You have really specific ideas which makes me think you can self study. Institutional learning can be wider focussed and might not be as useful. 1) I would suggest starting the business right now. You have a day job and can bank roll it the initial stuff. Give yourself a budget and maybe a time and place to work on it? Do you have time to study on the side? 2) Next, find the type of customer that you want to work with and start seeing what you can find on the market to fit their needs. This way you can find a niche. Is it kids, adults, veterans? Is it mobility, seeing, hearing, etc? 3) Start researching the sort of things that are being created. (ex: The walking robots, robot cars, etc.) Maybe start communicating with researchers directly. You might end up finding one to study this exact thing with. 4) Try to connect a technology you can replicate with customers that you want to help and figure out what needs to be done to connect the two. You may even start just by helping people with off the shelf products and improving them. This can be a good time to put together a business plan if you need funding to pull it off. You may also find yourself just building a series of prototypes in your spare time. Enable a few kids to walk and money will find you.
