[0011] A spatial design system according to an embodiment of the present disclosure will be described in detail below with reference to the drawings. Note that each of the embodiments described below represents a specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, component arrangements and connection forms, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Therefore, among the components according to the following embodiments, components not recited in independent claims will be described as optional components.

[0012] Furthermore, each figure is a schematic diagram and is not necessarily an exact illustration. Therefore, for example, the scales of the figures do not necessarily match. Furthermore, in each figure, substantially the same components are given the same reference numerals, and redundant explanations are omitted or simplified.

[0013] (Embodiment) [overview] In the following embodiments, an office space design system will be described assuming an office as an example of space, but the space may be an office, a home building and garden, or a public facility such as a library or park. The space may also be either an indoor space or an outdoor space.

[0014] When constructing a space, it is often important to consider what kind of emotional value to impart to users who will use the space. In particular, when users are working in the space, there is a correlation between work efficiency and emotional value for each type of work. Therefore, it is necessary to design the space so that it imparts emotional value according to the type of work from the perspective of work efficiency. To arbitrarily change the emotional value, as shown in Patent Document 1, for example, the emotional value desired by the user can be acquired and the space design can be configured to impart that emotional value. The space design can be configured by adjusting the parameters of one or more environmental elements (hereinafter referred to as components or simply elements) that constitute the environment in the space. In this way, the space can be designed by determining the numerical values ​​of the parameters of one or more elements according to the emotional value. In this case, it is effective to output support information, for example, by correlating the respective levels of emotional value (in other words, the strength of emotional value) with the numerical values ​​of the parameters of one or more elements. Users can directly refer to this support information to design an appropriate space themselves, or the support information can be input into an automatic space design system to automatically design an appropriate space. In this embodiment, the explanation will be focused on an example of inputting support information into an automatic spatial design system, but as described above, the support information may also be output for user reference and presented as an image on a display device, for example.

[0015] FIG. 1 is a diagram illustrating the relationship between affective values ​​and environmental components according to an embodiment. FIG. 1 illustrates a stepwise correlation in which components affect the impression a user gets from a space, changing the user's mood (mood factors), and changing the affective values ​​given to the user. Such correlations are also referred to as an affective structure model. In the affective structure model, for example, the influence of each environmental component on the impression the user gets from the space, such as a sense of serenity, a sense of liveliness, and a sense of freshness, is summarized as the strength of the correlation. Furthermore, when each element of the impression the user gets from the space subsequently changes each of the user's mood factors, the influence of each element of the user's mood factors, such as a change to sedation, a change to elation, and a change to awakening, is summarized as the strength of the correlation (represented by the thickness of the arrow in the figure). Similarly, the affective values ​​given to the user by changes in the user's mood factors are also summarized as the strength of the correlation.

[0016] Here, as a result of extensive research, the inventors of the present application have found that the sensibility structure model shown in Fig. 1 exhibits different correlations depending on the usage scenario of the space. Therefore, it can be said that different sensibility structure models must be used for different usage scenarios. Therefore, in the present disclosure, sensibility structure models are prepared in advance corresponding to each of the usage scenario options, and the user's usage scenario is input to select and use the appropriate sensibility structure model, thereby making it possible to more appropriately adjust the parameters of the environmental components and design a space.

[0017] Although FIG. 1 illustrates six elements, namely, spatial lighting, video, sound, plants, airflow, and fragrance, the combination of elements is not limited to this. In the present disclosure, the following description can be applied to a combination of at least one element, for example, lighting, video, and sound, with one or more other elements that are the same as or different from the elements. Specifically, for example, the elements may include lighting as one element and one or more elements other than lighting. The other element may be any of the six elements, namely, spatial lighting, video, sound, plants, airflow, and fragrance, or may be a seventh element that is not any of the six elements, namely, spatial lighting, video, sound, plants, airflow, and fragrance. In the following embodiments, a combination of lighting, sound, video, and plants will be used as an example. Furthermore, in the present disclosure, a parameter refers to a controllable portion of each element, and corresponds to, for example, task illuminance (T illuminance), ambient illuminance (A illuminance), and color temperature for lighting as a component. When lighting is included as one element and lighting is included as another element, there is also a combination of parameters where one parameter is the lighting task illuminance (T illuminance) and another parameter is ambient illuminance (A illuminance). Other lighting parameters include lighting orientation, placement, desk illuminance, and wall illuminance. Video parameters include image brightness, saturation, projection angle, and video size. Audio parameters include audio orientation, placement, frequency, and directivity.

