The Role of Personality Factors and Empathy in the Acceptance and Performance of a Social Robot for Psychometric Evaluations

Research and development in socially assistive robotics have produced several novel applications in the care of senior people. However, some are still unexplored such as their use as psychometric tools allowing for a quick and dependable evaluation of human users’ intellectual capacity. To fully exploit the application of a social robot as a psychometric tool, it is necessary to account for the users’ factors that might influence the interaction with a robot and the evaluation of user cognitive performance. To this end, we invited senior participants to use a prototype of a robot-led cognitive test and analyzed the influence of personality traits and user’s empathy on the cognitive performance and technology acceptance. Results show a positive influence of a personality trait, the “openness to experience”, on the human-robot interaction, and that other factors, such as anxiety, trust, and intention to use, are influencing technology acceptance and correlate the evaluation by psychometric tests

What do humans feel with mistreated humans, animals, robots and objects? Exploring the role of cognitive empathy

The aim of this paper is to present a study in which we compare the degree of empathy that a convenience sample of university students expressed with humans, animals, robots and objects. The present study broadens the spectrum of elements eliciting empathy that has been previously explored while at the same time comparing different facets of empathy. Here we used video clips of mistreated humans, animals, robots, and objects to elicit empathic reactions and to measure attributed emotions. The use of such a broad spectrum of elements allowed us to infer the role of different features of the selected elements, specifically experience (how much the element is able to understand the events of the environment) and degree of anthropo-/zoomorphization. The results show that participants expressed empathy differently with the various social actors being mistreated. A comparison between the present results and previous results on vicarious feelings shows that congruence between self and other experience was not always held, and it was modulated by familiarity with robotic artefacts of daily usage

Does the personality of consumers influence the assessment of the experience of interaction with social robots?

In recent years, in response to the effects of Covid-19, there has been an increase in the use of social robots in service organisations, as well as in the number of interactions between consumers and robots. However, it is not clear how consumers are valuing these experiences or what the main drivers that shape them are. Furthermore, it is an open research question whether these experiences undergone by consumers can be affected by their own personality. This study attempts to shed some light on these questions and, to do so, an experiment is proposed in which a sample of 378 participants evaluate a simulated front-office service experience delivered by a social robot. The authors investigate the underlying process that explains the experience and find that cognitive-functional factors, emphasising efficiency, have practically the same relevance as emotional factors, emphasising stimulation. In addition, this research identifies the personality traits of the participants and explores their moderating role in the evaluation of the experience. The results reveal that each personality trait, estimated between high and low poles, generates different responses in the evaluation of the experience

Shopping with Voice Assistants: How Empathy Affects Individual and Family Decision-Making Outcomes

Artificial intelligence (AI)-enabled voice assistants (VAs) such as Amazon Alexa increasingly assist shopping decisions and exhibit empathic behavior. The advancement of empathic AI raises concerns about machines nudging consumers into purchasing undesired or unnecessary products. Yet, it is unclear how the machine’s empathic behavior affects consumer responses and decision-making outcomes during voice-enabled shopping. This article draws from the service robot acceptance model (sRAM) and social response theory (SRT) and presents an individual-session experiment where families (vs. individuals) complete actual shopping tasks using an ad-hoc Alexa app featuring high (vs. standard) empathic capabilities. We apply the experimental conditions as moderators to the structural model, bridging selected functional, social-emotional, and relational variables. Our framework collocates affective empathy, explicates the bases of consumers’ beliefs, and predicts behavioral outcomes. Findings demonstrate (i) an increase in consumers’ perceptions, beliefs, and adoption intentions with empathic Alexa, (ii) a positive response to empathic Alexa holding constant in family settings, and (iii) an interaction effect only on the functional model dimensions whereby families show greater responses to empathic Alexa while individuals to standard Alexa

