Most interface designers assume that users actually want to use their software. But what if focusing on the software is the last thing a user should do? Pathfinder Development introduces the concept of designing "Invisible Interfaces" for this type of user, and illustrates our point with examples from a recent project for health care providers.

7. An Invisible Interface:
• Accommodates the notion that
interacting with the software is not
the primary goal or responsibility
of the user
• Allows operation without looking at
the interface
• Reduces the time it takes to
perform data entry
• Critical in workplaces where using
software is a distraction from
someone’s primary responsibility

about it - we don't even have to
demo it, [the phlebotomists] just
take it out of your hands and start
using it.quot;
