Vi præsenterer en trinvis guide for konstruktionen og brugen af en eksperimentel opsætning, der giver mulighed for samtidige inddeling af begge øjne og dichoptic præsentation af visuelle stimuli. I mange situationer hvor dichoptic stimulation er brugt, er det kritiske spørgsmål forhindrer effektiv eye tracking at spejle for dichoptic præsentation blokere synet af video-baseret øje trackers. Dette er løst her ved hjælp af infrarød-gennemsigtig spejle og en infrarød-nærtagende øje tracker. Denne opsætning g?...

Under normale visningsforhold modtager hver af vores øjne en lidt anderledes visuelle input. Dette input behandles derefter for at producere en sammenhængende, tre-dimensionelle repræsentation af verden. Dichoptic præsentation, praksis uafhængigt kontrollere input præsenteret for hver af de to øjne, således gør det muligt for forskere at studere, hvordan mennesker genopbygge en tre-dimensionelle repræsentation fra to to-dimensionelle retinal billeder2 ,3,4. Desuden, hvis de to øjne billeder er for forskellige, denne interocular kombination mislykkes, og observatører i stedet indberette opfattelse af kun én af billederne på en gang, mens den anden fortsat undertrykt, i fænomener som kikkert rivalisering5 og kontinuerlig flash undertrykkelse6. Forskere med sådanne interocular undertrykkelse, også bruge dichoptic præsentation, i dette tilfælde til at undersøge spørgsmål i forbindelse med emner som det neurale locus af bevidsthed7, perceptuelle udvalg8,9, og ubevidste behandling af10.
Blik og elev dynamics registreres til flere formål i forskning om menneskelig adfærd og opfattelse. Blik retning kan informere om, eksempelvis opmærksomhed tildeling11,10,13 og beslutning at gøre14, mens pupilstørrelse kan afsløre aspekter af visuel behandling15, 16, opgave engagement17eller flydende intelligens18.
Kombinere eyetracking med dichoptic præsentation er nyttige i forskning i, for eksempel, tre-dimensionelle (3D) opfattelse19,20,21,22 eller okulær svar til visuel indgang under interocular undertrykkelse23,24,25. For eksempel, er øjenbevægelser blevet fundet for at afsløre ubevidste behandling uden subjektive opfattelse under kontinuerlig flash undertrykkelse23. Kliniske visuelle forskere kan bruge evnen til at spore begge øjne under dichoptic præsentation at undersøge okulær sygdomme, der påvirker de to øjne asymmetrisk, for eksempel, til at overvåge de monokulare og kikkert visuelle forvridninger forekommer i amblyopi26 og maculopathy27.
Vi beskrev for nylig en setup1 , der giver mulighed for en kombination af høj kvalitet video-baserede eye tracking og dichoptic stimulation med lille begrænsning på størrelsen eller farven på stimuli, og vi vurderede dens ydeevne. Nedenfor vil vi opsummere konstruktionen og brugen af denne opsætning.

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

Præsentation af forskellige stimuli til de to øjne, dichoptic præsentation, er afgørende for undersøgelser, hvor 3D vision og interocular undertrykkelse. Der er en voksende litteratur på den unikke eksperimentelle værdi af pupil og oculomotor foranstaltninger, især for forskning på interocular undertrykkelse. Selv om opnåelse af eye-tracking foranstaltninger gavner således undersøgelser, der bruger dichoptic præsentation, hardware afgørende for dichoptic præsentation (f.eks. spejle) ofte forstyrrer høj kvalitet eyetracking, især når du bruger en video-baseret øje tracker. Vi beskrev for nylig en eksperimentel opsætning, der kombinerer en standard dichoptic præsentation system med et infrarødt øje tracker ved hjælp af infrarød-gennemsigtig spejle1. Opsætningen er kompatibel med standard monitorer og øjet bane, let at gennemføre, og overkommelige (størrelsesordenen US$ 1.000). Forhold til eksisterende metoder har fordelene ikke kræver særligt udstyr og poserer par grænser på arten og kvaliteten af den visuelle stimuli. Her giver vi en visuel guide til etablering og anvendelse af vores setup.

Efter kalibreringen beskrevet i protokollen, udførte vi kalibrering valideringsprocedure uden problemer med spejle på plads. Effektiviteten af metoden illustreres tydeligt af figur 5, som viser kameraets billede (ved hjælp af en forskning ende eye tracking system) med spejle på plads. De to sæt parallelle linjer langs deltagernes næse og linjer over brynene er kanterne af spejlene, men ansigtet er dog så klart inde i rammen, som uden er. Dette understr...

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

Vi har for nylig foreslået en metode, der giver mulighed for dichoptic visuelle stimuli præsentation og kikkert eye tracking samtidigt1. Nøglen er en kombination af et infrarødt øje tracker og de tilsvarende infrarød-gennemsigtig spejle. Håndskriftet indeholder en dybtgående protokol til startkonfiguration og daglige drift.

Hvordan man opbygger en Dichoptic præsentation System, der omfatter en øje Tracker

The presentation of different stimuli to the two eyes, dichoptic presentation, is essential for studies involving 3D vision and interocular suppression. ...
