Description

This disclosure relates to an image display program and an image display device.

Technology is known for displaying images on multiple image display screens. For example, Patent Document 1 discloses a technology for generating a simulation image showing how content will be played back when it is screened on multiple image display screens in a multi-screen theater.

Special Publication No. 2016-536909

In the above-mentioned technologies, the visual information that can be provided to a user viewing an image display surface tends to be limited to pre-prepared content. For this reason, in this technical field, it is desirable to be able to provide visual information to users in a more diverse manner.

The image display program and image display device disclosed herein aim to increase the freedom of how visual information is provided to the user.

An image display program (P) according to one aspect of the present disclosure causes a computer (C) to function as a background image display unit (10) capable of displaying a background image (D1) on each of a plurality of image display surfaces (S), and a superimposed image display unit (11) capable of displaying a superimposed image (D2) on at least one of the plurality of image display surfaces (S) by superimposing the superimposed image (D1) displayed on the image display surface (S).

An image display device (1) according to one embodiment of the present disclosure includes a background image display unit (10) capable of displaying a background image (D1) on each of a plurality of image display surfaces (S), and a superimposed image display unit (11) capable of displaying a superimposed image (D2) on at least one of the plurality of image display surfaces (S) by superimposing the superimposed image (D1) displayed on the image display surface (S).

At least one of these image display programs (P) and image display devices (1) can display not only a background image (D1) on each of a plurality of image display surfaces (S), but also a superimposed image (D2) on the background image (D1) on at least one of the image display surfaces (S). This makes it possible to increase the degree of freedom in the manner in which visual information is provided to the user.

An image display program (P) according to one aspect of the present disclosure may cause a computer (C) to function as a layout setting unit (12) that sets a layout for displaying a background image (D1) and a superimposed image (D2) on an image display surface (S). This makes it possible to set a desired layout for displaying a background image (D1) and a superimposed image (D2) on an image display surface (S). This makes it possible to further increase the degree of freedom in the manner in which visual information is provided to a user.

The image display program (P) according to one aspect of the present disclosure may cause the computer (C) to function as a preview image display unit (13) that displays a preview image showing a state in which the background image (D1) and the superimposed image (D2) are displayed based on the layout set by the layout setting unit (12). This makes it possible to visually confirm in advance the layout in which the background image (D1) and the superimposed image (D2) are displayed on the image display surface (S).

In an image display program (P) according to one aspect of the present disclosure, the layout may be a dynamic layout in which the manner in which the background image (D1) and the superimposed image (D2) are displayed changes over time. This allows for even greater freedom in the manner in which visual information is provided to the user.

The image display program (P) according to one aspect of the present disclosure may cause the computer (C) to function as a stimulus generating unit (14) that generates a stimulus corresponding to the background image (D1) or the superimposed image (D2) displayed on the image display surface (S). This allows information to be provided to the user through various stimuli in addition to the background image (D1) and the superimposed image (D2). This makes it possible to further increase the degree of freedom in the manner in which information is provided to the user, including manners other than visual manners.

The image display program (P) according to one embodiment of the present disclosure may cause the computer (C) to function as a stimulus setting unit (15) that sets the content of the stimulus generated by the stimulus generating unit (14). This makes it possible to set the content of the stimulus to be generated to a desired content. This makes it possible to further increase the degree of freedom in the manner in which information is provided to the user.

In the image display program (P) according to one aspect of the present disclosure, when a background image (D1) is displayed on each of the multiple image display surfaces (S) by the background image display section (10), the stimulus setting section (15) may set a stimulus having different contents when the superimposed image (D2) is displayed on at least one of the multiple image display surfaces (S) by the superimposed image display section (11) and when the superimposed image (D2) is not displayed on any of the multiple image display surfaces (S) by the superimposed image display section (11). This allows a stimulus having different contents to be generated depending on whether or not the superimposed image (D2) is displayed on at least one of the multiple image display surfaces (S), thereby making it possible to further increase the degree of freedom in the manner in which information is provided to the user.

