Abstract
We investigate audiences' subjective impressions of two
high-quality 3D stereoscopic films when viewed on a large projected
display (160-in diagonal). We further show that our results are repeatable
using TV-sized displays (50-in diagonal) and sites outside our laboratory.
The literature proposes a number of algorithms that aim to produce
high-quality stereoscopic depth in 3D films. Many of these algorithms
limit the stereoscopic depth to a defined depth budget, which can
be dynamically allocated through the course of a film. However, there
have been no detailed studies evaluating audiences' subjective
impressions of 3D films that utilize such algorithms, which is something
we seek to correct in this study. This study comprises an original
experiment and four differentiated replications, across which we vary
the film, display technology, and international location used. All
of these experiments implement a pre-test post-test quasi-experiment
design, in which participants were asked, before and after viewing
a 3D film, to rate their agreement with five statements concerning
3D films. These statements addressed the viewing experience, comfort,
naturalness, suitability to conveying complex information, and benefit
to learning associated with 3D displays. One of two possible films
were shown to each participant, both of which were produced using
our own stereoscopic depth control algorithms and have won national
or international awards, giving independent confirmation of their
quality. Our results indicate that audiences' responses to our
five statements change positively after viewing high-quality 3D films.
Furthermore, these results are repeatable for large and TV-sized displays,
as well as for locations outside our laboratory. We conclude that
it is important to produce high-quality content with a carefully controlled
depth budget in order to evoke positive reactions in audiences to
3D films.
