FIG. 10 is a diagram illustrating an example of information presented by a presentation unit. 10 is a flowchart showing a flow of information processing by an information processing device.

An example of an embodiment of the present disclosure will now be described with reference to the drawings. Note that the same reference numerals are used throughout the drawings to designate identical or equivalent components and parts. Also, the dimensional proportions in the drawings have been exaggerated for the sake of explanation and may differ from the actual proportions.

Figure 1 is a diagram showing an example configuration of an information processing device according to this embodiment. The information processing device 10 shown in Figure 1 is a device that visually presents information verbalized based on the five senses. In the information processing device 10, the CPU 11 functions as the acquisition unit 101 and the presentation unit 102. The storage 14 stores evaluation information acquired by the acquisition unit 101. The evaluation information is information in which the evaluation of an evaluation target has been verbalized. The evaluation information of an evaluation target is an evaluation of the five senses, such as the appearance, smell, taste, sound, and feel of the evaluation target.

The information processing device 10 has a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, and storage 14.

CPU 11 is a central processing unit that executes various programs and controls each component. That is, CPU 11 reads programs from ROM 12 or storage 14 and executes the programs using RAM 13 as a work area. CPU 11 controls the above components and performs various calculations in accordance with the programs recorded in ROM 12 or storage 14. In this embodiment, ROM 12 or storage 14 stores an information processing program that executes information processing that visually presents information verbalized based on the five senses about the evaluation of the evaluation target.

ROM 12 stores various programs and data. RAM 13 temporarily stores programs or data as a working area. Storage 14 is composed of a storage device such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or flash memory, and stores various programs, including the operating system, and various data.

When executing the above information processing program, the information processing device 10 uses the above hardware resources to realize various functions. The functional configuration realized by the information processing device 10 will be described below.

As shown in FIG. 1, the information processing device 10 has, as its functional components, an acquisition unit 101 and a presentation unit 102. Each functional component is realized by the CPU 11 reading and executing an information processing program stored in the ROM 12 or storage 14.

The acquisition unit 101 acquires feature quantities of the measurement data of the evaluation object and evaluation information that verbalizes the evaluation of the evaluation object. The evaluation object is, for example, an object whose appearance can be evaluated, such as a molded resin made by mixing pigments into plastic resin. The acquisition unit 101 then acquires, as feature quantities of the evaluation object, information such as L*a*b* values, gloss values, angle-dependent L*a*b* values, and spectral shape measured using a colorimeter, gloss meter, absorbance meter, etc. for the evaluation object.

In addition to appearance, the object of evaluation can also be something related to the five senses, such as smell, taste, sound, or touch. The object of evaluation can be either tangible or intangible.

The acquisition unit 101 further acquires evaluation information in which the evaluation of the evaluation object is verbalized. The evaluation information is the content of the evaluation made by the evaluator regarding the evaluation object. For example, when the evaluator evaluates the appearance, the evaluator may make evaluations such as "no gloss," "has a sense of depth," "is lonely," "has a strong blue tinge," and "is solid." The acquisition unit 101 associates the acquired feature quantities of the evaluation object with the evaluation information and stores them in the storage 14.

The evaluation information provided by the evaluator regarding the evaluation object may be "lonely" or "lacking a grainy feel," or may be an evaluation of the characteristics of the product in which the evaluation object is used. For example, the evaluation information provided may be that the object matches a specific vehicle model, or that it does not match a specific vehicle model. The evaluation information provided by the evaluator may also include categories. For example, the evaluation information provided by the evaluator may include comments regarding the color, such as bluish, intuitive comments such as "lonely" or "cold," or comments regarding the vehicle model or grade.

Figure 2 is a diagram showing an example of information stored in storage 14. Figure 2 shows how, for a sample to be evaluated whose appearance is to be evaluated, the feature values for that sample and the evaluation information for that sample are stored in association with each other. Figure 2 shows L* value and gloss value as examples of feature values, but other feature values may also be stored. Figure 2 also shows how the results of the appearance evaluations made by evaluators for each sample are stored.

The presentation unit 102 visually presents evaluation information in which the evaluation of the evaluation object is verbalized, based on the feature quantities of the measurement data of the evaluation object acquired by the acquisition unit 101. Specifically, the presentation unit 102 presents the evaluation information by mapping it onto a predetermined map, for example, a two-dimensional plane. The axis in this case is one of the feature quantities in the measurement data. For example, the evaluation information is presented on a two-dimensional plane with the horizontal axis representing the gross value and the vertical axis representing the L* value.