The image display program (P) according to one aspect of the present disclosure may cause the computer (C) to function as an image display surface change unit (16) that changes the image display surface (S) on which the superimposed image (D2) is displayed by the superimposed image display unit (11) to another image display surface (S). This makes it possible, for example, to move the superimposed image (D2) to an image display surface (S) that is easily visible to the user, or to move the superimposed image (D2) to an image display surface (S) that is not easily visible to the user. This makes it possible to provide visual information to the user in a desired manner.

An image display program (P) according to one aspect of the present disclosure may cause a computer (C) to function as a background image suggestion unit (17) that suggests a background image (D1) to be displayed on each of a plurality of image display surfaces (S) by a background image display unit (10). This makes it possible to suggest a suitable background image (D1) to a user. This also reduces the effort required for a user to select a background image (D1) by himself/herself, thereby improving convenience.

In an image display program (P) according to one aspect of the present disclosure, the background image suggestion unit (17) may suggest a background image (D1) to be displayed on each of the multiple image display surfaces (S) by the background image display unit (10) based on a superimposed image (D2) displayed on at least one of the multiple image display surfaces (S) by the superimposed image display unit (11). This makes it possible to suggest to the user a background image (D1) that matches the displayed superimposed image (D2).

An image display program (P) according to one aspect of the present disclosure causes a computer (C) to function as an event input receiving unit (18) that receives input of an event performed by a user, and a background image suggestion unit (17) may suggest a background image (D1) to be displayed on each of a plurality of image display surfaces (S) by a background image display unit (10) based on the event input received by the event input receiving unit (18). This makes it possible to suggest to the user a background image (D1) that matches an event performed by the user.

Note that the reference numerals in parentheses above are intended to indicate the reference numerals of components in the embodiments described below as an example of the present disclosure, and are not intended to limit the present disclosure to the aspects of the embodiments.

In this way, the image display program and image display device disclosed herein can increase the freedom of how visual information is provided to the user.

FIG. 1 is a block diagram showing an image display device realized by executing an image display program according to this embodiment. FIG. 2 is a diagram showing an example of a state in which background images and superimposed images are displayed on a plurality of image display surfaces. FIG. 3 is a block diagram showing the image display program.

Below, exemplary embodiments will be described with reference to the drawings. Note that the same or equivalent parts in each drawing are given the same reference numerals, and duplicate explanations will be omitted.

[Overall configuration]
Fig. 1 is a block diagram showing an image display device 1 realized by executing an image display program P according to this embodiment. Fig. 2 is a diagram showing an example of a state in which a background image D1 and a superimposed image D2 are displayed on a plurality of image display surfaces S. As shown in Figs. 1 and 2, the image display device 1 is a device realized by executing the image display program P by a computer C, and displays a predetermined image on each of the plurality of image display surfaces S. More specifically, the image display device 1 is capable of displaying a background image D1 and a superimposed image D2 on the image display surfaces S as the predetermined images.

Here, the "background image" is an image displayed on the image display surface S as the background of the superimposed image D2. The background image D1 may be displayed more widely than the superimposed image D2 on each image display surface S, and in particular may be displayed over the entire surface of each image display surface S. The background image D1 can be displayed on multiple image display surfaces S. Note that the background image D1 may actually be displayed on each of the multiple image display surfaces S, or may actually be displayed only on some of the image display surfaces S (for example, one image display surface S) among the multiple image display surfaces S. The background image D1 may be a natural landscape such as a forest, grassland, sea, mountain, etc., a design created by a user, etc., or a single color. The background image D1 may also be a still image such as a photograph, or a video.

