide mechanism. In FIG. 3, such a guide mechanism, a transmission mechanism for transmitting power from the drive unit 37 to the acrylic plate 36, and the like are omitted.

The upper surface of the top plate 111 exists at a position where a person looks down. For this reason, the image projected on the upper surface of the top plate 111 is a screen for data input. By projecting such a screen onto the upper surface of the top plate 111, the visitor can easily input data. This screen will be referred to as the "input screen" hereafter.

FIG. 4 is a diagram illustrating an example of a screen for data input. Here, an example of an input screen will be specifically described with reference to FIG.

The input screen 40 showing an example in FIG. 4 is for name input. A data input area 41 is provided on the input screen 40, and a plurality of input item selection buttons 42 are arranged on the side of the data input area 41. A "done" button 43 and a "cancel" button 44 are arranged above the data input area 41. Here, "40" is used as a code for all input screens.

By operating the input item selection button 42 with an electronic pen, the visitor can display the input screen 40 corresponding to the operated input item selection button 42. The check box 42a provided on each input item selection button 42 visually indicates the type of the displayed input screen 40, in other words, the items that can be input.

In the data input area 41, an input item display area 411, an input result display area 412, a plurality of data writing areas 413, a "yes" button 414, and a "one character erase" button 415 are arranged. In the input item display area 411, a "stop input" button 411a is arranged.

The data writing area 413 is an area for inputting data by handwriting, and there are a plurality of data writing areas 413 for each of the surname and the given name. The data handwritten in the data writing area 413, that is, the characters including alphanumeric characters are analyzed and recognized by the projector 30, and the recognition result is displayed in the input result display area 412. The “Yes” button 414 is a button to be operated at the end of input. By operating the "Yes" button 414, the recognition result displayed in the input result display area 412 is confirmed as the input data. The "Erase one character" button 415 is a button for instructing the erasure of the last character displayed in the input result display area 412. The "stop input" button 411a is a button for instructing the stop of data input. When this button 411a is operated, all the characters displayed in the input result display area 412, that is, all the recognition results are invalid.

The "done" button 43 is a button for instructing the completion of data input. When the "done" button 43 is operated, the data input is completed. The "cancel" button 44 is a button for instructing the cancellation of data input. By operating the "Cancel" button 44, all the input data is discarded.

Basically, only visitors who have not input data are requested to input data on the input screen 40 or the like. However, data input is impossible for a person who cannot touch the upper surface of the top plate 111. The image projected on the upper surface of the top plate 111 can only be visually recognized by a person who is near the top plate 111, or even if it is not impossible, it is difficult to visually recognize the image. Therefore, in the present embodiment, assuming a visitor who is not in the second area 27 and needs to input data, an image for guiding the data input is projected on the acrylic plate 36. There is.

5 and 6 are diagrams showing an example of an image projected on an acrylic plate. More specifically, FIG. 5 is a diagram showing an example of an image projected onto an acrylic plate to guide a visitor for data entry. FIG. 6 is a diagram showing an example of an image projected on an acrylic plate in order to inform the visitor that the input screen is displayed. Both FIGS. 5 and 6 show an example of an image projected on the acrylic plate 36 from the viewpoint from the front side.

The surface of the acrylic plate 36 installed on the input table 10 faces the visitor who entered from the entrance. As shown in FIG. 3, the acrylic plate 36 is installed on the front side of the upper portion 12. As shown in FIGS. 1 to 3, the input table 10 has an entrance side on the front side. Therefore, assuming visual recognition from the front surface, the image projected on the projection surface, which is the rear surface, is easy to be visually recognized even by a visitor entering from the entrance. For this reason, in the present embodiment, the acrylic plate 36 is used to provide information to a person who is relatively far from the input table 10. When a message as shown in FIG. 5 is projected on the acrylic plate 36 as an image, a visitor who enters from the entrance can be appropriately guided to the input table 10 with a very high probability.

