Quadrant of Euphoria: A Crowdsourcing Platform for QoE Assessment
(NOTE: Sheng-Wei Chen is also known as Kuan-Ta Chen.)

Abstract
Existing QoE (Quality of Experience) assessment methods, subjective or objective, suffer from either or both problems of inaccurate experiment tools and expensive personnel cost. The panacea for them, as we have come to realize, lies in the joint application of paired comparison and crowdsourcing, the latter being a Web 2.0 practice of organizations asking ordinary, unspecific Internet users to carry out internal tasks. We present in this article Quadrant of Euphoria, a user-friendly, web-based platform facilitating QoE assessments in network and multimedia studies, with features low cost, participant diversity, meaningful and interpretable QoE scores, subject consistency assurance, and burdenless experiment process.
