A human-system integration framework and its application for special vehicle interface design under typical human...

Area of Science:

• Human System Integration (HSI)
• Human-Machine Interface (HMI) Design
• Systems Engineering

Background:

• Optimizing human system performance, cost-efficiency, and safety necessitates robust Human System Integration (HSI) practices throughout the system life cycle.
• Existing HSI practices are often limited within typical Human Readiness Levels (HRLs), posing challenges for effective integration.
• The development of specialized vehicles requires tailored HSI approaches to ensure seamless human-machine interaction.

Purpose of the Study:

• To propose a novel theoretical framework for Human System Integration (HSI) applicable across the life cycle.
• To apply and evaluate this HSI framework in the context of human-machine interface (HMI) design for special vehicles.
• To assess the effectiveness and identify areas for improvement in HSI practices within specific Human Readiness Levels (HRLs).

Main Methods:

• Development of a Human System Integration (HSI) theoretical framework based on the input-process-output model.
• Application of the HSI framework to a case study involving human-machine interface (HMI) design for special vehicles at HRLs 4-6.
• Conducting a stakeholder survey to evaluate the framework's effectiveness and the practical application of HSI processes.

Main Results:

• The proposed HSI framework effectively maps HSI processes and their support mechanisms across various Human Readiness Levels (HRLs).
• The case study identified critical HSI processes and their specific support needs for HMI design in special vehicles at HRLs 4-6, refining the framework.
• Stakeholder feedback validated the importance and effectiveness of the implemented HSI processes, highlighting opportunities for enhanced structuring and operability.

Conclusions:

• The developed HSI framework provides a structured approach to integrating human factors throughout the system life cycle, particularly for special vehicles.
• The study successfully merged theoretical HSI principles with practical case study insights, offering valuable guidance for HSI practices under typical HRLs.
• Improvements in the structuring and operability of HSI processes are recommended to further optimize human system performance and safety.