The "superimposed image" is an image that is superimposed on the background image D1. The superimposed image D2 may be displayed narrower than the superimposed image D2 on each image display surface S, and may be displayed so as to fit on the background image D1 (i.e., not to extend beyond the background image D1). The superimposed image D2 can be displayed on multiple image display surfaces S. Note that the superimposed image D2 may actually be displayed on each of the multiple image display surfaces S, or may actually be displayed only on some of the image display surfaces S (for example, one image display surface S) among the multiple image display surfaces S. The superimposed image D2 may include information such as a message or comment intended to be known by the user, etc. The superimposed image D2 may be an image (opaque image) that is superimposed on the background image D1 so that the area of the background image D1 that overlaps with the superimposed image D2 is not visible through the image (opaque image). Alternatively, the superimposed image D2 may be an image (semi-transparent image) that is displayed superimposed on the background image D1 so that the area of the background image D1 that overlaps with the superimposed image D2 can be seen through the image.

"Image display surface" refers to a surface capable of displaying at least one of background image D1 and superimposed image D2. At least one of background image D1 and superimposed image D2 is displayed on image display surface S by image display device 3. In this embodiment, image display surface S is a wall surface that is white or the like, and displays at least one of background image D1 and superimposed image D2 by projecting the image onto image display device 3 configured as a projector not shown in FIG. 2.

Note that the image display surface S is not limited to this configuration, and may be, for example, a display (e.g., liquid crystal display, etc.) in which the image display surface S itself emits light to display an image. Also, one image display surface S may be defined as a collection of multiple surfaces. As an example, a second surface (e.g., a movable screen) for displaying a superimposed image D2 may be placed in front of a first surface (e.g., a wall surface) for displaying a background image D1 (e.g., toward the center of the room), and these first and second surfaces may be collectively defined as one image display surface S. In this case, the background image D1 may be displayed on the first surface by either a projector or a display, and the superimposed image D2 may be displayed on the second surface by the other of the projector and the display.

Each of the multiple image display surfaces S may be configured as a wall surface of a room R in a building. For example, each of the five surfaces of the four side walls and the ceiling surface of the room R may constitute an image display surface S. Note that only one, two, or three of the four side walls of the room R may constitute the image display surface S, and the ceiling surface may not constitute the image display surface S, and the floor surface may also constitute the image display surface S. The positional relationship of each of the multiple image display surfaces S may be a positional relationship in which the surfaces corresponding to each image display surface S (or the extended surfaces of the surfaces) intersect with each other, or a positional relationship in which the surfaces corresponding to each image display surface S (or the extended surfaces of the surfaces) face each other. In addition, the image display surface S does not have to be flat, and may be, for example, a curved surface, a bent surface, etc. The image display surface S is not limited to a wall surface, and may be, for example, a screen, a curtain, a window, etc.

In this embodiment, each of the multiple image display surfaces S is composed of five surfaces: the four side walls and the ceiling of a room R inside a building. An image of a forest is displayed across the entire surface of each of these image display surfaces S as a background image D1. In particular, an image of a sideways view of the forest is displayed on the four side walls of room R of each image display surface S, and an image of an upward view of the forest is displayed on the ceiling of room R of each image display surface S. This allows a user in room R to visually experience as if they were in a forest.

In addition, in this embodiment, a simple explanation of the background image D1 is displayed as the superimposed image D2. Specifically, the words "Healing Forest" are displayed as an image as the superimposed image D2 to explain that the background image D1 is an image of a forest intended to provide healing to the user. Here, the superimposed image D2 is displayed in the lower region of one of the side walls of the room R on each image display surface S.

The image display device 1 is configured to be capable of wired or wireless communication with the information input device 2, the image display device 3, and the stimulus generating device 4. Specifically, the image display device 1 is configured as a computer C having a control arithmetic unit, a storage device, and an input/output device as its physical configuration. The image display device 1 may be, for example, a notebook computer, a desktop computer, a tablet, or a smartphone, and a notebook computer is exemplified as the image display device 1 here.

