Research Background and Problem Statement

• Identified Issues:

  • With the development of wearable robotics, digital cyborgs have become a research hotspot. However, dimensions such as social interaction, communication, and aesthetics remain underexplored.
  • Previous studies on supernumerary robotic limbs (SRLs) have primarily focused on direct interaction between humans and devices, with limited attention to social interactions between cyborgs.
  • There is a lack of design principles and implementation methods related to cyborg societies.

• Significance:

  • Humans are inherently social beings, and artificial additional limbs may influence an individual's mode of social communication.
  • Understanding the social interaction patterns of digital cyborgs can help predict future "cyborg societies."

• Research Motivation and Related Work:

  • While there has been extensive attention on the development of SRLs, their social applications have been less discussed.
  • Imaginative scenarios inspired by literary works (e.g., Yasunari Kawabata's One Arm) provide inspiration for social interactions involving detachable and exchangeable limbs.

Proposed Solution

• Proposed Solution:

  • Developed a modular supernumerary robotic limb system named "JIZAI ARMS." This system consists of a wearable base and up to six detachable robotic arms, allowing users to freely attach, remove, and exchange these arms.

• Innovative Aspects:

  • Explored social interaction models of digital cyborgs, emphasizing the aesthetic experience of human-robot integration.
  • Focused on the shareability and interaction design of cyborg limbs, aiming to create a harmonious, aesthetically pleasing, and user-centric digital cyborg system.

• Implementation Steps:

  1. Literature Review: Conducted a comprehensive review of existing research related to JIZAI ARMS to identify research opportunities.
  2. Concept Development: Defined design goals and interaction scenarios through interdisciplinary collaboration.
  3. Design and Development: Designed and built a prototype system, emphasizing the integration of hardware and software.
  4. Role-Playing: Simulated various interaction scenarios by wearing the robotic arms to collect subjective experience data.
  5. Social Discussion: Derived models of interpersonal interaction in cyborg societies based on experimental experiences.

Research Outcomes

• Specific Achievements:

  • Successfully realized rapid detachment and sharing of robotic limbs based on modular design.
  • Provided detailed design documentation, including physical prototypes and interaction design.
  • Proposed new research directions for social interaction in digital cyborg societies.

• Advantages Compared to Existing Solutions:

  • Unlike existing mechanical and function-oriented designs, JIZAI ARMS emphasizes aesthetics and social interaction.
  • Enriched discussions on "body ownership" and "social ownership," offering valuable references for future designs.

• Experiments and Evaluation:

  • Collected firsthand data on wearing experiences, feelings of limb attachment and detachment, and social interactions through autobiographical records and role-playing experiments.
  • Identified changes in physical balance and psychological perceptions caused by the addition and removal of limbs.

• Limitations and Future Directions:

  • Limitations:
    • Data on wearing experiences primarily came from within the research team, resulting in a small sample size.
    • Did not include long-term studies on how limbs perform in more complex social scenarios.
  • Future Directions:
    • Explore personalization (e.g., through customized feedback and appearance) to enhance users' sense of belonging.
    • Study long-term social interactions among multiple cyborgs and the recognition of shared limb ownership.
    • Develop cyborg limbs that can further integrate into everyday applications.
