Abstract
A novel method is presented for enhancing the natural visual perception afforded by
augmented reality (AR) workstations. The approach incorporates a method for simulating perspective
viewing using a monitor-based AR workstation that acts as a window to the physical workspace in
front of it. Although similar AR workstations are often used in industry, they do not provide
natural visual perception. By incorporating user head tracking and a spherical mirror, the method
proposed enhances visual perception by simulating the depth cue of perspective viewing. The method
interactively adjusts the viewing parameters to provide accurate perspective viewing of both the
video stream (representing the physical environment) as well as the virtual objects superimposed
within it. Hence, the user gains the impression of 3D viewing of the entire AR scene when moving
ones head in front of the monitor. This paper describes the hardware setup and the method for
perspective simulation within an AR software application. Finally, an experimental evaluation of
the accuracy of the system is described to demonstrate the feasibility of the approach.