The control and arithmetic device is composed of a controller such as a CPU (Central Processing Unit), and executes arithmetic processing while controlling the storage device and input/output device. The storage device has, for example, a main storage device and an auxiliary storage device. The main storage device is composed of, for example, a RAM (Random Access Memory). The auxiliary storage device is composed of, for example, a ROM (Read Only Memory). The input/output device has, for example, an input device such as an information input device 2 that receives data from the outside and transmits it to the storage device, and an output device such as an image display device 3 or a stimulus generating device 4 that outputs the results of calculations performed by the control and arithmetic device and stored in the storage device to the outside.

The image display device 1 executes a predetermined process, for example, by loading a program stored in ROM into RAM and executing the program loaded into RAM with the CPU. Specifically, the image display device 1 executes an image display process that displays a background image D1 and a superimposed image D2 on multiple image display surfaces S by loading an image display program P stored in ROM into RAM and executing the image display program P loaded into RAM with the CPU. Note that the computer C that constitutes the image display device 1 may have a physical configuration different from that described above.

The information input device 2 is a device capable of acquiring various types of information and transmitting (inputting) the acquired information to the image display device 1. The information input device 2 is operated by a user to acquire various types of information. For example, the information input device 2 may have a button, a touch panel, a keyboard, or the like, and may be operated by a user to acquire information such as text information. Alternatively, the information input device 2 may have an imaging device such as a camera, or various sensors such as an infrared sensor or a pressure sensor, and may acquire information regarding the user's appearance, location, behavior, or the like. Alternatively, the information input device 2 may have a sound collection device such as a microphone, and may acquire audio information based on the user's voice, etc. The information input device 2 may process the acquired information into an information format suitable for transmission to the image display device 1, and transmit the information to the image display device 1.

The image display device 3 is a device that displays at least one of the background image D1 and the superimposed image D2 on the image display surface S. As described above, in this embodiment, the image display surface S is a wall surface, so the image display device 3 is configured as a projector, and displays at least one of the background image D1 and the superimposed image D2 by projecting the image onto the image display surface S. A plurality of image display devices 3 may be provided corresponding to each of the plurality of image display surfaces S.

Here, the image display device 3 configured as a projector is divided into a background image display device 30 (first projector) for projecting a background image D1 onto the image display surface S, and a superimposed image display device 31 (second projector) for projecting a superimposed image D2 onto the image display surface S. Note that the image display device 3 may be capable of projecting both the background image D1 and the superimposed image D2 onto the image display surface S by a single image display device 3.

When the image display surface S is a display such as a liquid crystal display, the image display device 3 may be a device that controls the display to display at least one of the background image D1 and the superimposed image D2 on the display. In this case, the image display device 3 may be configured as one unit with the image display surface S configured as a display (built into the image display surface S).

The stimulus generating device 4 is a device that generates a stimulus. More specifically, the stimulus generating device 4 generates a stimulus in a predetermined area (e.g., room R) in which multiple image display surfaces S are installed. A "stimulus" is a phenomenon that can be perceived by a user. In other words, a stimulus is a phenomenon that affects at least one of the user's five senses. For example, the stimulus may be a smell (fragrance), vibration, light, sound, mist, etc. Also, the stimulus may be configured as a combination of multiple phenomena (e.g., smell and sound). When the stimulus is light, the light as the stimulus is different from the background image D1 and the superimposed image D2.

Specifically, when the stimulus is an odor, the stimulus generating device 4 may be an aroma generator. The aroma generator is a device that emits molecules (smell molecules) that can be perceived by the sense of smell. When the stimulus is vibration, the stimulus generating device 4 may be a vibrator. When the stimulus is light, the stimulus generating device 4 may be lighting. The lighting may be an LED, a fluorescent lamp, or a neon sign. When the stimulus is sound, the stimulus generating device 4 may be a speaker. When the stimulus is mist, the stimulus generating device 4 may be a mist generator. The mist generator is a device that atomizes water and releases it, and may atomize water by heat or vibration, for example. Here, "atomization" means that water is turned into tiny droplets (mist water) and released into the air.

