Basic Perception in Head-Worn Augmented Reality Displays

Abstract

Head-worn displays have been an integral part of augmented reality since the inception of the field. However, due to numerous difficulties with designing us-ing such unique hardware, the perceptual capabilities of users suffer when looking at either the virtual or real portions of the augmented reality. We discuss the perceptual background and a series of experiments – in the literature and in our laboratories – measuring the degradation of basic functions of the human visual system when us-ing head-worn augmented reality displays. In particular, we look at loss of visual acuity and contrast (and how these in turn affect text legibility), distortion of per-ceived colors, and difficulties of fusing stereo imagery. We discuss the findings and the implications for head-worn display design. Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to a penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number.
