I know many families with children on the spectrum that would benefit from personalized video clips for their children's development. Have you seen my video clips? https://www.youtube.com/channel/UCYc6IlHhZiloQDNYaE9WXJg Check out my website at http://www.eikonabridge.com/ as well.
Most parents have limited computer skills. I find it frustrating. Virtually all essential multimedia tools are free and publicly available. Yet when it comes to drawing pictures for their children, parents won't do anything. And their children just become underdeveloped, due to the lack of efficient communication between adults and children. We are in year 2015. We are not in 19th century. The fact that parents can't pick up new skills is truly frustrating to me. It tells me that we have a failed educational system: in the past, we never taught our children to teach themselves. You don't even need to be a teenager to be able to make animated video clips. You just need to know how to use a mouse and a keyboard. There are plenty of kiddos making video clips on the internet nowadays. Those kiddos never needed to take any course in multimedia production: they learned everything themselves through Googling. Yet parents are totally incapable/unwilling of doing the same.
To me, intellectual disability, sensory problems, social problems, all stem from underdevelopment. And underdevelopment stems from lack of communication. And lack of communication happens because nobody is talking to their children visually, like the way I do with my children.
I'd tell your son to check out my video clips, and let him teach himself about using MS Paint, GIMP, Audacity, EZVid, and the like. Learn to create animated video clips by using a camera and a tripod. Go out and hang around with families with children with autism. Make video clips for their children, draw pictures for these children, and help them with skills such reading, or math (e.g: word problems).
When enough people start to do that, and when enough people realize that that is the right way of dealing with autism and help children develop, more things can happen.
As for your son, you've gotta have faith. The brains of the children on the spectrum have more connections than the brains of neurotypical children. This means people on the spectrum are capable of learning and improving at any age. The problem is not with these children. The problem is with us, the adults. As a society we have failed miserably in communicating with our children. They are visual, but how many parents out there have talked to their children, visually?
