Chris Harrison is the Habermann Chair and
an assistant professor of human-computer
interaction at Carnegie Mellon University,
directing the Future Interfaces Group (www.
figlab.com). His lab broadly investigates novel
sensing and interactive technologies, especially
those that empower people to interact with
small computing devices in big ways.
I want to leave you with one final
chart: the Hype Cycle, created by
Gartner [ 16], which I’ve populated
with HCI areas from a 10,000-foot
perspective (Figure 8). Some people
hate this chart, but I find it to be a
useful visual shorthand to see where
things lie, and where HCI innovation
can have the most influence. I
encourage readers to plot their own
areas of interest on this chart (or
email me angry messages if I put
your field somewhere awkward).
The astute reader might notice
that this hype cycle curve is
not all that dissimilar from the
HCI Intellectual Impact Curve
I proposed earlier. Indeed, they
track fairly well, except for one key
difference: In the earliest stages,
external expectations are low,
but HCI innovation is highest.
This mismatch often means the
HCI community is the biggest
champion for a technology vision
and in no small part contributes
to the eventual peak of inflated
expectations. Getting people excited
about technology and drawing them
into our human-centered vision of
the future is an enviable position,
and so I have no qualms about
being off-cycle from the business
innovator’s dilemma. Yes, it does
mean that sometimes our research
and innovations get labeled as
esoteric and impractical, which has
significant implications for tax-
payer-funded science and education,
as well as for the sustainability of
industrial research labs. But it also
means we get to shape the narrative
and cast light on important human-
computer problems, hopefully with
broader impacts in mind [ 17]. This
is a great responsibility that we
should exercise and celebrate as a
community. So let’s pull out those
Post-its and markers and get to