The input table 10 is basically installed on the assumption that data is input by a visitor. However, the person who enters from the entrance is not always the visitor. For some reason, a non-visitor may approach the input table 10. It is also conceivable that a visitor who enters from the entrance and moves into the first area 26 may move out of the first area 26. For this reason, a person who may visually recognize the projected image is hereinafter collectively referred to as an "assumed person".

It is conceivable that the message as shown in FIG. 5 is displayed only when there is no expected person in the second area 27. However, it is also conceivable to display when the situation changes from the situation where the assumed person is not present in the first area 26 to the situation where the assumed person is present in the first area 26. In this case, the image projected on the acrylic plate 36 is in a situation where there is no expected person in the first area 26, a situation where there is an assumed person in the first area 26 excluding the second area 27, and in the second area 27. Images can be switched according to the situation in which the supposed person is present.

In this way, in the present embodiment, the projection target for projecting the image is selected from the acrylic plate 36 and the top plate 111 according to the detection result of the assumed person by the two motion sensors 15, and the projection is performed. The image to be displayed is automatically switched. When the selection of the projection target is changed, that is, when the projection target is switched, the image is also switched. Therefore, the acrylic plate 36 is moved as needed. By selecting the projection target in this way, even if the projector 30 can project an image in one direction, the image to be projected is automatically placed at a position that is easy for the person to see according to the position where the person is. Can be projected.

The projector 30 is basically for data input. By adding the acrylic plate 36 to an object on which such a projector 30 can project an image, the projector 30 can be used for a wider range of purposes. Compared with the case where a plurality of projectors 30 are prepared, the cost can be greatly suppressed. Further, since the object on which the image is projected is switched by the movement of the acrylic plate 36, a large space for projecting the image is unnecessary. In this embodiment, it is also possible to use the existing input stand 10. Therefore, there are advantages in terms of cost and installation.

In the present embodiment, two motion sensors 15 are used, but one motion sensor 15 may be used. Even if there is only one motion sensor 15, two messages as shown in FIGS. 5 and 6 can be projected on the acrylic plate 36. Further, the detection sensor that detects the supposed person is not limited to the motion sensor 15. The detection sensor may be capable of measuring the distance to the intended person. Alternatively, the function of the detection sensor is to take a picture of the surrounding area including the input stand 10 and analyze the image obtained by the taking picture to specify the presence or absence of the supposed person and the distance between the input stand 10 and the supposed person. It may be realized with. For this reason, the detection sensor may include an information processing device. Therefore, the result data output by the detection sensor, more specifically, the format of the result data, the content indicated by the result data, and the like are not particularly limited.

FIG. 7 is a diagram showing a configuration example of a display system according to the first embodiment of the present invention and a functional configuration example of a display switching control device included in the display system. Next, with reference to FIG. 7, the display system and the display switching control device 70 included therein will be specifically described. As described above, this display system is applied to the input base 10, and all the components are provided in the input base 10. The display switching control device 70 corresponds to the display switching control device in the present embodiment, and is housed in, for example, the lower portion 11 of the input base 10.

As shown in FIG. 7, the display system according to the present embodiment includes two motion sensors 15, a projector 30, a drive unit 37, a display switching control device 70, and an electronic pen 80. As described above, the electronic pen 80 is a device for inputting data on the input screen 40 projected on the upper surface of the top plate 111. The electronic pen 80 wirelessly communicates with the projector 30.

The display switching control device 70 is, for example, one information processing device, and is housed in the lower portion 11 of the input stand 10. Therefore, all the components of the display system are present in the input table 10. That is, the display system is realized only by the input stand 10.

As described above, the electronic pen 80 has a function of wirelessly communicating with the projector 30. Further, the projector 30 has a function of specifying the position pointed to by the electronic pen 80. With this function, when projecting an image to be operated such as the input screen 40, the projector 30 communicates with the electronic pen 80 to specify the position pointed to by the electronic pen 80 on the projected image. Therefore, when the supposed person operates the projection screen on the input screen 40 by using the electronic pen 80, the projector 30 can specify the position operated by the assumed person and the operation content thereof. Therefore, the supposed person can input data on the input screen 40 by using the electronic pen 80.