[0018] In the following description, an example will be given in which a combination of five affective values, namely, the degree of fatigue reduction, the degree of interaction activity, the degree of vitality improvement, the degree of creativity improvement, and the degree of concentration improvement, that a user feels in an environment realized in a space, is used as the affective value. However, the embodiment is applicable to a combination including at least one of the five affective values, namely, the degree of fatigue reduction, the degree of interaction activity, the degree of vitality improvement, the degree of creativity improvement, and the degree of concentration improvement. However, a combination including at least one of the five affective values ​​is a concept that includes a combination that includes only one of the five affective values ​​and does not include the others. Each of the affective values ​​here is defined as follows:

[0019] The degree of fatigue reduction is a perceptual value that indicates the degree of some index that affects the amount of accumulated fatigue in the user, such as the difficulty of fatigue building up, the difficulty of stress building up, the degree to which fatigue is alleviated, and the degree to which stress is alleviated.

[0020] The degree of interaction activity is a perceptual value that indicates the degree of some index regarding the ease of communication between one user and another, such as the ease with which a conversation can be lively among multiple users, the ease with which users can talk to other users, and the ease with which users can express their opinions in conversation.

[0021] The degree of vitality improvement is a perceptual value that indicates the degree of some indicator related to the mental state necessary for the user to complete a task, such as how easily the user feels energized to complete a task such as work, how easily the user feels motivated to complete a task such as work, or how lively the user is able to work on a task such as work.

[0022] The degree of improvement in creativity is a perceptual value that indicates the degree of some index relating to the ease with which the user can express their creative thinking, such as the richness of their imagination, the ease with which they can come up with novel ideas, the ease with which they can organize their thoughts, and the ease with which they can switch their thinking.

[0023] The degree of improvement in concentration is a perceptual value that indicates the degree of some indicator regarding the ease with which the user can maintain concentration on a task, such as the ease of concentrating on a task such as work, the degree of immersion in the task, or the degree to which distraction to the surroundings is suppressed.

[0024] In the following, instead of the graded correlations such as component element-impression-mood factor-perceived value shown in Figure 1, a sensory structure model (table data, described in detail using Figure 3) that shows simple and direct correlations such as component element-perceived value, which are estimated from a combination of component elements, is used as the sensory structure model. However, a model that more accurately summarizes graded correlations such as those shown in Figure 1 may also be used as the sensory structure model.

[0025] [System Configuration] FIG. 2 is a diagram illustrating the functional configuration of a space design system according to an embodiment. In addition to the space design system 10, FIG. 2 also illustrates an operation terminal 20. The operation terminal 20 is a terminal such as a smartphone, tablet, or PC owned by a business operator engaged in space design, and is used to access the space design system 10 and input and output information to the space design system 10 when designing a space. The space design system 10 is used, for example, by a business operator such as a renovation contractor or space designer to design a space as part of their business. For example, when designing a space at the request of an owner of a space, the business operator accesses the space design system 10 from the operation terminal 20 and inputs information into the space design system 10 based on an interview with the owner. The information input here includes the usage scenarios described above. Note that the owner of the space is also the user of the space, but the user of the space does not have to be the same as the owner of the space.

[0026] A usage scenario is a usage situation that corresponds to the intended use that the owner of the space expects the users of the space to use. For example, the usage scenario can be selected from among co-working, solo-working, discussion, and recharge. Note that these usage scenario options are only examples, and there may be fewer options, such as co-working and solo-working, or a fifth usage scenario may be included in addition to the four usage scenarios exemplified above.

[0027] The space design system 10 is realized as an information processing server such as a cloud server or an edge server, and specifically, is realized by a so-called computer that executes a predetermined program using a processor and a memory.

[0028] The space design system 10 includes an input unit 11, a storage unit 12, and a calculation unit 13. The input unit 11 is a functional part that accepts input of information to the space design system 10 via an operation terminal 20. Specifically, the input unit 11 accepts input of a usage scenario, input of perceptual values ​​that are prioritized by the user (or for the user assumed by the owner), and input of constraints on the numerical values ​​of parameters of components in the space.

