  This paper describes some of the challenges set within SPHERE, a large-scale
Interdisciplinary Research Collaboration that aims to develop sensor systems to
monitor people's health and wellbeing in the home. In particular we discuss the
dual task facing the User- Centered Design research group, to ensure the
development of inclusive and desirable domestic healthcare technology. On the
one hand, we seek to gain a rich understanding of the many envisaged users of
the SPHERE system. On the other hand, for the user experience requirements to
be translated into tangible outputs, it is crucial that we effectively
communicate these findings to the broader team of SPHERE engineers and computer
scientists.
