Bernardine Dias 1 Acknowledgements We extend sincere and heartfelt gratitude to our partner, the Mathru Educational Trust for the Blind for mentoring and advising us throughout the duration of the iSTEP research internship. The authors would especially like to thank Ms. Muktha for giving us the opportunity to work with the Mathru School for the Blind. To all the students, teaching and non-teaching staff for their cooperation in working with us and providing us with a wealth of information that has assisted us in completing this research. In addition, we would also like to acknowledge Carnegie Mellon University for providing the academic infrastructure necessary to make our work possible. Abstract Assistive devices for the visually impaired are often prohibitively expensive for potential users in developing communities. This report describes field research aimed at developing and assessing assistive technology that is economically accessible and relevant to this population of visually impaired individuals. The work discussed was completed at the Mathru School for the Blind as part of the iSTEP internship program, which is organized by CMU’s TechBridgeWorld research group. Eight CMU student interns were recruited to work on this proJect over the course of nine weeks in Bangalore, India. In particular, this report details the development of two affordable technologies that aid in the teaching of braille writing to visually impaired children. These tools were created through an iterative process that incorporated user feedback at different stages of design and development. Findings from this research indicate that such assistive tools can enhance the education experience for visually impaired children in India, and can also facilitate the teaching process for their educators. In addition to technology development, at the request of the local partner institution, researchers conducted training sessions at the Mathru School for the Blind to enhance teachers’ computer literacy and skills. This report outlines the structure of these lessons for both sighted and blind individuals, as well as outcomes from the training sessions and feedback from participating teachers. 2 Table of Contents

  • Assessment of Options for Handling Full Unicode Character Encodings in MARC21 a Study for the Library of Congress
    1 Assessment of Options for Handling Full Unicode Character Encodings in MARC21 A Study for the Library of Congress Part 1: New Scripts Jack Cain Senior Consultant Trylus Computing, Toronto 1 Purpose This assessment intends to study the issues and make recommendations on the possible expansion of the character set repertoire for bibliographic records in MARC21 format. 1.1 “Encoding Scheme” vs. “Repertoire” An encoding scheme contains codes by which characters are represented in computer memory. These codes are organized according to a certain methodology called an encoding scheme. The list of all characters so encoded is referred to as the “repertoire” of characters in the given encoding schemes. For example, ASCII is one encoding scheme, perhaps the one best known to the average non-technical person in North America. “A”, “B”, & “C” are three characters in the repertoire of this encoding scheme. These three characters are assigned encodings 41, 42 & 43 in ASCII (expressed here in hexadecimal). 1.2 MARC8 "MARC8" is the term commonly used to refer both to the encoding scheme and its repertoire as used in MARC records up to 1998. The ‘8’ refers to the fact that, unlike Unicode which is a multi-byte per character code set, the MARC8 encoding scheme is principally made up of multiple one byte tables in which each character is encoded using a single 8 bit byte. (It also includes the EACC set which actually uses fixed length 3 bytes per character.) (For details on MARC8 and its specifications see: http://www.loc.gov/marc/.) MARC8 was introduced around 1968 and was initially limited to essentially Latin script only.

  • Deep Multitask Learning Through Soft Layer Ordering
    Published as a conference paper at ICLR 2018 BEYOND SHARED HIERARCHIES:DEEP MULTITASK LEARNING THROUGH SOFT LAYER ORDERING Elliot Meyerson & Risto Miikkulainen The University of Texas at Austin and Sentient Technologies, Inc. {ekm, risto}@cs.utexas.edu ABSTRACT Existing deep multitask learning (MTL) approaches align layers shared between tasks in a parallel ordering. Such an organization significantly constricts the types of shared structure that can be learned. The necessity of parallel ordering for deep MTL is first tested by comparing it with permuted ordering of shared layers. The results indicate that a flexible ordering can enable more effective sharing, thus motivating the development of a soft ordering approach, which learns how shared layers are applied in different ways for different tasks. Deep MTL with soft ordering outperforms parallel ordering methods across a series of domains. These results suggest that the power of deep MTL comes from learning highly general building blocks that can be assembled to meet the demands of each task. 1 INTRODUCTION In multitask learning (MTL) (Caruana, 1998), auxiliary data sets are harnessed to improve overall performance by exploiting regularities present across tasks. As deep learning has yielded state-of- the-art systems across a range of domains, there has been increased focus on developing deep MTL techniques. Such techniques have been applied across settings such as vision (Bilen and Vedaldi, 2016; 2017; Jou and Chang, 2016; Lu et al., 2017; Misra et al., 2016; Ranjan et al., 2016; Yang and Hospedales, 2017; Zhang et al., 2014), natural language (Collobert and Weston, 2008; Dong et al., 2015; Hashimoto et al., 2016; Liu et al., 2015a; Luong et al., 2016), speech (Huang et al., 2013; 2015; Seltzer and Droppo, 2013; Wu et al., 2015), and reinforcement learning (Devin et al., 2016; Fernando et al., 2017; Jaderberg et al., 2017; Rusu et al., 2016).

