Paper Information

• Research Area: Human-Computer Interaction (HCI), Assistive Technology for Older Adults, Participatory Design
• Keywords: Human-Computer Interaction, Older Adults, Assistive Robots, Accessible Design, Design Methods, Participatory Design, Field Studies

Research Background and Issues

• Identified Problems or Challenges:
  1. Low acceptance of assistive robots among older adults.
  2. Limited involvement of older adults in current technology design processes, leading to insufficient understanding of their needs.
  3. Four major challenges in conventional participatory design:
     • Cognitive Abilities: Some older adults struggle to clearly articulate their needs or engage in creative thinking.
     • Physical Abilities: Physical limitations or difficulty accessing research sites exclude certain older adults from participation.
     • Complex Environments: The living environments of older adults are often complex, involving spatial modifications, fixed daily routines, and cohabitation with family or caregivers.
     • Needs of Other Stakeholders: The needs of caregivers and family members are often overlooked.
• Research Significance:
  • Understanding how older adults interact with technology in daily life can improve acceptance and adoption rates.
  • Assistive technology for older adults must consider real-world environmental constraints and needs from the design phase.
• Research Motivation:
  • Current participatory design methods, while accessible, are limited in capturing the true needs of older adults regarding robotic technology.
  • Direct interaction with technology can provide more authentic user feedback and validate design assumptions.

Proposed Solution

• Proposed Method: The authors propose a method called "Situated Participatory Design (sPD)." This method integrates user-centered design and participatory design, focusing on immersive design processes within real-world environments.
• Innovative Aspects:
  • Full simulation of technology usage scenarios.
  • Conducting participatory design activities in actual usage environments.
  • Incorporating phased validation, authentic interaction experiences, and multi-stakeholder involvement.
• Implementation Steps:
  1. Phase 1: Discovery, Co-Design, and Scenario Rehearsal
     Explore technological capabilities, design interaction scenarios, and conduct initial design through robot user rehearsals (Wizard-of-Oz).
  2. Phase 2: Simulated Deployment
     Validate the design multiple times in real environments, minimizing researcher intervention, and observe direct interaction between the robot and users.
  3. Phase 3: Stakeholder Feedback
     Invite other stakeholders (e.g., caregivers) to reflect on the scenarios and provide suggestions on broader design issues.

Specific technical methods include using real robotic platforms, in-situ user rehearsals, Wizard-of-Oz simulated deployments, and stakeholder interviews.

Research Findings

• Specific Outcomes:
  1. Most older adult participants were satisfied with the tasks performed by the robot and provided suggestions for improvements, such as water delivery and parcel services.
  2. The study found that iterative, multi-phase, in-situ interactions enhanced design precision and helped users better understand how robots could integrate into their daily lives.
  3. Feedback from caregivers highlighted ethical issues in real-world applications, such as privacy and safety.
• Advantages:
  1. Increased depth and accuracy of older adults' participation.
  2. Ability to capture issues within complex ecosystems, such as the impact of unplanned events on the robot.
  3. Progressive refinement of design ideas through multi-phase testing to meet more practical needs.
• Experimental Results:
  • Phased simulated deployments revealed evolving user needs regarding task prioritization and interaction modes (e.g., robot voice prompts).
  • Participation from different stakeholders (residents and caregivers) underscored the necessity of validating the rationality of robot behaviors.
• Limitations:
  1. High initial resource investment required for implementation, making scalability challenging.
  2. Testing was limited to a single type of robot, without comparisons across different technological platforms.
  3. The sample size was small, excluding older adults with severe cognitive impairments.
• Future Directions:
  1. Apply sPD to other vulnerable groups, such as children or individuals with visual impairments.
  2. Explore scalability through additional design iterations and automation technologies.
  3. Increase participation from a broader range of stakeholders, such as family members, to better understand and balance diverse needs.
