An academic led a lab-based research, involving 433 viewers of ages from 4 to 82 years, in which participants were asked to watch Toy Story in either 2-D or 3-D (S3D) and report on their viewing experience. The objective of the study was to investigate visual discomfort in relation to 3-D display technologies, as well as to determine the impact of people’s preconceptions on their experience of 3D TV. It’s no secret that the format hasn’t taken off in the way many had anticipated.
