In this world, devices equipped with simple intelligence and the abilities to sense, communicate, and act will be unremarkable features of our world. We will expect the car to warn us of hazards, track our location and provide timely route advice. We will speak to simple machines and hold conversations with more complex systems, such as intelligent homes that will help us monitor conditions, track routine tasks, and program the behaviour of the heat, the lights, the garden watering and the entertainment centre. Analogous systems at work will make simple decisions in our stead ranging from scheduling meetings to negotiating for common services over the web. Such systems will also acquire, and adapt to our preferences over time. In sum, we will come to view simple software intelligence as an ambient feature of our environment. The infrastructure for ambient intelligence is fast coming on line. Computational resources are cheap and becoming cheaper, while ubiquitous network access has started to appear. Market forces will soon produce applications. We take the view that ambient intelligence is imminent and inevitable, and that the time is ripe to take stock. This workshop will provide that opportunity by gathering researchers in a variety of AI subfields together with representatives of commercial interests to explore the technology and applications for ambient intelligence. Areas of interest: include, but are not limited to the following: - human interaction with autonomous systems - modelling complex environments (smart homes, hospitals, transportation, museums, etc) - self-adaptive systems - context awareness - responsive/active architecture - applications (health, defence, etc.) - innovative applications of AI to Ambient Intelligence - agent-based approaches to AmI - traditional relevant areas of AI (knowledge representations, reasoning about actions, spatio-temporal reasoning, planning, uncertainty, learning, belief revision, vision, etc.) This workshop will complement previous events, such as the International Conference on Smart Homes and Telecare, the AAAI 2005 Spring Symposium Workshop on Persistent Assistants and the European Symposium on Ambient Intelligence. This workshop differs in that it will focus on the special relevance of AI technology to the goals of Ambient Intelligence, and on the most likely avenues for practical application. AITAmI'07 will provide an open forum based on a variety of presentations: research papers, keynotes, panels and industrial demos. This event will provide a continuation to AITAmI'06 held during ECAI'06. Submission Details: Authors wishing to participate as speakers in this event should format their papers following the same formatting guidelines than for the main conference. More details of the submission process will be given in the web page of the event. Publications: all papers accepted will be published in the proceedings of the event. A volume will be published after the event with extended and improved versions of selected papers. Co-Chairs: J.C. Augusto (U. of Ulster, UK) jc.augusto 'at' ulster.ac.uk D.

D., Sims, C. R., Fu, W.-T., & Schoelles, M. J. (2006). The soft constraints hypothesis: A rational analysis approach to resource allocation for interactive behavior. Psychological Review, 113(3), 461-482. (abstract follows below) Our concern for resource allocation is something that arose in the context of trying to determine the right set of tradeoffs between acquiring knowledge in-the-world versus retrieving knowledge from in- the-head in the context of our work in building ACT-R models of the Argus Prime task. (Note that this is not an ACTR or an Argus Prime paper. No ACTR or Argus Prime models are discussed or included in the current publication.) Although the current paper does not include an ACTR model, ACTR modelers might find our Ideal Performer Model interesting for some of the following reasons (in addition to the reasons that non-ACTR modelers might find the work interesting): We use a type of reinforcement learning, Q-learning, that (in our use of this technique) is formally guaranteed to optimize performance in terms of minimizing time. We pull out of ACTR several important components which we then embed in our Ideal Performer Model: We use the Rational Activation Theory of memory that has been the default memory for all ACTR models from 1.0 thru 6.0. We use this to provide retrieval times as well as probabilities for successful retrieval. From ACTR models of Blocks World (partially reported in Gray, W. D., Schoelles, M. J., & Sims, C. R. (2005). Adapting to the task environment: Explorations in expected value. Cognitive Systems Research, 6(1), 27-40) we pull out time estimates for perceptual- motor activity. Wayne ABSTRACT Soft constraints hypothesis (SCH) is a rational analysis approach that holds that the mixture of perceptual-motor and cognitive resources allocated for interactive behavior is adjusted based on temporal cost-benefit tradeoffs. Alternative approaches maintain that cognitive resources are in some sense protected or conserved in that greater amounts of perceptual-motor effort will be expended to conserve lesser amounts of cognitive effort. One alternative, the minimum memory hypothesis (MMH), holds that people favor strategies that minimize the use of memory. SCH is compared with MMH across 3 experiments and with predictions of an Ideal Performer Model that uses ACT-R?s memory system in a reinforcement learning approach that maximizes expected utility by minimizing time. Model and data support the SCH view of resource allocation; at the under 1000-millisecond level of analysis, mixtures of cognitive and perceptual-motor resources are adjusted based on their cost-benefit tradeoffs for interactive behavior. **Rensselaer**Rensselaer**Rensselaer**Rensselaer**Rensselaer** Wayne D.

I' am having some problems while using ACT-R compiled in Allegro CL 7 Trial, sometimes it is not able to access some functions when I'm using the Perception and Motors modules. I' ve just tried to make the ACT press a key with an open window. The module was activated, but a error occured. Is this problem associated to the Allegro's version (Trial in this case)? Thank you.

If you send me the details of your setup (OS, specific ACL version including whether it's with or without the IDE, and specific ACT-R version details from the load), the model you're trying to run, and the error and other details from the run then I should be able to help you determine why it's not working.
