AI Technical Summary
Existing extended reality (XR) scene description technologies face challenges in accurately describing and rendering interactions between virtual objects, particularly in scenarios involving proximity triggers, which are crucial for immersive experiences but often limited by geometric simplicity and incompatibility with standard scene description formats.
The introduction of additional geometric primitives, such as spheres, boxes, and cylinders, within the XR scene graph to define 3D regions for proximity triggers, enhancing interaction accuracy and compatibility with formats like glTF and MPEG extensions, allowing for more complex and realistic user interactions.
Enables precise and versatile interaction scenarios, including social behaviors and privacy considerations, by defining geometric primitives that enhance the XR experience with improved triggering mechanisms and compatibility with existing scene description standards.
