The metaverse, with the internet, virtual and augmented reality, and other domains for an immersive environment, has been considered mainstream in recent years. However, the current metaverse platforms have a gap in the physical space, leading to reduced engagement in these applications. This thesis project explores an extended metaverse framework with generative content and the design of a seamless interface to increase the connection between the metaverse and the physical environment and create coherence and efficiency between them. The extended metaverse agent helps prevent this from happening by improving the interaction, embodiment, and agency that dynamically engage humans in mixed reality (MR) environments. This thesis project will design and prototype MR objects and environments with the research through design (RTD) and speculative design methodology, whereby future applications are imagined, assuming plausibility of smart glasses being commonplace to help users visualize the coherence of virtual and physical spaces in simultaneity. To summarize, this thesis project provides an extended metaverse framework and agent that generates from physical contexts to describe the coherence of virtual and physical environments.
