We present an experimental ergonomic evaluation of a contextual help system implementing human expert strategies. 18 potential users interacted with a standard text processor, using two help systems, a contextual one versus a non contextual one. Each system was simulated using the Wizard of Oz paradigm. The contextual help strategies were defined from the analysis of novice-expert dialogues.
