Enabling two women with blindness and additional disabilities to make phone calls independently via a computer-aided telephone system.

Objective: To assess whether two women with blindness and additional disabilities could make independent phone calls through a computer-aided telephone system.
Method: For each participant, the study involved an ABAB design, in which the A represented baseline phases and the B represented intervention phases with the special telephone system (involving among others a net-book computer with specific software, a global system for mobile communication modem and a microswitch).
Results: Both participants learned to use the system and made phone calls independently to a variety of partners such as family members, friends and staff personnel.
Conclusion: The system assessed in this study might represent a useful means for enabling persons with blindness and additional disabilities to manage phone calls on their own.
