What is interactivity? How to use in English

The word "interactivity" can be traced back to the 1960s, when the term "man-machine" interaction was introduced to describe the communication between humans and machines. In the 1970s, this term evolved into "human-computer interaction" (HCI), which emphasized the importance of designing computer systems that were user-friendly and intuitive. The term "interactivity" emerged in the 1980s as a way to describe the two-way communication between users and digital media. It was coined to reflect the growing popularity of new technologies such as videogames and personal computers, which allowed for more sophisticated and engaging user experiences than ever before. Interactivity is often associated with multimedia, as it refers to the combination of text, images, audio, and video to create immersive and interactive experiences. This can take many forms, from interactive websites and online games to virtual reality environments and immersive theater productions. Overall, interactivity has become a fundamental concept in the design and development of digital media, as it allows for more engaging and personalized experiences that promote user participation and active learning.
