【正文】 電腦等）、智能家居等各個領(lǐng)域得到廣泛應(yīng)用，這些產(chǎn)品的使用在改變?nèi)藗兩罘绞降耐瑫r也提高人們生活效率和生活質(zhì)量。利用嵌入式功耗低、可靠性與穩(wěn)定性好、體積小等特點(diǎn)，將嵌入式應(yīng)用到一些微小的智能終端中是嵌入式的未來發(fā)展方向，目前比較成功的案例如安卓手機(jī)和 ios 手機(jī)，其就是依照嵌入式開發(fā)的手機(jī)系統(tǒng)，已經(jīng)遍布世界各地。現(xiàn)在市面上雖然有很多種基于嵌入式開發(fā)的輸入法。 II THE DESIGN OF THE PINYIN INPUT METHOD BASED ON LINUX ABSTRACT Embedded technology from birth to today, especially for nearly 20 years of development, has made great been widely applied in many an excellent embedded products, has a good user interface is country is a populous country with a huge spending power, so a GUI systems that support the Chinese input method there is a pressing need for domestic users, also to the development of embedded itself also has the great significance. This paper first summarizes the Embedded Linux system, and its development history and status quo, and then introduces the design input method the implementation of the environment (Qt/Embedded) and related technologies, the development principle, etc., and on the basis of the pletion of the GUI design and the realization of the input developed an excellent interface (soft keyboard) of Chinese pinyin input method. KEY WORDS Pinyin input method, embedded Linux, Qt/E, the GUI1 1 緒論 目前， 3G 已經(jīng)發(fā)展到鼎盛時期， 4G 也正在加速建設(shè)中，這些技術(shù)的快速前進(jìn)，讓我們隨時隨地連接互聯(lián)網(wǎng)成為了可能，這也使得嵌入式系統(tǒng)在性能與應(yīng)用領(lǐng)域上有了很大的進(jìn)步，眾多智能終端產(chǎn)品中廣泛采用液晶顯示屏 和 軟 鍵盤 組成的 人機(jī)交互界面。 我國是一個人口大國，有著巨大的消費(fèi)能力， 因此一款支持中文輸入法的 GUI 系統(tǒng)對于國內(nèi) 用戶來說有著迫切的需求， 也 對嵌入式本身的發(fā)展也具有巨大的意義。鄭州輕工業(yè)學(xué)院 本科畢業(yè)設(shè)計(jì)（論文） 題 目 基于 Linux 的拼音輸入法設(shè)計(jì) 學(xué)生姓名 專業(yè)班級 信息工程 1101 學(xué) 號 5 院 （系） 計(jì)算機(jī)與通信工程學(xué)院 指導(dǎo)教師 完成時間 20xx 年 06 月 06 日 基于 Linux 的拼音輸入法設(shè)計(jì) 目 錄 摘 要 ....................................................................................................................................
