Viewer experience with stereoscopic 3D television in the home

Stereoscopic 3D television (S3D TV) is now available in the home. However, little published information is available on viewer use or experience. In this study, 120 people from 29 households were given a new TV (active or passive stereoscopic 3D, or conventional 2D) and reported on their television viewing and other screen use on a near-daily basis over 8 weeks. People reported enjoying S3D TV and cinema more than TV and cinema in general, but enjoying S3D video games less than video games in general. S3D TV and video games were both associated with an increased, though still low (∼10%) level of adverse effects, such as headache and eyestrain. I speculate that this may be because video games present a particularly strong conflict between vergence and accommodative demand.
