There are many technical appliances that help blind people in their daily routines. For example colour scanners to help select clothes, portable barcode scanners that help with shopping and calculators with voice output. However, these devices are produced in very small quantities and are therefore extremely expensive. A smartphone could replace all these devices. However, the problem is that a touchscreen is the least accessible interface for a blind person to use. The Keyphone seeks to make smartphones more accessible to blind people while keeping the costs as low as possible by extending the interface of a normal mass-produced smartphone.