Examining Social Robot Acceptability for Older Adults and People with Dementia

Social robots that aim to support the independence and wellbeing of older adults and people with dementia are being introduced into dementia care settings. However, the acceptability of robots varies greatly between people and the rate that robots are deployed into practice is currently low. This chapter defines robot acceptability and provides an overview of theoretical technology acceptance models. It reviews the empirical literature and identifies the individual and contextual factors that impact acceptability in relation to the needs of older adults and people with dementia, focusing on what potential robot users need to motivate them to accept robots into their everyday lives. Then the literature is discussed in the light of current discourses in gerontology, recommending what is needed to increase the acceptability of robots. The capacity of robots, to communicate in a human-like way needs to increase and robots need to be designed with in-depth end-user collaboration, to be person-centred and deployed in ways that enhance the strengths of people with dementia. Guidance for good practice in participatory design is provided. Longitudinal research that uses triangulated data from multiple sources. is recommended to identify the needs of individuals, significant others, and wider contextual factors

The Impact of Hotel Service Robot Appearance and Service Attributes on Customer Experience

In the past decade, an increasing discussion has taken place regarding the employment of hotel service robots. One critical issue is the impact service robots exhibit on customer experience. However, most of the existing studies focus on service robots’ technical functions or customer’s adoption behavior instead of customers’ psychological or attitudinal reactions toward the robot. Meanwhile, the emergence of humanoid robots has raised great attention from both researchers and industry practitioners. Humanlike features (e.g. facial expressions, emotions, and motions) inherently affect customer experience in a hotel environment. Nevertheless, limited literature exists in incorporating service robots’ anthropomorphism and service attributes into customer experience and perceived brand equity. Not many studies have included both the service robots’ traits and customers’ personality traits when assessing customer experience. Therefore, the purpose of the current study is to explore and understand the impact of service robots’ appearance, service efficiency, and service customization on customer experience interacting with the service robot in the context of a hotel front desk check-in service. Customers’ personality traits such as robot anxiety, technology readiness, and self-image congruity are also taken into consideration. This study also examines the influence of service robots’ appearance and service attributes on hotel customers’ perceptions toward the hotel brand equity. The current study used experiments and online surveys to test the theoretical model and the perception changes toward the hotel brand equity. Two samples of 220 and 161 hotel customers who have completed the check-in services in person in the past 12 months were recruited for Study 1 and Study 2, respectively. Pilot studies were conducted, and hypothetical scenarios were embedded in the online surveys. The results showed that hotel service robots’ appearance (extremely humanoid vs. humanoid vs. non-humanoid) did not lead to different customers’ experiences interacting with the service robot. Service efficiency was a significant factor while service customization was not in affecting customer experiences. Customers’ levels of technology readiness and self-image congruity exerted significant impacts on customer experiences. Moreover, customers did not show obvious perception changes before and after interacting with the hypothetical service robot. Theoretical and practical contributions were discussed

