Human-Centered Infrastructure: Re-evaluating HCI in the Context of Modern Sociotechnical Systems

Abstract

This research report critically examines the evolving landscape of Human-Centered Infrastructure (HCI), moving beyond its conventional understanding as solely Hyper-Converged Infrastructure within IT. We argue for a broader interpretation of HCI that encompasses the design, implementation, and management of sociotechnical systems with a primary focus on human needs, capabilities, and limitations. This perspective incorporates technical infrastructure, organizational structures, and human factors to optimize system performance, usability, and societal impact. The report explores the limitations of solely focusing on technological efficiency metrics, such as those prioritized in traditional Hyper-Converged Infrastructure deployments, and advocates for a more holistic approach that considers the human element as an integral component of the overall infrastructure. We investigate the theoretical foundations of this expanded HCI concept, analyze its application across diverse domains, and discuss the challenges and opportunities associated with its adoption. Finally, the report proposes future research directions for advancing the field of Human-Centered Infrastructure and ensuring that technology serves humanity effectively and ethically.

1. Introduction: Beyond Hyper-Convergence

The acronym ‘HCI’ is frequently associated with Hyper-Converged Infrastructure, a popular IT architecture integrating compute, storage, and networking into a unified system. While the efficiencies and scalability offered by Hyper-Converged Infrastructure are undeniable, this report posits that ‘HCI’ warrants a significantly broader interpretation: Human-Centered Infrastructure. This expanded definition moves beyond the technical specifications of data centers and embraces a sociotechnical perspective, where infrastructure encompasses the interconnected elements—technical, social, and organizational—that support human activity. We argue that focusing solely on the technological aspect of HCI risks overlooking the crucial human element, leading to suboptimal system design and potential negative consequences.

This broadened understanding of HCI is not merely a semantic shift. It reflects a fundamental change in perspective, prioritizing human needs, capabilities, and limitations as central design considerations. This entails a shift from technology-driven development to a human-centered approach, where technology serves as a tool to enhance human well-being and productivity. This research report will explore the theoretical foundations of Human-Centered Infrastructure, examine its application across diverse domains, and discuss the challenges and opportunities associated with its adoption. The aim is to provide a comprehensive framework for understanding and implementing HCI in a way that maximizes its positive impact on individuals and society.

The shift towards a human-centered approach is driven by several key factors:

• Increasing System Complexity: Modern systems are becoming increasingly complex, involving intricate interactions between humans, technology, and organizations. A solely technology-focused approach often fails to adequately address the challenges posed by this complexity.
• Ethical Considerations: The widespread deployment of technology raises profound ethical questions about its impact on privacy, autonomy, and social justice. Human-Centered Infrastructure provides a framework for addressing these ethical concerns by prioritizing human values in the design and implementation of technology.
• Improved System Performance: By considering human factors, organizations can design systems that are more efficient, usable, and resilient. This can lead to significant improvements in productivity, safety, and overall system performance.
• Enhanced User Experience: A human-centered approach ensures that systems are designed with the user in mind, leading to a more positive and satisfying user experience. This can increase adoption rates and reduce training costs.

2. Theoretical Foundations of Human-Centered Infrastructure

Human-Centered Infrastructure draws upon a diverse range of theoretical frameworks, including:

• Human-Computer Interaction (HCI): The traditional field of HCI focuses on the design of user interfaces and the interaction between humans and computers. While HCI primarily addresses the micro-level interaction, Human-Centered Infrastructure extends this perspective to encompass the entire sociotechnical system.
• Sociotechnical Systems Theory: Sociotechnical systems theory emphasizes the interdependence between social and technical elements within an organization. It recognizes that system performance is determined by the interplay between these elements and that optimizing one element in isolation can lead to unintended consequences.
• Usability Engineering: Usability engineering focuses on designing systems that are easy to use, learn, and remember. Human-Centered Infrastructure incorporates usability principles to ensure that systems are accessible and effective for all users.
• Cognitive Systems Engineering (CSE): CSE addresses the challenges of designing complex systems that support human cognition and decision-making. It emphasizes the importance of understanding how humans perceive, process, and act upon information in complex environments.
• Resilience Engineering: Resilience engineering focuses on designing systems that can adapt and recover from unexpected events. Human-Centered Infrastructure incorporates resilience principles to ensure that systems are robust and can withstand disruptions.
• Actor-Network Theory (ANT): ANT provides a framework for understanding how diverse actors, both human and non-human (including technologies, policies, and resources), interact and shape the development and evolution of sociotechnical systems. It helps analyze the complex relationships and power dynamics within an infrastructure.

These theoretical frameworks provide a foundation for understanding the complex interactions between humans, technology, and organizations within Human-Centered Infrastructure. They emphasize the importance of considering human factors, social context, and organizational structures in the design and implementation of infrastructure systems.
