Interoperable affective context collection using MPEG-21

The vision of the MPEG-21 standard is to specify a multimedia framework for the transparent delivery and consumption of multimedia content across a wide range of networks and devices. The user plays an important role in this framework. Therefore the optimization of the user experience is of uttermost importance. Context needs to be effectively collected and utilized to optimize this experience and MPEG-21 provides the necessary tools to do so. However, the efficient combination of these tools in order to create a context collection framework, remains an issue which is not tackled by the MPEG-21 standard. This paper proposes a framework, which incorporates affective context collection by combining several parts of the standard, as such creating an interoperable context-aware system.
