The first thing that came to mind when the author was talking about how the word interactivity was used loosely, was AI. Funnily enough it goes hand in hand with interactivity in a lot of tech products, you will see “INTERACTIVE AND AI!!” plastered all around the advertisements when it really uses neither, and are just buzz words to attract customers. I had a similar idea of what interactivity is, to me it is a spectrum, we never say this is either interactive or not. We always say things like “oh this is really interactive,” or “this is somewhat interactive,” and so on. We always treated it as a spectrum, knowingly or unknowingly.
The problem with classifying if something is highly interactive is that, it’s all based on perspective, now what I mean by that is, treat the spectrum of interactivity as a battery with a fixed maximum capacity. A full charged battery would mean it’s highly interactive. The object defines the battery size, while the person’s perspective determines how much of that capacity is meaningful to them. This will make sense in a moment. There is objective traits to something being interactive, but how interactive it is will be subjective, for example, let us use the Nintendo fridge example with the kids and adults. The kids would tap into that battery supply and use most of it, while the adults would simply leave most of the battery unused.
Interactivity needs an initiator. a responder and a balance between that 2 that keeps the interaction in a meaningful interpretive cycle. This is true and can be objectively stated, however it is impossible to write a definition, or write what makes something highly or barely interactive as this will change person to person.
One thing this made me realize is that reactivity is not interactivity, and the sketches that we call interactive are simply just reactive to our inputs. To truly implement interactivity, I am thinking of making the program inputs less obvious, meaning the same input might lead to different actions depending on the context, making the user think about what to do.
