紅外觸摸(mo)屏的(de)工(gong)作原(yuan)理：

觸(chu)(chu)(chu)摸屏(ping)的(de)(de)(de)四(si)周(zhou)布滿紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)接(jie)收(shou)管(guan)和紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)發(fa)(fa)射(she)管(guan)，這些紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)管(guan)在(zai)觸(chu)(chu)(chu)摸屏(ping)表面呈(cheng)一(yi)一(yi)對(dui)(dui)應(ying)的(de)(de)(de)排列關系，形成(cheng)一(yi)張(zhang)由紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)線(xian)(xian)布成(cheng)的(de)(de)(de)光(guang)網，當(dang)有物體(手(shou)指、帶(dai)手(shou)套或任何(he)觸(chu)(chu)(chu)摸物體)進(jin)(jin)入紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)光(guang)網阻擋住某處的(de)(de)(de)紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)線(xian)(xian)發(fa)(fa)射(she)接(jie)收(shou)時，此(ci)點(dian)橫豎(shu)兩個方向(xiang)的(de)(de)(de)接(jie)收(shou)管(guan)收(shou)到的(de)(de)(de)紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)線(xian)(xian)的(de)(de)(de)強(qiang)弱(ruo)就會發(fa)(fa)生(sheng)變化，設(she)備通(tong)(tong)過了解紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)線(xian)(xian)的(de)(de)(de)接(jie)收(shou)情(qing)況的(de)(de)(de)變化就能知道何(he)處進(jin)(jin)行(xing)了觸(chu)(chu)(chu)摸。紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)觸(chu)(chu)(chu)摸屏(ping)通(tong)(tong)過硬(ying)件設(she)計和軟(ruan)件編程，可(ke)以對(dui)(dui)各點(dian)數(shu)據(ju)進(jin)(jin)行(xing)插值計算，可(ke)以達到32768 X 32768的(de)(de)(de)分辨率。在(zai)紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)觸(chu)(chu)(chu)摸屏(ping)工作時的(de)(de)(de)同一(yi)瞬(shun)間(jian)，只(zhi)有一(yi)對(dui)(dui)紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)對(dui)(dui)管(guan) (指物理位(wei)置相對(dui)(dui)應(ying)的(de)(de)(de)一(yi)只(zhi)發(fa)(fa)射(she)管(guan)和一(yi)只(zhi)接(jie)收(shou)管(guan))在(zai)進(jin)(jin)行(xing)數(shu)據(ju)工作，電(dian)路通(tong)(tong)過對(dui)(dui)紅(hong)(hong)(hong)(hong)外(wai)(wai)(wai)(wai)對(dui)(dui)管(guan)高頻率的(de)(de)(de)數(shu)據(ju)采(cai)集來(lai)達到迅速(su)反應(ying)的(de)(de)(de)效果，因此(ci)觸(chu)(chu)(chu)摸屏(ping)的(de)(de)(de)反應(ying)速(su)度非常快(kuai).

紅外線觸摸屏使用(yong)原理(li)：

在(zai)顯示(shi)器上(shang)(shang)加(jia)上(shang)(shang)光點(dian)距架框(kuang)（紅外(wai)觸(chu)(chu)摸(mo)框(kuang)），無需(xu)在(zai)屏(ping)(ping)(ping)幕(mu)表面加(jia)上(shang)(shang)涂層或(huo)接駁控制(zhi)器。光點(dian)距架框(kuang)的(de)四邊排(pai)列了(le)紅外(wai)線發射管及(ji)接收管，在(zai)屏(ping)(ping)(ping)幕(mu)表面形成(cheng)一個紅外(wai)線網。以手(shou)(shou)指(zhi)觸(chu)(chu)摸(mo)屏(ping)(ping)(ping)幕(mu)某一點(dian)，便(bian)會擋(dang)住經過(guo)該位置的(de)橫豎兩條(tiao)紅外(wai)線，計算機便(bian)可(ke)即(ji)時(shi)算出觸(chu)(chu)摸(mo)點(dian)位置。從(cong)而便(bian)可(ke)以代替了(le)傳統(tong)的(de)鼠(shu)標(biao)(biao)和鍵盤(pan)(pan)這樣的(de)外(wai)接設備，直接在(zai)顯示(shi)器上(shang)(shang)用手(shou)(shou)指(zhi)或(huo)者不透明(ming)名物體在(zai)顯示(shi)器上(shang)(shang)觸(chu)(chu)摸(mo)點(dian)擊任何(he)操(cao)作圖標(biao)(biao)，系統(tong)在(zai)接上(shang)(shang)觸(chu)(chu)摸(mo)設備時(shi)會自動(dong)(dong)出現(xian)觸(chu)(chu)摸(mo)軟(ruan)鍵盤(pan)(pan)，同樣可(ke)以在(zai)顯示(shi)桌面上(shang)(shang)使用軟(ruan)鍵盤(pan)(pan)操(cao)作，真(zhen)正意義上(shang)(shang)的(de)達到了(le)人機互動(dong)(dong)的(de)感念。觸(chu)(chu)摸(mo)屏(ping)(ping)(ping)的(de)出現(xian)也為不太習慣鼠(shu)標(biao)(biao)及(ji)鍵盤(pan)(pan)的(de)使用者帶(dai)來了(le)方(fang)便(bian)，可(ke)以直接在(zai)電腦桌面上(shang)(shang)手(shou)(shou)寫。隨著時(shi)代的(de)發展(zhan)，紅外(wai)觸(chu)(chu)摸(mo)屏(ping)(ping)(ping)可(ke)以實(shi)現(xian)多(duo)點(dian)操(cao)作及(ji)支持(chi)多(duo)人操(cao)作，這是傳統(tong)的(de)鼠(shu)標(biao)(biao)不能(neng)達到的(de)領域。
