“VSARD: a low-cost augmented reality system for desktop applications” by Tian and Parkhurst

Augmented Reality (AR) is a quickly developing field in the domain of human computer interaction. The goal of an AR application is to supplement the user’s perception of the real world with synthetic stimuli. For example, in visual AR applications a head-mounted display (HMD) can be used to overlay graphical renderings of virtual objects onto a view of the real world such that both virtual and real objects appear to exist in the same space. With the use of an HMD, the relationship between the user’s head and the image display is fixed and thus the insertion of computer graphics into the scene is straight forward. However, HMDs are limited in a number of important ways, including their high expense and low comfort. An alternative to HMDs for AR applications is to use a desktop display.
