The global market for human-machine interfaces (HMI) reached 3.7 billion US Dollars and could grow to 7.2 Billion US dollars by 2026. HMI is an important factor in the future of automation. HMI allows humans and machines to communicate, making work more efficient and faster.

The economy and the workforce have been significantly affected by automation in the way workers interact with machines, leading toward a new human-machine interaction.

Future robots will be more sophisticated and able to perform more complex tasks previously performed by humans. The Human-Machine Interface will play a more significant role in how we interact with our devices. 

What is HMI?

HMI refers to all interactions between humans and machines, including everything from using a computer to perform an operation, to communicating with a virtual assistant using natural language processing.

Future automation will be determined by the advancement and use of automation technologies. The most popular forms of human-machine interaction are:

1. Operator interfaces

These are the controls that an operator uses in order to work on a machine. The most popular type is the graphical interface (GUI), which includes icons, images, and windows that allow users to interact with a program or machine.

2. Natural language processing (NLP)

Statista stated that the NLP market could grow 14 times until 2025 than it did in 2017, a rise of around 40 billion US dollars. This technology teaches machines how to understand human speech. It is increasingly used in virtual assistants such as Apple's Siri and Amazon's Alexa.

3. Augmented reality (AR)

AR overlays digital information and images on the real world to inform workers about the machines they are operating or their tasks. The most popular applications that use AR are Microsoft HoloLens and Google Glass.

4. Virtual reality (VR)

VR, like AR, is a technology that creates digital environments, but Virtual Reality replaces the actual world with a computer-generated version. It has the potential to train workers for future automation technologies.

5. Robotics

Robotics, a branch of engineering, deals with the design, construction, operation, and maintenance of robots. Robotics is a popular tool in manufacturing, but it's also becoming more widespread in other industries. It also allows for haptic feedback giving humans a chance to interact with machines by touching them.

According to recent statistics, approximately 400,000 new industrial robotics are used annually. South Korea has a high level of robotics density, with 900 robots for every 10,000 employees.

The future of automation is in human-machine interaction. Automation can be used to create a world that benefits everyone by leveraging the strengths and weaknesses of both humans and machines.
