Eye-tracking 2.0: it's about users, not science
Eye-tracking has been used in web design for many years.
However, the widespread preconception is that it takes PhD skilled
technicians - plus long consulting hours - to make any sense or use
of people's eye gaze data.
The value from eye-tracking has been directly related to
consultancy skills, but shouldn't it be more about real users?
Eye-tracking has been used mainly as a qualitative tool because
of technical reasons. The hardware was difficult to operate and
only few consulting houses had the access and capability to run the
tests in their lab conditions. Operating labs and recruiting people
from consumer panels is expensive and forced consultancies to stick
with small sample sizes to fit into client's budgets. Small sample
sizes have held back the wider acceptance of eye-tracking analysis
in web design.
In 'Eye-tracking 2.0' devices will be taken to users, not users
to devices. This fundamentally changes the speed and sample size of
users who can be eye-tracked for analysis purposes.
Quantitative eye-tracking speaks the voice of the customer, not
of the consultant. It takes to test about 50 people (why?) to achieve
reliability in the visual analysis for any piece of media.
Statistical significance of this sample size allows conveying real
user design preferences in neutral and objective manner. Visual
metrics and animations of user interaction gain their own
stand-alone value as models of real user behavior on designers and
marketers desktops.
Consultant expertise and qualitative insights are extremely
valuable, quantitative eye-tracking complements them with sound
numbers. Technological progress has made data collection procedures
and packaging 'a standard issue'. Professionals can now spend their
time on more demanding and value-adding activities than running
user tests or analyzing gigabytes of eye-tracking data.
Reliable quantitative visual analysis is now available as a
given tool and consultants can focus more on fundamentals. Much
like fund managers do when using outsourced data feeds, but making
their own investment decisions.
Eye-tracking was often oversold in the past, creating
well-deserved skepticism towards the technology. The
'before-and-after' case studies of websites being redesigned based
on only heatmaps of 10 people rightly upset many industry
professionals.
As eye-tracking hardware improves and operational models for
analysis develop there will be less 'magic' and more of the real
stuff: identifying user preferences and employing that knowledge to
achieve better web design.
