基于光學(xué)感應(yīng)的大尺寸多點(diǎn)觸摸控制技術(shù)
結(jié)語
本文引用地址:http://www.ex-cimer.com/article/97909.htm本文介紹了多點(diǎn)觸摸控制系統(tǒng)的基本原理,展示并分析了常見的基于光學(xué)感應(yīng)的多點(diǎn)觸摸實(shí)現(xiàn)方案的優(yōu)缺點(diǎn),深入研究了基于Touchlib的多點(diǎn)應(yīng)用系統(tǒng)框架,及其與上層應(yīng)用程序之間的數(shù)據(jù)傳送協(xié)議和方法,并給出了一種基于70寸高清背投電視的大尺寸光學(xué)感應(yīng)多點(diǎn)觸控應(yīng)用系統(tǒng)解決方案。當(dāng)然,本文的初步結(jié)果是基于主動紅外觸摸筆的形式,人與機(jī)器之間還是借助了外部設(shè)備,并不是直接的肢體觸摸,而且還不能支持手勢識別。
可以預(yù)見,多點(diǎn)觸摸人機(jī)界面及其相關(guān)技術(shù)有著非常廣泛的應(yīng)用前景,特別是大尺寸、低成本的多點(diǎn)觸摸控制系統(tǒng)是值得廣大業(yè)界同仁深入研究的。
