Experiment Design with Wizard of Oz Prototyping
summary
Claims that Wizard of Oz prototyping reveals real user intent by faking capabilities long enough to observe behaviour; builds include a wired test house with floor sensors, a 3D-printed button, tablet UI and a projection on the floor to compare tap/touch/talk interactions, which shows projection preserves continuity and invites distant voice use. GoPro case: users submit ~30 GB of raw footage, highlights map to 5-second highlights, a tap-to-mark Wizard‑of‑Oz editor snaps clips to smart music templates, cuts editing time from hours to minutes and drives the AI and hardware roadmap.
