Geometry learning tool for elementary school using augmented reality

Augmented Reality is a technology that overlay the virtual objects into the real world. With the capabilities of Augmented Reality in combining virtual and real world object in real time, it can be utilized to help education process for elementary students. There are numerous frameworks to build Augmented Reality based application. OpenCv is a computer library vision that implements various tools for processing images. The purpose of this research is to test whether OpenCv is capable to build Augmented Reality based application or not. With the capabilities of OpenCv in detecting color and registering the virtual object in real time, it supports the Augmented Reality based application creation. The research is done by creating the Augmented Reality Geometry Learning Tool prototype system based on OpenCv to help elementary students learning using protractor. The prototype system then is implemented in the elementary school to obtain the response from the students. The response from the student is satisfying and it proves OpenCv is capable to build Augmented Reality based application.
