Projection ya clavier n'uburyo bw'igikoresho cyinjiza mudasobwa aho ishusho ya clavier isanzwe iteganijwe hejuru, iyo umukoresha akoresha ku buso butwikiriwe n'ishusho y'urufunguzo, igikoresho gikoresha urufunguzo cyandika. Bamwe bahuza ibikoresho bya Bluetooth, harimo byinshi bya terefone igezweho, tablet, hamwe na mini-PC hamwe na sisitemu y'imikorere ya Android, iOS cyangwa na Windows.
Mwandikisho ya y'insakazamashusho yahimbwe kandi ihabwa patenti naba injeniyeri ba IBM mu mwaka 1992. Ihitamo neza inasesengura imigendekere y'intoki z'abantu, ikanabisobanura nk'ibikorwa ku gikoresho cy'injiza kidahari nk'ubuso bufite urufunguzo rusize irangi cyangwa rugaragazwa. Muri ubwo buryo, irashobora kwigana ubwoko butagira imipaka bw'ibikoresho byinjiza intoki (nk'imbeba, clavier, n'ibindi bikoresho). Ibikoresho byinjiza bishobora gusimburwa nibikoresho nkibi, birashoboka ko byashyirwa mu bikorwa bya porogaramu yihariye no kuri physiologiya y'umukoresha, bikomeza umuvuduko, ubworoherane, hamwe no kudasobanuka kw'amakuru winjiza.
Mu mwaka 2002, isosiyete yatangije Canesta yakoze clavier ya projection ikoresheje "tekinoroji ya elegitoroniki." Isosiyete yaje guha ikoranabuhanga Celluon yo muri Koreya.
Ni sisitemu yatanzwe bitwa P-ISM ihuza ikoranabuhanga na progaramu ntoya ya videwo yo gutangiza cyangwa gukora mudasobwa igendanwa ingana n'ikaramu ya fountain . [1]
Laser cyangwa beamer imishinga igaragara ya clavier igaragara k'urwego rwo hejuru. Nibikoresho bigezweho. Rukuruzi cyangwa kamera m'umushinga ufata urutoki . Porogaramu ihindura imirongo kugira ngo imenye ibikorwa cyangwa inyuguti.
Ibikoresho bimwe byerekana isegonda (itagaragara ya infragre ) hejuru ya clavier isanzwe. Urutoki rw'umukoresha rukora k'urufunguzo kuri mwandikisho isanzwe. Ibi bimena cyangwa rukananiza urumuri rwa infrared kandi bikagaragaza urumuri rugaruka k'umushinga cyangwa kugikorwa nyirizina. Ikigaragaza urwo rumuri kinyura muyungurura ya infragre kuri kamera. Kamera ifotora inguni y'umucyo winjira. Chip ya sensor igena aho urumuri rwa infragre rwacitse. Porogaramu igena ibikorwa cyangwa imiterere igomba gukorwa.
Igishushanyo kiboneka mu ntambwe enye zingenzi kandi binyuze m'uburyo butatu, module ya projection, sensor module na illumination module. Ibikoresho by'ingenzi n'ubuhanga bukoreshwa m'ugushushanya ishusho n'ibintu bitandukanya, diode itukura ya laser, chip ya sensor ya CMOS hamwe na diode ya infragre (IR).
Inyandiko rugero yakozwe na progaramu idasanzwe kandi ikora neza cyane ya projection hamwe na laser itukura ya diode hejuru y'imbere. [2] Inyandiko rugero ntabwo ariko igira uruhare mubikorwa byo gutahura.
Usibye gukoreshwa gusa kugira ngo wandike, sisitemu zimwe na zimwe za lazeri zirashobora gukora nk'imbeba isanzwe ikoreshwa na mudasobwa cyangwa ndetse nka piyano isanzwe, nka iKeybo iterwa inkunga n'abantu. [3]
