In this paper we describe our approach the aim of which is to apply MOCOCO concepts to e-learning. After a brief presentation of MOCOCO (Mobility, COoperation, COntextualisation) and IMERA (Mobile Interaction in the Augmented Real Environment) principles, we will in turn describe m-learning scope, contextualisation and cooperation advantages as well as learning methods. We will then discuss Contextual Mobile Learning in a project known as HMTD (Help Me To Do), aimed at using wearable computer in a context of activities for better use, maintenance and repair of domestic and professional appliances. This paper ends with an explanation of the overall organisation of our Contextual Mobile Learning system.
