Abstract: This paper introduces a prototype test-bed for triggering
sensory effects like light, wind, or vibration when presenting
audiovisual resources, e.g., a video, to users. The ISO/IEC MPEG is
currently standardizing the Sensory Effect Description Language (SEDL)
for describing such effects. This language is briefly described in the
paper and the test-bed that is destined to evaluate the quality of the
multimedia experience of users is presented. It consists of a video
annotation tool for sensory effects, a corresponding simulation tool,
and a real test system. Initial experiments and results on determining
the color of light effects from the video content are reported.
