摘要

本研究旨在探討雙行動態訊息之訊息顯示位置、配速與雙行訊息之間距因子對於讀取理解力與視覺疲勞的影響。研究為三因子實驗設計（2 x 4 x 3），由顯示位置、顯示配速及雙行訊息之間距作為獨立變。依變項為閱讀理解力和視覺閃光融合閾值。研究結果顯示：（1）動態訊息置於不同的位置對受測者的讀取理解力有顯著的差異。當動態訊息的顯示位置於下方時，其閱讀理解力優於左方。（2）當動態訊息雙行並列時，雙行之間距大小並不會造成受測者閱讀理解力之差異，介於0.5公分~ 2 公分之距離為受測者可接受之距離。（3）顯示配速的不同對於受測者讀取理解力有顯著影響，當前導式雙行動態訊息的配速設定在200/ 85 cpm、85/ 200 cpm 和 85/ 85 cpm之組合時，其受測者的閱讀績效優於配速設定在200/ 200 cpm時的讀取理解力。（4）較長的休息時間，有助於提升受測者的讀取理解力。本研究結果將可提供電視媒體動態資訊製作與相關研究之參考，以提升電視畫面上動態訊息之視覺呈現品質與訊息讀取績效。

This study examined the factors（position, speed, and double-lined distance） affecting viewers’ comprehension and visual fatigue pertaining to the reading of double-lined dynamic information on an LCD screen. A three-way factorial-design experiment（4 x 3 x 2）using different positions, speed combinations of in-line/out-line, and distances between the up-line and below-line as independent variables was conducted to test the comprehension and visual fatigue associated with reading information on a leading display. The results of this study were as the follows:（1）normally, double-lined dynamic information positioned on the bottom of the TV screen was better than that on the left side of the TV screen.（2）There were no differences among the distances of 0.5, 1.25, and 2 cm between the up-line and below-line.（3）There were differences on account of the various speed combinations. The double-lined speed combinations with 200cpm/85cpm（up-line/below-line）, 85cpm/200cpm, and 85cpm/85cpm were better than the speed combination with 200cpm/200cpm.（4）The longer break may improve the reading comprehension. These results could be used as a reference for websites and TV screen designers for identifying the appropriate levels of displaying leading-display.
