Overview According to Wikipedia , ARCore is a software development kit developed by Google that allows for augmented reality applications to be built. ARCore uses three key technologies to integrate virtual content with the real environment: Motion Tracking: it allows the phone to understand its position relative to the world.

Environmental understanding: This allows the phone to detect the size and location of all type of surfaces, vertical, horizontal and angled. Create a new Android Studio project and select an empty activity. Add the following dependency to your project level build. Compatibility Check This is all that you need to do in the layout file. Adding the assets You will need to add the 3D models which will be rendered on your screen. When you download the zip file from poly, you will most probably find 3 files. Building the Model Add the following code to your MainActivity. Adding the Model to Scene The arFragment hosts our scene and will receive the tap events. Add the following code to onCreate method: arFragment.

Scene : This is the place where all your 3D objects will be rendered. This scene is hosted by the AR Fragment which we included in the layout. An anchor node is attached to this screen which acts as the root of the tree and all the other objects are rendered as its objects. HitResult : This is an imaginary line or a ray coming from infinity which gives the point of intersection of itself with a real-world object.

Anchor : An anchor is a fixed location and orientation in the real world. It can be understood as the x,y,z coordinate in the 3D space. Pose is the position and orientation of the object in the scene. You may be prompted to install or update Google Play Services for AR if it is missing or out of date. Object placement is refined in real time as the user moves further around the environment. Once ARCore detects the correct pose in the region where the AR object is placed, the white object automatically updates to be pose-accurate, and becomes opaque. Tap the gear icon on the screen and choose Instant Placement in the drop-down menu. The Enable Instant Placement checkbox should already be selected. Tap on the screen to place an object. Make sure to continue moving the device around after seeing the holographic object appear on screen, so that ARCore can get sufficient data about your surroundings to accurately anchor the virtual object.

simultaneously show the real and virtual worlds. The system was rigidly mounted on the ceiling and used some CRT screens and a transparent display to be able to create the sensation of visually merging the real and virtual.

Since then, we have seen different trends in AR display, going from static to wearable and handheld displays. One of the major trends is the usage of optical see-through OST technology. The idea is to still see the real world through a semi-transparent screen and project some virtual content on the screen. The merging of the real and virtual worlds does not happen on the computer screen, but directly on the retina of your eye, as depicted in the following figure:. You can imagine perceiving the world not directly, but through a video on a monitor.

The video image is mixed with some virtual content as you will see in a movie and sent back to some standard display, such as your desktop screen, your mobile phone, or the upcoming generation of head-mounted displays as shown in the following figure:. In this book, we will work on Android-driven mobile phones and, therefore, discuss only VST systems; the video camera used will be the one on the back of your phone. With a display OST or VST in your hands, you are already able to superimpose things from your real world, as you will see in TV advertisements with text banners at the bottom of the screen. However, any virtual content such as text or images will remain fixed in its position on the screen. The superposition being really static, your AR display will act as a head-up display HUD , but won't really be an AR as shown in the following figure:.

Google Glass is an example of an HUD. While it uses a semitransparent screen like an OST, the digital content remains in a static position. AR needs to know more about real and virtual content. It needs to know where things are in space registration and follow where they are moving tracking. Registration is basically the idea of aligning virtual and real content in the same space. If you are into movies or sports, you will notice that 2D or 3D graphics are superimposed onto scenes of the physical world quite often. In ice hockey, the puck is often highlighted with a colored trail.

However, AR differs from those effects as it is based on all of the following aspects proposed by Ronald T. Azuma in :.

It's in 3D : In the olden days, some of the movies were edited manually to merge virtual visual effects with real content. A well-known example is Star Wars, where all the lightsaber effects have been painted by hand by hundreds of artists and, thus, frame by frame. Nowadays, more complex techniques support merging digital 3D content such as characters or cars with the video image and is called match moving. AR is inherently always doing that in a 3D space.

