BrailleTouch App: Helps blind to send text messages

Researchers at Georgia Tech produced the app - to be made available on Apple and Android devices - based on the Braille writing system.

It is claimed typing with the app is up to six times faster than existing methods for texting without sight.

Access to technology for the visually-impaired is a growing issue due to the proliferation of touchscreens.

Experts say currently available tools, such as Apple's Voiceover technology, are functional but too slow to be used effectively.

Brailletouch, which the team hope to release in the next couple of weeks, uses a system that is controlled with six fingers and, crucially, does not require any movement of the hands.

"Users who know how to type Braille well never move their hands," explained Mario Romero, lead researcher on the project.

"When users hold the phone they hold the phone with the screen facing away from them in landscape mode.

"They wrap the index, middle and ring finger in each hand around the phone.

"It's not like the Qwerty keyboard where you move up and down. That's why this thing works - we can get away with only six keys."

"This is not for texting and driving” Mario Romero Lead researcher

Eyes-free kit

Brailletouch will be free and open-source, its makers say, and it is hoped it could even become an "eyes-free" solution for fully-sighted people who want to text while visually pre-occupied with something else.

"Learning to type Braille is learning to memorise where the the dots fall," Mr Romero said.

"It took me and my colleagues a few hours to memorise things so we could start typing at around 10 words per minute. It's not something that takes years.

"We're hoping that, if not Braille, a similar system may solve the issue of having too many keys that are too small that force everybody to look at the screen when they're typing."

However, Mr Romero was quick to dampen any possible hopes that the software could be used to text while behind the wheel.

"They need to concentrate on what they're doing. This is not for texting and driving," he said.

'Truly blind'
Mr Romero highlighted a growing anxiety shared among the blind community that the widespread adoption of touchscreens for many machines and devices is making them "truly blind".

"There is extreme concern about this new trend.

"A lot of equipment today - from copying machines to machines at the gym - is all coming with touch screens."

He added that while research into tactile screens, which give users feedback by moulding, is taking place, we are still some way from having touchscreens which adequately cater for the visually-impaired.

"Blind people say I 'see' things with my fingers," Mr Romero said.

"But on touchscreens they are truly blind."

Google glasses: Streaming info to your eyeballs

When smartphones came out, it seemed like a leap in convenience to be able to carry important information on us at all times, instead of leaving it with our computers.

But soon, it may seem onerous to reach for your phone, turn it on and find the right app to get a piece of information, when you could instead just wear a pair of glasses that directly stream information to your eyeballs.

By year’s end, Google is set to release glasses that do exactly that in real time, so you won’t constantly have to reach into your purse or pocket.

The glasses, which will be Android-based, will cost about as much as a smartphone ($250-$600) and feature a 3G or 4G data connection and GPS and motion sensors and, of course, they’ll sport a screen a few inches away from the eye.

Here are some other key features:

• A unique navigation system that scrolls and clicks with a tilt of the head: Seth Weintraub, a 9 to 5 Google blogger who broke the story says, “We are told it is very quick to learn and once the user is adept at navigation, it becomes second nature and almost indistinguishable to outside users.”
• A low-resolution built-in camera: It will monitor the world in real time and overlay relevant information about the location, nearby buildings and friends who happen to be in the area.
• The ability to send data to the cloud: Then, the wearer can tap into services such as Google Latitude to share his/her location, Google Goggles to search images and figure out what he/she is looking at, Google Maps to find out what else is nearby, and to check in to places.

They’ll look like Oakley Thumps (pictured above), and Google expects that users won’t wear them all the time but only when they want the augmented reality view.

The glasses are being developed at the Google X offices, a secret lab that works on futuristic projects such as robots and space elevators.

"Internally, the Google X team has been actively discussing the privacy implications of the glasses and the company wants to ensure that people know if they are being recorded by someone wearing a pair of glasses with a built-in camera."

For now, Google isn’t yet thinking about developing business models from the glasses, but will wait to see if the glasses take off first.

Meanwhile, Apple is also reportedly working on wearable computing, the inform of a computer that straps around the wrist.

Meanwhile, Google is said to be building a $120 million electronics facility for testing “precision optical technology.”

Vision through Retina Implants

The Argus II is a minuscule artificial eye that attaches to the retina via 60 electrodes. Stephen Rose, chief research officer at the Foundation Fighting Blindness, says it has “great potential for giving vision to people with the most advanced retinal disease.” With the second phase of human trials underway, expect production models this year.
