Founded in 2022 by a group of grounded visionaries, HarvardXR is an organization based out of Harvard hosting annual conferences and exploring the boundary of digital realities. The 2024 annual conference Extended Intelligence focuses on the convergence of AI and XR. Our goal is to provide a platform for students, researchers, practitioners, and entrepreneurs to discuss how XR is shaping the future across different industries. We will delve into the history, present, and future of XR, and how we can leverage emerging technologies and challenges.
