Keywords – impossible object, binocular-disparity adjustment, redirection techniques, multimodal interaction
Summary – Interactive Impossible Objects is a VR system that turns classic impossible objects into walkable, touchable experiences. By rendering different 3D models for each eye and using redirection techniques, it preserves the illusion while mapping real objects onto impossible virtual shapes. Users can seamlessly climb an “endless” staircase and interact with impossible objects in VR alongside their physical counterparts.
