Homesickness in University Students: The Role of Multiple Place Attachment.

The transition to college or university can lead to the challenge of adapting to a new setting. Homesickness has been frequently investigated as a potential negative consequence of relocation. This study analyzed the role of multiple place attachment in the development of homesickness among university students. The study used a multicausal framework. Situational, personality, and environmental psychological variables were considered. Different factors of a person’s personality were associated with vulnerability to homesickness. In addition, multiple place attachment and vulnerability to homesickness impacted the homesickness felt by students.

MONITORING ELDERLY PEOPLE WITH THE ROBOCARE DOMESTIC ENVIRONMENT: INTERACTION SYNTHESIS AND USER EVALUATION

This article describes aspects of a fully implemented artificial intelligence (AI) system that integrates multiple intelligent components to actively assist an elderly person at home. Specifically, we describe how constraint‐based scheduling technology is used to actively monitor a pattern of activities executed by the person and how detected temporal constraint violations are used to trigger meaningful and contextualized proactive interactions. This article also presents a psychological evaluation of the system focusing on elderly peoples attitudes, in which system acceptability, perceived utility, interaction modality, and emotional response are considered.

Proactive assistive technology: an empirical study

This paper analyzes the problem of evaluating elderly peoples perception of assistive robots and domotic environments. Specifically, we focus on aspects related to the modalities in which interaction can occur between an elder user and an assistive robotic agent. Our work benefits from the products of project ROBOCARE, namely, a domestic environment in which sensors, intelligent software components and a domestic robot provide a set of cognitive support services for the elder user. This paper analyzes a number of evaluation criteria in detail, specifically related to the robots aspect, the way in which it communicates with the user, and the perceived usefulness of its support services. Among these criteria, the paper proposes and reports an evaluation of the Proactive interaction modality (where the system takes the initiative) and On-demand interaction (in which the user explicitly requests a service). Users evaluate the On-demand support services in personal safety scenarios as particularly useful, and less so in scenarios which are not critical. The paper also provides a discussion which can be useful for the design of future assistive agents and robotic companions.

Evaluating Telepresence Robots in the Field

Most robotic systems are usually used and evaluated in laboratory setting for a limited period of time. The limitation of lab evaluation is that it does not take into account the different challenges imposed by the fielding of robotic solutions into real contexts. Our current work evaluates a robotic telepresence platform to be used with elderly people. This paper describes our effort toward a comprehensive, ecological and longitudinal evaluation of such robots. Specifically, the paper highlights open points related to the transition from laboratory to real world settings. It first discusses some results from a short term evaluation performed in Italy, obtained by interviewing 44 healthcare workers as possible clients (people connecting to the robot) and 10 older adults as possible end users (people receiving visits through the robot). It then describes a complete evaluation plan designed for a long term assessment also dwelling on the initial application of such methodology to test sites, finally it introduces some technical features that could enable a more robust real world deployment.

Assessing affective response of older users to a telepresence robot using a combination of psychophysiological measures

Telepresence robots can become a beneficial tool in home care assistance and rehabilitation services by helping elderly people to remain in their homes longer. They can represent an additional means to assist older adults and facilitate social interaction by creating a support network through which nursing staff and family members can collaborate. This article describes a feasibility study relatively to the use of such robots in the interaction with elderly people affected by Mild Cognitive Impairment (MCI). The paper aims at assessing the psychophysiological response of such users to the presence of the robotic platform in order to use it as an indication of the level of tolerance toward the platform. To this purpose, we have involved 9 healthy and 8 MCI older adults in the participation of an experimental study where they have been asked to perform repeated interactions with and without the telepresence robot. We based our analysis on a combination of psychological tests to assess anxiety, positive/negative effects of the interaction with the robot, and we performed physiological measurements (heart rate and heart rate variability) to obtain an objective measure of the actual psychological state. Results seem to suggest that the robot presence is satisfactorily tolerated by MCI and that it does not cause adverse effects in term of cardiovascular response, thus encouraging further investigation on telepresence robots for rehabilitation and care experimental studies.

