CACTUS Project Objectives
Model, design, optimize, and evaluate intelligence and context-awareness of an i-DEA device:
• The interaction between an intelligent device and its user• to carry out specific tasks as a trusted assistant• Taking communication context into account• USEr-Terminal interaction work package
• The trade-offs and optimizations in computing and communications:• information processing and communications amongst neighboring
devices in an ad-hoc fashion, • taking usage context into account• TERMInal-NETwork interaction work package

CACTUS UseT Illustrated (2)
Research questions addressed:• Electronic assistant that is trusted by user• Electronic assistant that is consistent across
platforms and environments• Electronic assistant that adapts itself to user’s
context - User context: task, situation, activity, mood,
experience, history- System context: resources of network and
device, application’s needs, connectivity, …• Electronic assistant has a model of its user and
preferences• Electronic assistant learns from the user’s actions

CACTUS TermiNet Illustrated (2)
Research questions addressed:
• System dynamically adapts routing in ad-hoc network depending on changing topology
• System optimizes QoS and democratic resource usage in ad-hoc networks
• Application level knows about underlying ad-hoc behavior and optimizes high-end application (media streaming)
• System uses a “context grid” to represent “communications and computing conditions history”

Deliverables 2002-2004
• Scientific output: • Papers and Ph.D. Theses• Design rules • Functional descriptions and Algorithms for
interaction/intelligent/network software components
• Simulation of ad-hoc network and media streaming
• Platform using off-the-shelf components for testing user interfacing concepts
• Usability and Feasibility studies
