[0006] Therefore, an object of the present invention is to provide a simulation system that can reproduce the interior view of a room in which interior building materials and lighting devices are installed on a display device.

Therefore, the interior view of the room with the interior building materials and lighting devices installed can be reproduced on the display device, and the user can confirm the assumed view inside the room with the interior building materials and lighting devices installed according to the user's preference. In addition, since the view frequency can also be confirmed, it is easy to imagine the actual use of the room.

[0010] A preferred aspect is that the assumed view calculation unit calculates an assumed view at a position and direction specified by the user in the room.

[0011] A preferred aspect includes a satisfaction data acquisition unit that acquires satisfaction data including the user's satisfaction with each assumed visual field, and a proposed model calculation unit that calculates a proposed model in which interior building materials and lighting devices are combined so that the user's satisfaction with the assumed visual field is increased from the satisfaction data acquired by the satisfaction data acquisition unit.

[0030] (Room 100) The room 100 is a room assumed to be used by the user and targeted for simulation. As shown in FIG. 2, the room 100 is a space surrounded by wall surfaces 110a to 110f, and one or more pieces of furniture 111, a plurality of interior building materials 101, and one or more lighting devices 102 are arranged therein.

[0031] The furniture 111 is well-known and includes, for example, furniture such as desks, chairs, and electrical appliances such as televisions.

[0032] The first wall surface 110a is the ceiling surface that constitutes the ceiling of the room 100, to which one or more ceiling-side building materials 101a are attached, and the ceiling-side building materials 101a constitute at least a part of the outermost surface. The ceiling-side building materials 101a are not particularly limited as long as they are building materials for ceiling walls, and for example, wallpaper or the like can be used.

[0033] The second wall surface 110b is the floor surface that constitutes the floor of the room 100, to which one or more floor-side building materials 101b are attached, and the floor-side building materials 101b constitute at least a part of the outermost surface. The floor-side building materials 101b are not particularly limited as long as they are building materials for floor walls, and floor materials such as flooring materials can be used.

[0034] The wall surfaces 110c to 110f are the side wall surfaces that constitute the four walls of the room 100, to which one or more wall-side building materials 101c to 101f are attached, and the wall-side building materials 101c to 101f constitute at least a part of the outermost surface. The wall-side building materials 101c to 101f are not particularly limited as long as they are building materials for walls, and for example, wallpaper or the like can be used.

[0035] The lighting device 102 has a light source, irradiates light from the light source, and is a device that illuminates the interior of the room 100. The type of light source of the lighting device 102 is not particularly limited, and for example, LEDs, OLEDs, fluorescent lamps, krypton bulbs, reflector bulbs, halogen bulbs, etc. can be adopted. The type of lamp of the lighting device 102 is not particularly limited, and for example, ceiling lights, downlights, pendant lights, spotlights, bracket lights, stand lights, floor lights, duct rail lights, floor lights, chandeliers, exterior lights, indirect lighting, etc. can be adopted.

[0036] Next, the simulation operation of the simulation system 1 of the present embodiment will be described with reference to FIG. 3.

[0037] In the simulation operation of the present embodiment, first, room data including the position, floor plan, furniture 111, usage status, position of interior building materials 101, and position of lighting device 102 in the room 100 assumed by the user is input to the data input device 3, and the room data acquisition unit 10 acquires the room data via the data input unit 17 (step S1). Then, the room layout generation unit 11 creates the layout of the room 100 assumed by the user using the room data acquired by the room data acquisition unit 10 (step S2).

[0038] Subsequently, an input image 200 of interior lighting data shown in FIG. 4 is displayed on the display device 5, and the input of each item of the interior lighting data by the user is confirmed (step S3).

[0039] At this time, as shown in FIG. 4, the input image 200 has product input parts 201a to 201d for inputting data related to products such as product names and model numbers corresponding to the interior building materials 101a to 101f and the lighting device 102, priority input parts 202a to 202d for inputting their priorities, a decision button 203, and a cancel button 204. Each item of the product input parts 201a to 201d and the priority input parts 202a to 202d can input products and priorities by the data input device 3. Also, in the input image 200, priorities can be input according to a plurality of ranks. For example, in the input image 200 of FIG. 4, priorities can be ranked and input in three levels of A to C in order from the highest priority.

[0040] When the determination button 203 is pressed by the user and it is confirmed that the interior lighting data has been input (Yes in step S3), the interior lighting data acquisition unit 12 acquires the interior lighting data, and the assumed visual field calculation unit 13 calculates a plurality of assumed visual fields and the visual field frequencies at the assumed visual fields at the observation point O1 facing a specific direction at a specific position according to the priorities of each interior building material 101 and lighting device 102 (step S4). As shown in FIG. 5, the assumed visual field images 210 including the calculated assumed visual fields and visual field frequencies at the observation point O1 are respectively displayed on the display device 5 (step S5).

