Abstract:
The purpose of the pilot study was to examine the psychological and physical symptoms reported by video display terminal (VDT) and non-VDT users in relation to intensity and duration of VDT exposure, ergonomic characteristics of the work station, workers' perceptions of the working environments, medical conditions, job satisfaction, and mood states. Thirty VDT users and 16 non VDT users were selected from four departments of a major radiopharmaceutical company for participation in the cross-sectional study. Self-administered questionnaires were utilized to obtain information on symptoms, medical conditions, job satisfaction, mood states, and the working environments. Objective measurements were obtained to provide information on the various ergonomic components of the work station. The study corroborated findings reported in previous studies, whereby eye related symptoms were associated with VDT usage. A higher percentage of symptoms were reported among VDT users even when they had more control over their work stations. These workers expressed higher levels of job satisfaction, and lower levels of tension, fatigue, con-fusion, anger, and depression than non-VDT users. Most importantly, a trend in symptomatology was identified, whereby symptoms appeared to increase as duration of VDT exposure increased.

Abstract:
Information processing has altered the structure of the traditional office. Typewriters are no longer a necessity to prepare written business communication. As a result of a metamorphosis from manual data manipulation to electronic data processing, microcomputers and their related peripheral equipment are becoming the key link in the information system. Increased usage of microcomputers and word processing software has been linked to decreased proficiency in detecting errors and in turn to decreased office productivity. Thus a number of questions arise including: Is it better to proofread from a hardcopy or a softcopy document? Does the color and contrast configuration of a video display terminal affect the operator's ability to proofread? The effect on the operator's ability to accurately detect errors in keyboarded text from different media has not been previously determined. This study was therefore completed to ascertain if a difference does exist. Seventy-two individuals enrolled in four word processing classes at a western North Carolina community college comprised the individuals participating in this study. Participants completed a demographic questionnaire, a pretest instrument, and one of four error detection instruments. The error detection instruments were presented in either a hardcopy or softcopy format. The softcopy format consisted of three video display terminal configurations. Analyses of covariance with pretest scores used as the covariate were used to compare the quantity and types of errors detected by error detection environment configurations. Based on the findings from the analyses of data the following conclusions were derived. 1. Postsecondary word processing students have difficulty in finding errors in hardcopy and softcopy documents. 2. Postsecondary word processing students' abilities to detect errors in keyboarded text were not affected by the error detection environment–hardcopy or softcopy–during a ten-minute error detection process. Therefore, the printing of a hardcopy of keyboarded text when detecting errors for a short time period is not necessary. 3. Postsecondary word processing students' abilities to detect errors in keyboarded text were not affected by the video display terminal configurations examined in this study. A video display terminal’s color configuration is not a factor in the error detecting process for a short time period-ten minutes. Therefore, the color configuration of a video display terminal should not be a major consideration when purchasing new video display terminals for instructional use. 4. As the spelling Verification feature of word processing software does not detect all types of errors, instruction is needed in detecting errors that cannot be detected by the software’s spelling Verification feature.

Abstract:
The study investigated grade 6 students' comprehension of narrative text when presented on a computer and as printed words on paper. A set of comprehension tests were developed for three stories of varying length (382 words, 1047 words and 1933 words) using a skills hierarchy protocol. The text for each story was prepared for presentation on a Macintosh computer using a program written for the study and as print in the form of exact copies of the computer screen. Students from two grade 6 classes in a suburban elementary school were randomly assigned to read one of the stories in either print form or on the computer and subsequently completed a comprehension test as well as a questionnaire concerning attitude and personal information. The responses from the comprehension tests were evaluated by graduate students in Language Education. The data evolved from the tests and questionnaires were analysed to determine measures of test construct validity, inter-rater reliability, and any significant difference in the means of comprehension scores for the two experimental groups for each story. The results indicated small but insignificant differences between the means of the three comprehension test scores for computer and print. A number of students reading from the computer complained of eye fatigue. The scores of subjects reading the longest story and complaining of eye fatigue were significantly lower.

Abstract:
The current study investigated the task performance and subjective preference for two color displays with differing image generation technologies, the standard cathode ray tube shadow mask (CRT) display and the newer liquid crystal/cathode ray tube (LC/CRT) display. Six subjects performed three different information processing tasks using each of the two color display technologies and expressed their display preference via evaluation questionnaires. Ambient illumination measurements were obtained to determine preferred conditions for each display. A four-way factorial design was used to collect task performance data and ambient illumination preferences; performance data were collected as errors per unit task quantity for each of the task types. Subjective evaluations consisted of 20 five-interval bipolar adjective scales and a forced choice rating on eight display parameters. An analysis of variance procedure and post-hoc Newman-Keuls analyses were employed in the analyses of the performance and subjective bipolar adjective scale data; the forced choice rating scales were evaluated using the Sign Test. The task performance results indicate that neither display produced better task performance. The subjective data revealed mixed results; while the bipolar adjective scales indicate no differences between the two display technologies, the forced choice rating shows a preference for the LC/CRT display on some display parameters. A significant difference between the two displays was demonstrated for ambient illumination preferences; the LC/CRT was viewed in greater ambient illumination than the CRT display.

