VRSmartphoneSketch: Augmenting VR Controller With A Smartphone For Mid-air Sketching

Abstract

We propose VRSmartphoneSketch, a mid-air sketching system that combines a smartphone with VR controllers to allow hybrid 2D and 3D inputs. We conducted a user study with 12 participants to explore the utility of the hybrid inputs of the bundled smartphone and controller when there was no drawing surface. The results show that the proposed system didn’t significantly improve stroke accuracy and user experiences compared with the benchmark controller-only drawing condition. However, users have given positive feedback on the stability and sense of control of strokes brought by the smartphone’s touch.
