Introduction to the special issue on technical and social advances in HRI

One of the goals of the Journal of Human-Robot Interaction (JHRI) is to promote a stronger research community, including interactions among HRI-relevant conferences and journals. This issue is comprised of papers that first appeared in another format, usually a conference, and that exhibited special insights or area of interest. Authors were invited to submit extensions to these papers with at least 50% new material and told that the papers would be reviewed relative to the standard of scholarship suited to an archival journal. Submitted papers were then reviewed by at least three reviewers, who were instructed to hold the papers to a journal-level standard for scholarship. Of the papers that were invited, five papers were selected for publication.
