Fluid3DGuides: A Technique for Structured 3D Drawing in VR

We propose Fluid3DGuides, a drawing guide technique to help users draw structured sketches more accurately in VR. The prototype system continuously infers visual guide lines for the user based on the user’s instant stroke drawing intention and its potential constraint relationship with the existing strokes. We evaluated our prototype through a pilot user study with six participants by comparing the proposed guide technique against the non-guide drawing condition. Participants gave positive comments on ease of use and drawing accuracy. They found that the technique could reduce the time and effort required to find the corrected drawing perspective and obtain more accurate 3D structured sketches.
