中文摘要 隨著社會高度資訊化發展,我們的環境中充斥著多種訊息傳播方式,其中LED動態顯示器因具有諸多優點而被廣泛應用來傳達公眾資訊。然而LED動態訊息因為具有高亮度、多彩顯示、動態呈現與點陣式顯示等特性,而增加了閱讀者,特別是高齡者在接收公共訊息時視覺上的負擔。此外,公共場所中的干擾也使得高齡者較容易受影響而分心,因此LED動態顯示器所傳播的公眾資訊就無法完整地被高齡者吸收與利用。為了改善這些問題,本研究透過文獻探討建立研究假設「重點標示設計可以提昇高齡者對LED動態訊息的接收度」,並進一步利用自由回想實驗探討「無重點標示」以及「改變字色」、「加入括號」及「改變背景顏色」等三種常見的重點標示設計對高齡者在受聲音干擾下接收LED動態訊息時的影響性。研究結果顯示「加入括號」為可以提昇高齡者在受聲音干擾時,對LED動態訊息接收度的重點標示設計,其提昇效果在高齡者接收訊息後的10秒內最佳,最久則可持續至高齡者接收訊息後的30秒內。「改變背景顏色」是對高齡者而言次佳的重點標示設計。然而,最常用被使用來標示關鍵訊息的「改變字色」,在本研究中的效果則最為不佳。因此本研究建議在高齡者經常出入的公共場所中,使用「加入括號」來強調LED動態訊息的重點。而在高齡者回想的關鍵字詞數量方面,「加入括號」組平均回想的關鍵字詞數量為5.06個,「改變字色」組平均回想的關鍵字詞數量則為3.56個。因此本研究建議在給高齡者閱讀的句子中(約80個中文字),關鍵字詞的數量可以大於3個,但以不超過6個為佳。
英文摘要 As the amount of information available to our society increases, so do the kinds of technology available for the public to use. Among these technology types, dynamic LED displays have been widely adopted to convey information in public places. However, dynamic LED information featuring high brightness, multi-color displays, dynamic performance and dot-matrix displays, etc., will increase the visual load of receiving information to an uncomfortable level for some viewers, especially for the elderly. In addition, environmental interferences in public spaces also frequently distract attention of the elderly. Therefore, public information shown on dynamic LED displays is not received or utilized very well by elderly citizens.To address these problems, this study proposed a research hypothesis " highlighting design might can improve elderly's dynamic LED information reception ratio ". First there would be a literature review and then a free recall experiment to explore the effects of no highlighting design (Non) and three frequently utilized highlighting designs: "Changed font color", "Added square brackets" and "Highlighting (or changed background color)”.The experimental results indicated that "Added square brackets" was the best highlighting design, which improved elderly's reception ratio of dynamic LED information in this study. The effect of “Added square bracket” performed best within 10 seconds after reading, and the duration of its effect was longest for 30 seconds after reading. "Highlighting (or changed background color)” was the second-best highlighting design for the elderly. However, the most frequently utilized "Changed font color" was the worst highlighting design in this study. The amount of recalled keywords in "Added square brackets" group averaged about 5.06, but about 3.56 in the "Changed font color" group. Therefore, this study suggests that for emphasizing keywords of dynamic LED information, we should adopt the “Added square brackets” style to improve the elderlies’ reception ratio of dynamic LED information. In general, the amount of keywords in an 80 Chinese characters sentence can be over 3 but should less than 6 keywords for the elderly.
