A system is strongly interactive when the user can change its outcome. Crawford simplified interactivity as listening, thinking, and speaking, which can also be understood as input, processing, and output. For example, take a storybook. A book is not interactive, as the reader cannot influence anything that happens in its narrative. A video game, however, is interactive because the player can control the character with an input, altering its journey. In my opinion, this is what makes a strong interactive system: the user’s input has a noticeable impact on the system’s response.
While making future sketches, I plan to incorporate interactivity by using functions on P5.JS such as mousePressed and mouseX/mouseY to give my projects more interactivity. I have already started this in my last artwork, as I used mousePressed and a boolean variable to change the color of the piece.
