Tiltcasting: 3D Interaction on Large Displays using a Mobile Device
summary
Tiltcasting uses a smartphone tilt to cast a 2D plane into 3D and maps touchscreen position onto that plane; selection happens by releasing a finger and anything in front of the plane is temporarily hidden via occlusion removal. Implemented on an off‑the‑shelf phone and compared to Smart Casting with scenes containing 43 occluders, it matches ray‑casting on visible targets and is significantly faster and less frustrating for fully occluded targets; stereo rendering gives no benefit.
