Introduction 1.1 The Welsh Government commissioned the University of Birmingham to undertake a rapid evidence assessment (REA) into the extent to which interventions to support learners affected by vision impairment are effective. The purpose of the review is to facilitate the planning and delivery of early, timely and effective interventions to support children and young people with vision impairment. 1.2 The Additional Learning Needs and Education Tribunal (Wales) Act (the Act) received royal assent in January 2018. The Act introduces a new additional learning system, which has three overarching objectives: a unified legislative framework to support all children and young people with additional learning needs (ALN) from birth up to the age of 25, where they remain in education an integrated, collaborative process of assessment, planning and monitoring which facilitates early, timely and effective interventions a fair and transparent system for providing information and advice, and for resolving concerns and appeals. 1.3 The Act provides for a single plan – the individual development plan

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.

In this work, we present the design and development of a math braille-codes' repository named BrailleMathCodes. It aims to constitute a knowledge base as well as a search engine for both students who need to find a specific symbol code and the editors who produce accessible STEM educational content or, in general, the learner of math braille notation. After compiling a set of mathematical braille codes used worldwide in a database, we assigned the corresponding Unicode representation, when applicable, matched each math braille code with its LaTeX equivalent, and forwarded with Presentation MathML. Every math symbol is accompanied with a characteristic example in MathML and Nemeth. The BrailleMathCodes repository was designed following the Web Content Accessibility Guidelines. Users or learners of any code, both sighted and blind, can search for a term and read how it is rendered in various codes. The repository was implemented as a dynamic e-commerce website using Joomla! and VirtueMart. 1 Introduction Braille constitutes a tactile writing system used by people who are visually impaired.

  • 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).

Assistive technology has converted learning into an approachable good for them. Based on the literature review, braille turned out the most effective assistive device that promotes deafblind (DB) children’s literacy. However, education without human contribution cannot operate properly. For that reason, teachers play a vital role in children’s learning development and can act as the mediators of the provided knowledge. The educational personnel has to bear in mind that every DB child has unique necessities. Consequently, it is imperative need to teach them the suitable combination of methods and techniques consolidated with their knowledge and experience. This research study will employ the methodology of qualitative research as well as the method of semi-structured interviews with teachers of DB students, in order to discover efficient strategies of teaching braille that could build children’s literacy in the school environment. Keywords: deafblindness, assistive technology, braille literacy, teaching strategies 1. Introduction Howe initially referred to deafblindness in 1648 when he described how a deaf and blind doctor (John Bulwar) taught to speak (Das and Mishra, n.d.). An example of a talented DB individual is the renowned Helen Keller, who raised awareness and encouraged many others with visual and hearing impairments (Parker, McGinnity and Bruce, 2011).

This material may be downloaded and printed, but not altered or sold. The mission and purpose of the Braille Authority of North America are to assure literacy for tactile readers through the standardization of braille and/or tactile graphics. BANA promotes and facilitates the use, teaching, and production of braille. It publishes rules, interprets, and renders opinions pertaining to braille in all existing codes. It deals with codes now in existence or to be developed in the future, in collaboration with other countries using English braille. In exercising its function and authority, BANA considers the effects of its decisions on other existing braille codes and formats; the ease of production by various methods; and acceptability to readers.
