Lateral interference, spacing, and word legibility
نویسنده
چکیده
Visual processing of individual characters within a word can interfere with one another thereby decreasing word legibility. This largely results from the lateral interference occurring in the retina and the primary visual cortex, with the distance over which it operates largely fixed in size. Analysis of previous data demonstrates that the default spacing for 10 and 12 pt font is just large enough to avoid significant lateral interference effects. These results suggest that empirical design skirts the limit of lateral interference and that lateral interference is to be avoided for good design.

The effects of interletter spacing in visual-word recognition.
Despite the importance of determining the effects of interletter spacing on visual-word recognition, this issue has often been neglected in the literature. The goal of the present study is to shed some light on this topic. The rationale is that a thin increase in interletter spacing, as in casino, may reduce lateral interference among internal letters without destroying a word's integrity and/o...
متن کاملSerifs and font legibility
Using lower-case fonts varying only in serif size (0%, 5%, and 10% cap height), we assessed legibility using size thresholds and reading speed. Five percentage serif fonts were slightly more legible than sans serif, but the average inter-letter spacing increase that serifs themselves impose, predicts greater enhancement than we observed. RSVP and continuous reading speeds showed no effect of se...
متن کاملThe Effect of Text Typographical Features on Legibility, Comprehension, and Retrieval of EFL Learners
This experimental study investigated the relationship between font type, font size, and line spacing and legibility, as measured by speed of reading, comprehension, and recalling. Instruments for testing legibility and reading comprehension were presented in eight typographical styles in print. The study tested 90 students for legibility and 76 students for comprehension. The subjects were chos...
متن کاملLegibility of outline and solid fonts with wide and narrow spacing
Using a visual acuity criterion for legibility, outline fonts are about 82% less legible than their solid counterparts. Crowding effects are similar for the two types of fonts. Both sets of results can be adequately explained by contrast sensitivity of visual channels serving 1-4 c/character.

OBJECTIVE This study examined the test-retest reliability of the legibility portion of the Evaluation Tool of Children's Handwriting-Manuscript (ETCH-M). METHOD The sample consisted of 31 first-grade and second-grade students with handwriting dysfunction. The ETCH-M was administered two times, 1 week apart, to participants. The primary investigator acted as sole rater and followed standard sc...
