ConclusionConclusion

• Advantages– Merging between human factors (task) and software

design (object)

– Precise description of the dialogue control

– Computer supported generation and automatic management

• Shortcomings– Improve the help management

– Link the tool with evaluation tools

– Design from interaction objects
