  Mixed Reality aims to merge the digital and physical worlds to create
immersive human-computer interactions. Despite notable advancements, the
absence of realistic haptic feedback often breaks the immersive experience by
creating a disconnect between visual and tactile perceptions. This paper
introduces Haptic Repurposing with GenAI, an innovative approach to enhance MR
interactions by transforming any physical objects into adaptive haptic
interfaces for AI-generated virtual assets. Utilizing state-of-the-art
generative AI models, this system captures both 2D and 3D features of physical
objects and, through user-directed prompts, generates corresponding virtual
objects that maintain the physical form of the original objects. Through
model-based object tracking, the system dynamically anchors virtual assets to
physical props in real time, allowing objects to visually morph into any
user-specified virtual object. This paper details the system's development,
presents findings from usability studies that validate its effectiveness, and
explores its potential to significantly enhance interactive MR environments.
The hope is this work can lay a foundation for further research into AI-driven
spatial transformation in immersive and haptic technologies.
