Currently available Web browsers are able to access and interpret these contents (i.e., Web videos, text, image, and audio). These contents stimulate only senses like audition or vision. Recently, it has been proposed to stimulate also other senses while consuming multimedia content through so-called sensory effects. These sensory effects aim to enhance the ambient experience by providing effects, such as, light, wind, vibration, etc. The effects are represented as Sensory Effect Metadata (SEM) which is associated to multimedia content and is rendered on devices like fans, vibration chairs, or lamps. In this paper we present a plug-in for the Mozilla Firefox browser which is able to render such sensory effects that are provided via the WWW. Furthermore, the paper describes two user studies conducted with the plug-in and presents the results achieved.}, keywords = {World Wide Web, MPEG-V, Subjective Quality Assessment, Sensory Effects, Quality of Multimedia Experience}, language = {EN}, pages = {12}, pdf = {https://www.itec.aau.at/bib/files/Waltl_TR11113.pdf}, publisher = {Alpen-Adria Universität Klagenfurt} } @TechReport{Vision2012_Timmerer2010, author = {Gatica-Perez, Daniel and Gottron, Thomas and Hahn, Martin and Hurley, Jim and Kompatsiaris, Yiannis and Larson, Marta and Takacs, Barnabas and Timmerer, Christian and Wortley, David}, institution = {European Commission}, title = {Vision 2020 on Networked Media and Web Applications}, year = {2011}, address = {Brussels, Belgium}, month = {nov}, language = {EN}, pages = {110} } @TechReport{Schojer2006, author = {Schojer, Peter and Böszörmenyi, Laszlo and Hellwagner, Hermann}, institution = {Institute of Information Technology ({ITEC}), Klagenfurt University}, title = {QBIX-G-A Transcoding Multimedia Proxy}, year = {2006}, address = {Klagenfurt, Austria}, month = {jan}, number = {TR/ITEC/05/2.11}, abstract = {An adaptive multimedia proxy is presented which provides (1) caching, (2) filtering, and (3) media gateway functionalities.
