Towards an aspect weaving BPEL engine
This position paper proposes the use of dynamic aspects and
the visitor design pattern to obtain a highly configurable and
extensible BPEL engine. Using these two techniques, the
core of this infrastructural software can be customised to
meet new requirements and add features such as debugging,
execution monitoring, or changing to another Web Service
selection policy. Additionally, it can easily be extended to
cope with customer-specific BPEL extensions. We propose
the use of dynamic aspects not only on the engine itself
but also on the workflow in order to tackle the problems of
Web Service hot deployment and hot fixes to long running
processes. In this way, composing aWeb Service "on-the-fly"
means weaving its choreography interface into the workflow
Multi-Agent System (MAS) Applications in Ambient Intelligence (AmI) Environments
Proceedings of: 8th Conference on Practical Applications of Agents and Multi-Agent Systems (PAAMS`10). Salamanca (Spain), 28-30 April 2010Research in context-aware systems has been moving towards reusable and adaptable architectures for managing more advanced human-computer interfaces. Ambient. Intelligence (AmI) investigates computer-based services, which are ubiquitous and based on a variety of objects and devices. Their intelligent and intuitive interfaces act as mediators through which people can interact with the ambient environment. In this paper we present an agent-based architecture which supports the execution of agents in AmI environments. Two case studies are also presented, an airport information system and a railway information system, which uses spoken conversational agents to respond to the user's requests using the contextual information that includes the location information of the user.This work has been partially supported by CICYT TIN2008-06742-C02-02/TSI, CICYT TEC2008-06732-C02-02/TEC, SINPROB, CAM MADRINET S-0505/TIC/0255 and DPS2008-07029-C02-02Publicad
An architecture and technology for Ambient Intelligence Node
The era of separate networks is over. The existing technology leaders are preparing a big change in recreation of environment around us. There are several faces for this change. Names like Ambient Intelligence, Ambient Network, IP Multimedia Subsystem and others were created all over the Globe. Regardless of which name is used the new network will combine three main functional principles---it will be: contextual aware, ubiquitous access and intelligent interfaces unified network.
Within this thesis two major aspects are defined. First, the definition of the Ambient Intelligence Environment concept is presented. Secondly the architecture vectors for the technology are named. A short overview of the existing technology is followed by details for the chosen technology---FPGA. The overall specifications are incorporated in the design and demonstration of a basic Ambient Intelligence Node created in the System on the Chip (SoC) FPGA technology
Designing Attention-Centric Notification Systems: Five HCI Challenges
Through an examination of the emerging domain of cognitive systems, with a
focus on attention-centric cognitive systems used for notification, this document explores
the human-computer interaction challenges that must be addressed for successful
interface design. This document asserts that with compatible tools and methods, user
notification requirements and interface usability can be abstracted, expressed, and
compared with critical parameter ratings; that is, even novice designers can assess
attention cost factors to determine target parameter levels for new system development.
With a general understanding of the user tasks supported by the notification system, a
designer can access the repository of design knowledge for appropriate information and
interaction design techniques (e.g., use of color, audio features, animation, screen size,
transition of states, etc), which have analytically and empirically derived ratings.
Furthermore, usability evaluation methods, provided to designers as part of the integrated
system, are adaptable to specific combinations of targeted parameter levels. User testing
results can be conveniently added back into the design knowledge repository and
compared to target parameter levels to determine design success and build reusable HCI
knowledge.
This approach is discussed in greater detail as we describe five HCI challenges
relating to cognitive system development: (1) convenient access to basic research and
guidelines, (2) requirements engineering methods for notification interfaces, (3) better
and more usable predictive modeling for pre-attentive and dual-task interfaces, (4)
standard empirical evaluation procedures for notification systems, and (5) conceptual
frameworks for organizing reusable design and software components.
This document also describes our initial work toward building infrastructure to
overcome these five challenges, focused on notification system development. We
described LINK-UP, a design environment grounded on years of theory and method
development within HCI, providing a mechanism to integrate interdisciplinary expertise
from the cognitive systems research community. Claims allow convenient access to
basic research and guidelines, while modules parallel a lifecycle development iteration
and provide a process for requirements engineering guided by this basic research. The
activities carried out through LINK-UP provide access to and interaction with reusable
design components organized based on our framework. We think that this approach may
provide the scientific basis necessary for exciting interdisciplinary advancement through
many fields of design, with notification systems serving as an initial model.
A version of this document will appear as chapter 3 in the book Cognitive
Systems: Human Cognitive Models in Systems Design edited by Chris Forsythe, Michael
Bernard, and Timothy Goldsmith resulting from a workshop led by the editors in summer
2003. The authors are grateful for the input of the workshop organizers and conference
attendees in the preparation of this document
Designing interactive ambient multimedia applications: requirements and implementation challenges
Ambient intelligence opens new possibilities for interactive multimedia, leading towards applications where the selection, generation and playback of multimedia content can be directed and influenced by multiple users in an ambient sensor network. In this paper, we derive the basic requirements for a flexible infrastructure that can support the integration of multimedia and ambient intelligence, and enable rapid tailoring of interactive multimedia applications. We describe our implementation of the proposed infrastructure, and demonstrate its functionality through several prototype application
