Drawing, writing, and painting on 2D surfaces in a real/physical space offers arbitrary interaction with a canvases in a cyber/virtual space of unlimited size. We propose Redirected Drawing, a novel methodology that applies visual manipulation to the user's drawing movement in a real/physical space to expand the perceived surface size required for the drawing experience in a cyber/physical space. To this end, this study specifically explores translation gain manipulation, where the displacement of a drawing stroke in reality is simply multiplied by a gain to represent it in VR. Our results show that pen-based drawing on a real/physical surface allows for a gain of up to 1.16 without being noticed by the user, which is more suited to expanding a cyber/virtual canvas size than finger-based drawing on a physical surface or in mid-air.

This research was accepted for a paper at the top virtual reality conference, IEEE Virtual Reality and 3D User Interfaces, held in Saint-Malo, France in March 2025, and was presented orally.
