Okay, so you know how when you're using a computer or a phone, there are lots of buttons and things you can click on to do different things? Well, sometimes those buttons and things are hard to understand or use, especially if you can't see very well or if you have trouble moving your fingers around.
Bobby is special software that helps people who have a harder time using these buttons and things on their computer or phone. It makes it easier to navigate around and find what you want to do. It can be customized to meet individual needs, like making the buttons bigger or changing the color of the text.
So, think of Bobby like a friend who helps you use your computer or phone easier!
