A Human-Machine Interface (HMI) is a user interface or dashboard that connects a person to a machine, system, or device. While the term can technically be applied to any screen that allows a user to interact with a device, HMI is most commonly used in the context of an industrial process.
Similar to how you would interact with your air-conditioning system to check and control the temperature in your house, a plant-floor operator might use an HMI to check and control the temperature of an industrial water tank, or to see if a certain pump in the facility is currently running.
HMIs come in a variety of forms, from built-in screens on machines, to computer monitors, to tablets, but regardless of their format or which term you use to refer to them, their purpose is to provide insight into mechanical performance and progress.

The most common roles that interact with HMIs are operators, system integrators, and engineers, particularly control system engineers. HMIs are essential resources for these professionals, who use them to review and monitor processes, diagnose problems, and visualize data.
HMI technology is used by almost all industrial organizations
By allowing PLCs to communicate real-time information straight to an HMI display, HMI technology eliminates the need for this outdated practice and thereby reduces many costly problems caused by lack of information or human error.
Industries using HMI include:
- Food and beverage
- Oil and gas
- Water and wastewater
- And many more
The greatest advantage of an HMI is the user-friendliness of the graphical interface. The graphical interface contains color coding that allows for easy identification. Pictures and icons allow for fast recognition, easing the problems of illiteracy. HMI can reduce the cost of product manufacturing, and potentially increase profit margins and lower production costs.
HMI devices are now extremely innovative and capable of higher capacity and more interactive, elaborate functions than ever before. Some technological advantages the HMI offers are: converting hardware to software, eliminating the need for mouse and keyboard, and allowing kinesthetic computer/human interaction.
Unikie is certified to TISAX3 level, which means that Unikie’s operations meet the highest security standards set by the European automotive industry.
The criteria defined for the TISAX assessment level 3 concern companies that process highly sensitive product development information of their business partners.
We have been designing HMIs for a number of years and have a vast knowledge and understanding of what makes great user experiences.
Unikie’s HMI team helps Automotive OEM to reach the SOP
Our two years fruitful journey together with Automotive OEM will culminate in start of production. Soon also new car owners can experience the latest HMI technologies and features in Vehicle Infotainment Systems.
Unikie has been providing its competences on different domains in this IVI-project. Our focus has been on Navigation HMI and underlying services. Unikie’s HMI team was audited with SWEEP (Software Engineering Evolution Program) by our customer with a good score.
Along with the best practices the team did high quality development work and delivered on time. Our team is already on its way to make the next OEM more than happy.
Some key technologies and features which we have developed together with the customer:
- Real time traffic information over the VICS WIDE, IR beacons and ETC2.0
- Seamless integration of Electronic Toll Collection(ETC) with navigation HMI
- Providing driving safety features based on DSSS
- Detour feature based on the several traffic sources
- Two display solution in addition to cluster
