Kev loj hlob

Cov kev loj hlob ntawm multipoint touchscreens thawm lub mus txog qhovtwg los ntawm ntau tshaj ib tug ntiv tes rau ntawm qhov screen; yog li, ua hauj lwm uas yuav tsum tau ntau tshaj li ib tug ntiv tes yog ua tau. Cov pab kiag li lawm kuj cia ntau cov neeg mus nrog cov touchscreen ib txhij.

Nrog rau cov loj hlob siv touchscreens, lub marginal nqi ntawm touchscreen technology yog routinely absorbed rau hauv cov khoom uas teeb rau thiab yog ze li ntawm tshem tawm. Touchscreens tam sim no muaj pov thawj kev ntseeg. Yog li, touchscreen qhia muaj nyob niaj hnub no nyob rau hauv dav hlau, tsheb, gaming consoles, tshuab tswj systems, khoom siv, thiab handheld zaub pab kiag li lawm xws li cov Nintendo DS thiab multi-kov enabled cellphones; lub touchscreen ua lag luam rau mobile pab kiag li lawm twb npaj mus ua US $ 5 billion los ntawm 2009.

Cov muaj peev xwm kom meej taw tes rau qhov kev tshuaj ntsuam nws tus kheej yog tseem uas nrog lub qho graphics ntsiav tshuaj / screen hybrids. PVDF plays ib tug luag hauj lwm loj nyob rau hauv no innovation vim nws cov high piezoelectric zog.

TapSense, tshaj tawm nyob rau hauv Lub kaum hli ntuj 2011, tso cai rau touchscreens kom paub qhov txawv li cas ib feem ntawm lub tes siv rau cov tswv yim, xws li cov muab ntiv tes, khauj tsiav thiab rau tes. Qhov no yuav tsum tau siv nyob rau hauv ib tug ntau yam ntawm txoj kev, piv txwv li, rau daim ntawv thiab muab tshuaj txhuam, capitalize cov tsiaj ntawv, mus qhib txawv duab hom, thiab zoo sib xws.


Ergonomics thiab pab

touchscreen raug

Cov neeg siv yuav tsum tau los yog xaiv lub hom phaj rau touchscreens, thiab tsis txhob yuam xaiv ntawm ib sab lub hom phaj, kom zoo siv ib tug touchscreen tswv yim ntaus ntawv. Tus tsim ntawm touchscreen interfaces yuav tsum muaj kev cuam tshuam ob leeg kev peevxwm ntawm qhov system, ergonomics, kev txawj ntse psychology thiab tib neeg tej hlab ntshav.

Cov txheej txheem rau touchscreen designs twb xub tsim nyob rau hauv lub Kwvyees li xyoo 1990, raws li nyob rau hauv thaum ntxov kev tshawb fawb thiab siv ntawm cov laus systems, yog li xav tias kev siv ntawm kev kawm tsoov technology xws li infrared sob. Cov touchscreens no mas nyob rau ntawm qhov luaj li cas ntawm tus neeg siv lub ntiv tes, yog li lawv cov lus qhia yog tsawg yam rau lub ib thooj ntawm niaj hnub pab kiag li lawm, siv capacitive los yog resistive touch technology. Los ntawm nruab nrab-2000s onward, makers ntawm kev khiav hauj lwm systems rau smartphones tau cai qauv, tab sis cov no sib txawv ntawm manufacturers, thiab tso cai rau tseem ceeb variation nyob rau hauv loj raws li nyob rau hauv technology hloov, thiaj li yog unsuitable los ntawm ib tug tib neeg yam foundations.

Ntau npaum li cas ib qho tseem ceeb yog cov neeg tib neeg muaj nyob rau hauv xaiv lub hom phaj nrog lawv cov ntiv tes los yog ib tug cwj mem stylus. Cov neeg ntawm tus neeg siv xaiv mas nws txawv ntawm txoj hauj lwm ntawm qhov screen. Cov neeg siv yog tshaj plaws yog rau ntawm qhov chaw, tsawg li nyob rau sab laug thiab txoj hau, thiab ntau tsawg tseeb nyob rau sab saum toj thiab tshwj xeeb tshaj yog hauv qab npoo. Lub R95 raug mas nws txawv ntawm 7 hli nyob rau hauv qhov chaw, rau 12 hli nyob rau hauv lub qis cov ces kaum. Cov neeg siv yog subconsciously paub txog qhov no, thiab kuj muaj me ntsis qeeb qeeb, kev noj ntau lub sij hawm mus xaiv me me lub hom phaj, thiab tej thaum cov npoo thiab cov ces kaum.

Qhov no inaccuracy yog ib tug ntawm parallax, nrig txog kev pom acuity thiab cov kev ceev ntawm lub tswv yim voj ntawm lub qhov muag thiab cov ntiv tes. Cov precision ntawm tus tib neeg cov ntiv tes ib leeg yog npaum li cas, ntau npaum li cas siab tshaj no, yog li thaum pab technologies yog muab xws li on-screen magnifiers, cov neeg siv yuav tsiv mus nyob lawv cov ntiv tes (ib zaug nyob rau hauv kev sib cuag nrog lub screen) nrog precision li me me raws li 0.1 hli.


