手功能障礙者之掃瞄式電話撥接輔助系統

一般而言，電話的便利性已成為生活中不可或缺的一部份，然而，許多手功能障礙者無法隨心所欲地使用電話，享受電話所帶給我們方便。本篇論文的目的是為了設計一個簡單而且便宜的電話撥接介面，可使手功能障礙者能靠自己撥接電話，此介面主要包括四個主要的單元：輸入單元，微處理器控制單元，電話按鍵觸發電路單元，掃瞄式LED輸出顯示單元。我們要求十個人來為我們測試及評估此系統，結果平均撥一通8碼的電話號碼要花約107.1秒的時間。

In general, the conversation through telephones has become an important part of daily life. However, many physically disabled persons who have insufficient manual dexterity to operate a telephone keypad can not benefit from use of such a telephone communication system. The object of the work presented in the article is to design a simple and inexpensive telephone dialing aid, which allows disabled persons to dial telephones themselves. The dialing aid consists of four main blocks: an input unit, a microprocessor control unit, a keypad triggering circuit unit, and an LED output display unit. Ten persons were asked to evaluate a prototype of the dialing aid. On average, it took 107.1 seconds to make a 8-digit phone call.
