The paper reports a study that aimed to determine whether character's visual style has an effect on how signing avatars are perceived by viewers. The stimuli of the study were two polygonal characters that presented two different visual styles: stylized and realistic. Each character signed four sentences. Forty-seven participants with experience in American Sign Language (ASL) viewed the animat...

Legible motion — motion that communicates its intent to a human observer — is crucial for enabling seamless human-robot collaboration. In this paper, we propose a functional gradient optimization technique for autonomously generating legible motion. Our algorithm optimizes a legibility metric inspired by the psychology of action interpretation in humans, resulting in motion trajectories that pu...

It is imperative that primary care referrals are directed to the appropriate secondary care service. Patients presenting to a primary care physician with ENT conditions may require review in an Emergency Clinic. The latter clinics provide patients with rapid access to secondary care, for urgent, yet non-life-threatening conditions. In our department, we noticed that patients with conditions ina...

The purpose of this study was to determine the legibility of symbols formed from matrices which contained different numbers of dot elements. A set of alphanumeric symbols was constructed from each of the following dot matrices: 3x5, 5x7, 7x 11, and 9 x 15. The four symbol, sets were shown for identification to one group of operators under nearly optimal viewing conditions and to a second group ...

This article develops theoretical, algorithmic, perceptual, and interaction aspects of script legibility enhancement in the visible light spectrum for purpose scholarly editing papyri texts.

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 eno...
