persons is a metaphor used in job recruitment to
describe the abilities of persons in the workforce.
The vertical bar on the T represents the depth of
related skills and expertise in a single ﬁeld,

In design, human–computer interaction, and software
development, interaction design, often abbreviated IxD, is
"about shaping digital things for people’s use”, alternately
deﬁned as "the practice of designing interactive digital
products, environments, systems, and services."
What clearly marks interaction design as a design ﬁeld as
opposed to a science or engineering ﬁeld is that it is synthesis
and imagining things as they might be, more so than
focusing on how things are.
