盲文

盲人使用的文字

AI overview

I don't have sufficient context to write an accurate overview. The provided caption only mentions a Braille dashboard in an elevator as an example of accessibility, but doesn't explain what Braille script actually is or why it matters. To write an accurate, fact-based overview as requested, I would need more substantive source material about Braille itself.

盲文（法語：Braille）又稱点字、盲字、凸字，是盲人使用的文字，由法國人路易·布萊葉發明，透過點字板、點字打字機、點字打印機等在紙張上製作出不同組合的凸點而組成。盲文的基本單位是長方形的盲符，有位置固定的六個點，每個點可以凸出或不凸出，形成64種可能，而全部不凸出不能表示實際含義，所以通常認為只有63種。六個點的分布是左右兩行，上中下三層。如圖所示，左行自上而下稱為1、2、3點，右行自上而下稱為4、5、6點。在電腦的使用範疇內，盲人可以配合點字顯示機將螢幕上的文字即時轉化成點字；而為了能表達ASCII的所有符號，故有增至八點的點字產生。
