隨著科技進步，網際網路帶給人們便利的生活，讓資訊的流通達到零時差。許多網站提供線上新聞訊息，取代傳統印刷報紙，加上五光十色的廣告和內容豐富的影音片段，充實了視覺效果，吸引網路瀏覽者的目光。但是對於非以視覺來瀏覽的使用者來說，現在越來越多資訊僅以視覺方式呈現，往往會造成那些使用者有無法取得完整資訊的困擾，大大減低他們的使用效率與效果。
因此本研究模擬一適合視障者使用之線上新聞網站（FIONB），設計好用的無障礙介面以及簡易的操作步驟，讓使用者能在短期內迅速熟悉簡化過的介面與操作方式，讓使用者能輕鬆地瀏覽新聞，提升瀏覽過新聞內容的印象，減少搜索的時間，藉以提高使用者的使用績效。透過實驗結果確認FIONB能減少視障者瀏覽時的搜索時間，提升正確率，另外，使用者整體滿意度和學習績效亦為理想。
本研究結果證實，在做網站規劃時將特殊使用者的需求列入設計考量，能讓這些使用者獲得極大的幫助。期望未來發展能擴大範圍與對象，希冀有更多優秀人才共同投入這項研究發展，以期讓所有人都能得到網際網路帶來的便利，隨時透過網路瞭解最新資訊，跟上世界變化的腳步，減少因為自身障礙或環境限制所造成的阻礙，影響了學習的效果。

With the improving technology, Internet provides convenience to people for modern life. For the improvement of WWW, it is possible to transmit messages simultaneously between different parts in the world. Some web sites allow on-line news in place of traditionally printed newspaper. Usually, the web site contains multicolored advertisements and plentiful audio-visual contents to enrich the visual effects of the web page. These magnificent contents may make a deep impression on the users, but they may be useless for the blind.
Therefore, this research simulates an on-line news website for the blind. The friendly interface of on-line news for the blind (FIONB) is constructed with accessible interfaces and simplified operation process for the blind to browsing news easily and efficiently. Then, the effect of the FIONB was verified by an experiment. The experimental result, it is expected that the FIONB could promote the efficiency of browsing news and reduce searching time. Besides, the users were more satisfied with the simulator. We also anticipated that one would have better performance in learning.
