This hyperthesis or ebook is obviously not "real" in the sense that it is not physically embodied and only exists as it is displayed on the computer screen. But it is "virtually" real, in that you are able to read it and manipulate it in a number of ways, and in that it can be copied and screens printed out. The concept of virtuality is intrinsically digital, since the copy both exists (1) and does not (0). (Data is stored digitally as 1s and 0s.)
In fact, the "book" which you see on the screen exists for only so long as you read it. The primary copy remains in the memory of the computer or on CD Rom, while the computer creates an electronic copy for you to read. If you are also able to write on the book - to add to it or to make changes - the computer will then store your version when you "save" it, but the version which you next see on screen will still be a copy of your stored version rather than the version itself.
In virtual reality, the use of goggles, earphones, a data glove and occasionally a full body suit (which provide the user with the means of controlling activities and occasionally providing sensory feedback) offers the user the illusion of participating in an artificially created world. See for example Black Ice, January 1993, pp12-25.
