Automatic recognition of the American sign language fingerspelling alphabet to assist people living with speech or hearing impairments

Abstract: Sign languages are natural languages used mostly by deaf and hard of hearing people. Different development opportunities for people with these disabilities are limited because of communication problems. The advances in technology to recognize signs and gestures will make computer supported interpretation of sign languages possible. There are more than 137 different sign languages around the world; therefore, a system that interprets them could be beneficial to all, especially to the Deaf Community. This paper presents a system based on hand tracking devices (Leap Motion and Intel RealSense), used for signs recognition. The system uses a Support Vector Machine for sign classification. Different evaluations of the system were performed with over 50 individuals; and remarkable recognition accuracy was achieved with selected signs (100% accuracy was achieved recognizing some signs). Furthermore, an exploration on the Leap Motion and the Intel RealSense potential as a hand tracking devices for sign language recognition using the American Sign Language fingerspelling alphabet was performed.

Verbal Art, Verbal Sign, Verbal Time

Abstract: The work of Roman Jakobson has long been recognized as central to debates in linguistics and literary theory. This book makes Jakobson's ideas, previously collected only in a monumental, seven-volume edition of his selected writings, readily available for the first time. It brings together eleven essays on topics of crucial importance to poetics and linguistics.

The Welsh Answering System

Abstract: The series publishes state-of-the-art work on core areas of linguistics across theoretical frameworks as well as studies that provide new insights by building bridges to neighbouring fields such as neuroscience and cognitive science. The series considers itself a forum for cutting-edge research based on solid empirical data on language in its various manifestations, including sign languages. It regards linguistic variation in its synchronic and diachronic dimensions as well as in its social contexts as important sources of insight for a better understanding of the design of linguistic systems and the ecology and evolution of language.

Visualizing science: the reception of powerpoint presentations

Abstract: Presentations with PowerPoint, made possible by digitalization, are another step towards more visualization in the history of science communication. This new genre of communicating scientific knowledge to an audience combines several semiotic sign systems and therefore can be analysed as a form of multimodal discourse that integrates pictures, text, design, etc. on the slides, as well as spoken language, gestures, acts of pointing, etc. by the speaker. This study approaches the problem of multimodal discourse – how meaning is constituted by the different modes – empirically from a recipient’s perspective. To reconstruct the meaning-making process, the authors apply eye tracking and other methods of reception research in real-life scenarios as well as in laboratory settings.

Performing Afro-Cuba: Image, Voice, Spectacle in the Making of Race and History

Abstract: Visitors to Cuba will notice that Afro-Cuban figures and references are everywhere: in popular music and folklore shows, paintings and dolls of Santeria saints in airport shops, and even restaurants with plantation themes. In Performing Afro-Cuba, Kristina Wirtz examines how the animation of Cuba's colonial past and African heritage through such figures and performances not only reflects but also shapes the Cuban experience of Blackness. She also investigates how this process operates at different spatial and temporal scales-from the immediate present to the imagined past, from the barrio to the socialist state. Wirtz analyzes a variety of performances and the ways they construct Cuban racial and historical imaginations. She offers a sophisticated view of performance as enacting diverse revolutionary ideals, religious notions, and racial identity politics, and she outlines how these concepts play out in the ongoing institutionalization of folklore as an official, even state-sponsored, category. Employing Bakhtin's concept of "chronotopes" - the semiotic construction of space-time - she examines the roles of voice, temporality, embodiment, imagery, and memory in the racializing process. The result is a deftly balanced study that marries racial studies, performance studies, anthropology, and semiotics to explore the nature of race as a cultural sign, one that is always in process, always shifting.
