HMI, or Human-Machine Interface, refers to the technology that allows humans to interact with machines and devices in a user-friendly and intuitive manner. It serves as a bridge between the user and the machine, enabling the exchange of information and commands through visual, auditory, and tactile means. HMI plays a crucial role in enhancing the usability and efficiency of various systems, from simple household appliances to complex industrial machinery. With the advancement of technology, HMI has evolved to include touchscreens, voice recognition, and gesture control, making the interaction between humans and machines more seamless and natural.
