How to Create a React Native Augmented Reality App

The phrase “augmented reality” refers to the functionality of applications that collect sensory input and supplement it with specific functional information. The data is collected using sensors that are already built into mobile devices, including the camera, GPS, accelerometer, and others on react native mobile apps. These days, several professional institutions as well as the fields of education and science actively use such applications. According to Statista, in 2023, the AR & VR industry is anticipated to generate US$31.12 billion in revenue.

What distinguishes virtual reality from augmented reality? Virtual reality’s internal workings are more intricate. It totally swaps out elements that users can see for those that have been predefined by the script of the application. Usually, additional equipment that would heighten immersion is needed for this operation (e.g. a virtual reality headset). Applications based on the idea of augmented reality, on the other hand, can easily use the screen of a mobile device to provide the user the right experience.

How Do Applications For Augmented Reality Function?

The detection of markers and the transformation of data obtained through GPS and other built-in sensors are the two fundamental guiding principles of augmented reality programming apps. Below is a detailed review of the workings of these two AR applications.

The use of markers

Such programs operate on the basis of the juxtaposition of built-in markers and data obtained from a user’s smartphone or tablet camera. Both extremely simple objects (like UPCs and QR codes) and extremely complex objects (like color shades and people’s faces) can serve as markers. What happens if markers are found to match? The AR program in this instance runs a specific script (for instance, it “draws” brand-new geographic objects over the surrounding area, much like the well-known mobile video game Pokémon Go).

The Use of GPS

The use of information obtained from GPS indications, gyroscopes, accelerometers, etc. Information requested by the user is displayed on the gadget’s screen after processing data from the device’s internal sensors.

We have a basic understanding of how data recognition works in AR applications; let’s move on to selecting the toolkit that is specifically designed for their development. Below, we’ve provided a list of popular frameworks that are frequently utilized while creating augmented reality.

The Creation of Augmented Reality Applications Goes Through Four Key Stages

• Deciding On the Structure

You must select if an application will be native (i.e., dedicated to a single platform) or cross-platform before deciding on the ideal framework for its development based on the concept of augmented reality. The latter method has proven popular with clients recently due to its reasonable time and budgetary needs, as seen by practice.

Many well-known cross-platform frameworks exist. Among these are Appcelerator Titanium, React Native (which integrates JavaScript), Iconic Framework, and PhoneGap or Apache Cordova for bridging (also works with JavaScript). For the Android and iOS platforms, developers most frequently employ these options to create augmented reality.

• Linking the Necessary Libraries

Let’s say we opt for a development environment. Although all of the aforementioned frameworks are excellent choices for creating AR applications, React Native mobile apps for cross-platform development won our challenge with the highest score. There are specific libraries that operate on the marker recognition principle, and JavaScript contains a few of them. These libraries are supplementary tools that enable AR application functioning. Despite the fact that some developers create their own libraries for turnkey AR applications, the majority of developers tend to use two well-established libraries.

The Following Procedures Make Up the Library’ Guiding Principle

Each frame records a continuous stream of camera images. After that, the received data is examined in relation to the pre-set markers. The program receives information on the positions of each marker in a frame as a result of that analysis (particularly, its turn and location). What occurs to that information? The program uses it to render 3D models over the actual image that was taken with the user device’s camera.

There are a few variations between the libraries. In JSARToolKit, users can set their own custom image dimensions. The tiniest of them are processed the fastest, but because of how little they are, the recognition process may not be adequately precise.

Recently, JavaScript Unveiled an Online Repository for Open-Sourced AR.Js Code

As well as offering animation at a frame rate of 60FPS, it has the ability to simultaneously recognize several markers. It was initially quite helpful if you were creating Android augmented reality programming applications. All platforms currently support AR.js. It is necessary to take into account a number of improvements unique to AR.js and not available in the first two frameworks. This includes the capacity to construct transparent (glassy surface effect) 3D objects, as well as openings in walls and portals to other dimensions, and a more “lively” display of shades.

Arranging the fundamental features of the AR application. You will have to work through a collection of essentially crucial components to develop an application based on augmented reality technology and guarantee it meets the predicted requirements;

• Animation

React Native Animatable is actively used by developers for building AR applications using the React Native framework. This gives the design a more lively and user-friendly feel. Additionally, due to the use of Animated API components, React Native uses an animation technique that is primarily distinct from CSS. Lagging when stress loads is not included in this function. Furthermore, React Native Sound, which is devoted to sound clip production, can be enabled in order to get a full-fledged user experience.

• Scanning an Image

With the help of the specialized React Native Camera module, scanning of anything captured by a mobile device’s camera (including UPC codes, videos, and images) may be accomplished. This tool is still being developed today.

• Recognizing a Location

A wrapper for the React Native accelerometer, gyroscope, and magnetometer is React Native Motion Manager. When building location-based augmented reality applications, these technologies can be incredibly helpful.

• User Engagement

PanResponder web API is used by React Native to communicate with user gestures. It offers complete touch recognition and safeguards against unwanted gestures. This tool can be particularly helpful for creating entertainment-related applications where users can issue various touch-based commands.

• Applying For Testing

According on the collective experience of many developers, your program may occasionally fail to recognize certain photos, locations, or surfaces. Each and every factor affecting the “readability” of streamed video must be taken into account while evaluating the developed software solution. It’s crucial to take into account factors like lighting or the existence of different foreground items that impede the spotlight. Consider a plan for data backup as well. In the event of a GPS or internet connection failure, this method will enable you to save the data you have already received.

Conclusion

For many reasons, using Native React when creating an augmented reality project is a smart decision. Despite the fact that this may be your first experience in this field, you won’t encounter any problems. On the contrary, it might give you the self-assurance you need to explore this universe.

Due to the availability of ReactJS binding, hot-reloading, and clear documentation, the developer experience is rich. Nevertheless, because the React-Native JavaScript thread can cause event congestion and lags, we don’t advise using it for complicated or performance-based apps. So, in the event that performance is important, we would advise full-native alternatives.