[0029] The storage unit 12 is a functional part related to the information storage function of the server. The storage unit 12 stores the same number of sensory structure models as the number of usage scenario options, each associated with a corresponding one of the usage scenario options. FIG. 3 is a diagram for explaining the sensory structure model according to the embodiment. Note that FIG. 3 also shows an enlarged view of the coworking table data. As shown in FIG. 3, multiple sensory structure models are prepared for each usage scenario. Each sensory structure model constitutes table data in which, for each combination of parameters for the environmental components, a numerical value corresponding to the strength of the sensory value perceived by the user in the environment realized by the parameters of the combined numerical components is associated. For example, in FIG. 3, the environment is constituted by a set of six parameters: three parameters for the lighting element, one parameter for the video element, one parameter for the sound element, and one parameter for the planting element. It is assumed that each element has three numerical values, A to C, set. Therefore, 3 to the power of 6 = 729 parameter sets (sets of numerical values ​​for each parameter) are considered as the conditions for the elements that constitute the environment. A set of values ​​for each of the perceptual values, that is, the strength of each of the perceptual values, is associated with each of the parameter sets.

[0030] As an example, suppose this table data is output as is in response to the input of only a certain usage scenario. The output table data contains the strength of each of the 729 possible corresponding emotional values ​​and the numerical values ​​of the element parameters. If the user can recognize these 729 possible corresponding relationships, they can, to a certain extent, design a space that can impart the desired emotional values. In other words, even if the input of a usage scenario is output as support information, the user can more appropriately design an environment.

[0031] However, the number of correspondence relationships, 729, may be too many for a user to recognize. Therefore, in this embodiment, the calculation unit 13 is provided with a function for extracting fewer than 729 correspondence relationships by accepting, as input, the user's desired affective value or parameters of configurable elements, etc., and using them as filter conditions for the 729 correspondence relationships. In other words, the calculation unit 13 performs extraction using filter conditions for all the cases (all cases) of the parameters, thereby deriving fewer than all the correspondence relationships (for example, less than half, the number of cases that satisfy the condition that the numerical value of the strength is equal to or greater than a predetermined threshold, a predetermined percentage of the total number of cases, or a small number such as 1 to 10), making it easier for the user to recognize. In this way, the calculation unit 13 has a filtering function for performing extraction using filter conditions. The specified percentage may be less than 10%, such as 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, or 9%, or may be more than 10% but less than 50%, such as 10%, 20%, 30%, or 40%, or may be more than 50%, such as 50%, 60%, 70%, 80%, or 90%.

[0032] In this embodiment, the parameters of the extracted corresponding elements are input into an automatic space design system, and the parameters that realize the automatically designed space (i.e., the parameters of each element to be set) are output. The extraction of the correspondence and the parameters of each element at that time will be described in more detail below.

[0033] In Figure 3, in the table data of the coworking sensory structure model, if the parameter values ​​for desk surface illuminance among the lighting elements are A, the parameter value for spotlight illuminance is C, the parameter value for color temperature is A, the parameter value for type of video among the video elements is A, the parameter value for type of sound among the sound elements is A, and the parameter value for the amount of plants among the planting elements is A, then the corresponding values ​​are 1.0 for the degree of improvement in concentration, 1.3 for the degree of reduction in fatigue, 1.4 for the degree of social activity, 1.7 for the degree of improvement in vitality, and 1.5 for the degree of improvement in creativity. Note that the higher the sensory value values ​​here, the stronger the sensory value (indicating a more beneficial effect for users), with the minimum value being 1.0 and the maximum value being 5.0.

[0034] Such table data is created before it is used in the design of the space. To create the table data, for example, a survey of users for each usage scenario may be conducted in advance to compile the impressions or emotional values ​​given to an environmental space configured under 729 different conditions. When compiling the emotional values ​​given, the table data is created directly. On the other hand, when compiling the impressions given, the correlation between the components and the impressions in the emotional structure model becomes clear. Therefore, the correlation between the impressions, mood factors, and emotional values ​​can be calculated from general correlations to create the table data. Furthermore, instead of conducting a survey under all 729 different conditions, it is also possible to determine representative conditions that can easily measure the impact of each component, conduct a survey under those representative conditions, and supplement the results under the remaining conditions with estimates.

