Hand motion and pen drawing can be intuitive and expressive inputs for professional digital 3D authoring. However, their inherent limitations have hampered wider adoption. 3D sketching using hand motion is rapid but rough, and 3D sketching using pen drawing is delicate but tedious. Our new 3D sketching workflow combines these two in a complementary manner. The user makes quick hand motions in the air to generate approximate 3D shapes, and uses them as scaffolds on which to add details via pen… 
HandPainter - 3D Sketching in VR with Hand-based Physical Proxy
TLDR
HandPainter is designed, a VR sketching system which focuses on the direct use of two hands for 3D sketching without requesting any tablet, pen, or VR controller, and is based on a pair of VR gloves, which provide hand tracking and gesture capture.
3D Sketching for Multi-Pose Products: An Interactive Showcase
TLDR
This interactive showcase presents a 3D sketching system for multi-pose products that lets designers easily sketch 3D curves, and part, rig, and pose them, and demonstrates that, with interactions that closely resemble traditional 2D perspective sketching and the physical manipulation of an articulated object, designers can quickly try many different form and movement ideas in 3D during the early stage of design.
3D Sketching for Multi-Pose Products
TLDR
This study shows that, with interactions closely resembling traditional 2D perspective sketching and the physical manipulation of an articulated object, designers can focus solely on ideating, iterating, and communicating multi-pose product concepts during the initial stage of design.
VRSketchIn: Exploring the Design Space of Pen and Tablet Interaction for 3D Sketching in Virtual Reality
TLDR
VRSketchIn is presented, a VR sketching application using a 6DoF-tracked pen and a 6 doF-Tracked tablet as input devices, combining unconstrained 3D mid-air with constrained 2D surface-based sketching.
ScaffoldSketch: Accurate Industrial Design Drawing in VR
TLDR
An approach to in-air design drawing based on the two-stage approach common in 2D design drawing practice, which shows that accurate industrial design drawing in 3D becomes tractable when decomposed into auto-correcting scaffold strokes, which have simple relationships with one another, followed by auto- correcting shape strokes with respect to the scaffolds.
Smart3DGuides: Making Unconstrained Immersive 3D Drawing More Accurate
TLDR
A set of common mistakes that users make while creating freehand strokes in VR are identified and a set of visual guides are designed, the Smart3DGuides, which help users avoid these mistakes.
Mobi3DSketch: 3D Sketching in Mobile AR
TLDR
Mobi3DSketch is presented, which integrates multiple sources of inputs with tools, mainly different versions of 3D snapping and planar/curves surface proxies, and supports both absolute and relative drawing, allowing easy creation of3D concept designs in situ.
CASSIE: Curve and Surface Sketching in Immersive Environments
We present CASSIE, a conceptual modeling system in VR that leverages freehand mid-air sketching, and a novel 3D optimization framework to create connected curve network armatures, predictively
Bi-3D: Bi-Manual Pen-and-Touch Interaction for 3D Manipulation on Tablets
TLDR
The Bi-3D design space is described, crossing two-handed input and the degrees-of-freedom (DOF) of 3D manipulation and navigation tasks, and bi-manual 3DOF input is evaluated against widget and mid-air baselines in an object movement task.

Experimental Evaluation of Sketching on Surfaces in VR
TLDR
A set of controlled studies to analyze the factors affecting human ability to sketch freely in a 3D VR environment indicate that the lack of a physical drawing surface is a major cause of inaccuracies in VR drawing, and that the effect is dependent on the orientation of the drawing surface.