As shown in FIG. 7, the display switching control device 70 includes an input unit 71, a switching control unit 72, an image storage unit 73, a display control unit 74, and a drive control unit 75 as functional configurations.

The input unit 71 is connected to two motion sensors 15. As a result, each of the two motion sensors 15 outputs data indicating the detection result of the supposed person to the input unit 71. The data showing the detection result of the supposed person corresponds to the result data in the present embodiment.

The switching control unit 72 inputs the result data from the input unit 71 and processes it, and controls the display control unit 74 and the drive control unit 75 according to the processing result. The display control unit 74 specifies an image to be projected on the projector 30 according to the instruction of the switching control unit 72. Therefore, the switching control unit 72 can switch the image to be projected on the projector 30 via the display control unit 74. The function of the switching control unit 72 corresponds to the switching control function in the present embodiment. As described above, the result data is not particularly limited.

The image data for projecting the image on the projector 30 is stored in the image storage unit 73. Therefore, the display control unit 74 reads out the image data stored in the image storage unit 73 and outputs the image data to the projector 30 as needed. The image data stored in the image storage unit 73 includes image display data 731 that is not intended for visitors, message display data 732 as shown in FIG. 5, and message display as shown in FIG. There are data 733 for, and data group 734 for displaying various input screens 40. Hereinafter, the data 731 will be referred to as "general display data 731", the data 732 will be referred to as "input guidance display data 732", the data 733 will be referred to as "switching guidance display data 733", and the data group 734 will be referred to as "input screen data group 734".

As described above, the projector 30 can specify the operation position and the operation content by the electronic pen 80. These specific results are notified to the display control unit 74 as operation information, and further notified to the switching control unit 72 via the display control unit 74. As a result, the switching control unit 72 performs analysis using the operation information notified from the projector 30, identifies the operation content by the electronic pen 80 on the input screen 40 during projection, and gives an instruction according to the specific result. Is performed on the display control unit 74.

The identification of the operation content here includes the handwritten position, the recognition of the handwritten input character, and the like. Therefore, the switching control unit 72 instructs the display control unit 74 to operate the input screen data to be output to the projector 30 as necessary. The display control unit 74 newly outputs the input screen data after the operation to the projector 30. As a result, the input screen 40 projected by the projector 30 changes according to the operation by the electronic pen 80. The display of the handwritten character in the data writing area 413, the display of the recognition result of the character in the input result display area 412, etc. are performed by operating the input screen data and displaying the input screen data after the operation on the projector 30. Realized by the output.

The drive control unit 75 controls the drive unit 37. Therefore, the switching control unit 72 controls the drive of the drive unit 37 via the drive control unit 75. By controlling the drive of the drive unit 37, the switching control unit 72 can switch the object on which the image is projected on the projector 30 between the acrylic plate 36 and the top plate 111. The function of the drive control unit 75 corresponds to the drive control function in the present embodiment.

FIG. 11 is a diagram showing a hardware configuration example of an information processing device that can be used as the display switching control device according to the first embodiment of the present invention. Here, with reference to FIG. 11, a hardware configuration example of an information processing device that can be used as the display switching control device 70 will be specifically described. In FIG. 11, since the information processing device can be used as the display switching control device 70, “70” is added as a reference numeral. Therefore, here, the information processing device is hereinafter referred to as "information processing device 70".

As shown in FIG. 11, the information processing device 70 includes a processor 701, a memory 702, a NIC (Network Interface Card) 703, an I / F (InterFace) controller group 704, and a graphic controller 705 as hardware configurations. This hardware configuration is an example, and the hardware configuration of the information processing apparatus 70 is not limited to that shown in FIG.

The memory 702 is a component corresponding to the image storage unit 73, and includes, for example, an auxiliary storage device such as a hard disk device and an SSD in addition to a RAM (Random Access Memory). The display switching control program 702a, which is a program for realizing the display switching control device 70 on the information processing device 70, is stored in the memory 702. That is, when the processor 701 executes the display switching control program 702a, the information processing device 70 operates as the display switching control device 70.

