A haploscope is an optical system which produces a carefully controlled
virtual image. Since the development of Wheatstone's original stereoscope in
1838, haploscopes have been used to measure perceptual properties of human
stereoscopic vision. This paper presents an augmented reality (AR) haploscope,
which allows the viewing of virtual objects superimposed against the real
world. Our lab has used generations of this device to make a careful series of
perceptual measurements of AR phenomena, which have been described in
publications over the previous 8 years. This paper systematically describes the
design, assembly, calibration, and measurement of our AR haploscope. These
methods have been developed and improved in our lab over the past 10 years.
Despite the fact that 180 years have elapsed since the original report of
Wheatstone's stereoscope, we have not previously found a paper that describes
these kinds of details.Comment: Accepted and presented at the IEEE VR 2018 Workshop on Perceptual and
