User interaction management techniques are disclosed. In a first aspect of the invention, an automated technique for managing interaction between a user and a system includes the following steps/operations. One or more behaviors associated with a user are observed as the user interacts with the system. A skill level of a user accessing the system is determined. Then, a user interaction profile is modified based on the determined skill level of the user. In a second aspect of the invention, an automated technique for generating a skill level classifier for use in classifying users interacting with a system includes the following steps/operations. Input from multiple users having various skill levels is obtained. Then, a classifier is trained using the obtained input from the multiple users such that the classifier automatically detects in which category of interaction skills a subsequent user belongs.