[0035] Returning to FIG. 2, the calculation unit 13 is a functional part that performs space design processing, i.e., extracts correspondences using filter conditions in response to input information, and determines and outputs parameter sets for each element of the environment from the extracted correspondences. The calculation unit 13 includes a processing unit 131 that performs extraction using a filtering function in response to input information and determines parameter sets for each element of the environment after extraction, and an output unit 132 that generates and outputs output data for the determined parameter sets. Further detailed functions of the calculation unit 13 will be described below in conjunction with the operation of the space design system 10 using FIG. 4.

[0036] [Operation] 4 is a flowchart showing an example of the operation of the space design system according to the embodiment. As shown in FIG. 4, when the operation of the space design system 10 starts, the space design system 10 first reads out a stored sensory structure model from the storage unit 12 (S101). Meanwhile, the input unit 11 accepts input from the user via the operation terminal 20 (more precisely, input by the business operator using the space design system 10 based on what the user has heard) (S102).

[0037] 5 is a diagram illustrating an example of information to be input according to the embodiment. As shown in FIG. 5, the business operator selects one of the usage scenarios displayed on the touch panel of the operation terminal 20 that corresponds to the user's use of the space.

[0038] Also, as shown in the figure, if there are constraints on the parameter values ​​of each element in the space, the input unit 11 also accepts input of those constraints in step S102. Constraints include, for example, "bright lighting," "prefer quieter sounds," "illumination cannot be changed," "I like plants," etc., as shown in the figure.

[0039] For example, if the input of a constraint condition such as "brighter lighting" is received, only those parameters A to C that are equal to or greater than a predetermined threshold value for both the desk surface illuminance and the spotlight illuminance will be considered for parameter set selection. In this way, the constraint conditions include those that set threshold conditions for the parameter values ​​of each element.

[0040] For example, if the constraint "I prefer quieter sounds" is input, only the numerical value corresponding to "no sound" (silence) among A to C for the sound type parameter will be considered when selecting a parameter set. In this way, the constraints include those that limit the numerical value of the parameter of each element to one numerical value.

[0041] Furthermore, for example, if the input of the constraint condition "illuminance cannot be changed" is received, only the numerical values ​​among A to C corresponding to the predetermined invariable values ​​for both the desk surface illuminance and the spotlight illuminance parameters will be considered when selecting a parameter set.

[0042] Also, for example, when the input of the constraint condition "I like planting" is received, only the numerical values ​​of A to C for the parameter of the number of plants where the number of plants is 1 or more are considered when selecting a parameter set.

[0043] Furthermore, as shown in the figure, when there is a prioritized perceptual value among the five perceptual values ​​in the space, the input unit 11 also receives an input regarding the prioritized perceptual value in step S102. As the prioritized perceptual value, for example, as shown in the figure, an input is made to select one or more of "reducing fatigue," "active social interaction," "improving vitality," "improving creativity," and "improving concentration." The change in the processing in the calculation unit 13 depending on whether or not there is an input of a prioritized perceptual value among the perceptual values ​​will be described later.

[0044] Returning to FIG. 4, the processing unit 131 determines, from among the read sensory structure models, a sensory structure model corresponding to the usage scenario for which input has been accepted (S103). Here, assuming that a usage scenario for a coworking environment has been selected, the description will continue with reference to an example of a sensory structure model corresponding to the coworking environment shown in FIG. 3. Note that the processing of steps S101 to S103 described above does not need to be performed in this order. For example, if step S102 is performed first and input of the usage scenario is accepted, step S103 may be performed to first determine a sensory structure model corresponding to the usage scenario, and then step S101 may be performed to read only the sensory structure model determined as corresponding to the usage scenario from the storage unit 12. As described above, the order of the steps shown in FIG. 4 is merely an example, and the steps may be interchanged as long as there is no contradiction. Furthermore, the process of reading a sensory structure model from the storage unit shown in step S101 may be a step of reading all sensory structure models stored in the storage unit, as described in FIG. 4, or may be a step of reading only the sensory structure model determined as corresponding to the usage scenario from among the sensory structure models stored in the storage unit, as in the other example described above.

