盛行率及發生率
• 視障人口增加
• 全球每五秒鐘就有一個人失去視力
• 根據世界盲人聯盟World Blind Union (WBU)統計,目前全球60
億人口中約有2.85億的視障者
• 台灣從1998年的32萬人,到2008年增加為55,569人,截至2011
年止,全台視障人口共56,091人(2011年內政部統計年報)
• 先天:遺傳、早產兒
• 後天:慢性病

視障的定義
• 種類
• 全盲
• 半盲(弱視)
• 視覺機能並未完全喪失,視力者0.1~ 0.2
左右之弱視者,均具有較少的障礙與較佳
的便利性
5
領有殘障手冊標準的定義
等級 障礙程度
重度 1.兩眼視力優眼在 0.01(不 含)以下者。
身心障礙之核定 標準,視力以矯正 視力為準,經治療 而無法恢復者
中度 1.兩眼視力優眼在 0.1(不含)以下者。
2.優眼自動視野計中心 24 度程式檢查,平均缺損大 於40 DB(不含)者。
3.單眼全盲(無光覺)而另眼 視力 0.2 以下(不含)者。
輕度 1.兩眼視力優眼在 0.1(含) 至 0.2 者(含)者。
2.兩眼視野各為 20 度以內 者。
3.優眼自動視野計中心 24 度程式檢查,平均缺損大 於 25 DB(不含)者。
4.單眼全盲(無光覺)而另眼 視力在 0.2(含)至 0.4(含) 者。

視覺障礙的原因
• 視網膜色素變性(俗名夜盲症)
• 黃斑部病變先天性白內障
• 青光眼
• 早產兒(氧氣過量致使網膜微血管增生)
• 高度近視引發視網膜剝離
• 腦瘤
• 腦膜炎
• 糖尿病性眼睛病變
• 意外(外力撞擊、車禍穿刺傷、化學性灼傷)

視覺障礙者在行動上面臨之困難
• Mobility-Related Accidents Experienced by People with Visual Impairment
• 探討視障者在使用導盲犬比使用白手杖 (white cane) 發生頭部意外的頻率
• 輔具的類型可能影響視障者外出的頻率
相關研究 I
9(Research and Practice in Visual Impairment and Blindness, 2011, Volume 4, Number 2)
許多的研究學者陸續開發出一些IT-based輔具,應用在行動安全方
面,以協助改善視覺障礙者的生活品質。
• The Guide Cane — Applying Mobile Robot Technologies to Assist the Visually Impaired
• 利用智慧型導引手杖協助使用者在室內避開障礙物
• 設計者卻無法協助使用者偵測平台上的掉落物 且不適用在戶外

體感輔具 幫視障者看路
聯合晚報 2013/5/10
定向行動導盲儀
資料來源 : 高雄市輔具資源中心
(一)它是利用聲納原理(回聲定位)將一反射波回彈辨識,再透過超
音波音頻不同的方式以達到聲音轉換為影像(Seeing with Sound)之
目的,可以讓視障朋友對周遭環境的辨識能力增強,彌補手杖在
定向行動,視障朋友身體上半部保護不足的缺失。透過聲音轉換
為影像的功能,盲人可以輕易辨識幾何形狀的物體、人物、 車輛
及道路....等不同狀況。
研究動機與目的
• 研究動機
• 許多為視覺障礙者所設計的行動輔具,未能實際應用在
真實生活上。
• 工程人員設計的IT-based輔助工具沒有考慮到視障者需求。
• 目的
• 發展一套設計準則提供IT設計人員參考,以設計出符合
視障者需求的輔具。
13
材料與方法
• 材料
•花蓮縣盲人福利協進會之個案
•年齡(20歲至45歲)與性別
•是否因其他疾病造成行動不便
•排除精神疾病、慢性病(退化性關節炎)
•排除先天失明
• 方法
•系統化文獻回顧
•資料分析
•問卷設計
•統計分析
