Mulsemedia: State of the art, perspectives, and challenges
Mulsemedia-multiple sensorial media-captures a wide variety of research efforts and applications. This article presents a historic perspective on mulsemedia work and reviews current developments in the area. These take place across the traditional multimedia spectrum-from virtual reality applications to computer games-as well as efforts in the arts, gastronomy, and therapy, to mention a few. We also describe standardization efforts, via the MPEG-V standard, and identify future developments and exciting challenges the community needs to overcome
The role of human influence factors on overall listening experience
Overall listening experience (OLE) is an evaluation measure specific to the evaluation of audio, which aims to include all
possible factors that may influence listeners’ ratings of stimuli. As with quality of experience in general, OLE ratings are user
dependent. Previous research has shown that listeners can be categorised by how much their OLE is influenced by content
and technical audio quality respectively. In this article, we expand on this knowledge by investigating correlations between
a range of human influence factors and the degree to which a listener is influenced by content and technical audio quality.
This was done by means of a web-based experiment involving 58 participants from a range of backgrounds. Results show that
listener type is significantly correlated with a range of psychographic variables and that the attitudinal measure ‘competence’
is the most suitable variable to be used as a predictor of listener type. As well as these results having direct applications such
as tailoring systems and services to the needs of specific user groups, the results presented add to the understanding of how
human factors can influence quality of experience in general

A mulsemedia framework for delivering sensory effects to heterogeneous systems
Investigating the impact of sensory effects on the Quality of Experience and emotional response in web videos
Multimedia is ubiquitously available online with large amounts of video increasingly consumed through Web sites such as YouTube or Google Video. However, online multimedia typically limits users to visual/auditory stimulus, with onscreen visual media accompanied by audio. The recent introduction of MPEG-V proposed multi-sensory user experiences in multimedia environments, such as enriching video content with so-called sensory effects like wind, vibration, light, etc. In MPEG-V, these sensory effects are represented as Sensory Effect Metadata (SEM), which is additionally associated to the multimedia content. This paper presents three user studies that utilize the sensory effects framework of MPEG-V, investigating the emotional response of users and enhancement of Quality of Experience (QoE) of Web video sequences from a range of genres with and without sensory effects. In particular, the user studies were conducted in Austria and Australia to investigate whether geography and cultural differences affect users\u27 elicited emotional responses and QoE. 2012 IEEE
The quality of experience of next generation audio :exploring system, context and human influence factors
PhD ThesisThe next generation of audio reproduction technology has the potential to deliver
immersive and personalised experiences to the user; multichannel with-height loudspeaker
arrays and binaural techniques offer 3D audio experiences, whereas objectbased
techniques offer possibilities of adapting content to suit the system, context
and user. A fundamental process in the advancement of such technology is perceptual
evaluation. It is crucial to understand how listeners perceive new technology in
order to drive future developments. This thesis explores the experience provided by
next generation audio technology by taking a quality of experience (QoE) approach
to evaluation. System, context and human factors all influence QoE and in this thesis
three case studies are presented to explore the role of these categories of influence factors
(IFs) in the context of next generation audio evaluation. Furthermore, these case
studies explore suitable methods and approaches for the evaluation of the QoE of
next generation audio with respect to its various IFs. Specific contributions delivered
from these individual studies include a subjective comparison between soundbar and
discrete surround sound technology, the application of the Open Profiling of Quality
method to the field of audio evaluation, an understanding of both how and why environmental
noise influences preferred audio object balance, an understanding of how
the influence of technical audio quality on overall listening experience is related to
a range of psychographic variables and an assessment of the impact of binaural processing
on overall listening experience. When considering these studies as a whole,
the research presented here contributes the thesis that to effectively evaluate the perceived
quality of next generation audio, a QoE mindset should be taken that considers
system, context and human IFs.Engineering and
