中文摘要 | 本研究以視障者為對象(36位視障高中生,男22人、女14人;年齡15-22歲),探討現行流通之硬幣的可觸辨性,並評估新版50元(NT50')與20元(NT20)硬幣之盲人點字(braille)設計的效果。研究包含二種實驗:實驗一為硬幣觸辨測試,主要在瞭解硬幣間之觸辨錯誤率;實驗二為硬幣盲人點字效果測試,其旨在探討新版50元與20元硬幣之盲人點字設計效果;另外,配合視障者師生實地訪談,透過與啟明學校師生之面對面實地討論,藉以瞭解視障者觸辨硬幣之行為與其反應。研究結果(1)現行流通之20元與舊10元(NT10)硬幣辨識錯誤最高(44%與36%);(2)新50元與20元硬幣之配對(NT50'/NT20),由於二者設計參數相似,使得其辨識錯誤率高達15.3%,其次為20元與舊10元配對(NT20/NT10),錯誤率為12.5%;(3)20元硬幣之盲人點字設計,其可觸辨效果優於1996年發行之新50元硬幣,但二者點字被視障者採用做為觸辨判斷依據比率偏低(28%);(4)各硬幣配對間之直徑比應大於1.18、或厚度比應大於1.20、或直徑比與厚度比之乘積應大於1.42,方可保有較高之觸辨效果。 |
英文摘要 | Improper coin design affect not only the daily convenience, but also induce the lost due to discriminate error, even cause strife, especially affected the visual disabled person even more. This study tested the tactile discriminability of the existing Taiwanese coin system by the visually-handicapped and the usability of Braille on the new version of NT (New Taiwan) $50 coins released in 1996 and NT20 coins released in 2001 were evaluated. The first test of this study is the touch discriminability test of the coins, to analysis the error rate of touch discriminability of the new coins, then, a Braille effect of the new coins was tested for the visual disabled person. Further more, the teachers and students of the Chi-Ming School (A skill training school for the visual disabled person of Taiwan) were interviewed to analysis the preferable discriminability design factors. This study finds that: (1) The highest error rate occurs between the new NT20 and old NT10 coins (44% and 36% of error rate respectively). (2) Due to the similarity of coin design, the highest error rates occurs in the pair of new NT50/NT20 (with error rate of 15.3%), then followed by the new NT20/Old NT10 pair (12.5% of error rate). (3) The Braille discriminability of the new NT20 design is superior than the NT50 design, but their discriminability acceptance rate by the visual disabled is still low (28%). (4) To improve the touch discriminability of the coins system, this study suggest that the diameter ration should be larger than 1.18 between similar coin pairs, the thickness ratio should be larger than 1.20, or the multiple of the diameter ratio and the thickness ration should be larger than 1.42 for a better touch discriminability of the new coins design. |
