To summarize, Professor Franco's team has already developed several tools using VR, and Simubat 4.0 Gen-2 is the first one to combine VR and MR. To our knowledge, there is no training tool on battery manufacturing processes that couple VR with MR. The aim of this article is twofold: firstly, to study the usability and usefulness of Simubat 4.0 Gen-2 from a pedagogical point of This tool has been designed to help novice users understand the highly complex manufacturing process and the composition of the cells by placing users as actors rather than observers.
