Before using the BMM, users can create their avatar that will be visible in the application by going through a weblink service provided by Ready Player Me (Figure ). A user entering the application sees a screen where she/he can view her/his avatar and the eight rooms available on the server (Figure ). Each room is an instance of the BMM. This feature allows multiple individual sets of virtual "classrooms" which can be hosted simultaneously. Any number of users can join a particular room, and any number of rooms can be created if necessary, as the main limitation is determined by the server's hardware capacity. However, considering optimal ergonomics, the number of users is limited to six. This limitation is designed to maintain a comfortable and manageable environment for all participants. A balanced number of users helps maintain clear communication and engagement, ensuring everyone has the chance to learn and contribute meaningfully. Once a user enters any room, the virtual pilot line and the other users present in the room become visible.
