A personal agent supporting ubiquitous interaction

2016

Technology revolution has been occurred rapidly over the last past thirty years According to the moor’s law power of microprocessors double every eighteen months. And also a parallel increase can be observed in some other technological sectors such as network communication, bandwidth, storage, capacity. These remarkable trends make us to predict that in future computer will become considerably smaller, cheaper and more pervasive. These result a creation of small things that can access the internet in order to optimize their intended purpose. It gives birth to new technology trend called “Ubiquitous computing”. Ubiquitous computing is an emerging technology that brings new dimensions to distributed computing. It uses a wide variety of smart, ubiquitous devices throughout an individual’s working and living environment. When it comes to ubiquitous computing, mobile objects and mobile agents are forerunners. Mobile agents are considered a very interesting and emerging technology to deve...

Our research is at the crossroads of two main complementary areas: agents for intelligent systems and human-computer interactions. The prospect of highly natural interfaces, in which interaction between user and computer is mediated by lifelike agents, is currently one of the major steps leading to the acceptance of relevant and practical agents system by people. In this paper we illustrate our approach which takes into account both the evolution of the user interface technology and the emergence of ubiquitous computing in order to propose a proactive adaptive assistance through an agent named X-CAMPUS (eXtensible Conversational Agent for Multichannel Proactive Ubiquitous Services). It aims to assist proactively user in her daily tasks thanks to its ability to perceive the state of the environment and to communicate effectively according to the user's current situation.

Being everywhere, going anywhere and accessing at any time. Ubiquitous computing is the paradigm of service omnipresence, device heterogeneity, calm technology application and user satisfaction. Therefore, the success of ubiquitous systems depends on the mobile computing nature. In this paper, we introduce the application of intentional mobile agents in the systematic development of ubiquitous systems. These agents are commonly used to perform specific activities in dedicated servers, such as the content adaptability based on the ubiquitous profiles information. It demands context-awareness, which can be improved by exploring critical interactions among mobility, smart-spaces and cognitive-based autonomous entities. Finally, we show how our proposal has been appropriately applied to a ubiquitous system from the e-commerce domain.

A major challenge of Ambient Intelligence lies in building middleware that can ease service implementation through allowing the application developer to emphasize only the service logic. In this paper we describe the architecture of an Ambient Intelligence system established in the scope of the European research project CHIL (Computers in the Human Interaction Loop). CHIL aims at developing and realizing computer services that are delivered to humans in an implicit and unobtrusive way. The framework presented here supports the implementation of human-centric context-aware applications. This includes the presentation of the sensors used in CHIL spaces, the mechanisms employed for controlling sensors and actuating devices, as well as the perceptual components and the middleware approach for combining them in the scope of applications. Special focus lies on the design and implementation of an agent based framework that supports “pluggable” service logic in the sense that the service developer can concentrate on coding the service logic independently of the underlying middleware. Following the description of the framework, we elaborate on how it has been used to support two prototype context-aware human centric and non-obtrusive services.

The idea of ubiquitous computing (ubicomp) is an environment dominated by computing and communication devices of different scales which are seamlessly integrated to the users activities. The features of ubiquitous computing environments require developers to face important challenges in dealing with the complexities associated to the development of ubiquitous computing systems. This thesis describes a middleware to facilitate developers to manage some of the complexities associated with the development of ubiquitous computing systems by means of the use of autonomous agents, which enable ubiquitous computing technology to respond to users' particular conditions and demands. Autonomous agents were used to implement the desirable features of ubiquitous computing systems and for enhancing the interactions of the users with the environment. The contributions of this thesis focus on presenting the functional requirements of autonomous agents for implementing ubiquitous computing systems and the agent SALSA middleware, which was created with the aim of facilitating the implementation and evolution of ubicomp systems. Finally, this thesis provides evidence of the SALSA flexibility for enabling the progressive development of ubicomp systems.

Agent-based systems have long been recognized as a candidate technology for delivering autonomous and autonomic behaviors; however it is only recently that their usage has been explored in a new, emerging generation of systems that involve embedding agents on computationally challenged devices. The prudent harnessing of such agents can offer software engineers additional tools in their efforts to construct and deploy innovative mobile services or to realize practical smart environments. However, documented results of comprehensive evaluations of mobile services conducted in real world environments are rare; evaluations of systems that harness the agent paradigm are almost non-existent. This paper seeks to remedy this deficiency. It is hoped that the results of this study will encourage researchers to reflect further on the potential and implications of harnessing the intelligent agent paradigm in the broad Ambient Intelligence domain, from a software engineering perspective, and as an enabler of intelligent interaction.

This paper details the DigitalFriend, a new form of Personal Assistant Agent for building complex personal systems, often incorporating simple services, including web services, but also including sophisticated intelligent software agents. The blueprint for the DigitalFriend is the ShadowBoard agent architecture, itself inspired by the Theory of Sub-Selves from Analytical Psychology. It is a 24-hour, 7-day (24x7) system, and uses a role-oriented message lens to filter and highlight the information emerging from the various sub-agents making up a user's Digital Friend, prioritized for their attention. Various agent types are available including one that wraps SOAP and WSDL web services, and another that retrieves RSS feeds. In addition to providing an umbrella technology over an array of individual services and functionality, the DigitalFriend can logically orchestrate numerous agents, with a built-in constraint logic language (CoLoG) interpreter, forming new synergies of functionality (i.e. mash-ups), often unforeseen by the individual service providersall configurable from within a GUI interface, aimed at end-users.

In this paper we outline a vision, methodology and architectural design for creating an ambient environmental intelligence composed of a ubiquitous computing environment made up of scaleable, networked agent-based artefacts, which has arisen from our work in the EU’s Disappearing Computer Initiative (DCI) eGadgets project. We discuss the research challenges involved, particularly those relating to embedding intelligent agents into artefacts, and include a prototype design of one such artefact based agent. We describe a practical ubiquitous computing test-bed environment (the iDorm) which combines a number of artefact based agents, several different networks and provides a common protocol to act as a gateway between the different sensors and effectors. In addition we introduce a web/wap based iDorm emulation and visualisation system that acts as an interface to this ubiquitous computing environment, allowing users to control and monitor the agent-based artefacts.

Autonomous Agents and Multi-agent Systems, 2010

Multi-agent software architectures have gained in popularity due to their beneficial behavior in designing and implementing sophisticated applications. However, current approaches in implementing such architectures have led to application-specific, non-scalable implementations which limit the reusablity and improvement of the whole architecture. Moreover, these attempts lack features to enhance the user experience, thus slowing the adoption of the resulting services. In this paper we describe a fully-fledged multi-agent architecture covering a large variety of preferred features including capabilities of 'plugging' ubiquitous services, servicing mobile users, interconnecting remote similar architectures and interfacing with advanced software components such as knowledge bases. This framework exploits a wide-range of context-aware components making it essentially context-aware, allowing for the development of ubiquitous context-aware human-centric services, which are the focus of our research. To illustrate the flexibility of this architectural framework, we present four services which were built using this architectural paradigm by different development teams and elaborate on their overall behavior.
