I believe that interactivity comes from the use of our senses. Sight, touch, hearing, smell, and even balance. While not every interactive system needs to involve all of these senses, it must engage at least one. I agree with the idea that anything can be interactive because we can interact with everything around us. However, what’s crucial is distinguishing the level of interactivity (as he mentioned) whether it’s high, moderate, or low, since different forms of interaction have different impacts.
When the author claimed that printed books aren’t interactive because they can’t “speak,” I would argue that interactivity can also be one-sided. For instance, I am reading this author’s views, which may or may not influence or challenge my own thinking. The author created the book, and I am engaging with it—how can that not be considered a form of interaction? The experience of reading may not be a conversation, but it’s an intellectual exchange, a dialogue between the creator’s ideas and the reader’s mind.
Regarding Improving User Interaction in p5 Sketches I think allowing users more control over the artwork itself, such as changing colors, adding or removing elements, etc, could make the experience feel more personal and engaging. And offering users guidance on how to interact with the sketch, such as through on-screen prompts or hints, would help them understand how to navigate and manipulate the artwork more effectively. Also, adding sounds or auditory information. Though I haven’t seen any examples of that so I don’t know if It is possible.
