ISA-TR101.02 : 2019

ISA-TR101.02-2019, HMI Usability and Performance, covers the entire human machine interface (HMI) from system standards and design through implementation, operation, maintenance and continuous improvement. It focuses on optimizing operator interaction, situational awareness and effective responses to abnormal conditions. This report emphasizes human factors engineering (HFE), consistent design practices, appropriate use of color and graphics, navigation and testing methods to enhance usability and performance.ISA-TR101.02 also includes recommended performance metrics for different HMI categories, assessment criteria for HMI effectiveness and a case study that demonstrates significant improvements using High Performance HMI principles.
