In optical see-through augmented reality (AR), information is often distributed between real and virtual contexts, appears at different distances from the user. To integrate information, users must repeatedly switch context change focal distance. If user's task conducted under time pressure, they may attempt to while their eye still changing distance, a phenomenon we term <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">transient blur</i> ....

For optical see-through augmented reality (AR), a new method for measuring the perceived three-dimensional location of virtual objects is presented, where participants verbally report object's relative to both vertical and horizontal grid.

In augmented reality (AR) environments, information is often distributed between real and virtual contexts, appears at different distances from the user. Therefore, to integrate information, users must repeatedly switch context refocus eyes. Previously, Gabbard, Mehra, Swan (2018) examined these issues, using a text-based visual search task monocular optical see-through AR display. this work, authors report replication of earlier experiment, custom-built haploscope. The successful...

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 human stereoscopic vision. This paper presents augmented reality (AR) haploscope, allows viewing objects superimposed against real world. Our lab has generations this device make careful series measurements AR phenomena, described publications over previous 8 years. systematically...

For optical see-through head-mounted displays, the mismatch between a display's focal length and real world scene inadvertently prevents users from simultaneously focusing on presented virtual content scene. It has been shown that it is possible to ameliorate out-of-focus blur for images with known focus distance, by applying an algorithm called Sharp View. However, remains unclear if View also improves readability clarity of text rendered display. In this study, we investigate whether...

For optical, see-through augmented reality (AR), a new method for measuring the perceived three-dimensional location of small virtual object is presented, where participants verbally report object's relative to both horizontal and vertical grid. The tested with Microsoft HoloLens AR display, examines two different designs, whether turning in circle between reported locations disrupts tracking, accuracy errors found display might be due systematic that are restricted particular display....

Abstract Background Molecular recognition in proteins occurs due to appropriate arrangements of physical, chemical, and geometric properties an atomic surface. Similar surface regions should create similar binding interfaces. Effective methods for comparing can be used identifying regions, predict interactions without regard the underlying structural scaffold that creates Results We present a new descriptor protein functional surfaces algorithms using these descriptors compare identify...

In previous papers, a novel haploscope-based AR environment was implemented [1, 3]. that system, participant looks through set of reflective lenses onto real-world environment. However, at the same time, there are monitors to side displaying virtual object. This object is reflected and thus, from viewpoint participant, overlaid real Hua [1], some initial work done designing calibration procedure for this The current seeks modify expand Hua's original make it both more effective efficient. As...

Usable x-ray vision has long been a goal in augmented reality research and development. X-ray vision, or the ability to view understand information presented through an opaque barrier, would be imminently useful across variety of domains. Unfortunately, however, effect on situation awareness, operator's understanding task environment, not significantly studied. This is important question; if does increase what use it? Thus, we have developed system, order investigate awareness context action...

Most augmented reality (AR) research is performed with commercially-available displays. However, these displays have unadjustable mechanical and optical properties, which limit the experimental questions that can be asked. In order to ask certain questions, it becomes necessary build a custom display, using off-the-shelf components. field of visual perception, such devices are often developed, called haploscopes. this paper, we describe design an AR haploscope, present virtual objects seen...

Accurate and usable x-ray vision is a significant goal in augmented reality (AR) development. X-ray vision, or the ability to comprehend location object information when it presented through an opaque barrier, needs successfully convey scene be viable use case for AR. Further, this investigation should performed ecologically valid context order best test vision. This research seeks experimentally evaluate perceived of stimuli with as compared real-world window, at action space distances 1.5...

Many augmented reality (AR) applications require observers to shift their gaze between AR and real-world content. To date, commercial optical see-through (OST) displays have presented content at either a single focal distance, or small number of fixed distances. Meanwhile, stimuli can occur variety Therefore, when shifting content, in order view new sharp focus, must often change eye's accommodative state. When performed repetitively, this negatively affect task performance eye fatigue....

An important research question in optical see-through (OST) augmented reality (AR) is, how accurately and precisely can a virtual object's real world location be perceived? Previously, method was developed to measure the perceived three-dimensional of objects OST AR. In this research, replication study is reported, which examined whether are biased direction dominant eye. The successful analysis suggests that perceptual accuracy not Compared previous study's findings, overall increased,...

Triangulation by walking is a method that has been used to measure perceived distance, where observers walk triangular path. This at action space distances of approximately 1.5 30 meters. In this work, conceptual replication these triangulation methods are discussed and evaluated for use in measuring the distance an object seen through window set into wall. The motivation work study how operates when augmented reality (AR) visualize objects located behind opaque surfaces, AR application...
