It is well known that fluorescent traffic sign have a daytime conspicuity that is far superior to that of normal color signs. This study was conducted in order to test the hypothesis if adding the property of fluorescence while leaving all (or in practical terms most) other sign features the same, does in fact increase the legibility distance. Six diamond shaped signs were fabricated and lamina...

PURPOSE We performed an analysis of the smartphone legibility of the websites of the Korean Urological Association (KUA) and other urological societies. MATERIALS AND METHODS This study was conducted on the websites of the KUA and nine other urological societies. Each website was accessed via iPhone Safari and Android Chrome, respectively, to evaluate the establishment and readability of the ...

Standardized writing assessments such as the Minnesota Handwriting Assessment (MHA) can inform interventions for handwriting difficulties, which are prevalent among school-aged children. However, these tests usually involve the laborious task of subjectively rating the legibility of the written product, precluding their practical use in some clinical and educational settings. This study describ...

OBJECTIVE To analyze readability and legibility of a systematic sample of health education materials made available at a health center, and to propose recommendations for improvement. DESIGN Observational, descriptive study. SETTING An urban health center in Madrid, Spain. MATERIAL A sample of text from 326 health education documents. MAIN MEASURES The 326 texts were classified accordin...

OBJECTIVE The purpose of this study was to examine the relationship of performance on the Developmental Test of Visual-Motor Integration (VMI; Beery, 1997) to handwriting legibility in children attending kindergarten. The relationship of using lined versus unlined paper on letter legibility, based on a modified version of the Scale of Children's Readiness in PrinTing (Modified SCRIPT; Weil & Cu...

OBJECTIVE Children with ADHD often present with handwriting difficulties. However, the extent to which motor and attention skills influence performance in this group has not yet been explored. The objective of this study was to examine the factors associated with change in handwriting performance. METHOD This study examines the factors associated with change in handwriting performance of 49 c...

This study investigates the hypothesis that variations in symbol sign legibility distance can be accounted for on the basis of a sign's dependence upon high spatial frequency contours to convey critical information. Using digital image processing techniques, highway signs were blurred to remove all high spatial frequency information. A blur recognition threshold was established for each experim...
