A Special Phone App Helps Visually-impaired Use IPhone
Muhieddine El Kaissi's recently released iPhone, A Special Phone (iTunes link), which attempts to simplify the ability to dial without looking at the iPhone's touchscreen. Instead, it relies on other functionality of the phone, such as its accelerometer.
A Special Phone lets you set up a list of up to six contacts and then shake the phone a certain number of times to call that person. You shake the phone once for the first contact, twice for the second, and so on. The phone waits two seconds after the last detected shake and then automatically dials the specified contact.
