The 3D Space Building Recognition Application is an application designed to facilitate the student learning process. This application uses augmented reality technology which is able to improve students emotional abilities in absorbing information. This application provides 7 geometric shapes, namely cubes, beams, triangular prisms, triangular pyramids, rectangular pyramids, tubes and cones.By using this application, students can carry out learning by scanning an available two-dimensional geometric image using a smartphone camera, and digital elements such as 3D images, sound, and spatial material will appear. In addition, there is a quiz that displays use values to measure students understanding of the available geometric material.
