Care Workers Making Use of Robots: Results of a Three-Month Study on Human-Robot Interaction within a Care Home

Paper Information

• Research Area: Human-Robot Interaction, Application of Social Robots in Care Work
• Keywords: Human-Robot Interaction, Social Robots, Long-Term Study, Care Work, Participatory Design, Robot-Assisted Practices, Routine Use, Pandemic Impact (COVID-19), Sustainable Technology Integration

Research Background and Issues

• Problems or Challenges:
  • Social robot technology has not yet been widely integrated into care work.
  • The care industry faces resource constraints and labor shortages.
  • Existing studies often focus on the user experience of care recipients (residents) or technical testing, but there is a lack of research on how care workers integrate robots into their daily work over the long term. Moreover, the actual effectiveness of robots in alleviating care work burdens remains unclear.
• Significance:
  • An aging society and labor shortages compel the search for new technological solutions to support the care industry. Particularly during the COVID-19 pandemic, robots may help limit virus transmission by reducing interpersonal contact.
• Research Motivation and Related Work:
  • Although studies have explored the application of care robots in elderly care and dementia care, these applications are mostly limited to short-term experiments or emotional aspects of patients.
  • Under the direction of long-term research and practice-based studies, issues such as the participation of care workers, actual workflows involving robots, and barriers to adapting to robotic technology have been overlooked.

Solution

• Proposed Method or Solution:
  • Conduct a three-month field study in a care institution housing 49 residents, utilizing the "Pepper" robot to observe how care workers apply, interact with, and adapt to the technology in their daily work.
• Innovative Features:
  • Introduce robots into daily care work and allow care workers to freely explore usage methods rather than predefining specific usage patterns.
  • Incorporate participatory design principles to develop new robot applications based on the needs of care workers.
  • Conduct in-depth qualitative research on the technological adaptation process of care workers, supplemented by quantitative analysis through various data collection methods such as participant observation, interviews, and logs.
• Implementation Steps and Key Technologies:
  1. Pre-study: Conduct preliminary interviews and on-site observations to understand the actual needs of care work.
  2. Deployment and Observation:
     • Deploy the robot within the care institution for three months and provide care workers with a remote control mobile app and user manual.
     • Robot applications include three categories: motor skills, cognitive stimulation, and psychosocial support, with usage logs recording daily robot activities.
     • Conduct regular on-site visits for observation, supplemented by group discussions to evaluate adaptation progress.
  3. Participatory Design: Develop new applications based on care workers' needs, such as singing, quiz games, and age-guessing interactive modules.

Research Outcomes

• Specific Results:
  • Care workers used the robot for an average of 1 hour and 7 minutes daily, covering one-on-one interactions and group activities.
  • Newly developed applications (e.g., Christmas songs, football-themed music) were the most popular, enhancing residents' engagement and mood.
  • Although the robot did not significantly alleviate care workers' workload, it notably improved the quality of care services by stimulating social and recreational activities.
• Advantages Compared to Existing Solutions:
  • Long-term observations indicate that robots have potential in reducing residents' feelings of loneliness and enhancing interactions.
  • Deep integration with care work has promoted mutual progress in care practices and technology.
• Experimental or Evaluation Results:
  • Psychosocial activation applications, including music interactions and cognitive quizzes, accounted for 67% of usage time during scheduled activities.
  • Care workers' acceptance of the robot depended on individual initiative and cognitive adaptability, with some workers gradually becoming "core users" who trained other staff.
• Limitations and Future Directions:
  • Research conditions were limited due to the pandemic, with robot usage significantly declining during the Christmas period.
  • Technical issues (e.g., limited mobility of the robot, insufficient fault transparency) increased care workers' psychological burden.
  • The study was restricted to a single care institution with a small sample size. Future research should expand the sample across multiple regions and cultural contexts.
  • Explore how technological upgrades (e.g., improved robot mobility, enhanced sensor sensitivity) and long-term implementation strategies can reduce psychological and physical burdens.

Summary and Reflection

• Key Findings:
  • Robots need to be actively integrated into care workflows to achieve true human-robot hybrid work.
  • Participatory design is essential to ensure robotic technology meets actual needs and achieves deep localized deployment.
• Recommendations:
  • Provide continuous training for care workers to improve technological adaptability.
  • Optimize robot usage strategies through planned activities and long-term feedback.
  • Robots should not be expected to reduce manpower but should be viewed as a means to enhance care quality.

Research Significance: By comprehensively studying how care robots impact the work practices of social care workers, this research reveals the current state of robotic technology integration into care work and provides guidance for more efficient and targeted robot development and research in the future.
