I am learning to use a new device in school this year. It’s called a Monarch. It renders tactile graphics, Braille on a refreshable display and I can even use it for graphing in math. It raises the graph up so I can feel it and measure the points. I can also download my text books on it to read in Braille. An added bonus is that it can be hooked up to a computer monitor so when the teacher walks around she can see what I am typing or graphing in print on the screen. Win win for everyone! Someone