[0041] At this time, as shown in FIG. 5, the assumed visual field image 210 is provided with a room layout display unit 211 that displays the layout of the room 100 and the direction of the assumed visual field at the observation point O1, and a product-related display unit 212 that includes the product names or model numbers of each interior building material 101a to 101f and lighting device 102 that constitute the ceiling, wall, and floor displayed in the layout of the room 100, and a visual field frequency display unit 213 that includes the visual field frequency in the assumed visual field. In addition, as shown in FIG. 5, the product-related display unit 212 preferably includes the total cost of the interior building materials 101 and lighting devices 102 used in the layout of the room 100, and preferably includes data related to the electricity cost or electricity consumption of the lighting device 102 (for example, annual electricity cost, electricity cost per day, annual power consumption, power consumption per day).

[0042] In the present embodiment, the assumed visual field images 210 including the assumed visual fields and visual field frequencies calculated by the assumed visual field calculation unit 13 are respectively displayed every predetermined time T1. That is, each assumed visual field image 210 calculated by the assumed visual field calculation unit 13 transitions every predetermined time T1 like a digital photo frame. For example, it transitions from the assumed visual field image 210a of group G1 shown in FIG. 5 to the assumed visual field image 210b of group G2 in which some or all of the interior building materials 101 and lighting devices 102 are different from those of group G1 shown in FIG. 6, or from the assumed visual field image 210a of group G1 shown in FIG. 5 to the assumed visual field image 210c of group G1 in which the position and / or direction of the observation point O1 are different from those shown in FIG. 7. The specified time T1 is not particularly limited, but is preferably 1 second or more and 10 seconds or less.

[0043] In addition, in this embodiment, it is possible to move the position and direction of the observation point O1 in the room 100 to an arbitrary designated position and designated direction. At this time, the assumed field of view calculation unit 13 recalculates and calculates the assumed field of view and the field of view frequency at the observation point O1 designated by the user, and displays an assumed field of view image 210 including the calculated assumed field of view and the field of view frequency at the observation point O1 on the display device 5.

[0044] When all the assumed field of view images 210 are displayed, an input image 220 of satisfaction data shown in FIG. 8 is displayed on the display device 5, and the user's input of each item of satisfaction data is confirmed (step S6).

[0045] At this time, on the input image 220, data related to products such as product names and model numbers corresponding to each interior building material 101 and lighting device 102 that constitute the assumed field of view for each group are displayed. Further, the input image 220 has a selection button 221 and a satisfaction input unit 222 corresponding to each group, a determination button 223, a re-display button 224, and a cancel button 225, and the satisfaction can be input to the satisfaction input unit 222 by the data input device 3. On the input image 220, the satisfaction can be input by a plurality of ranks. For example, in the input image 220 of FIG. 8, the satisfaction can be ranked and input in three stages of A to C in order from the highest satisfaction.

[0046] In the input image 220 of this embodiment, for example, as shown in FIG. 8, by checking the selection button 221 corresponding to the group G1 and pressing the re-display button 224, the process transitions to the assumed field of view image 210 of the group G1 shown in FIG. 5, and when a predetermined time T2 elapses, the process transitions back to the input image 220. The predetermined time T2 is not particularly limited, but is preferably 1 second or more and 10 seconds or less.

[0047] In step S6, when the user presses the decision button 223 and it is confirmed that satisfaction data has been input (Yes in step S6), the proposed model calculation unit 16 calculates a proposed model according to the satisfaction of each assumed visual field (step S7). As shown in FIG. 9, a proposed model image 230 including the calculated proposed model is displayed on the display device 5 (step S8), and the simulation operation is terminated.

[0048] At this time, the proposed model calculation unit 16 can calculate a proposed model by, for example, reinforcement learning. The "reinforcement learning" mentioned here is a machine learning in which an agent, which is an acting entity in a certain environment, observes the current state, which is a parameter of the environment, and determines the action to be taken. The environment changes dynamically according to the agent's actions, and the agent is given a reward according to the change in the environment. The agent repeats this, and learns an action policy that can obtain the most rewards through a series of actions. As methods of reinforcement learning, for example, Q-learning, SARSA, Monte Carlo method, etc. can be used. The proposed model calculation unit 16 of the present embodiment sets rewards for each of the interior building materials 101a to 101f and the lighting device 102 based on the satisfaction of each assumed visual field, creates a plurality of combined models in which the interior building materials 101a to 101f and the lighting device 102 are combined, calculates the total of the rewards of each of the interior building materials 101a to 101f and the reward of the lighting device 102 constituting each combined model, and calculates the combined model with the largest total reward as the proposed model.

[0049] In step S3, when interior lighting data is not input (No in step S3) and the cancel button 204 is pressed (Yes in step S9), the simulation operation is terminated. On the other hand, in step S3, when interior lighting data is not input (No in step S3) and the cancel button 204 is not pressed (No in step S9), the process returns to step S3 again to confirm the input of the interior lighting data.

