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. Advice can be verbal . A speech recognition system is trained to recognize a set of visual relations, constraints, and predicates that modify the actions the user is taking or objects that the user is manipulating.
