The HMI systems are a type of user interface (UI) that are widely used in the industrial design field. As the name suggest they are used for computer-human-interaction. These systems basically receives imput from the human in the form of signals and commands processes them and sends to the machine in order to get a desired result. This interaction allows effective operation and control of the machine from the human end. The HMI systems also feeds back information that aids the operators' decision-making process. Further, they are used in industrial processes, robotics like auto paint shop and CNC design.