Next, the functions of the image display device 1 will be described. Functionally, the computer C of the image display device 1 has a background image display unit 10, a superimposed image display unit 11, a layout setting unit 12, a preview image display unit 13, a stimulus generation unit 14, a stimulus setting unit 15, an image display surface change unit 16, a background image proposal unit 17, and an event input reception unit 18.

The background image display unit 10 can display a background image D1 on each of the multiple image display surfaces S. The background image display unit 10 transmits information about the background image D1 to be displayed on each of the multiple image display surfaces S to the image display device 3 (e.g., background image display device 30), thereby displaying the background image D1 on the image display surface S. The background image display unit 10 may display a preset background image D1 on the image display surface S, or may display a background image D1 determined based on information input from the information input device 2 on the image display surface S. The background image display unit 10 may display a different background image D1 on each image display surface S.

The superimposed image display unit 11 can display the superimposed image D2 on at least one of the multiple image display surfaces S by superimposing it on the background image D1 displayed on the image display surface S. The superimposed image display unit 11 transmits information about the superimposed image D2 to be displayed on at least one of the multiple image display surfaces S to the image display device 3 (for example, the superimposed image display device 31), thereby displaying the superimposed image D2 on the image display surface S. The superimposed image display unit 11 may display a preset superimposed image D2 on the image display surface S, or may display a superimposed image D2 determined based on information input from the information input device 2 on the image display surface S. The superimposed image display unit 11 may also display the superimposed image D2 on a preset image display surface S among the multiple image display surfaces S, or may display the superimposed image D2 on an image display surface S selected based on information input from the information input device 2.

The layout setting unit 12 sets a layout for displaying the background image D1 and the superimposed image D2 on the image display surface S. The "layout" refers to the manner in which the background image D1 and the superimposed image D2 are displayed on the image display surface S. The layout may be a static layout or a dynamic layout. The "mode" refers to how the background image D1 and the superimposed image D2 are displayed. For example, the mode of the background image D1 and the superimposed image D2 may include at least any information such as the position, size, and range displayed on the image display surface S. Furthermore, the mode of the background image D1 and the superimposed image D2 may include information on which image display surface S the background image D1 and the superimposed image D2 are displayed.

A "static layout" is a layout in which the manner in which the background image D1 and the superimposed image D2 are displayed does not change over time. "Does not change over time" means that the images do not move like a video, and the images (still images) do not switch at a predetermined timing.

A "dynamic layout" is a layout in which the manner in which the background image D1 and the superimposed image D2 are displayed changes over time. "Changing over time" may mean that the images move like a video, or that the images (still images) are switched at a predetermined timing. "The images move like a video" may mean that the position at which at least a portion of the background image D1 and the superimposed image D2 are displayed moves, or that the image display surface S on which at least a portion of the background image D1 and the superimposed image D2 are displayed changes. "Predetermined timing" may be a timing defined by a preset time interval, in which case the time interval may be, for example, a 5-minute interval or a 10-minute interval.

The preview image display unit 13 displays a preview image that represents a state in which the background image D1 and the superimposed image D2 are displayed based on the layout set by the layout setting unit 12. The preview image display unit 13 may display the preview image, for example, on a screen provided on the image display device 1, or on a screen of an external device connected to the image display device 1.

A "preview image" is an image showing the background image D1 and superimposed image D2 displayed on the image display surface S. The preview image may be an image that displays the background image D1 and superimposed image D2 displayed on each image display surface S for each image display surface S. Alternatively, the preview image may be an image that displays the background image D1 and superimposed image D2 displayed on multiple image display surfaces S (e.g., all image display surfaces S) in three dimensions in accordance with the state in which the multiple image display surfaces S are actually arranged, or may be an image that displays the file name of an image file (or video file) that contains information on the background image D1 and superimposed image D2 at the position where the multiple image display surfaces S are actually arranged.

