Braillesketch: a Gesture-Based Text Input Method for People with Visual Impairments Mingzhe Li, Mingming Fan, Khai N
Session: Interaction Techniques and Frameworks ASSETS'17, Oct. 29–Nov. 1, 2017, Baltimore, MD, USA BrailleSketch: A Gesture-based Text Input Method for People with Visual Impairments Mingzhe Li, Mingming Fan, Khai N. Truong Department of Computer Science University of Toronto [email protected], [email protected], [email protected] ABSTRACT onscreen keyboard with screen reader software, such as Apple’s In this paper, we present BrailleSketch, a gesture-based text input VoiceOver. However, this approach results in a very low text method on touchscreen smartphones for people with visual entry speed [4]. Alternatively, people can use speech recognition impairments. To input a letter with BrailleSketch, a user simply software to input text at a much faster rate [3]. However, speaking sketches a gesture that passes through all dots in the in public places may not always be appropriate and can introduce corresponding Braille code for that letter. BrailleSketch allows privacy concerns. A growing body of research has been exploring users to place their fingers anywhere on the screen to begin a ways to leverage the user’s ability to perform touch and multi- gesture and draw the Braille code in many ways. To encourage touch gesture inputs on mobile devices. For example, BrailleTap users to type faster, BrailleSketch does not provide immediate [9], TypeInBraille [15], Perkinput [4], and BrailleEasy [23] enable letter-level audio feedback but instead provides word-level audio the user to type Braille by performing multiple taps sequentially to feedback. It uses an auto-correction algorithm to correct typing specify the dot codes for the desire letter—this can be time errors. -
Sign Language Typology Series
SIGN LANGUAGE TYPOLOGY SERIES The Sign Language Typology Series is dedicated to the comparative study of sign languages around the world. Individual or collective works that systematically explore typological variation across sign languages are the focus of this series, with particular emphasis on undocumented, underdescribed and endangered sign languages. The scope of the series primarily includes cross-linguistic studies of grammatical domains across a larger or smaller sample of sign languages, but also encompasses the study of individual sign languages from a typological perspective and comparison between signed and spoken languages in terms of language modality, as well as theoretical and methodological contributions to sign language typology.

Sign Language Endangerment and Linguistic Diversity Ben Braithwaite
RESEARCH REPORT Sign language endangerment and linguistic diversity Ben Braithwaite University of the West Indies at St. Augustine It has become increasingly clear that current threats to global linguistic diversity are not re - stricted to the loss of spoken languages. Signed languages are vulnerable to familiar patterns of language shift and the global spread of a few influential languages. But the ecologies of signed languages are also affected by genetics, social attitudes toward deafness, educational and public health policies, and a widespread modality chauvinism that views spoken languages as inherently superior or more desirable. This research report reviews what is known about sign language vi - tality and endangerment globally, and considers the responses from communities, governments, and linguists. It is striking how little attention has been paid to sign language vitality, endangerment, and re - vitalization, even as research on signed languages has occupied an increasingly prominent posi - tion in linguistic theory. It is time for linguists from a broader range of backgrounds to consider the causes, consequences, and appropriate responses to current threats to sign language diversity. In doing so, we must articulate more clearly the value of this diversity to the field of linguistics and the responsibilities the field has toward preserving it.* Keywords : language endangerment, language vitality, language documentation, signed languages 1. Introduction. Concerns about sign language endangerment are not new. Almost immediately after the invention of film, the US National Association of the Deaf began producing films to capture American Sign Language (ASL), motivated by a fear within the deaf community that their language was endangered (Schuchman 2004). -
What Sign Language Creation Teaches Us About Language Diane Brentari1∗ and Marie Coppola2,3
Focus Article What sign language creation teaches us about language Diane Brentari1∗ and Marie Coppola2,3 How do languages emerge? What are the necessary ingredients and circumstances that permit new languages to form? Various researchers within the disciplines of primatology, anthropology, psychology, and linguistics have offered different answers to this question depending on their perspective. Language acquisition, language evolution, primate communication, and the study of spoken varieties of pidgin and creoles address these issues, but in this article we describe a relatively new and important area that contributes to our understanding of language creation and emergence. Three types of communication systems that use the hands and body to communicate will be the focus of this article: gesture, homesign systems, and sign languages. The focus of this article is to explain why mapping the path from gesture to homesign to sign language has become an important research topic for understanding language emergence, not only for the field of sign languages, but also for language in general. © 2012 John Wiley & Sons, Ltd.

