Modern mobile Augmented Reality systems use one or more of the following _____ technologies: digital cameras and/or other optical sensors, accelerometers, GPS, gyroscopes, solid state compasses, RFID and wireless sensors.

A key measure of AR systems is how realistically they ____ augmentations with the real world?

Which is characteristic of AR systems?

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?

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.

Which is NOT correct about Augmented reality ?

_____ provide 512 numerically encoded markers that can be used with any image. Markers may be small and you can detect and track several of them simultaneously?

(...) 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?

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?

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?

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?
