Portable Braille and Screen Readers

I want to find a piece of free software that will voice the text on any page highlighted. I also want a device like a mouse that will interact with a blind person by raising dots on a pad in the form of braille. It could be an output device for a blind person instead of a screen. The device could also be clickable, perhaps on certain braille bunches. They could click on option word 1, 2, or 3, and feel information from a different area. This could be palm and 3 fingers, in variable size.

I would accomplish this with a matrix of small raisable plates in the device. It would probably have a resolution of 200X300 dots, some moving in bunches for size control, with their height controllable as well to form rounded bubbles. The top 50X300 would be 3 clickable segments, with that data input into the computer. This could be an endless interactive story with a blind person, which seems like an attractive option. The device could even be rollable like a mouse to add more interactivity, perhaps as analog level data.

It'd be plug & play, require no visual input into the computer, and begin with Hello! It might also make certain beeps. It could contain a RAM stick for the basic commands. I imagine all data could fit on a 256 mb flash card, and a 1gb stick would last for the life of a human.

Make it be!
