Accessible Cellular Telephones

Project Overview

The Hands Free Dialer was designed for people with significant physical disabilities and provided the means to access a Nokia wireless handset, mounted on a wheelchair. Those individuals with no functional hand dexterity to press the handset keys could access the phone via a single, external ability switch. The optional audio headset boom came with an integrated switch built into the ear-piece for head control. The switch controlled a sequential scan through various telephone-control options that appeared on the handset’s display. The scan speed and audio feedback were user selectable.
