電容式觸摸感應(yīng)從異國(guó)情調(diào)到日常

　　本文介紹了觸摸傳感和開(kāi)關(guān)技術(shù)的發(fā)展。電容傳感技術(shù)。產(chǎn)品被包括獨(dú)立的電容傳感控制器IC和微控制器（MCU），包括觸摸感應(yīng)作為外設(shè)功能。

　　電容式觸摸感知經(jīng)歷了爆炸式的增長(zhǎng)，成為幾類消費(fèi)產(chǎn)品的默認(rèn)人機(jī)界面。平板電腦、智能手機(jī)、便攜式媒體播放器和GPS系統(tǒng)的用戶現(xiàn)在都希望有一個(gè)先進(jìn)而靈敏的觸摸界面。反過(guò)來(lái)，這也改變了用戶對(duì)智能設(shè)備和家用電器市場(chǎng)的期望；現(xiàn)在消費(fèi)者開(kāi)始使用TAP、拖動(dòng)、刷卡和捏的語(yǔ)言進(jìn)行預(yù)編程。高端產(chǎn)品不提供用戶交互模式的風(fēng)險(xiǎn)被“酷”。

　　2012推出的Windows 8只增強(qiáng)了觸摸界面的擴(kuò)散，促使平板電腦和個(gè)人電腦制造商在便攜式計(jì)算領(lǐng)域嘗試新的格式。那些將觸摸現(xiàn)象視為從智能手機(jī)/數(shù)字助理空間演變而來(lái)的人認(rèn)為微軟的Surface產(chǎn)品是一種相對(duì)大的屏幕格式；然而其他PC制造商正在用更大的平板式產(chǎn)品測(cè)試市場(chǎng)。從它唯一的接口——智能手機(jī)——進(jìn)入鍵盤不可或缺的空間的角度來(lái)看，很可能會(huì)看到消費(fèi)者與技術(shù)交互方式的進(jìn)一步發(fā)展。

　　In fact， the touch paradigm appeared in the PC market early in its development. Hewlett-Packard offered a product in the 1980s that used a touch interface， although that used infrared sensing to detect the presence and location of a finger. The first mentions of touch interfaces associated with screens date back decades earlier， with historical accounts quoting an early capacitive-touch system conceived as a means of interfacing with a radar system.

　　Prior to the current upswing in deployment of touch technology， most consumers‘ experience of the technology was limited to a small number of applications， largely in areas such as vending kiosks/ATMs. Those mostly used resistive touch technology， or occasionally infrared （where an X/Y matrix of IR beams is placed immediately above the screen） and were invariably single-point detection systems.
