Yesterday, the parent of a child that I see, told me that my room was not comfortable for him, visually. He has a form of autism, himself, and has become an invaluable consultant to me on many things. I thought that I had made our therapy room visually comfortable for children with autism by choosing a soft light color for the walls and carpet, choosing solid and cool colors for the mats and avoiding florescent lights. But, apparently, there is more that I need to do.
Here is one source of information that I found as I have renewed my study of autism friendly room design: http://www.designautism.com/10tips/10tips.html
