Optimizing Screen Design for Natural Language-Based Knowledge Editing

A study that is still in an early stage focuses on the system WYSIWYM, which was developed by Dr. Richard Power of the University of Brighton (see http://www.itri.bton.ac.uk/projects/WYSIWYM/wysiwym.html). The system allows an expert in a given domain to encode knowledge in a language-independent form by formulating English-language propositions with the help of a sophisticated interface that includes menus and hyperlinks. An example of a general screen design issue raised by this system is the question of when it is advisable to supply an explicit abstract label (e.g., “Pronouns” or “Noun Patterns”) for a group of expressions from which the user can select–as opposed to simply letting the expressions speak for themselves. Analyses of data from the first few subjects have shown that this is one more issue on which eye tracking can yield valuable information.

The study was performed with the ASL Model 504 remote eye tracker; see the videos recorded during the eye tracking experiment.
