An open-source project developed with Unity3D and Photon to create a collaborative 3D virtual environment for academic and educational purposes.

The main goal of this project was to develop and validate a metaverse platform to support academics and students in collaboration and communication tasks. Concretely, the platform is a large room that implements general tools—inspired by real-world classes—to allow people to collaborate in different scenarios, e.g., conducting or attending lessons, seminars, talks, and working together.

• Creation and connection to a room. The platform offers real-time connection with other users, implemented through a room system, allowing users to choose whom to connect with. The first user intending to connect will create the room, providing it with a password, and then share this information with interested individuals.
• Free three-dimensional exploration. Freedom of movement and interaction characterize the virtual environment, allowing users to navigate any classroom area and engage with objects seamlessly through their avatar. Users can walk, sit, and interact freely with various objects in the scene. They can rotate their view and adjust the zoom level of their perspective as well.
• Avatar's customization. The user has the option to customize their avatar in various ways. The prototype includes a dedicated interface where users can make different appearance choices for their avatar, including skin color, uniform type and color, eye shape and color, eyebrows and possible beard, hairstyle, and a selection of some additional cosmetics like glasses or eye patches.
• Realistic voice communication. Users can engage in real-time communication with each other through voice chat. Using their microphones and voices, they can make their avatars speak and hear others as in genuine verbal communication. The voice chat is equipped with proximity and three-dimensionality features, allowing the tone of voice to vary based on the distance and position of the interlocutor.
• Text communication. It is also possible to communicate through text chat, which is readily available and visible in the platform's user interface.
• Non-verbal interaction. Various animations are available for avatars, and users can perform actions such as waving, clapping, or raising their hands.
• Projection and presentation of multimedia content. The virtual classroom is equipped with a projector to transmit multimedia content. Users can upload their slides or images and display them during the platform's runtime. The user can navigate the content on the projector with the presenter role. Each user can use the projector to showcase or present their materials and alternate this role with others during the session.
• Interaction with the whiteboard. The classroom also has a whiteboard where users can type and write using a keyboard. One user at a time can approach the whiteboard and start writing, and what they write will be visible to everyone, supporting interaction and communication.