The stimulus generating unit 14 generates a stimulus according to the background image D1 and the superimposed image D2 displayed on the image display surface S. The stimulus generating unit 14 transmits information about the stimulus to be generated to the stimulus generating device 4, thereby operating the stimulus generating device 4 to generate the stimulus. The content of the stimulus to be generated by the stimulus generating unit 14 according to the background image D1 and the superimposed image D2 displayed on the image display surface S may be specified in advance, or may be set each time by the stimulus setting unit 15 described later.

The stimulus setting unit 15 sets the content of the stimulus generated by the stimulus generating unit 14. The "content of the stimulus" may mean the quantitative characteristics of the stimulus, or may mean the qualitative characteristics of the stimulus.

The "quantitative characteristic of the stimulus" may be, for example, a characteristic specified by an index such as the intensity, amount, or size of the stimulus. Specifically, if the stimulus is an odor, it may be the intensity of the emitted odor (the number or concentration of emitted odor molecules). If the stimulus is vibration, it may be the intensity or size of the vibration (amplitude, period, acceleration, etc.). If the stimulus is light, it may be the intensity of the emitted light (brightness, etc.). If the stimulus is sound, it may be the volume of the emitted sound (sound pressure, etc.). If the stimulus is mist, it may be the amount of mist emitted (amount of water, number of water droplets per unit volume, etc.).

The "qualitative characteristics of the stimulus" may be, for example, a characteristic designated as the type of stimulus. Specifically, if the stimulus is an odor, it may be the type of odor generated (the type of odor molecules released). If the stimulus is vibration, it may be the pattern of vibration. If the stimulus is light, it may be the color of the light generated or the pattern of light emission. If the stimulus is sound, it may be the audio content, melody, scale, quality, tone, etc. of the sound generated. If the stimulus is mist, it may be the temperature of the mist generated or the pattern of mist generation.

The stimulus setting unit 15 may set the content of the stimulus generated by the stimulus generating unit 14 to change when the background image D1 or the superimposed image D2 is switched. The stimulus setting unit 15 may also set the content of the stimulus generated by the stimulus generating unit 14 according to the content of the background image D1 or the superimposed image D2 detected by the information input device 2 configured as an imaging device such as a camera, or according to the number of image display surfaces S on which the background image D1 or the superimposed image D2 is displayed.

The stimulus setting unit 15 may set different stimuli when the background image D1 is displayed on each of the multiple image display surfaces S by the background image display unit 10 and when the superimposed image D2 is displayed on at least one of the multiple image display surfaces S by the superimposed image display unit 11 and when the superimposed image D2 is not displayed on any of the multiple image display surfaces S by the superimposed image display unit 11. As a specific example, when the stimulus is sound, the stimulus setting unit 15 may set the volume of the sound generated by the stimulus generating unit 14 to be smaller when the background image D1 is displayed on each of the multiple image display surfaces S by the background image display unit 10 and when the superimposed image D2 is displayed on at least one of the multiple image display surfaces S by the superimposed image display unit 11, compared to when the superimposed image D2 is not displayed on any of the multiple image display surfaces S by the superimposed image display unit 11. This makes it possible to create an environment in which the user can easily focus their attention on the superimposed image D2, for example.

The image display surface change unit 16 changes the image display surface S on which the superimposed image D2 is displayed by the superimposed image display unit 11 to another image display surface S. The image display surface change unit 16 may change the image display surface S on which the superimposed image D2 is displayed to another image display surface S, for example, based on information received from the information input device 2. In this case, the information input device 2 may be operated by a user to obtain information on the image display surface S on which the superimposed image D2 is to be displayed, and transmit the obtained information to the image display surface change unit 16 of the image display device 1.

For example, if the information input device 2 is an imaging device such as a camera, or various sensors such as an infrared sensor or a pressure sensor, the image display surface change unit 16 may detect that the user has made a specific gesture on the image display surface S (for example, a swipe gesture in which the user moves the fingers, etc., in a sweeping motion), and may change the image display surface S on which the superimposed image D2 is displayed to another image display surface S. At this time, the gesture such as a swipe operation made by the user may require that the user actually touch the image display surface S, or may not require that the gesture be made while touching the image display surface S.

