This course aims to help students invent and analyze new forms of extended reality (XR) experiences, computer-based art, gaming, social media, interactive narrative, and related technologies. This semester’s focus is on the theory, design, and implementation of experiences and technologies of virtuality. Toward this end, we shall look at topics including definitions of virtual, virtual reality, augmented reality, alternate reality, hybrid reality, virtual worlds, virtual selves, and more. We explore new expressive forms with a strong understanding of their historical antecedents, theoretical grounding, and social impacts with a special emphasis on the concept of “presence.” This grounding will help students to understand how each technology we investigate enables different user experiences of presence and how each technology offers its own opportunities, challenges, and possibilities. Students will participate in a range of new and ongoing projects that are designed to hone skills in research, development, design, and evaluation. The course is highly interdisciplinary, drawing upon the fields of cognitive science, media studies, and design. Finally, in line with the aims of the course and the urgent challenges posed by social distancing during the pandemic, we shall aim to discover new forms of remote-design practices that will be important for post-pandemic learning experiences
