Augmented Reality in Android with Google’s Face API

Jul 17, 2017 | 4 Minutes Read

What's Inside

Augmented Reality (AR) is about draping pieces of a virtual world over the real world. It is in contrast to Virtual Reality (VR) which is about replacing the real world with a virtual one. This is very helpful in Android mobile app development. This Augmented Reality on mobile devices is this simply means enhancing what you can see through the device’s camera with multimedia content. For example, you can point your phone camera at a movie poster. And watch its trailer, or you can move at a start in the sky and know its name. So, the question arises where to display, what and how to display it.

The ‘where’ might involve areas like 2-D image matching and tracking. It also includes 3-D matching and tracking, location tracking and SLAM tracking. It uses GPS, compass, accelerometer, gyroscope. Sometimes, it is nothing more than some predefined point locations, often referred as Point of Interest (POIs).

Then again, the what and the by what method may use 3-D display rendering, animations, and gesture detection. All in all, the what can be any bit of advanced data (e.g. content, picture, video) that the client may likewise be able to connect with (e.g. turn or move it).

What can Google’s Face API do?

Google’s Face API performs confront detection, which locates in pictures, alongside their position (where they are in the photo) and introduction (which way they’re confronting, in respect to the camera). It can recognize landmarks (points of interest on a face) and perform arrangements to decide if the eyes are open or shut, and regardless of whether a face is grinning. The Face API additionally recognizes and takes after countenances in moving pictures, which is known as face tracking.

The Face API doesn’t perform face recognition, which associates a given face to a personality. It can’t play out that Facebook trap of distinguishing a face in a picture and after that recognizing that individual.

Once you’re ready to distinguish a face, its position and its points in a picture, you can utilize that information to augment the picture with your own particular reality! Applications like Pokemon GO or Snapchat make utilization of expanded reality to give clients a fun approach to utilize their cameras, thus can you!

Let us now introduce five of the various AR instruments that exist right now and that you can utilize it to develop apps for smartphones, tablets or even smart-glasses. The accompanying table contains data about the license(s), under which every one of these tools is conveyed, and the stages that it supports.


Picture (multi-)recognition and (multi-)following, 3-D protest rendering continuously, and additionally client cooperation with 3-D objects (e.g. determination, turn, scaling) are a portion of the components that ARPA SDK offers for building AR applications on iOS and Android. ARPA GPS SDK supplements ARPA SDK with geolocation-based AR usefulness: it enables you to characterize your own particular POIs that, when recognized, the client can choose them and get more data about them or even perform activities on them (e.g. the “take-me-there” activity that shows a guide with headings to the chose POI).

ARPA GLASS SDK and ARPA Unity Plugin offer comparative usefulness with ARPA SDK for Google Glass and the Unity diversion motor, individually. It is important that Arpa Solutions, the organization behind these SDKs, have throughout the years built up their own AR stage. A portion of the components of which (e.g. confront acknowledgment and virtual catches) may eventually exchange likewise to the SDKs.


With AR Browser SDK you can include and remove POIs freely from the scene continuously, connect with them. E.g. touch them or indicate the camera them. It performs activities on them (e.g. send SMS or offer on Facebook). Picture Matching SDK enables you to make your own particular nearby coordinating pool with a great many pictures (stacked both from neighborhood assets and remote URLs). It utilizes to coordinate any picture with no association with the web. While it additionally bolsters QR code and scanner tag acknowledgment. Aside from these two SDKs, ARLab will soon dispatch Object Tracking, Image Tracking, and Virtual Button SDKs. All SDKs are accessible for both Android and iOS.


DroidAR is an open-source structure that adds area based AR usefulness to Android applications. Motion (e.g. full turn) location, bolster for static and enlivened 3-D objects (utilizing the model loaders from the libGDX game development framework). The client can cooperate with (e.g. tap on them), and marker discovery is a piece of the usefulness. DroidAR offers and that is just shaded by the poor documentation that exists for the venture. There is a segment of the venture README record on GitHub that gives a review of a shut source variant of DroidAR, DroidAR 2, which appears to make them intrigue upgrades contrasted with its open-source partner (e.g. Hammer following and a jMonkeyEngine module).


Multi-target recognition, target following, virtual buttons, Smart TerrainTM, and Extended Tracking are a portion of the elements of Vuforia SDK. Vuforia bolsters the recognition of a few sorts of targets (e.g. objects, pictures, English content). Particularly for picture acknowledgment purposes, Vuforia permits applications to utilize databases that are either neighborhood on the gadget or in the Cloud. The stage is accessible for Android, iOS, and Unity. There is likewise an adaptation of the SDK for brilliant glasses. Specifically Epson Moverio BT-200, Samsung GearVR, and ODG R-6 and R-7. It is as of now moving to its beta stage. It is open for early get to applications from qualified designers.

Metaio SDK

Metaio SDK supports among others 2-D picture, 3-D protest, face, SLAM and area following. It’s a standardized identification and QR code examining, persistent visual pursuit (both disconnected and online through Metaio CVS), and signal discovery. It has likewise outlined their own AR scripting dialect. AREL (Augmented Reality Experience Language) that enables you to build up your AR applications utilizing normal web advances (HTML5, XML, Javascript). Send them all over the place. You can utilize Metaio SDK to create AR applications for Android, Windows PC,  iOS, Epson Moverio BT-200 and Vuzix M-100, Google Glass, or utilizing Unity.
