Technology can be very valuable to support older adults to remain healthy and active in their daily living. How to design technological product and service systems that will be adopted by older adults however still remains a challenge. This paper reports on an empirical study on how a co-creation ideation process can contribute to the technology adoption of older adults conducted in an EU project with multi-stakeholder teams with the aim of promoting physical activities of older adult citizens. This ideation process is adapted from Method A. By analyzing the co-creation ideation process from three different processes: the end user value-creation process, the stakeholder value-creation process and the encounter process in relation to the technology adoption process, i.e., the domestication adoption process, this paper demonstrates which technology adoption issues can be already addressed using this cocreation ideation process and which aspects still need to be taken further into account.
