People can interact with artificial systems with the help of interfaces that bridge the gap between humans and their technical environments. For the purpose of man-machine communication, the technology is modified to meet the needs and abilities of people and integrated as inconspicuously as possible into processes.
The computer mouse was one of the very first interfaces, and is still the most important one. It was invented in the second half of the 1960s. But natural, intuitive interaction with artificial systems must be aimed directly at the senses and at human beings’ means of communication, such as sounds, facial gestures and gestures. Virtual and digital space becomes ever more realistic with the help of haptic interfaces in which human beings can directly use their sense of touch.
Interfaces that are placed directly on the body are called wearables. Yet another level is reached when humans have technological interfaces implanted into their bodies. Cyborgs are individuals in which the human being and the machine have ultimately merged.