Modeling users of crisis training environments by integrating psychological and physiological data

This paper describes aspects of a training environment for crisis decision makers who, notoriously, operate in highly stressful and unpredictable situations. Training such decision makers is the goal of PANDORA-BOX, a system which is able to teach a class of trainees representing different authorities that coordinate their interventions in critical situations. This paper dwells on the selection and modeling of the relevant human features that are shown to have an influence in decision making under crisis. The chosen features are used to create a trainee model on the basis of which the system adjusts the training exercises with the ultimate goal of maximizing the effectiveness of training. Trainees models are built by merging physiological and psychological data, and are represented by means of a timeline-based approach, a representation derived from planning technology. The infrastructure built for the trainee modeling constitutes the basis to assess the influence of specific variables (e.g., personality traits, self efficacy, stress and anxiety) on the performance of crisis managers during the training.

Long-Term Evaluation of a Telepresence Robot for the Elderly: Methodology and Ecological Case Study

Telepresence robotic systems are proposed in different contexts and specifically in the area of social robotics for assisting older adults at home. Similarly to other robotic systems, such robots are often designed and then evaluated in laboratory settings for a limited period of time. Lab-based evaluations present limitations because they do not take into account the different challenges imposed by the fielding of robotic solutions into real contexts for longer periods. In order to perform long-term experiments in real ecological settings it is very important to define a structured approach to assess the impact of a prolonged and constant use of the telepresence robot. This paper proposes a methodology in the area of elderly people support, called MARTA, for MultidimensionalAssessment of telepresenceRoboTfor olderAdults. It introduces the main variables of interest as well as the instruments and administration timeline for assessing relevant changes that may occur over time. MARTA is also validated in a one year-long case study during which a telepresence robot, called Giraff, has been deployed and iteratively assessed. The paper also provides remarks on the technology readiness and suggestions for its improvements.

Psychophysiological Methods to Evaluate User’s Response in Human Robot Interaction: A Review and Feasibility Study

Implementing psychophysiological measures is a worthwhile approach for understanding human reaction to robot presence in terms of individual emotional state. This paper reviews the suitability of using psychophysiological assessment in human-robot interaction (HRI) research. A review of most common psychophysiological parameters used in a controlled laboratory setting is provided and advantages and challenges of their utilization in HRI experiments are described. Exemplar studies focused on the implementation of psychophysiological measures for the evaluation of the emotional responses of the participants to the robots’ presence are described. Based on the reviewed literature, the paper also describes the results of our own research experience to make the most of the emerged recommendations. We planned and performed a study aimed at implementing psychophysiological measurements for assessing the human response of two groups of older adults (Healthy vs. Mild Cognitive Impairment subjects) towards a telepresence robot. Finally, the paper provides a summary of lessons learned across the field in using psychophysiological measures in HRI studies.

Telepresence Robot at Home: A Long-Term Case Study

The paper presents the current findings of an almost one-year case study of fielding the Giraff robot in a real home. The testing phase, which is still running, involves an older user, affected by Parkinsons disease, and his family, in the daily usage of a telepresence robot. Initial evidence show that Giraff has become part of the daily routine of the user being judged as a valuable tool for communication and close connection with the remote user. In general, the attitude of the user towards the aid remains stable being constantly positive over time. Nevertheless we also noted an impact of the technology robustness on user’s acceptance that will be further investigated in this continuation of the study.

Excite project: A review of forty-two months of robotic telepresence technology evolution

This article reports on the EU project ExCITE with specific focus on the technical development of the telepresence platform over a period of 42 months. The aim of the project was to assess the robustness and validity of the mobile robotic telepresence (MRP) system Giraff as a means to support elderly people and to foster their social interaction and participation. Embracing the idea of user-centered product refinement, the robot was tested over long periods of time in real homes. As such, the system development was driven by a strong involvement of elderly people and their caregivers but also by technical challenges associated with deploying the robot in real-world contexts. The results of the 42-months’ long evaluation is a system suitable for use in homes rather than a generic system suitable, for example, in office environments.