Tes hauj lwm, lej siv thiab switching

Cov neeg siv handheld thiab portable touchscreen pab kiag li lawm tuav lawv nyob rau hauv ib tug ntau yam ntawm txoj kev, thiab routinely hloov lawv txoj kev ntawm tuav thiab xaiv kom haum rau txoj hauj lwm thiab hom tswv yim. Muaj plaub theem pib hom ntawm handheld sis:

Tuav tsawg kawg yog nyob rau hauv ib feem nrog ob txhais tes, tapping nrog ib tug hluas ntiv tes xoo

Tuav nrog ib txhais tes, tapping nrog tus ntiv tes (los yog tsis tshua muaj, tus ntiv tes xoo) ntawm lwm tes

Tuav tus ntaus ntawv nyob rau hauv ib tes, thiab tapping nrog tus ntiv tes xoo los ntawm hais tias txhais tes

Tuav nrog ob txhais tes thiab tapping nrog ob thumbs

Siv cov nqi sib txawv nyias li. Thaum ob-ntiv tes xoo tapping yog ces yuav tsum tsis tshua muaj (1-3%) rau ntau general kev sib tshuam, nws yog siv rau 41% ntawm cov typing sis raug zoo.

Nyob rau hauv tas li ntawd, pab kiag li lawm yog feem ntau muab tso rau hauv txee (desks los yog lub rooj) thiab cov ntsiav tshuaj tshwj xeeb tshaj yog yog siv nyob rau hauv sawv. Tus neeg siv yuav taw tes, xaiv los yog piav tes piav taw nyob rau hauv cov neeg uas muaj lawv cov ntiv tes los yog ntiv tes xoo, thiab kuj txawv qhov siv.


Nrog haptics

Touchscreens yog feem ntau siv nrog haptic teb tshuab. Ib tug ntau cov piv txwv ntawm no technology yog lub Vibratory tswv yim muab thaum ib lub pob rau lub touchscreen yog tapped. Haptics yog siv los txhim kho cov neeg siv cov kev nrog touchscreens los ntawm kev muab simulated tactile tawm tswv yim, thiab muaj peev xwm yuav tsim los hnov mob tam sim ntawd, tej countering on-screen teb latency. Kev tshawb fawb los ntawm lub University of Glasgow Scotland [Brewster, Chohan, thiab Brown 2007 thiab ntau tsis ntev los Hogan] qha tau tias qauv neeg siv txo cov tswv yim uas tsis (20%), ua rau kom cov tswv yim ceev (20%), thiab txo lawv kev txawj ntse load (40%) thaum touchscreens ua ke nrog haptics los yog tactile tswv yim [vs. uas tsis yog-haptic touchscreens].


"Liab twm hawj caj npab"

Ncua kev siv cov gestural interfaces tsis muaj tus muaj peev xwm ntawm tus neeg siv mus so lawv caj npab yog raug xa mus rau raws li "liab twm hawj caj npab." Nws yuav ua tau nyob rau hauv qaug zog, thiab txawm repetitive kev nyuaj siab kev raug mob thaum routinely siv nyob rau hauv ib tug ua hauj lwm qhov chaw. Tej yam thaum ntxov cwj mem-raws li interfaces yuav tsum tau tus neeg tsav tsheb mus ua hauj lwm nyob rau hauv no txoj hauj lwm rau ntau ntau lub chaw ua hauj lwm hnub. Tas cov neeg siv yuav so lawv tes los yog caj npab rau lub tswv yim ntaus ntawv los yog ib tug ncej nyob ib ncig ntawm nws yog ib cov tshuaj rau qhov no nyob rau hauv ntau cov ntsiab lus. Qhov no tshwm sim feem ntau yog raug nplua raws li ib tug prima facie piv txwv ntawm dab tsis txhob ua nyob rau hauv ergonomics.

Unsupported touchscreens tseem haum ntau nyob rau hauv daim ntaub ntawv xws li ATMs thiab cov ntaub ntawv kiosks, tab sis yog tsis yog ib qho teeb meem raws li tus raug cov neeg siv xwb txhawb cov tub ntxhais rau nyuag thiab dav spaced sij hawm.


cov yiv tes

Touchscreens yuav raug kev txom nyem los ntawm qhov teeb meem ntawm cov yiv tes ntawm cov zaub. Qhov no yuav ua mitigated los ntawm kev siv cov ntaub ntawv nrog kho qhov muag coatings tsim los txo tus pom zoo los ntawm cov tuabneeg roj, los yog oleophobic coatings raws li feem ntau ntawm cov niaj hnub smartphones, uas thim lub sij nqi ntawm cov roj residue (uas muaj xws li dej cawv), los yog los ntawm txhim kho ib tug matte-finish anti-glare screen protector, uas tsim ib tug me ntsis roughened chaw uas tsis yooj yim khaws smudges.
