This doctoral research project is now completed. I defended my PhD successfully in August 2021, after submitting the draft thesis for examination in early November 2020. I have published and continue to publish numerous papers about the research itself and about other aspects that arise out of the research. I have also presented for the past three years at the Human Computer Interaction International conference, in the Distributed, Ambient and Pervasive Interactions track, chaired by Dr H. Patricia McKenna. My Orcid is https://orcid.org/0000-0002-1071-693X.