NIC703 is a component that performs communication via a network. Various image data to be stored in the image storage unit 73 can be acquired from an external device connected to the network by the NIC703. The data received by the NIC 703 is stored in the memory 702 by the processing of the processor 701.

Each I / F controller constituting the I / F controller group 704 realizes communication with a peripheral device connectable to the information processing device 70. The two motion sensors 15, the projector 30, and the drive unit 37 all correspond to peripheral devices. Other peripheral devices include, for example, keyboards, pointing devices, printers, and the like. When controlling via the I / F controller, the drive unit 37 includes, in addition to a power source such as a motor, a drive circuit for driving the power source, a communication circuit that enables communication with the I / F controller, and a communication circuit. The configuration includes a control circuit that controls the drive circuit according to an instruction received by the communication circuit.

The medium drive device 710 shown in FIG. 11 is also included in the peripheral device. The medium drive device 710 is a device for accessing the mounted or detachable recording medium 711. The display switching control program 702a can be stored in the recording medium 711 and loaded from the medium drive device 710 into the information processing device 70. The display switching control program 702a may be caused to be transmitted to the information processing device 70 via the network. Therefore, the recording medium for recording the display switching control program 702a is not limited to the memory 702 and the recording medium 711. That is, the recording medium may be a recording medium that can be accessed by another external device capable of communicating via a network or the like.

The graphic controller 705 can output the image data instructed by the processor 701 to the display device connected to the information processing device 70. Therefore, the processor 701 can switch the image to be displayed on the display device connected to the information processing device 70 by the graphic controller 705.

When the display switching control device has the hardware configuration shown in FIG. 11, one or more I / F controllers constituting the I / F controller group 704 function as the input unit 71. The switching control unit 72, the display control unit 74, and the drive control unit 75 are all realized by the processor 701 executing the display switching control program 702a. Since the switching control unit 72 does not directly control the peripheral device, the hardware resources to be realized are realized by the hardware resources including the processor 701 and the memory 702. When the switching control unit 72 includes a function for performing data communication, the hardware resource also includes NIC703. The hardware resources for realizing the display control unit 74 and the drive control unit 75 include, for example, one I / F controller in addition to the processor 701 and the memory 702.

8 to 10 are flowcharts showing an example of display switching control processing. This display switching control process is a process realized by the processor 701 executing the display switching control program 702a stored in the memory 702. Next, the display switching control process will be described in detail with reference to FIGS. 8 to 10. It is the processor 701 that executes the display switching control program 702a. For this reason, here, the processor 701 is the main body that executes the process, and the description will be given.

First, in step S11, the processor 701 selects general display data 731 as data to be displayed as an image on the projector 30. In the following step S12, the processor 701 causes the projector 30 to output the selected general display data 731 via the corresponding I / F controller, and causes the projector 30 to project an image using the general display data 731. After that, the process proceeds to step S13.

In step S13, the processor 701 refers to the result data input from the motion sensor 15 and determines whether or not there is an assumed person in the first area 26. When the result data indicating that the assumed person is in the first area 26 is obtained, the determination in step S13 becomes YES and the process proceeds to step S19. If such result data cannot be obtained, the determination in step S13 becomes NO, and the process proceeds to step S14.

The case where the assumed person is in the first area 26 is the case where the assumed person who was outside the first area 26 moves into the first area 26, that is, from the state where the motion sensor 15a does not detect the assumed person. A case where the state has changed to detect the supposed person, a case where the assumed person who was in the second area 27 moves into the first area 26 outside the second area 27, that is, two motion sensors 15 both detect the assumed person. There are two cases in which the motion sensor 15a changes from the detected state to the state in which only the human sensor 15a detects the supposed person. The supposed person who has moved out of the second area 27 may be inputting data. The move out of the second area 27 during data entry may be temporary for some reason. For this reason, in the present embodiment, the temporary movement of the assumed person during data input is supported. In the present embodiment, when the data input on the input screen 40 exists, it is assumed that the data is being input.

