Artificial Cognition for Social Human-Robot Interaction: An Implementation

© 2017 The Authors Human–Robot Interaction challenges Artificial Intelligence in many regards: dynamic, partially unknown environments that were not originally designed for robots; a broad variety of situations with rich semantics to understand and interpret; physical interactions with humans that requires fine, low-latency yet socially acceptable control strategies; natural and multi-modal communication which mandates common-sense knowledge and the representation of possibly divergent mental models. This article is an attempt to characterise these challenges and to exhibit a set of key decisional issues that need to be addressed for a cognitive robot to successfully share space and tasks with a human. We identify first the needed individual and collaborative cognitive skills: geometric reasoning and situation assessment based on perspective-taking and affordance analysis; acquisition and representation of knowledge models for multiple agents (humans and robots, with their specificities); situated, natural and multi-modal dialogue; human-aware task planning; human–robot joint task achievement. The article discusses each of these abilities, presents working implementations, and shows how they combine in a coherent and original deliberative architecture for human–robot interaction. Supported by experimental results, we eventually show how explicit knowledge management, both symbolic and geometric, proves to be instrumental to richer and more natural human–robot interactions by pushing for pervasive, human-level semantics within the robot's deliberative system

Information and communication technology solutions for outdoor navigation in dementia

INTRODUCTION: Information and communication technology (ICT) is potentially mature enough to empower outdoor and social activities in dementia. However, actual ICT-based devices have limited functionality and impact, mainly limited to safety. What is an ideal operational framework to enhance this field to support outdoor and social activities? METHODS: Review of literature and cross-disciplinary expert discussion. RESULTS: A situation-aware ICT requires a flexible fine-tuning by stakeholders of system usability and complexity of function, and of user safety and autonomy. It should operate by artificial intelligence/machine learning and should reflect harmonized stakeholder values, social context, and user residual cognitive functions. ICT services should be proposed at the prodromal stage of dementia and should be carefully validated within the life space of users in terms of quality of life, social activities, and costs. DISCUSSION: The operational framework has the potential to produce ICT and services with high clinical impact but requires substantial investment

Federated Embedded Systems – a review of the literature in related fields

This report is concerned with the vision of smart interconnected objects, a vision that has attracted much attention lately. In this paper, embedded, interconnected, open, and heterogeneous control systems are in focus, formally referred to as Federated Embedded Systems. To place FES into a context, a review of some related research directions is presented. This review includes such concepts as systems of systems, cyber-physical systems, ubiquitous computing, internet of things, and multi-agent systems. Interestingly, the reviewed fields seem to overlap with each other in an increasing number of ways

New Alterities and Emerging Cultures of Social Interaction

Globalization has generated increased societal heterogeneity and awakened interest of a new kind in social cohesion and integration. But globalization is not the only contemporary process to give rise to societal hybridization. Two other such processes - much less attended to in the theoretical debate but no less problematic as regards social integration - are societal ageing and robotization. Drawing on statistical estimates, this paper begins by assessing the relevance of these new processes of hybridization. The predictions in question indicate that in the near future, everyday interaction, not just with cultural strangers and 'intelligent' machines, but also with people suffering from dementia, will be an omnipresent phenomenon, confronting our societies with types and degrees of alterity never before encountered. Whereas contact with cultural strangers is to some extent familiar (though not yet taken as standard), interaction with intelligent technological devices and dementia sufferers represent new forms of alterity for which most societies have not yet established routines of conduct. This paper gives a detailed account of a number of empirical studies showing how new forms of hybrid interaction and cooperation evolve out of repeated contact with each of the three alterities. With this groundwork in place, the paper then attempts to identify not only the ways in which routines may develop out of interaction with the three alterities but also the trends towards, and prerequisites for, the emergence of a new culture of cooperation and interaction

A biologically inspired architecture for an autonomous and social robot

Lately, lots of effort has been put into the construction of robots able to live among humans. This fact has favored the development of personal or social robots, which are expected to behave in a natural way. This implies that these robots could meet certain requirements, for example, to be able to decide their own actions (autonomy), to be able to make deliberative plans (reasoning), or to be able to have an emotional behavior in order to facilitate human-robot interaction. In this paper, the authors present a bioinspired control architecture for an autonomous and social robot, which tries to accomplish some of these features. In order to develop this new architecture, authors have used as a base a prior hybrid control architecture (AD) that is also biologically inspired. Nevertheless, in the later, the task to be accomplished at each moment is determined by a fix sequence processed by the Main Sequencer. Therefore, the main sequencer of the architecture coordinates the previously programmed sequence of skills that must be executed. In the new architecture, the main sequencer is substituted by a decision making system based on drives, motivations, emotions, and self-learning, which decides the proper action at every moment according to robot's state. Consequently, the robot improves its autonomy since the added decision making system will determine the goal and consequently the skills to be executed. A basic version of this new architecture has been implemented on a real robotic platform. Some experiments are shown at the end of the paper.This work has been supported by the Spanish Government through the project called “Peer to Peer Robot-Human Interaction” (R2H), of MEC (Ministry of Science and Education), the project “A new approach to social robotics” (AROS), of MICINN (Ministry of Science and Innovation), the CAM Project S2009/DPI-1559/ROBOCITY2030 II, developed by the research team RoboticsLab at the University Carlos III of Madrid

We The People Politics: The Populist Promise of Deliberative Public Work

In this Kettering Foundation report, Harry Boyte argues that it is crucial to recover and expand on a politics of deliberation and public work, with deep roots in the populist tradition, if Americans are to re-create civic agency and turn around the sense that we are losing control over our collective future. Civic agency politics, involves people's capacities to work collectively and reflectively across differences to cope with common problems and to build a democratic life together, capacities long of central concern to the Kettering Foundation. Such populist politics has formed an important -- if now partly forgotten -- alternative both to state-centered technocratic approaches and to the unbridled market in American history, stretching from farmers' self-education and cooperative movements of the 19th century to efforts to build educational cultures of civic learning and empowerment in our time. We the People politics returns us to the insight of the Constitutions' Preamble, that "we the people" create government as a meeting ground and an instrument of our common life, neither the problem nor the solution to our challenges. In We the People politics citizens play central roles as co-creators of democracy, rather than appearing only in supporting roles as volunteers, consumers, victims, voters, or protestors

Consciosusness in Cognitive Architectures. A Principled Analysis of RCS, Soar and ACT-R

This report analyses the aplicability of the principles of consciousness developed in the ASys project to three of the most relevant cognitive architectures. This is done in relation to their aplicability to build integrated control systems and studying their support for general mechanisms of real-time consciousness.\ud To analyse these architectures the ASys Framework is employed. This is a conceptual framework based on an extension for cognitive autonomous systems of the General Systems Theory (GST).\ud A general qualitative evaluation criteria for cognitive architectures is established based upon: a) requirements for a cognitive architecture, b) the theoretical framework based on the GST and c) core design principles for integrated cognitive conscious control systems
