The source code for this project is hosted on _____ and the compiled SDKs for all platforms (Mac OS X, PC, Linux, Android, iOS), along with the ARToolKit plug-in for Unity3D?

The __ is the mandatory blank area that appears adjacent to the border along its entire length. The can be either inside or outside of the border and is required in order to guarantee there is enough contrast for the algorithm to detect the Contour?

Vuforia, as well as other AR software kits, supports the tracking of multiple targets simultaneously.Which of the following is NOT a factor that impacts the maximum number of targets that can be tracked at the same time?

One of the most difficult parts of developing an augmented reality application is precisely calculating the user's viewpoint in real time so that the virtual images are exactly aligned with real world objects. ARToolKit uses computer vision techniques to calculate the real camera position and orientation relative to square shapes or flat textured surfaces, allowing the programmer to overlay virtual objects. ARToolKit currently do NOT support?

There are key optical variables (for camera hardware) of interest to AR SDK (like ARToolKit). Which of the following is NOT an important camera characteristic?

(...) are stored on the device with your app. You can load and unload (...) programmatically, and activate or deactivate them using the ObjectTracker API. Activating a loaded database enables Vuforia to detect any of the targets included in that database. The number of targets that can be active simultaneously, across one or more loaded (...), is constrained by the device context and its available resources?

Which statement is correct for Augmented Reality?

Which is NOT correct about Augmented reality ?

A (...) is a display device paired to the forehead such as a harness or helmet. (...) places images of both the physical world and virtual objects over the user's field of view. Modern (...) often employ sensors for six degrees of freedom monitoring that allow the system to align virtual information to the physical world and adjust accordingly with the user's head movements.

In the ARToolKit software, default camera properties are contained in the camera parameter file camera_para.dat, that is read each time an application is started?

Which is characteristic of AR systems?
