翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Braille watch ： ウィキペディア英語版 Braille watch A braille watch is a portable timepiece used by the blind or visually impaired to tell time. It is used by touching the dial and noticing the embossments. Both analog and digital versions are available. The analog versions have a protective glass or crystal cover that is flipped open when time needs to be read and the clock-hands are constructed to not be susceptible to movement at the mere touch of the finger that a blind person uses to observe their positions. In the other form, the dots (like braille script) keep changing position as time changes. In this case, one must understand the Braille alphabet to make use of such watches. Electronic ''talking watches'', which speak the time at the touch of a button, are also popular among blind people. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Braille watch」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
