| Abstract: | 本研究欲探討圖形呈現與RSVP圖形資料界面應用在小螢幕設備上的量化視覺績效效果。三種圖形呈現媒介--分為折線圖（line graph）、長條圖（bar graph）、與地圖（map）和五種RSVP圖形資料界面包括：旋轉木馬型（carousel）、拼貼型（collage）、物架型（shelf）、孔洞型（keyhole）與傳統型縮圖（convention）。研究目的為在小螢幕上評估理想的量化資料介面。圖形認知任務包含精確判斷、識別趨勢、兩點比較和極值判定。實驗一（24名受試者）與實驗二（36名受試者）均採行三因子區集實驗設計，透過實驗的方式搜集相關之數位訊息解碼績效。實驗一與實驗二的結果均顯示RSVP與圖形呈現的交互作用項與圖形呈現與圖形認知任務的交互作用項的效果均為顯著的。對於精確判斷與識別趨勢的任務而言，在任何一種RSVP設計下，折線圖與長條圖均顯著的比地圖來的好。對於兩點比較任務而言，拼貼型-地圖、物架型-地圖、傳統型-地圖、旋轉木馬型-長條圖與孔洞型-長條圖的組合設計有較短的平均反應時間。對於拼貼型-折線圖的組合設計在兩點比較任務是不被推薦的。對於極值判定任務而言，旋轉木馬型-長條圖、孔洞型-長條圖與孔洞型-折線圖是值得被推薦的組合設計，然而，孔洞型-地圖則是在小螢幕不被推薦的組合設計。
In this study, we focus on the effects of types of graphical display and modes of rapid serial visual presentation (RSVP) interface on the visual performance of quantitative data on the small screen devices. Three types of graphical displays, including line graph, bar graph, and map, and five modes of RSVP interfaces, including carousel mode, collage mode, shelf mode, keyhole mode, and convention mode will be considered as the design factors. The objective is to evaluate the optimal visualization interface of quantitative data on a small screen. Graphical perception tasks are including reading the exact value, identifying the trend, comparing two values, and reading the maximum value. Two factorial experiments with blocks were applied to Experiment 1 (twenty-four participants) and Experiment 2 (thirty-six participants). The results of Experiments 1 and 2 show that both the interaction of RSVP and graphical display types as well as the interaction of graphical perception tasks and graphical display types are statistically significant. For the tasks of reading the exact value and identifying the trend, line and bar charts are significantly better than map for any kind of RSVP designs. For the comparing two values, the collage-map, shelf-map, convention-map, carousel-bar, and keyhole-bar designs have the relatively smaller mean response times. It should not be recommended for collage-line design for comparing values. For the reading the maximum value, carousel-bar, keyhole-bar, and keyhole-line designs are worthy of recommendation but keyhole-map design is not recommended for the small screens. |