The background image proposal unit 17 proposes a background image D1 to be displayed on each of the multiple image display surfaces S by the background image display unit 10. The background image proposal unit 17 may propose a background image D1 to be displayed on each of the multiple image display surfaces S by the background image display unit 10 based on a superimposed image D2 displayed on at least one of the multiple image display surfaces S by the superimposed image display unit 11. For example, the background image proposal unit 17 may propose a background image D1 based on a keyword included in the superimposed image D2 displayed on the image display surface S, or a design or color of the superimposed image D2. In this case, the background image proposal unit 17 may select the background image D1 to be proposed using a trained model acquired by machine learning. In other words, the background image proposal unit 17 may select the background image D1 to be proposed using a so-called AI (Artificial Intelligence). Alternatively, the background image suggestion unit 17 may store a correspondence map in advance that associates the background image D1 with the superimposed image D2, and use the correspondence map to select the background image D1 to be proposed.

The background image proposal unit 17 may propose a background image D1 to be displayed on each of the multiple image display surfaces S by the background image display unit 10 based on an event input accepted by the event input acceptance unit 18 described below. Even in this case, the background image proposal unit 17 may select the background image D1 to be proposed using a trained model acquired by machine learning (i.e., using so-called AI). Alternatively, the background image proposal unit 17 may store a correspondence map in which the background image D1 is associated with an event in advance, and use the correspondence map to select the background image D1 to be proposed.

The event input reception unit 18 receives input of an event performed by a user. An "event" is a type of event, and may be, for example, a meeting, a seminar, or a dinner party. Furthermore, an "event performed by a user" may mean an event performed by a user in a situation where the image display device 1 is used, and more specifically, may mean an event held in a room R in which multiple image display surfaces S are provided. The event input reception unit 18 may receive input of an event performed by a user, for example, based on information received from the information input device 2.

[Image display program]
An explanation will be given of the image display program P for causing the computer C to function as the image display device 1. Fig. 3 is a block diagram showing the image display program P. The image display program P shown in Fig. 3 is a program for displaying a background image D1 on each of a plurality of image display surfaces S, and displaying a superimposed image D2 on at least one of the plurality of image display surfaces S.

The image display program P includes a main module MM, a background image display module M10, a superimposed image display module M11, a layout setting module M12, a preview image display module M13, a stimulus generation module M14, a stimulus setting module M15, an image display surface change module M16, a background image proposal module M17, and an event input reception module M18.

The main module MM is a part that controls the computer C in an integrated manner. The functions realized by executing the background image display module M10, the superimposed image display module M11, the layout setting module M12, the preview image display module M13, the stimulus generation module M14, the stimulus setting module M15, the image display surface change module M16, the background image proposal module M17, and the event input reception module M18 are similar to the functions of the background image display unit 10, the superimposed image display unit 11, the layout setting module 12, the preview image display unit 13, the stimulus generation unit 14, the stimulus setting unit 15, the image display surface change module 16, the background image proposal unit 17, and the event input reception unit 18. Note that the image display program P may not include some of the modules described above other than the main module MM, the background image display module M10, and the superimposed image display module M11.

[Action and Effect]
As described above, the image display program P causes the computer C to function as a background image display unit 10 capable of displaying a background image D1 on each of multiple image display surfaces S, and a superimposed image display unit 11 capable of displaying a superimposed image D2 on at least one of the multiple image display surfaces S by superimposing it on the background image D1 displayed on the image display surface S.

The image display device 1 includes a background image display unit 10 capable of displaying a background image D1 on each of a plurality of image display surfaces S, and a superimposed image display unit 11 capable of displaying a superimposed image D2 on at least one of the plurality of image display surfaces S by superimposing it on the background image D1 displayed on the image display surface S.

At least one of the image display program P and the image display device 1 can display not only the background image D1 on each of the multiple image display surfaces S, but also the overlay image D2 superimposed on the background image D1 on at least one of the image display surfaces S. This makes it possible to increase the degree of freedom in the manner in which visual information is provided to the user.

