BraiWe characters and letters were presented to the senses of touch and vision of sighted observers. The optical stimuli were subjected to low-pass spatial filtering to the degree that visual spatial resolution closely matched tactile spatial resolution (re the size of characters presented). In one experiment, three sets of braille characters and five sets of Roman letters, varying in typograph...

The adoption of mobile devices has been growing fast. Presently, the most challenging issues for mobile devices to access Web are power consumption due to the network activity, content navigation and the legibility of the rendering due to the screen size constraint. The existing content formatting and rendering technologies for mobile devices are limited. In this paper, we propose an architectu...

To contribute to a more comprehensive understanding of human wayfinding behaviors in complex buildings, we propose a framework that incorporates the impact of critical factors from both the environment and humans. The influence of the environment is summarized through the concept of environmental legibility, an integration of different space syntax methods that addresses visibility, connectivit...

The purpose of the research was to study changes in handwriting legibility among kindergarten, first- and second-grade students in response to the Size Matters curricular-based handwriting program. A two-group pre-post-test design was implemented at two public schools with half of the classrooms assigned to receive the Size Matters program and the other continuing to receive standard instructio...

We introduce an approach for classifying a deformed letter from the English alphabet based on its legibility. Given an image of a deformed letter d, our method proposes the use of the filtered medial axis (i.e. strokes) as its simplified representation, from which we can compute a feature vector. Based on the anatomy of the letter d we identify the strokes as: ascender, descender and counter. F...

ClearType is an onscreen text rendering technology in which the red, green, and blue sub-pixels are separately addressed to increase text legibility. However, it results in colored borders on characters that can be bothersome. This paper describes five experiments measuring subject preference, text legibility, reading performance, and discomfort symptoms for five implementation levels of ClearT...

Augmented Reality is a promising technology for the product lifecycle development, but it is still not established in industrial facilities. The most relevant issues to be addressed relate to the ergonomics: avoid the discomfort of Head-Worn Displays, allow the operators to have free hands and improve data visualization. In this work we study the possibility to use projection-based Augmented Re...

Psychophysical research on text legibility has historically investigated factors such as size, colour and contrast, but there has been relatively little direct empirical evaluation of typographic design itself, particularly in the emerging context of glance reading. In the present study, participants performed a lexical decision task controlled by an adaptive staircase method. Two typefaces, a ...

This paper examines the potential relationship between free-form handwriting (i.e., unstructured ways of writing words, phrases, or sentences by hand) and two sociolinguistic variables: the writer’s (1) age and (2) gender. While the accuracy of “gender guessing” or gender identification (e.g., Grieve, 2010; Al-Suwaiyan, 2010; Johnson, 2013) has been the focus in previous studies, this explorato...

OBJECTIVES To understand the incidence and types of medication prescribing errors in a low resource setting ophthalmology clinic and to determine the impact of a preprinted prescription based on the hospital formulary (FormularyScript) on medication prescribing errors. DESIGN Non-randomised interventional study. SETTING Ophthalmology clinic in a teaching hospital in northeast Thailand. PA...
