ABSTRACT:
A laser driven optical communication apparatus for permitting verbally impaired or disabled individuals having limited physical mobility to communicate with others. A laser device generating a coherent beam of light is provided wherein the individual directs the beam of light upon an interface screen towards forming images understandable by others. The interface screen serves to cause the beam of light to be reflected and made visible. An optical receiver comprising a modified video camera directed toward the interface screen receives the reflected image and serves to enhance the persistence of the image to cause the beam of light directed by the individual to appear as a single continuous image upon an associated display. A video cassette recorder may be incorporated to permit the images to be stored and replayed at a later time. The present invention may also be used to permit a speaker to "draw" images upon a display being projected upon a display screen such as in a conference hall setting.
