Mobile Apps as Personal Assistant Agents: the JaCa-Android Framework for programming Agents-based applications on mobile devices
No full textA relevant application domain for agent-based software is given by mobile and wearable applications. In this context, the impressive progress of technologies in the last decade makes it possible to explore the use of agent-oriented programming languages and frameworks based on cognitive architectures, such as the Belief–Desire–Intention (BDI) one. Accordingly, in this paper we provide a comprehensive description of the JaCa-Android approach, a framework based on the JaCaMo platform that allows for designing and programming smart mobile apps using cognitive agents based on the BDI architecture and the Agents & Artifacts environment conceptual model. In these years, the framework has been applied in real-world projects and application domains, and extended and evolved accordingly. The aim of the paper is to report our experience about designing and programming mobile apps as personal assistant agents, as well as to discuss in detail the architecture of the framework
Towards a mobile augmented reality system for emergency management: The case of SAFE
No full textThe impressive development of wearable computing and augmented/mixed reality technologies that has been occurring in recent years allows for devising ICT systems that can bring a disruptive innovation in how emergency medical operations take place. In this paper the authors describe first explorations in that direction, represented by a distributed collaborative system called SAFE (Smart Augmented Field for Emergency) for teams of rescuers and operators involved in a rescue mission. SAFE is based on the integration of wearable computing and augmented reality technologies with intelligent agents and multi-agent systems
Applying Telemedicine for Stroke Remote Diagnosis: the TeleStroke System
Full text linkIn the healthcare context, one of the branches where we assisted in a remarkable evolution in the last decade is telemedicine. Enhancements in the ICT landscape have driven this evolution toward the current state of the art. Nonetheless, despite its undeniable benefits – both for patients health and local health authorities economics – nowadays, telemedicine has not been fully adopted as much as it could be. The recent COVID-19 pandemic has further strengthened the role and importance of telemedicine nowadays, also highlighting the existing gaps. This paper describes a telemedicine-oriented software system called TeleStroke to support the remote diagnosis of a possible stroke, applied to an Hub&Spoke healthcare organisation
Pervasive and Connected Digital Twins – A Vision for Digital Health
Full text linkHealthcare is a main domain where digital twins are being explored and applied. Following a healthcare 4.0 perspective, in this paper we discuss a vision in which digital twins are pervasively used to digitalize any strategic assets of a health organization. We start from introducing a specific real-world case study – concerning trauma management – and then we broaden the discussion identifying some main points and challenges of a wider vision
Towards the Web of Augmented Things
No full textIn this paper we envision and discuss the idea of the Web of Augmented Things (WoAT). The idea is about the integration of Web of Things with Augmented Worlds, i.e. distributed software systems augmenting the physical space with virtual entities and holograms in an Augmented Reality perspective, eventually coupled with smart things that are part of the same environment
An extension of AgentSpeak(L) and Jason tailored to programming and software development
No full textAgent programming languages like AgentSpeak(L) -- and Jason, as its modern extension/implementation -- have features that make them interesting for software development and general-purpose programming, besides AI problems. A main one is the level of abstraction, that eases the design and development of concurrent, reactive, distributed applications. At the same time, being not developed for general-purpose programming and software development in mind, they typically miss elements that are important for that purpose. These weaknesses can negatively impact on their adoption beyond the agent-oriented programming community. Accordingly, in this paper we discuss some features extending the basic model provided by AgentSpeak(L)/Jason, with the purpose of improving its adoption for programming and software development. Such extensions are shown in practice using a Jason extension called Jona
The JaCa-Android Framework for Programming BDI-Based Personal Agents on Mobile Devices
No full textNowadays, smart mobile applications are a medium allowing more and more for developing (part of) complex software systems, featuring interactive behaviour and exhibiting different degrees of autonomy and flexibility. In agents and MAS literature, Personal Assistant Agents represent the area that mostly can benefit from the availability of frameworks allowing for easily developing native agent-based applications able to exploit features offered by smart mobile and wearable devices. This paper discusses the JaCa-Android framework, a version of JaCaMo redesigned to natively run over mobile devices equipped with Google Android operating system. Exposing native features to observe and perceive the real-time user context and act accordingly, the framework is oriented in particular to the development of smart mobile apps as BDI-based personal assistant agents offering a proper layer of abstraction for this specific purpose
Developing agent-based pervasive mixed reality systems: The mirage framework
No full textThe impressive development of smart technologies is reducing the gulf between the physical and the digital matter, between what is real and what is virtual. Recent technological advances in the Mixed Reality (MR) context – both tools, such smart-glasses/visor, and software frameworks/libraries – are bringing new opportunities for research in agents and Multi-Agents Systems (MAS), in particular to explore their application in the design and development of mixed reality based smart intelligent environments that we can call augmented worlds (AWs). The goal of this demo is to present a first prototype of a framework called MiRAgE to build agent-based pervasive mixed reality software systems, incrementally showing its potentialities and proposed abstractions for the design of such class of systems
A model and platform for building agent-based pervasive mixed reality systems
No full textIn agent literature, a partially unexplored area is related to the integration of ever-wider opportunities offered by technologies such as Mixed Reality (MR) and Augmented Reality (AR). In this paper we present a framework called Augmented Worlds (AW), which provides a model and a technological support to develop a broad spectrum of agent-based AR/MR systems. Distinguishing key features of the approach include: bi-directional augmentation, support for existing cognitive agent technologies, support for developing open multi-user environments. In the paper, we describe first the conceptual model on which the framework is based, and then a concrete architecture and prototype implementation. Two case studies about real-world applications – an augmented museum and an augmented harbour – engineered with the framework are finally discussed
Mashing up the physical and augmented reality: TheWeb of Augmented Things Idea
No full textAlong with Internet of Things (IoT), Augmented Reality (AR) and Mixed Reality (MR) are going to be an important ingredient for the design and development of future smart environments, in particular in enterprise contexts. The vision of Web of Augmented Things (WoAT) - discussed in this paper - aims at exploiting the Web of Things to enable the development of open interoperable pervasive hybrid systems integrating IoT and AR/MR, mashing up both physical Things and augmented, AR-based ones
