The purpose of this study is to investigate the effect of the curved display on visual performance and user experience. Eye-tracking technique and self-report were adopted to assess the visual performance when watching multimedia on the curved display. For visual examination, two curvatures were chosen: flat and curved with a radius equal to 4200 mm. A series of 12 clips were presented, consist...

We report the results of 3 surveys of visual display terminal (VDT) users who took a minibreak during which they viewed a stereoscopic image of a repeating parallel pattern showing planets. The single image stereogram method employed is called Stretch Eye (TM), and we evaluated the effects of Stretch Eye (TM) on asthenopia. An accommodative relaxation of about 1 D was observed in participants w...

A scale method of computer analysis was developed as an automatic spectral analysis system of the accommodative fluctuations. The scale approach employed a computer to identify wave peaks. Using this new system. spectral analysis of the fluctuations in accommodation measured by an infrared optometer was performed. Both the power spectrum method and the scale method were used to perform a spectr...

Background: Dry eye disease (DED) is a group of tear film disturbances that are caused by decrease in production or instability. One the causes DED reduced secretion, which often happens visual display terminal (VDT) workers. Blinking therapy one therapies can be given to workers increase blink rate and reduce number incomplete blinks. Methods: Literature searching was done on database such as ...

Two experiments were performed to investigate the influence of VDT (video display terminals) and paper presentation of text on consumption of information (Study 1) measured in the form of convergent production and production of information (Study 2) measured in form of divergent production. The READ test of reading comprehension was used as the convergent task whereas the ‘‘Headlines’’ test was...

This study explores the preferred viewing distance and character size for an electronic paper display for three age groups. Proofreading speed and accuracy ratio were measured during Chinese proofreading tests using the preferred character size and minimum acceptable character size. Data analysis showed that the mean preferred viewing distance for young, middle-aged and older groups was 503, 45...

Extensive cognitive research has been devoted to the sensitivity of the visual system to invariant statistical information. For example, many studies have shown that performance improves when a visual display is presented repeatedly. But what allows humans to connect the current visual input to previous memory? Is the connection made only when the entire incoming display matches with a previous...
