Exploratory Study on User's Dynamic Visual Acuity and Quality Perception of Impaired Images
In this paper we assess the impact of head movement on user's visual acuity
and their quality perception of impaired images. There are physical limitations
on the amount of visual information a person can perceive and physical
limitations regarding the speed at which our body, and as a consequence our
head, can explore a scene. In these limitations lie fundamental solutions for
the communication of multimedia systems. As such, subjects were asked to
evaluate the perceptual quality of static images presented on a TV screen while
their head was in a dynamic (moving) state. The idea is potentially applicable
to virtual reality applications and therefore, we also measured the image
quality perception of each subject on a head mounted display. Experiments show
the significant decrease in visual acuity and quality perception when the
user's head is not static, and give an indication on how much the quality can
be reduced without the user noticing any impairments.Comment: 6 pages, 5 figure
