| Summary: | 碩士 === 中原大學 === 工業工程研究所 === 92 === Today, various digital products, such as electronic <a href="http://www.ntsearch.com/search.php?q=books&v=56">books</a>, electronic periodicals, and <a href="http://www.ntsearch.com/search.php?q=multimedia&v=56">multimedia</a>, have changed the way <a href="http://www.ntsearch.com/search.php?q=people&v=56">people</a> receive information. The article is usually too long for <a href="http://www.ntsearch.com/search.php?q=people&v=56">people</a> to read from an electronic display. Scrolling information in a window becomes an effective way for this problem. <a href="http://www.ntsearch.com/search.php?q=People&v=56">People</a> always control the scrolling bar in order to read the information outside the current window.
An experiment was carried out to investigate the effects of scrolling dynamic information on visual performance and fatigue. Two independent variables of this experiment are reading speed (600 wpm, 1000 wpm and 2000 wpm) and advance resolution (1 pixel, 2 pixels, 3 pixels and 4 pixels) of scrolling display. Dependent variables include miss rate, vision, critical fusion frequency (CFF), blink rate, and subjective rating.
The results were as follow. The three reading speed (600 wpm, 1000 wpm and 2000 wpm) had significant effects on the visual performance. The <a href="http://www.ntsearch.com/search.php?q=search&v=56">search</a> performance was better when reading at 600 wpm. It had the worst performance when reading at 2000 wpm. The four advance resolution (1 pixel, 2 pixels, 3 pixels and 4 pixels) had significant effects on the visual fatigue. There was less visual fatigue when scrolling at 1 pixel. There was more visual fatigue when scrolling at 4 pixels.
