Abstract
In general, the conversation through telephones has become an important part of daily life. However, many physically disabled persons who have insufficient manual dexterity to operate a telephone keypad can not benefit from use of such a telephone communication system. The object of the work presented in the article is to design a simple and inexpensive telephone dialing aid, which allows disabled persons to dial telephones themselves. The dialing aid consists of four main blocks: an input unit, a microprocessor control unit, a keypad triggering circuit unit, and an LED output display unit. Ten persons were asked to evaluate a prototype of the dialing aid. On average, it took 107.1 seconds to make a 8-digit phone call.
