DOI: https://doi.org/10.5281/zenodo.290662 The Unicode Cookbook for Linguists Managing writing systems using orthography profiles Steven Moran & Michael Cysouw Change dedication in localmetadata.tex Preface This text is meant as a practical guide for linguists, and programmers, whowork with data in multilingual computational environments. We introduce the basic concepts needed to understand how writing systems and character encodings function, and how they work together. The intersection of the Unicode Standard and the International Phonetic Al- phabet is often not met without frustration by users. Nevertheless, thetwo standards have provided language researchers with a consistent computational architecture needed to process, publish and analyze data from many different languages. We bring to light common, but not always transparent, pitfalls that researchers face when working with Unicode and IPA. Our research uses quantitative methods to compare languages and uncover and clarify their phylogenetic relations. However, the majority of lexical data available from the world’s languages is in author- or document-specific orthogra- phies. -
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. -

Haptiread: Reading Braille As Mid-Air Haptic Information
HaptiRead: Reading Braille as Mid-Air Haptic Information Viktorija Paneva Sofia Seinfeld Michael Kraiczi Jörg Müller University of Bayreuth, Germany {viktorija.paneva, sofia.seinfeld, michael.kraiczi, joerg.mueller}@uni-bayreuth.de Figure 1. With HaptiRead we evaluate for the first time the possibility of presenting Braille information as touchless haptic stimulation using ultrasonic mid-air haptic technology. We present three different methods of generating the haptic stimulation: Constant, Point-by-Point and Row-by-Row. (a) depicts the standard ordering of cells in a Braille character, and (b) shows how the character in (a) is displayed by the three proposed methods. HaptiRead delivers the information directly to the user, through their palm, in an unobtrusive manner. Thus the haptic display is particularly suitable for messages communicated in public, e.g. reading the departure time of the next bus at the bus stop (c).

Braille in Mathematics Education
Masters Thesis Information Sciences Radboud University Nijmegen Braille in Mathematics Education Marc Bitter April 4, 2013 Supervisors IK183 Prof.Dr.Ir. Theo van der Weide Dr. Henny van der Meijden Abstract This research project aimed to make improvements to the way blind learners in the Netherlands use mathematics in an educational context. As part of this research, con- textual research in the field of cognition, braille, education, and mathematics was con- ducted. In order to compare representations of mathematics in braille, various braille codes were compared according to set criteria. Finally, four Dutch mathematics curricula were compared in terms of cognitive complexity of the mathematical formulas required for the respective curriculum. For this research, two main research methods were used. A literature study was conducted for contextual information regarding cognitive aspects, historic information on braille, and the education system in the Netherlands. Interviews with experts in the field of mathematics education and braille were held to relate the contextual findings to practical issues, and to understand why certain decisions were made in the past. The main finding in terms of cognitive aspects, involves the limitation of tactile and auditory senses and the impact these limitations have on textual aspects of mathematics. Besides graphical content, the representation of mathematical formulas was found to be extremely difficult for blind learners. There are two main ways to express mathematics in braille: using a dedicated braille code containing braille-specific symbols, or using a linear translation of a pseudo-code into braille. Pseudo-codes allow for reading and producing by sighted users as well as blind users, and are the main approach for providing braille material to blind learners in the Netherlands. -
