The GEAR.sg App displays the 3D models of The GEAR: Kajima Lab for Global Engineering, Architecture, & Real Estate located in Changi Business Park, Singapore. Through the smartphone camera, the building's 3D models appear on a set of picture cards illustrating the floor plans, which you can move, flip, and combine with the models on them. (Download the image files and print picture cards if you do not have them.) This AR app was created by MIT in collaboration with Kajima Development.
