Virtual reality technologies are promising to effectively enhance our daily experiences. Enhancing learning experiences with virtual reality technologies is one of important directions to make the technologies change our daily lifestyle, because students in classes need not gather together in the same location. However, virtual reality technologies offer plausible feeling to them residing in the same location. Students can attend their classes anytime anywhere from their mobile virtual reality (VR) devices, but they feel to take a class in the same class room. Moreover, virtual reality technologies can provide additional effects that cannot be realized in traditional real-world class rooms. The paper proposes VR Classroom that offers a virtual space where students and a teacher virtually reside in the same location. VR Classroom also provides several features to motivate students through fictionality realized by virtual reality technologies. After describing an overview of VR Classroom, we show its prototype implementation and user study.
