title: Personal communicator.
abstract: An assistive technology (AT) device was originally created for a young child who has difficulty communicating. The child is not able to talk and is not old enough to read yet. This rules out conventional communication devices that this child could use to communicate. A device was requested by the child's educator that would talk for the child. Originally it needed to be wristwatch size and able to visually cue the child so that the child would know what was going to be said. The project's first prototype was built by a senior design student. Although the basic features of the prototype functioned properly, it was not practical for day to day use. Originally a rebuild was requested by the educator but after further investigation it was decided that a new design was needed so that it could better cue the child. A new device was built using a high resolution graphic liquid crystal display (LCD), a voice recording chip and a microcontroller. The wristwatch size requirement was changed to meet available technology and the device was packaged to be used on a lanyard.
