The Mitsubishi 10-inch Human Machine Interface (HMI) model A970GOT-TBD-B, belonging to the A975GOT series, is a high-performance industrial touchscreen interface designed for seamless interaction between operators and automated machinery or processes. This HMI features a 10-inch high-brightness TFT color display with a resolution of 600 × 480 pixels, capable of rendering 16 distinct colors. It operates on a DC 24V power supply and comes equipped with a 1 MB memory card for data storage and application functionality.

The concept of a human-machine interface refers to the domain or surface where information exchange, functional contact, or mutual influence occurs between humans and machines. This interface encompasses both physical and non-physical interactions, including direct contact at points, lines, or surfaces, as well as remote information transfer and control actions across space. As a central component of any human-machine system, the HMI serves as the critical link that translates internal system data into forms that humans can perceive, understand, and act upon.

The study and optimization of this interface fall under the field of safety ergonomics, a sub-discipline of safety engineering. Safety ergonomics provides the theoretical basis for designing interfaces that reduce human error, enhance operational efficiency, and ensure user safety. Practical solutions, methods, and measures are developed through related disciplines such as safety equipment engineering, safety management engineering, and safety system engineering. Together, these fields address the physical, cognitive, and environmental aspects of the human-machine interface, ensuring that information is effectively converted from internal machine formats into user-friendly representations.
