Abstract-In the past, the term E-learning was mentioned to any learning method that used electronic machine for the distribution. With the evolution and the apparition of the internet, the term e learning has been evolved and referred to the online courses. There are a lot of platform which serves to distribute and manage the learning content. In some domain learners need to use some equipment and useful product for purpose completing the image built in the theoretical part by the practical activity part. However, most of those platforms suffer from a lack in tools that offer practical activities for learners. Using videos, virtual laboratories or distance control of real equipment as solutions to solve this lack were proposed but still limited. The mixed reality as new technology promised to create a virtual environment where the learner is an actor and can interact with the virtual objects. This article present an approach for developing integrated E-learning systems, helping to carry out the practical work by establishing a virtual laboratory that all tools and products can be manipulated by learners and teachers like in real practical activity, based on an augmented reality system.

Abstract-The exponential growth of technology has contributed to the positive revolution of distance learning. Elearning is becoming increasingly used in the transfer of knowledge where instructors can model and script their courses in several formats such as files, videos and quizzes. In order to complete their courses, practical activities are very important. Several instructors have joined Multi-User Virtual World (MUVW) communities such as SecondeLife, as they offer a degree of interrelated realism and interaction between users. The modeling and scenarization of practical activities in the MUVWs remains a very difficult task considering the technologies used by these MUVWs and the necessary prerequisites. In this paper, we propose a framework for the OpenSimulator MUVWs that can simplify the scenarization of practical activities using the OpenSpace3D software and without requiring designers to have expertise in programming or coding.
