AUGMENTED REALITY
(Augmented Physical Reality)
A BASIC EXAMPLE
In this application, an Augmented Reality space is developed.
A physical and a virtual space which are being connected in real time. The virtual element is an imaginary archaeological finding - a statue. This virtual element is being continuously repositioning and reorientating itself, with the help of a physical marker printed on common paper (using optical tracking). The physical space is my My_MR_Lab, which I capture with a webcam. The streaming video of the physical space is being integrated in real time with the virtual world. Besides, this is the main difference between Virtual Reality and multimedia which only offer prerecorded data and therefore certain types of interaction.
In this example, we see the video capture of my PC screen, on which there is a projection of the webcam capture, in which the virtual space is being intergrated, repositioning and reorientating itself in real time. Annotation (e.g. a yellow pointer) as well as various infomation (e.g. a black circle) concerning certain regions on the virtual statue is also being dynamically displayed.

In this Augmented Reality space there are two 3-Dimensional virtual models, a virtual bicycle and an animated virtual airplane. In addition there is streaming video from a classic platform video game. These virtual elements are dynamically integrated in a physical space, placed on a physical table where I reposition them. |
In this Augmented Reality space I have a 3-Dimensional virtual Antikythera Mechanism reconstruction on my hands. While I study the mechanism, I rotate and translate it in the physical space. About my work on Antikythera Mechanism in Mixed Reality spaces, see The Antikythera Mechanism studied in Mixed Reality spaces. |
