Rotating-Wheel Braille Display for Continuous Refreshable Braille
2000年5月1日 · Smaller displays (e.g. 8-character) are available, but require the user to move a finger back and forth, raising issues of convenience and repetitive stress injuries.Our objective in undertaking this project was to find a new approach to Braille display design that would significantly lower cost and improve reliability, and still provide a ...
This is done by putting the Braille text on a rotating wheel or disc. Instead of moving fingers over a motionless line of text, the user puts one or more fingers against the wheel, and the Braille text moves underneath the finger, producing a sensation of motion, providing sufficient stimulus for the sensors in the fingertips, and
Current Developments in Refreshable Braille Display Technology
The National Federation of the Blind (NFB), funded by the National Institute of Standards and Technology (NIST), has developed a prototype for a refreshable Braille device that uses rotating wheel technology to reduce the number of actuators needed for a single-line, 80-character display to 3-to-4 actuators.
49.2: Rotating-Wheel Braille Display for Continuous
2000年5月1日 · This paper presents the design of a horizontal rotating wheel Braille display, using the advantages of a fast prototyping platform for power electronics (FPP).
Refreshable braille display - Wikipedia
A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Visually impaired computer users who cannot use a standard computer monitor can use it …
49.2: Rotating‐Wheel Braille Display for Continuous Refreshable Braille
2000年5月1日 · A novel wheel-based design addresses reliability issues, and provides continuous Braille text with many-fold reduction in cost. Refreshable Braille provides a critical path to display accessibility. High cost and reliability issues severely limit the market for existing Braille displays.
Rotating-Wheel Braille Display Provides Low-Cost Accessibility …
2000年9月5日 · We have developed a new technology to reduce the cost of Braille-based information accessibility. Millions of blind and visually impaired people in the US (and far higher numbers worldwide) need some form of non-visual access to information. The widespread use of Braille displays has been limited primarily by cost and reliability issues.

A passive and scalable magnetic mechanism for braille cursor, an ...
2020年6月12日 · In this work, we present the design and experimental analysis of a novel mechanism for a refreshable braille display (RBD). It implements a single actuated slider for refreshing braille cells composed of simple and passive ferromagnetic pins. The approach potentially decouples the cost of the final device from the number of braille cells and pins.
NIST University's wheel architecture concept for a rotating …
The proliferation of low-cost braille displays raises new possibilities for adult braille learners, with dots of greater height than standard paper braille, potentially benefitting older...
