hmm I see your point- the definition is quite broad and general.
I do think that interaction design does tend to focus on digital experiences (bridging the virtual and physical).
But it might help to explain the specifics through an example from a company that does interaction design and/or a designer. I think for people who don’t know anything about it would need a concrete example.
So maybe if it were to be explained with an overview/broad definition and then paired with a specific of work done?
