LEGO unveiled its latest web-based AR campaign which serves as an interactive product demo for the newly launched LEGO Hidden Side play sets, now in LEGO stores across the globe. The in-store activation challenges kids to help their LEGO friends, Jack and Parker, capture virtual ghosts who have escaped into their real world. From the WebAR experience, users can go directly to the LEGO website in order to learn more about the play sets, and they can also download the full mobile app. The campaign was produced by mixed reality agency Trigger using 8th Wall technology.
