Folding Rays

Crossing a second ray from the other hand with the main ray marks a fold point; a camera placed there shows its view in a window, and the ray continues through that window, so it can bend around occluders as many times as needed.

How it works

With two VR controllers, the point where the off-hand ray comes close to the main ray is shown as a sphere, and a button creates a camera there facing the user's view direction. Its view appears in a window 1.5 m in front of the user that follows the head, and the main ray pointed into the window continues from the fold point; new folds can be made inside the window. The trigger selects the object hit. No user study was reported.
