Human-Computer Interaction - Special Issue on Human-Robot Interaction -- "We invite significant research papers that examine human-robot interaction and its social context. Preference will be given to systematic empirical studies or analyses over essays or descriptions of technology development. "Empirical" for this purpose will be defined broadly and could include experiments, usability studies, ethnographies, archival data analysis, surveys, and so forth. We encourage papers that represent a variety of disciplinary perspectives and analytical approaches."
