Schools Shun Kindle Due to Lack of Accessibility to the Blind

Despite a function on the Kindle that reads text aloud, two universities and an advocacy group for the visually impaired adopted a staunch anti-Kindle stance Wednesday. According to an Associated Press report, the University of Wisconsin - Madison and Syracuse University won't invest in more electronic readers for college students because the audio feature is too difficult for a visually impaired person to activate. To engage the feature, a user must navigate a series of onscreen menus -- a process requiring a degree of sightedness that many of the United States' 1.3 million legally blind simply don't have.

A spokesman for the National Federation of the Blind applauded the schools' efforts. "These universities are saying, `Our policy is nondiscrimination, so we're not going to adopt a technology we know for sure discriminates against blind students'," Chris Danielsen told the Associated Press. With such strong words, it's no wonder that universities aren't ready to invest in the burgeoning e-book market. But Amazon.com, Inc. spokesman Drew Herdener said he hopes to change that. The company is working on improving the Kindle so that everybody can easily use it. Just how that'll happen, though, remains unclear.

For the record, we're rooting for the Kindle. Take it from former college students, the potential of having cheaper, digital textbooks is enough to make a starving student's mouth water. [From: Associated Press, via Newsvine]

Braille Touchscreen Could Bring iPhones to the Blind

Louis Braille, the man that invented the system of raised bumps that allow the blind to read, will celebrate his 200th birthday this year. His gift to the world, Braille, allows the sight-deficient to live relatively normal lives, reading elevator signs and ordering from the menu at certain restaurants. However, in the increasingly touchscreen-reliant, wireless world, the blind are at a loss. MP3 players, most cell phones, and computers are virtually useless (Braille-enabled computers are staggeringly expensive, and laptops can only read one line of text at a time).

While Yosi Bar-Cohen was staying the night in a hotel hosting a conference for the blind, the NASA researcher had an idea. Electroactive polymers (or EAPs), the same technology used in prosthetic limbs, could be fitted with sensors that would contract or move when exposed to voltage. If packed tightly enough, the EAP could serve as a translator for wireless devices. Dots would rise and fall depending on signals, turning the iPhone into a much more tactile experience.

Will 'Smart Cane' Render Seeing-Eye Dogs Obsolete?

Seeing-eye dogs may soon be looking for work as ordinary house pets, thanks to the development of a new "smart" walking cane. An engineering professor and his five students at Central Michigan University have developed a cane with a navigational system to aid the visually impaired.

According to Newsvine, the Smart Cane uses Radio Frequency Identification (RFID) technology (the same technology employed in those security tags on department stores' clothes) to "read" electronic tags placed on buildings. The cane, which contains an ultrasonic sensor, works in conjunction with a miniature navigational system carried inside a specially designed messenger bag. You can find images of the system here. A speaker located within the strap of the bag alerts the carrier of upcoming obstacles. (The students have also created a glove that vibrates in order to alert the hearing impaired.)

Researchers Develop Braille for Vibrating Touchscreen Devices


In braille, a character is made up of six dots laid out on a two by three matrix -- not something that can really be conveyed using capacitive touchscreen technology. Working with a Nokia 770 Internet Tablet, researchers in Finland have developed a method for piezoelectric touchscreen devices that uses a single pulse of intense vibration to convey a raised dot, and a longer vibration made up of several weaker pulses to represent a missing dot -- spelling out letters that can be easily read by touch. It took a while for volunteers to get used to this method, but once they had they were able to read a character in as little as 1.25 seconds. Now that they have letters down, the team is moving on to words and sentences -- with an eye towards developing text-to-braille software sometime in the future.

Stevie Wonder Says Touch-Screen Gadgets Exclude the Blind


Last week at CES, advocates for the blind -- music icon Stevie Wonder among them -- discussed the future of blind-accessible electronics, according to a Reuters report.

While Wonder cited an iPod and BlackBerry as gadgets he regularly uses and enjoys, he still finds plenty of room for improvement in regards to gadgets' becoming more accessible to blind consumers. "If you can take those few steps further, you can give us the excitement, the pleasure and the freedom of being a part of it," he explained.

But, with the current prevalence of touch screens in cutting-edge gadgets, those steps could prove to be difficult ones.

"Can I ski 60 miles an hour downhill? Yes. Use a flat panel microwave? No," laughed Mike May, President of Sendero Group. Blind himself, May's company offers accessible GPS units with specially-designed audio features.

Touch Sight Camera for the Blind Displays Photos Using Braille


Gadgets for the visually impaired are nothing new, but the Touch Sight camera is one of the most unique we've seen. Designed to be held against the forehead, the camera doesn't have an LCD, but instead displays a three-dimensional representation of the image on a built-in Braille screen and records three seconds of audio to assist users in locating and managing shots. Just a concept for now, but let's hope it makes it to market -- it seems like it'd be a fun toy for the sighted as well.

Web App Brings the Internet to the Blind


The Internet is supposed to be the great equalizer. Race, color, creed, class, and physical handicap are supposed to of no impediment on the Web. Unfortunately, the blind face great obstacles in getting online, especially from public computers, like those in a library or Internet cafe. Screen reading software is rarely installed on these PCs, and portable options are often prohibitively expensive.

A new Web app from a graduate student at the University of Washington aims to help break down these barriers by bringing screen reading technology to any Web-connected computer. If the user can navigate, or have someone navigate, to http://Webanywhere.cs.washington.edu/ they'll be able to launch an in-browser screen reader. The reader, called Web Anywhere, will work on any computer with any modern Web browser, such as Firefox or Internet Explorer 7.

The reader is still in early development and needs some tweaking, but it looks to be a potentially revolutionary tool for the blind. You can check out the video above for a demonstration of how the Web app works. It's nice to see someone using the powerful tools made available via the Web to build something that does more than let you share photos and 'poke' friends. [Source: Yahoo! News]

This Cell Phone Reads to the Blind

Reading Cellphone to Helps the BlindThe blind have long been criticizing our bills of various denominations thanks to their identical size, shape, and feel, which makes them impossible to tell apart for those with limited or no sight. Now, a potential solution is coming from a very common source: the camera phone in your pocket.

Computer software has long been able to identify characters or faces in pictures, meaning telling a $1 bill from a $100 bill is easy to do if you're a computer with the right programming. What hasn't been done on a large scale before is building this programming into smart phones with cameras and combining that with text-to-speech software. This enables the phone to verbalize what it's reading; a boon to those who would otherwise be unable to read the text.

The $2,100 smart-phone from the National Federation for the Blind and text-to-speech pioneer Ray Kurzweil is able to read currencies as well as just about any other printed words like menus or business directories. It's based on the Nokia N82 smart-phone, which can be used with AT&T and T-Mobile in the U.S. But, you won't be able to walk into your local AT&T store and buy one with this configuration. For a listing of retailers in the U.S. and abroad, plus some more details, head on over to the phone's page.