[0045] Next, the processing unit 131 refers to the determined affective structure model to extract and output a correspondence relationship in which the numerical value of the strength of the prioritized affective value is the maximum value (S104). In this example, the filter condition is that the prioritized affective value is the maximum value. If multiple prioritized affective values ​​are input, the numerical values ​​of the strength of the multiple prioritized affective values ​​are calculated as a total value for each correspondence relationship, and the correspondence relationship in which the total value is the maximum value is extracted.

[0046] Thereafter, the processing unit 131 determines a parameter set from the extracted correspondence (S105). When the prioritized perceptual value is included in the received input information, for example, if "interaction activity level" is determined as the prioritized perceptual value, the parameter set with the maximum prioritized perceptual value is the parameter set corresponding to condition number 2 as shown in FIG. 3, in which, among the lighting elements, the parameter value of the desk surface illuminance is B, the parameter value of the spotlight illuminance is B, the parameter value of the color temperature is C, among the image elements, the parameter value of the image type is B, among the sound elements, the parameter value of the sound type is C, and among the planting elements, the parameter value of the planting amount is C. Note that, if there are two or more parameter sets with the maximum prioritized perceptual value, the parameter set with the next-highest prioritized perceptual value may be determined from the two or more parameter sets. The next-highest prioritized perceptual value may be, for example, a perceptual value that is prioritized for the input usage scene that is pre-associated with the usage scene. Alternatively, when two or more affective values ​​to be prioritized are included in the received input information, one of them may be used as the affective value to be prioritized next.

[0047] When two or more priority affective values ​​are included in the received input information, one of them may be set as the most priority affective value and the other as the second priority affective value, which may be automatically performed on the processing unit 131. When two or more priority affective values ​​are included in the received input information, a parameter set with the maximum value of the affective value may be determined for each of the priority affective values, and the two or more parameter sets may be displayed in parallel in the output data (as exemplified in FIG. 8, which will be described later).

[0048] Furthermore, if a constraint is set when determining a parameter set that only parameter sets for which the numerical value of the parameter for the type of sound among the sound elements is B are considered, then the parameter set surrounded by the bold rectangle in Fig. 3 and corresponding to condition number 3 is determined. That is, in this case, a correspondence within the constraint that satisfies the filter condition that the numerical value of the parameter for the type of sound among the sound elements, which is the constraint, is extracted, and the parameter set is determined. That is, the parameter set is determined as follows: among the lighting elements, the numerical value of the parameter for the illuminance of the desk surface is C, the numerical value of the parameter for the illuminance of the spotlight is A, and the numerical value of the parameter for the color temperature is B; among the image elements, the numerical value of the parameter for the type of sound is C; among the sound elements, the numerical value of the parameter for the type of sound is B; and among the planting elements, the numerical value of the parameter for the amount of vegetation is B.

[0049] On the other hand, if the prioritized perceptual value is not included in the accepted input information, the parameter set may be determined by referring to the determined perceptual structure model for the perceptual value prioritized in the input usage scene that is pre-linked to the usage scene (i.e., the perceptual value recommended to be prioritized for the usage scene), extracting a correspondence relationship in which the numerical value of the strength of the prioritized perceptual value is the maximum value. In other words, the filter condition in this case is that the numerical value of the strength of the prioritized perceptual value that is pre-determined to be prioritized in the usage scene is the maximum value.

[0050] Returning to FIG. 4, the output unit 132 generates and outputs output data including the determined parameter set (S106). FIG. 6 is a diagram for explaining an example of output data according to an embodiment. As shown in FIG. 6, the output data includes the numerical values ​​of the parameters of each element ("environment control parameters" in the diagram). The output data may also include information on the balance of each perceptual value imparted in an environment made up of each element when each parameter is set in the parameter set.

[0051] The parameter set output in this way can be said to be a parameter set for designing a more appropriate space, because it uses an appropriate sensory structure model that corresponds to the user's usage scenario. Furthermore, the correspondence relationships output as support information during the process, i.e., information that corresponds the strength of each sensory value with the parameter values ​​of each element, is also useful for deriving such a parameter set automatically or by the user. Therefore, the output correspondence relationships or parameter sets make it possible to design a more appropriate space.

