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...

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 ...

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...

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 ...

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...

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...
