It’s a nice look into how we can answer the question “But, what is interaction design?”
I was lucky enough to see him speak at a conference last year about ‘How do I think new things?” and the concept he called ‘semantic noodling’. I think he’s one of those people with very infectious knowledge and obviously delights in what he does and speaks about.
Also well worth reading his book “Make it so” lessons we can learn in design from science fiction.
Hope you enjoy.
