What happens when AI, immersive tools, and social platforms converge in XR design? This session investigates how designers can leverage hybrid workflows—blending desktop modeling with immersive in-headset tools—for rapid, iterative prototyping. We’ll explore how traditional UX/UI principles translate into spatial experiences, the potential of AI to accelerate ideation, and the strategic implications of choosing between closed systems like Unity-based XR apps or open, community-driven environments like Horizon Worlds.
