This paper describes concepts, design, implementation, and performance evaluation of a 3D-based user interface for accessing Ambient Intelligence Environments (AmIE). The generic interaction model of the described work addresses some major challenges of Human-Environment-Interaction such as cognitive overload and manual device selection, loss of user control, missing system image or over-automation...
This paper presents a lightweight but effective mastersender-driven multiple parent approach for online video adaptation and streaming to heterogeneous clients. The proposed design facilitates the cooperation of participating clients for improving the utilization of the spare resources in an overlay. Our design uses standard H.264/AVC video streams. It enables peers to contribute both CPU and bandwidth...
In the era of universal multimedia access (UMA), applications like video conferencing, surveillance and streaming are challenged by the multiplicity of devices. Since adaptation is the newly applied practice for digital video content customization, in this demo, we present a simple approach to adapt H.264 videos, in the compressed domain, for heterogeneous devices and mobile environments. Our approach...
