Abstract

A variety of healthcare robots for elderly care have been developed. However, as the elderly and caregivers experience psychological resistance towards not only new technologies but specifically to robots, the adoption of healthcare robots has scarcely progressed. This article aims to develop a service design method, which consists of a design process including design tools to identify jobs in an elderly care facility and to reveal what kinds of jobs to assign to service robots and to caregivers. This article develops a design method which is composed of six steps and adopts original design tools to identify jobs needed in elderly care facilities and assign them to human and non-human actors, including service robots. The tools include an actor map to visualize the Actor to Actor (A2A) network, a current jobs to be done (JTBD) worksheet to visualize existing jobs, a new JTBD worksheet to visualize new jobs, and an actor worksheet to summarize information about each actor including their philosophy. With this design method, we conducted a series of workshops with the aim to develop a service fulfilled by humans and non-humans at an elderly care facility in Shizuoka prefecture in Japan. The results of questionnaires administered to the workshop participants demonstrated the effectiveness of all the tools except the new JTBD worksheet. Also, the results of interviews with employees in the elderly care facility indicated the effectiveness of the approach, which reveals visible and invisible regulative, normative and cultural-cognitive elements through interviews with human actors, and embeds them in the service design process. The design method including the original design tools proposed in this article contribute to a service design method for the use of robots in elderly care facilities by allocating jobs to human actors and non-human actors appropriately, and it also contributes to the issue of psychological resistance to the adoption of service robots in these facilities, which brings efficiencies to society. The contribution of this article is to reframe the issue of resistance to the adoption of service robots in elderly care facilities to the issue of what kinds of jobs in an elderly care facility should be assigned to service robots or caregivers, and the development of a service design process including original design tools.
