The Microsoft Mesh application also enables remote collaborative work via avatars animated with MR. Users wear a HoloLens 2, and in a digitally augmented environment, they are represented as avatars to collaborate, converse and train with their colleagues . This tool is usable and easy to use, with low demand in terms of cognitive load . Surprisingly, MR was never applied before in the battery field before. To summarize, previous reports have shown that training with MR and VR will help in the creativity and easiness to learn new tasks. In this Concept, we present an innovative digital educational tool combining VR with MR that facilitates users' experiences in a battery prototyping room.
