Stereoscopic Displays: Factors Affecting Realism

This paper presents the final outcome of the Final Year Project entitled Stereoscopic Displays: Factors Affecting Realism. The term "Stereoscopic Displays" refers to the stereoscopic technology that is being used in Virtual Reality in order to project a realistic image. The aim of the study is to find out the factors that affect the realism of the projected image in stereoscopic displays as well as to identify image parameter that gives the most impact to user's depth perception of a 3D scene. The study is done by undertaking intensive research from previous literatures, and then carrying out an experiment to determine the parameters that gives the most impact to the depth perception of user. By knowing which parameters that affects the depth perception the most, it can be useful in designing an application that will project a quality 3D image, which will therefore increase the realism effect and then also increases the sense of presence in the users. The research has found out that the factor that affects the realism revolves around on the technical and the human issues. The experiment have been focusing on the testing of 4 parameters, which are motion cues, number of edges on objects, background brightness and distances of objects from the user. From there it has been proven that motion cues, background brightness and distances of objects from user have a positive impact on the depth perception, while the number of edges on the objects is proven to have an impact, but the extent of its effect is inconclusive. As a conclusion to the study, the author believes that this study is only complete at a preliminary level, and still needs continuation to further support the findings that have been made

Engineering data compendium. Human perception and performance. User's guide

The concept underlying the Engineering Data Compendium was the product of a research and development program (Integrated Perceptual Information for Designers project) aimed at facilitating the application of basic research findings in human performance to the design and military crew systems. The principal objective was to develop a workable strategy for: (1) identifying and distilling information of potential value to system design from the existing research literature, and (2) presenting this technical information in a way that would aid its accessibility, interpretability, and applicability by systems designers. The present four volumes of the Engineering Data Compendium represent the first implementation of this strategy. This is the first volume, the User's Guide, containing a description of the program and instructions for its use

Analysis and Selection of a Remote Docking Simulation Visual Display System

The development of a remote docking simulation visual display system is examined. Video system and operator performance are discussed as well as operator command and control requirements and a design analysis of the reconfigurable work station

Trail Making Test performance contributes to subjective judgment of visual efficiency in older adults

Introduction: The determinant factors that influence self-reported quality of vision have yet to be fully elucidated. This study evaluated a range of contextual information, established psychophysical tests, and in particular, a series of cognitive tests as potentially novel determinant factors.   Materials & Methods: Community dwelling adults (aged 50+) recruited to Wave 1 of The Irish Longitudinal Study on Ageing, excluding those registered blind, participated in this study (N = 5,021). Self-reports of vision were analysed in relation to visual acuity and contrast sensitivity, ocular pathology, visual (Choice Response Time task; Trail Making Test) and global cognition. Contextual factors such as having visited an optometrist and wearing glasses were also considered. Ordinal logistic regression was used to determine univariate and multivariate associations.   Results and Discussion: Poor Trail Making Test performance (Odds ratio, OR = 1.36), visual acuity (OR = 1.72) and ocular pathology (OR = 2.25) were determinant factors for poor versus excellent vision in self-reports. Education, wealth, age, depressive symptoms and general cognitive fitness also contributed to determining self-reported vision.   Conclusions: Trail Making Test contribution to self-reports may capture higher level visual processing and should be considered when using self-reports to assess vision and its role in cognitive and functional health

Conceptual design study for a teleoperator visual system, phase 2

An analysis of the concept for the hybrid stereo-monoscopic television visual system is reported. The visual concept is described along with the following subsystems: illumination, deployment/articulation, telecommunications, visual displays, and the controls and display station

Virtual acoustics displays

The real time acoustic display capabilities are described which were developed for the Virtual Environment Workstation (VIEW) Project at NASA-Ames. The acoustic display is capable of generating localized acoustic cues in real time over headphones. An auditory symbology, a related collection of representational auditory 'objects' or 'icons', can be designed using ACE (Auditory Cue Editor), which links both discrete and continuously varying acoustic parameters with information or events in the display. During a given display scenario, the symbology can be dynamically coordinated in real time with 3-D visual objects, speech, and gestural displays. The types of displays feasible with the system range from simple warnings and alarms to the acoustic representation of multidimensional data or events

The system integration and verification testing of an orbital maneuvering vehicle for an air bearing floor

The teleoperator and Robotics Evaluation Facility (TOREF) is composed of a 4,000 square foot precision air bearing floor, the Teleoperator Motion Base, the Target Motion and Support Simulator, the mock-ups of the Hubble Space Telescope, Multi-mission Modular Spacecraft, and the Orbital Maneuvering Vehicle (OMV). The TOREF and its general capabilities to support the OMV and other remote system simulations; the facility operating procedures and requirements; and the results of generic OMV investigations are summarized
