Abstract :
Study of the Influence of Characterization of
Audiovisual on Spectator
In a highly competitive environment, a primary
concern for those offering audiovisual services is ensuring
an optimal Quality of Experience (QOE) for the viewer.
Presently, QOE tends to be confined to evaluating the
perceived audiovisual quality (AVQ) delivered by the
system. This assessment typically involves testers rating
quality levels on scales after viewing and listening to AV
sequences processed through various technologies to be
assessed. These subjective tests adhere to protocols
recommended by the International Telecommunication
Union. However, the actual experience, encompassing
factors like fatigue or effort, isn't entirely captured by
these quality scores. A more comprehensive method that
evaluates not just the received AV quality but also
considers the broader quality of experience could better
depict how sound and image quality impact the viewer.
This study focuses on exploring an alternative approach
to current multimedia quality assessment methods in the
context of viewing/listening to 2D or 3D AV content. The
proposed method delves into QOE by analyzing
subjective indicators alongside physiological
(electrodermal activity, heart rate, peripheral cutaneous
temperature, blood volume pulse) and ocular indicators
(PERCLOS, blink duration/frequency, saccadic eye
movements, pupil diameter). Physiological and ocular
measurements offer advantages by bypassing the biases
inherent in subjective measures (such as
representativeness and scales) and by revealing
phenomena like fatigue or mental effort, possibly
triggered by audio and/or video degradations, which
significantly impact QOE. Two experimental protocols
were implemented to examine the viability of this
approach. Findings indicated that AV quality variations
influence subjective measures, exposing the inadequacy of
quality ratings to accurately represent this impact.
However, the influence of quality on physiological and
ocular measurements was less straightforward. Specific
factors related to certain attributes of test content, such as
dynamics or brightness, may have obscured or
diminished the observed effects of quality on these
measurements. Nonetheless, two physiological indicators
reacted to the presence of audio and/or video
degradations, particularly when compounded with other
factors (like 3D video or test duration effects).
