The Internet of Things – A New Frontier of Multimedia Research
Kien A. Hua
Department of Computer Science, University of Central Florida
ABSTRACT The Internet of things (IoT) with 34 billion connected devices by 2020 will generate more ‘big data’ than ever. While Cloud Computing has been a viable solution for processing and analyzing very large volumes of data, dealing with billions of live data sources continuously feeding from all “corners” of the Internet would make it a serious bottleneck for IoT analytics in the cloud. In particular, on-demand video streaming already takes up 70% of Internet traffic. Non-stop streaming of IoT data will add substantially more stress on the Internet if IoT applications are not deployed responsibly. In this presentation, we discuss potential solutions for this emerging challenge as video streaming and IoT streaming coalesce. We re-examine conventional wisdom in network design and consider a new concept called traffic deduplication. We present a Deduplication Overlay Network (DON) that shows congestion can surprisingly be turned into advantage. Another great IoT challenge is due to ‘thing’ heterogeneity (i.e., the diversity of cameras and sensors) and a new computation model is needed for heterogeneous data stream processing. We discuss this capability in an IoT architecture based on a Boolean abstraction. A Boolean query-processing framework is also presented as a potential standard approach for applications to share IoT infrastructure. These features are part of ThingStore, an online ecosystem for development and deployment of IoT applications. While an IoT environment fusing human and machine intelligence opens up a host of new opportunities, the human teams may be overwhelmed trying to keep up with massive amount of real-time information. This calls for new communication and collaboration tools to enable the human teams to deal with information overload in real-time decision making. Tabletop, a virtual multimedia conferencing system, is one such environment to support teamwork in an IoT-enabled human-cyber workplace. The team members can not only share and discuss multimedia information, but also co-operate on IoT devices as they collaborate. A short video will be presented to demonstrate this Tabletop system.

Breaking The Glass Wall Between Users And Computers
Telecooperation, Technische Universität Darmstadt
ABSTRACT The introduction of IBM’s “Computer Terminal” 3270 and later of the VT100 by Digital Equipment in the 1970es triggered the wide-spread use of display-centric human computer interaction. The touch screens used in billions of smartphones and tablets worldwide bear witness of the latest and most ubiquitous phase of this era – will this be the last globally resounding success of computer displays? The main reason why this era will sooner or later be superseded is the fact that displays erect a glass wall between users and the information (as well as apps) they are coping with – may it be multimedia content or other data of all sorts.
But how can that glass wall be broken? Which are the promising technologies for the“era after the glass wall era” and what is their state of the affairs? Which interaction concepts, metaphors, and concrete user interface elements do these alternative technologies suggest?Which parts are still missing — or must be further advanced before we can finally say good-bye to the glass wall? Are there additional challenges beyond those pertaining toHuman Computer Interaction that must be addressed? After revisiting the main stages of the “glass wall era”, the talk will attempt to answer these questions.

The ‘u’ in Multimedia stands for humans
Vrije Universiteit Amsterdam and Fellow, CWI Amsterdam
ABSTRACT During the past half-decade, the study of multimedia has slowly transformed from creating, storing, transporting and rendering multiple media objects to analyzing the content of (mostly) visual objects. In this process, intelligence has migrated to machines and the human creator/compiler/manipulator and viewer of media content has become largely irrelevant. Although media content often contains encapsulated human emotion, it is now studied as if it contained only inanimate objects. It is time to bring the human back in the multimedia loop.
This talk will present an overview of the role of the human in creating, storing, selecting and consuming media. In each of these areas, we look at what human intelligence can add to the process of creating and consuming engaging experiences. We also consider the role of machines that can learn to adapt some of these tasks.
Taking examples from several aspects of media processing, the talk will provide a forward-looking overview of where we’ve come from and where we are likely to be going in the creation and consumption of media experiences in the next decade.
