Vi presenterer en trinnvis veiledning for bygging og bruk av en eksperimentelle oppsett som tillater samtidig sporing av både øyne og dichoptic presentasjon av visuelle stimuli. I mange situasjoner der dichoptic stimulering brukes er kritiske problemet forhindrer effektiv øye sporing at speilene for dichoptic presentasjon blokkere synet av video-basert øye bane. Dette løses her ved hjelp av infrarød-gjennomsiktig speil og en infrarød-følsom øye sporing. Dette oppsettet kan forskere 3D vision, interocular undertr...

Under normale visningsforhold får hver av våre øyne en litt annen visuell inngang. Dette input behandles deretter for å produsere en sammenhengende, tredimensjonal fremstilling av verden. Dichoptic presentasjon, praktisering av uavhengig styre inndataene presentert for hver av de to øynene, dermed gjør forskerne studere hvordan mennesker rekonstruere en tredimensjonal fremstilling to todimensjonal retinal bilder2 ,3,4. I tillegg hvis de to øyne bilder er for ulik denne interocular kombinasjonen mislykkes og observatører i stedet rapportere oppfatning av bare ett av bildene samtidig mens andre forblir undertrykt, i fenomener som kikkert rivalisering5 og kontinuerlig flash undertrykkelse6. Forskere i slike interocular undertrykkelse, også bruke dichoptic presentasjon, i dette tilfellet å undersøke spørsmål knyttet til emner som neural locus bevissthet7, Perseptuell utvalg8,9og ubevisste behandler10.
Blikk og elev dynamics registreres for flere formål i menneskelig atferd og oppfatning. Blikk retning kan informere om, for eksempel oppmerksomhet tildeling11,10,13 og beslutning å14, mens elev størrelse kan åpenbare aspekter av visuell prosessering15, 16, oppgave engasjement17eller væske intelligens18.
Kombinere øye sporing med dichoptic presentasjon er nyttig i forskning i, for eksempel tre-dimensjonale (3D) oppfatning19,20,21,22 eller okulær svar på visuelle Angi under interocular undertrykkelse23,24,25. For eksempel er øyebevegelser funnet for å avsløre bevisstløs processing uten subjektive oppfatningen under kontinuerlig flash undertrykkelse23. Klinisk visuelle forskere kan bruke muligheten til å spore begge øynene under dichoptic presentasjon å undersøke øyet sykdommer som påvirker de to øynene asymmetrisk, for eksempel overvåke monocular og kikkerter visuelle forstyrrelser forekommer i amblyopi26 og maculopathy27.
Vi nylig beskrevet oppsett1 som gir kombinasjonen av høy kvalitet video-basert øye sporing og dichoptic stimulering med liten begrensning på størrelse eller farge på stimuli, og vi vurdert ytelsen. Nedenfor vil vi oppsummere bygging og bruk av dette oppsettet.

how to build a dichoptic presentation system that includes an eye tracker

Presentasjon av ulike stimuli til de to øynene, dichoptic presentasjon, er avgjørende for studier som involverer 3D visjon og interocular undertrykkelse. Det er en voksende litteratur på den unike eksperimentelle verdien av pupillary og oculomotor tiltak, spesielt for forskning på interocular undertrykkelse. Selv om å få øye-sporing tiltak ville dermed nytte studier bruker dichoptic presentasjon, maskinvaren avgjørende for dichoptic presentasjon (f.eks speil) ofte forstyrrer høykvalitets øye sporing, særlig når benytter en video-basert øye tracker. Vi har nylig beskrevet en eksperimentelle oppsett som kombinerer en standard dichoptic presentasjonssystem med en infrarød øye sporing ved hjelp av infrarød-gjennomsiktig speil1. Er kompatibel med standard-skjermer og øye bane, enkel å implementere og rimelig (på US$ 1,000). Forhold til eksisterende metoder den har fordelene ikke krever spesialutstyr og poserer noen begrensninger på natur og kvaliteten på visuelle stimulans. Her gir vi en visuell guide til bygging og bruk av våre oppsett.

Etter kalibreringen beskrevet i protokollen, utført vi en kalibrering-valideringsprosedyren uten problemer med speil på plass. Effektiviteten av metoden er tydelig illustrert av figur 5, som viser kameraets bilde (med en forskning slutten øye sporing system) med speilet i stedet. De to settene med parallelle linjer langs deltakernes nese og linjene over øyenbrynene er kantene av speil, men likevel ansiktet er så klart i rammen som utenfor. Dette understr...

How to Build a Dichoptic Presentation System That Includes an Eye Tracker

Vi nylig foreslått en metode som tillater dichoptic visuelle stimulans presentasjon og kikkerter øye sporing samtidig1. Nøkkelen er kombinasjonen av en infrarød øye sporing og tilsvarende infrarød-gjennomsiktig speil. Dette manuskriptet gir en grundig protokollen for innledende oppsett og daglige driften.
