Human-robot interactions with an autonomous health screening robot in long-term care settings

Socially assistive robots are increasingly being considered to help address the shortage of care workers in long-term care, which has been further exacerbated by the COVID-19 pandemic. In this paper, we present the first human-robot interaction study with care staff and an autonomous screening socially assistive robot in a long-term care facility. We assessed: (1) overall perceptions, experiences and attitudes of care staff prior to and after interacting with the robot, and (2) perceived workload and usability of the robot by administrators and management staff. Results show staff had overall high ratings of the robot, with a statistically significant increase identified for cognitive attitude towards the robot after interaction. Furthermore, we found that overall, perceived workload was moderately low as defined by the NASA Task Load Index while using the robot screener, and the usability rating of the robot was rated between OK and Good by the System Usability Scale. Personalization of the robot was found to be an important factor for usability. Staff enjoyed using the robot and had high willingness to frequently use it. In general, our robot study motivates the application of autonomous socially assistive robots from the staff perspective for repetitive tasks in long-term care homes.
