The AR collision is implemented even if the user is not looking directly into the mixed world, but only into the artifact, providing another cognitive possibility as the user can use the tactile to collide.
#Artifact meaning in computer science series#
To make easy the collision actions, we developed series of artifacts, which help the user activity in the active zones, or int the active points by overlapping physical objects with virtual objects. Both approaches still have difficulties in getting collision. Tablets are used in direct view, since the user points the camera to the scene and looks directly into the mixed world.
Monitors are used as an option for indirect view, since the user does not look directly into the mixed world. An additional problem involving HMD is the interaction with the real environment, which places virtual interactive zones to the user, making the collision with these zones hard due to the difficulty to interact with multiple points in different depths.Īlternative approachs to develop ARS involve the use of monitors and tablets. However they lack in several aspects, such as ergonomics, high prices and relatively low mobility due to their sizes and connectivity features. HMDs are currently the dominant display technology in the AR field. Augmented Reality Systems (ARS) standard design.
