Comparison of Visual Experiences and Display Preference in Viewing Stereoscopic 3D TV with Optically-corrected Active Shutter and Film Pattern Retarding Glasses

1 January 2011


Stereoscopic 3D viewing can be achieved by projecting images to the two eyes with shuttering and filtered polarization. One important difference between these two methods is that shutter glasses require a flat frontal surface whereas filtered polarizing glasses do not. They each pose different challenges to spectacle wearers who require both prescribed optical correction and 3D glasses to see 3D content. To investigate the effect of prescribed 3D glasses on viewing experiences, habitual spectacle wearers were recruited from Pacific University and Eulji University to test two types of 3D glasses: shutter glasses with attached curved spectacle correction (SG), and single unit film patterned retarding glasses (polarized) with curved (cFPR) frontal surfaces. Participants’ viewing symptoms, perceived immersion, and subjective evaluation of display quality were measured after 90-minute movie viewing. Curved FPR glasses were more comfortable to wear and less visually intrusive than SG glasses. As a result, wearing curved FPR was less tiring visually and physically. The magnitude of optical correction had little effect on perceived display quality and visual discomfort. Our findings generally indicate FPR glasses with incorporated optical correction are a better technology in affording better viewing comfort and resultant perceived display quality than active shutter glasses, regardless the magnitude of optical correction.
