To reduce complexity on a concept/choice board, I used corrugated black plastic to create the board. I used black Velcro so the Velcro would not become another item in the array. (It disappears against the black plastic).
I wanted to be able to notice any visual behaviors so created a window. I was concerned that my eyes and face would become another item in the array. Using black screen like the kind used in window screens, I covered the peek hole. Now this board can be held up at the child’s best distance and at her eye level. I can watch exactly where she is looking and at what she is looking no matter how quickly she looks. I can reach around the board and create movement to draw her visual attention to the described item.
This is really helping the team understand whether this child understands the visual information, the concept being discussed and or the choices being made. I can present 1, 2, 3 or 4 icons on this board depending on the child’s assessed array tolerance using the CVI Range (Roman-Lantzy 2007)
