Core Concepts
An augmented reality framework that enables intuitive, in-place analysis of complex material data from X-ray computed tomography, integrating primary volumetric data and secondary derived attributes.
Abstract
The proposed framework leverages augmented reality (AR) technology to facilitate the immersive analysis of materials data obtained from X-ray computed tomography (XCT). It enables researchers and analysts to inspect material properties and structures directly on-site, providing a virtual workspace that seamlessly integrates the primary XCT volume data and secondary derived attributes.
The key aspects of the framework include:
Situated analytics: The physical material sample is recognized using image or shape tracking, automatically loading the corresponding XCT dataset. This creates a direct link between the real-world object and its virtual representation.
Embodied interaction: Users can manipulate the virtual data representations by interacting with the physical sample, enabling intuitive exploration through natural gestures and movements.
Hybrid visualization: The framework displays the primary XCT volume data alongside abstract visualizations of secondary attributes, such as histograms, scatterplots, and density plots. This allows for a comprehensive analysis of both spatial and non-spatial material characteristics.
Flexible workspace: The virtual visualizations can be freely arranged in the user's environment, providing a customizable analysis setup tailored to the specific needs of the expert.
The framework was evaluated through a user study with materials science and visualization experts. The results indicate that the immersive, situated approach significantly enhances the understanding of complex material data and enables more natural, efficient analysis workflows compared to traditional desktop-based systems.
Stats
"The CT dataset yielded a size of 250 × 250 × 300 voxels and contains 214 fibers, for each of which 20 distinct characteristics were computed."
"The investigated sample was cut out of a standard multi-purpose test specimen manufactured by injection molding."
Quotes
"The synchronization of translations and rotations between the physical samples and virtual representations creates a natural interaction, eliminating the need for traditional mouse and keyboard operations."
"Experts finally suggest that the system has significant potential for analyzing samples in combination with conventional analysis systems."
