The Future Is Virtual
If you inspect VR or AR, it becomes clear the definitions are ever shifting with the technology. In the most basic sense, they mean the same (the interaction between humans and machines using visualization and physical movement rather than mouses and keyboards), but they differ and can cause misunderstandings. To make it easy, AR still incorporates the real world, where VR attempts to replace it.
Since software and technology are constantly being developed, alternative forms of virtuality keep being added. Eventually, they must be explained and named.
No matter what we call this technology, humans will continue to find new ways to use data to enhance the analog world to improve work and play. Starting to explore these technologies now means there will be less of a knowledge gap when AR, VR, and/or MR become commonplace in the world of work.
