Geomath: An Augmented Reality Based Geometry Introductory Android-Based Application with Cuboid Tracking

摘要

Geometry is the lesson we have learned from the elementary school level, which is divided into two categories: plane geometry and solid geometry. The shapes of geometrical objects can be around us in our everyday life, such as dice with cuboid shape, door with rectangular shape, plates with circular shapes, etc. Even so, the apparatus used for introducing these shapes are many still in the form of books or static media or objects. In this research, innovation is made by creating an application that will show geometry planes and objects using Augmented Reality technology and the 3D Cuboid Tracking method. This method uses a cuboid-shaped marker that has six sides and can be tracked all at once. By using this method, the geometry objects can be seen in 3D, where users can see every object at a different angle and gives better haptic feedback as the cube can be held. In this research, we use ten geometry objects that consist of six solid geometry objects (cube, rectangular prism, triangular prism, sphere, cylinder, cone) and four plane geometry objects (triangle, rectangle, square, circle). This application shows geometry objects with its description and the calculation of surface area, volume, and perimeter and a quite accurate projection with less than 0.5 cm margin error. A test of the application also has been done on Android smartphones and successfully installed on Android 5.1 and higher versions.
