Weekly digest

Happy holidays everyone
I have tons of materials i would like to share with readers on tech helping blind people, but have limited time, so i decided to write weekly digest to cover most interesting articles.

After quite holiday time lets start with some fun.

Blind gamer Terry Garrett is completing 3d game – legends of Zelda. Really amazing and nice to see that people like Garrett can enjoy things we think are inaccessible for visually impaired people. He finishe Oddworld: Abe’s Oddysee before Zelda, which was insane complex game for me, and i was not able to get to the games end. So Terry looks like real hardcore gamer.
He is using stereo-speakers that help him to orient in the game.

Make sure to check more videos on his youtube channel

Now back to tech. Nowadays almost all IT giants have their own solution on picture recognition. Some of them are even developing these solutions not only for commercial purposes, but actually to help blind people to “see” – i wrote a little bout this initiatives in previous blog post Teaching machine to see and recognize.

Fortunately there are some number of mobile solutions on the market made by enthusiast and researchers.

Joseph Paul Cohen, a Ph.D Candidate at the University of Massachusetts Boston build free android app called BlindTool. App can identify an object after you point your phone on it within seconds

More info on how it work can be foundhere

Another cool app called Bemyeyes is connecting volunteers with blind people, establishing video connection between them in case blind need some urgent help with “seeing” something. For visually impaired people, small domestic tasks can be challenging, and app can be in handy in this case.

Latest mobile OS have strong accessibility features, more and more apps coming to market to help blind people, but what of visually impaired person doesnt know how to use smartphones?

Some interesting news from Switzerland, which have now approximately 325,000 blind or visually impaired people. There is a school teaching bout 250 visually impaired people on how to use iphones to make their life easier.


Hacking kinect

IF you are really smart in tech, creative and want to solve real problem for people, u can find out that building product or tech will not cost you a fortune.

In 2011 several different groups of people were prototyping navigation assistant for visually impaired people using hacked xbox kinect.

Kinect is using infrared sensors to detect motion and distance to objects.

You can read more on how it works http://www.jameco.com/jameco/workshop/howitworks/xboxkinect.html.

And this tech appeared to be real handy to detect obstacles for blind people, all u need some computer to track the information and signaling system to warn the user.

Audio channel is not the best way to inform blind people during the navigation. In this case the whole sense is used for just one task, and people are loosing the way to get more info on surroundings, which really is creating more problems then solving.

So one talented team of enthusiasts went even further with kinect concept and have created Belly-mounted tactile matrix to worn user about approaching obstacles.
“Each tactile pixel is disassembled electromagnetic relay much like this with a curved paper-clip attached. Voltage is applied periodically so that pixel prods person several times a second. The more frequency is, the closer is the object under that pixel. Depth perception made that way is not very accurate, but even non-trained person could easily distinguish ‘very close’ from ‘about one meter’ from ‘about three metres’.”

Project won second place at Russian Imagine Cup at 2011.

Teaching machines to see and recognize

Tech giants Facebook and Google are working hard on improving machine learning capabilities. They want machine to understand pictures like human do it.


They have different purpose of their research – google is using this technology to power their Photos app, Facebook is improving accessibility of their platform.

Both tech can be in handy for visually impaired people.

Here is the latest example from facebook

Both companies are using neuron networks. And whats interesting there, that with evolving of technology, blind people will be able to get real time audio description of surroundings using onhead cam for example. Of course pushing all the info on whats near you through audio doesnt make sense, though using assistant and asking question can do the work.

Imaging this concept but using camera on your head instead of steady image from your facebook feed.

Using Dash cam and image analyze your smartphone will be able to predict the obstacles while you move, where there is a puddle or pole ahead and you need to turn to avoid it.

Hello Folks

My name is Sergiy Voronov. I am UX/UI guy, working for UK startup www.clinpal.com. In this blog i will be writing bout the topic that excites me the most now – user experience for blind people.

Nowadays 285 million people are estimated to be visually impaired worldwide: 39 million are blind and 246 have low vision.

Due to tech bum (smartphones with gps and audio, bluetooth beacons, Braille smartwatches ,  intelligent personal assistants and other cool gadgets) life of blind people can be little easier.
