Eight-dot Braille Historic Uses of Eight-dot Braille

Eight-dot Braille

There are numerous examples, both historic and modern, in which the six dots of the traditional braille cell have proven inadequate for a particular task. Enterprising inventors, teachers, and braille users have sought to expand the possibilities of the braille cell by increasing the number of dots from six to eight. These expansions have resulted in a cell that is two dots wide and four dots h...

An Experimental Approach in Conceptualizing Typographic Signals of Documents by Eight-Dot and Six-Dot Braille Code

The main research aim of the present study focuses on issues of reading comprehension, when users with blindness receive typographic metadata by touch through a braille display. Levels of reading comprehension are investigated by the use of 6-dot and 8-dot braille code in matched texts for the cases of bold and italic meta-data. The results indicated a slight superiority of the 8-dot braille co...

Patterns of Blind Users' Hand Movements - The Case of Typographic Signals of Documents Rendered by Eight-Dot and Six-Dot Braille Code

Design and Developing Methodology for 8-dot Braille Code Systems

Braille code, employing six embossed dots evenly arranged in rectangular letter spaces or cells, constitutes the dominant touch reading or typing system for the blind. Limited to 63 possible dot combinations per cell, there are a number of application examples, such as mathematics and sciences, and assistive technologies, such as braille displays, in which the 6-dot cell braille is extended to ...

Control Architecture Scalable Dedicated to Braille Panels for Displaying Information on Public Places

This paper proposes a control architecture for driving a panel Braille, that works as an aid in the reading of information by visually impaired people and also for applications for teaching Braille. To validate a prototype it was developed containing the control algorithm, which uses two techniques together: the conversion of characters in dot matrix in software and hardware multiplexing signal...
