Physical Guides - An Analysis of 3D Sketching Performance on Physical Objects in Augmented Reality

Explore a conference talk that analyzes the performance of 3D sketching on physical objects in augmented reality. Delve into the advantages of using real-world objects as guides for creating 3D designs in AR, including natural haptic feedback and improved accuracy. Learn about the categorization of guidance types into flat, concave, and convex surfaces, edges, and surface markings. Discover the results of a study comparing sketching accuracy on physical versus virtual objects in AR, revealing a 48% improvement in accuracy when tracing physical objects. Gain insights into the implications of these findings for designing AR sketching systems, particularly in the context of personal fabrication and non-professional design. Recorded at the ACM Symposium on Spatial User Interaction in Berlin, this 31-minute presentation offers valuable metrics and considerations for AR sketching system development.
