The aim of the project is to assess the impact
of technologically innovative ways of delivering still and moving
images over networks on users and their interaction experience. We
use a 3-dimensional approach to media quality assessment, considering
task performance, user acceptance and user cost. Depending on the
assessment questions, we collect a combination of quantitative and
qualitative data. We use a range of innovative data collection methods,
such as physiological measurements and eyetracking data. The project
specifically focusses on identifying elements in images, video and
web pages on which users' attention is likely to be focussed. This
will knowledge can be exploited in image coding and Quality of Service
(QoS) management.
