Application of human-centered design principles to wearable exoskeletons: a systematic review

Abstract

Purpose of the article: As technologies continue to advance, designing wearable exoskeletons that are comfortable, safe, reliable, and engaging for users is an arduous task. The integration of HCD principles in exoskeleton development significantly contributes to ensuring that the product meets the needs and preferences of users. This study systematically reviews the application of human-centred design (HCD) principles in the development of wearable exoskeletons. Methodology: It synthesizes existing literature, identifies key HCD concepts and assesses their impact on exoskeleton usability, comfort, and safety. The findings of the study revealed a moderate application of HCD in many of the studies; however, the concepts were found to play a crucial role in enhancing the usability, safety, and comfort of wearable exoskeleton technology implementation. Challenges revealed in the study include limited stakeholder involvement, a lack of standardized evaluation metrics, non-consideration of ethical, legal, and social issues, and a lack of studies on the potential adverse effects of exoskeleton use. Besides identifying the challenges faced in integrating HCD principles into exoskeleton development, the study also proposed pragmatic approaches to overcome them. Results: The study underscores the significance of incorporating human-centred design principles in the design and development of wearable exoskeletons. This has implications for industry, rehabilitation, health, and agriculture to churn out positive outcomes. The research contributes to the expanding literature on wearable exoskeletons and HCD, offering valuable insights into the advancement of this technology in various domains and suggesting areas for future studies to address identified gaps.
