Augmented Reality (AR) makes it possible to insert computer generated
information and objects onto a user’s view of the real-world. Optical
See-Through (OST) Head-Mounted Displays (HMDs) are becoming an
increasingly common medium for presenting AR content, with the added
benefit of enabling users to observe the real-world directly, through
transparent display material, alongside computer graphics (CG)
content. A problem in OST HMD systems, though, is the existence of
focal rivalry resulting from the distance disparity between real world
objects and the virtual screen of the HMD. Due to the focal
limitations of the human eye, this focal discrepancy results in the CG
image appearing blurred when real objects are fixated upon. The goal
of our SharpView system is to ameliorate this problem through
sharpening.
SharpView utilizes a variable sharpening filter, based on the eye's
Point Spread Function (PSF), to process the CG imagery before it is
displayed. We derive the PSF from three parameters in real-time: pupil
size, fixation distance, and the focal distance of the virtual display
screen. Our demonstration allows users to experience the focal
disparity problem in OST HMD hardware and view the improved legibility
of CG content provided by the SharpView technique.
