    Letter Transposition Project [GELLAB 2018]
    (2018-11-16) Xiong, Yingzi; Chen, Qiaoyue; Legge, Gordon E; yingzi@umn.edu; Xiong, Yingzi; Minnesota Low Vision Lab
    We used a letter transposition (LT) technique to investigate letter position coding during reading in central and peripheral vision. Eighteen subjects read aloud sentences in a rapid serial visual presentation (RSVP) task. The tests contained a Baseline and three LT conditions with Initial, Internal and Final transpositions (e.g., “reading” to “erading”, “raeding” and “readign”). In each block 6 word-exposure times (central reading: 34, 51, 76, 113, 168 and 250 ms; peripheral reading: 53, 93, 165, 290, 511 and 900 ms) were measured in a random order, each tested 8 times. Eight blocks were tested, with each reading conditions tested once in both central and peripheral vision in a random order.

    Reconciling Print-Size and Display-Size Constraints on Reading (Minnesota Lab for Low-Vision Research, 2020)
    (2020-03-20) Atilgan, Nilsu; Xiong, Yingzi; Legge, Gordon E.; atilg001@umn.edu; Atilgan, Nilsu; University of Minnesota - MN Lab for Low Vision Research
    The data includes both normally-sighted (Times and Courier groups) and low-vision subjects' reading performance. The main dependent variable in this dataset is reading speed. Reading speed measure is indicated by how many characters per minute were read. In addition, two independent variables with their different levels are provided. These variables are display format (laptop, tablet, phone) and blur condition for normally-sighted participants (normal-viewing condition and viewing under artificial blur through goggles).
