[Emotional robots in a nursing context : Empirical analysis of the present use and the effects of Paro and Pleo].

BACKGROUND: It has been questioned by researchers in robotics as well in the general public to what extent companion-type robots can support the elderly with the fulfillment of their psychological and social needs. Although these robots have already been used in care settings in Germany, research has referred little to this practical experience in order to analyze their impact and benefit. To start to close this gap, the current article reports on the current use of companion-type robots in care settings, on the effects reported by professional caregivers as well as on the role of psychosocial needs in the acceptance and use of companion-type robots by the elderly.
MATERIAL AND METHODS: In the first study, 30 professional caregivers with experience in the use of the robot seal Paro in care settings were interviewed regarding Paro's application and the observed effects on their clients. In the second study, three case examples are presented from an interaction study in which vulnerable elderly persons had the robot dinosaur Pleo at their disposal for a maximum period of 15 days.
RESULTS: Paro is used very flexibly in a variety of settings and with a broad range of user groups (study 1). The reported psychosocial effects were mainly positive but short term. The case examples (study 2) show that psychosocial needs can both foster or hinder robot acceptance and use. They also emphasize the important role of caregivers in the interaction between the elderly and emotional robots in the context of eldercare.
CONCLUSION: The beneficial and ethical use of companion-type robots in care settings demands a high commitment on the part of the caregivers. Given this prerequisite, emotional robots can be a valuable therapeutic tool.
