- Smart cell-phones include many advanced applications and services, which allow their users to achieve various useful goals. However, many users face difficulties when upgrading their cell-phones devices to more advanced ones, partially because their applications include more complex patterns of use for achieving the users' goals. We present a conceptual framework that aims to help overcoming usage barrier by providing smart cell-phones' users a personalized knowledge service. The framework is based on the utilization of task models and on the tracking and analyzing the usage of the applications included in the smart cell-phone that enable to construct users' stereotypes and suggest personalized help according to their usage patterns. It is assumed that the system monitors the usage patterns of the user, thus enabling dynamic update of his/her belonging to a stereotype. The user can override the suggestions and navigate independently in order to find the required knowledge.
