Interactive 3D Printed Model

A 3D printed physical object augmented with technology that provides audio or other non-visual feedback when users touch or interact with specific areas. These models combine the tangible spatial information of a physical replica with digital annotations, typically using embedded sensors, NFC tags, capacitive markers, or computer vision-based hand tracking to detect which part of the model a user is touching and trigger corresponding audio labels. Interactive 3D printed models are particularly valuable in accessibility contexts for helping blind and low vision people learn about complex structures, scientific concepts, and spatial relationships that cannot be conveyed through text or flat tactile graphics alone.
