Users could give both feedback on the specific choices, or criteria for determining those choices, all in real time as the program is running. Users could supply commentary on both their own behavior and that of the agent, and the relationship between them. Users could also explicitly advise and modify the profile that Letizia forms of them. Mondrian takes advice from the user about how to learn new graphical procedures. Since the domain is graphical, often the advice comes in contextual forms.
Advice can be demonstrative.
In the beginning of the demonstration, specific objects can be designated as being examples, and that action advises Mondrian that any further operations involving these examples may be generalized in the future. Advice can be graphical. The user draws a diagram that shows Mondrian about part-whole relationships. In my experiments in a technical procedure domain, I allow the user to annotate selected frames of video by outlining images of parts, and grouping them into part-whole relationships. This means that when Mondrian records an action involving that part, it is described in terms of its relationship in the object's structure.
