How Do Augmented Reality Apps Work? Some Key Essentials

How Do Augmented Reality Apps Work_

The latest trend for mobile devices, augmented reality is around for quite a few years now. This technology captures the information on an image and can be seen from the camera of a mobile device. Smartphone technologies like accessories and GPS, displays and processors make the whole process of augmented reality possible. In recent times many android and iOS apps have started providing the augmented reality experience. Augmented reality provides an engaging experience to the users, helping in marketing the product in a unique way. Since the technologies of smartphones are not developed, with augmented reality in mind, it becomes challenging to maintain the accuracy of the app across devices.
The quality of the compass of a device also plays a major role in the development of the AR app. The GPS on most smartphones is not 100% accurate and this poses a challenge as well.

How to Develop an AR App For Android?

Augmented reality is an arena that many Android developers are exploring these days. As a developer, one can do with the existing programming language to be able to develop an augmented reality app.
Some companies have also come up with specialized SDKs for augmented reality apps. These can also be used to build apps, based on this technology. Google Glass is an example of a branded technology in this space.
Many companies are competing in this space to create standards and benchmarks for development of AR apps. It is not a compulsion to build AR applications using branded technologies. AR can be used as a function and can be added to existing technologies as well.

Here are some key to do’s while creating an AR Application with Android:

Camera

For fetching the data from the smartphone’s camera, one can fetch the data from the API’s available in android.hardware.camera. The idea is to use the live feed from the camera. There is an option to use the frame data or the surface view in this case.

Location

The second most important data one requires while creating an augmented reality app is the location of the device and the user. This can be accessed from the location APIs available in the android.location package. This will help the application to access the relevant line item, based on the location of the device. ‘Markers’ and ‘Tags’ can also be used in the absence of location data.

Sensors

The smartphone orientation is an important aspect of AR implementations. This helps in fetching a more accurate feed from the camera. The API’s in this case can be accessed from android.hardware.SensorManager package. The movement of the device is accurately captured in this case and makes the app experience much more engaging for the user.

The Graphics

The AR app can get the images frame by frame, using the android.hardware.camera preview callback class. One can also draw over the surface as desired – using the android.hardware.camera object. What is drawn, also depends on the requirements of the application. There are both 2D and 3D graphic APIs available in Android and can be used as desired.

Data Access and Storage

The data of the AR application can be accessed and stored in your own database or locally or online. SQLite database is also useful for quick and easy lookups. The APIs for this can be found in android.database.sqlite. Online methods can also be used for storing and accessing data.