Abstract:
This dissertation examined the effects of display spatial luminance nonuniformities on operator performance and perception. The objectives of this research were to develop definitions of nonuniformity, develop accurate measurement techniques, determine acceptable levels of nonuniformities, and to develop a predictive model based on user performance data. Nonuniformities were described in terms of spatial frequency, amplitude, display luminance, gradient shape, and number of dimensions. Performance measures included a visual random search task and a subjective measure to determine users' perceptions of the nonuniformities. Results showed that users were able to perform the search task in the presence of appreciable nonuniformities. lt was concluded that current published recommendations for acceptable levels of nonuniformities are adequately specified. Results from the subjective task showed that users were sensitive to the presence of nonuniformities in terms of their perceptions of uniformity. Specifically, results showed that as spatial frequency increased, perceived uniformity ratings increased. That is, users rated nonuniformities to be less noticeable. As amplitude and display luminance increased, the users' ratings of perceived uniformity decreased; that is, they rated the display as being farther from a uniform field. There were no differences in impressions between a sine and triangle gradient shape, while a square gradient shape resulted in lower ratings of perceived uniformity. Few differences were attributed to the dimension (1-D versus 2- D) of the nonuniformity and results were inconclusive because dimension was confounded with the display luminance. Nonuniformities were analyzed using Fourier techniques to determine the amplitudes of the coefficients for each nonuniformity pattern. These physical descriptors were used to develop models to predict users' perceptions of the nonuniformities. A few models yielded good fits of the subjective data. lt was concluded that the method for describing and measuring nonuniformities was successful. Also, the results of this research were in strong concurrence with previous research in the area of spatial vision.

Abstract:
Abstract Video display terminals (VDTs) were first associated with adverse reproductive outcomes in 1980, when a cluster of birth defects was observed among women using VDTs at the Toronto Star newspaper. This report was followed by a number of other adverse pregnancy outcome clusters, primarily spontaneous abortion, but including other adverse outcomes such as stillbirths, low birthweight, and preterm birth (Berquist, 1984). Three different hypotheses were proposed as possible explanations for the clusters: (1) physical stress (defined as prolonged sitting), (2) psychological stress due to the demands of the work environment, and (3) electromagnetic energy emissions (Tell, 1990). As of 1984, no epidemiologic studies of VDT and pregnancy outcome study were underway in the United States, and the literature contained little information on the potential hazards of VDTs. While physical stress, defined as heavy lifting, had been associated with an increased risk of preterm birth (Mamelle et al., 1984), the association with work posture (sitting versus standing) had not been studied. There was little information about the potential effect of workplace psychological stress on reproductive function, although two studies had shown an association between a measure of occupational mental stress and premature birth (Mamelle et al., 1984; Naeye and Peters, 1982). No animal or human studies had been conducted of the potential reproductive hazards of electromagnetic fields produced by VDTs. These electromagnetic fields were of two types, ELF (extra-low frequency) and VLF (very low frequency). These two frequencies are in the lower end of the electromagnetiic spectrum, below radio waves or microwaves. ELF fields are also produced by common 60 Hz wiring in houses and appliances. Studies of the reproductive effects in animals exposed to ELF and VLF were just beginmng.

Abstract:
Using of computers and other video display terminals (VDTs), such as laptops, smart phones, tablets, e-readers, and even watches, are part of our everyday life and more and more users are experiencing a variety of ocular and non-ocular symptoms related to computer use. These complaints include eyestrain, tired eyes, headaches, eye irritation, eye redness, itching, blurred vision, double vision, dry eye, and neck, back, and shoulder pain as extra-ocular issues, which have been termed computer vision syndrome (CVS). Based on pieces of evidence, between 64% and 90% of computer users experience visual symptoms. Children are also affected as they spend many hours each day using digital devices with visual displays for doing schoolwork, especially after starting the COVID-19 era, playing video games, and sending and receiving text messages on cell phones. With the increased use of these electronic devices, CVS is becoming a major public health issue. Proper identification of symptoms and causative factors is necessary for the accurate diagnosis and management. There are some strategies for reducing the complaints related to prolonged use of digital screen devices.

Abstract:
Abstract Although recent advancements in information technology (IT) have contributed substantially to the quality of leisure time, a range of mental and physical problems have been attributed to sustained use of a range of visual displays, to which the terms IT syndrome and visual display terminal (VDT) syndrome , have been applied. This disorder comprises a complex of eye and vision problems and systemic symptoms in individuals who experience sustained and prolonged proximity to visual displays with electromagnetic fields (such as computer screens, televisions, and cellular phone screens). Use of computers in the workplace has increased greatly, and has been accompanied by the development of a number of health concerns. Thus, many individuals who work with VDT, television, television games, personal computers (PCs), mobile video games, and mobile phones have complained of ocular discomfort and eye muscle strain and stress. Several studies reported that the majority of VDT workers experience some eye or visual symptoms,-including eyestrain; headaches; blurred vision; dry, red, or irritated eyes; and double vision.

