This chatbot was trained on the UE5 portion of the wiki. This is an experimental chatbot, and we may incorporate more of the wiki's corpus into a chatbot in the future. The chatbot was trained using Chatfast.
In a collaborative group effort, we created a wiki that reviews the current state of software for creating virtual and augmented reality artifacts. This wiki is a resource for developers building VR software and experiences that target three software uses: development, modeling, and scientific visualization. We investigated the capabilities of software for head-mounted displays (HMDs), big-metal displays like caves and the yurt, and desktop displays. We considered software at different levels of the stack including graphics and visualization libraries, prototype application frameworks, game engines, and stand-alone applications. We evaluated these software via web research, hands-on case studies, and surveying. In addition, we created tutorials for selected software and workflows.

1.3.1. VR in Education
Studies have shown that individualized learning helps students achieve their academic goals at a faster pace. Today, classroom structures are not so different from the structure years ago—teachers create a curriculum for the entire class, and students typically learn at the same pace. Virtual reality learning environments can change that. With VR, students can personalize their learning, choosing how long to spend their time on certain concepts, and walking through simulations themselves. VR environments can increase both motivation and hands-on experience.
