Visual search tasks are mainly test methods of user performances for electronic visual displays, which was
usually used to assess the subjective quality of the visual display terminal. This study investigated the effect of different
3D styles on static 3D/2D visual search performance. A 2 (search environment: 3D versus 2D)× 2 (display styles: 3D
polarization versus 3D switch) within-subject factorial design was used in this experiment. The visual search contents
included static 3D/2D visual search performance, which the search target was hexagonal pyramid and the background
was pentagonal pyramid. The experiment task was to find out one hexagonal pyramid from many five pyramid in a
trial. The experiment was carried out in two 47-inch screen televisions and their matching 3D glasses. As the 47-
inch screen televisions, one was a typical 3D polarization television, which used LG display panel; the other was a
typical 3D switch television, which used the Samsung’s display panel. Sixteen subjects participated in this experiment.
The search time and accuracy of each participant were recorded. The difference in search performance between 3D
polarization television condition and 3D switch television condition was not significant whereas that between static 3D
visual search and 2D visual search condition was significant. Post hoc comparisons found that the search time under
the 2D environment was significantly longer than the search time under the 3D environment. Those results revealed
that search performance was sensitive to search environment and the performance was not sensitive to 3D display
styles. The obtained results could be a reference for deciding the visual search efficiency on different 3D display styles. |
