Like any personal visual analytics application,
the design of the visual interface has to be easy to
use for nonexpert users. The design should be intuitive
and not require a steep learning curve. The
automatic processing for the analysis should be robust so that there is little or no need for the user to
interfere and fine-tune data mining or computer
vision techniques. Similar to many of the apps in
mobile personal use on smartphones, visual analytics
software for personal eye tracking will most
likely be application-specific.
