Sci-Tech: BLITAB tactile tablet for the blind and visually impaired

The touch tablet computer display for the blind is one of those devices that I was sure must already exist in our high-tech world but in fact it does not. However, BLITAB®  of Austria is not only bringing one to market but at a reasonable price, something that is fairly uncommon for such aids for the handicapped: This $500 Tablet Brings Words to Blind Users’ Fingertips – Technology Review   

BLITAB describes the device as follows:

BLITAB® is the World’s first tactile tablet for blind and visually impaired people. BLITAB® is a next curve Braille device for Braille reading and writing that displays one whole page Braille text at once, without any mechanical elements. It is like an e-book which instead of using a screen displays small physical bubbles. For the first time our users can have an overview of a whole document. The new developed technology used in the BLITAB® tablet provides an opportunity for an affordable, 100x better solution, disrupting a market that has no innovations in the last 40 years.

We developed a multi-line Braille tablet that delivers real-time content to people with visual impairments. BLITAB® offers completely new user experience for Braille and non-Braille readers via touch navigation, text-to-speech output and Perkins-style keyboard application. It allows a direct converting of any text file into Braille from USB sticks, Internet and obtaining information via NFC tags. BLITAB® is not just a tablet, it is a platform for all existing and future software applications for blind readers. So we do not compete, we integrate and collaborate.

 

Video: “How Stars Form” – Christopher McKee

A SETI Institute seminar by Christopher McKee on how stars are made:

Stars are the atoms of the universe. The process by which stars form is at the nexus of astrophysics since they are believed to be responsible for the re-ionization of the universe, they created the heavy elements, they play a central role in the formation and evolution of galaxies, and their formation naturally leads to the formation of planets. Whereas early work on star formation was based on the assumption that it is a quiescent process, it is now believed that turbulence plays a dominant role. In this overview, I shall discuss the evolution of our understanding of how stars form and current ideas about the stellar initial mass function, the rate of star formation, the formation of massive stars, the role of magnetic fields, and the formation of the first stars.

Sci-Tech: Boston Dynamics shows off latest robo-beasts

Robot maker Boston Dynamics is best known for its four legged mechanical wonders that travel with animal-like coordination. Here is a video posted by Steve Jurvetson from conference where Marc Raibert, founder of Boston Dynamics, describes clips of some of their robots and then brings a four legged robot onto the stage. At 3:45 or so into the video he shows a video of a new two-wheeled robot, their first with wheels.

Sci-Tech: Hyperloop competition at SpaceX underway. Live webcast.

The university Hyperloop competition at the SpaceX HQ in Hawthorne, California is underway. Live webcast is available at www.spacex.com/hyperloop. See also Hyperloop live report – Daily Breeze | Facebook.

30 university teams are participating in the contest. The track is a hollow tube about three-quarter-mile (1.2 km) long and pumped down to low pressure. Each of the teams will run their pod vehicle down the pod. The pod performance will be evaluated on acceleration, speed, braking, etc.

[ Update: Reports on the competition results:

From Alan Boyle:

Here’s who won the Hyperloop competition’s awards:

    • Fastest team: WARR Hyperloop.
    • Highest overall score: Delft Hyperloop.
    • Safety and reliability award: MIT Hyperloop.
    • Performance and operations: University of Maryland. Honorable mention: Virginia Tech, Purdue, Hyperlift (St. John’s High School, Texas).
    • Performance in flight: WARR Hyperloop.
    • Innovation: Badgerloop (University of Wisconsin at Madison) and Team rLoop (the contest’s only non-student team, organized through Reddit). Honorable mention: VicHyper (Royal Melbourne Institute of Technology, Australia).
    • Design and construction: The top 10, from 1 to 10, are Delft, WARR, MIT, Virginia Tech, University of Maryland, University of Washington, Purdue, Carnegie Mellon University, Hyperlift, Keio Alpha.
