Advances in display devices are facilitating the integration of stereoscopic visualization in our daily lives. However, autostereoscopic visualization has not been extensively exploited. In this paper, we present a system that combines Augmented Reality (AR) and autostereoscopic visualization. We also present the first study that compares different aspects using an autostereoscopic display with AR and VR, in which 39 children from 8 to 10 years old participated. In our study, no statistically significant differences were found between AR and VR. However, the scores were very high in nearly all of the questions, and the children also scored the AR version higher in all cases. Moreover, the children explicitly preferred the AR version (81%). For the AR version, a strong and significant correlation was found between the use of the autostereoscopic screen in games and seeing the virtual object on the marker. For the VR version, two strong and significant correlations were found. The first correlation was between the ease of play and the use of the rotatory controller. The second correlation was between depth perception and the game global score. Therefore, the combinations of AR and VR with autostereoscopic visualization are possibilities for developing edutainment systems for children.
In this paper, we present a system that combines Augmented Reality and autostereoscopic visualization. We also report a study for comparing different aspects using an autostereoscopic display and a common display, in which 44 children aged from 8 to 10 years old have participated. From our study, statistically significant differences were found between both displays for the depth perception and for the sense of presence. Several correlations have also been found when children used the autostereoscopic display. In our study, the sense of presence is closely related with the depth perception; and the overall score of the game was also closely related with the depth perception and the sense of presence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
