It's a special floor made for virtual reality (VR) experiences. Invented by Lanny Smoot from Disney, this floor is unique because:
1. Many people can use it at the same time.
2. Users can walk in any direction they want.
3. It helps prevent people from bumping into each other.
This is a big step in VR technology. It can be used in many ways, like in games or training. It's also important for AI because it can help in creating more realistic and interactive VR worlds. This technology can teach AI how people move and interact in virtual spaces.
