However, attracting users is not only a matter of function and price. “Kansei” quality, which appeals to users’ feelings and needs holistically, is also important. To improve kansei quality, we need to understand the criteria users employ in determining attractiveness. New values are created constantly with the times, and these values are becoming increasingly more diverse. In meeting these values it is not enough to merely increase our product lineup and have customers choose from among them, but to propose products that fit each user’s values based on a precise understanding of them. In this study we focused on the “feeling of quality,” one aspect of kansei quality, and devised an evaluation axis for it based on vehicle bench-marking. We also researched preferred images for car interior products within groups that had been classified by preference tendencies and values in subjective experiments. In this report we introduce some case examples. *1 *2 *3 *4 ࢹࢨࣥ⏬㒊 ⏬㛤Ⓨᐊ ၟရ㛤Ⓨ㒊 ࣎ࢹ࣮㛤Ⓨᐊ ࢹࢨࣥ⏬㒊 ⏬㛤Ⓨᐊ ࢹࢨࣥ⏬㒊 ⏬㛤Ⓨᐊ 18 内装製品に求められる質感調査 㸯㸬ࡣࡌࡵ 㸰㸫㸰㸬ホ౯㍈ࡢᢳฟ ♫ෆࡢࢹࢨࢼ࣮㌴୧ࡗ࡚ࡶࡽ࠸㸪㉁ឤ ࡀ㧗ࡃឤࡌࡿ㸪పࡃឤࡌࡿ㒊ࡑࡢ⌮⏤ࡢ⪺ࡁ ྲྀࡾㄪᰝࢆᐇࡋࡓ㸬᭦ᢳฟࡉࢀࡓ࣮࣡ࢻࢆᒙ ูࡋ㸪௨ୗࡢ㸲ࡘࡢ࣮࣮࢟࣡ࢻ㸦ホ౯㍈㸧ࢆᑟࡁ ࡔࡋࡓ㸬 㸯㸧࣓ࣜࣁࣜ㸦ࢥࣥࢺࣛࢫࢺࢆࡅࡿ㸧 Ⰽ㸪ࢶࣖ㸪⣲ᮦ࡞㸪㞄ࡾྜ࠺㒊ရࢥࣥࢺ ࣛࢫࢺࢆࡅࡿࡇࡼࡾಶࠎࡢ㒊ရࡢ≉ᚩࡀ 㝿❧ࡕ㸪㉁ឤࡀࡼࡾ㧗ࡃឤࡌࡽࢀࡿ㸦ᅗ㸫㸰㸧㸬 ㏆ᖺ㸪㉮⾜ᛶ⬟࣭Ᏻᛶ࣭౽ᛶຍ࠼㸪࣮ࣘ ࢨ࣮ࡢ౯್ほ࣭ឤᛶッ࠼ࡿၟရࡢ⏬㛤Ⓨࡀ㔜 せ࡞ࡗ࡚ࡁ࡚࠸ࡿ㸬≉⮬ື㌴ࡢෆࡣ┤᥋ࣘ ࣮ࢨ࣮ࡀゐࢀࡿᶵࡀከࡃ㸪ࡑࡢ㔜せᛶࡣ᭦㧗 ࡲࡗ࡚࠸ࡃ⪃࠼ࡽࢀࡿ㸬 ඛࡢ⥲ㄝ࡛ࡶ㏙ࡽࢀ࡚࠸ࡿࡼ࠺ேࡢ౯್ほ ࡣከᵝ࡛࠶ࡾ㸪᭦௦ࡶᖖ᪂ࡋ࠸౯್ ほࡀ⏕ࡲࢀ࡚࠸ࡿ㸬ᡃࠎ㒊ရ࣓࣮࣮࢝ࡶ࣮ࣘࢨ࣮ ࡢ౯್ほᛂࡌࡓឤᛶッ࠼ࡿᵝࢆ〇ရᢡࡾ ㎸ࡳ㸪㨩ຊ࠶ࡿၟရࢆᥦ౪ࡍࡿࡇࡀồࡵࡽࢀ࡚ ࡁ࡚࠸ࡿ㸬≉㸪㍍⮬ື㌴㸪ࢥࣥࣃࢡࢺࢡࣛࢫࡢ ⮬ື㌴ෆࡢ㉁ឤࡣ㠀ᖖ㧗ࡲࡗ࡚ࡁ࡚࠸ࡿࡀ㸪 ࣮ࣘࢨ࣮ࡢồࡵࡿ㉁ឤࡸ㸪࠺࠸ࡗࡓどⅬ࡛㉁ឤ ࢆホ౯ࡋ࡚࠸ࡿࡢࡣ᫂ࡽ࡞ࡗ࡚࠸࡞࠸㸬 ᅇ㸪⮬ື㌴ࡢෆࡽཷࡅࡿ㉁ឤࡘ࠸࡚ឤ ᛶᕤᏛᡭἲࢆ⏝࠸࡚ゎᯒࡋ㸪࣮ࣘࢨ࣮ࡀ͆㉁ឤࡀ 㧗࠸͇ឤࡌࡿุ᩿ᇶ‽㸻ホ౯㍈ࢆᢳฟࡋ㸪᭦ ౯್ほᇶ࡙࠸ࡓ࣮ࣘࢨ࣮ࡢᒙูࡑࢀࡒࢀࡢႴ ዲ࣓࣮ࢪࢆᢳฟࡋࡓࡢ࡛ሗ࿌ࡍࡿ㸬 ᅗ㸫㸰 ࣓ࣜࣁࣜ㸦ࢥࣥࢺࣛࢫࢺࢆࡅࡿ㸧 㸰㸧⣲ᮦ㐀ࡾ 㸦ࣇ࢛࣒ࣝࢸࢡࢫࢳࣕࡢ࣓࣮ࢪࢆྜࢃࡏࡿ㸧 ぢࡓ┠ࡀ㌾ࡽࡑ࠺࡞⣲ᮦ㸦ࢸࢡࢫࢳࣕ㸧ࡣ ㌾ࡽࡑ࠺࡞᩿㠃ᙧ≧ࡍࡿ࡞㸪ࣇ࢛࣒ࣝ ࢸࢡࢫࢳࣕࡢ࣓࣮ࢪࢆྜࢃࡏࡿࡇ࡛㸪͆ᮏ ≀ឤ͇ࢆ㐃ࡋ㸪㉁ឤࡀ㧗ࡃឤࡌࡿ㸦ᅗ㸫㸱㸧㸬 㸰㸬͆㉁ឤ͇ࡢホ౯㍈ ㉁ឤࡢホ౯㍈ࢆᢳฟࡍࡿࡓࡵ㸪㉁ឤࡀ㧗࠸ゝ ࢃࢀ࡚࠸ࡿࢥࣥࣃࢡࢺ࣮࢝㸦Ḣᕞ㌴㸪ᅜ⏘㌴㸧 ࡘ࠸࡚ࣥࢣ࣮ࢺࢆᐇࡋࡓ㸬 㸰㸫㸯㸬ㄪᰝ㌴✀ ㄪᰝᑐ㇟ࡋ࡚Ḣᕞ㌴㸲ྎᅜ⏘㌴㸲ྎࢆ㑅ᐃ ࡋࡓ㸦ᅗ㸫㸯㸧㸬 ᅗ㸫㸱 ⣲ᮦ㐀ࡾ 㸱㸧⣲ᮦࡢ㨩ࡏ᪉ 㸦⣲ᮦࡢⰋࡉࢆ᭱㝈Ⓨࡉࡏࡿ㸧 ࣆࣀࣈࣛࢵࢡࡸ࣓ࢵ࢟ຍ㣭࡞ࢶࣖࢆ≉ᚩ ࡋࡓຍ㣭ࡣ㸪ගࡢᙜࡓࡾ᪉ࡸᑕࢆ⪃៖ࡋࡓᙧ≧㸪 㓄⨨ࡍࡿࡇ࡛㸪ࡑࡢ≉ᚩࢆ᭱㝈άࡍࡇ ࡀ࡛ࡁ㸪㉁ឤࡀ㧗ࡃឤࡌࡿ㸦ᅗ㸫㸲㸧㸬 ᅗ㸫㸯 ㄪᰝ㌴୧ 19 内装製品に求められる質感調査 㸱㸫㸯㸬ホ౯ࢧࣥࣉࣝ ᐇ㦂⏝ࢧࣥࣉࣝࡋ࡚㸪ࣥࢫࢺ࣓ࣝࣥࢺࣃࢿ ࣝࢆ࣓࣮ࢪࡋࡓ㠉ࢩ࣎㒊㸩࣮ࣔࣝ㸩ࣃࢿࣝࡢ㸱 㒊ရᵓᡂࡢࢧࣥࣉࣝࢆస〇ࡋࡓ㸦ᅗ㸫㸳㸧㸬ホ౯ ࡢࡓࡵ㸪㞄ࡾྜ࠺㒊ရࡢⰍ㸪ࢶࣖࡢ⤌ࡳྜࢃࡏ ࢆኚ࠼ࡓࡶࡢࢆ㸶Ỉ‽స〇ࡋࡓ㸬ࢧࣥࣉࣝỈ‽ ࢆ⾲㸫㸰♧ࡍ㸬 㠉ࢩ࣎㒊 ࣮ࣔࣝ ᅗ㸫㸲 ⣲ᮦࡢ㨩ࡏ᪉ 㸲㸧ຍ㣭ࡢ࠸᪉㸦ᶵ⬟࣭᧯స㒊ࢆᙉㄪࡍࡿ㸧 ࢫࢸࣜࣥࢢࡸࣞࢪࢫࢱ࣮࡞㸪ᶵ⬟ࢆ᭷ࡋ ࡚࠸ࡿ㒊ရࡣࢡࢭࣥࢺ࡞ࡿຍ㣭ࢆࡍࡇ ࡛㸪ࡑࡢᶵ⬟ᛶࡀᙉㄪࡉࢀ㸪యࡢ㉁ឤࡀ㧗 ࡃឤࡌࡿ㸬≉᧯స㒊ࡣぢࡓࡾ㸪ᡭࡀゐࢀࡓ ࡾࡍࡿᶵࡀከ࠸ࡓࡵ㸪ຠᯝⓗ࡛࠶ࡿ⪃࠼ࡽ ࢀࡿ㸦⾲㸫㸯㸧㸬 ࣃࢿࣝ ᅗ㸫㸳 ᐇ㦂ࢧࣥࣉࣝ ⾲㸫㸰 ࢧࣥࣉࣝỈ‽ ⾲㸫㸯 ຍ㣭ࡢ࠸᪉ 㸱㸫㸰㸬Ⴔዲࡼࡿࢢ࣮ࣝࣉศࡅ ⿕㦂⪅ᑐࡋ࡚㸶✀㢮ࡢࢧࣥࣉࣝࢆ୍ࡘࡎࡘ ᥦ♧ࡋ㸪ࡑࢀࡒࢀࡘ࠸࡚ࠕ㉁ឤࡢ㧗ࡉࠖࡘ࠸࡚ 0㹼100Ⅼ࡛ホ౯ࡋ࡚ࡶࡽࡗࡓ㸦ᅗ㸫㸴㸧㸬ࢧࣥࣉ ࣝࡅࡽࢀࡓⅬᩘࡽࢡࣛࢫࢱ࣮ศᯒࢆ⾜࠸㸪 ⿕㦂⪅ࡢࢢ࣮ࣝࣉศࡅࢆ⾜ࡗࡓ㸬⿕㦂⪅ᩘࡣ18ṓ 㹼86ṓࡢ⏨ዪྜࢃࡏ࡚136ே࡛࠶ࡿ㸬 㸱㸬౯್ほࡼࡿ࣮ࣘࢨ࣮ศ㢮 ➨㸰❶࡛㏙ࡓ㉁ឤࡢホ౯㍈ࢆ⪃៖ࡋࡓࣥࢸ ࣜࢹࢨࣥࢆ⾜࠺ࡇ࡛㨩ຊⓗ࡞ၟရࢆᥦ౪࡛ ࡁࡿ⪃࠼ࡽࢀࡿ㸬ࡋࡋ࣮ࣘࢨ࣮ࡢ౯್ほ࣭Ⴔ ዲࡣከᵝࡋ࡚ࡁ࡚࠾ࡾ㸪㸲ࡘࡢホ౯㍈ࡢ᪉ྥᛶ ࡸ㔜せᗘࡣ␗࡞ࡿࡇࡀ⪃࠼ࡽࢀࡿ㸬 ࡇࡇ࡛ࡣᢳฟࡉࢀࡓホ౯㍈ࡢ୰ࡽ㸪ࠕ࣓ࣜࣁ ࣜࠖࡘ࠸࡚ὀ┠ࡋ㸪࣮ࣘࢨ࣮ࡢ౯್ほ࣭Ⴔዲࡢ 㐪࠸ࡼࡿࠕ࣓ࣜࣁࣜࠖࡢឤࡌ᪉ࡢ㐪࠸ࡘ࠸࡚ ㄪᰝࡋࡓࡢ࡛ࡑࡢෆᐜࡘ࠸࡚㏙ࡿ㸬 ᅗ㸫㸴 ホ౯㢼ᬒ 20 内装製品に求められる質感調査 ࡢࢧࣥࣉࣝࡢࡼ࠺࡞࣓࣮ࢪࢆឤࡌࡓࡀ ࢃࡿ㸬ࡇࡢ⤖ᯝࡽ㸪⿕㦂⪅ࢢ࣮ࣝࣉCࡣ࣓ࣜ ࣁࣜࡀᑡ࡞ࡃ㸪ẚ㍑ⓗⴠࡕ╔࠸ࡓ㟼ⓗ࣓࣮ࢪࡢ ᑐ㇟ࢆዲࡴࡇࡀศࡗࡓ㸬 ҽᴾ 䐥 䐦 ⋁⋟⊳⋆⋑⊰⊹ ᩺ႎ έᡶႎ ᝍᓙ ɥԼ ڤⅼ ⋝⊳⋚⋅⋟ ᛦ᭗ⅳ ⋍⊬⊱⋐⋚ ኮٟႎ ˡወႎ 䐡 ᓳ←ბⅼ 䐤 ⋓⋙⋋⋙ⅻⅱ↺ ⊾⋏⋠⊱⋄⊩ 䐣 