Document Information

• Subject Area: Human-Computer Interaction (HCI), Haptic Technology, Responsible Innovation
• Keywords: Touch-based interaction, airborne haptic feedback, ethics, responsible innovation, social interaction, ultrasonic technology, emotional haptics, user experience design, multisensory integration, social impact

Research Background and Issues

• Identified Problems or Challenges: The development of touch-based technology has driven innovation in various interaction methods, such as airborne haptic feedback enabled by ultrasonic waves. However, the ethical and social implications of these touch-based systems in diverse application scenarios of social interaction have not been thoroughly explored. Additionally, future applications of touch-based technology may bring complex ethical issues and societal challenges, such as privacy, security, and technology acceptance.
• Importance: In the post-pandemic era, these technologies not only facilitate human interaction but also provide non-contact solutions for fields like healthcare and education. However, the lack of in-depth discussions on their ethical and social responsibilities may lead to misuse or negative impacts of the technology.
• Research Motivation and Related Work: While previous studies have explored the technical possibilities of ultrasonic technology and airborne haptics, insights into their future development and ethical implications are still lacking. This study is motivated by the need to reflect on and design future touch-based technologies through the lens of the responsible innovation framework, thereby addressing this research gap.

Solution

• Proposed Solution: The authors conducted design exploration workshops with 20 experts in the field of haptic technology, adopting roles as Dreamers, Realists, and Critics to brainstorm and generate 48 ideas for future social interaction scenarios involving touch-based applications. These ideas were then evaluated for ethical and social impacts using thematic analysis within the responsible innovation framework.

• Innovations:

  • Applying the responsible innovation framework (including anticipation, reflection, inclusion, and responsiveness) to scrutinize future touch-based technologies.
  • Collaborating with experts from academia and industry to conduct practice-driven design explorations for future applications.

• Implementation Steps and Key Techniques:

  1. Workshop Design: Two online workshops focused on generating innovative ideas and critically evaluating them.
     • First workshop: Focused on imagining future application scenarios (roles of Dreamers and Realists).
     • Second workshop: Examined and refined project design concepts (roles of Realists and Critics).
  2. Concept Extraction and Analysis: Extracted key factors from the 48 ideas, including technological objectives, social benefits, novelty, challenges, ethical responsibilities, target users/scenarios, etc.
  3. Responsible Innovation Framework Evaluation: Assessed the potential impacts of the innovative ideas using RI principles (anticipation, reflection, etc.).

Research Outcomes

• Specific Outcomes:

  • Cross-Idea Concepts: Identified five core concepts for future touch-based technology applications: sensory interaction, emotional triggers, entertainment, remote interaction, and stored interaction.
  • Social Benefits: Experts suggested that the technology could enhance social connections, improve well-being (e.g., healthcare applications), and facilitate communication. Application scenarios include hospitals, homes, education, and entertainment.
  • Ethical Responsibilities: Key ethical considerations identified through the responsible innovation framework include safety (awareness of risks related to ultrasonic exposure), acceptability (cultural differences affecting acceptance), and privacy (avoiding intrusive tactile experiences).

• Advantages:

  • Compared to traditional haptic technologies, airborne haptics offer more flexible, non-contact interaction forms, providing safer options for post-pandemic social interaction.
  • By focusing on user experience and ethical responsibilities, the technological solutions emphasize not only functional innovation but also social and cultural values.

• Experimental or Evaluation Results:

  • Experts rated the ideas based on expectations and feasibility through discussions and voting. Results showed that future applications aimed at enhancing well-being (e.g., emotional assistance) were more favored, while entertainment-related ideas had lower acceptance.
  • No actual implementation projects were conducted; the evaluation was primarily based on potential conceptual designs.

• Limitations and Future Directions:

  • Limitations:
    • Workshops lacked participants with social science and philosophical backgrounds.
    • Gender imbalance among experts, with male participants dominating.
    • Analysis was predominantly based on technical perspectives of experts, with insufficient evaluation of user diversity (e.g., cultural, economic backgrounds).
  • Future Directions:
    • Invite experts from broader backgrounds, including sociology and philosophy.
    • Further explore ethical frameworks and regulations for digital haptics (e.g., moral licensing issues in virtual dating and interactions).
    • Conduct practical explorations of certain proposed application scenarios.

Conclusion

This study combines design exploration with the responsible innovation framework to analyze the potential applications and ethical issues of future touch-based technologies in social interaction scenarios. The authors propose novel design concepts and reveal the balance between technological, ethical, and social values, providing critical guidance for the future development of touch-based technologies.
