The author mentioned that big intricate topics like interactivity can’t be boiled down to a simple definition, and I fully agree with that statement. I found the definition he set lacking but then again so are most definitions for complicated topics. One thing I would disagree with him on though, is him dismissing the fridge opening as interactivity. It is indeed interactivity, albeit weak interactivity, as it fits everything he described earlier in the reading and he admits that, but then he dismisses it anyways. Also I really liked what he said about participation not being interactivity, the concepts didn’t have a clear distinction in my head, but he does a good job of explaining them. Lastly, regarding what the author mentioned about movies not being interactive, interactive movies actually exist now! Like the movie In Limbo https://inlimbo.tv/en/
