Özet:

Stereoscopic displays provide 3D vision usually with the help of additional equipment such as shutter glasses and head gears. As a new stereoscopic display technology, autostereoscopic 3D Displays provide 3D vision without additional equipment. Previous studies of depth and distance estimation with autostereoscopic displays indicate the users do not exhibit better performance in 3D. Yet, they claim 3D displays provide higher immersiveness. In this study, perception of the angle of a 3D shape is investigated by comparing 2D, 3D and Real perception cases. An experiment is conducted using an autostereoscopic 3D display. Forty people have participated in the experiment. They were asked to estimate the vertex angle and draw the projections of the object from two different viewpoints. It is found that users can better estimate the angles on a cone when viewed from the top on an autostereoscopic display. This may contribute positively to 3D understanding of the scene. Results revealed that participants make more accurate angle estimation in autostereoscopic 3D displays than in traditional 2D displays. In general, the participants’ angle drawings were slightly higher than their angle estimations. Moreover, the participants overestimated 35, 65 and 90 degree angles and underestimated 115 degree angle in autostereoscopic 3D display.
