Implementation of Augmented Reality Geolocation Application Based on Android for Searching Hospital Location

A navigation field now has been dominated by Google Maps, where the conventional map information is converted into a digital map. The disadvantages of that digital maps are the user cannot find out the real direction to the destination, whether it located in the front, in the back, in the right, or in the left of user. Technology of augmented reality can be used to cover the lack of digital maps. It requires access to the camera, accelerometer sensor, digital compass, and GPS that are embedded in the android smartphone. Data from the GPS generate the azimuth angle and the angle of inclination that formed between the positions of the user with location and then converted to the form of augmented reality marker on the screen. According to the azimuth angle and direction of the compass, it can be known the horizontal position of the hospital on the screen. While the angle of inclination and orientation of the accelerometer determines the vertical position of the hospital on the screen.
