Shift-Sliding and Depth-Pop for 3D Positioning

Explore two innovative 3D positioning techniques, Shift-Sliding and Depth-Pop, designed for mouse input but adaptable to other devices. Learn how these methods enable rapid and precise object placement in 3D scenes, utilizing sliding mechanics and frame buffer techniques. Discover how Shift-Sliding allows users to override default assumptions, manipulate objects in context-dependent local coordinate systems, and how Depth-Pop efficiently maps mouse wheel actions to object positions along the mouse ray. Examine the results of two user studies demonstrating significant speed improvements in common 3D positioning tasks, and gain insights into the potential applications and future developments of these techniques in 3D user interfaces.