The registration happens in real time : In a movie, everything is pre-recorded and generated in a studio; you just play the media. In AR, everything is in real time, so your application needs to merge, at each instance, reality and virtuality. It's interactive : In a movie, you only look passively at the scene from where it has been shot. In AR, you can actively move around, forward, and backward and turn your AR display—you will still see an alignment between both worlds. Building a rich AR application needs interaction between environments; otherwise you end up with pretty, 3D graphics that can turn boring quite fast. AR interaction refers to selecting and manipulating digital and physical objects and navigating in the augmented scene. Rich AR applications allow you to use objects which can be on your table, to move some virtual characters, use your hands to select some floating virtual objects while walking on the street, or speak to a virtual agent appearing on your watch to arrange a meeting later in the day.

We will look at how some of the standard mobile interaction techniques can also be applied to AR. We will also dig into specific techniques involving the manipulation of the real world. Previously in this chapter, we discussed what AR is and elaborated on display, registration, and interaction. As some of the notions in this book can also be applied to any AR development, we will specifically look at mobile AR. Mobile AR sometimes refers to any transportable, wearable AR system that can be used indoors and outdoors.

In this book, we will look at mobile AR with the most popular connotation used today—using handheld mobile devices, such as smartphones or tablets. With the current generation of smartphones, two major approaches to the AR system can be realized. These systems are characterized by their specific registration techniques and, also, their interaction range. They both enable a different range of applications. The systems, sensor- based AR and computer vision-based AR, are using the video see-through display, relying on the camera and screen of the mobile phone.

Sensor-based AR uses the location sensor from a mobile as well as the orientation sensor. Combining both the location and orientation sensors delivers the global position of the user in the physical world. There are several possible orientation sensors available on handheld devices, such as accelerometers, magnetometers, and gyroscopes. The measured position and orientation of your handheld device provides tracking information, which is used for registering virtual objects on the physical scene. The position reported by the GPS module can be both inaccurate and updated slower than you move around. This can result in a lag, that is, when you do a fast movement, virtual elements seem to float behind. One of the most popular types of AR applications with sensor-based systems are AR browsers, which visualize Points of Interests POIs , that is, simple graphical information about things around you.

If you try some of the most popular products such as Junaio, Layar, or Wikitude, you will probably observe this effect of lag. The advantage of this technique is that the sensor-based ARs are working on a general scale around the world, in practically any physical outdoor position such as if you are in the middle of the desert or in a city. One of the limitations of such systems is their inability to work inside or work poorly or in any occluded area no line-of-sight with the sky, such as in forests or on streets with high buildings all around.

The other popular type of AR system is computer vision-based AR. The idea here is to leverage the power of the inbuilt camera for more than capturing and displaying the physical world as done in sensor-based AR. This technology generally operates with image processing and computer vision algorithms that analyze the image to detect any object visible from the camera. This analysis can provide information about the position of different objects and, therefore, the user more about that in Chapter 5 , Same as Hollywood — Virtual on Physical Objects. The advantage is that things seem to be perfectly aligned. The current technology allows you to recognize different types of planar pictorial content, such as a specifically designed marker marker-based tracking or more natural content markerless tracking.

One of the disadvantages is that vision-based AR is heavy in processing and can drain the battery really rapidly. Recent generations of

smartphones are more adapted to handle this type of problem, being that they are optimized for energy consumption. So let's explore how we can support the development of the previously described concepts and the two general AR systems. As in the development of any other application, some well-known concepts of software engineering can be applied in developing an AR application.

We will look at the structural aspect of an AR application software components followed by the behavioral aspect control flow. The application layer corresponds to the domain logic of your application. If you want to develop an AR game, anything related to managing the game assets characters, scenes, objects or the game logic will be implemented in this specific layer.

This method checks whether your device can support Sceneform SDK or not. If a device does not support these two, the Scene would not be rendered and your application will show a blank screen. Now with the device compatibility check complete, we shall build our 3D model and attach it to the scene. You will need to add the 3D models which will be rendered on your screen. Now you can build these models yourself if you are familiar with 3D model creation. Or, you can visit Poly. They are free to download.

Just credit the creator and you are good to go. In the Android Studio, expand your app folder available on the left-hand side project pane. This folder will hold all of your 3D model assets. Create a folder for your model inside the sample data folder. Most important of these 3 is the. It is your actual model. Now right click on the. The first option would be to Import Sceneform Asset. Click on it, do not change the default settings, just click finish on the next window. Your gradle will sync to include the asset in the assets folder.