[0052] [Variation 1] Modifications of the above-described embodiment will be described below with reference to Figures 7 and 8. In the modifications described below, differences from the above-described embodiment will be mainly described, and descriptions of points that are substantially the same as those in the above-described embodiment will be omitted or simplified.

[0053] Fig. 7 is a flowchart showing an example of the operation of a space design system according to a modified example of the embodiment. Fig. 8 is a diagram for explaining an example of output data according to the modified example of the embodiment. As shown in Fig. 7, the space design system according to this modified example differs from the operation of space design system 10 according to the embodiment shown in Fig. 4 in that step S201 is additionally executed and step S106a is executed instead of step S106, but is otherwise the same.

[0054] In this modification, after determining the parameter set in step S105, the output unit 132 selects a virtual space (S201). The virtual space here is a virtual image of the office environment with the parameter set determined above, and can be used to visually determine whether the determined parameter set is appropriate. A virtual space image is created in advance for each parameter set, associated with the parameter set, and stored in the storage unit 12. In other words, selecting a virtual space in step S201 means selecting a virtual space associated with the parameter set. The virtual space image differs for each parameter set with respect to the visually affecting elements of the parameter set, namely, lighting, video, and vegetation. In other words, the same virtual space image is commonly used for parameter sets in which the lighting, video, and vegetation elements have the same parameter values ​​and only the sound parameter values ​​differ. However, since the selected virtual space is also used for output data, depending on the type of output data, it may include not only an image visually representing the virtual space but also sound playback.

[0055] Furthermore, the image of the virtual space does not need to be created in advance, but may be generated sequentially by processing a reference image according to the parameter set. In this case, the selection of the virtual space in step S201 means selecting the virtual space generated as an image.

[0056] Then, the output unit 132 generates and outputs output data including the determined parameter set and the selected virtual space (S106a). Fig. 8 is a diagram for explaining an example of output data according to a modified example of the embodiment. As shown in Fig. 8, the output data includes the numerical values ​​of the parameters of each element ("environment control parameters" in the diagram) as well as an image of the virtual space (and also audio depending on the form of the output data).

[0057] [Variation 2] In the embodiment described above, an example was described in which the filtering function was used to extract a correspondence relationship in which the numerical value of the strength of the affective value or the total value thereof was the maximum value. That is, in the embodiment described above, the space design system 10 extracted one to several correspondence relationships, which are less than ten, and output a parameter set. In this modified example, the filtering function is used to extract a number of correspondence relationships that is fewer than all the possible relationships but greater than the one to several examples described in the embodiment described above.

[0058] Specifically, in step S104, the processing unit 131 performs the filtering function using a filter condition that the value is within the top 10% or is equal to or greater than a threshold. That is, when focusing on a certain emotional value, the processing unit 131 sorts the numerical values ​​of the emotional value's strength in descending order and extracts correspondences indicating the top 10 numerical values. Alternatively, when focusing on a certain emotional value, the processing unit 131 uses a threshold for the numerical value of the emotional value's strength to extract correspondences indicating numerical values ​​equal to or greater than the threshold. The threshold may be set appropriately depending on the number of correspondences extracted. For example, the user may be able to adjust the threshold arbitrarily based on the number of extracted correspondences. If there are two or more emotional values ​​of interest, such as when multiple emotional values ​​are input as prioritized emotional values, a filter condition may be used that the total value of the numerical values ​​indicating the emotional value of the interest in each correspondence is within a predetermined percentage of the top or is equal to or greater than a threshold. Alternatively, even if multiple perceptual values ​​are not input as the perceptual value to be prioritized, the numerical values ​​of the strengths of the perceptual values ​​may be used as a total value for each correspondence relationship to extract the maximum value, or a filter condition may be used such that the maximum value is within a predetermined percentage from the top, or is equal to or greater than a threshold. Note that the predetermined percentage may be a percentage less than 10%, such as 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, or 9%, or may be a percentage of 10% or more but less than 50%, such as 10%, 20%, 30%, or 40%, or may be a percentage of 50% or more, such as 50%, 60%, 70%, 80%, or 90%.

