A comparative study using an autostereoscopic display with augmented and virtual reality

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 childrenThis work was funded by the Spanish APRENDRA project (TIN2009-14319-C02).
