description

Maģistra darbs uzrakstīts angļu valodā uz 32 lappusēm. Tas satur 15 attēlus un ir atsauces uz 37 literatūras avotiem. Strauji attīstoties trīsdimensiju (3D) vizualizācijas tehnoloģijai ir nepieciešams precīzi novērtēt cilvēka spēju pielāgoties tai. Šādos pētījumos plaši tiek izmantots EEG. Pētījuma mērķis bija izpētīt smadzeņu aktivitātes īslaicīgās izmaiņas, skatoties uz volumetriskiem attēliem un salīdzinot ar anaglifa 3D attēlu aplūkošanu. Uzdevums bija noteikt tuvāk esošo apli starp četriem projicētiem apļiem. Smadzeņu aktivitātes signālu reģistrēšanai tika izmantots EEG. Izsaukto potenciālu P300 komponentē darba slodzes ietekmē netika novērotas būtiskas izmaiņas. Būtiskas izmaiņas tika konstatētas tikai alfa viļņos Pz un P4 apgabalos. Salīdzinot ar stereoskopisko anaglifa 3D ekrānu, izsauktie potenciāli bija lielāki analifa metodē. Tika novērota arī beta un gamma viļņu pieaugums anaglifa 3D attālu aplūkošanā.