In the present embodiment, the assumed person who has moved out of the first area 26 considers that he / she has no intention of continuing the data input, and unconditionally discards the input data. The assumed person who has moved into the first area 26 outside the second area 27 can continue the data input on condition that he / she returns to the second area 27 within the set time. The presumed person who stays in the second area 27 considers that he / she intends to continue the data input, and tries to maintain the state in which the data input is possible.

Therefore, in the present embodiment, the following control is performed depending on the case.
(1) Data entry → The assumed person moves into the first area 26 outside the second area 27 → Starts timing → The assumed person moves outside the first area 26 → Forcibly terminates the data input and discards the data , The acrylic plate 36 is lowered to display the general display data 731. (2) Data is being input → The assumed person moves into the first area 26 outside the second area 27 → Starts timing → Times out in that state → Discards the data, Input guidance Display data 732 (Fig. 5) is displayed (3) Data is being input → The assumed person moves into the first area 26 outside the second area 27 → Starts timing → The assumed person is in the second area 27 before the timeout Move → Ends time counting and maintains the state where data can be entered. Forcible termination of data entry is hereinafter referred to as "cancellation of data entry" in order to clarify the distinction from the normal termination of data entry.

Returning to the description of FIG. In step S14, in which the determination in step S13 becomes NO, the processor 701 determines whether or not the state in which the presumer is detected only in the first area 26 has changed to the state in which the presumer is not detected. If the presumed person in the first area 26 is moved out of the first area 26 and the presumed person in the first area 26 is no longer detected, the determination in step S14 becomes YES and the process proceeds to step S15. To do. If this is not the case, that is, if the state in which there is no expected person in the first area 26 continues, the determination in step S14 becomes NO and the process returns to step S12. As a result, the projector 30 continues to project the image based on the general display data 731.

In step S15, the processor 701 determines whether or not data is being input. During data input, the projector 30 projects one of the input screens 40. Therefore, when the input screen 40 is projected onto the projector 30, the determination in step S15 becomes YES, and the process proceeds to step S16. When the input screen 40 is not projected on the projector 30, the determination in step S15 becomes NO, and the process proceeds to step S18.

In step S16, processor 701 discards the input data. In the following step S17, the processor 701 controls the drive unit 37 via the corresponding I / F controller to lower the acrylic plate 36. In the next step S18, the processor 701 selects the general display data 731 as the image data to be displayed on the projector 30. After that, the process returns to step S12.

As described above, the data input on the input screen 40 is recognized and saved on the display switching control device 70 side. The storage destination of this data is, for example, a work area reserved on the memory 702. The data stored in this area will be erased by discarding.

In step S19, in which the determination in step S13 is YES and the transition is made, the processor 701 determines whether or not a supposed person has been detected in the second area 27. If both of the two motion sensors 15b have detected the supposed person, the determination in step S19 becomes YES and the process proceeds to step S20. When only the motion sensor 15b does not detect the supposed person, that is, when the assumed person is detected only in the first area 26 outside the second area 27, the determination in step S19 becomes NO and the step in FIG. 10 Move to S51.

In step S20, the processor 701 determines whether or not a supposed person in the second area 27 is newly detected. When the detection result by the motion sensor 15b changes from undetected to detected, the determination in step S20 becomes YES and the process proceeds to step S21. If the detection result by the motion sensor 15b maintains the detection state, that is, if the assumed person in the second area 27 has not moved, the determination in step S20 becomes NO and the process proceeds to step S31 in FIG. To do.

In step S21, the processor 701 determines whether or not the time is being clocked. If the time is being clocked, the determination in step S21 becomes YES and the process proceeds to step S22. If the time is not timed, the determination in step S21 becomes NO and the process proceeds to step S23. The time can be measured by using the hard timer mounted on the processor 701.

In step S23, since the supposed person has moved into the second area 27, the processor 701 newly projects an image using the switching guidance display data 733 (see FIG. 6) on the projector 30. In the following step S24, the processor 701 controls the drive unit 37 to raise the acrylic plate 36 and retract the acrylic plate 36 from the opening 121. In the next step S25, the processor 701 causes the projector 30 to project the initial input screen 40, which is one of the input screens 40 prepared for each input item. The initial input screen 40 is projected on the upper surface of the top plate 111. After that, the process returns to step S12.

