Abstract
Darbs ir uzrakstīts angļu valodā uz 30 lapaspusēm. Tas satur 9 attēlus, 1 tabula un 26 atsauces uz literatūras avotiem. Tā kā trīsdimensiju tehnoloģijas strauji attīstās, pētījumos nepieciešams izvērtēt iekārtas un to mijiedarbību ar cilvēku. Pētījuma mērķis ir novērtēt uzvedības un neirofizioloģiskās iezīmes cilvēkiem, kuri veic uzdevumu izmantojot divas dažādas vizualizācijas: volumetrisko un stereoskopisko. Izmantojot elektroencefalogrāfiju tika reģistrēta smadzeņu aktivitāte un analizēti iegūtie potenciāli un neirālās svārstības. Spēcīgu dziļuma uztveres ietekmi ar abām vizualizācijas tehnoloģijām novēroja tikai vēlīnos uztveres procesos paura garozas reģionā. Turklāt ātrāks reakcijas laiks tika iegūts izmantojot volumetrisko ekrānu. Tādējādi var apgalvot, ka telpiskās informācijas apstrāde ir vienkāršāka izmantojot volumetrisko, nevis stereoskopisko vizualizācijas metodi. Šie rezultāti var tikt ņemti vērā šādu tehnoloģiju ieviešanai nākotnē.
The thesis is written in English on 30 pages. It contains 9 figures, 1 table, and 26 references. Since three-dimensional technologies are rapidly advancing, researchers have to study the matter and its interactions with people. The study aims to assess the behavioral and neurophysiological features of people that are completing a task with two different visualizations: volumetric and stereoscopic. Brain activity was recorded by electroencephalography and analyzed in event-related potentials and neural oscillations. A strong effect of depth perception for two visualizations was observed only in the late cognitive processes over the parietal cortical region. Moreover, faster response time was linked to a volumetric display. Thus, it was suggested that spatial information processing was easier with volumetric visualization rather than with stereoscopic. These findings may be considered in the future adoption of such technologies.
