    Did You Know What Is Augmented Reality?

    Make you crazy about games. One of the most popular games is a game that allows you to do a game between the virtual world and the real world that incorporates GPS navigation technology. Games that fall into the category of ‘augmented reality’ is actually not a new type of game. Create Android and iPhone phone users, games and ‘augmented reality’ apps have been available for a long time. Actually what is augmented reality?

    Understanding Augmented Reality

    Ronald T. Azuma (1997) defines ‘augmented reality’ as the incorporation of real and virtual objects in real environments, walks interactively in, real time, and there is integration between objects in 3 dimensions, ie virtual objects integrated in real world. The incorporation of real and virtual objects is possible with appropriate display technology, interactivity is possible through certain input devices, and good integration requires effective tracking.

    Before augmented reality, in 1994 Milgram and Kishino introduced the ‘virtuality continuum’. Milgram and Kishino formulated a possible framework for the incorporation and fusion of the real world and the virtual world into a continuum of virtue. The leftmost side is a real environment that contains only real objects, and the far right is a virtual environment containing virtual objects.

    In the embedded reality, which is closer to the left side, the environment is real and the object is virtual, while in augmented virtuality or virtity is enhanced, which is closer to the right side, the environment is virtual and the object is real. Reached reality and enhanced virtues are combined into mixed reality or mixed reality.

    3 Methods To Show Augmented Reality

    I. Marker Augmented Reality (Marker Based Tracking)

    There are several methods used in Augmented Reality one of them is Marker Based Tracking. Markers are usually black and white square illustrations with thick black borders and white backgrounds. The computer will recognize the position and marker orientation and create a virtual 3D world that is the point (0,0,0) and 3 axes that is X, Y, and Z. Marker Based Tracking has been developed since the 1980s and in the early 1990s began developed for the use of Augmented Reality.

    II. Markerless Augmented Reality

    One of the Augmented Reality methods currently developing is the ‘Markerless Augmented Reality’ method, with this method users no longer need to use a marker to display digital elements. As currently developed by the world’s largest Augmented Reality company Total Immersion, they have created various Markerless Tracking techniques as their flagship technology, such as Face Tracking, 3D Object Tracking and Motion Tracking.

    1.Face Tracking

    Using the algorithm they develop, computers can recognize the human face in general by recognizing the position of the eyes, nose, and mouth of a human, and then ignoring other objects around them such as trees, houses, and other objects.

    2.3D Object Tracking

    Unlike the Face Tracking that only recognizes the human face in general, 3D Object Tracking techniques can recognize all the forms of objects that are around, such as cars, desks, television, and others.

    3.Motion Tracking

    In this technique the computer can capture motion, Motion Tracking has started to be used extensively to produce films that try to simulate motion. An example is in Avatar movie, where James Cameron uses this technique to make the film and use it in realtime.

    III. GPS Based Tracking

    GPS Based Tracking Techniques are now gaining in popularity and are being developed on smartphone apps (iPhone and Android). By leveraging the GPS and compass features inside the smartphone, the app will retrieve data from the GPS and compass and then display it in the direction we want in realtime, even some applications show it in 3D.
