Photo One: Landscape photograph showing two smiling male adults from the waist up and a computer workstation. On the left is Greg Smith seated in his power wheelchair. He is 37 years old with a youthful face, brown hair and wire rimmed glasses. His trunk is secured by a broad black seat belt just below the shoulders. He is wearing a light blue, long-sleeved business shirt open at the collar with no tie. Behind his head is mounted a large round red head switch the size of a saucer. On Mr. Smith's right arm rest is attached a eight inch vertical length of chrome goose neck; at the top of this goose neck is Mr. Smith's scanning display, a black plastic box about five inches wide and 3 inches tall. The display has four lights that indicate which direction the power wheelchair will proceed in when Mr. Smith presses his head switch. In front of Mr. Smith at chest level is his voice output communication aid. It is supported by a piece of chrome pipe. This communication aid is a box approximately thirteen inches wide, ten inches tall and three inches deep. In the center of the photo is Donald Spaeth. He is kneeling so that his head height is about the same as Greg's. Mr. Spaeth is 50 years old with thin greying hair and wire rimmed glasses. The right third of the photograph is occupied by Mr. Smith's personal computer stacked on a roll-away cart. The color monitor is on and displaying the American On Line startup screen. To the right of the montor is a tower style CPU. Below and in the foreground are the keyboard and mouse.

Landscape photo taken over Greg Smith's right shoulder. It clearly shows the keyboard of his voice communication aid. This communication aid is called a Liberator. The keyboard is a grid of picture marked membrane keys. Each key is three quarters of an inch in diameter. The keys are arranged in eight rows and sixteen columns. This communication supports scanning access. Each key is marked with a small red light. By means of circuitry inside the Liberator, the lights can be made to sequentially illuminate row by row or column by column. Mr. Smith uses a single thumb switch to signal the liberator when the row and column containing his desired key are illuminated. The Liberator processes that keystroke just as if that key had been manually pressed.

Lanscape photo showing a close-up view of Mr. Smith's left hand. The back of Greg's hand is resting on his left thigh. His left hand is inserted into a flesh colored plastic hand brace which provides a mounting point for a small one inch long, half inch wide thumb switch. Mr. Smith's left thumb is the only part of his body he can reliably control.
