A Virtual Environment for Collaborative Inspection in Additive Manufacturing
Extended Abstracts of the CHI Conference on Human Factors in Computing Systems(2024)
摘要
Additive manufacturing (AM) techniques have been used to enhance the design
and fabrication of complex components for various applications in the medical,
aerospace, energy, and consumer products industries. A defining feature for
many AM parts is the complex internal geometry enabled by the printing process.
However, inspecting these internal structures requires volumetric imaging,
i.e., X-ray CT, leading to the well-known challenge of visualizing complex 3D
geometries using 2D desktop interfaces. Furthermore, existing tools are limited
to single-user systems making it difficult to jointly discuss or share findings
with a larger team, i.e., the designers, manufacturing experts, and evaluation
team. In this work, we present a collaborative virtual reality (VR) for the
exploration and inspection of AM parts. Geographically separated experts can
virtually inspect and jointly discuss data. It also supports VR and non-VR
users, who can be spectators in the VR environment. Various features for data
exploration and inspection are developed and enhanced via real-time
synchronization. We followed usability and interface verification guidelines
using Nielsen's heuristics approach. Furthermore, we conducted exploratory and
semi-structured interviews with domain experts to collect qualitative feedback.
Results reveal potential benefits, applicability, and current limitations. The
proposed collaborative VR environment provides a new basis and opens new
research directions for virtual inspection and team collaboration in AM
settings.
