Grand Challenges around Designing Computers’ Control Over Our Bodies

Publication Info

• Topic area: Human-computer interaction with a focus on bodily control technologies.
• Keywords: bodily control, human-computer interaction, electrical muscle stimulation, shared agency, ethics, wearability, actuation, embodied interaction, user evaluation, cultural sensitivity.

Background and Problem

• Problem / challenge: The field lacks a unified understanding and structured research agenda for designing systems where computers take control over human bodies. Existing work is fragmented across technical, experiential, and ethical dimensions, leaving gaps in addressing safety, agency, inclusivity, and usability.
• Significance: As bodily control systems become more prevalent in healthcare, rehabilitation, entertainment, and other domains, addressing these challenges is critical to ensure their safety, usability, and ethical deployment.
• Motivation and related work: Prior research has explored technologies like electrical muscle stimulation (EMS), exoskeletons, and haptic systems, but these studies often focus on isolated aspects such as usability or technical feasibility. Broader issues like shared control, agency, and cultural inclusivity remain underexplored, motivating the need for a comprehensive framework.

Solution

• Proposed approach: A set of grand challenges for designing computers’ control over human bodies, derived from a week-long workshop with 24 international experts.
• Novelty:
  1. Identification of grand challenges across four themes: technology, design, ethics, and users.
  2. Introduction of three complementary perspectives on bodily control: interaction-oriented, goal-oriented, and embodied-experiential.
  3. Articulation of motivations for yielding bodily control, such as gaining new abilities, reducing effort, and enhancing entertainment.
  4. Emphasis on ethical considerations, including inclusivity, cultural sensitivity, and the right to object.
• Procedure and key techniques:
  • Conducted a 5-day workshop with diverse experts to identify and refine challenges.
  • Used iterative clustering and discussion methods to synthesize 118 initial challenges into 10 grand challenges.
  • Incorporated perspectives from related fields like activity theory, embodied cognition, and interaction design.

Results

• Concrete findings:
  • Grand challenges include improving actuator wearability, developing automatic calibration methods, designing shared agency, ensuring safety, and creating inclusive evaluation frameworks.
  • Identified four dimensions of control: agency, directness, initiation, and transparency.
  • Highlighted motivations for yielding control, such as gaining superhuman abilities, reducing workload, and supporting rehabilitation.
• Advantage over baselines: The paper provides a structured and holistic framework that integrates technical, experiential, and ethical considerations, addressing gaps in prior fragmented research.
• Experiments / evaluation:
  • Workshop participants included experts from diverse fields (e.g., wearable computing, ethics, interaction design).
  • Challenges were derived through collaborative discussions, clustering, and iterative refinement.
• Limitations and future work:
  • Limited participant diversity due to logistical constraints.
  • Potential bias in workshop participant selection and consensus-driven discussions.
  • Future work should validate the effectiveness of the proposed challenges and include more diverse perspectives, such as those from physiotherapy, arts, and policy-making.

Summary

This paper identifies grand challenges for designing systems that allow computers to control human bodies, addressing critical gaps in technology, design, ethics, and user evaluation. Key contributions include a structured framework of challenges, three perspectives on bodily control, and motivations for yielding control. The findings emphasize the need for interdisciplinary collaboration to ensure these systems are safe, inclusive, and ethically responsible. This work provides a foundation for advancing research and fostering a more humane integration of bodily control technologies.
