While many health-care issues and technological solutions are viewed locally, developing new technological solutions might benefit from lessons learned globally. The aim of this study was to develop a shared international research agenda of health-care ICT, applied to rehabilitation and daily living support. This study was focused on sensor technology and social robots used for supporting older persons in the Netherlands (Amsterdam) and Japan (Tokyo). Three researchers from Amsterdam University of Applied Sciences visited Japan and four researchers from Tokyo Metropolitan University visited the Netherlands and conducted field-visits and mutual presentations. Using a nominal group technique (NGT) facilitated the expert panel deliberations. Research priorities were identified qualitatively through in-action critical reflection on emerging ideas, and quantitatively by ranking of identified knowledge gaps (using the Mentimeter© app). The resulting joint research agenda identified topics around the utility of sensor monitoring and processes of acceptance of health-care ICT among older persons and occupational therapists. The agenda was complemented by formulating underlying assumptions prescribing such research to be embedded in real-life situations with the participation of stakeholders.
