These systems can be used to view local or remote video views of real world scenes, combined with overlaid CG.The viewing of a remote scene is an integral component of telepresence applications.
This system allows the observer to view the real world directly using half-silvered mirrors with CG electronically composited into the image. An advantage id that the real-world can be directly viewed and manipulated.

Most of the medical applications deal with image guided surgery. Pre-operative imaging studies, such as CT or MRI scans, of the patient provide the surgeon with the necessary view of the internal anatomy. From these images the surgery is planned. Visualization of the path through the anatomy to the affected area where, for example, a tumor must be removed is done by first creating a 3D model from the multiple views and slices in the preoperative study. AR can be applied so that the surgical team can see the CT or MRI data correctly registered on the patient in the operation theater while the procedure is progressing. Being able to correctly register the images at the point will enhance the performance of the surgical team and eliminate the need for the painful and cumbersome stereotactic frames currently used for registration.
The military has been using display in cockpits that present information to the pilot on the windshield of the cockpit or the visor of their flight helmet. This is a form fo AR display.
The scenario for this application consists of an office manager who is working with an interior designer on the layout of a room. The office manager intends to order furniture for the room. On a computer monitor the pair see a picture of the room from the viewpoint of the camera. By interacting with various manufacturers over a network, they select furniture by querying databases using a graphical paradigm. The system provides descriptions and pictures of furniture that is available from the various manufactures who have made models available in their databases. Pieces or groups of furniture that meet certain requirements such as colour, manufacturer, or price may be requested. The users choose pieces from this "electronic catalogue" and 3D renderings of this furniture appear on the monitor along with the view of the room. The furniture is positioned using a 3D mouse. Furniture can be deleted, added, and rearranged until the users are satisfied with the result; they view these pieces on the monitor as they would appear in the actual room. As they move the camera they can see the furnished room from different points of view.