Parvathi reads the letters from the text file and converts each letter into Abstract: Braille transliteration of natural languages is Braille using Unicode mapping to Braille code. The Braille required for providing a better opportunity of learning and codes are mapped to corresponding Braille cells and then the creating opportunities of ceceity people. It allows a bigger Braille cells are organized into a standard Braille sheet. diaspora of non-blind teachers to have written communication However there is still no method which can be used to make with blind people. The present paper proposes a method of Braille transliteration of Handwritten and printed Odia characters the conversion of printed sheets into Odia Braille or automatically into Braille. The current work proposes a method of handwritten sheets into Odia Braille. This task has become Braille transliteration of Handwritten Odia text with industry physically realizable with considerably good accuracy applicable accuracy. The method first preprocesses the text and because of the design of high accuracy Optical character then segments it into characters and then uses an SVM classifier recognizer (OCR) for Odia language. The present paper trained on HOG features of Odia handwritten characters to proposes a method to automatically convert handwritten predict characters and maps the predicted printable character to characters into Braille, which can then further be used to its corresponding Braille with a very good accuracy. The method can further be used with text to speech engines to help the blind convert handwritten texts and printed texts into Braille.

  • A FORMAL COMPUTATIONAL ANALYSIS of INDIC SCRIPTS Richard Sproat University of Illinois at Urbana-Champaign
    A FORMAL COMPUTATIONAL ANALYSIS OF INDIC SCRIPTS Richard Sproat University of Illinois at Urbana-Champaign Introduction The Brahmi-derived Indic scripts occupy a special place in the study of writing systems. They are alphasyllabic scripts (Bright, 1996a) (though Daniels (1996) prefers the term abugida), meaning that they are basically segmental in that almost all segments are represented in the script, yet the fundamental organizing principle of the script is the (orthographic) syllable: crudely, an orthographic syllable — aks.ara — in an Indic script consists of a consonantal core consisting of one or more consonant symbols, with the vowels variously arranged around the core. The one exception to the principle that segments are repre- sented is the inherent vowel, usually a schwa or /a/-like phoneme: when the consonantal core is marked with no vowel, it is interpreted as hav- ing the inherent vowel (though phonological rules such as Hindi schwa- deletion (Ohala, 1983), can complicate this characterization). Brahmi-derived scripts are by no means the only scripts that are ba- sically segmental but have the syllable as an organizing principle: no- table other scripts are Ethiopic (Haile, 1996) and Korean Hankul (King, 1996); there have been claims that the latter is derived from Indic scripts, though King notes (page 219) that there have been “no less than ten different ‘origin theories’.”1 But Brahmi scripts are indubitably the most successful, spawning not only several scripts in the Indian sub- continent, but also spreading into Southeast Asia and spawning scripts such as Thai and Lao (Diller, 1996), and even arguably influencing the development in modern times of the Pahawh Hmong messianic script (Smalley, Vang, and Yang, 1990; Ratliff, 1996).

  • Braille Transliteration of Hindi Handwritten Texts Using Machine Learning for Character Recognition
    INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 8, ISSUE 10, OCTOBER 2019 ISSN 2277-8616 Braille Transliteration Of Hindi Handwritten Texts Using Machine Learning For Character Recognition Vinod Jha, K. Parvathi Abstract: Braille is a language of utmost importance for the upliftment of blind people. One of the problem with education of blind people is the unavailability of resources such as books etc. which are mostly in local languages being used by general people. Recently there have been lots of works done to automate the process of translating books in English, Arabic etc. into Braille as typing the whole book is very cumbersome. This paper is proposing an algorithm to convert any scanned handwritten document in Hındi to corresponding Braille. It uses Histogram of oriented gradients features of Hindi characters for matching in an SVM classifier. The scanned documents are first converted into a printable form and then transliterated to Braille using UTF-8 codes. Index Terms: Bharati Braille, OCR, HOG, Segmentation, SVM, Transliteration, UTF-8 —————————— —————————— 1. INTRODUCTION recognition (OBR) system is not as straight forward task as More than 285 million people have been reported visually it is for English as the basic characters in Indian scripts are impaired in the world but lack of proper education and a much more than 64 which cannot be represented by 64 lack of way of communication with the rest of the world Braille cells in 6 dot pattern. Therefore multiple Braille cells keep them void of opportunities and better life. With the are used to represent certain Indic language characters. recent advancements in technology it is possible to reduce this huge gap.
