This course aims to empower students with the principles and techniques to harness the emerging interactive and display technologies to take advantage of the experience and knowledge learnt from the 3D digital content and virtual world creation paradigm to unleash the creative potentials of Extended Reality as an unprecedented storytelling medium. Extended Reality (XR) is a superset of all the technologies that includes Virtual Reality (VR), Augmented Reality (AR), Mixed Reality (MR), and anything within the spectrum of reality-virtuality continuum. Students will not only acquire a broad and comprehensive background of the histories, concepts, and principles of XR but also have solid practices down to specific realtime and cinematic VR/AR productions. Students will be able to apply the principles that transcend all forms of Extended Reality to inform the productions for burgeoning modalities of interacting with physical and virtual spaces. After finishing this course, students are able to extend their knowledge and workflow from traditional 3D content creation to different forms of Extended Reality to develop creative works in way that have never been seen before.