Once the gradle build finishes, you are good to go. Add the following code to your MainActivity. First , we find the arFragment that we included in the layout file. This fragment is responsible for hosting the scene. You can think of it as the container of our scene. Next , we are using the

decide whether user data will be stored locally or in the cloud. This decision is mostly driven by the number of markers you are going to create. If you are planning to add a large number of markers to your app, consider storing all this data in the cloud, otherwise your app will use much storage on the device. Furthermore, having an idea of the number of markers your app uses also matters because some augmented reality SDKs support a hundred markers while others support thousands.

On the other hand, storing markers locally i. If you are going to create a location-based AR application, geolocation is a fundamental feature that must be supported by the AR tool you are going to use. GPS can be used both in AR games like Pokemon Go as well as in apps made to overlay data on some nearby locations for example to find the nearest restaurant. It is an algorithm that maps the environment where the user is located and tracks all of their movements. AR apps containing this feature can remember the position of physical objects within some environment and position virtual objects accordingly to their position and users movements. The main advantage of this technology is the ability to be used indoors while GPS is only available outdoors. Once you know all the features you could possibly require of an SDK to create your augmented reality app, you can check out the following list of six popular tools that are available on the market.

We consider these toolkits to be the most relevant and appropriate based on the set of features they provide and their value for money. Some of them are free. Vuforia is a leading portal for augmented reality application development that has a broad set of features. Vuforia augmented reality SDK:. ARToolKit is an open-source tool to create augmented reality applications. Even though it's a free library, it provides a rather rich set of features for tracking, including:. With two millions Android active users, Google could not miss the chance to give developers an opportunity to create AR apps on this operating system. Here is the list of features of the 3D SDK:. Wikitude has recently introduced its SDK7, including support for simultaneous localization and Mapping. The tool provides currently the following features:. We decided to organize the main characteristics and features of the mentioned AR tools in one table so that you can quickly compare them.

Needless to say, augmented reality technology is trendy. Each new AR app launch causes waves of excitement. Therefore, savvy developers are trying to master this technology and launch their own AR apps. Now, developers have a wide choice of AR toolkits to create both marker-based and location-based apps. The first step to get started is picking up the augmented reality SDK most suited to comply with their requirements. This article makes it easy to compare features such as image and 3D recognition, storage possibilities, Unity and SLAM support, etc.

Augmented Reality for Android Application Development by. Book description As an Android developer, including Augmented Reality AR in your mobile apps could be a profitable new string to your bow. To be able to create sophisticated AR applications, one has to understand what Augmented Reality truly is. In this chapter, we will guide you toward a better understanding of AR.

We will describe some of the major concepts of AR. We will then move on from these examples to the foundational software components for AR.

Finally, we will introduce the development tools that we will use throughout this book, which will support our journey into creating productive and modular AR software architecture. Ready to change your reality for Augmented Reality? Let's start. As AR has become increasingly popular in the media over the last few years, unfortunately, several distorted notions of Augmented Reality have evolved. Anything that is somehow related to the real world and involves some computing, such as standing in front of a shop and watching 3D models wear the latest fashions, has become AR.

Augmented Reality emerged from research labs a few decades ago and different definitions of AR have been produced. As more and more research fields for example, computer vision, computer graphics, human-computer interaction, medicine, humanities, and art have investigated AR as a technology, application, or concept, multiple overlapping definitions now exist for AR.

Rather than providing you with an exhaustive list of definitions, we will present some major concepts present in any AR application. The term Augmented Reality itself contains the notion of reality. Augmenting generally refers to the aspect of influencing one of your human sensory systems, such as vision or hearing, with additional information. This information is generally defined as digital or virtual and will be produced by a computer.

The technology currently uses displays to overlay and merge the physical information with the digital information.

To augment your hearing, modified headphones or earphones equipped with microphones are able to mix sound from your surroundings in real-

time with sound generated by your computer. In this book, we will mainly look at visual augmentation. The TV screen at home is the ideal device to perceive virtual content, streamed from broadcasts or played from your DVD. Unfortunately, most common TV screens are not able to capture the real world and augment it. An Augmented Reality display needs to simultaneously show the real and virtual worlds.
