The needs assessments provided a list of potential features, behaviours, and functionality for the social robot in the target setting. To implement the robot system, it was necessary to translate those needs and features into concrete technical requirements for the developers of the robot system. To accomplish this, the project’s technical team met with an additional group of HCPs to jointly develop a flowchart indicating the robot’s role at each stage of the IVI process, and to translate the focus group results into concrete technical requirement for the robot at each stage of the interaction. Dr. Foster will describe how the HCPs and the technical team turned the identified needs into concrete technical design constraints, using concrete examples from all stages of the designed human-robot interaction flowchart. She will then outline how the system was developed following those technical constraints, showing how the constraints influenced the system design throughout the process. The system has been designed not only to meet the interaction constraints from the flowchart, but also to behave robustly and predictably in the target environment, with the goal of enhancing the HCP’s work without interfering with the primary task being carried out in the ED.
