- Stéphane Marchand-Maillet - "Mining Networked Media Collections"
Multimedia data management has significantly evolved, in parallel with the changing usage of the WWW as a multimedia consumption platform. The ease of creation, storage, and consumption has however pinpointed and highlighted issues on the quality of access of multimedia data. Whereas generating content is a low-cost operation and is thus widely genralised, providing accessible handles to that content via annotation, tagging or other description operations is a costly process and therefore generally skipped, ignored or, at best minimized. The effect is scaled by the growing number of users, as content generators or content consumers. As a result, huge masses of poorly accessible multimedia data lie within the Web, with the risk of mapping a large portion of it onto a large distributed storage of hardly accessible data. The further interlinking of users into social networks and communities however offers a unique opportunity to make the data accessible and reusable at reasonable cost. Media items are not isolated or solely connected by a declared similarity. They may be inter-connected by their respective relationships with users, either as consumed or created items. This forms the so-called networked media, an immense collection of multimedia items immersed into a network of active users, organised into communities.
It is then a challenge to relate every user or group (community) action to multimedia content. In other words, every action may be seen as a semantic interpretation of the involved content and it is critical to be able to capture and preserve this knowledge to improve further and later access.
In this talk, I will discuss and present how networked media may be enriched and accessed by exploting, from several perspectives, the semantic implicit work made by users and communities. I will address the problems of mining this networked media, opposing static and dynamic contexts, personalised and generic perspectives. Concrete illustrations will be provided troughout the discussion.
Stéphane Marchand-Maillet has founded and is heading the Viper group (http://viper.unige.ch) in the Department of Computer Science at University og Geneva. His research is directed towards multimedia information retrieval with emphasis on Multimedia Content Abstraction, ie attaching semantic information to multimedia documents at cheapest cost. In particular, he is interested in all aspects related to multimedia information mining and retrieval and smooth acquisition of knowledge by enhancing user or group interaction.
He has recently been appointed as Chair of the Technical Committee 12 of the International Association for Pattern Recognition (IAPR-TC12, ``Multimedia and Visual Information Systems'', http://www.iapr-tc12.org). He was the general co-chair of the ACM International Conference on Image and Video Retrieval (ACM-CIVR 2009, http://www.civr2009.org). He is also the general co-chair of the International Conference of the ACM-SIG on Information Retrieval in 2010 (ACM-SIGIR 2010, http://www.sigir2010.org).
- Nuria Oliver - "Wearable Physiological Monitoring on Mobile Phones"
Wearable health monitoring devices have attracted increasing interest in recent years, both in research and industry. The ability to continuously monitor physiological signals is of particular importance for the world's increasingly aging and sedentary population, whose health has to be assessed regularly or monitored continuously. It has been estimated that a third or more of the 78 million baby boomers and 34 million of their parents may be at risk for the development of devastating diseases including cardiovascular disease, stroke and cancer. Fortunately, presymptomatic testing could save millions of these lives -and dollars- in the coming decades, according to experts. Wearable physiological monitoring devices are a critical component in preventive medicine where they will play an increasingly important role in the years to come. In addition, a sedentary lifestyle is a major underlying cause of death, disease, and disability. Unfortunately, levels of inactivity are high -and keep increasing- in virtually all developed and developing countries. The World Health Organization (WHO)1 has estimated that 60 to 85% of all adults are sedentary or nearly so. Physical inactivity is the cause of approximately 2 million deaths every year. Fortunately, technology can play a very important role to address the reality of an aging, sedentary population. However, there are still technical, legal and societal obstacles that need to be tackled before these wearable devices are ready for general use. For example, these devices need to be non-intrusive, easy to use, comfortable to wear, efficient in power consumption, privacy compliant, with very low failure rates and high accuracy in triggering alarms, especially if used for diagnostic purposes. In this talk, I will describe our experience in developing wearable real-time health monitoring systems on mobile phones. In particular, I will present two prototypes that explore the impact of real-time physiological monitoring in the daily life of users: (1) HealthGear to monitor users while they are sleeping and automatically detect sleep apnea events; and (2) MPTrain/TripleBeat, a mobile phone-based system that encourages users to achieve specific exercise goals.
- Alex Jaimes - Human-centered computing project: a media arts perspective
Computing is changing people´s lives in unexpected ways, having an impact not just on how we communicate with one another but also on what resources we have access to. From that perspective, computing has become essential to human livelihood, impacting our day-to-day as well as development in general. In spite of these advances, however, computing technologies are difficult to use and alienate a large portion of the population. In this presentation, I will talk about basic concepts in HCC and focus on the role of the arts. I will describe my own art projects (photography, video, performance & interactive art), and the work of other artists, highlighting the relationships between content, cultural context, and collaborative processes, and how this mix can impact computing in general and .