[0059] In such a case, the number of extracted correspondence relationships is likely to be relatively large, so the output data may be in a format that lists only the correlations of numerical values ​​as shown in Fig. 3, rather than the output data as a parameter set for each individual correspondence relationship as shown in Fig. 6. In other words, the filtering result output in step S104 may be used as the output data as is. In other words, steps S105 and S106 may be omitted.

[0060] [Effects, etc.] As described above, the space design system 10 according to the first aspect of this embodiment is a space design system that outputs support information for designing an environment in a space used by a user, consisting of a combination of at least one element of lighting, video, and sound, and one or more other elements that are the same or different from the one element, and is equipped with a memory unit 12 that stores a plurality of sensory structure models that show the correlation between the strength of each combination, including at least one of the sensory values ​​of the degree of fatigue reduction, the degree of social activity, the degree of vitality improvement, the degree of creativity improvement, and the degree of concentration improvement felt by the user in the environment, with respect to the parameters of at least one element that constitutes the environment and the parameters of the other elements, and that have different correlations for each usage scenario of the space by the user; an input unit 11 that accepts input of usage scenarios; and a calculation unit 13 that uses a sensory structure model corresponding to the input usage scenario from the plurality of sensory structure models stored in the memory unit 12, and outputs as support information the strength of each of the sensory values ​​in the correlation shown in the sensory structure model in correspondence with the numerical value of the parameter of at least one element and the numerical value of the parameter of the other elements.

[0061] Such a space design system 10 can output support information by correlating the strength of each perceptual value with the numerical value of the parameter of at least one element and the numerical value of the parameter of other elements. The support information indicates the correspondence between the strength of each perceptual value in an appropriate perceptual structure model according to the usage scene and the numerical value of the parameter of at least one element and the numerical value of the parameter of other elements. Therefore, when designing a space to impart appropriate perceptual value, such correspondence can be used as an index for determining how to set the numerical value of the parameter of at least one element and the numerical value of the parameter of other elements. Therefore, it is possible to design a space more appropriately based on such an index.

[0062] Furthermore, for example, the space design system 10 according to the second aspect is the space design system 10 according to the first aspect, and the calculation unit 13 uses an affective structure model according to the input usage scene, and outputs as support information the numerical values ​​of the parameters of at least one element and the numerical values ​​of the parameters of other elements, by corresponding the respective strengths of the affective values ​​extracted from the correlations shown in the affective structure model using the filter conditions for the respective strengths of the affective values.

[0063] According to this, by extracting using filter conditions for the strength of each of the perceptual values ​​for specifying an appropriate perceptual value, when designing a space for giving such an appropriate perceptual value, it can be used as an index for determining how to set the numerical value of the parameter of at least one element and the numerical value of the parameter of another element. Therefore, it becomes possible to design a space more appropriately based on such an index.

[0064] Furthermore, for example, the space design system 10 according to the third aspect is the space design system 10 described in the second aspect, and the filter condition is that the value indicating the strength of each individual affective value in the combination is within a predetermined percentage from the top, or is equal to or greater than a threshold value.

[0065] According to this, the filter condition can be that the value indicating the strength of each individual affective value in the combination is within a predetermined percentage from the top, or is equal to or greater than a threshold value.

[0066] Furthermore, for example, a space design system 10 according to a fourth aspect is the space design system 10 according to the second aspect, and the filter condition is that the value indicating the strength of each individual perceptual value in the combination is maximum.

[0067] According to this, the filter condition can be that the value indicating the strength of each individual affective value in the combination is the largest.

[0068] Furthermore, for example, the space design system 10 according to the fifth aspect is a space design system 10 according to any one of the second aspects, and the filter condition is that the total value of the values ​​indicating the strength of each of the affective values ​​in the combination is within a predetermined percentage from the top, or is equal to or greater than a threshold value.

[0069] According to this, the filtering condition can be that the total value of the values ​​indicating the strength of each of the affective values ​​in the combination is within a predetermined percentage from the top, or is equal to or greater than a threshold value.

[0070] Furthermore, for example, the space design system 10 according to the sixth aspect is the space design system 10 according to any one of the second aspects, and the filter condition is that the total value of the values ​​indicating the strength of each of the affective values ​​in the combination is the largest.