Texture Perception in Sighted and Blind Observers
Perception & Psychophysics /989. 45 (I). 49-54 Texture perception in sighted and blind observers MORTON A. HELLER Winston-Salem State University, Winston-Salem, North Carolina The purpose of the present study was to evaluate the utility of visual imagery for texture per ception. In Experiment 1, sighted, early-blind, and late-blind observers made relative smooth ness judgments of abrasive surfaces using active or passive touch. In Experiment 2, subjects com pared vision and touch in the accuracy of smoothness detection, using a broad range of textures, including very fine surfaces. No differences appeared between the sighted and the blind, and it did not matter iftouch were active or passive. Vision and touch showed similar performance with relatively coarse textures, but touch was superior to vision for much finer surface textures. The results were consistent with the notion that visual coding oftactual stimuli is not advantageous (or necessary) for texture perception, since touch may hold advantages for the detection of the smoothness of surfaces. The present study was directed toward an evaluation subjected to tilt. Although the benefits of visual imagery ofthe necessity ofvisual imagery for texture perception. are likely to be pronounced in form perception, it is not Some researchers have claimed that visual images are known whether visualization aids in texture judgments. necessary for tactual perception of form by sighted in One would expect that observers would tend to visual dividuals (e.g., Pick, 1974).

Interpretation of Swedish Sign Language Using Convolutional Neural Networks and Transfer Learning
DEGREE PROJECT IN INFORMATION AND COMMUNICATION TECHNOLOGY, FIRST CYCLE, 15 CREDITS STOCKHOLM, SWEDEN 2020 Interpretation of Swedish Sign Language using Convolutional Neural Networks and Transfer Learning Gustaf Halvardsson & Johanna Peterson KTH ROYAL INSTITUTE OF TECHNOLOGY ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Authors Gustaf Halvardsson & Johanna Peterson [email protected] & [email protected] The School of Electrical Engineering and Computer Science KTH Royal Institute of Technology Place for Project KTH Royal Institute of Technology & Prevas AB Stockholm, Sweden Examiner Benoit Baudry - KTH Royal Institute of Technology Supervisors César Soto Valero - KTH Royal Institute of Technology Maria Månsson - Prevas AB ii Abstract The automatic interpretation of signs of a sign language involves image recognition. An appropriate approach for this task is to use Deep Learning, and in particular, Convolutional Neural Networks. This method typically needs large amounts of data to be able to perform well. Transfer learning could be a feasible approach to achieve high accuracy despite using a small data set. The hypothesis of this thesis is to test if transfer learning works well to interpret the hand alphabet of the Swedish Sign Language. The goal of the project is to implement a model that can interpret signs, as well as to build a user-friendly web application for this purpose. The final testing accuracy of the model is 85%. Since this accuracy is comparable to those received in other studies, the project’s hypothesis is shown to be supported. The final network is based on the pre-trained model InceptionV3 with five frozen layers, and the optimization algorithm mini-batch gradient descent with a batch size of 32, and a step-size factor of 1.2. -

Chapter 2 Sign Language Types
Chapter 2 Sign language types This chapter defines four different sign language types, based on the infor- mation available in the respective sources. Before introducing the types of sign languages, I first report on the diachronic developments in the field of typological sign language research that gave rise to the distinction of the various sign language types. Sign language research started about five decades ago in the United States of America mainly due to the pioneering work of Stokoe (2005 [1960]), Klima and Bellugi (1979), and Poizner, Klima and Bellugi (1987) on American Sign Language (ASL). Gradually linguists in other countries, mainly in Europe, became interested in sign language research and started analyzing European sign languages e.g. British Sign Language (BSL), Swedish Sign Language (SSL), Sign Language of the Netherlands (NGT) and German Sign Language (DGS). Most of the in-depth linguistic descrip- tions have been based on Western sign languages. Therefore, it has long been assumed that some fundamental levels of linguistic structure, such as spatial morphology and syntax, operate identically in all sign languages. Recent studies, however, have discovered some important variations in spatial organization in some previously unknown sign languages (Washabaugh, 1986; Nyst, 2007; Marsaja, 2008; Padden, Meir, Aronoff, & Sandler, 2010). In the context of growing interest in non-Western sign languages towards the end of the 1990s and more recently, there have been efforts towards developing a typology of sign languages (Zeshan, 2004ab, 2008, 2011b; Schuit, Baker, & Pfau, 2011). Although it has been repeatedly emphasized in the literature that the sign language research still has too little data on sign languages other than those of national deaf communities, based in Western or Asian cultures (Zeshan, 2008). -