[0050] In step S6, if the satisfaction data for each assumed field of view is not input (No in step S6) and the cancel button 225 is pressed (Yes in step S10), the simulation operation is terminated. On the other hand, in step S6, if the satisfaction data for each assumed field of view is not input (No in step S6) and the cancel button 225 is not pressed (No in step S10), the process returns to step S6 to confirm the input of the satisfaction for each assumed field of view.

[0051] According to the simulation system 1 of the present embodiment, the combination of the assumed field of view of the user inside the room 100 and the view frequency corresponding to the assumed field of view is calculated according to the priorities of each interior building material 101 and the lighting device 102 selected by the user, and the combination of the assumed field of view of the user inside the room 100 and the view frequency corresponding to the assumed field of view is displayed on the display device 5. Therefore, the interior view of the room 100 equipped with the interior building material 101 and the lighting device 102 can be reproduced on the display device 5, and the user can confirm the assumed field of view inside the room 100 equipped with the interior building material 101 and the lighting device 102 based on the user's preference. In addition, since the view frequency can also be confirmed, it is easy to imagine the image when actually using the room 100.

[0052] According to the simulation system 1 of the present embodiment, since the assumed field of view calculation unit 13 calculates the assumed field of view in the specified direction at the observation point O1 specified by the user inside the room 100, it is easy for the user to imagine the situation inside the room 100.

[0053] According to the simulation system 1 of the present embodiment, it includes a satisfaction data acquisition unit 15 that acquires satisfaction data including the satisfaction of the user for each assumed field of view, and a proposed model calculation unit 16 that calculates a proposed model in which the interior building material 101 and the lighting device 102 are combined so that the satisfaction of the user with respect to the assumed field of view is increased from the satisfaction data acquired by the satisfaction data acquisition unit 15. Therefore, a proposed model that greatly reflects the user's preference that the user has not imagined can be proposed.

[0054] According to the simulation system 1 of the present embodiment, the proposed model calculation unit 16 assigns rewards to each of the interior building materials 101a to 101f and the lighting device 102 according to the satisfaction of the user with respect to each assumed field of view, creates a plurality of combined models by combining each of the interior building materials 101a to 101f and the lighting device 102, calculates the total of the rewards of the interior building materials 101a to 101f and the reward of the lighting device 102 that make up each combined model, and calculates the combined model with the largest total reward as the proposed model. Therefore, the user's preferences for each of the interior building materials 101a to 101f and the lighting device 102 are likely to be reflected in the proposed model.

[0055] According to the simulation system 1 of the present embodiment, the display device 5 displays while transitioning each assumed field of view and combination of assumed fields of view calculated by the assumed field of view calculation unit 13 every predetermined time T1, so that comparison in each assumed field of view is easy.

[0056] In the above-described embodiment, the proposed model calculation unit 16 sets rewards for each of the interior building materials 101a to 101f and the lighting device 102 based on the satisfaction of each assumed field of view, but the present invention is not limited to this. The proposed model calculation unit 16 may set a reward for the total cost of each of the interior building materials 101a to 101f and the lighting device 102, in addition to the rewards for each of the interior building materials 101a to 101f and the lighting device 102, based on the satisfaction of each assumed field of view. A reward may be set for the electricity cost of the lighting device 102, or a reward may be set for the amount of electricity of the lighting device 102. In these cases, the proposed model calculation unit 16 calculates the total of each reward in each combined model, and calculates the combined model with the largest total reward as the proposed model.

[0057] In the above-described embodiment, the calculation and the like of the simulation system 1 were performed by one computer 2, but the present invention is not limited to this. The calculation and the like of the simulation system 1 may be performed by a plurality of computers 2.

[0058] In the above-described embodiment, the assumed frequency was displayed as the assumed time per day, but the present invention is not limited thereto. For example, the assumed frequency may be displayed as the assumed ratio per day, or may be displayed as the assumed time per month.

[0059] In the above-described embodiment, the case where the room 100 includes one type of lighting device 102 has been described, but the present invention is not limited thereto. The room 100 may include two or more types of lighting devices 102.

[0060] In the above-described embodiment, the case where each of the interior building materials 101a to 101f in the room 100 is provided with one type has been described, but the present invention is not limited thereto. The room 100 may include two or more types of each of the interior building materials 101a to 101f.

[0061] In the above-described embodiment, the priorities of the interior building materials 101a to 101f and the lighting device 102 have been evaluated in three levels, but the present invention is not limited thereto. Each priority may be evaluated in two levels, or may be evaluated in four or more levels.

[0062] In the above-described embodiment, the satisfaction of each group has been evaluated in three levels, but the present invention is not limited thereto. The satisfaction of each group may be evaluated in two levels, or may be evaluated in four or more levels.

[0063] As long as the above-described embodiments are included in the technical scope of the present invention, each component can be freely replaced or added between the embodiments.
