At first glance, touchscreens don’t seem very suitable for people with a visual impairment. But if even Stevie Wonder is enthusiastic about the iPhone, it is clear that you can use a touchscreen phone even in poor visibility. Georgia Tech researchers are now going one step further. They have created a six-button prototype app with the name BrailleTouch. This allows you to enter letters according to the Braille script, which tells you which letter has been typed. You will receive immediate feedback whether the correct letter has been chosen. With the BrailleTouch app you can use the iPhone with the screen facing you.