개발 초기 단계에서의 소셜 AI 개인비서 평가 모델 개발

학위논문(박사) -- 서울대학교대학원 : 공과대학 산업공학과, 2022.2. 윤명환.This dissertation aims to propose a user evaluation model to evaluate social AI personal assistants in the early stage of product development. Due to the rapid development of personal devices, data generated from personal devices are increasing explosively, and various personal AI services and products using these data are being launched. However, compared to the interest in AI personal assistant products, its market is still immature. In this case, it is important to understand consumer expectations and perceptions deeply and develop a product that can satisfy them to spread the product and allow general consumers to easily accept the product promptly. Accordingly, this dissertation proposes and validates a user evaluation model that can be used in the early stage of product development. Prior to proposing this methodology, main characteristics of social AI personal assistants, the importance of user evaluation in the early stage of product development and the limitations of the existing user evaluation model were investigated in Chapter 2. Various technology acceptance models and evaluation models for social AI personal assistant products have been proposed, evaluation models that can be applied in the initial stage of product development were insufficient, however. Moreover, it was found that commonly used evaluation measures for assessment of hedonic value were much fewer compared to measures for utilitarian value. These were used as starting points of this dissertation. In Chapter 3, the evaluation measures used in previous studies related to social AI personal assistant were collected and carefully reviewed. Through systematic review of 40 studies, the evaluation measures used in the past and limitation of related research were investigated. As a result, it was found that it was not easy to develop a prototype for evaluation, so it was possible to make the most of the products that have already been commercialized. In addition, all evaluation items used in previous studies were collected and used as the basis for the evaluation model to be proposed later. As a result of the analysis, considering the purpose of the social AI personal assistant, the role as supporting the user emotionally through social interaction with the user is important, but it was found that the evaluation measures related to hedonic value that are commonly used were still insufficient. In Chapter 4, evaluation measures that can be used in the initial stage of product development for social AI personal assistant were selected. Selected evaluation measures were used to evaluate three types of social robots and relationship among evaluation factors were induced through this evaluation. A process was proposed to understand to various opinions related to social robots and to derive evaluation items, and a case study was conducted in which a total of 230 people evaluated three social robots concept images using the evaluation items finally selected through this process. As a result, it is shown that consumers’ attitude toward products was built through the utilitarian dimension and the hedonic dimension. In addition, there is positive relationship between ease of use and utility in the utilitarian dimension, and among aesthetic pleasure, attractiveness of personality, affective value in the hedonic dimension. Moreover, it is confirmed that the evaluation model derived from this study showed superior explanatory power compared to the previously proposed technology acceptance model. In Chapter 5, the model was validated again by applying the evaluation measure and the relationship among evaluation factors derived in Chapter 4 to other products. 100 UX experts with expertise in the field of social AI personal assistants and 100 users who use the voice assistant service often, watched two concept videos of the voice assistant service to help users in the onboarding situation of mobile phones and evaluated these concepts. As a result of the evaluation, there is no significant difference in the evaluation results between the UX expert and the real user group, so the structural equation model analysis was conducted using all the data obtained from the UX expert and the real user group. As a result, results similar to those in Chapter 4 are obtained, and it is expected that the model could be generalized to social AI personal assistant products and applied for future research. This dissertation proposes evaluation measure and relationship among evaluation factors that can be applied when conducting user evaluation in the initial stage of social AI personal assistant development. In addition, case studies using social AI personal assistant products and services were conducted to validate it. With the findings of this study, it is expected that researchers who need to conduct user evaluation to clarify product concepts in the early stages of product development will be able to apply evaluation measures effectively. It is expected that the significance of this dissertation will become clearer if further research is conducted comparing the finished product of social AI personal assistants with the video type stimulus in the early stage of development.