  • QoE in Multimedia Systems – I started looking into the topics of QoS and QoE over a decade ago as part of my master’s project at Deutsche Telekom. A few years later, I completed my PhD on this topic at Lancaster University and continued exploring and modelling human factors in distributed multimedia systems for several resource projects. Currently I am interested in incorporating the context and awareness of user experience as a crucial element in system and networking designs. This includes: studying user perceptions of networked audio-visual content services; modelling the impact of network impairments and streaming mechanindex_clip_image006isms to the user experience of delivered content; and enabling QoE fairness in resource allocation using emerging network technologies (e.g., NFV and SDN).

  • Social TV and Data Mining –  Following the success of Lancaster P2P IPTV LivingLab, the team decided to move forward with a new social IPTV platform in order to support the research and experimentation of socio-cultural impact and new media technologies for the years to come. I led a small development team on this task and launched Vision Online TV (vision.lancs.ac.uk) in October 2013. The system serves 50+ live channels, 30,000+ VoD programmes, and a number of social features for thousands of registered users. The work is now supporting collaborative research such as “understanding the trends and contexts vision_logo_300x92of user journeys (e.g., browsing activities and patterns) to improve user engagement”.

  • Creative Media for Social Innovation – Inspired by our previous work in EPSRC FIRM project (Framework for Innovation and Research at MediaCityUK), I initiated a focus group with a few colleagues at Lancaster to study collaborative storytelling. We started with a system perspective and developed Storisphere (storisphere.com), an open narrative platform that enables the experimentation of creative and collaborative online story co-authoring using user generated audio-visual content. Later on, Storisphere also served as a core application in EC FP7 STEER project, where we experimented the fusion of online storying authoring, mobile applications, location-based services and social media for better user experience in live social events. storisphere_logo-400x140Follow this link for a user generated story from our user experiment at Silverstone British Grand Prix F1 in July 2014. Storisphere, along with other developments, is now part of my work on community awareness and social innovation.

  • Media Orchestration – Nowadays, our lives are surrounded by “smart” mobile devices. Orchestrating the media streams on multiple user devices (N screens) can deliver better and more immersive user experience and inspires new applications. This work involves research and developmentusecase of a media synchronization framework that facilitates the media stream orchestration. An example of the ground work is the modelling of user perception of cross-device non-synchronicity and media re-synchronization mechanisms through user experiments.
