UAB Researchers and ONCE pioneer a new Braille keyboard

13.03.2006



Researchers from the Universitat Autònoma de Barcelona and the Organización Nacional de Ciegos Españoles (ONCE) have developed a Braille keyboard for PCs that has some unique features. The keyboard provides more applications for blind people and is particularly useful for scientific texts and musical scores.

The new keyboard, which connects to the PC through the USB port, will make using a computer much easier for blind people who are accustomed to using Braille typewriters, since this is the first Braille keyboard to combine the function and movement keys of a conventional keyboard with eight Braille keys that allow the user to write in any language. Users can also select between a cumulative and a corrective writing mode. In the cumulative mode, the dots of a Braille symbol are indicated by pressing the keys one after another; in the corrective mode, this is done by pressing the necessary keys simultaneously.

The keyboard also provides the possibility to update its features as upgrades to the firmware (internal programmes that control the features) are developed in the future.



This new computer keyboard gives blind people enormous possibilities for working with mathematical formulae and scorewriter programmes. Until now, assistance was required from a sighted person for this kind of task.

The project, which began in March 2004 at the proposal of ONCE, was coordinated by the UAB Department of Microelectronics and Electronic Systems researcher Jordi Roig, who has been visually impaired for three years and is a member of ONCE. Teachers from the UAB School of Engineering and the UAB School of Computer Science in Sabadell participated in the research. The group is currently working on other projects that will enable blind people to work autonomously with technological applications. These projects include developing an automatic conversion tool for websites that are not currently accessible to blind people and creating a touchable screens that raises the information so that it can be felt.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
