In augmented and virtual reality (AR and VR), there may be many 3D planar windows with 2D texts, images, and videos on them. However, managing the position, orientation, and scale of such a window in an immersive 3D workspace can be difficult. Projective Windows strategically uses the absolute and apparent sizes of the window at various stages of the interaction to enable the grabbing, moving, scaling, and releasing of the window in one continuous hand gesture. With it, the user can quickly and intuitively manage and interact with windows in space without any controller hardware or dedicated widget. Through an evaluation, we demonstrate that our technique is performant and preferable, and that projective geometry plays an important role in the design of spatial user interfaces.
