摘要

輔具是經過設計或改造的工具設備或產品。用來增進、維持或是改善身心障礙功能。而現在輔具的使用族群已經不再是僅侷限於身心障礙者，包括老年人、慢性病患者甚至於一般人都有機會使用到。就一般人而言，使用輔具的目的不外乎要提升工作效率、降低工作壓力、及減低生理疲勞。而就身心障礙者及老年人而言則是要增加生活的獨立性機動性、減輕照護者的負擔、減少意外災害的發生、降低醫療支出的花費、提高照顧者與老年人長者同住的意願、提高生活品質，從心理層面來看，輔具的使用能增進使用者對於環境的控制能力、增加與周遭環境之間更多的互動，進而提升使用者的自尊心及自我生活的概念，同時減低照護者的心理負擔。
輔具的分類至今尚無國內外共同統一的規範與標準，一般而言最常見的分類由下圖所示。生活中的輔具主要可分為生活輔具、行動輔具、視覺輔具及醫療復健輔具等四大項，而此輔具分類中不只是針對銀髮族，還有其他在生活適應上會產生其他障礙的族群。

而在這些分類當中，其中又以行動輔具的規模最為龐大。行動輔具的定義即是一種活動輔助的裝置，用來輔助四肢力量退化的人行走或是改善矯正在行動方面有損傷的人們走路。生活中有許多不同的行動輔具，其分類如上圖所示。常見的行動輔具行動輔具有輪椅、手杖、四輪電動機車，其中生活裡最為普遍的莫過於是傳統的助行器與輪式的助行器了。

Abstract

Aids device is the product or the tool facilities that have been designed or modified to enhance, maintain and even improve the disability function. The group of Aids user is not only limit in disability man but elderly and chronic disease people, even the normal people would use it. For the normal people, the aim to use Aids device is to increase the work efficiency, lower the work pressure and cut down the fatigue on body. For the disability and elderly, aids can not only increase flexibility and independence of his own but decrease the burden and accident.
The classification of aids haven’t been ruled from now on. The aids in life can be categorized as life aids, mobile aids, visual aids, and medicare aids.
The mobile aids is the most huge extent of them. The definition of mobile aids is that can be a supplementary and assistance for those who lost their body force. So the research would develop a device that can assist disability people to live by themselves in the urban.
