Computer simulation of novel augmentative communications devices

Investigation into novel and useful communication aids for the deaf and nonverbal that are portable, cost-effective, and easy to operate has been hampered in the past by the lack of funding to develop prototype systems capable of satisfactorily testing new augmentative communication methodologies. A computer-based simulator was designed and clinically tested to allow the development and clinical trial of a wide selection of different portable communications devices. Suggested designs were then tested through repeated redesign cycles at minimal cost, allowing for the design and proving of multiple configurations and leading to an expedient series of final designs for actual prototype construction and field testing.<>
