This chapter provides a comprehensive and analytical view of the digital assistance concept. From a comprehensive point of view, it first describes assistance in the framework of some major trends in educational psychology, within which this concept does not appear as a component identified as such. The chapter also describes three of the four stages that make up the cycle of assistance: the response to an action/need, the processing/design methods considered, and its assessment from the different environmental factors integrated into the situation. It presents assistance as being characterized by an orientation which refers to the approach, chosen by the assistant, of which the assistance comes within the scope: reflective, communicational or curricular. However, the same assistance can be related to several orientations at the same time. It can also start an activity of the assisted person in a different orientation than that envisioned by the assistant.
