This paper reports on observations and discussions conducted through a weekly technology support service at a residential care facility for senior citizens. The intention with the fieldwork was to get a better understanding of the knowledge and relations seniors, living in smart homes, have with modern digital technologies. The findings are presented in the form of two vignettes and analysed through the lens of actor-network theory. The analysis shows how the use of technology is immersed in a web of socio-technical relations. It also shows that these relations contribute to dynamically enable or disable actors in a variety of ways. The contribution of this work is to give some reflections on how socio-technical structures affect the character of ability and disability, and the implications this has for the design of welfare technology.
