Now this is pretty cool. Even though it's only a concept at this point, the Silicon Touch iPhone case is an accessory for your iPhone that's meant for those who are visually impaired. And the real plus side here is that it doesn't take away any of the iPhone's functionality.
The case would work with an accompanying iPhone app, allowing users to feel what they type and what icons they're pressing. Multi-touch functions are not sacrificed, either, so all of your gestures and swipes will still be recognized.
Why, oh why is it that the coolest items are always just concepts? Despite this question that I always ask, we don't know much else about the Silicon Touch iPhone case. Hopefully, if there is a big enough market demand for it, it would eventually hit production.
