摘要

隨著資訊的發達，搜尋引擎已成為網路上獲取資訊重要的媒介。然而網站的設計常未考慮網頁的親和力，使得視障者在瀏覽網頁、資訊獲取上常常遭遇許多的困難。本研究以客戶端的JavaScript為工具，改善搜尋引擎的既有介面，使其更適合盲人們使用螢幕閱讀軟體或點字閱讀，並且提供不同搜尋引擎間相同的介面及功能，使得使用者可以有效率的在不同的搜尋引擎間獲取資訊，並且展示了客戶端JavaScript可以有效的改良網頁介面。實驗以五名視障者為對象，實驗的結果顯示SCSJ可以有效的提高視障者獲取資訊的效率。未來希望可以應用於其他常用的網站，使得網路上所有人可以不因為先天的障礙而阻礙了自由獲取資訊的能力。

With the development of information technology, search engines have become a necessary media in searching for information on the internet. However, the design of websites usually did not take web accessibility into consideration and visually impaired users encountered difficulties in retrieving required information.

The current study used client-side JavaScript to improve the interfaces of the search engines. The objectives are making interfaces more suitable for visually impaired users either with screen reader or Braille and providing the same interface and functions for different search engines. The above-mentioned achievements can make the search tasks more efficient for all users and also demonstrate that client-side JavaScript can better website interfaces.

The study had 5 blind participants to try out Specialized Client-Side JavaScript (SCSJ). The results showed that SCSJ successfully enhanced the efficiency in acquiring information for the blind. It is hoped SCSJ can be applied to other websites and make information easy access to everyone.
