Scary side to green

May 14, 2008

The National Federation for the Blind brought to my attention an issue that I never even imagined could be a problem. Hybrid cars are very quiet. Visually impaired people use their hearing to avoid obstacles like cars. You can imagine the conundrum.

More quiet cars in the news

5/8/2008 1:31:00 PM

The dangers posed by silent vehicle technology continue to make headlines, and the general public is increasingly seeing the merits of the point of view of the National Federation of the Blind. Earlier this week, the Press-Enterprise published an excellent article about the problem. The article highlights continued scientific research about the perception of these vehicles by pedestrians, noting that a pedestrian may have as little as one second of warning in which to avoid an approaching hybrid car. Also this week, a Minnesota television station reported that a sighted eight-year-old cyclist had collided with a Toyota Prius that he did not hear. Thankfully, the child was not seriously injured. Jennifer Dunnam, the president of our Minnesota affiliate, was interviewed following this incident and explained the importance of vehicle sound to the blind and all other pedestrians. The television story has also been aired on CNN. In light of these developments, support for the Pedestrian Safety Enhancement Act of 2008 continues to grow, with twenty-five cosponsors having signed on to H.R. 5734 at the time of this writing. Representative Towns, the sponsor of the bill, has requested that Congressional hearings be held. The National Federation of the Blind is clearly requesting action that will benefit all pedestrians, and the logic of our argument is beyond dispute. VNB will continue to keep readers informed as support for safe vehicle technology continues to grow.

We have the technology

May 4, 2008

I did a little deeper research after the last post, and found that there seems to be more of a story than I originally thought with Rite Aid.

In 2000 the National Federation for the Blind, its D.C. affiliate, and several blind individuals sued Chevy Chase Bank, Rite Aid Corp. and Diebold over ATM accessibility issues.

According to the Americans with Disabilities Act, “instructions and all information for use be made accessible to, and independently usable by, persons with vision impairments.” The suit argued that while some of the defendants’ ATMs had Braille keypads and labels, the Braille was an “ineffective accommodation.”

Not all persons who are blind can read Braille,” explains Dr. Maurer, president of the National Federation for the Blind.

“Moreover, Braille keypads and labels are static. They do not provide accessible and independently usable, sequential, computer screen instructions to guide a blind customer through a bank transaction. As a result blind customers basically have little choice but to rely on others to do their banking for them.”

According to the NFB, the only effective means to make ATMs accessible to the blind is voice-guidance technology, which allows blind persons to hear step-by-step instructions. Voice-guidance technology is accessed by plugging personal headphones into a universal audio jack installed in the ATM or by using a telephone handset, also installed in the ATM.

The NFB has long been actively involved in promoting adaptive technologies for the blind so that blind people can live and work independently in today’s technology-dependent world.

As a side note, if you click on the link on the headline of the press release, it will take you to the source on NFB’s Web site. This is an outstanding page for the visually impaired. No navigation links, no complicated HTML, nothing that can trip up a screen reader. Just plain text. (more…)

Keep your PIN secure

May 4, 2008

I used to think it was a little silly when I would go to the drive-up ATM and there would be braille on the keypad. If someone needs braille to be able to use the keypad, should they really be driving?

But in reality, tactile keypads are extremely important for people with sight disabilities. With the increasing use of debit cards, sometimes scanning your card at the counter is the only option for payment. If the keypad is flat, a sight-impaired customer is forced to share their PIN with a stranger to complete the purchase. Having braille, or raised key eliminates this security risk and lets the customer do things on their own.

Rite Aid recently announced that it would be undertaking initiatives to improve its Web site to be compatible with the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (w3c) (www.w3.org/wai), and to install equipment with tactile keypads in all of its stores.

BBC on accessibility

April 28, 2008

Here’s a neat Youtube video from BBC about Web accessibility for the visually impaired. It has some interesting commentary on a study that determined that Web sites that adhere to accessibility standards are 34 percent easier for everyone to use. I had a little bit of an issue with the reporter talking about “the rest of us,” but the content was still good.

Around 4:10 there’s a discussion on the uses of Flash and CSS. I’ve never really been a fan of Flash when I use Web sites. I can’t stand things flying around willy-nilly without my control. But I think I’m going to have to do some research on the capabilities of Flash and CSS for accessibility
