Ehealth solutions are in great need in the community of elderly in general, as patients or home carers, however a design approach that delivers this is illusive. In this research we present the experiences from a set of design processes targeting elderly’s needs of support or home care, based on a co-design approach. The purpose is to present guiding principles for how to work with elderly in a co-design process, to be used as basis for future set up of co-design processes.