ѣႎ ⊷⊽⋟⊮⊲⋚ 䐢 䐟 ᅗ㸫㸵 ࢡࣛࢫࢱ࣮ศᯒ⤖ᯝ 䐠 ᠉ࣛᴾ ᅗ㸫㸷 ᩘ㔞Ϫ㢮ศᯒ⤖ᯝ ࢡࣛࢫࢱ࣮ศᯒࡢ⤖ᯝ㸪ࢧࣥࣉࣝࡢ㉁ឤᑐࡍ ࡿឤࡌ᪉ࡀ㸲ࡘࡢࢢ࣮ࣝࣉศࡅࡽࢀࡿࡇࡀࢃ ࡗࡓ㸦ᅗ㸫㸵㸧㸬ࢢ࣮ࣝࣉA㸪Bࡣ㞄ࡾྜ࠺㒊ရ ࡢࢥࣥࢺࣛࢫࢺࡀ࠶ࡿࡇࢆዲࡴഴྥ࠶ࡿࡢ ᑐࡋ㸪ࢢ࣮ࣝࣉC㸪Dࡣࢥࣥࢺࣛࢫࢺࡀ࠶ࡲࡾ࡞࠸ ࡇࢆዲࡴഴྥ࠶ࡗࡓ㸬 ࡑࡢࢢ࣮ࣝࣉࡶྠᵝศᯒࢆᐇࡋ㸪Ⴔዲ ࣓࣮ࢪࢆᢳฟࡋࡓ㸬ࡉࡽ㸪⿕㦂⪅ᒓᛶࡽ㸪ࢢ ࣮ࣝࣉࡢ୰ᚰ࡞ࡿ࣮ࣘࢨ࣮ᒙࢆࡾฟࡋ㸪ྛࣘ ࣮ࢨ࣮ᒙ㉁ឤồࡵࡿ࣓࣮ࢪࢆ⾲㸫㸱ࡲ ࡵࡓ㸬 ⾲㸫㸱 ⤖ᯝࡲࡵ 㸱㸫㸱㸬㉁ឤồࡵࡿ࣓࣮ࢪ ㉁ឤࡢឤࡌ᪉࡛ศ㢮ࡉࢀࡓ࣮ࣘࢨ࣮ᒙࡀồࡵࡿ ࣓࣮ࢪࢆㄪᰝࡍࡿࡓࡵ㸪ྛࢧࣥࣉࣝࡽཷࡅࡿ ࣓࣮ࢪࢆࣥࢣ࣮ࢺ࡚ᢳฟࡋࡓ㸬⏝ࡋࡓ ࣥࢣ࣮ࢺ⏝⣬ࡢ୍㒊ࢆᅗ㸫㸶♧ࡍ㸬 ᅗ㸫㸶 ࣥࢣ࣮ࢺ⏝⣬ ࣥࢣ࣮ࢺ⤖ᯝࢆᩘ㔞Ϫ㢮࡛ศᯒࡋ㸪㉁ឤ ồࡵࡿ࣓࣮ࢪࢆᅗ㸫㸷ࡢࡼ࠺ྍどࡋࡓ㸬 ࡋ࡚ᅗ㸫㸷ࢢ࣮ࣝࣉCࡢ⤖ᯝࢆ♧ࡍ㸬ࢢࣛࣇ ࡢ㍈ࡣ⨨ࡉࢀࡓᙧᐜモࡽ㸪⦪㍈ࢆ㔜ཌ㸫㍍ᛌ㸪 ᶓ㍈ࢆ㟼ⓗ㸫ືⓗࡋࡓ㸬ྛࢧࣥࣉࣝࡢ⨨ࡽ㸪 21 内装製品に求められる質感調査 㸲㸬ࡲࡵ ᅇ㸪ࠕ࣓ࣜࣁࣜࠖ╔┠ࡋ࡚࣮ࣘࢨ࣮ࡢ㉁ឤ ࡢឤࡌ᪉ࡼࡿศ㢮ࡑࢀࡒࢀࡢዲࡴ࣓࣮ࢪࢆ ᢳฟࡋࡓ㸬ᮏ⤖ᯝࡽ࣮ࣘࢨ࣮ࡢ౯್ほู㒊ရ 㛫ࡢࢥࣥࢺࣛࢫࢺࡢᵝࢆኚ࠼ࡿࡇ࡛㸪ࡼࡾࣘ ࣮ࢨ࣮ࡢႴዲྜࡗࡓၟရᵝࡢ୍㒊ࢆᥦ࡛ࡁ ࡿ⪃࠼࡚࠸ࡿ㸬 ᮏ⤖ᯝࡣࢥࣥࣃࢡࢺ࣮࢝ࡢෆࢆᑐ㇟ࡋࡓ㸪 ୍㒊ࡢ⤖ᯝ࡛࠶ࡾ㸪ࡑࡢࡢ㌴⣔㸪㒊㸪ṧࡗࡓ ホ౯㍈ࡘ࠸࡚ࡶㄪᰝࢆ⥆ࡅ㸪ࡼࡾ㨩ຊ࠶ࡿၟရ 㛤Ⓨ⧅ࡆ࡚࠸ࡁࡓ࠸⪃࠼࡚࠸ࡿ㸬 ⴭ ⪅ 㔝㑥⿱ டಇ㍜ ஂಖ༓✑ ᗈ℩ྜྷ୍ 22
