Smart Conversational Agents for Reminiscence
In this paper we describe the requirements and early system design for a
smart conversational agent that can assist older adults in the reminiscence
process. The practice of reminiscence has well documented benefits for the
mental, social and emotional well-being of older adults. However, the
technology support, valuable in many different ways, is still limited in terms
of need of co-located human presence, data collection capabilities, and ability
to support sustained engagement, thus missing key opportunities to improve care
practices, facilitate social interactions, and bring the reminiscence practice
closer to those with less opportunities to engage in co-located sessions with a
(trained) companion. We discuss conversational agents and cognitive services as
the platform for building the next generation of reminiscence applications, and
introduce the concept application of a smart reminiscence agent
Attributions as Behavior Explanations: Toward a New Theory
Attribution theory has played a major role in social-psychological research. Unfortunately, the term attribution is ambiguous. According to one meaning, forming an attribution is making a dispositional (trait) inference from behavior; according to another meaning, forming an attribution is giving an explanation (especially of behavior). The focus of this paper is on the latter phenomenon of behavior explanations. In particular, I discuss a new theory of explanation that provides an alternative to classic attribution theory as it dominates the textbooks and handbooksāwhich is typically as a version of Kelleyās (1967) model of attribution as covariation detection. I begin with a brief critique of this theory and, out of this critique, develop a list of requirements that an improved theory has to meet. I then introduce the new theory, report empirical data in its support, and apply it to a number of psychological phenomena. I finally conclude with an assessment of how much progress we have made in understanding behavior explanations and what has yet to be learned
A Review of Verbal and Non-Verbal Human-Robot Interactive Communication
In this paper, an overview of human-robot interactive communication is
presented, covering verbal as well as non-verbal aspects of human-robot
interaction. Following a historical introduction, and motivation towards fluid
human-robot communication, ten desiderata are proposed, which provide an
organizational axis both of recent as well as of future research on human-robot
communication. Then, the ten desiderata are examined in detail, culminating to
a unifying discussion, and a forward-looking conclusion
Can Large Language Models Be Good Companions? An LLM-Based Eyewear System with Conversational Common Ground
Developing chatbots as personal companions has long been a goal of artificial
intelligence researchers. Recent advances in Large Language Models (LLMs) have
delivered a practical solution for endowing chatbots with anthropomorphic
language capabilities. However, it takes more than LLMs to enable chatbots that
can act as companions. Humans use their understanding of individual
personalities to drive conversations. Chatbots also require this capability to
enable human-like companionship. They should act based on personalized,
real-time, and time-evolving knowledge of their owner. We define such essential
knowledge as the \textit{common ground} between chatbots and their owners, and
we propose to build a common-ground-aware dialogue system from an LLM-based
module, named \textit{OS-1}, to enable chatbot companionship. Hosted by
eyewear, OS-1 can sense the visual and audio signals the user receives and
extract real-time contextual semantics. Those semantics are categorized and
recorded to formulate historical contexts from which the user's profile is
distilled and evolves over time, i.e., OS-1 gradually learns about its user.
OS-1 combines knowledge from real-time semantics, historical contexts, and
user-specific profiles to produce a common-ground-aware prompt input into the
LLM module. The LLM's output is converted to audio, spoken to the wearer when
appropriate.We conduct laboratory and in-field studies to assess OS-1's ability
to build common ground between the chatbot and its user. The technical
feasibility and capabilities of the system are also evaluated. OS-1, with its
common-ground awareness, can significantly improve user satisfaction and
potentially lead to downstream tasks such as personal emotional support and
assistance.Comment: 36 pages, 25 figures, Under review at ACM IMWU
A Survey of Personality, Persona, and Profile in Conversational Agents and Chatbots
We present a review of personality in neural conversational agents (CAs),
also called chatbots. First, we define Personality, Persona, and Profile. We
explain all personality schemes which have been used in CAs, and list models
under the scheme(s) which they use. Second we describe 21 datasets which have
been developed in recent CA personality research. Third, we define the methods
used to embody personality in a CA, and review recent models using them.
Fourth, we survey some relevant reviews on CAs, personality, and related
topics. Finally, we draw conclusions and identify some research challenges for
this important emerging field.Comment: 25 pages, 6 tables, 207 reference
Folk Theory of Mind: Conceptual Foundations of Social Cognition
The human ability to represent, conceptualize, and reason about mind and behavior is one of the greatest achievements of human evolution and is made possible by a āfolk theory of mindā ā a sophisticated conceptual framework that relates different mental states to each other and connects them to behavior. This chapter examines the nature and elements of this framework and its central functions for social cognition. As a conceptual framework, the folk theory of mind operates prior to any particular conscious or unconscious cognition and provides the āframingā or interpretation of that cognition. Central to this framing is the concept of intentionality, which distinguishes intentional action (caused by the agentās intention and decision) from unintentional behavior (caused by internal or external events without the intervention of the agentās decision). A second important distinction separates publicly observable from publicly unobservable (i.e., mental) events. Together, the two distinctions define the kinds of events in social interaction that people attend to, wonder about, and try to explain. A special focus of this chapter is the powerful tool of behavior explanation, which relies on the folk theory of mind but is also intimately tied to social demands and to the perceiverās social goals. A full understanding of social cognition must consider the folk theory of mind as the conceptual underpinning of all (conscious and unconscious) perception and thinking about the social world
The use of animated agents in eālearning environments: an exploratory, interpretive case study
There is increasing interest in the use of animated agents in eālearning environments. However, empirical investigations of their use in online education are limited. Our aim is to provide an empirically based framework for the development and evaluation of animated agents in eālearning environments. Findings suggest a number of challenges, including the multiple dialogue models that animated agents will need to accommodate, the diverse range of roles that pedagogical animated agents can usefully support, the dichotomous relationship that emerges between these roles and that of the lecturer, and student perception of the degree of autonomy that can be afforded to animated agents
