Over the past years, telecommunications as a research area has grown far beyond pure communications engineering and covers today the entire economic value chain up to the end customer. As an appropriate reaction to both this general trend as well as related interests of our partner companies, a new core research activity on "Economic and User Aspects" has recently been added to the ftw. research portfolio. The strategic project SUPRA (Strategic Usability and Pricing Research Activity) is placed right within the center of this evolution, merging and expanding the already existing activities in the areas of usability, human interfaces for mobile multimedia, perceptual speech quality, and internet economics into a coherent and interdisciplinary framework.
Resorting to technological competence as the primary strength of ftw., SUPRA aims at enriching this perspective on telecommunications by selected user-centric and economic elements. This leads to a natural trichotomy of the project into technical work-packages which cover usability, technological and pricing aspects (with more detailed contents as sketched below). Within SUPRA, we have established the Human-TelecomSystems Interaction Laboratory (HTI Lab). It allows us to conduct live experiments at the ftw. premises. Moreover, close cooperation with related internal as well as European and international activities (e.g. B3-HIMM, B2/U1-Speech&More, P1-MONA, N0-High Performance Packet Networking, IST-MobyDick, ICQT, IST-Convivio etc.) yields an adequate embedding of SUPRA both in a local and an international research context.
The main research topics are:
Usability Aspects:
- Development of methods for usability design and usability evaluation in telecommunications
- Building of more usable interfaces for mobile multimedia communication
- Perceptual assessment of conversational/interactive multimedia (methodology and evaluations)
Technological Aspects:
- Speech pre-processing and denoising
- Architectures for distributed speech recognition
- Algorithms supporting spoken information retrieval
Pricing Aspects:
- Network Economics
- User-friendly market-managed pricing and charging mechanisms in heterogeneous environments
- Tariffs as links between QoS technology and user perception