Figure 3 is a diagram showing an example of information presented by the presentation unit 102. Figure 3 is an example of a two-dimensional graph with, for example, gross value on the horizontal axis and, for example, L* value on the vertical axis. The presentation unit 102 can visually present evaluation information in which the evaluation of the evaluation target is verbalized, using information stored in the storage 14 that associates feature amounts with evaluation information for each sample.

By having the presentation unit 102 visually present the evaluation information as in the graph shown in Figure 3, material developers can refer to the evaluation information presented by the presentation unit 102 and identify areas that need to be changed in order to change the verbalized characteristics. For example, by referring to the evaluation information visually presented by the presentation unit 102, a material developer can understand that in order to make a material with a granite-like texture cool and advanced, it is necessary to increase the absorption rate of red wavelength light by 50%, decrease the total reflectance of light by 10%, and increase the scattering intensity by 20%.

The presentation unit 102 may propose and present the amount of change to be made to the feature quantity to be evaluated. For example, if the relationship between the material composition ratio and the parameters is known, the presentation unit 102 may present the change in the material composition ratio in addition to the change in the parameters.

When presenting evaluation information on a two-dimensional plane, the presentation unit 102 may also show a range of feature quantities that match a specific vehicle, as shown in FIG. 3. By showing a range of feature quantities that match a specific vehicle, the presentation unit 102 can present, for example, for a sample that does not match any vehicle, which parameters need to be changed and how to make it match a specific vehicle. In the example of FIG. 3, the presentation unit 102 can show that a useless prototype can become a sample that matches vehicle B by lowering the L* value.

When presenting evaluation information, if there are three or more features corresponding to the evaluation information, the presentation unit 103 may present the evaluation information in three-dimensional space in addition to presenting it on a two-dimensional plane.

Even when the evaluation subject is evaluating other sensory items, the information processing device 10 can similarly visually present the evaluation information. For example, if the evaluation subject is odor, the information processing device 10 acquires and associates the feature values obtained by evaluating the odor of the evaluation subject using a gas chromatograph with the verbalized evaluation results by the evaluator, and presents them on a two-dimensional plane.

For example, if the evaluation target is taste, the information processing device 10 acquires and associates the feature values obtained by evaluating the taste components of the evaluation target using a taste sensor with the verbalized evaluation results of the evaluator, and presents them on a two-dimensional plane.

For example, if the evaluation target is sound, the information processing device 10 acquires and associates the feature values obtained by evaluating the sound to be evaluated using frequency analysis with the verbalized evaluation results by the evaluator, and presents them on a two-dimensional plane.

For example, if the evaluation target is touch, the information processing device 10 acquires and associates the feature values obtained by evaluating the hardness, etc. of the evaluation target using a hardness sensor with the verbalized evaluation results by the evaluator, and presents them on a two-dimensional plane.

By having such a configuration, the information processing device 10 can visually present information about the evaluation of an evaluation object that has been verbalized based on the five senses, for example, on a two-dimensional plane. By having the information processing device 10 visually present information about the evaluation of an evaluation object that has been verbalized based on the five senses, it becomes easier to change the parameters of the evaluation object when designing the evaluation object.

Next, we will explain the operation of the information processing device 10.

Figure 4 is a flowchart showing an example of the flow of information processing by the information processing device 10. Information processing is performed by the CPU 11 reading an information processing program from the ROM 12 or storage 14, expanding it into the RAM 13, and executing it.

In step S101, the CPU 11 acquires feature quantities of the measurement data of the evaluation object and evaluation information that verbalizes the evaluation of the evaluation object. The evaluation object is, for example, an object whose appearance can be evaluated, such as a molded resin made by mixing pigments into plastic resin. For the evaluation object, information on the L*a*b* values, gloss values, angle-dependent L*a*b* values, and spectral shape is acquired as feature quantities of the evaluation object using a colorimeter, gloss meter, absorbance meter, etc.

Following step S101, in step S102, the CPU 11 visually presents the evaluation information acquired in step S101 based on the feature quantities also acquired in step S101. The CPU 11 presents the evaluation information on a predetermined map, for example, a two-dimensional plane. The axis in this case is one of the feature quantities in the measurement data. For example, the evaluation information is presented on a two-dimensional plane with the horizontal axis representing the gross value and the vertical axis representing the L* value.

By executing this processing, the information processing device 10 can visually present, for example, in two-dimensional space, information about the evaluation of an evaluation object that has been verbalized based on the five senses. By the information processing device 10 visually presenting information about the evaluation of an evaluation object that has been verbalized based on the five senses, it becomes easier to change the parameters of the evaluation object when designing the evaluation object.