The determination in step S20 is NO in the situation where the input screen 40 is projected on the projector 30. Therefore, in steps S31 to S37 of FIG. 9, a process for dealing with the situation is executed.

As described above, the projector 30 projecting the input screen 40 outputs the position where the operation was performed using the electronic pen 80 and the operation information indicating the operation content to the display switching control device 70 at any time. The processor 701 identifies the operation performed on the input screen 40 by the analysis using the operation information. According to the specific result, the data input by the supposed person is recognized as necessary, and the display contents of the input screen 40 are updated or the input screen 40 is switched as necessary. All of these are realized by executing the processes of steps S31 to S37 of FIG.

First, in step S31, the processor 701 determines whether or not there has been an operation on the input screen 40. If any operation is detected by the analysis using the operation information, the determination in step S31 becomes YES and the process proceeds to step S32. If no operation is detected, the determination in step S31 becomes NO, and the process returns to step S12 in FIG. As a result, the projector 30 continuously projects the input screen 40 having the same contents.

In step S32, the processor 701 determines whether or not an end operation, that is, an operation to the "done" button 43 or the "cancel" button 44 is detected. If the operations on the two buttons 43 and 44 are not detected, that is, if the expected person performs handwriting input or an operation on another button, the determination in step S32 becomes NO and step S33. Move to. When an operation to any of the two buttons 43 and 44 is detected, the determination in step S32 becomes YES and the process proceeds to step S34.

In step S33, the processor 701 executes a process according to the detected operation. After that, the process returns to step S12 of FIG. By the process performed in step S33, the update of the input screen 40 including the character recognition corresponding to the handwriting input, the switching of the input screen 40 to be projected, and the like are realized.

In step S34, the processor 701 determines whether or not an operation on the "done" button 43 has been detected. When the "completion" button 43 is operated by the assumed person, the determination in step S34 becomes YES, and the process proceeds to step S36. When the assumed person operates the "Cancel" button 44 instead of the "Done" button 43, the determination in step S34 becomes NO and the process proceeds to step S35.

In step S35, the processor 701 discards, that is, erases the data recognized while projecting the input screen 40 onto the projector 30, and newly projects the initial input screen onto the projector 30. In that way, after preparing for data input next, the process returns to step S12 of FIG.

In step S36, the processor 701 transmits the recognized and saved data to another information processing device as the data input by the supposed person. In the following step S37, the processor 701 newly projects the initial input screen onto the projector 30. In that way, after preparing for data input next, the process returns to step S12 of FIG.

The data transmission in step S36 is performed using, for example, NIC703. By this data transmission, the data is provided to the department that should deal with the visitor, for example, the reception desk or / and the department to be visited. As a result, the visitor can smoothly move to the visited destination after inputting the data.

Step S51 of FIG. 10 shifts to the case where the assumed person exists only in the first area 26 outside the second area 27. In step S51, the processor 701 determines whether or not the motion sensor 15a has newly detected the supposed person. When the assumed person moves from outside the first area 26 to inside the first area 26, the detection result of the assumed person by the motion sensor 15a changes from undetected to detected. Therefore, the determination in step S51 becomes YES, and the process proceeds to step S52. If this is not the case, that is, the presumed person in the first area 26 outside the second area 27 keeps the state, or the presumed person in the second area 27 is in the first area 26 outside the second area 27. When moving in, the determination in step S51 becomes NO, and the process proceeds to step S53.

In step S52, the processor 701 changes the data to be used by the projector 30 for projecting an image from the general display data 731 to the input guidance display data 732 (see FIG. 5). After that, the process returns to step S12 of FIG.

In step S53, the processor 701 determines whether or not the detection result by the motion sensor 15b has changed from detected to undetected. As described above, the change occurs when the assumed person who was in the second area 27 moves into the first area 26 outside the second area 27. Therefore, when such a movement is performed by the assumed person, the determination in step S53 becomes YES, and the process proceeds to step S54. If this is not the case, that is, if the supposed person in the first area 26 outside the second area 27 maintains that state, the determination in step S53 becomes NO and the process proceeds to step S58.

