ImmersiveReach

Immersive Workspace for Accessibility & Reachability Calculations

Overview

ImmersiveReach is a specialized XR framework designed for calculating and visualizing accessibility in complex 3D environments. By providing high-fidelity spatial analysis, the workspace allows researchers to evaluate reachability constraints and plan delicate interactions with sensitive datasets.

While the framework is versatile, its primary application currently focuses on Preoperative Surgical Planning in Medical Domains. and Cultural Heritage and Archaeological Planning.
