摘 要
觸摸屏的應(yīng)用隨著信息社會的發(fā)展越來越普遍，目前觸摸屏產(chǎn)品在中國已開始形成了產(chǎn)業(yè)，本文專題介紹有關(guān)觸摸屏的相關(guān)基礎(chǔ)技術(shù)知識。
隨著多媒體信息查詢的與日俱增，人們越來越多地談到觸摸屏，因?yàn)橛|摸屏作為一種最新的電腦輸入設(shè)備，它是目前最簡單、方便、自然的而且又適用于中國多媒體信息查詢國情的輸入設(shè)備，觸摸屏具有堅(jiān)固耐用、反應(yīng)速度快、節(jié)省空間、易于交流等許多優(yōu)點(diǎn)。利用這種技術(shù)，我們用戶只要用手指輕輕地指碰計算機(jī)顯示屏上的圖符或文字就能實(shí)現(xiàn)對主機(jī)操作，從而使人機(jī)交互更為直截了當(dāng)，這種技術(shù)極大方便了那些不懂電腦操作的用戶。這種人機(jī)交互方式。它賦予了多媒體以嶄新的面貌，是極富吸引力的全新多媒體交互設(shè)備。
隨著城市向信息化方向發(fā)展和電腦網(wǎng)絡(luò)在日常生活中的滲透，信息查詢都會以觸摸屏——顯示內(nèi)容可觸摸的形式出現(xiàn)。所以對于觸摸屏軟件的設(shè)計是非常具有實(shí)際意義和發(fā)展前景的一項(xiàng)課題。
本論文研究基于ucos2的觸摸屏軟件的設(shè)計，首先了解觸摸屏的現(xiàn)狀和發(fā)展前景，研究觸摸屏的特點(diǎn)為觸摸屏的軟件設(shè)計打下基礎(chǔ)。其次進(jìn)行對ucos2平臺的學(xué)習(xí)，了解他的特點(diǎn)、性能、技術(shù)指標(biāo)、支持軟件。再次，全面學(xué)習(xí)嵌入式平臺的特點(diǎn)、性能支持以及注意事項(xiàng)。最后利用VC模擬在ucos2平臺下的軟件界面設(shè)計。

ABSTRACT
 
    Application of touch screen the development of information society more and more common, the current touch-screen products in China has started to form the industry, this presentation based on the touch screen of the relevant technical knowledge.
With the ever-increasing multimedia information search, more and more people spoke touchscreen, as the latest touch-screen as a computer input device, which is the most simple, convenient, natural, and they apply to China's national conditions of multimedia information query inputequipment, touch screen with a durable, fast response, space-saving, easy to communicate and many other advantages.With this technology, our users pointed a finger gently touching icons on a computer screen or text on the host OS can be achieved, thus making the machine interaction more straightforward, this technique greatly facilitate those who do not knowcomputer users.The human-computer interaction.It gives the media a new look, a very attractive new multimedia interactive devices.
    With the city to develop in the direction of information and computer network penetration in their daily lives, information inquiry will be the touch screen - display the form of touch.Therefore, the design of software for the touch screen is of practical significance and prospects for development of a subject.
    In this study, the touch-screen based ucos2 software design, the touch screen to first understand the current situation and development prospects of the touch screen features of the software for the touch-screen basis.Secondly, the study carried out on ucos2 platform, and understand the characteristics, performance, technical indicators, support software.Again, a comprehensive study of the characteristics of embedded platforms, performance support, and considerations.Finally, VC simulation ucos2 platform software interface design.

Keywords: touch screen, ucos2,vc6.0,software design.
