In this paper we describe our approach whose objective is to apply MOCOCO concepts to e-learning. After a short presentation of MOCOCO (Mobility, Cooperation, Contextualization) and IMERA (Mobile Interaction in the Augmented Real Environment) principles we will discuss their use in a project called HMTD (Help Me To Do) whose aim is to use wearable computer for a framework of activities of better use, maintenance and repairing of professional appliances. We will successively describe m-learning scope, contextualization and cooperation advantages as well as learning methods. A case study of configuration of wearable computer and its peripherals, taking into account context, in-situ storage, traceability and regulation in these activities finishes this paper.
