Rapido turns a non‑interactive AR video into a working prototype by letting designers record input taps and world touches, record animation finger paths and sketches on a mobile device, then inferring an executable state machine and showing it in a timeline view. It computes world positions by raycasting to planes, attaches sketches to screen or world, and builds a testable AR prototype in under ten minutes that reproduces selection, placement and repositioning interactions.
