Uwemi wa infrable touchscreen ngwakuti ungakhwaskika na chala, peni, panji chinthu chilichose icho chikukanizga ungweru. Uheni wa skrini ya infrared touch ngwawemi yayi kugwiliskira nchito pa cilongolero cakuzungulira, ici nchifukwa cakuti mulimo wa infrared grating matrix ukukhumbikwa makora kuti ndege yimoza, ntheura kukhwaskana nadi kwa mtunda wa ndege yakukhotakhota kulije nyengo yikuru, comenecomene pa ngodya, kweni suzgo ili pa cilongolero ca screen la flat lilipo yayi, nga ni cilongolero ca kristalo wa maji. Tingakamba kuti kugwiriskiya nchitu chilongolu cha pa panelo cha flat, skrini ya infrared yili na vitumbiko vinandi.
Nthowa yakumanyira infrared yikugwiriskira ncito chubu cha mafunde cha mafunde ghamoza, chubu cha infrared receiver (icho chikuchemeka kuti infrared chubu) chingaŵa nthowa yipusu yakumanyira infrared:
Para pali vinthu ivyo vikukanizga kulumikizgana pakati pa infrared na chubu, chimanyikwiro cha kupokera chikukhira chomene, ntheura infrared yingamanya kuti chinthu chikutchinga, mu dongosolo la anti {- dongosolo la ft, dongosolo la kumanyikwa kwakujiyimira paŵekha, ma counter na vinyake ivyo vikugwiriskirika nchito chomene. Infrared usange chiziŵizgo cha-} range, kuyana na msinkhu wa kuchepeskeka wa chimanyikwiro chakupokelereka kungamanyaso msinkhu wa kutchinga, iyi ndiyo so -}}ed mode ya analog, nthowa ya analog mu receiver mwakugwiliskira ntchito mzere wakupokelera, kweniso pa vithuzithuzi vyakupambana; Kuti ŵaleke kunjilirapo, kumanya kwa infrared kungagwiliskiraso ntchito pulse mode, ndiko kuti, infrared chubu chikufumiska chimanyikwiro cha pafupipafupi, ndipo wakupokelera waka chifukwa cha kumanyikwa kwa pafupipafupi uku, mtundu wa pulse anti- jamming luso nkhwakukhora chomene. Pulse mode usange chimanyikwiro chasinthika mu nyengo yakugwira ntchito, kweniso pa kuyowoyeskana kwa digito, uko nkhwakumanyikwa kwakumanyikwa kwa infrared, vyakugwiriskira ntchito pa nyumba, kulaŵilira kutali, kulumikizgana kwa kompyuta, kuyowoyeskana kwa infrared kwa pa kompyuta, ndiposo nanga nkhudumbiskana kwa fiber yakuwoneka mwaluŵiro, vyose chifukwa cha ichi. Kudumbiskana kwa infrared kulije nkhongono pa thupi la munthu, ndipo mtunda wakukhazikiska ni ufupi ndipo palije kufipiskika kwa malo, lero nkhwakukhozga chomene - gaze. Chaputala ichi nkhukhwaska pa sikirini, mungazunguliranga yayi chinyake, kweni kufuma ku mbumba iyi kuti muŵe ŵakukhora, mungawonaso munthazi wakutowa wa skrini ya infrared.
