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?

_____ 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?

Which is types of HMDS?

AR blends live and digital images in real time, using a and a screen?

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?

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

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.

Which is component of an AR System?
