success of effective communication of traffic sign messages to road users may not only relate to the user characteristics but also the signs themselves. The purpose of this experiment was to examine the cognitive design features of 120 Mainland China traffic signs. The features included familiarity, concreteness, simplicity, meaningfulness, and semantic closeness. Forty-one Hong Kong Chinese en...

IMPORTANCE OF THE STUDY. Currently, there is a paucity of evidence in the literature to show that handoff strategies improve the quality of handoff outcomes. Studies that show the usefulness and outcomes obtained from sign-outs may motivate junior clinicians, who have limited time to perform their clinical responsibilities, to support sign-out improvement efforts. OBJECTIVE. To test a research ...

The article describes the steps and results of a parallel research investigating e-health systems design and implementation for deaf people both in avatar and video technology. The application translates medical knowledge and concepts in deaf sign language for impaired users through an avatar. Two types of avatar technologies are taken into consideration: Video Avatar with recorded humans inter...

This paper introduces a new approach to user interface design and related areas, called algebraic semiotics. The approach is based on a notion of sign, which allows complex hierarchical structure and incorporates the insight (emphasized by Saussure) that signs come in systems, and should be studied at that level, rather than individually. A user interface can be considered as a representation o...

We describe the implementation and evaluation of a prototype American Sign Language (ASL) generation component that produces animations of ASL classifier predicates, some frequent and complex spatial phenomena in ASL that no previous generation system has produced. We discuss some challenges in evaluating ASL systems and present the results of a userbased evaluation study of our system. 1 Backg...

This paper presents the development of DeSIGN, an educational software application for those deaf students who are taught to communicate using American Sign Language (ASL). The software reinforces English vocabulary and ASL signs by providing two essential components of a tutor, lessons and tests. The current version was designed for 5 and 6 graders, whose literacy skills lag by a grade or more...

The Indus script is an undeciphered script of the ancient world. In spite of numerous attempts over several decades, the script has defied universally acceptable decipherment. In a recent series of papers (Yadav et al. 2010; Rao et al. 2009a, b; Yadav et al. 2008a, b) we have analysed the sequences of Indus signs which demonstrate presence of a rich syntax and logic in its structure. Here we fo...
