[IxDA Discuss] Interaction design is design of time

[Challis Hodge]

I don't intend to be misleading I just don't agree with your definitions.
The diagram is intended to describe roles and how skill sets contribute to
various design efforts. The model also speaks to the evolution of design and
the addition of new roles over time to support needs in print then software
then web then mobile.

The classification illustrated by the diagram is misleading. Both UI
and IA should be viewed as branches of interaction design.

Why UI design is interaction design? Take a look at any illustration
of eye tracking of UI. They unfold in time. Hence guided time
perception is indelible from UI design. Users spend time looking and
discovering familiar patterns and use them as anchors for further
interactions.

Why IA is interaction design? It is primary goal is reducing time of
finding relevant information.

In this classification user experience is associated with interaction
design, even though it is indeed wider category (a lot of experience
is not designed).
