Using verbal protocols to support diagram design

Abstract

How do we know what people perceive in a diagram? A diagram can be an excellent medium for communicating complex facts and relationships. Users may be able to learn a lot just from a quick glance at a well-designed diagram. Unfortunately, what users take from a diagram may not always be the same as what its designers intended to communicate. This tutorial explores the use of verbal protocol analysis in the area of diagram interpretation, and offer practical support for systematic analysis procedures. This includes a close look at the way people formulate their thoughts about a design, which can reveal underlying conceptualisations and perspectives that the speakers may not be aware of.
