Chris Crawford begins the chapter with his own definition of interactivity:
a cyclic process in which two actors alerternaty listen, think, and speak.
I have read his definition of interactivity in another text he wrote and I agree with him and with the degrees of interactivity that he goes on to point in this chapter. Listening, thinking and speaking are all important aspects of an interface. Both sides need to be equal and while I agree with him on a lot of things, I don’t agree with his statement that books and dancing are not interactive. I personally think that you can have types of texts that are interactive and thus the term- hypertext. An example of hypertext could be “The Garden of Forking Paths”. I do, however, agree that movies are not interactive, nevertheless, there has been some progress in producers trying to make films interactive. A good example of that would be Netflix’s Bandersnatch.
