Projective Windows: Bringing Windows in Space to the Fingertip
summary
Technique lets users grab distant 2D windows and keep apparent size constant by shrinking absolute size, then move, scale and project them onto surfaces with one continuous hand gesture. Implemented on an Oculus Rift + Leap Motion prototype (quantitative tests use a controller because Leap tracking is noisy). Users perform 420 move/scale trials and the controller-based method is 22% faster with ~40% fewer operations than ray-casting with widgets; participants learn it quickly and prefer it for casual tasks.
