Vuforia

Vuforia is a cross-platform Augmented Reality (AR) and Mixed Reality (MR) application development platform, with robust tracking and performance on a variety of hardware (including mobile devices and mixed reality Head Mounted Displays (HMD) such as the Microsoft HoloLens). Unity’s integration of Vuforia allows you to create vision apps and games for Android and iOSApple’s mobile operating system. More info

using a drag-and-drop authoring workflow. A Vuforia AR+VR samples package is available on the Unity Asset StoreA growing library of free and commercial assets created by Unity and members of the community. Offers a wide variety of assets, from textures, models and animations to whole project examples, tutorials and Editor extensions. More info

, with several useful examples demonstrating the most important features of the platform.

Vuforia supports many third-party devices (such as AR/MR glasses), and VR devices with back-facing camerasA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info

(such as the Gear VR). See the Vuforia page on Devices for a full list of supported devices. See the Vuforia API reference for more information about classes, properties and functions used in the SDK.

You can use any device with a camera to test ARAugmented Reality (AR) uses computer graphics or video composited on top of a live video feed to augment the view and create interaction with real and virtual objects.

Important concepts

Before learning more about Vuforia and its supported features, you need to understand a number of important concepts. Among these concepts are forms of tracking and marker types commonly used in Vuforia applications.

Marker-based tracking

In AR or MR, markers are images or objects registered with the application which act as information triggers in your application. When your device’s camera recognizes these markers in the real world (while running an AR or MR application), this triggers the display of virtual content over the world position of the marker in the camera view. Marker-based tracking can use a variety of different marker types, including QR codes, physical reflective markers, Image Targets and 2D tags. The simplest and most common type of marker in game applications is an Image Target.

Common Image Target types

Image Targets

Image Targets are a specific type of marker used in Marker-based tracking. They are images you manually register with the application, and act as triggers that display virtual content. For Image Targets, use images containing distinct shapes with complex outlines. This makes it easier for image recognition and tracking algorithms to recognize them.

Markerless tracking

Applications using Markerless tracking are more commonly location-based or position-based Augmented or Mixed Reality. This form of tracking relies on technologies such as GPS, accelerometer, gyroscope and more complex image processing algorithms, to place virtual objects or information in the environment. The VR hardware and software then treats these objects as if they are anchored or connected to specific real-world locations or objects.
