Dewata Nawa Sanga Essay

Markerless Augmented Reality Utilizing Gyroscope to Demonstrate the Position of Dewata Nawa Sanga

Abstract — Dewata Nawa Sanga in Hindu Religion in Bali has an important role as the foundation of the religious concept implemented by Hindus in Bali. Dewata Nawa Sanga has the meaning of nine deities or manifestations of Ida Sang Hyang Widhi Wasa that guard or control the nine directions of the wind. Dewata Nawa Sanga in terms of education in the province of Bali has actually entered the curriculum of elementary school students. But in social life, the concept of Dewata Nawa Sanga itself has not been so attached and understood by all people. Moving from the problem, rised an idea to develop Markerless Augmented Reality Utilizing Gyroscope to
DewataAR application uses brochures as a Marker to display Augmented Reality which is a video, 3 dimensional objects, and audio that become the advantages of this research. However, this study has the only shortcomings of using brochures as a Marker that is easily to lose if the user is messy. [4] In Augmented Reality technology, the concept of introducing images, object recognition and 3 dimensional object tracking is not a new concept and has been used primarily by markers in visual form. This visual marker has been widely used in some Augmented Reality applications in several studies. In the majority of these applications, to realize the performance of the Augmented Reality system is highly dependent on the tracking method using marker detection, pose estimation, and so forth according to the application. However, the use of this marker may result in limited interactivity restricted to a wide range of images and objects realized in the form of borders and barcodes to create markers. Therefore to realize this approach, this marker mark must be printed and also stored for future use of this application. Unlike Augmented reality technology that uses marker bases, in a markerless based augmented reality system, any part of the environment can actually be used as a target or marker, so that each coordinate position can be traced to place virtual objects in both 2D and 3D form. [5] Based on that assumption markerless augmented reality is an interesting technology to develop. Markerless Augmented has many types among others, combination with GPS, motion, face tracking and the balance of orientation with gyroscope sensor. Gyroscope is a tool to measure orientation based on the working principle of angular momentum. Gyroscopes are widely used to measure angular velocities, how fast something rotates around an axis. And most
