Objective: To determine whether doctors have worse handwriting than other health professionals. Design: Comparison of handwriting samples collected prospectively in a standardised 10 seconds' task. Setting: Courses on quality improvement. Subjects: 209 health care professionals attending the courses, including 82 doctors. Main outcome measures: Legibility rated on a four-point scale by four rat...

This article presents an analysis of handwritten signature dynamics belonging to two authentication groups, namely genuine and forged signature samples. Genuine signatures are initially classified based on their relative size, graphical complexity, and legibility as perceived by human examiners. A pool of dynamic features is then extracted for each signature sample in the two groups. A two-way ...

Modern digital typography often has to contend with output devices such as workstation screens and laser-printers which have a much lower resolution than metal type or phototypesetter machines. In this paper we present results of some legibility investigations in which volunteers were asked to read laser-printed and photocopied material produced in three different typefaces. Two of these faces ...

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...

The goal of the study reported in the paper was to determine whether rendering style (non-photorealistic versus realistic) has an effect on perception of American Sign Language (ASL) finger spelling animations. Sixty-nine (69) subjects participated in the experiment; all subjects were ASL users. The participants were asked to watch forty (40) sign language animation clips representing twenty (2...

The goal of the study reported in the paper was to determine whether Ambient Occlusion Shading (AOS) has a perception of American Sign Language (ASL) finger spelling animations. Seventy-one (71) subjects participated in the study; all subjects were fluent in ASL. The participants were asked to watch forty (40) sign language animation clips representing twenty (20) finger spelled words. Twenty (...

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...