Abstract:
Managers must strive for a healthy and productive working environment for end users. Eliminating or reducing lost work days and improving worker productivity in turn relates to the organization’s profitability. VDT related health issues are important to end users, managers, and the organization as a whole. End user computing is becoming commonplace in most businesses. In 1993 more than forty-five percent of the US population used computers at work according to the US Department of Labor (1997). The proliferation of end user computing creates a host of management issues. One such issue involves the potential health hazards associated with video display terminal (VDT) use. Both managers and end users must address this issue if a healthy and productive work environment is to exist.

Abstract:
The multitrading information environment provides simultaneous work with several financial instruments on many trading accounts of different forex brokers using optimal trading strategies (scalping, swing trading and positional trading). The hardware complex of multitrading is composed of Analytical, Operational and Overview displays, the operation of which is provided by separate computers. The characteristics of the hardware base of multitrading, which provide reliable and comfortable work in stationary and mobile conditions, have been determined. The principles of optimizing the configuration and color design of the contents of the displays of the multitrading system have been established. The Analytical display consists of 6 Analytical windows with progressively increasing time scales (timeframes) and is used to work with one (most liquid) financial instrument. The Analytical window contains a price chart and three Indicator windows, which are grouped by compatibility, purpose (anticipatory, main, confirming) and specificity (trend, oscillators, volume indicators). A technique is proposed for unmasking the latent phases of oscillation trends by Complex Indicators of Tendencies, which are formed through the sequential application of trend indicators of technical analysis to the data of oscillatory indicators. The Overview display (6-8 Analytical windows with the same timeframe and different financial instruments) provides a tactical choice of the instrument to be connected to the Analytical display windows. The Operational display allows a trader to simultaneously work with orders from multiple trading accounts of different brokers in separate browsers with web terminals. A set of suitable browsers and their specific settings have been determined. The article discusses the basic concepts necessary for the use of multitrading, defines the criteria for choosing the optimal brokers, trading platforms and forex terminals. A methodology for creating and using round-the-clock video recordings of the multitrading displays has been developed. A network of Internet services has been formed to exchange experience in optimizing the information environment of multitrading. Based on the results of three years of experimental work, methodological techniques were selected that contribute to the development of an individualized trading system based on the multitrading information environment.

Abstract:
In this study, we propose an XR (cross reality) dialogue system that transmits an omnidirectional stereoscopic moving viewpoint image of a remote real space and presents it to a local worker with an HMD (Head Mounted Display), and the worker faces the stereoscopic avatar (face part) of the local worker presented with MR glasses. The system is asymmetrical.This system is asymmetric. The position and orientation of the head and eyes measured by the HMD (Vive Pro Eye, HTC) at the local site are transmitted to the remote space, and the avatar of the local worker is shown by the MR glasses (Magic Leap, HoloLens2). The CG object and avatar (the face of the local worker) are shared with the remote 3D real space. This enables the remote worker to see the face of the local worker who has the viewpoint position on the TwinCam Go mobile stereoscopic camera.We conducted an experiment to evaluate the reality of the avatars presented in the MR glasses of the field workers as interactors and the clarity of the instructions for the spatial objects to be discussed. The participants in the experiment were seven university (graduate) students (aged 21-24). The communication time of this system was about 70 ms one way. The G.1010 of ITU-T recommends that the delay between terminals for real-time video communication should be less than 150 ms one way.The experiment participants stood in front of the stereoscopic camera (TwinCam) as remote experiencers, and wore MR glasses to see the avatars of the local experiencers (wearing HMDs). The local operator describes three spatial objects (a cube, a sphere, and a cone) that are displayed 1.7 m closer to the experimental participant from the remote camera.Analysis of variance showed that the reality and clarity of the dialogue increased at the 1% significance level when the avatar's head rotation and eye movements were present. The 3D projection display was higher than 2D at the 5% level of significance. The clarity of the subject improved at the 5% level of significance when there was head rotation and eye movement, but the 3D projection was not significantly different from the 2D.This indicates that the 2D monitor without binocular disparity has a large reading error in the depth direction. Another clue is that the HMD and MR glasses can utilize motion parallax by moving the head even slightly. This makes it possible to reduce the error to less than about half that of a 2D monitor.In this study, we developed a cross reality (XR) dialogue system for mobile remote collaboration. As a result of three kinds of evaluation experiments, it was shown that the clarity of dialogue and the accuracy of depth indication were improved compared with the condition of the conventional 2D video teleconference. This system can also be integrated with the metaverse, and can provide a variety of remote experiences of the world even when mobility is restricted due to current contagious disease. In the future, we will continue to verify and demonstrate the technology necessary for smooth telecommunication.
