3d vr180 livestreaming system for semi-synchronous distance learning in tefl applications

VR video formats designed for use with head-mounted displays (HMDs) can be useful for immersive learning and allow students to freely focus their gaze on objects or people of interest. However, very little research has been done on the use of such technology as a medium-or long-term substitute for traditional classroom settings. This is particularly evident in the TEFL (Teaching English as a Foreign Language) field. To address the issue of providing an immersive, collaborative active learning environment while maintaining the privacy of individual students, a livestreaming system was created using 3D VR180 video (a stereoscopic video format that allows an HMD-wearing user to experience a 180-degree field of view). This system allows students to anonymously communicate with both the lecturer and one another on a message board using speech recognition software. To assess the potential of this system for expanded use, a mixed-methods approach involving qualitative user studies and quantitative benchmarking was undertaken.