본 논문은 최근 빠르게 발전하고 있는 social AI personal assistant의 개발 초기 단계에 활용 가능한 사용자 평가 항목을 개발하고 평가 항목 간의 관계를 검증하는 것을 목표로 한다. 개인 디바이스의 발달로 인해, 각 디바이스에서 생성되는 데이터가 폭발적으로 증가하고 있고, 이를 활용한 개인용 AI 서비스 및 제품이 다양하게 제안되고 있다. 하지만 그 관심에 비해, social AI personal assistant 제품의 실제 시장은 아직 성숙하지 않은 단계이다. 이러한 상황에서 제품을 빠르게 확산시키고 일반 소비자들이 쉽게 제품을 수용할 수 있게 하기 위해서는, 소비자의 기대와 인식을 충분히 이해하고 그를 충족시킬 수 있는 제품을 개발하는 것이 중요하다. 이에 따라 본 연구에서는 제품 개발 초기 단계에 활용할 수 있는 사용자 평가 항목을 제안하고 평가 항목 간 관계를 도출하는 것을 목표로 한다. 먼저 2장에서는 social AI personal assistant의 특징, 제품 개발 초기 단계에서 이루어지는 사용자 평가의 중요성 및 기존 사용자 평가 모델의 한계점을 조사하였다. 기존에 기술 수용 모델 및 AI personal assistant 제품의 평가 모델들이 다양하게 제안되어 왔으나, 제품 개발 초기 단계에 활용할 수 있는 평가 모델은 부족하였고, 제품 전반을 평가할 수 있는 평가 모델의 부재로 대부분의 기존 연구에서는 두 가지 이상의 평가 모델을 결합, 수정하여 사용한 것을 알 수 있었다. 3장에서는 AI personal assistant 관련 기존 연구에서 활용된 평가 항목을 검토하였다. 총 40개의 연구를 리뷰하여, 기존에 활용되고 있는 평가 항목의 종류 및 한계점을 알아보았다. 그 결과, 평가를 위한 프로토타입 개발이 쉽지 않기에 이미 상용화된 제품들을 최대한 활용하는 것을 알 수 있었으며, 제품 전반을 평가한 사례는 부족함을 알 수 있었다. 또한 기존 연구들이 사용한 평가 항목을 모두 수집 및 정리하여 이후 제안할 평가 모델의 기반 자료로 활용하였다. 분석 결과, social AI personal assistant의 목적을 고려해보았을 때, 사용자와의 사회적 인터랙션을 통해 사용자의 감정적인 면을 채워주는 역할이 중요하지만, 공통적으로 활용하고 있는 감정적 가치 관련 평가 항목이 부족한 것으로 나타났다. 4장에서는 social AI personal assistant 제품 개발 초기 단계에서 활용 가능한 평가 항목을 수집 및 제안하고, 평가 항목을 활용하여 social robots을 평가한 뒤 이를 통해 평가 항목 간의 관계를 도출하였다. Social robots 관련 의견을 다양하게 청취하고 평가 항목을 도출하는 프로세스를 제안하였으며, 본 프로세스를 통해 최종 선정된 평가 항목을 이용하여, 총 230명이 세 가지 social robots 컨셉 영상을 평가하는 사례 연구를 진행하였다. 평가 결과, 제품에 대한 소비자 태도는 Utilitarian dimension과 Hedonic dimension을 통해 형성되었고, Utilitarian dimension 내 사용성 및 제품 효용성, Hedonic dimension에 포함되는 심미적 만족도, 성격의 매력도, 감성적 가치 각각은 서로 긍정적인 상관관계를 지님을 알 수 있었다. 또한 기존에 제안된 기술 수용 모델 대비 본 연구에서 도출한 평가 모델이 우수한 설명력을 보임을 확인하였다. 5장에서는 4장에서 도출된 평가 모델을 타 제품에 적용하여 모델을 다시 한번 검증하였다. 해당 분야에 전문성을 지닌 UX 전문가 100명 및 음성 비서 서비스를 실제 사용하는 실사용자 100명이, 휴대폰 온보딩 상황에서 사용자를 도와주는 음성 비서 서비스의 컨셉 영상 두 가지를 보고 컨셉에 대한 평가를 진행하였다. 평가 결과 UX 전문가와 실사용자 그룹 간에는 평가 결과에 유의미한 차이를 보이지 않았기 때문에, UX 전문가와 실사용자 그룹에서 얻은 데이터 전체를 활용하여 구조 방정식 모델 분석을 진행하였다. 그 결과 5장과 유사한 수준의 결과를 얻었고, 추후 해당 모델을 social AI personal assistant 제품에 일반화하여 활용할 수 있을 것으로 판단하였다. 본 논문은 social AI personal assistant 관련 제품 및 서비스의 개발 초기 단계에서 사용자 평가를 진행할 때 활용 가능한 평가 항목 및 평가 항목 간의 관계를 도출하였다. 또한 이를 검증하기 위하여 social AI personal assistant 제품 및 서비스를 활용한 사례연구를 진행하였다. 본 연구 결과는 추후 제품 개발 초기 단계에서 제품의 컨셉을 명확히 하기 위한 사용자 평가를 실시해야 하는 연구진이 효율적으로 활용할 수 있을 것으로 기대된다. 추후 이 부분의 검증을 위해, social AI personal assistants의 완제품과 개발 초기 단계의 video type stimulus를 비교하는 추가 연구가 이루어진다면 본 연구의 의미를 보다 명확하게 제시할 수 있을 것으로 생각된다.Chapter 1 Introduction 1 1.1 Background and motivation 1 1.1 Research objectives 5 1.2 Dissertation outline 7 Chapter 2 Literature review 9 2.1 Social AI personal assistant 9 2.2 User centered design process 13 2.3 Technology acceptance models 16 2.4 Evaluation measures for social AI personal assistant 22 2.5 Existing evaluation methodologies for social AI personal assistant 27 Chapter 3 Collection of existing evaluation measures for social AI personal assistants 40 3.1 Background 40 3.2 Methodology 43 3.3 Result 51 3.4 Discussion 60 Chapter 4 Development of an evaluation model for social AI personal assistants 63 4.1 Background 63 4.2 Methodology 66 4.2.1 Developing evaluation measures for social AI personal assistants 68 4.2.2 Conducting user evaluation for social robots 74 4.3 Result 77 4.3.1 Descriptive statistics 77 4.3.2 Hypothesis development and testing 80 4.3.3 Comparison with existing technology acceptance models 88 4.4 Discussion 93 Chapter 5 Verification of an evaluation model with voice assistant services 95 5.1 Background 95 5.2 Methodology 98 5.2.1 Design of evaluation questionnaires for voice assistant services 99 5.2.2 Validation of relationship among evaluation factors 103 5.3 Result 108 5.3.1 Descriptive statistics 108 5.3.2 Hypothesis development and testing 111 5.3.3 Comparison with existing technology acceptance models 118 5.4 Discussion 121 Chapter 6 Conclusion 124 6.1 Summary of this study 124 6.2 Contribution of this study 126 6.3 Limitation and future work 128 Bibliography 129 Appendix A.

