Perceptually-tuned grayscale fonts are generated from character outline descriptions by applying to them a set of modifications specifically conceived for strengthening thin character parts, obtaining well-contrasted bars and preserving important relationships between character shape parts. The present study aims at comparing the legibility of perceptually-tuned grayscale and bilevel display fo...

Previous laboratory research has demonstrated that symbolic highway signs which have undergone the Recursive Blur Technique of visual enhancement exhibit significantly increased legibility distances over standard symbolic highway signs when using a critical detail identification task. This study sought to extend those findings to a new stimulus subset, and develop an identification task that is...

Evidence suggests that task-based training approaches can improve the performance of children with handwriting difficulties. The present case study tests the efficacy of the Handwriting Task Program (HTP). Three male children (9-10 yr. old) with poor handwriting skills and different developmental disorders participated in the HTP, twice per week, for 13 wk. Handwriting legibility was assessed t...

This paper examines the changing nature of ethnic and religious identification in Malaysia, drawing upon a survey of attitudes conducted in three locations in Malaysia. The paper argues that the widely perceived political shift from a prevailing ethnic Malay/non-Malay dichotomy towards a more religious Muslim/non-Muslim dichotomy is more complex that previous analyses have suggested. Moreover, ...

I consider here some contemporary approaches to the live performance of computer music. Drawing upon ideas of the embodied mind and the extended mind, I will outline a theory of embodied listening which problematises some of our assumptions about music, gesture and performance. Against the background of this theory, I will argue against approaches which put too great a focus upon gestural legib...

This paper tackles the representation of routes carried by a physical network infrastructure on a map. In particular, the paper examines the case where each route is represented by a separate colored linear symbol offset from the physical network segments and from other routes—as on public transit maps with bus routes offset from roads. In this study, the objective is to automate the placement ...

The paper discusses ongoing research on the effects of a signing avatar's modeling/rendering features on the perception of sign language animation. It reports a recent study that aimed to determine whether a character's visual style has an effect on how signing animated characters are perceived by viewers. The stimuli of the study were two polygonal characters presenting two different visual st...

A CAPTCHA which humans find to be highly legible and which is designed to resist automatic character–segmentation attacks is described. As first detailed in [BR05], these ‘ScatterType’ challenges are images of machine-print text whose characters have been pseudorandomly cut into pieces which have then been forced to drift apart. This scattering is designed to repel automatic segmentthen-recogni...

The legibility of standard Leroy alphanumeric symbols was compared with a new font, the Lincoln/MITRE (L/M) font. Legibility was tested by having human subjects attempt to identify the symbols when seen one at a time for a brief exposure period. The results showed the L/M font to be more legible than the standard Leroy. It is recommended that the two fonts be compared in a similar test on a TV ...

Most displays viewed in dark environments can easily cause dazzling glare and affect a viewer’s dark adaptation state (night vision). In previous work we showed that legibility could be improved and dark adaptation preserved in low-light environments by using a display design with a specially selected spectral light emission. We used long-wavelength light (red) that is easily visible to dayligh...
