I feel we have a language issue here... "elements" seems to mean
something for someone and more a general thing for others.
what do you mean by elements, then?
from what you wrote in your blog they seem to describe the elements to
consider when designing a product (digital or analog). People and
Context is shapes, constrains and influences the design. So how would
you call these 3 things (element, people, context) as a whole?
IMO, the title "_the_ elements of IxD", calls for the things we need
to look at/think about when doing IxD.
