Paper Abstract

This study was designed to compare a new, autostereoscopic, 'glasses-free' three-dimensional screen with a passive glasses three-dimensional screen, and a two-dimensional imaging system. An objective analysis consisting of two experiments was conducted. The first experiment was designed to assess depth perception. Both 3-D imaging systems were compared to each other and a 2-D imaging system. A statistically significant difference existed between the 2-D screen and both of the 3-D screens (p less than 0.001). There was no statistical difference found between the 'glasses-free' 3-D screen and the passive glasses 3-D screen in either experiment. The second experiment was task oriented designed to compare the new, 'glasses-free' 3-D imaging screen with the passive glasses 3-D screen. In this inanimate setting, the task of passing a needle and suture through a series of hoops was performed faster with the passive glasses 3-D screen but this difference was not statistically significant. Conclusion: The 3-D screens clearly produce more accurate assessment of the depth than the 2-D screen. The new, 'glasses-free' 3-D screen produced comparable results to the established passive glasses 3-D screen.
