Experience Aware Networking

Experience Aware Networking leverages novel network paradigms (i.e. Software Defined Networking) and the state-of-the-art of Quality of Experience (QoE) research to optimize the experience of users in adaptive media applications. Video is already the #1 traffic source in the Internet and new services are emerging rapidly, such as VR or AR. As a consequence, networks suffer from bottlenecks due too heavy traffic loads, too many users, or a combination of both. Current network resource allocation techniques, such as bitrate-fairness or client-based adaptation algorithms, do not translate in overall user experience optimization. We create QoE-aware models, optimization algorithms, and software prototypes with the aim of understanding how these applications scale and how network resources can be managed to improve the QoE of users.

Social IoT and Smart Textiles

We live in a society based on experiences. Whether we look at a commercial for a holiday destination or interact with social media, the consumer experience plays a crucial role in our behavior. Yet, it is surprising to see how little it is actually known about how consumers value these experiences. The high-end technical solutions for shaping experiences sharply contrast with the rather conventional mechanisms used to measure them. DIS explores the use of smart textiles and wearable sensors as a source for collecting reliable and quantified data about everyday life experiences. In particular, we are interested on better understanding social IoT in the environment of smart cities. Based on realistic testing grounds, collaborating with several commercial and academic partners, we have deployed our technology and infrastructure in places such as the National Theatre of China in Shanghai and the Amsterdam Dance Event in the Netherlands. Our approach is to seamless connecting fashion and textiles with sensing technology, and with the environment. The final objective is to create intelligent and empathic systems that can react to the audience and their experience.

Multi-Screen Media Production, Consumption and Sharing

Technological advances are resulting in a complex media ecosystem, in which streaming media can reach a variety of end-devices using a heterogeneous set of delivery methods. Such development allows ubiquitous media consumption, where users to consume digital content via a connected ecosystem of devices, whenever they want and wherever they are. Still many challenges remain at the production, distribution, and user levels. DIS is developing novel mechanisms for group-based consumption, enriching, and sharing of media content. This results in research breakthroughs such as production tools for facilitating “on demand” temporal media-based compilations for multi-screen consumption of media, optimization algorithms for ubiquitous rendering of media based on the user context and intention, and seminal works on secondary screens and social TV.

Quality of Experience

In Quality of Experience (QoE) we want to understand how the quality of a system or service affects the experience of users. When does a long delay in tele-communication disrupt the conversation and when do we not even notice at all? How much bandwidth does a videostream need that we really feel we are getting a better quality? It turns out, to understand the experience of users, taking personal and situational factors into account is as important as the actual quality of the system. Media consumption has become an ubiquitous part of life and if we want to optimize our systems understanding the interplay of situation, personality and system quality is a key requirement.
