Focus
The group's research is organized into the following key areas, which are reflected in our projects and publications.
1. Human-Computer Interaction (HCI)
- Human Factors and Interaction Design of ICTs
- Usability, Usable Security, User Research, (Participatory) ideation and iterative prototyping
- Social Computing, Technology and the cultural domain - “Culture over IP”
- Ubiquitous and mobile HCI
- Computer Supported Cooperative World
End User and Communication Ecosystem.
Our particular emphasis, however, is on the end user and her role within the communication ecosystem. Here, we deal for instance with intuitive interface and interaction design for mobile applications in the future world of ubiquitous telecommunications, but also with more fundamental questions concerning the future evolution of ICT towards a “digital humanism”.
This explicitly interdisciplinary approach results in the investigation of multi-faceted research questions, including:
Subjective Service Quality.
While the area of service quality has traditionally been dominated by the technocratic approach of Quality of Service (QoS), more recently the subjective concept of Quality of Experience (QoE) has been established successfully. We follow a strictly user-centric approach for QoE and aim at the determination of fundamental QoE laws for speech, video, multimedia and web applications, the derivation of the corresponding relationship with network-based QoS parameters, and novel schemes for QoE-based service charging.
Usable Security.
Also open questions in network and data security typically combine technical, economical and user-centric issues. Our specific interest focuses on the economical analysis of related market structures as well as the user acceptance of novel architectures, algorithms and interfaces aiming at an adequate, intuitive and pragmatic digital identity control.
Culture over IP.
We believe that the delivery and distribution of cultural content will become one of the most important tasks (and challenges) of the future Internet. Inspired by the rich musical tradition of Vienna, in this context we mainly focus on applications from the area of classical music, especially opera.
2. Networks and Network Security
- Internet of Things / Internet of People
- (Computer) Networks --- design, operation, and use
- IP-based Networking Technologies in Core and Access
- Network-based Information and Communication Economics (NICE)
IP-based Networking Technologies in Core and Access.
We investigate distributed algorithms for monitoring and controlling IP networks and services and develop novel approaches for traffic routing and priorisation both within and between core networks of different operators. Moreover we are researching new methods for the close coordination of remote access networks as well as techno-economic aspects of small cell networks (Wi-Fi/femto cells).
Network-based Information and Communication Economics (NICE).
Considering technical ICT systems from an explicit microeconomic perspective allows the employment of game theoretic methodologies for modeling all sorts of cooperation and competition scenarios in the corresponding ecosystem, as well as for describing the resulting consequences for value creation and charging, as well as corresponding regulatory aspects.
