Mitigating Children’s Pain and Anxiety during Blood Draw Using Social Robots

Young pediatric patients who undergo venipuncture or capillary blood sampling often experience high levels of pain and anxiety. This often results in distressed young patients and their parents, increased treatment times, and a higher workload for healthcare professionals. Social robots are a new and promising tool to mitigate children’s pain and anxiety. This study aims to purposefully design and test a social robot for mitigating stress and anxiety during blood draw of children. We first programmed a social robot based on the requirements expressed by experienced healthcare professionals during focus group sessions. Next, we designed a randomized controlled experiment in which the social robot was applied as a distraction method to measure its capacity to mitigate pain and anxiety in children during blood draw in a children’s hospital setting. Children who interacted with the robot showed significantly lower levels of anxiety before actual blood collection, compared to children who received regular medical treatment. Children in the middle classes of primary school (aged 6–9) seemed especially sensitive to the robot’s ability to mitigate pain and anxiety before blood draw. Children’s parents overall expressed strong positive attitudes toward the use and effectiveness of the social robot for mitigating pain and anxiety. The results of this study demonstrate that social robots can be considered a new and effective tool for lowering children’s anxiety prior to the distressing medical procedure of blood collection.

Social Robots for Elderly Care

Robots in education

The challenges facing primary education are significant: a growing teacher shortage, relatively high administrative burdens that contribute to work-related stress and an increasing diversity of children in the classroom. A promising new technology that can help teachers and children meet these challenges is the social robot. These physical robots often use artificial intelligence and can communicate with children by taking on social roles, such as that of a fellow classmate or teaching assistant. Previous research shows that the use of social robots can lead to better results in several ways than when traditional educational technologies are applied. However, social robots not only bring opportunities but also lead to new ethical questions. In my PhD research, I investigated the moral considerations of different stakeholders, such as parents and teachers, to create the first guideline for the responsible design and use of social robots for primary education. Various research methods were used for this study. First of all, a large, international literature study was carried out on the advantages and disadvantages of social robots, in which 256 studies were ultimately analysed. Focus group sessions were then held with stakeholders: a total of 118 parents of primary school children, representatives of the robotics industry, educational policymakers, government education advisors, teachers and primary school children contributed. Based on the insights from the literature review and the focus group sessions, a questionnaire was drawn up and distributed to all stakeholders. Based on 515 responses, we then classified stakeholder moral considerations. In the last study, based on in-depth interviews with teachers who used robots in their daily teaching and who supervised the child-robot interaction of >2500 unique children, we studied the influence of social robots on children's social-emotional development. Our research shows that social robots can have advantages and disadvantages for primary education. The diversity of disadvantages makes the responsible implementation of robots complex. However, overall, despite their concerns, all stakeholder groups viewed social robots as a potentially valuable tool. Many stakeholders are concerned about the possible negative effect of robots on children's social-emotional development. Our research shows that social robots currently do not seem to harm children's social-emotional development when used responsibly. However, some children seem to be more sensitive to excessive attachment to robots. Our research also shows that how people think about robots is influenced by several factors. For example, low-income stakeholders have a more sceptical attitude towards social robots in education. Other factors, such as age and level of education, were also strong predictors of the moral considerations of stakeholders. This research has resulted in a guideline for the responsible use of social robots as teaching assistants, which can be used by primary schools and robot builders. The guideline provides schools with tools, such as involving parents in advance and using robots to encourage human contact. School administrators are also given insight into possible reactions from parents and other parties involved. The guideline also offers guidelines for safeguarding privacy, such as data minimization and improving the technical infrastructure of schools and robots; which still often leaves much to be desired. In short, the findings from this thesis provide a solid stepping stone for schools, robot designers, programmers and engineers to develop and use social robots in education in a morally responsible manner. This research has thus paved the way for more research into robots as assistive technology in primary education.

Social Robots in the Wild and the Novelty Effect

We designed a wine recommendation robot and deployed it in a small supermarket. In a study aimed to evaluate our design we found that people with no intent to buy wine were interacting with the robot rather than the intended audience of wine-buying customers. Behavioural data, moreover, suggests a very different evaluation of the robot than the surveys that were completed. We also found that groups were interacting more with the robot than individuals, a finding that has been reported more often in the literature. All of these findings taken together suggest that a novelty effect may have been at play. It also suggests that field studies should take this effect more seriously. The main contribution of our work is in identifying and proposing a set of indicators and thresholds that can be used to identify that a novelty effect is present. We argue that it is important to focus more on measuring attitudes towards robots that may explain behaviour due to novelty effects. Our findings also suggest research should focus more on verifying whether real user needs are met.

Attitudes towards Social Robots in Education

While social robots bring new opportunities for education, they also come with moral challenges. Therefore, there is a need for moral guidelines for the responsible implementation of these robots. When developing such guidelines, it is important to include different stakeholder perspectives. Existing (qualitative) studies regarding these perspectives however mainly focus on single stakeholders. In this exploratory study, we examine and compare the attitudes of multiple stakeholders on the use of social robots in primary education, using a novel questionnaire that covers various aspects of moral issues mentioned in earlier studies. Furthermore, we also group the stakeholders based on similarities in attitudes and examine which socio-demographic characteristics influence these attitude types. Based on the results, we identify five distinct attitude profiles and show that the probability of belonging to a specific profile is affected by such characteristics as stakeholder type, age, education and income. Our results also indicate that social robots have the potential to be implemented in education in a morally responsible way that takes into account the attitudes of various stakeholders, although there are multiple moral issues that need to be addressed first. Finally, we present seven (practical) implications for a responsible application of social robots in education following from our results. These implications provide valuable insights into how social robots should be implemented

Robots are Good for Profit

From the pubisher's website: This paper aims to chart the (moral) values from a robotic industry's perspective regarding the introduction of robots in education. To our knowledge, no studies thus far have addressed this perspective in considering the moral values within this robotic domain. However, their values could conflict with the values upheld by other relevant stakeholders, such as the values of teachers, parents or children. Hence, it is crucial to take the various perspectives of relevant stakeholder's moral values into account. For this study, multiple focus group sessions (n=3) were conducted in The Netherlands with representatives (n=13) of robotic companies on their views of robots in primary education. Their perceptions in terms of opportunities and concerns, were then linked to business values reported in the extant literature. Results show that out of 26 business values, mainly six business values appeared relevant for robot tutors: 1) profitability, 2) productivity, 3 & 4) innovation and creativity, 5) competitiveness, and 6) risk orientation organization. https://doi.org/10.1109/DEVLRN.2019.8850726
