Distributed and Interactive Systems
Leader of the group Distributed and Interactive Systems (DIS): Pablo Cesar.
The group focuses on modeling and controlling complex, collections of media objects (including real-time media and sensor data) that are interactive and distributed in time and space. The group’s fundamental interest is in understanding how the various notions of ‘time’ influence the creation, distribution and delivery of complex content in a customizable manner. The main challenges addressed by the group are:
- Understanding dynamic media composition: facilitating ‘on demand’ temporal compilations based on the dynamic and time-variant constraints for the social sharing of personal media and the development of content for education.
- Understanding user responses: providing mechanisms for monitoring and modeling user affinity and engagement to real-time events (performances, lectures) and to shared media. Such mechanisms need to ensure privacy.
- Modeling ‘time’ in multimedia documents: defining languages for the coordinated presentation of temporal objects within container documents.
- Application steering of quality of service and quality of experience: defining languages and control policies for improving user and network experience based on user steering.
Currently, the group focuses on the following activities, primarily funded by our two ongoing EU-funded projects (FP7/STREP Vconect and FP7/IP REVERIE):
- Quality of Experience: development of a software test platform that allows to evaluate how different aspects of network performance and media affect the quality of video communication.
- Immersive Real-Time Communication: the group develops mechanisms for 3D tele-presence in virtual and real worlds. This work includes novel compression algorithms that can handle live-captured mesh geometry, a streaming component for transmission and synchronization, and an engine that can autonomously reason and react to gestures and emotions.
- Social media and creativity: developing new user paradigms that manage engagement-based access to media content. The group studies sensor-based and direct manipulation as paradigms for collecting information on social affinity with media.
