摘要

身心障礙者無線家庭自動化系統之研製

黃志銘 * 羅錦興 **

國立成功大學電機工程學系

身心障礙人士往往由於先天或後天的限制而在日常生活上有著諸多的不便與障礙。為了改善其生活品質，家庭自動化系統之輔助可視為最直接有效的方式。然而殘障人士的個別情況不一，使用需求亦常常因人而異，故人性化的控制介面、簡易的操作模式以及可調整的功能規劃是設計上的重要考量。

本論文中，作者提出一整合性的系統，此系統以無線傳輸建構使用者端與家電端之連結，讓使用者可以很方便的來進行家電控制；另外輔以電力線載波傳輸來擴展電器應用的範圍，以實現超越空間限制之全家庭通訊架構。為能適用於不同的個案狀況，本系統提供了多種類型的使用者介面，身心障礙者透過簡易的操作即可控制家中電器，如此更貼近個人化服務之設計。

ABSTRACT

A Wireless Home Automation System for the Disabled

Chih-Ming Huang * Ching-Hsing Luo**

Department of Electrical Engineering
National Cheng Kung University

Persons with disabilities usually feel awkward and frustrated in their daily lives due to congenital or acquired diseases. To improve their quality of life, home automation systems are effectual auxiliaries. However, their disabilities are dissimilar and so are their requirements. Hence, user-friendly control interfaces, simple mode of operations and flexible programming are significant considerations in system design.

In this thesis the author brought up an integrated system that is based on wireless connection between users and home appliances and CEBus power-line transmission for implementation on whole house communication. The system provides various types of user interface in order to suit different cases. Thus this custom-built system indeed serves the disabled well.
