John LeSieur in the software business realised that his 6-year-old grandson, Zackary found computer useless as he suffered from autism. So he build Zac Browser For Autistic Children in honor of his grandson, and made it available to anyone for free. The Zac Browser disables irrelevant keyboard buttons like "Print Screen" and turns off the right button on the mouse. That removes commands most children don't need anyway, and it reduces the chance an autistic child will lose confidence after making a counterproductive click.

LeSieur didn't create the browser by consulting with people who are considered experts in disorders on the autism spectrum. All that helped him was his experience at the company he runs, People CD Inc., essentially designed the Zac Browser to meet Zackary's needs, and figured that the approach would likely help other autistic children.
