輔助視障者學習中文點字之系統

在台灣的視障族群中，可依照失明年齡區分為從小失明(先天盲)及中途失明(後天盲)兩種。「中途失明者」原本擁有正常的視力，其後因疾病或意外傷害而導致失明；這些視障者因從未接受過特殊教育，因此需要另外學習點字來進行以手代眼的點寫與摸讀。本研究為視障者設計一套學習中文點字的輔具，以縮短視障者學習點字點寫技能時所需的訓練時間；此系統的硬體設施包含點字學習手套、平版電腦等兩個部分。首先視障者需穿戴本研究所開發的點字學習手套，接著平版電腦根據點字點寫的訓練內容，控制手套上的震動馬達，以產生所對應的點字輸入指法。透過反覆的震動來加強視障者點寫時的肌肉記憶，以期縮短視障者學習點寫技能所需的時間。

In Taiwan, part of visual impairment are cause by disease or injury. Most of them do not study in a special-education school when they are young. Therefore, they need to study Braille reading and typing after blind. To help these visual impairment in Taiwan, we designs a learning aid to shorten the time for visual impairment to study Braille typing. The aid composes with a learning pair gloves and a teaching app operating on a tablet PC. For a single glove, three vibrating motors are set at finger and controlled by a micro-controller. To study Braille typing, the visual impairment first puts on the gloves; then the developed teaching app output the voice message and controls the vibrating states of motors corresponding to teaching materials. According the field trials, we find the proposed aid can help visual impairment to study Braille typing and shorten the time of learning.
