How to Communicate Robot Motion Intent: A Scoping Review
Robots are becoming increasingly omnipresent in our daily lives, supporting
us and carrying out autonomous tasks. In Human-Robot Interaction, human actors
benefit from understanding the robot's motion intent to avoid task failures and
foster collaboration. Finding effective ways to communicate this intent to
users has recently received increased research interest. However, no common
language has been established to systematize robot motion intent. This work
presents a scoping review aimed at unifying existing knowledge. Based on our
analysis, we present an intent communication model that depicts the
relationship between robot and human through different intent dimensions
(intent type, intent information, intent location). We discuss these different
intent dimensions and their interrelationships with different kinds of robots
and human roles. Throughout our analysis, we classify the existing research
literature along our intent communication model, allowing us to identify key
patterns and possible directions for future research.Comment: Interactive Data Visualization of the Paper Corpus:

Children's peer assessment and self-disclosure in the presence of an educational robot
Research in education has long established how children mutually influence and support each other's learning trajectories, eventually leading to the development and widespread use of learning methods based on peer activities. In order to explore children's learning behavior in the presence of a robotic facilitator during a collaborative writing activity, we investigated how they assess their peers in two specific group learning situations: peer-tutoring and peer-learning. Our scenario comprises of a pair of children performing a collaborative activity involving the act of writing a word/letter on a tactile tablet. In the peer-tutoring condition, one child acts as the teacher and the other as the learner, while in the peer-learning condition, both children are learners without the attribution of any specific role. Our experiment includes 40 children in total (between 6 and 8 years old) over the two conditions, each time in the presence of a robot facilitator. Our results suggest that the peer-tutoring situation leads to significantly more corrective feedback being provided, as well as the children more disposed to self-disclosure to the robot.info:eu-repo/semantics/acceptedVersio
Design of a Huggable Social Robot with Affective Expressions Using Projected Images
We introduce Pepita, a caricatured huggable robot capable of sensing and conveying affective expressions by means of tangible gesture recognition and projected avatars. This study covers the design criteria, implementation and performance evaluation of the different characteristics of the form and function of this robot. The evaluation involves: (1) the exploratory study of the different features of the device, (2) design and performance evaluation of sensors for affective interaction employing touch, and (3) design and implementation of affective feedback using projected avatars. Results showed that the hug detection worked well for the intended application and the affective expressions made with projected avatars were appropriated for this robot. The questionnaires analyzing users’ perception provide us with insights to guide the future designs of similar interfaces
Socially Assistive Robots for Older Adults and People with Autism: An Overview
Over one billion people in the world suffer from some form of disability. Nevertheless, according to the World Health Organization, people with disabilities are particularly vulnerable to deficiencies in services, such as health care, rehabilitation, support, and assistance. In this sense, recent technological developments can mitigate these deficiencies, offering less-expensive assistive systems to meet users’ needs. This paper reviews and summarizes the research efforts toward the development of these kinds of systems, focusing on two social groups: older adults and children with autism.This research was funded by the Spanish Government TIN2016-76515-R grant for the COMBAHO project, supported with Feder funds. It has also been supported by Spanish grants for PhD studies ACIF/2017/243 and FPU16/00887
In Sync: Exploring Synchronization to Increase Trust Between Humans and Non-humanoid Robots
When we go for a walk with friends, we can observe an interesting effect:
From step lengths to arm movements - our movements unconsciously align; they
synchronize. Prior research found that this synchronization is a crucial aspect
of human relations that strengthens social cohesion and trust. Generalizing
from these findings in synchronization theory, we propose a dynamical approach
that can be applied in the design of non-humanoid robots to increase trust. We
contribute the results of a controlled experiment with 51 participants
exploring our concept in a between-subjects design. For this, we built a
prototype of a simple non-humanoid robot that can bend to follow human
movements and vary the movement synchronization patterns. We found that
synchronized movements lead to significantly higher ratings in an established
questionnaire on trust between people and automation but did not influence the
willingness to spend money in a trust game.Comment: To appear in Proceedings of the 2023 CHI Conference on Human Factors

Applications of Robotics for Autism Spectrum Disorder: a Scoping Review
Robotic therapies are receiving growing interest in the autism field, especially for the improvement of social skills of children, enhancing traditional human interventions. In this work, we conduct a scoping review of the literature in robotics for autism, providing the largest review on this field from the last five years. Our work underlines the need to better characterize participants and to increase the sample size. It is also important to develop homogeneous training protocols to analyse and compare the results. Nevertheless, 7 out of the 10 Randomized control trials reported a significant impact of robotic therapy. Overall, robot autonomy, adaptability and personalization as well as more standardized outcome measures were pointed as the most critical issues to address in future research
A Human-Robot Interaction Perspective on Assistive and Rehabilitation Robotics
Assistive and rehabilitation devices are a promising and challenging field of recent robotics research. Motivated by societal needs such as aging populations, such devices can support motor functionality and subject training. The design, control, sensing, and assessment of the devices become more sophisticated due to a human in the loop. This paper gives a human–robot interaction perspective on current issues and opportunities in the field. On the topic of control and machine learning, approaches that support but do not distract subjects are reviewed. Options to provide sensory user feedback that are currently missing from robotic devices are outlined. Parallels between device acceptance and affective computing are made. Furthermore, requirements for functional assessment protocols that relate to real-world tasks are discussed. In all topic areas, the design of human-oriented frameworks and methods is dominated by challenges related to the close interaction between the human and robotic device. This paper discusses the aforementioned aspects in order to open up new perspectives for future robotic solutions
