Although this is Type 1 Basic Research, the shift to Type 2 Basic Research becomes difficult if the human understanding is pursued excessively. It is necessary to clarify how the human function under study will be used and to synthesize the research scenario necessary for that purpose.In the example of the R&D for well-fitting eyeglass frames by Mochimaru and Kouchi, the objective is to provide glass frames that fit each individual, and the technology was developed to help select the frame design that the customer prefers.[16] Type 1 Basic Research involves the development of shape design technology to formulate the glass frame that matches the head shape, and the elemental technologies necessary to apply this to the user purchasing the glasses are selected, and the technologies are integrated. The feature of this research is the development of the 3D shape model (homologous head model) that could be used for simple measurement, pattern categorization of the shape, and the perceptual evaluation. The overall goal was achieved efficiently. Therefore, the overall scenario is the synthesis by “strategic selection type + breakthrough type.” In fact, if the breakthrough technology does not occur, the efficiency of the synthesis becomes poor, and the research may stall. The development of the core technology as the breakthrough technology imparts great power to Type 2 Basic Research.In the research on accessible design for the auditory signal that is compatible with the auditory function of the senior citizens by Kurakata and Sagawa,[17] it was important to determine the percentage of the elderly who can hear the auditory signal. Therefore, understanding the human auditory function precisely is not necessary, but the understanding of the distribution of the differences among people is important. This thinking was adapted to the understanding of the condition (auditory condition) at home where the alarm will actually be used. The sounds of the kitchen sink and television that may interfere with the auditory signal were measured, and by knowing the sound distribution, they were able to determine the sound volume that could be heard by the elderly. The property of the living environment must be understood to actually adapt the technology to the life scenes, and such study is necessary for the strategic selection type synthesis (Fig. 4).The setting of the research scenario is necessary to understand how the human properties can lead to the product design. In the example of the research on eyeglass frames, the scenario taken was to install a device that allows simple shape measurement and style recommendation at the stores, to enable the selection of a frame that matches the individual. On the other hand, as an example of accessible design, there is the scenario where the industrial standard is employed as the tool to be reflected in the product design. If the industrial standard is referred to, product design for the elderly can easily be realized. Also, in the research for providing moving images that do not cause visually induced motion sickness (VIMS) by Ujike,[18] initially the industrial standardization was attempted, but the researchers also constructed the image evaluation system that incorporated the VIMS property that was found in the Type 1 Basic Research. This system was to be used by the filmmakers to learn the effects the images might have on the viewers, and corrections were to be made if necessary. The author conducted the elemental researches necessary to construct the tool that could be used by the filmmakers, and this can be considered strategic Fig. 4 Strategic selection type synthesis in the life science (human technology) field• Perceptual impression of the face presented by eyeglass frame for each head shape• Noise in living environment where the electrical appliances are used• Conditions of viewing such as display size and viewing distance• 3D measurement of head shape• Clarification of changes in auditoryfunction due to aging• Clarification of the relationship between VIMS and image motion• Parameterization and categorization of head shape• Changes in auditory function due to aging• Pattern of image motion that induces sickness• Head homology model that allows expression of various forms and simple measurement method• Hearing range database for the elderly• Model for predicting VIMS• Eyeglass that fits the face• Electrical appliance with alarm that can be heard by the elderly• Movies and games with comfortable images that do not cause sicknessProduct that is compatible with human functionsExecution of R&DProcess of synthesizing of research scenarioCondition setduring themeasurement ofhuman functionsIdentification of environment andcondition of product useMeasurementof propertyof product useenvironmentSpecific items andnecessary precision ofmeasurement of humanfunctions incorporatedinto the toolConsideration of human functions needed for tool constructionTechnology to simplify the use of toolsConsideration of design tool that matches the product designHuman functions researchVarious human functions needed for tool and elemental technology groupModeled humanproperties, database tools• Measurements of customers’ head shape done at the store to select eyeglass type• Design by referring to the industrial standard of alarms• Areas of image that cause discomfort are automatically extracted and correctedProduct design considering the human functions
