Guidelines for Using Heatmaps (X) let’s-track-and-see-what-happens approach (2) Define the 2D-data represented (1) Used for visualizing quantitative data (3) Define a fixation; e.g., 100ms, 0.5 (4) Define the upper bound for color scale (5) Describe the timeduration when fixations were collected

  2. Case Study: ASCO Original ASCO homepage Proposed ASCO homepage With which users can be quicker to find information?

  3. CoLiDeS(Comprehension-based Linked Model of Deliberate Search) 假設你要到紐西蘭度假，並且希望可以跟家人 在南島的國家公園散步。假設你需要從網頁中 找到相關資訊。 請放聲說明你進入下列網頁之後的想法：包括 想做的動作、為什麼想做： http://www.peaktopeak.net/

  5. Bad Examples of Visual Search         Attention deployment Target processing Visual design Ease of understanding

  6. Participants and Apparatus • 12 participants • Age: 30-55 • ASCO member • Recruited at 2005 ASCO Annual Meeting in Orlando • Use experience: once a month (mean) • Apparatus • 17” monitor (1024 x 768 pixels) • a mouse • Tobii 1750 eye tracker

  7. Procedures • Within-subjects design • Counterbalanced against sequence effect • Randomized 25 tasks (Design 1) 20-min unrelated exercises 25 tasks (Design 2) Randomized Randomized Any confounding effect between old vs. new?

  8. TASK I: Find a list of upcoming conferences Original webpage Proposed webpage

  9. Analysis Results

  10. What Color Scheme Is Better? Red-Orange-Yellow-Blue-Gray Red-Orange-Yellow-Green-Gray

  11. Grayscale Scheme

  12. White Background?

  13. Gaze Plot&Gaze Replay • What they are? • Place • Order • Size • Limitations • 有時候看不到數字 • 有時候看不到網頁 • Time-consuming • Gaze replay Qualitative nature