In step S54, the processor 701 determines whether or not data is being input. When the assumed person who has moved from the inside of the second area 27 to the inside of the first area 26 outside the second area 27 is inputting some data, the determination in step S54 becomes YES and the process proceeds to step S55, and the processor 701 moves to step S55. , Start timing. After that, the process proceeds to step S12 of FIG. If the assumed person who has moved from the inside of the second area 27 to the inside of the first area 26 outside the second area 27 has not input data, the determination in step S54 becomes NO and the process proceeds to step S56.

In step S56, the processor 701 controls the drive unit 37 via the corresponding I / F controller to lower the acrylic plate 36 to the position of the opening 121. In the following step S57, the processor 701 selects the input guidance display data 732 (see FIG. 5) as the data to be used by the projector 30 for projecting the image. After that, the process returns to step S12 of FIG.

In step S58, in which the determination in step S53 becomes NO and the transition proceeds, the processor 701 determines whether or not data is being input. If the presumed person who remains in the first area 26 outside the second area 27 has input some data, the determination in step S58 becomes YES and the process proceeds to step S59. If the assumed person has not input data, the determination in step S58 is NO, and the process returns to step S12 in FIG. If the determination in step S58 is YES, the process in step S55 is executed before that, and the time is being clocked.

In step S59, the processor 701 determines whether or not it has timed out. If the set time has elapsed since the time counting was started in step S55, the time-out is assumed and the determination in step S59 is YES. As a result, the process proceeds to step S60, and the processor 701 discards the input data. After the disposal, the process proceeds to step S56. As a result, after discarding the data, the projector 30 starts projecting the image by the input guidance display data 732. On the other hand, if the time-out has not occurred, the determination in step S59 is NO, and the process returns to step S12 in FIG.

In the present embodiment, the image is not projected by the input guidance display data 732 immediately after the data input is completed. This is because it takes a relatively long time to move the acrylic plate 36. That is, after the data entry is completed, it takes a long time for another assumption person in the second area 27 or an assumption person who moves immediately into the second area 27 to be able to input data. This is to suppress. In this way, when the projection of the input screen 40 is prioritized, a comfortable usage environment is realized especially in a situation where there are a plurality of presumers who should input data.

A time-out prospective person in the first area 26 outside the second area 27 may take different actions if there is another prospective person who may enter data within the visible range. It is considered expensive. That is, it is considered that there is a high probability that the data input will be completed by operating the "Cancel" button 44 in consideration of the possibility that another assumption person will input the data. For this reason, after canceling the data input, it is considered that there is no other presumed person who may input the data nearby, and the image is immediately projected by the input guidance display data 732. .. By projecting the image by the input guidance display data 732 in this way, it can be expected that the information can be more reliably provided by the projection of the image to the presumed person who needs the projection of the image.

In the present embodiment, the acrylic plate 36 is the only member that changes the positional relationship with the projector 30, but the number of the members may be plural. The farther away from the projector 30, the larger the image can be projected. From this, as a member whose positional relationship can be changed, for example, a plurality of members having different distances from the projector 30 are arranged, and an image, that is, is used according to the detected distance between the supposed person and the projector 30. The member for projecting the projected light L may be switched. When the member on which the projected light L is projected is switched in this way, it is possible to project an image having a size that is easy for the intended person to see.

The surface of the member on which the projected light L is projected, that is, the projection surface does not have to be flat. For example, the projection surface may be curved. The shape of the projection surface of each member does not have to match. When the projector 30 capable of projecting the projected light L in a plurality of different directions is used, even if one or more members whose positional relationship can be changed are arranged in two or more directions in which the projected light L can be projected. good. When a plurality of different directions are two directions, one or more members whose positional relationship can be changed are arranged in only one direction, and the other one direction is the detection result of the supposed person or with the assumed person. Whether or not to project the projected light L may be determined based on the distance between them. The change in the positional relationship between the member and the projector 30 may be realized by moving the projector 30.
