TL;DR: Recommendations are offered concerning design and use of VR systems in order to minimise VRISE as the most notable finding was that of high inter- and intra-participant variability.

TL;DR: The background, theories, and observations on visual stress possibly caused by viewing stereoscopic motion images, including changes in pupillary responses, are reviewed and Evaluation of visual fatigue, particularly in relation to different methods of viewing stereoscope displays is described.

TL;DR: Einstein's gelijkheidsprincipe, neurofysiologie en regeltechniek wordt een raamwerk geboden voor het begrijpen, voorspellen en nader onderzoeken of het verschijnsel dat the authors misselijk kunnen worden van het kijken naar bewegende beelden.

TL;DR: A review of the state-of-the-art in the physiological and technological principles, considerations and characteristics, as well as latest implementations of microactuator-based tactile graphic displays, to demonstrate the potential and limitations in tactile applications.

TL;DR: A questionnaire was developed to subjectively assess visual fatigue caused by viewing various types of motion images, which revealed five factors: Eye Strain, General Discomfort, Nausea, Focusing Difficulty, Headache and Headache, which were effective for classifying motion images.

TL;DR: The habituation which occurred was of a similar nature in all of the participant groups regardless of exposure interval, indicating that the number of exposures is a more important factor than the time interval between them.

TL;DR: A redesigned prototype was constructed as an alternative to the current simulator and hardcopy procedure manuals and improves upon the graphical layout of system information and provides better integration of procedures, automation and alarm systems.

TL;DR: A new hybrid method composed of the geometrical optics and the extended Jones matrix methods was developed, and applied to the modelling of the light leakage around a spherical object in a twisted nematic liquid crystal layer.

TL;DR: It seems that E-paper displays may need greater illumination (700 lx or higher), greater character size (3.3 mm or 22 min of visual angle) and the effect of character size on accuracy was also significant.

TL;DR: The effects of figure/background color combinations, the type of computer icon and the figure/ Background area ratio on visual search performance on a liquid crystal display (LCD) screen showed that these three independent variables significantly affected theVisual search performance.

TL;DR: Results showed that surface treatment significantly affected legibility and visual fatigue, and surface treatment can improve legsibility and reduce visual fatigue under intense ambient illumination, however, there is no significant difference on bending curvature.

TL;DR: Eu 2+ , Dy 3+ and Gd 3+ co-doped strontium aluminate yellow-green phosphor was synthesized by combustion method using urea as reducer at 600 °C and the initial brightness improved and the afterglow time prolonged.

TL;DR: Analyzing the collected data showed that students’ severities of the sickness related with their viewing distance to the video image, their concentrations on the video movie, their getting a cold, and their daily playing hours of video games.

TL;DR: The use of screen printing is demonstrated in the fabrication of highly efficient phosphorescent polymer organic light-emitting devices (OLEDs) based on a green-emitted Ir(ppy)3 and a host polymer PVK and incorporates PBD in the polymer host as an electron-transporting dopant and a-NPD as a hole-transport dopant.

TL;DR: A sharp decrease in luminance was found on formation of the di- n -heptyl viologen radical cation salt, implying that specific choice of colour values depends on both the potential applied and from which direction the potential is changed.

TL;DR: The technique is suggested for a kind of pulse-width-modulation LED dimming in LED video displays where the significant increase of the gray levels number and image refresh frequency can be achieved when the large number of LEDs is controlled serially.

TL;DR: It is concluded that time-based and environment-based factors influence operator visual fatigue and task performance during dynamic VDT work.

TL;DR: The results indicate that the surface-textured ITO method utilizing the natural lithography combined with the inductively coupled plasma (ICP) etching technology has high potential in future large-area high-power GaN LED applications.

TL;DR: The PCA results showed that the usability of touch icons was affected by seven factors: touch field, semantics quality, dynamics, hit quality, tactility, color quality, and shape quality; among these, touch field was rated as being the most important.

TL;DR: It is indicated that LED PWM dimming fails to satisfy the required 14 bit output coding together with the image refresh frequency of 400 Hz, and the nonlinearity correction for the PWM pulse durations shorter than the skew value should be possible.

TL;DR: The results showed that motion sickness as evaluated by a simulator sickness questionnaire increased as the horizontal field of view increased, and the autonomic nervous index demonstrated that viewing vibrating sequences activated the sympathetic control of the viewer.

TL;DR: The results show that, while ClearType rendering does not improve text legibility, reading speed or comfort compared to perceptually-tuned grayscale rendering, subjects prefer text with moderateClearType rendering to text withgrayscale or higher-level ClearType contrast.

TL;DR: Investigation of the effect of vibration on visual performance and fatigue for several numerical display design characteristics including the font size and the number of digits displayed showed that whenever the display is used in vibration environment, an increased font size may be an effective way to compensate the adverse effect of vibrations.

TL;DR: The results showed that there were significant differences in the causal coherence functions as well as the traditional coherence function between the subjects who felt VIMS and those who did not, and that the hemodynamic system was mainly disturbed by VIMs rather than the baroreflex system.

TL;DR: This study investigated a multi-response problem in terms of searching time, number of missing characters/buttons (NMCB), and visual fatigue by integrating the Taguchi method and the weighting method to optimize the Chinese interface design parameters such as display type, character size, font type, and text/background color combination in motion environments.

TL;DR: A 10-year longitudinal study, currently underway in the U.K., has been implemented to definitively answer the question of whether long-term exposure produces any degradation in binocular visual function.

TL;DR: Its maximum luminance was 27360 cd/m2 at 15 V and maximum power efficiency was 3.16 lm/W at 7 V, which is largely insensitive to the current density.

TL;DR: A comparative characteristics study of the new complexes with that of Alq3 revealed that thenew complexes are somewhat better than Alq2, while devices prepared by physical vapor deposition and by spin coating showed poor performance.

TL;DR: A scarce variation for different levels of expertise in relation to symbols, but only for icons depicting real-world objects, an overall better performance for objects and no significant response to the context are indicated.

TL;DR: For video images that strongly induced cybersickness, zone intervals with a high correlation coefficient between local and global motion vectors were located at the peaks of trigger points in the time-distribution obtained from 25 subjects.
