I doubt it's for home use...
...as most blind people will pretty much know their way around, but could be useful in shops and other public buildings.
Fujitsu has helped develop an indoor support system that utilises impulse radio ultrawideband (UWB) tech to guide blind and partially sighted people around their homes. The system - co-created with Japan's National Institute of Information and Communications Technology - gives audio instructions on distances and directions to …
As said above, I'm not sure this is much cop for someone's own home. Any blind person not mentally capable of learning their way round their own home, is really going to struggle to use this app. On the other hand, it could be great for getting round public exhibitions, museums and the like.
Also, I presume you could have tracking devices on such things as keys, so they could be located when lost. Everyone loses their keys, it's just much more of a bugger to find them if you can't see.
I'm also a bit concerned about designing touch screen apps for blind people. My tests with a very smart, IT literate, blind 11 year old and my iPad were not at all successful. We tried it for an hour, and he's the best in his class at IT - although that should be no surprise considering he's got a normal and a Braille laptop, plus various other gizmos.
However, the RNIB recommend the iPhone, and he's getting an iPod Touch for his birthday. So my scepticism may be wrong. Also Android has the key advantage over iOS of allowing haptic feedback, which in my opinion is a killer application for blind people using touch screens.
Hooray for shiny tech. Making life easier. You can now get a £100 personal satnav to guide you to the shops, or tell you where you are on a bus, so you know when to get off. Still no household robot or flying car though...
Thanks to VoiceOver, the screen reader that comes included for free with iOS.
Android also has some screen reader solutions, but not all are free and none are as good as VoiceOver.
So no, tapping the destination on a touchscreen isn't a problem.
This could be very useful in train stations, airports, shopping malls, etc.
PS: I'm blind and use an iPhone and an iPad every day.