Blurring the Line Between Human and Machine: Marketing Artificial Intelligence

One of the most prominent and potentially transformative trends in society today is machines becoming more human-like, driven by progress in artificial intelligence. How this trend will impact individuals, private and public organizations, and society as a whole is still unknown, and depends largely on how individual consumers choose to adopt and use these technologies. This dissertation focuses on understanding how consumers perceive, adopt, and use technologies that blur the line between human and machine, with two primary goals. First, I build on psychological and philosophical theories of mind perception, anthropomorphism, and dehumanization, and on management research into technology adoption, in order to develop a theoretical understanding of the forces that shape consumer adoption of these technologies. Second, I develop practical marketing interventions that can be used to influence patterns of adoption according to the desired outcome. This dissertation is organized as follows. Essay 1 develops a conceptual framework for understanding what AI is, what it can do, and what are some of the key antecedents and consequences of its’ adoption. The subsequent two Essays test various parts of this framework. Essay 2 explores consumers’ willingness to use algorithms to perform tasks normally done by humans, focusing specifically on how the nature of the task for which algorithms are used and the human-likeness of the algorithm itself impact consumers’ use of the algorithm. Essay 3 focuses on the use of social robots in consumption contexts, specifically addressing the role of robots’ physical and mental human-likeness in shaping consumers’ comfort with and perceived usefulness of such robots. Together, these three Essays offer an empirically supported conceptual structure ¬for marketing researchers and practitioners to understand artificial intelligence and influence the processes through which consumers perceive and adopt it. Artificial intelligence has the potential to create enormous value for consumers, firms, and society, but also poses many profound challenges and risks. A better understanding of how this transformative technology is perceived and used can potentially help to maximize its potential value and minimize its risks

A Review of Personality in Human Robot Interactions

Personality has been identified as a vital factor in understanding the quality of human robot interactions. Despite this the research in this area remains fragmented and lacks a coherent framework. This makes it difficult to understand what we know and identify what we do not. As a result our knowledge of personality in human robot interactions has not kept pace with the deployment of robots in organizations or in our broader society. To address this shortcoming, this paper reviews 83 articles and 84 separate studies to assess the current state of human robot personality research. This review: (1) highlights major thematic research areas, (2) identifies gaps in the literature, (3) derives and presents major conclusions from the literature and (4) offers guidance for future research.Comment: 70 pages, 2 figure
