A spectacle-mounted shuttering device, the Portable Liquid-crystal Apparatus for Tachistoscopy via visual Occlusion, based on light-scattering cholesteric liquid crystals, is introduced. Operating characteristics of the device are discussed with respect to the design objectives of comfort, switching speed, light transmission, light extinction, safety, and reliability. A number of practical research, clinical, and industrial applications of the spectacles as tachistoscope, stroboscope, and… Expand
Tachistoscopic software for Macintosh computers
A new soft-ware package that provides tachistoscopic functions for Macintosh computers is described, allowing tachistsoscopic presentation of large or multibit depth images that is not available with alternative methods. Expand
A low-cost visual occlusion device
The response time and transparency of the proposed low-cost visual occlusion device are evaluated; the experiments yielded reasonable results. Expand
The effects of periodic visual occlusion on ball catching.
Generally, catching performance deteriorated as frequency was reduced; performance deteriorated rapidly when this interval was greater than 80 ms; presumably this occurred because subjects had difficulty integrating visual information separated by longer temporal intervals. Expand
Automated vision occlusion-timing instrument for perception–action research
A new laser curtain wireless trigger for vision occlusion spectacles that is portable and fast in terms of its transmission time and improves upon the limitations of existing vision occLusion spectacle triggers, indicating that it is a valuable instrument for perception–action research in a variety of disciplines.

Vergence-accommodation conflict in virtual reality displays induces phoria adaptation
This approach presents a novel method for investigating phoria adaptation with an active stereo setup creating a ‘‘virtual prism’’ instead of the usual optical prisms and investigates the role of VAC inphoria adaptation for crossed as well as uncrossed disparity. Expand
Automated system for ball launching, visual occlusion, and data acquisition in a ball-hitting task
Electromechanical devices, under computer control, for projecting a table-tennis ball, selecting monocular or binocular visual input, and recording ball-hitting performance are described. Expand
Visual transparent & visual occlusion: An EEG and COP study
Electroencephalography (EEG) and centre of pressure (COP) data were recorded in young adults for 60 seconds during standing in visual transparent (VT) and visual occlusion (VO) conditions to understand postural steadiness in VT and VO conditions. Expand
Effects of Stereoscopic and Rotational Displays in a Three-Dimensional Path- Tracing Task
The results indicated that performance improved using either stereoscopic and rotational display techniques relative to viewing two-dimensional (2D) displays, however, rotational displays were superior to stereoscopic displays, and performance was best when both techniques were combined. Expand
Monocular and binocular vision in one-hand ball catching: interocular integration.
Results are discussed both in terms of the sources of visual information useful for the interception of objects and the temporal differences for interocular integration between the perception of form and visual-motor control. Expand
Intermittent Vision and Discrete Manual Aiming
It would appear that brief visual samples of the movement environment are sufficient for reasonably precise closed-loop control. Expand


Alternating-field stereoscopic displays using light-scattering liquid crystal spectacles
Abstract Field-sequential stereoscopy, an increasingly accepted means of displaying three-dimensional visual images, is reviewed. The conventional electrooptic shutter devices used for viewing suchExpand
Stereoscopic viewing with PLZT ceramics
Abstract A new electro-optic shutter viewing device is described for use with stereoscopic real-time television and computer-driven CRT display systems. The high speed electronic shutters employ leadExpand
The pi-Cell: A Fast Liquid-Crystal Optical-Switching Device
Abstract A new approach is given for obtaining fast electro-optical response and good angular-viewing characteristics in a liquid-crystal variable-retardation device. The improved characteristicsExpand
Electro-Optic Shutters and Filters
The applications of liquid crystals in perceptual research are examined.
Comparative evaluation of computer-based tachistoscopes
Various methods of implementing a computer-based tachistoscope are compared, and a system of callable subroutines is favored, together with a file-driven system written in the host language using the subrouted systems. Expand
Investigation of outside visual cues required for low speed and hover
Knowledge of the visual cues required in the performance of stabilized hover in VTOL aircraft is a prerequisite for the development of both cockpit displays and ground-based simulation systems.Expand
Eyestrain and visual display units: a review
Abstract A review is presented of current knowledge about the nature, incidence and causes of eyestrain or visual fatigue among VDU operators. It is suggested that fatigue and discomfort may resultExpand
Exposure and occluded duration effects in a ball-catching skill.
Male Ss from a university population attempted single-handed catches of lawn tennis balls delivered by a mechanical projection machine using a split-plot factorial design, and the most important variable was not VP, but a composite term VP + OP. Expand
Skill level, vision, and proprioception in simple one-hand catching.
The data provide only minimal support for Smyth and Marriott' (1982) contention that limb position is inadequately specified by articular proprioception, but vision appears necessary to control the precise temporal organization of the grasp phase of one-hand catching. Expand
Cholesteric Texture and Phase Change Effects
This paper describes the more useful ways of using thin layers of cholesteric liquid crystals as display devices. There are two metastable configurations of thin layers of cholesterics, the GrandjeanExpand