[0071] According to this, the maximum total value of the values ​​indicating the strength of each of the affective values ​​in the combination can be used as a filter condition.

[0072] Furthermore, for example, a space design system 10 according to a seventh aspect is a space design system 10 according to any one of the second aspects, in which the input unit 11 further receives input of a prioritized perceptual value among the perceptual values, and the filter condition is that, among the individual perceptual values ​​in the combination, the value indicating the strength of the input prioritized perceptual value is within a predetermined percentage from the top, or is equal to or greater than a threshold value.

[0073] According to this, the filter condition can be that, among the individual affective values ​​in the combination, the value indicating the strength of the input prioritized affective value is within a predetermined percentage from the top, or is equal to or greater than a threshold value.

[0074] Furthermore, for example, the space design system 10 according to the eighth aspect is the space design system 10 according to any one of the second aspects, in which the input unit 11 further receives input of a prioritized perceptual value among the perceptual values, and the filter condition is that the value indicating the strength of the input prioritized perceptual value is the largest among the individual perceptual values ​​in the combination.

[0075] According to this, it is possible to use, as a filter condition, that the value indicating the strength of the input prioritized affective value is the largest among the individual affective values ​​in the combination.

[0076] Furthermore, for example, the space design system 10 according to the ninth aspect is a space design system 10 according to any one of the second aspects, in which each usage scene is associated with an affective value that takes priority in that usage scene from among the affective values, and the filter condition is that, among the individual affective values ​​in the combination, the value indicating the strength of the affective value that takes priority in that usage scene is within a predetermined percentage from the top, or is above a threshold value.

[0077] According to this, the filter condition can be that, among the individual affective values ​​in the combination, the value indicating the strength of the affective value prioritized in the usage scene is within a predetermined percentage from the top, or is equal to or greater than a threshold value.

[0078] Furthermore, for example, the space design system 10 according to the tenth aspect is a space design system 10 according to any one of the second aspects, in which each usage scene is associated with an affective value that takes priority in that usage scene among the affective values, and the filter condition is that the value indicating the strength of the affective value that takes priority in that usage scene among the individual affective values ​​in the combination is the largest.

[0079] According to this, it is possible to use, as a filter condition, that the value indicating the strength of the perceptual value prioritized in the usage scene among the individual perceptual values ​​in the combination is the largest.

[0080] Furthermore, for example, a space design system 10 according to an eleventh aspect is a space design system 10 according to any one of the second to tenth aspects, wherein the input unit 11 further accepts input of constraint conditions for at least one of the numerical values ​​of the parameters of at least one element and the numerical values ​​of the parameters of other elements, and the filter conditions include that the parameters of at least one element and the parameters of the other elements are within the constraint conditions.

[0081] According to this, the filter condition can be that the parameters of at least one element and the parameters of other elements are within the constraint conditions.

[0082] Furthermore, for example, a space design method according to a twelfth aspect is a space design method that is executed by a computer and outputs support information for designing an environment in a space used by a user, the environment being a combination of at least one element of lighting, video, and sound, and one or more other elements that may be the same as or different from the one element, and the support information includes at least one of the affective values ​​of the degree of fatigue reduction, the degree of interaction activity, the degree of vitality improvement, the degree of creativity improvement, and the degree of concentration improvement that the user feels in the environment, for a parameter of at least one element that constitutes the environment and a parameter of the other elements. The method includes a step (S101) of reading out from the storage unit 12 a plurality of sensory structure models which are sensory structure models showing correlations between the strengths of the sensory values ​​and which have different correlations for different usage scenarios of the space by the user; a step (S102) of accepting input of the usage scenario; and a step (S104) of using a sensory structure model corresponding to the input usage scenario from among the plurality of sensory structure models stored in the storage unit 12, corresponding the strengths of the sensory values ​​in the correlations shown in the sensory structure model to the numerical values ​​of the parameters of at least one element and the numerical values ​​of the parameters of other elements, and outputting them as support information.

[0083] This makes it possible to achieve the same effects as those of the space design system 10 described above.

[0084] Furthermore, for example, a program according to a thirteenth aspect is a program for causing a computer to execute the space design method described above.

[0085] This makes it possible to achieve the same effects as those of the space design system 10 described above using a computer.
