Task Models for Intention-Aware Systems

Intention-aware systems integrate aspects of context-aware and attentionaware systems for the identification and support of intention. Focusing intention is justified by the impact of intention on awareness and interaction with the world. Therefore, proactive user support mechanisms can be improved by including a representation of intention.

A framework for intention-aware systems is presented and discussed in detail
