ABSTRACT:
A communication aid comprising a housing and a series of visual display cards bearing illustrations of objects are mounted in side-by-side relation on the front face of the housing. A group of lights are also disposed on the front face, each light being associated with a card. A group of physical objects corresponding to the objects depicted on the cards can also be positioned on a horizontal shelf on the housing directly above the corresponding card and light. The lights are connected in electrical circuit that is arranged so that each light is illuminated in sequential progression. A membrane-type switch is connected in the circuit and is located remotely of the housing. Through manual operation of the switch, the light progression is stopped at the selected card and/or object that expresses the student's answer or need. When the light progression is stopped, the selected light will blink repeatedly. By reactuating the switch, the light progression is re-established.