The image display program P causes the computer C to function as a layout setting unit 12 that sets a layout for displaying the background image D1 and the superimposed image D2 on the image display surface S. This makes it possible to set the layout for displaying the background image D1 and the superimposed image D2 on the image display surface S in a desired manner. This makes it possible to further increase the degree of freedom in the manner in which visual information is provided to the user.

The image display program P causes the computer C to function as a preview image display unit 13 that displays a preview image showing the state in which the background image D1 and the superimposed image D2 are displayed based on the layout set by the layout setting unit 12. This makes it possible to visually confirm in advance the layout in which the background image D1 and the superimposed image D2 are displayed on the image display surface S.

In the image display program P, the layout is a dynamic layout in which the manner in which the background image D1 and the superimposed image D2 are displayed changes over time. This allows for greater freedom in the manner in which visual information is provided to the user.

The image display program P causes the computer C to function as a stimulus generator 14 that generates a stimulus according to the background image D1 or the superimposed image D2 displayed on the image display surface S. This makes it possible to provide the user with information in the form of various stimuli in addition to the background image D1 and the superimposed image D2. This makes it possible to further increase the degree of freedom in the manner in which information is provided to the user, including manners other than visual manners.

The image display program P causes the computer C to function as a stimulus setting unit 15 that sets the content of the stimulus generated by the stimulus generating unit 14. This makes it possible to set the content of the stimulus to be generated to the desired content. This makes it possible to further increase the degree of freedom in the manner in which information is provided to the user.

In the image display program P, when the background image display unit 10 displays a background image D1 on each of the multiple image display surfaces S, the stimulus setting unit 15 sets stimuli with different contents when the superimposed image display unit 11 displays a superimposed image D2 on at least one of the multiple image display surfaces S and when the superimposed image display unit 11 does not display a superimposed image D2 on any of the multiple image display surfaces S. This makes it possible to generate stimuli with different contents depending on whether the superimposed image D2 is displayed on at least one of the multiple image display surfaces S, thereby further increasing the degree of freedom in the manner in which information is provided to the user.

The image display program P causes the computer C to function as an image display surface change unit 16 that changes the image display surface S on which the superimposed image D2 is displayed by the superimposed image display unit 11 to another image display surface S. This makes it possible, for example, to move the superimposed image D2 to an image display surface S that is easily visible to the user, or to move the superimposed image D2 to an image display surface S that is difficult for the user to see. This makes it possible to provide visual information to the user in a desired manner.

The image display program P causes the computer C to function as a background image suggestion unit 17 that suggests background images D1 to be displayed on each of the multiple image display surfaces S by the background image display unit 10. This makes it possible to suggest an appropriate background image D1 to the user. This also reduces the effort required for the user to select the background image D1 by themselves, improving convenience.

In the image display program P, the background image suggestion unit 17 suggests a background image D1 to be displayed on each of the multiple image display surfaces S by the background image display unit 10 based on a superimposed image D2 displayed on at least one of the multiple image display surfaces S by the superimposed image display unit 11. This makes it possible to suggest to the user a background image D1 that matches the displayed superimposed image D2.

The image display program P causes the computer C to function as an event input receiving unit 18 that receives input of an event performed by a user, and the background image suggestion unit 17 proposes a background image D1 to be displayed on each of the multiple image display surfaces S by the background image display unit 10 based on the event input received by the event input receiving unit 18. This makes it possible to suggest to the user a background image D1 that matches the event performed by the user.

[Modifications]
The above-described embodiment can be implemented in various forms that are modified or improved based on the knowledge of those skilled in the art.

For example, in the above-described embodiment, each of the multiple image display surfaces S is configured as a wall surface of a room R in a building. In other words, the image display device 1 is used indoors. However, the image display device 1 may also be used outdoors. In this case, each of the multiple image display surfaces S may be a partition or the like installed outdoors.
