In this paper, we investigate the use of ambient technology to create a classroom presence for hospitalised children. We present results from four case studies, each of which included data from hospitalised children, their parents, classmates and teachers (at both school and hospital). Primary school-aged children from both metropolitan and rural areas were included. Data collected at both the hospital and the classroom were analysed to investigate children's experience of the ambient technology and their desire to be aware of the presence of their peers, from both ends of the hospital-school setting. The results indicate that ambient technology is positive at fostering a mutual sense of presence, from the perspective of the hospitalised children, their family, teachers and classmates.
